How to clean the air conditioner at home on your own: preparing climate equipment for the summer season. How to disassemble the indoor unit of a split system with your own hands How to open the cover of an electrolux air conditioner

For efficient and safe operation of the air conditioner, regular cleaning of the internal elements of the system is required, and in addition to the external one, it is imperative to disassemble and clean indoor unit. Most often, in offices, apartments and private houses, wall-mounted SPLIT devices are installed, presented by different manufacturers and modifications. Given the demand and popularity of climate technology, many people will probably be interested in learning how to disassemble the indoor unit wall air conditioner to be able to do it by hand.

Design features of the indoor unit

Wall-mounted split systems by LG and others, which include Daikin, Mitsubishi, Toshiba, Fujitsu, Ballu, Samsung and Hitachi, have a similar design of the indoor module. Thanks to this, if you know basic principles disassembling the air conditioner, each owner can easily cope with such a task on his own, only for this it is necessary to designate the main components and parts that make up such a unit:

Standard design of wall mounted air conditioner

Front (front) panel
Coarse filter
Fine filter
Fan
Evaporator
Horizontal blinds
Display panel
Vertical blinds

You need to understand that proper disassembly consists in following a certain sequence of actions that allow you to gradually get to those elements that need to be cleaned. Only careful dismantling can eliminate the risk of breakage of internal components and modules, so you should act carefully, without applying excessive physical effort. Of the tools, several curly (phillips) and straight (flat) screwdrivers of various sizes are needed, as well as several hex stars.

Before dismantling, make sure that the air conditioner is turned off from the mains! This is very important to avoid electric shock.

Dismantling the indoor unit of the wall-mounted air conditioner

They begin to disassemble the air conditioner by removing the front plastic panel, which can be attached with clip-on elements (LG) or bolts (Toshiba), depending on the manufacturer. In the first case, you need to use a straight screwdriver and pry off the clips located above and below, and in the second, use the appropriate tool. The next step is to remove the strainer (coarse) and plastic blinds from the indoor unit, which are simply removed from the corresponding slots.

Strainer that needs to be cleaned

Next, you should carefully dismantle the drainage system of the indoor unit of the air conditioner, which is usually made in the form of a tray. In some models, it can be made integral with the body and removed only with it. Before removing it, prepare a container or container in advance to remove condensation formation. To detach the tray in LG models, you need to unscrew one bolt and snap off the clips located at the bottom.

Drain tray (on the right side detaches from the louver motor)

Fan/impeller removal options

Next, you need to remove the fan of the indoor unit of the SPLIT system, made in the form of a shaft. This will require very careful and responsible work, since it is important not to damage the internal components and components of the air conditioner.

Removing the strainer

There are two ways to pull out the shaft:

A simplified version, in which it is not necessary to perform operations with the electric motor and control unit (the shaft is pulled out from below). Usually it is he who is chosen when doing the work with his own hands, which requires less time and effort. Here the sequence of operations is as follows:

We unscrew the bolts / screws and release the radiator on the left side of the main main body of the SPLIT system
Gently loosen the fastener on the right, where you need to carefully unscrew the screw on the shaft itself (as a rule, it is tightened very tightly, so you need to act carefully and slowly so as not to twist the fastener head)

Carefully remove the shaft component from the housing, and from under the bottom, making sure not to damage the blades (holding the screw with a screwdriver)

Important! In the reverse assembly (mounting) sequence, the fan mounting screw must be in the position where it was originally, since otherwise there is a high risk of contact between the fan blades and the walls of the indoor unit.

A more complicated option is when the shaft is dismantled on the right side, for which the control unit and electric motor are removed. To perform the operation, proceed as follows:

We disconnect the wiring and electronic type sensors from the control unit, snap off the fastening clips (in some models we unscrew the fastening screws) and carefully remove the unit
We unscrew the fastening elements of the electric motor, disconnect the shaft from the casing
Very carefully and carefully, with slow movements, disconnect the shaft from the motor, and also bend the radiator tubes

When performing work, it is important to remember all the manipulations in order to assemble everything correctly after performing the service of the SPLIT installation.

What needs cleaning?

After performing these manipulations, you can start cleaning the internal components, and here it is imperative to remove dirt deposits from the rotor and evaporator, using antibacterial compounds for this ( active foam), clean water and steam (steam generator tool). The condensate receiving bath is also cleaned of dirt, after which all parts are thoroughly dried. In addition, it will not be superfluous to lubricate all moving parts with silicone grease, which will extend their service life.

To disassemble the indoor unit of the air conditioner, you need to be patient, act carefully and slowly. It is always important to remember that the SPLIT system has a complex structure, where all the internal components are very close to each other. This instruction gives a sequence of actions that are performed regardless of design features wall-mounted climate control equipment.

Today we’ll talk about how to disassemble the air conditioner, or rather the indoor unit of a wall-mounted split system. Any air conditioner requires regular maintenance, which includes disassembling and cleaning the device blocks. Cleaning the outdoor unit, as a rule, is not difficult, but disassembling the indoor unit is already more difficult.

Dismantling the indoor unit of the air conditioner

1. Turn off the air conditioner from the mains.

2. and remove the mesh filters. We do not close the lid.

3. Remove the housing of the internal device:

any block below the blinds has self-tapping screws (they are most often located under decorative plugs). We unscrew these screws;

under the cover of the indoor unit (where the filters) can also be self-tapping screws (or clips) - we unscrew (or snap off) them. Gently open a little lower part corps;

then our task is to “release” the clips on top of the case. They are very rigid, and in order to “snap them off” you need to carefully look at how they are attached (in most cases they “snap off” when you lift the bottom of the case towards you);

disconnect all the chips from the case, if any;

slightly open the blinds and remove the body (from below towards you or from above towards you, depending on the model).

4. The next task is to remove the drainage tray (in very rare models, it is not removed, but is made together with the entire body). It is important to consider how it is installed so that it “falls into place” during subsequent assembly. We recommend preparing a bag or container to drain possible condensate (water) from the tray:

usually on the left of the tray, you need to unscrew one screw, then release the clips from the bottom;

disconnect all the chips from the tray (or unscrew the blinds drive motor);

carefully remove the tray and at the same time disconnect the “tail” of the drainage hose (it can be secured with a latch or self-tapping screw).

5. The next task is to remove the shaft (fan). This is the most difficult and responsible operation. There may be two options depending on the device of a particular model:

more "easy situation" when the shaft is removed to the left without removing the motor and control unit (in this case, there must be a screw inside the shaft itself and the entire left side of the housing must be collapsible):
unscrew and release the left side of the radiator from the body of the indoor unit;

unscrew the screw on the right inside the shaft (not completely, but only a couple of turns). Here you need to act very carefully, not to break the shaft blades and not to spoil the screw head. This screw is often very "tight"!;

remove the shaft down from the housing without damaging any parts (and your hands). Usually it is very tightly installed and requires experience to remove it. We can hold the screw with a screwdriver and thus push and guide the shaft.

When installing the shaft back, the screw must be very accurately screwed into place. Otherwise, the shaft may rotate or touch the walls of the housing.

the most difficult situation when you have to remove the control unit and the shaft motor (we warn you that in this case it is highly advisable to contact specialists):
- remove the control unit from the air conditioner housing. To do this, disconnect all the sensors and wires that fit it. Then we release the clips and unscrew the screws that secure it;
- unscrew the motor mount casing (usually 4 self-tapping screws). We unscrew all the screws that will help free the casing and shaft;
- we carefully study how to disconnect the shaft from the motor and remove it from the housing. You will most likely have to bend copper tubes that fit the radiator.

To assemble the air conditioner, we perform the considered operations in reverse order.

Thus, we got a rather long, but enough detailed instructions how to disassemble the air conditioner.

Vadim Unscrew two or three screws under the horizontal blinds.

Then gently move the bottom of the body. Try to let the blinds pass through the slot. There are three hooks on the top, they will unhook themselves. After removing the housing, carefully remove the thermal resistor from the slot.
Then, on the left side, unscrew one screw holding the drain pan, carefully slide it off the hooks and let it hang on the drain hose.
Access to the fan will be free.
Be careful when assembling. Don't break the hooks.

Service of the internal block of the 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 on this moment(I hope the moderators will react with 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 ...

So we got to the main point that I wanted to tell you about! WITHOUT DISASSEMBLY OF THE AIR CONDITIONER, you can see the degree of its contamination and independently draw a conclusion ... but is it necessary to clean it?
Pay attention ... The fan impeller, which we need to clean!!!

We remove the impeller (if possible), wash it with a jet of water and a brush, and clean the radiator with a steam generator ... Voilà:

Then proceed to the assembly of the indoor unit, in reverse order! But those same mesh filters ...

We fasten the lid, put the nets ...

Close the lid of the indoor unit...

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!

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 himself outdoor unit with their own hands ... Remove the protective cover from the case; ...

Sooner or later, every owner of a home air conditioner has faced the problem of its pollution and bad smell. 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 is internal system conditioner.

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 simplest and budget options window and mobile air conditioners are considered. 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.

More complex aggregate 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 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 necessary tools. For work you will need:

Screwdrivers "minus" and "plus" different diameter.
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 one drawn on the back side of the block, to detailed diagram connections.

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 contamination of the filter, using an indicator that provides information about the level of contamination at the present time.

In some living quarters, where perfect order reigns, daily cleaning is carried out. wet cleaning– 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.

Just worth stocking up a little patience, free time and nothing to distract.

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.

If you notice that the cold air coming out of the split system has an unpleasant sweet smell of rot, this means that the unit urgently needs preventive cleaning.

Of course, you can entrust this procedure to a service worker, especially if the air conditioner is still under warranty service. But if you have been using a split system for a long time and do not intend to pay big money for something that you can handle on your own, then you should know the procedure for disassembling the air conditioner for its preventive cleaning.

First of all, you should prepare a set of screwdrivers of various sizes and workspace configurations. Also, do not forget to put the boxes for collecting fasteners next to you, as well as the functional and electrical diagram of the air conditioner (in some models, the electrical diagram is printed on the inside of the top cover of the unit). To clean the internal elements of the split system, you will need a vacuum cleaner, detergents and clean rags.

If you notice that cold air coming out of the split system has an unpleasant sweet smell of rot - this means that the unit urgently needs preventive cleaning

In addition to an unpleasant odor, clogging of the internal components of the air conditioner leads to faster wear of the power system of the device, increased power consumption and, most unpleasantly, can cause whole line allergic respiratory diseases.

Of course, you can entrust this procedure to a service worker, especially if the air conditioner is still under warranty. But if you have been using a split system for a long time and do not intend to pay big money for something that you can handle on your own, then you should know the procedure for disassembling the air conditioner for its preventive cleaning.

In fact, there are quite a lot of companies producing split systems today, but they all involve a more or less unified system for building indoor units. Therefore, even if you encounter some design differences, the basic disassembly technique will remain the same.

How to disassemble for maintenance the indoor unit of a split system

Turn off the power to the air conditioner . This is the first thing to do in order to comply with electrical safety rules. Do not turn off the air conditioner with the remote control button, but simply remove the plug from the socket.
Remove the top cover of the block . Remove a few bolts (two or three) covered with decorative caps and remove the top cover of the indoor unit of the air conditioner. The cover, covered with a layer of dirt and mold from the inside, should be washed in the bathroom using a brush and detergent.
Remove air filters . Delete plastic filters rough air purification. They can be mounted both on the block cover and inside it. We also wash the filters under a strong stream of water, helping ourselves with a brush.
Remove the airflow guides . Slightly bending, remove from the grooves special blinds that direct the flow of cold air into the room. They, too, most likely need enhanced washing.
Detach the bottom cover of the indoor unit, drainage tube and a split system power cable . Gently wring out the three latches, and then disconnect the drain bath together with the outlet hose from the indoor unit of the split system.
Disconnect terminal blocks electrical wiring, remove the electronic control unit and transformer . To remove the control unit from the split system, carefully wring out side mounts, then pull the device towards you. Do not forget to unscrew the ground wires before doing this.
Remove the fan motor. We unscrew the bolts securing the electric motor to the chassis, lift the evaporator and remove the engine together with the rotary fan.
Separate the motor from the fan . First, you will have to gently heat the bolt head with a soldering iron to unlock the thermal lock on the motor pulley. After the fan blades are removed from the pulley, they can be thoroughly washed in the tub.

The assembly of the indoor unit of the split system should be done in the reverse order.

During the operation of a household split system, you can feel bad smell rot along with air currents from the device. It indicates the need for preventive cleaning of the unit. In addition to repulsive amber, clogging of nodes can cause rapid wear of the power unit, increased power consumption and the occurrence of allergic reactions in humans.

This procedure can be entrusted to an employee service center. But if you have been using a split system for a long time, you can handle the work yourself, saving money. It is only necessary to familiarize yourself with the procedure for disassembly and preventive cleaning.

Indoor unit dimensions

Before installing the indoor unit of the air conditioner, you should take an interest in its dimensions. This is especially important when renovating modern technologies quite often provide for the installation of suspended ceiling systems, which can affect the height of the ceiling, as well as the parameters of the described device.

On sale you can find non-standard models that have unique sizes. The length of the block usually varies from 700 to 800 mm. Products up to 900 mm are somewhat less common. Experts recommend taking into account average length at 770 mm.

As for the height, it is usually equal to 250-290 mm. The average value is 270 mm. Depth is not of great interest to consumers, but it reaches 240 mm. The minimum value is equivalent to 170 mm. From this we can conclude that the average dimensions of the indoor unit of the air conditioner are 770 x 270 mm.

Knowing these parameters allows you to determine at what distance from the ceiling and walls to hang equipment. There are a lot of controversies on this issue. In some instructions, the minimum distance is 50 mm, while in others it goes up to 300 mm. The optimal value is equal to a figure from 60 to 150 mm.

Specialists usually install air conditioning with a distance of 100 mm. Before installing the indoor unit of the air conditioner, it is important to consider whether there will be curtains in the room. The step between them and the split system is usually 150 mm. You can increase this value up to 250 mm. The average distance from the block to the wall is 400 mm.

Classification of indoor units

In order to carry out disassembly, it is necessary to determine the type of the indoor unit of the air conditioner, which can be represented:

wall split system;
channel air conditioner;
cassette device.

The most common are wall models, which are more affordable and are sometimes also called household. Their installation can be carried out in a room for any purpose, and the power within 7 kW allows you to cool up to 70 m2 of area. Such blocks are usually installed in the upper part of the wall, not far from the window, since the design provides for the presence of an outdoor unit, and the nodes must be interconnected.

Wall-mounted air conditioners are not able to supply fresh air to the premises, as this requires a separate ventilation system. If you wondered how to disassemble the indoor unit of the air conditioner, you can read this information below. It is for such a device that the recommendations in the article are given.

In addition to household air conditioners, some manufacturers supply semi-industrial devices to the market, the power of which reaches 10 kW. Outwardly, they look like traditional split systems, but in terms of parameters they are semi-industrial equipment.

Ducted air conditioners are installed with suspended ceilings that hide them completely. The distribution of cooled air is provided by heat-insulated air ducts, which are located in the interceiling space. Such structures can cool several rooms at once. The power of the equipment reaches 25 kW, which makes it possible to provide cooling for a cottage or several rooms of an apartment. The main feature of channel systems is the possibility of supplying fresh air in the volume that is guaranteed by the functioning of full ventilation.

Cassette air conditioners require a false ceiling during installation. When compared to duct designs, cassettes distribute cooled air through the bottom of the unit. She closes decorative grille and usually has the following dimensions: 600 x 600 and 1200 x 600 mm.

Dismantling and cleaning the air conditioner

To clean the indoor unit of the air conditioner, it is necessary to disassemble it. For this, screwdrivers of various configurations and sizes are prepared. You should take care of the presence of a box for collecting fasteners. Requires electrical and functional diagram device. In some models, they are printed on the inside of the top cover.

To clean the internal elements you will need:

clean rag;
detergent;
vacuum cleaner.

The first step is to de-energize the air conditioner. This is in accordance with electrical safety regulations. Remove the plug from the socket. The top cover of the block is removed. Bolts are unscrewed, which can be two or three. Usually they are closed with decorative caps. The top cover of the indoor unit is removed. If it is covered with a layer of mold and dirt, it should be washed in the bathroom with detergents and brushes.

When disassembling the indoor unit of the air conditioner, you will need to remove the air filters. They are made of plastic and are designed for rough air purification. Sometimes they are fixed on the lid or inside the air conditioner. The filters are washed under an intense stream of water. A brush will help with this.

The airflow guides should also be removed. Blinds are removed from the grooves. To facilitate the process, you need to slightly bend them. These elements direct the flow of cold air into the room and also need enhanced flushing.

Removing the bottom cover

The next step is to remove the bottom cover. You will need to remove the drain tube and power cord. In the process of this, three latches should be pressed and the drain tray together with the outlet hose should be disconnected from the unit.

Removing terminal blocks

The indoor unit of the air conditioner has terminal blocks. They are disconnected during disassembly, and then the electronic control unit and transformer are removed. In order to remove the first one, it is necessary to wring out the side fasteners, and then pull the device towards you. Before this, the ground wires are unscrewed.

Removing the fan motor

The fan motor can now be removed. To do this, the bolts are unscrewed, which are strengthened to the chassis. The evaporator is raised and the engine is pulled out along with the rotary fan. The motor must be separated from the fan, but first you have to warm up the bolt head with a soldering iron. This will unlock the thermal lock on the motor pulley. Once the fan blades can be removed, they must be washed. Assembly is carried out in the reverse order.

Cleaning the outdoor unit

Outdoor and indoor units of air conditioners are equally in need of maintenance. The frequency for the first is twice a year, which is true even with intensive use. A vacuum cleaner is required for this, but the device must be powerful enough to extract dust from external filters and heat exchangers.

On your own or with the help of specialists

If the unit is located at an impressive height, then you can unscrew the protective grille and vacuum it, as well as wipe the insides from dust. Otherwise, you can seek help from professionals who will remove the air conditioner using climbing equipment or a tower. Cleaning yourself can be done using compact senders, but the air conditioning system will have to be de-energized and turned on only 30 minutes after the end of the service.

Finally

During the operation of the split system, dust settles on the fan impeller, where a “fur coat” of dirt is formed. This prevents the passage of air flow when blowing the evaporator. The latter freezes over, and the user does not receive normal cold and intense air flow.

Cleaning the fan of the indoor unit of the air conditioner is also required when you see black flakes flying out of the appliance. This suggests that the amount of dirt is so large that it does not hold onto the internal nodes. As a preventive measure, from time to time you can dismantle the fan and wash it. chemicals. But not all models make it easy to extract this part of the system.

Sooner or later any user domestic air conditioner faces an unpleasant problem - after turning on the split system, a cool breeze breaks 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 the 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, copper track does not disconnect, freon does not merge.

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, you can use electric circuit located on inside 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 ...

It is more difficult to dismantle a split system consisting of an outdoor and indoor unit than a monoblock air conditioner. The main nuance lies in the closed refrigerant circulation circuit, which must be depressurized when removed.

Is it advisable to do this work on your own or is it better to entrust it to professionals? What is the technology for dismantling the air conditioner? The answers to these questions are described in the article.

Dismantling the split system: the pros and cons of self-removal of the air conditioner

As a rule, the main reason for removing the air conditioner is moving or replacing an obsolete device with a new one. When changing your place of residence or office, you do not want to leave the split system purchased for your own money to the new owners. In this case, you can invite a team of specialists to dismantle the air conditioner or try to do this work yourself.

Professional installers will dismantle air conditioners (split systems) in 15 minutes, but you will have to pay for such speed and a guarantee that the device will not fail. Price policy depends on the power of the equipment: the removal of an apartment air conditioner will cost 2500-4000 rubles, a large office split system - up to 10000 rubles. The cost of dismantling the built-in suspended ceiling or cassette "conder" increases by 5-15%.

In principle, a person who is familiar with the technical topic and shared device air conditioner, it will be more or less clear how to unscrew the fittings, pump out the refrigerant, disconnect communications, remove the split system units and pack the elements in boxes. However, not all so simple. There are some risks to be aware of:

Important! No one can give a 100% guarantee for the safety of the uninterrupted operation of the air conditioner after its dismantling. The risk of dismantling / installing a split system in an unusable condition is quite high.

If the above arguments are not enough and the desire to remove the device on your own has not disappeared, then you need to familiarize yourself with the device of the air conditioner and understand the technology of its dismantling.

Air conditioner device

50% of the success of its removal depends on understanding the operation of the split system. A modern split system consists of outdoor and indoor units, each of which contains a set of relevant equipment and performs its function.

The outdoor unit includes the following components:

heat exchanger - condenser;
a fan that drives air through the heat exchanger;
a compressor that pressurizes;
dryer, connecting copper pipes and expansion valve;
electrical elements (powered from the mains) and automation equipment.

The indoor unit of the air conditioner contains:

heat exchanger - evaporator with fan;
shutters directing the air flow;
filter elements;
container for collecting condensate.

The blocks are interconnected by two lines for the coolant. By big pipe The refrigerant moves in the form of a gas, and through a pipe with a smaller diameter - in a liquid state.

The general principle of operation of air conditioners: The compressor works with freon vapor. When turned on, the refrigerant vapors heat up and enter the outdoor unit, where they transfer heat to the radiator. Then the refrigerant returns to the indoor unit, absorbs heat from the house, heats up and transfers heat to the radiator. Thus, there is a cyclical work.

Important! The greatest danger of deformation during dismantling is exposed to Vacuum pump compressor. Even minor damage to the pump reduces the performance of the split system - dust, scratches, foreign objects and dirt can cause the performance of the air conditioner to decrease.

Do-it-yourself dismantling of a split system: a sequence of actions

Required Tools

When servicing the split system and dismantling it, it is important to follow the basic safety rules: work with an assistant and use safety equipment.

To remove the apartment air conditioner, you need to stock up on the following tools:

open-end wrenches;
wrenches;
socket wrenches with ratchet;
screwdriver PH2;
side cutters;
construction knife;
a set of hexagons;
screwdriver;
pipe cutter;
manometric manifold.

Refrigerant removal

Before removing the air conditioner, it is necessary to “overtake” the refrigerant:

Turn on the air conditioner in cooling mode, set the lowest temperature mode on the remote control.
Find two valves on the outdoor unit of the split system different sizes and wrench unscrew the plugs.
After starting the compressor with a hexagon, close the smaller valve. Connect the gauge manifold directly to the larger valve.
Monitor the pressure drop on the pressure gauge. As soon as the arrow drops below zero, tighten the large valve.

After completing these steps, turn off the air conditioner - now all the refrigerant is discharged to the outdoor unit. The next step is to disconnect the wire from the outdoor unit.

Disconnecting communications

Sequencing:

Unscrew the smaller tube. As a rule, this process does not cause any difficulties.
Unscrew the large tube carefully, applying little effort so as not to strip the thread.
After turning off the freon pipeline, close the valves with plugs - this will save outdoor unit air conditioner from moisture and debris getting inside. In the absence of special plugs, you can use ordinary electrical tape.
Disconnect electrical communications.

Removing the outdoor and indoor unit of the air conditioner

Unscrew the outdoor unit of the split system from the horizontal brackets. Usually the outer part of the air conditioner is screwed with four bolts M8, M6 or M10. After the bolts are loosened, remove the outer casing and set aside. Outside, on the facade of the building, only a freon drain should remain, which has not yet been removed.

The next step is to dismantle the indoor unit of the split system. To an inexperienced specialist, the removal process from the side will seem simple: disconnect from the wall and unfasten the tubes. In fact, in order to correctly dismantle this part of the air conditioner, you must follow the recommended procedure:

The old freon line remained on the facade of the building. For further installation of the split system, you will need nuts from the freon pipe - they must be unscrewed from the pipe.

Important! During transportation, the inside of the air conditioner can be positioned in any position, and the outdoor unit can only be positioned as it is installed on the brackets, that is, only upside down and down with legs.

Features of dismantling air conditioners of various types

Above was the procedure for dismantling a wall-mounted split system with your own hands - in fact, a household air conditioner. The situation is more complicated with the removal of the channel split system - the device is very heavy, and its dismantling requires disconnecting the air ducts from the blocks.

The work order is as follows:

Remove supply and exhaust adapters with grille.
Disconnect the air ducts from the indoor unit - unscrew the screws or remove the clamps (depending on the model of the air conditioner).
Inject freon into the outdoor unit.
Continue the removal according to the described scheme for dismantling the wall-mounted device.

The column split system is removed in the same sequence as the wall split system according to the scheme:

Freon pressure control and pumping.
Disconnecting connecting lines and removing the outdoor unit.
Disconnecting the communications of the indoor unit and dismantling it.

The indoor column unit does not have a mounting plate or fastening studs (like a console, cassette), so the dismantling process is somewhat simplified.

The removal of the cassette split system occurs according to the channel scheme. The dismantling of the indoor module begins with loosening the fastening nuts and sequentially disconnecting the communications. The difference from the channel split system is that the cassette split system does not have air ducts.

The internal fastening of the console (floor-ceiling) occurs with the help of studs - this point must be taken into account when disconnecting the unit from the wall or ceiling. Otherwise, the dismantling process is similar to the removal of a wall-mounted air conditioner.

Important! It is impossible to dismantle the split system in rainy or snowy weather. Moisture trapped inside will damage the compressor.

When disconnecting wires, tubes, it is desirable to mark their ends and additionally draw a connection diagram. If reassembly is not performed immediately after dismantling, then there is a risk of forgetting the order of their fastening.
Violation of the dismantling rules can lead to pumping out freon. The cost of pumping refrigerant and repairing a split system can be more expensive than calling a specialist for a qualified removal of an air conditioner.
Transportation of the split system must be carried out with extreme caution. The most susceptible and vulnerable part of the system is the vacuum pump. It will be expensive to repair or replace.
Dismantling the indoor unit is best done by three people. Two hold, one unscrews communications, etc.
When removing the indoor unit, it is most difficult to get to the latches. Often you have to remove the cover of the evaporator. For lack of special tools, some get out of position using a Phillips screwdriver and pliers.
