How to clean an air conditioner at home on your own: preparing climatic 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 air conditioner electrolux

For the 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 the 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 of a wall-mounted air conditioner in order to be able to do it with their own hands.

Design features of the indoor unit

Wall-mounted SPLIT systems from LG and others, including Daikin, Mitsubishi, Toshiba, Fujitsu, Ballu, Samsung and Hitachi, have a similar design of the internal module. Thanks to this, if you know the basic principles of disassembling the air conditioner, each owner may well cope with such a task on his own, only for this you should designate the main components and parts that make up such a block:

Wall mounted air conditioner standard design

Front (front) panel
Coarse filter
Fine filter
Fan
Evaporator
Horizontal blinds
Indicator 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 damage to internal components and modules, therefore, you should act carefully, without exerting excessive physical effort. Of the tools, several curly (cross-shaped) and straight (flat) screwdrivers of different sizes are required, as well as several hex stars.

Before disassembling, make sure that the air conditioner is switched 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 using clip 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 at the top and bottom, and in the second, use the appropriate tool. The next step is to remove the strainer (coarse cleaning) and plastic louvers from the indoor unit, which are simply removed from the corresponding grooves.

Strainer that needs cleaning

Next, you should carefully dismantle the drainage system of the indoor unit of the air conditioner, which is usually performed in the form of a tray. In some models, it can be made together 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.

Drainage 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. It 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 the control unit (the shaft is pulled out from below). Usually it is he who is chosen when doing work with his own hands, which requires less time and effort. Here the sequence of operations is as follows:

Unscrew the bolts / screws and release the radiator on the left side from 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 proceed carefully and slowly so as not to twist the head of the fastener element)

Carefully remove the shaft component from the body, and from underneath, taking care not to damage the blades (holding the screw with a screwdriver)

Important! In the reverse order of assembly (installation), the fan fastening screw must be in the position where it was originally, since otherwise there is a great risk of contact of the fan blades with the walls of the indoor unit.

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

We disconnect the wiring and electronic sensors from the control unit, unscrew the fastening clips (in some models, 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 completing 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 (active foam), clean water and steam (steam generator tool) for this. The condensate receiving tank 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 prolong their service.

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 internal components are very close to each other. This manual gives a sequence of actions that are performed regardless of the design features of the wall-mounted climatic technology.

Today we'll talk about how to disassemble an air conditioner, or rather the internal block of a wall-mounted split system. Any air conditioner requires regular maintenance, which includes disassembling and cleaning the units of the device. 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. Do not close the lid.

3. Remove the case of the internal device:

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

under the lid of the indoor unit (where the filters are) there can also be self-tapping screws (or clips) - we unscrew (or snap off) them. Carefully open the lower part of the case;

then our task is to "release" the clips from the top of the body. They are very rigid, and in order to "snap off" them 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 chips from the case, if any;

we open the blinds and remove the case (from the bottom towards ourselves or from the top towards ourselves, 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 “snaps into place” when reassembled. We recommend preparing a bag or container to drain any condensation (water) from the tray:

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

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

carefully remove the tray and at the same time disconnect the "tail" of the drainage hose (it can be fixed 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 specific device 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 part of the body must be collapsible):
unscrew and release the left side of the radiator from the housing 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, do not break the blades of the shaft and do not spoil the screw head. This screw is often very tight !;

we remove the shaft down from the body without damaging any parts (and our hands). It is usually very tightly fitted and requires experience to remove. 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 accurate "in place". Otherwise, the shaft can turn or touch the walls of the housing.

the most difficult situationwhen you have to remove the control unit and the shaft motor (we warn you that in this case it is highly desirable to contact a specialist):
- remove the control unit from the air conditioner housing. To do this, we disconnect all sensors and wires that fit to it. Then we release the clips and unscrew the self-tapping screws that secure it;
- unscrew the motor mounting cover (usually 4 screws). We unscrew all the self-tapping 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. Most likely, you will have to carefully bend the copper pipes that fit the radiator.

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

Thus, we have got a rather long, but rather detailed instruction on how to disassemble the air conditioner.

how to open the air conditioner to get to the fan bottom 2 screws found what needs to be done to open

Vadim Unscrew two or three screws under the horizontal blind.

Then gently push back the bottom of the case, making sure that the blinds go through the slot. There are three hooks on top, they will unhook themselves. After removing the case, carefully remove the thermo-resistor from the slot.
Then on the left side, unscrew one screw holding the drain pan, gently slide it off the hooks and let it hang from the drain hose.
The fan will be freely accessible.
Be careful when assembling. Don't break the hooks.

Service maintenance of the indoor unit of the air conditioner ...

Hello to all! At the request of my friends and my accomplices in general, I want to write a post about the service of air conditioners, because it is relevant already at the moment (I hope the moderators will be understanding)! The fact is that the consumer is often misled by offering them maintenance of the air conditioner ANNUALLY !!! It is not necessary to do this, because it all depends on the degree of pollution of the room itself, where the air conditioner is located!
How to understand that cleaning is already inevitable? Let's take a look at the process of cleaning the indoor unit, perhaps you yourself are able to perform this operation:
So before us is the usual internal block:

Below, so as not to mess up the repair, we glue the film onto ordinary masking tape:

We open the lid, remove the mesh filters and rinse them under running water (you can do this at any frequency, but at least once every 2 months!)

Now we completely remove the upper part of the case, together with the lid ...

We unfasten the tray (through it the condensate enters the street) ...

and then enjoy the gruesome sight! 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 DISASSEMBLING THE AIR CONDITIONER, you can see the degree of its contamination and make your own conclusion ... is it necessary to clean it?
Please note ... the fan impeller that we need to clean !!!

We remove the impeller (if possible), rinse with a stream of water and a brush, and clean the radiator with a steam generator ... VOIL:

Then we start assembling the indoor unit, in reverse order! But those same mesh filters ...

We fasten the lid, put the nets ...

We close the cover 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 ditch it stupidly!) And enjoy the coolness!

... I will tell you about the outdoor unit later! I would like to inform you that I have been dealing with air conditioning and ventilation since 2000 and I am ready to help with advice and business 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 run away) Have a good day everyone!

How to properly remove the air conditioner from the wall with your own hands

disassembled indoor unit. How to remove the air conditioner compressor and the outdoor unit itself with your own hands ... Remove the protective cover from the case; ...

Sooner or later, every home air conditioner owner faced the problem of pollution and unpleasant odors. Accordingly, before eliminating this problem, he had a question of how to disassemble the indoor unit of the air conditioner.

In order to get an answer to this question, it is worth figuring out what the internal air conditioner system is.

How does the air conditioner work and what does it consist 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. Window and mobile air conditioners are considered the simplest and most budgetary options. Both options consist of only one block.

The window air conditioner is mounted in the window opening, and the mobile air conditioner can work in any places where there is an open window or a slightly open 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.

Outdoor unit composition:

Compressor designed to maintain the flow of compressed gas - freon.
The four-way valve is responsible for the distribution of freon during cooling or heating.
Fan.
Blowing condenser.
Radiator. Freon gas is cooled and condensed in it.
Freon filters, the task of which is to protect the ingress of foreign particles into the compressor
Spigot connection to which the copper pipes for the roof with the indoor unit are connected

Indoor unit composition:

Front Panel.
Deep cleaning filter.
Radiator.
Evaporating and heating freon.
Horizontal blinds.
Indicator panel.
Fine filter.
Fan.
Vertical blinds designed to adjust the direction of air flow masses.
Condensate tray. From there, condensate is discharged through the drain hose.
Control board.
Fitting connection.

How the air conditioner is disassembled

If, when turning 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 indoor and outdoor units of the split system.

In order to solve this problem, you can use two ways: to attract a specialist, but this is a very costly 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, since it will save a significant amount of money, and the acquired useful experience will come in handy in the future.

Air Conditioner DIY 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 unit, you should stock up on the necessary tools. For work you will need:

Screwdrivers "minus" and "plus" of different diameters.
Hexagon set.
Slim soldering iron.
Special disinfectant for air conditioning systems.
Elongated 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, release freon and open the copper route.

First you need to disconnect the device from the power supply. After that, the protective filtration located in the block is removed. How to remove it correctly, you can read in the operation book that came with the air conditioner. The whole process is spelled out there in great detail and clearly.

After that, the external panel is removed from the unit. And then two bolts are unscrewed, which are closed by fuses, and the frame is pulled in its direction. It is fixed on the upper side with two latches.

The entire panel that was on the top side will be covered in mold and dirt. It must be sent to the sink immediately.

With the use of a small force, a blade is pulled out of the slots, which is responsible for the direction of the 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 don't have to write it down, but when reassembling it, refer to the detailed connection diagram drawn on the back side of the unit.

Further, the fastening brackets are squeezed out, and the body of the electrical unit and transformer is removed. To dismantle the drain and the outlet hose, you should very carefully and slowly squeeze out the three supporting fasteners. The opening, which serves to blow out air masses from the block, also, like the blade part, will be covered with mold, from which such a nasty aroma spreads.

After that, the supporting bolts of the electronic engine of the split system should be unscrewed and the radiator should be lifted with great care, after which the motor support can be removed. Next, the blades and the engine located in the cell are removed. In order to eliminate the possibility of accidental dropping of the radiator, it can be placed back.

Then it is necessary to remove the thermal lock located on the fastening bolt of the friction wheel with the rim of the electric motor. But you need to keep in mind that these things will be difficult to disassemble 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 using a thin soldering iron, while during the soldering process, you need to try to unscrew it. After a 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 agent for air conditioners. It does an excellent job of removing fungi, mustiness, mold and germs.

When starting to cleanse, you first need to shake the can. The product is sprayed over the entire surface that requires cleaning. Waiting for twenty minutes. Then the dirty areas are scrubbed with a long-bristled brush. And washed with water. The air conditioner is assembled in the reverse order.

How often the air conditioner needs cleaning

Everyone understands that the time for full filtration is very dependent on the cleanliness of the room. If the environment is polluted, 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, it is possible to determine the level of filter contamination using an indicator that gives information about the current level of contamination.

In some residential areas where perfect order reigns, daily wet cleaning is carried out - filters are changed only once a year. But this is, of course, an exceptional moment.

Ideally, the air conditioner should be cleaned every two weeks. Proper and regular maintenance 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.

You just need to stock up on a little patience, free time and so that nothing distracts.

Disassembling on your own will help to preserve the family budget and present a new experience that will be very useful in the future. Air conditioners need to be periodically cleaned and each time calling a master is not only costly, but also not always convenient. As a rule, specialists have to wait and adjust to their arrival time.

And the ability to make crafts and understand technology brings moral satisfaction.

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

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

First thing you need to do is prepare a set of screwdrivers of various sizes and workspace configurations. Also, do not forget to put boxes next to you for collecting fasteners, 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.

Disconnect the air conditioner
Remove the top cover of the unit
Remove the air filters

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

In addition to an unpleasant smell, clogging of the internal components of the air conditioner leads to faster wear of the power system of the device, increased power consumption and, what is most unpleasant, can cause a number of allergic respiratory diseases.

In fact, there are quite a few companies producing split systems today, but they all imply 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 the internal block of a split system for maintenance

Disconnect 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 pull out the plug from the outlet.
Remove the top cover of the unit ... Unscrew a few screws (two or three) covered with decorative plugs and remove the top cover of the indoor unit of the air conditioner. The lid, which is covered with dirt and mildew on the inside, should be washed in the bathroom using a brush and detergent.
Remove the air filters ... Remove the plastic coarse air filters. 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 ... Bending slightly, take out the special blinds from the grooves that direct the flow of cold air into the room. They, too, most likely need enhanced washing.
Disconnect the bottom cover of the indoor unit, the drain pipe and the power supply wire of the split system ... Gently squeeze out the three latches, and then disconnect the drain tray together with the outlet hose from the indoor unit of the split system.
Disconnect the wiring terminal blocks, remove the electronic control unit and the transformer ... To remove the control unit from the split system, gently squeeze the side mounts and then pull the device towards you. Do not forget to unscrew the ground wires before doing this.
Remove the fan motor. Unscrew the bolts securing the electric motor to the chassis, raise the evaporator and remove the engine together with the rotary fan outside.
Separate the motor from the fan ... First, you will need to gently warm up the head of the bolt with a soldering iron to unlock the thermal lock on the engine pulley. After removing the fan blades from the pulley, they can be thoroughly washed in the bath.

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

During the operation of the household split system, you can feel an unpleasant smell of rot along with the air flow from the device. It indicates the need for preventive cleaning of the unit. In addition to the repulsive amber, clogging of units 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 of the service center. But if you have been using the split system for a long time, you can cope with the work yourself, saving money. You just need to familiarize yourself with the disassembly procedure and preventive cleaning.

Indoor unit dimensions

Before installing the indoor unit of the air conditioner, you should inquire about its dimensions. This is especially important during repairs, because 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 dimensions. The block length usually varies from 700 to 800 mm. Somewhat less common are products up to 900 mm. Experts recommend taking into account an average length of 770 mm.

As for the height, it is usually 250-290 mm. The average value is 270 mm. The depth is of little 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 many contradictions on this issue. In some instructions the minimum distance is 50 mm, while in others it is 300 mm. The optimal value is equal to a figure from 60 to 150 mm.

Specialists usually install an air conditioner 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 pitch between them and the split system is usually 150 mm. This value can be increased up to 250 mm. The average distance from the block to the wall is 400 mm.

Indoor unit classification

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

wall split system;
ducted 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 a power within 7 kW allows you to cool up to 70 m 2 of the area. Such blocks are usually installed in the upper part of the wall, close to the window, since the structure provides for the presence of an outdoor block, 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 are wondering how to disassemble the indoor unit of the air conditioner, you can familiarize yourself with this information below. It is for such a device that the recommendations are given in the article.

In addition to household air conditioners, some manufacturers supply semi-industrial appliances to the market with a capacity of up to 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 false ceilings that completely hide them. The distribution of cooled air is provided by means of heat-insulated air ducts, which are located in the space between the ceiling. Such structures can cool several rooms at once. The power of the equipment reaches 25 kW, which makes it possible to provide cooling of a cottage or several rooms of an apartment. The main feature of duct systems is the ability to supply fresh air in the volume that is guaranteed by the functioning of full ventilation.

Cassette A / C units require a false ceiling during installation. Compared to duct designs, cassette units distribute cooled air through the bottom of the unit. It is covered with a decorative grille and usually has the following dimensions: 600 x 600 and 1200 x 600 mm.

Disassembling 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. Care should be taken to provide a collection box for the fasteners. You will need an electrical and functional diagram of the device. In some models, they are printed on the inside of the top cover.

To clean the internal elements you will need:

clean rags;
detergent;
vacuum cleaner.

The first step is to de-energize the air conditioner. This complies with electrical safety regulations. Remove the plug from the socket. The top cover of the unit is removable. The bolts are unscrewed, of which there can be two or three. Usually they are closed with decorative plugs. 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 detergent and a brush.

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. The brush will help with this.

The air flow guides must also be removed. The blinds are removed from the grooves. To facilitate the process, you need to bend them slightly. 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 detach the bottom cover. You will need to remove the drain tube and power cord. In the process, press out the three latches and disconnect the drain tray from the unit together with the outlet hose.

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 the transformer are removed. In order to take out the first one, it is necessary to squeeze the side mounts, 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, unscrew the bolts that are attached to the chassis. The evaporator rises and the motor is pulled outward 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. The assembly is carried out in reverse order.

Cleaning the outdoor unit

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

Independently or with the help of specialists

If the unit is located at an impressive height, then you can unscrew the protective grill and vacuum it, as well as wipe the inside of the dust. If not, you can seek the help of a professional who will remove the air conditioner using climbing equipment or a tower. Cleaning yourself can be done with the help of 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 "coat" of dirt is formed. This impedes the flow of air when blowing through 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 required even if you see black flakes flying out of the device. This suggests that the amount of dirt is so large that it does not hold on to the internal nodes. As a preventive measure, from time to time you can dismantle the fan and wash it with chemicals. But not all models make it easy to remove this part of the system.

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 sweetish smell of stagnant mold.

This says only one thing - it's time to service your split, or rather, wash it thoroughly.

Here you can do in two ways - call the master and part with a certain amount of money, or rely on your own strength and independently disassemble the air conditioner.

This manual for disassembling the indoor unit of the split system (for example Toshiba RAS-07EKH) will also help those who are faced with the problem of air conditioner breakdown and are eager to fix it on their own.

And the very last thing is a typical disassembly algorithm, and is suitable for most modern split systems.

What is needed

Yes, in general, a little. Several positive and negative screwdrivers of different diameters and (for some models) a set of hexagon sprockets.

If you have stocked up with such a simple arsenal, it's time to get started!

And in order to finally dispel the last doubts, I clarify - in the process of all the operations described below, the internal block of the split system is not removed from the wall, the copper track is not disconnected, the freon is not drained.

Let's start cleaning the air conditioner!

Disassembly process

First of all, turn off 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 bezel. We unscrew the two bolts under the protective plugs,

and pull the frame towards you (two latches hold it on top).

The inner side of the lid is covered with dust and mildew, it should be 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 the following picture.

Now disconnect all electrical wiring, remembering to write down the location of the wires.

If you are lazy to write, and your knowledge of radio engineering is worthy of respect, during reassembly 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 wring out the fastening brackets,

and take out the housing of the electronic unit along with the transformer.

Press out the three support catches and carefully remove the drain together with the outlet hose.

Look at those awful brown spots.

The blow-out opening 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

We unscrew the bolt of the electric motor support,

very carefully raise the radiator and remove the motor support,

after which we take out the blade together with the engine from the cell.

We carefully put the radiator back so that it does not fall.

Removing the thermal lock of the motor pulley mounting bolt is not easy.

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 did it on the third try.

When the blade is detached from the motor, all dirty items should go to the sink.

Get rid of annoying mold with a Feri bottle, long-bristled brush and powerful spray from the shower hose.

Reassemble in reverse order.

Output

As you can see, the design of the indoor unit of the household split system is quite simple, if not primitive.

Therefore, if your hands grow out of the right place, and your wallet does not burst from the abundance of excessive freak, it is quite possible to serve your favorite air conditioner on your own ...

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

Is it advisable to do such 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 a split system: the pros and cons of self-removing the air conditioner

As a rule, the main reason for removing an air conditioner is moving or replacing an obsolete device with a new one. When you change your place of residence or office, you don't want to leave the new owners with the split system bought at your own expense. 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 a speed and a guarantee that the device will not fail. The pricing policy depends on the capacity 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 a built-in suspended ceiling or cassette "Conder" increases by 5-15%.

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

Important! Nobody will be able to give a 100% guarantee for the uninterrupted operation of the air conditioner after its dismantling. The risk of dismantling / installing a split system in an unusable state is quite high.

If the above reasons are not enough and the desire to remove the device on your own is not lost, then you need to familiarize yourself with the air conditioner device 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 appropriate equipment and performs its own function.

The outdoor unit includes the following components:

heat exchanger - condenser;
a fan that drives air through a heat exchanger;
a compressor that builds up pressure;
dryer, connecting copper pipes and expansion valve;
electrical elements (power supply) and automation equipment.

The indoor unit of the air conditioner contains:

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

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

General operating principle of air conditioners: The compressor works with freon vapor. When turned on, 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 the heat from the house, heats up and transfers heat to the radiator. Thus, cyclical work occurs.

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

Dismantling a split system with your own hands: 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 an apartment air conditioner, you need to stock up on the following tools:

carob keys;
adjustable wrenches;
ratchet socket wrenches;
screwdriver PH2;
side cutters;
construction knife;
set of hexagons;
screwdriver;
pipe cutter;
gauge manifold.

Removal of refrigerant

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 of different sizes on the external block of the split system and unscrew the plugs with an adjustable wrench.
After starting the compressor with the hexagon, close the smaller valve. Immediately connect a manifold to the larger valve.
Monitor the pressure drop on the monometer. 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 removed 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 pipe carefully, applying slight efforts so as not to break the thread.
After disconnecting the freon line, close the valves with plugs - this will protect the external unit of the air conditioner from moisture and debris getting inside. In the absence of special plugs, you can use ordinary electrical tape.
Disconnect electrical connections.

Removing the outdoor and indoor unit of the air conditioner

Unscrew the external block of the split system from the horizontal brackets. Usually the outside of the air conditioner is screwed with four bolts M8, M6 or M10. After the bolts have been unscrewed, remove the outer casing and set it aside. Outside, on the facade of the building, only the freon outlet 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 detach the tubes. In fact, in order to correctly dismantle this part of the air conditioner, you must follow the recommended procedure:

The old freon highway remains on the facade of the building. For further installation of the split system, you will need nuts from the freon guide - 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 - only as it is installed on the brackets, that is, only upside down and feet down.

Features of dismantling air conditioners of different types

Above was the procedure for dismantling a wall 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 order of work is as follows:

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

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

Pressure control and pumping of freon.
Disconnecting the connecting lines and removing the outdoor unit.
Disconnection of communications of the indoor unit and its dismantling.

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

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

Internal fastening of the console (floor-to-ceiling) is carried out with the help of studs - this moment must be taken into account when disconnecting the unit from the wall or ceiling. Otherwise, the dismantling process is similar to removing 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 and pipes, it is advisable to mark their ends and additionally sketch the connection diagram. If reassembly is not carried out immediately after dismantling, then there is a risk of forgetting the order of their fastening.
Violation of the rules for dismantling can lead to pumping out of freon. The cost of pumping refrigerant and repairing a split system can be more expensive than calling a specialist for a qualified removal of the air conditioner.
The split system must be transported with extreme caution. The most sensitive and vulnerable part of the system is the vacuum pump. It can be expensive to repair or replace.
It is better to dismantle the indoor unit with 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 evaporator cover. In the absence of special tools, some get out of the situation using a Phillips screwdriver and pliers.
