How to disassemble the split system daikin indoor unit. We clean the split system ourselves - dismantling the indoor unit. How to remove the outdoor module while preserving freon - video
There is a lot of information on the Internet, articles and videos on this issue, let's try to summarize with you a little and look from the technical side at the process of cleaning and maintaining a split system (air conditioner) both with our own hands and when calling specialists.
To begin with, I would like to answer a question that worries everyone and everything.
How often should the air conditioner be cleaned? There is no single answer, it depends on the operating conditions and habitat. Air conditioning in an apartment is one thing, and air conditioning in a Bar, Cafe or Pishcheblok is another matter. We will assume that we have an ordinary household air conditioner in an apartment, with a standard power of 7-12 kbti.
We answer: air conditioner cleaning and maintenance annually!
What is the correct cleaning of the air conditioner?
The second question is what is meant by cleaning a split system (air conditioner). Cleaning the filters of the indoor unit can also be called cleaning, but there is little sense in such “cleaning”. Cleaning the air conditioner (split system) is primarily cleaning the heat exchangers (evaporator and condenser) of the indoor and outdoor units, cleaning the fan, cleaning the squirrel wheel, cleaning the drainage system.
How to clean split system filters?
Cleaning the split system filters should be accepted by default, the filters should be cleaned every two to three weeks. This lovely girl will show you how to do it right.
Well, how to clean the split so that it is of real use?
It is difficult to do this without a steam cleaner and a high pressure washer, but you can get by with improvised means, it is advisable to do such cleaning before each summer season.
How to disassemble and clean your home air conditioner
I found a very good video on the Internet on how to properly clean the indoor unit of a split system on my own, look:
What is the difference between cleaning and maintaining an air conditioner (split)?
Maintenance is carried out by specialists using a steam cleaner and a sink, which in principle you can do yourself, but the key difference between maintenance and cleaning a split system is that specialists measure the freon pressure in the system, and, if necessary, refuel the required amount of freon to split refrigeration at an acceptable level. Diagnosis of electrical and installation connections is carried out automatically. In other words, cleaning the split system is part of the maintenance of air conditioners. Here I found a decent video, good guys, they explain everything in detail, we look:
After watching these videos and reading the article, I think it has become a little clearer to you all what kind of animal “cleaning air conditioners” and “what it is eaten with”. And you decide what to do, clean your split yourself, or call specialists. But I would like to summarize all of the above:
1) You can clean the air conditioner filters yourself every 2-3 weeks
2) Cleaning of the indoor unit (condenser, squirrel wheel, drain) must be carried out every season on your own or by calling specialists
3) Maintenance (comprehensive cleaning of the indoor and outdoor units, refueling with freon) must be carried out once every two or three years by calling the specialists
Numbers and prices
The average cost of cleaning a split system in Krasnodar is 1300-1500 rubles per season. This includes cleaning the indoor and outdoor units of the air conditioner, with analysis. With a steam cleaner and sink, sometimes just a steam cleaner. In good services, during the high season, there is usually a queue of at least 2-3 days. There are more, and then how lucky.
The annual loss of freon (microcracks and microleaks) laid down by the manufacturer is 5-7%.
Refueling with freon, if necessary, is not included in the cost of cleaning, and can be 500-1000 rubles additionally, depending on the amount of freon.

Servicing the indoor unit of the air conditioner ...
Hi all! At the request of my friends and accomplices in general, I want to write a post about the maintenance of air conditioners, because this is already relevant at the moment (I hope the moderators will be understanding)! The fact is that consumers are often misled by offering them air conditioning service ANNUALLY!!! This is not necessary, because everything depends on the degree of contamination of the room where the air conditioner is located!
How to understand that cleaning is already inevitable? Let's look at the process of cleaning the indoor unit, perhaps you yourself are able to perform this operation:
So we have a regular internal block:
Below, in order not to mess up the repair, we glue the film onto ordinary masking tape:
Open the lid, remove the mesh filters and rinse them under running water (this can be done at any frequency, but at least once every 2 months!)
Now we remove the entire upper part of the case, along with the cover ...
We unfasten the bath (through it the condensate enters the street) ...
and then enjoy the terrible spectacle! Here we can already understand what we breathe including a clogged air conditioner ...
We turn on 22-25 degrees on the remote control (do not turn on the minimum ... never in the heat, not a single condo will give you 16-17 degrees !!! You will stupidly kill it!) and enjoy the coolness!
… I will talk about the outdoor unit later! I inform you that I have been engaged in air conditioning and ventilation since 2000 and I am ready to help with advice, and indeed in this area!!! So ask! I will answer later, in the evening I will answer everyone, because now there is a lot of work .. I am running away) Have a good day everyone!
Do-it-yourself split system cleaning
How to remove the air conditioner from the wall with your own hands
disassembled indoor unit. With how to remove the air conditioning compressor and the outdoor unit itself with your own hands ... Remove the protective cover from the housing; …
The dismantling of this household system is carried out for subsequent repairs or when moving, many users solve the problem simply - they call the masters from the service center. A prudent owner who has the skills and desire can save money and do everything on his own, but we will tell you how to properly remove the air conditioner, while avoiding mistakes and negative nuances.
Any modern split system, which includes domestic air conditioning, consists of blocks for indoor and outdoor locations. They are connected by two lines through which the refrigerant moves. circulates through a tube of smaller diameter freon in liquid form from the indoor unit to the outdoor unit, it runs in the opposite direction along a thicker copper tube, but in a gaseous state.
This is where the problems lie that can spoil all your actions when trying to remove the air conditioner yourself.
- As a result of improper shutdown of main pipelines, partial or complete freon loss.
- Air containing moisture can get into the tubes and the heat exchanger, which is fraught with breakdown when the air conditioner is operating in a new place - incompressible moisture enters the compressor and disables it.
- Small particles entering the copper pipes when they are pulled through the wall or during improper transportation leads to a quick breakdown of the system.
- Particular attention should be paid to the threaded leads soldered to the tubes, if they are damaged, a very expensive repair will be required.
- Incorrect wire disconnection. If you do not put special marks on the terminals, it may lead to incorrect connection in a new place.
- Cutting too short drainage tube, which removes condensate outside the outdoor unit, you doom yourself to its premature complete replacement.
- During transportation of the product to a new place of service, there is a danger of losing small fasteners and parts if they are not securely fastened after disassembly.
All of the cases listed above lead to a very expensive repair of the entire system, so before you start dismantling the air conditioner with your own hands, read the instructions.
Preparation
Before dismantling the split system with your own hands, you need to prepare a tool, not a simple one from your home arsenal, but a purely professional one, as shown in the photo:
Many users do not take seriously the advice of professional craftsmen on how to properly dismantle any split system. As a result, the shutdown is carried out with numerous violations: they dismantle the product without pumping freon into the air conditioner, it leaks, which will not be as easy to make up as many people think.
A new filling of the entire system with refrigerant will result in serious financial costs:
- first, the master will check the integrity of all pipelines - 600 rubles;
- refueling an air conditioner with a power of up to 4.5 kW - up to 3 thousand rubles;
- the same actions with equipment power up to 7 kW - up to 3.5 thousand rubles.
With the most minimal scenario for household air conditioners, this operation will cost you at least 4 thousand rubles, depending on the refrigerant used.
Freon descent
There are three ways to dismantle the air conditioner with your own hands:
- disassembly with the release of freon;
- save gas inside the air conditioner approximately or “by eye”;
- completely save freon with the help of professional equipment, using a special technique.
The third option gives the best effect without any loss, but many users use all methods. Experts advise to completely store the refrigerant so that there are no problems when installing dismantled equipment in a new location.
To properly dismantle the air conditioner, you need to know the design of the split system, which consists of a closed circuit filled with freon. The main components are a compressor, an evaporator with a condenser and a system of copper pipes that connects the entire structure and ensures the supply and withdrawal of refrigerant.
This is how a schematic device of a modern air conditioner or any split system looks like:
To turn off the air conditioner yourself without losing freon, you need to pump it into the condenser, for this, when the equipment is operating in cooling mode, you should close the valve between the product and the thin-diameter tube. When all the refrigerant is pumped into the condenser for a minute - that is how long it will take for the gas to be completely pumped - it is necessary to shut off thick tube valve, turning off the freon supply, and "close" it in an impromptu trap.
Dismantling
Before dismantling the outdoor unit, you must disconnect copper tubes, but in practice they are not reused, because building them is strictly prohibited. It is necessary to cut them off at a distance of about 200 mm from the fitting and caulk the cuts for complete sealing.
Attention! When the product is disassembled for a long time, the tubes are filled with nitrogen, provide tightness to prevent oxidation of the inner surface.
outdoor unit
The instruction says: after working with copper tubes, you need to remove insulation, as a rule, all masters work together, one indoors, and the second outside. Thus, dismantling is faster: the partner turned off the power and now you can disconnect the wires at the place of their connection, previously by marking the terminals.
The tubes are straightened by hand so that they pass through the holes in the wall without interference, and the end of the cable is screwed to them to remove it inside the room.
After that, we unscrew the nuts that hold the outdoor unit on special brackets, together with an assistant carefully remove the unit and move it inside the apartment. Lastly, the brackets are removed from the wall of the building.
Important! The dismantled outdoor unit during transportation and during storage is located only vertically in order to exclude mechanical damage from shaking - it is inserted into a box, with foam at the bottom.
Compressor
Sometimes only the outdoor unit is dismantled, for example, if only the compressor needs to be repaired, and the indoor unit of the air conditioner remains in place. During similar operations, the indoor unit of the split system is also not touched.
The main condition is to properly dismantle the compressor:
- remove the cover from the outdoor unit;
- then detach suction and discharge pipes;
- all electrical wiring is turned off;
- the fasteners of the condenser and fan are unscrewed;
- remove the capacitor from the block housing;
- access to the compressor is open - remove the fasteners and dismantle it.
With such actions, the risk of damaging the pipelines is eliminated and there is a real opportunity to repair other elements located in the outdoor unit case, if necessary.
indoor unit
Dismantling the indoor unit of the air conditioner has its own very specific nuances, without knowing which all your efforts will be useless, and in some cases careless actions can lead to breakage of rather delicate fasteners, for example, evaporator latches or latches holding the unit on the rails.
To understand how to remove the air conditioner from the wall, you need to study the instruction manual, where there is a section that interests you. Many users will not be able to do this operation - they will have to turn to professionals.
Remove indoor unit the air conditioning system will turn out only after removing the front panel, then you still need to disconnect all the electrical wiring, the inlet and outlet pipes of freon. It is necessary to disassemble the plexus of wires carefully and without fuss. But this is not all the tests - manufacturers have reliably closed access to evaporator latches that dismantling is carried out only by specially trained people.
Access is closed by a cover, the latches of which are quite tightly pressed against the wall - you can get close to them using two screwdrivers with a very thin sting. Your partner must hold the entire block during this laborious process.
After removing the evaporator, you can unscrew mounting plate, which closes access to the electrical wires supplying the product and the freon pipes hidden in a special gutter inside the wall. The last to unscrew the decorative box, which runs along the outer wall to the very outdoor unit.
The disconnected wires are neatly twisted and folded into a separate box for transportation. To help home craftsmen, there is a video on how to dismantle the air conditioner on your own, without contacting specialists:
Dismantling in winter
Many users are interested in the question: how to remove a split system in winter, when due to low temperatures it is impossible to pump refrigerant into the condenser. The oil in the compressor will thicken, and all attempts to turn it on can end very badly.
If you have a special model equipped with a kit where there is a heater for the compressor crankcase and the entire drainage system line, as well as a block that slows down the rotation of the fan, then your intentions will succeed. In its absence, you can use a special refrigerant recovery station, which is connected similarly to a manometric manifold.
A few more practical tips: you can start dismantling yourself only when you are completely confident in your own capabilities, and there is a qualified partner. Also, the presence of a special tool makes the job much easier.
Nowadays, many owners of houses and apartments equip their homes with climate control equipment that is able to maintain a comfortable microclimate in the premises. One of the most popular appliances for this purpose is the air conditioner. Modern models can have not only one function - air cooling, but also be "all-weather", multifunctional, that is, at any time of the year, maintain a normal temperature set by the user in the rooms.
However, the microclimate will actually be comfortable, and the use of air conditioning will not harm the owners if certain important conditions are met. In particular, such devices require some care, so they are usually serviced by professional craftsmen. To do this, often contracts are concluded with the company that conducted, for further service maintenance. They also resort to one-time calls for masters - there are a lot of ads of such content in the advertising press.
But such a service is not cheap, so many device owners are interested in the possibility of self-care for them. One of the important points in the maintenance of climate technology is to keep all its components, especially filter blocks, clean. Therefore, the question arises of how possible it is to clean the air conditioner with your own hands? Yes, it's doable! And if you understand at least a little about the design of the device and know how such a process is carried out, then, indeed, you can put it in order on your own.
Why is it necessary to clean the air conditioner?
Is it really necessary to regularly clean the air conditioning equipment? Maybe it's just another "money scam" on the part of manufacturers and service companies? No, everything is much more serious!
Devices that cool or heat the air drive it through the filtering devices installed in them, since it is unrealistic to completely get rid of dust in the premises. Accordingly, quite soon a large amount of dirt and dust is collected in the filters.
Therefore, if you do not carry out periodic cleaning of the air conditioner, then the following problems will certainly arise:
- There will be a clear drop in the functionality of the device, that is, a significant decrease in efficiency due to the difficulty of passing air through the filters.
- If the air conditioner is not cleaned or is not done regularly, the heat exchanger with the freon inside it will start to overheat, which will increase the load on the compressor, and as a result, the device will quickly wear out.
- Increased humidity and dust deposits inside and outside the filters contribute to the active reproduction of dust mites and various bacteria. Among pathogenic microorganisms, the most dangerous is legionella, which causes a serious lung disease - legionellosis (it is also called "Pittsburgh pneumonia"). Together with the flow of air passing through contaminated filters, spores of fungi and mold can spread throughout the premises, which can easily provoke allergic reactions, lead to asthmatic attacks and dermatitis.
- Unpleasant smell in the room is probably the smallest trouble of all, which entails the pollution of the air conditioner.
It should be noted that air conditioners that are installed in multi-storey buildings on the uppermost floors are less susceptible to rapid clogging, since many times less dust is concentrated at high altitudes than in the lower layers of air. But this does not mean that they will not have to be cleaned - there may simply be less mud deposits.
Much more often it will be necessary to clean and disinfect devices installed in houses located near highways, in industrial areas of the city and in areas under construction, since the air is most polluted there.
Another negative phenomenon for climate technology is poplar and other plant fluff, which is capable of literally clogging air conditioner filters in a short time. Therefore, if the area where the house is located is planted with poplars or other trees (shrubs) with a similar form of flowering, then climatic devices must be monitored with particular care.
The air conditioner, as a rule, itself begins to “declare” that it needs preventive maintenance if it was not cleaned on time. So, such manifestations can be:
- Constant or temporary noise or crackling when the device is turned on.
- Unpleasant smell of dampness or preli.
- A clear decrease in the cooling capacity of the air conditioner.
- The device began to consume too much electricity with the same or even reduced output - this can be seen by taking readings from the meter.
- The indoor unit began to leak while the air conditioner was running.
Prices for popular air conditioners
If at least one of the above signs appears, then this indicates that the device needs urgent preventive maintenance, otherwise the air conditioner may soon fail.
It is best to prevent such a situation, since it can result in the replacement of individual parts or structural blocks that have failed due to the banal carelessness of the owners, which leads to significant costs.
- Be sure to clean the filters of the device in the spring, before intensive work in the summer.
- Prevention should also be carried out in the fall, before the cold period, when the air conditioner is switched to the room heating mode.
- Unscheduled prevention - urgently, in any case, if the signs mentioned above appear.
Thanks to timely preventive maintenance, the air conditioner will work out the entire resource put into it without any problems, which is usually 8 ÷ 12 years and even more.
Cleaning the indoor unit of the split system
The design of the indoor unit of the air conditioner
To figure out where to start preventive work, and what exactly should be subjected to the most thorough cleaning, you need to at least get a little familiar with the design of the device. Most often, split systems have recently been used, and first of all, the indoor unit of the air conditioner most accessible to the user affects the microclimate in the room. Let's start with him.
So, the indoor unit consists of the following components and parts:
1 - Front panel of the device - This is a plastic case with a grille. Through it, the air from the room enters the device for cooling (or heating), naturally, with the transferred dust. The panel can be easily removed - if necessary, carry out maintenance work. For this, a system of locks (latches) is provided.
2 - Coarse filter- This is a fine-mesh polymer mesh, which is designed for collection of large dust particles from the air, fluff, villi of animal hair and other similar suspensions. Such a filter requires cleaning, or at least control, at least twice a month. In innovative models, some manufacturers provide for automatic cleaning of this filter. The coarse pre-filter is located immediately behind the front panel of the device.
3 - Fine filter. Usually, not one, but several filters are installed in a cascade, which can clean the air from various contaminants. Each of them has its own structural features:
- carbon filter, containing activated carbon, and designed to remove unpleasant odors and neutralize harmful substances. This type of filter is not cleaned, but replaced completely, on average every 4-5 months.
- Zeolite filter made from porous mineral - zeolite. This version of the filter is able to absorb chemical compounds from the air, which include heavy metals, so it is more efficient than carbon. In addition, unlike coal, the zeolite filter can be washed with water and can be used for up to five years with regular maintenance.
- Electrostatic the filter cleans the air from fine dust by creating an electrostatic field. Dust particles, passing through it, become electrified and settle on oppositely charged plates. The service life of this filter is unlimited, and it is cleaned as it gets dirty.
- Plasma filter works on the same principle as electrostatic. Under the influence of electrical voltage, a low-temperature plasma is formed in it, capable of destroying harmful substances and small dust particles, at the same time giving them a negative charge, due to which they settle on a positively charged plate. The plasma filter is also designed to remove odors and smoke. The service life of this filter is unlimited, and it is cleaned as it gets dirty.
- UV filter necessarily includes an LED of a certain spectrum of luminescence, which is capable of disinfecting the air of the room, destroying viruses and bacteria. UV light can also prevent the growth and spread of mold and mildew inside the air conditioner. This option can be used alone or in combination with a photocatalytic filter.
- photocatalytic filter is a porous substance titanium dioxide coated. This filter adsorbs on its surface all the pollutants of the air masses passing through it, including toxic substances, unpleasant odors, fungal spores, etc. Getting under the influence of ultraviolet, which is included in the complex photocatalytic filter, all toxic substances decompose into water and carbon dioxide. This type of filter does an excellent job with both inorganic and organic air pollutants. The service life of this filter is limited only by the "life" of the UV lamp.
- Antibacterial filter. Designed to neutralize various pathogenic microflora - microbes and viruses. It contains such natural active ingredients as:
- catechin - an antiseptic found in apples and green tea;
Wassabi is a plant with antibacterial properties.

air conditioner filter
- Antioxidant filter It is made on the basis of flavonoids, which contribute to the conversion of free radicals into inactive chemical compounds.
4 - Fan to circulate air through the air conditioner. As a rule, the fan can have three to four speeds of rotation.
5 - Evaporator. This, in essence, is a radiator in which freon evaporates, due to which the air passing through it cools.
6 – Horizontal blinds, regulating the direction of air flow vertically. They are controlled remotely, from a remote control, through an electric drive installed in the air conditioner housing.
7 - Display panel located on the surface of the indoor unit of the air conditioner. On it, using LEDs or a digital display, the operating modes of the device are shown, including the set temperature.
8 - Vertical blinds regulate air flow in horizontal directions. They can be moved manually or remotely, depending on the equipment of the device.
In addition to the above structural elements, it necessarily contains others that are not shown in the figure:
9 - Condensate tray. This part is placed under the evaporator, and it serves to collect water, which is then discharged through a drain hose from the air conditioner to the outside.
10 - Control electronic board. A central microprocessor is installed on it, with the help of which the device is controlled. The board is usually located to the right of the indoor unit of the air conditioner. Usually, a terminal group is also located near it - for connecting the air conditioner to the mains and for electrical switching of the indoor unit with the external one.
11 - Fittings located on the bottom rear of the indoor unit. Copper pipes connected to them serve to connect the outdoor and indoor units - this creates a closed circuit for the circulation of the refrigerant.
Several preparatory operations
Due to the fact that the split system air conditioner consists of two blocks, outdoor and indoor, their cleaning also differs somewhat, which is important to consider when starting its prevention. On the outer block, attention will be focused below, but for now we continue to consider the inner one.
- Before starting preventive work, it is necessary to protect your hands and respiratory tract, since you should not forget that in the air conditioner case there is a hotbed of viruses and dangerous bacteria that got there along with dust from the air. They can easily enter the body, which threatens with serious diseases, even for a person with excellent immunity.
- Next, the air conditioner must be disconnected from the mains. It would seem that this is an understandable action for everyone, but sometimes they forget about it, and remember it only at the moment when the first electric shock occurs. Well, if it is light, only in the form of tingling ....
- Then, it is recommended to cover the floor area under the air conditioner with plastic wrap, which, after cleaning the device, is best to simply throw it away. It is especially important to protect the floor surface if the air conditioner has been working for a long time without maintenance, and a large amount of dirt has accumulated in it.
Procedure for general cleaning of the indoor unit
Sometimes it is necessary to clean only the filters of the instrument, as they are the first to get dirty. I must say that washing them yourself is not difficult at all. Therefore, it is recommended to carry out this procedure almost weekly, making it a rule to perform these simple steps before cleaning an apartment or house. Naturally, such frequent preventive maintenance is necessary if the device is used constantly.
If the air conditioning equipment is put in order regularly, the house is kept clean, and thanks to this, the dust does not have time to clog all the pores of the fine filters and the coarse cleaning cells, then it is enough to dry clean with a vacuum cleaner.
If the filters of the air conditioner are heavily clogged, then they will have to be additionally washed with special detergents, and then with water.
Detergents are purchased in specialized stores for climate equipment or in service centers for its maintenance.
| Illustration | Brief description of the operation to be performed |
|---|---|
 | So, the first step is to open the front cover of the air conditioner, on which the protective grille is located. This process is simple, especially since all owners need to do it quite often, checking the degree of contamination of the device. Next, the coarse filters are carefully removed. They can also be fixed in different ways. So, in some models, they can be removed without even opening or dismantling the front panel. |
 | Then the cover covering the fasteners is removed. In various designs, this panel can be fixed in different ways - in some models it is enough to simply remove it from the latches, while in others it has to be unscrewed. |
 | In this model, the plastic case of the indoor unit is fixed with screws located at the bottom of the structure. They are closed with protective plates, which must first be opened. For convenience, you can use a regular screwdriver - it picks up the closing screws of the cover, and then unscrews the fasteners themselves. Work must be done carefully, as plastic parts are quite fragile. Having unscrewed the fasteners, it is also necessary to dismantle the display panel connected to the electrical part of the air conditioner from the housing. This element, together with the wires, must be temporarily placed to the electrical unit. |
 | After unscrewing the screws, the plastic case of the air conditioner is removed. In different models, it is also fastened in different ways, therefore, having unscrewed the screws on one side, you should not pull the case. It must be gently pulled towards you, and if it is not removed, then you will have to look for places where it is additionally fixed. Next, the fine filters should be removed from the air conditioner. |
 | The next step is to make sure that the electrical unit of the device is protected from splashes of disinfectants and detergents, as well as water jets. Ordinary hospital shoe covers are perfect for this purpose - thanks to the elastic band located on them, they will fit snugly against the device, and the protection will not fall during operation. |
 | Now it's time to prepare for cleaning. For this purpose, you can use a large, durable plastic bag, but this “device” cannot guarantee reliable protection of the surfaces of the room from the ingress of detergents along with dirt from the air conditioner. In specialized stores or on online trading platforms, you can purchase a kit specifically designed to protect the floor and walls during the cleaning of climate equipment. Such a set is more convenient, since it provides almost all the necessary elements both for its fastening and for draining dirty water into a bucket. |
 | The service package includes a large specially shaped plastic bag with a funnel in the lower central part, on which a plastic spout is attached for easy fixing of the outlet hose. In addition, it contains a polyethylene apron installed between the wall and the bottom of the air conditioner, holders like stationery, with which the stiffening ribs inserted into the edges of the bag are fixed, and a tape for hanging it under the air conditioner. Unfortunately, the kit does not include elements that act as stiffeners, as well as a hose for draining dirty water. Therefore, you will have to take care of these details yourself. To do this, you will need thin plastic or metal tubes, or even ordinary wooden glazing beads, which are used to fasten window panes. The length of these rigid inserts should be: 600 mm - 2 pcs. and 1200 mm - 2 pcs. The section of the hose should correspond in cross-section to the diameter of the spout fixed on the plastic bag - so that it fits snugly against the drain spout. |
 | In the bag along its edges, channels are provided in which stiffeners must be installed and fixed with stationery holders. A belt is fixed on one side of the package, with which the package will be hung on the air conditioner. When ready for use, this fixture looks something like the one shown in the illustration. |
 | Next, an apron is taken - this is an ordinary polyethylene sheet, which is slipped under the body of the device and fixed to the wall with masking tape. It will protect the wall from getting dirty lumps of wet dust. Then, a package with stiffeners is hung under the air conditioner, the belt is put on top of the device body. After that, a hose is put on a plastic spout, the second end of which is lowered into an ordinary plastic bucket standing on the floor. |
 | Further, if thick dust layers are found after opening the indoor unit of the air conditioner, they can be removed with a soft brush or collected with a vacuum cleaner. After such a superficial removal of accumulated deposits, it will be easier to flush structural parts from more deeply ingrained dirt. |
 | After removing the external dust, you can proceed to the preparation of a washing disinfectant solution. It is made from products specially designed for cleaning the air conditioner. The solution is mixed in accordance with the proportions indicated on the packaging of detergents. To apply the solution, you will need a spray gun, in which the jet can be adjusted according to the spray diameter. |
 | The next step is to apply the finished solution to all elements of the indoor unit. Especially carefully it is necessary to spray the fan and radiator of the device. A huge amount of dust collects on the impeller blades of the fan roller, which eats into the surface of the material from which it is made. Therefore, it is simply impossible to clean this part of the air conditioner from dirt without special tools. The radiator is equipped with numerous heat exchange plates, between which dust also accumulates, and it is quite difficult to remove it with plain water, so you can’t do without special equipment either. The disinfectant cleaning solution should cover all the details of the structure, since if unwashed areas remain, they will later become a favorable place for fixing new layers of dirt. |
 | Detergents are usually applied in two stages. Liquid detergent disinfectant (in this case, Alfadez) is sprayed first, followed by Winns 30202 detergent, which is sold in cans and produces abundant foam, which helps to better soften and exfoliate the dirt. After the detergents are applied to the surfaces of the indoor unit, they must be left for some time, approximately 20-25 minutes, so that the solutions corrode the outer and inner dirty layers. When the foam has settled, a control check can be made to see how easy the dirt will be removed. |
 | After the foam settles, you can start flushing the split system with water supplied under high pressure with a thin stream. With self-washing, you can use the same spray gun, but this will take a lot of time and a large amount of water. |
 | When flushing the system, the dirt on the bottom of the air conditioner body will drain into a plastic bag suspended under it, and from there into a bucket. It is important to ensure that the container is not overfilled, as dirty water and disinfectants can seriously damage the flooring. |
 | Flushing the indoor unit of the split system starts from its rear. Then the radiator is thoroughly washed, after which it is necessary to clean the inside again, since dirt from the heat exchanger grill may be on the surface of the fan blades. |
 | At a time when the indoor unit will soak under the influence of detergents, you can clean the parts of the plastic case removed from the structure. They are also sprayed with disinfectants and detergents. If necessary, the dirt on them can be rubbed with a soft brush, and then these structural elements are washed under running water. |
 | In addition to the rigid parts of the body, it is necessary to rinse the coarse air filters. First, they also need to be sprayed with detergents. Then they are left for a while - until the dirt is separated from them, and then washed under running water. |
 | The filter is washed, but not wiped - the water should drain from it spontaneously, and it should dry naturally. When washing the filter, do not use ordinary detergents, as they can negatively affect not only the filter itself, but also the indoor unit of the air conditioner. In addition, do not forget that the molecules of solutions of household chemicals will later get into the air of residential premises. |
 | It is more difficult with fine filters, since among them there are options that cannot be washed, and dry cleaning will not bring results, and therefore they will have to be replaced with new ones. So, I would like to remind you that replaceable filters include coal, antibacterial, antioxidant, and also vitamin. Washable filters include electrostatic, photocatalytic, plasma and zeolite filters. New replacement filters are usually sold at air conditioner service centers or at service centers of manufacturing companies. |
 | When all the insides of the unit and all the parts removed from it dry well, you can remove the hanging bag and shoe covers from the electric unit and assemble the air conditioner in reverse order. The fine filters (new or washed) are returned to their place, then the washed housing is fixed, the indicator panel is fixed to it, and the coarse filters are installed last. |
 | Now that the cleaning work of the air conditioner has been completed, you can turn it on, check its operation and proceed to normal operation, until the next maintenance. |
Cleaning the drainage system of the air conditioner
One of the common problems that air conditioner owners face is water leaking onto the floor or walls from the indoor unit. Most often, leaks occur for the following reasons:
- Due to the contamination of the drainage system of the appliance, when condensate cannot pass through the clogged pipe, and therefore begins to drain from the indoor unit into the room. In this case, the drainage system must be cleaned. Drainage clogging occurs due to the fact that the air conditioning units were not cleaned in time - the dust turned into dirt and clogged the tube.
- If the amount of freon (refrigerant) in the system is reduced, then the temperature of the evaporator also becomes lower, therefore frost forms on it and water does not pass into the pan, and also flows down to the floors of the room.
- If the air conditioner does not have a pressure regulator, then when the temperature drops outside, the pressure drops and in the system, as a result which also reduces the temperature in the evaporator. However, it should be noted that pressure regulators are usually installed in all modern models of air conditioners.
- Freezing of the drain pipe - this occurs if the air conditioner is used in winter to cool the premises.
- Another cause of stagnant phenomena in the drainage is wasps or other flying insects, which quite often clog the edge of the pipe located on the street.
If the drain pipe is clogged, then before proceeding with its cleaning, it is imperative to flush the drain pan, as well as other elements of the air conditioning system. Work on cleaning the drainage is carried out with the device turned off from the network and is carried out in the following order:
- The first step is to remove the coarse filters.
- Next, the lower narrow panel is dismantled, hiding the body mounts to the air conditioner.
- Then the drainage pan is removed - in each design this operation is carried out differently, but it is not difficult, and it is quite possible to figure it out on the spot. It is necessary to remove this structural element in order to clean it of dirt, and also in order to get to the hole into which water flows from the pan and to which the drainage tube is connected.
- The next step is to disconnect the drain tube from the air conditioner and connect the hose of the compressor (hand pump), steam generator or vacuum cleaner with a blowing function to it.
- Another option for cleaning can be a mechanical method. To do this, take a long, enough hard, but at the same time, a flexible wire (something like a television cable is good) that goes into a drain disconnected tube or directly through a hole in the tray. It is pushed through the entire drainage system. Thus, it should appear from the pipe facing the street, through which the condensate escapes.
- However, these are not all the steps necessary in this process, since it must be taken into account that the cork was removed from the tube, but the dirt in it still remained in the stacks. When the air conditioner is running, new dust will easily stick to these residues of dirt, and the plug will be restored. Therefore, the tube must be thoroughly rinsed. This can be done using a pump or a homemade device consisting of a plastic bottle and a piece of silicone hose put on its neck.
- To flush the drainage tube, it is recommended to use chlorhexidine, which is an excellent antiseptic and is sold in a pharmacy. For flushing, approximately 400 ml of liquid will be required.
- If flushing will be carried out through the drain hole, that is, without removing the tube from it, then the flushing liquid can be poured through it. The bottle with chlorhexidine has a spout, which allows you to perform this procedure without the use of improvised means. After 15 ÷ 20 minutes, the system must additionally be purged with a vacuum cleaner or pump. After cleaning the system, it is recommended to check it immediately. To do this, one and a half liters of ordinary water is poured into it again using one of the methods described above, which should freely pour out through a pipe on the street.
In the event that the air conditioner is equipped with a drainage pump, that is, condensate is not discharged to the street, leakage may occur for the following reasons:
- Failure of the pump - it may not work at full capacity or even burn out. In any case, the device must be checked, and for this it will have to be removed.
- If the float chamber is clogged and the float is fixed in one position, the pump will stop discharging water.
- The float or proximity sensor does not work.
- Air tube is kinked.
- Insufficiently good contact of the pump power terminals.
To find the cause of problems in models with a drainage pump, you will have to invite a specialist in the repair of climate equipment. It is not recommended to meddle in this system yourself.
Automatic air conditioner cleaning system
Some modern models of air conditioners are equipped with an automatic cleaning system. The principle of operation is quite simple - with a certain frequency, the device switches to idle operation, and the air passing through the filters dries all the details of the structure.
In addition to the usual automatic cleaning, ionic air purification is installed in some models. Thanks to the latter, dust particles are ionized, so they easily fall into the dust collector. In another version of the devices, water ionized dust is used to protect against the occurrence of unpleasant odors - this is a system of full ionization and filtration.
In addition, such air conditioners are usually equipped with touch sensors that can control the composition of the air. If necessary, they give a command to the automatic cleaning system to turn on.
These features extend the life of your air conditioner and make it easier to maintain. However, you should not think that you will not have to clean the device manually or call a wizard for this purpose, since the automatic system will not be able to remove and rinse its filters, and this is necessary to do, one way or another.

Cleaning the outdoor unit of the split system
The design of the external unit of the air conditioner
Now, having figured out how to clean the indoor unit of the split system, you need to consider how the preventive work of its external part is carried out.
Unlike the indoor unit, the outdoor unit is washed once a year, but it is still necessary to do this, as it is clogged not only with dust, but also with leaves, poplar fluff, small twigs and other debris. From this it becomes clear that it is absolutely impossible not to clean this part of the air conditioner. The most difficult thing is to carry out preventive measures if the device is installed on the upper floors of multi-storey buildings, in this case, specialists cannot be dispensed with.
The design of the external block consists of the following blocks and parts:
1 – Fan, occupies a large part of the body of the outdoor unit of the air conditioner. Its functions are to blow the heat exchanger-condenser.
2 – Capacitor located along the inner walls of the case, near the fan. It is a set of copper tubes, inside which freon is pumped, which is cooled by a working fan.
3 – Compressor provides circulation of freon on the general closed contour of the conditioner. This device is of two types - piston and spiral. The piston version of the compressor is more affordable, but less reliable, unlike a piston device. This factor is especially important, given the conditions of low winter temperatures.
4 - Control board, but it is only in inverter-type air conditioners. In other climatic devices, all electronics are located in the inner case, since external natural factors can adversely affect electronic components.
5 - Four-way valve it is installed only in models of reversible type air conditioners, that is, capable of not only cooling, but also working for space heating. This control unit is necessary to change the direction of freon movement when switching the device to heating mode. After that, in fact, the outdoor and indoor units change their functions - the outer one starts to work for cooling, and the inner one - for heating the air pumped through it.
6 - Fittings there are both on the indoor and on the outdoor unit, since copper pipes are connected to them, connecting the air conditioner department into one common refrigerant circulation system.
7 - Filter for cleaning the refrigerant is installed in front of the compressor and protects it from the ingress of small particles and copper chips, which often remain in the circuit during the installation of the air conditioner.
8 - Protective cover, covering the terminals of electrical cables and fittings. However, in some models, such a cover is provided only for electrical connections, while the fittings remain open.
Cleaning the outdoor unit of the air conditioner
Cleaning the external unit of the air conditioner can be done by hand only if it is installed in a private house, and you can safely work from a stepladder, or on the balcony of a high-rise building. Independent work at height without special equipment, an insurance system and experience is strictly prohibited!

The cleaning process is carried out in stages, in the following order:
- The first step is to turn off the device completely.
- Next, the front panel of the outdoor unit is dismantled. Having removed it, the owner will surely immediately see the whole volume upcoming work.
- First, all large debris found in the case is removed - it is he who slows down the operation of the air conditioner. Large debris is usually removed by hand, and no tools are required for this process.
- The next step is to remove dust layers from hard-to-reach places in the case. For this purpose, brushes of different widths and a hand-held vacuum cleaner are used.
- The fan blades can also be vacuum cleaned and, if necessary, wiped with a damp cloth. Wet cleaning must be done carefully so that water does not get on the electrical contacts. If it is necessary to use a large amount of water to wash the fan, then the electrical box should be covered with plastic wrap.
- The condenser has flat, smooth surfaces, so it is not difficult to clean it - this can be done with an ordinary damp cloth or sponge.
- Before reinstalling the front panel, it should also be thoroughly rinsed and dried.
- Do not touch the electrical unit of the device. Its repair and prevention should be carried out by specialists.
- Turning on the air conditioner can be done only after it has completely dried.
Learn how to do it, and also check out a few simple models with step-by-step instructions in a special article on our portal.
At the end of the topic, I would like to give some useful tips that will help you avoid making mistakes when operating and cleaning climate control devices.

- When purchasing an air conditioner, it is recommended to conclude an agreement for service maintenance device. During the warranty period, it can be carried out free of charge.
- Timely preventive maintenance will extend the period of trouble-free operation of the air conditioner and save you from many problems.
- It is recommended to entrust the first cleaning and disinfection of the air conditioner to specialists from the service department. At the same time, it is worthwhile to carefully monitor how they carry out preventive measures, in order to then use their experience when performing independent work.
- If the air conditioner began to malfunction, then you should not think that the malfunctions will go away by themselves. It is necessary to disconnect it from the mains and call the wizard for diagnostics and possible repairs.
- If you decide to clean it yourself, then you need to use special detergents and disinfectants. In addition, to clean the radiator of the indoor unit, it is convenient to use comb brushes, which are designed specifically for this purpose.
- Cleaning the air conditioner will be better if you use a steam cleaner for it. A jet of hot steam not only removes dirt, but also carries out preventive disinfection of structural parts.
- Assembly and inclusion in the network can only be done after complete drying of all parts of the air conditioner.
- Do not start the air conditioner when detergents are applied to its internal surfaces and the fan. It is extremely dangerous to do this, as water can get into the electrical unit of the device, which will cause a short circuit in the network. In addition, the dirt accumulated on the fan blades will scatter throughout the room, hitting the surfaces of the walls, ceiling, floor, furniture and other interior items.
- In order for the device to serve for a long time, it is necessary to follow all the rules for its operation specified by the manufacturer in the instructions.
So, from all of the above, it becomes clear that it is quite possible to perform work on cleaning climate equipment on your own, if you know the design of the device and the procedure for carrying out this process. If the owner can carry out preventive maintenance of the air conditioner on his own once and understand all the nuances, he will no longer have to call the master for this purpose, since the specialist will only be needed to solve more serious problems.
And, probably, an interested reader will find a video story useful in which an amateur craftsman shows how he cleans his air conditioner on his own.
Sooner or later, every owner of a home air conditioner has faced the problem of its pollution and unpleasant odor. Accordingly, before eliminating this problem, he had a question about how to disassemble the indoor unit of the air conditioner.
In order to get an answer to this question, it is worth understanding what the internal air conditioning system is.
How an air conditioner works and what it consists of
There are several types of air conditioners on the market. At first glance, it seems that they are all completely different. But it is not so. The principle of operation is similar for all of them. The most simple and budget options are window and mobile air conditioners. Both options consist of only one block.
A window air conditioner is mounted in a window opening, and a mobile air conditioner can work in any place where there is an open window or an ajar door to bring the hose out.
A more complex unit is a split system. Their installation requires certain knowledge and skills. It consists of two blocks: indoor and outdoor.
The composition of the outdoor unit:
- A compressor designed to maintain the flow of compressed gas - freon.
- A four-way valve responsible for the distribution of freon during cooling or heating.
- Fan.
- Fan condenser.
- Radiator. It cools and condenses freon gas
- Freon system filters, the task of which is to protect the ingress of foreign particles into the compressor
- A nipple connection to which copper pipes are connected for arching with the indoor unit
The composition of the indoor unit:
- Front Panel.
- Deep cleaning filter.
- Radiator.
- Evaporating and heating freon.
- Horizontal blinds.
- Display panel.
- Fine filter.
- Fan.
- Vertical blinds designed to adjust the direction of air flow masses.
- Tray for condensate. From there, condensate is discharged through the drain hose.
- Control fee.
- Plug connection.
How the air conditioner is disassembled
If, when you turn on the air conditioning system, the flow of cooling air carries with it a sour, stagnant moldy smell, then you should think about cleaning it. This requires flushing the outdoor and indoor units of the split system.
In order to solve this problem, you can use two methods: to attract a specialist, but this is a very expensive way, or to disassemble the indoor unit of the air conditioner with your own hands to perform cleaning work.
The latter method is more preferable, as it will save a significant amount of money, and the acquired useful experience will come in handy in the future.
Air conditioner disassembly guide
This method of disassembling a home air conditioner is universal, it is also suitable for disassembling the vast majority of brands that exist today.
In order to start disassembling the block, you should stock up on the necessary tools. For work you will need:
- Screwdrivers "minus" and "plus" of different diameters.
- Hexagon kit.
- Thin soldering iron.
- Special disinfectant for air conditioning systems.
- Long bristle brush
You need to know that in order to disassemble and clean the unit, you do not need to dismantle the unit from the wall, lower the freon and open the copper line.
First you need to disconnect the device from the power supply. After that, the protective filtration located in the block is removed. How to properly remove it, you can read in the instruction book that came with the air conditioner. The whole process is very detailed and understandable.
After that, the outer panel is removed from the block. And then two bolts are unscrewed, which are closed by fuses, and the frame stretches in its direction. It is fixed on the top side with two latches.
The entire panel that was on the top side will be covered in mold and dirt. It should be sent to the sink immediately.
With the use of a small force, a blade is pulled out of the grooves, which is responsible for the direction of air masses.
Then the lower area of \u200b\u200bthe indoor unit of the unit is removed from the valves - fasteners, where the drain hose and the wire supplying the air conditioner are disconnected.
If you have basic knowledge of electronics and radio engineering, then you can not write it down, but when reassembling, refer to the detailed connection diagram drawn on the back side of the block.
Then the mounting brackets are pressed out, and the housing of the electrical unit and transformer is removed. To dismantle the drain and outlet hose, you should very carefully and slowly squeeze out the three supporting fasteners. The opening, which serves to blow air masses out of the block, will also, like the bladed part, be covered with moldiness, from which such a nasty aroma spreads.
After that, you should unscrew the bearing bolts of the electronic engine of the split system and lift the radiator with great care, after which you can remove the motor support. Next, the blades and the engine located in the cell are removed. In order to eliminate the possibility of accidental fall of the radiator, it can be placed back.
Then it is necessary to remove the thermal lock located on the fixing bolt of the friction wheel with the rim of the electric motor. But you need to keep in mind that it will be difficult to disassemble these things on your own. In order to avoid accidental combustion of the rubber part that transmits energy, it is necessary to carefully heat the bolt head with a thin soldering iron, while trying to unscrew it during the soldering process. After the successful separation of the blades from the motor part, all moldy and dusty parts are placed in the sink.
In order to rinse thoroughly, remove all foreign odors and disinfect all removed elements, it is worth purchasing a special product for air conditioners. It does an excellent job of removing fungi, mustiness, mold and germs.
Starting to cleanse, you first need to shake the can. The agent is sprayed over the entire surface, which requires cleaning treatment. Wait twenty minutes. Then, with a long-haired brush, the contaminated places are scoured. And washed with water. The air conditioner is assembled in the reverse order.
How often does the air conditioner need to be cleaned?
Everyone understands that the time of full filtration is very dependent on the cleanliness of the premises. If the environment is polluted in the room, then the air conditioner will require frequent cleaning. In order to understand whether the air conditioner needs cleaning work, you can make an experiment. To do this, disassemble the device, if the filter is already completely clogged, then the next time, you need to do this a little earlier, and if the filter is still clean, then the procedure can be postponed until later. Also, on some modern models, you can determine the level of filter contamination using an indicator that provides information about the level of contamination at the present time.
In some residential areas, where perfect order reigns, daily wet cleaning is carried out - filters are changed only once a year. But this, of course, is an exceptional moment.
Ideally, the air conditioner requires cleaning every two weeks. Proper and regular care of the device will provide a pleasant and comfortable atmosphere in the house.
Conclusion
Thus, it is clear how to disassemble the indoor unit of the air conditioner, and there is absolutely nothing complicated about it.
It’s just worth stocking up with a little patience, free time and nothing to distract you.
Do-it-yourself disassembly will help save the family budget and give you a new experience that will be very useful in the future. Air conditioners need to be cleaned periodically and each time calling the master is not only expensive, but also not always convenient. As a rule, specialists have to wait and adjust to their time of arrival.
And the ability to make and understand technology brings moral satisfaction.
Sooner or later, any user of a household air conditioner faces an unpleasant problem - after turning on the split system, a cool breeze bursts out of the blow hole, filled with the sweet smell of stagnant mold.
This says only one thing - it's time to carry out maintenance on your split, or rather, wash it thoroughly.
Here you can act in two ways - call the master and part with a certain amount of money, or rely on your own strength and disassemble the air conditioner yourself.
This manual for disassembling the indoor unit of a split system (using the example Toshiba RAS-07EKH) will also help those who are faced with the problem of a breakdown of the air conditioner and are eager to fix it on their own.
And the last thing - the disassembly algorithm is typical, and is suitable for most modern split systems.
What you need
Yes, in general, a little. Several plus and minus screwdrivers of different diameters and (for some models) a set of hex sprockets.
If you have stocked up with such a simple arsenal, it's time to start!
And in order to finally dispel the last doubts, I clarify - in the process of all the operations described below, the indoor unit of the split system is not removed from the wall, the copper route is not disconnected, the freon is not drained.
Let's start cleaning the air conditioner!
Disassembly process
First things first, de-energize the air conditioner and remove the protective filters of the indoor unit. This process is detailed in the manual for any split.
Now you need to remove the front panel. We unscrew the two screws under the protective plugs,
and pull the frame towards you (two latches hold it on top).
The inside of the lid is covered in dust and mold, it belongs in the sink.
Now remove the airflow direction blade. To do this, you need to apply a little force and remove it from the grooves.
We get such a picture.
Now disconnect all electrical wiring, remembering to write down the location of the wires.
If you are too lazy to write, and your knowledge of radio engineering is worthy of respect, when reassembling, you can use the electrical circuit located on the inside of the front cover.
Be sure to disconnect the ground wires before removing the card from the slot.
Now we press the mounting brackets,
and take out the housing of the electronic unit together with the transformer.
Release the three support latches and carefully dismantle the drain together with the outlet hose.
Look at those awful brown spots.
The blow hole of the indoor unit, as well as the fan blades, are also covered with a disgusting coating that exudes a stench.
But let's continue
Loosen the motor support bolt
very carefully lift the radiator and remove the motor support,
after which we take out the blade together with the engine from the cell.
The radiator is carefully laid back so that it does not fall.
It is not easy to remove the thermal lock of the motor pulley mounting bolt.
In order not to burn the energy-transmitting rubber element, gently heat the head of the bolt with a thin soldering iron, periodically trying to unscrew it. I got it on the third try.
When the blade is separated from the motor, all dirty elements should go to the sink.
A bottle of Feri, a long-bristled brush and a powerful jet from the shower hose will help you get rid of annoying mold.
Reassemble in reverse order.
Conclusion
As you can see, the design of the indoor unit of a household split system is quite simple, if not primitive.
Therefore, if your hands grow from the right place, and the purse does not break from the abundance of excessive freaks, it is quite possible to service your favorite air conditioner on your own ...
