How to disassemble an electrolux split system. How to remove the front cover of the air conditioner. How to disassemble a wall-mounted air conditioner. Disassembly in winter
Sooner or later, any user of a household air conditioner is faced with an unpleasant problem - after turning on the split system, a cool breeze bursts out of the blower hole, filled with the sweetish smell of stagnant mold.
This only means one thing - it’s time to carry out maintenance on your split, or rather, wash it thoroughly.
Here you can do two things - call a specialist and part with a certain amount of money, or rely on own strength and disassemble the air conditioner yourself.
This guide is for disassembling the indoor unit of a split system (using the example Toshiba RAS-07EKH) will also help those who are faced with the problem of an air conditioner breakdown and want to fix it on their own.
And the last thing - the disassembly algorithm is standard, and is suitable for most modern split systems.
What you will need
Yes, in general, a little. Several positive and negative screwdrivers different diameters and (for some models) a set of hexagonal sprockets.
If you have stocked up on such a simple arsenal, it’s time to get started!
And in order to completely dispel the last doubts, I would like to clarify that during all the operations described below, the internal unit of the split system is not removed from the wall, the copper line is not disconnected, and the freon is not drained.
Let's start cleaning the air conditioner!
Disassembly process
First of all, turn off the power to the air conditioner and remove the protective filters of the indoor unit. This process is described in detail in the manual for any split.
Now you need to remove the front panel. Unscrew the two bolts 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 air flow direction blade. To do this, you need to apply a little force and remove it from the grooves.
We get this 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 electrical diagram, located on inside front cover.
Be sure to disconnect the ground wires before removing the card from the socket.
Now we press out the fastening brackets,
and remove the electronic unit housing along with the transformer.
Press out the three support latches and carefully remove the drain along with the outlet hose.
Look at those ugly brown spots.
The exhaust hole of the indoor unit, as well as the fan blades, are also covered with a disgusting coating that emits a stench.
But let's continue
Unscrew the motor support bolt,
very carefully lift the radiator and remove the motor mount,
after which we remove the blade along 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.
To avoid burning the energy-transmitting rubber element, use a thin soldering iron to carefully heat the head of the bolt, periodically trying to unscrew it. I succeeded on the third try.
When the blade is separated from the motor, all dirty elements should go to the wash.
A bottle of Feri, a long bristle brush and a powerful jet of 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 your wallet is not bursting with an abundance of unnecessary frills, it is quite possible to service your favorite air conditioner on your own...
During operation of a household split system, you may feel bad smell rotted along with air flows from the device. It indicates the need for preventative cleaning of the unit. In addition to the repulsive odor, clogged components can cause rapid wear of the power unit, increased energy consumption and the occurrence of allergic reactions in humans.
You can entrust this procedure to an employee service center. But if you have been using a split system for quite some time, you can handle 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 involve the installation of suspended ceiling systems, which can affect the height of the ceiling, as well as the parameters of the device being described.
On sale you can find non-standard models that have unique sizes. The block length usually varies from 700 to 800 mm. Products up to 900 mm are somewhat less common. 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 not of much 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 air conditioner unit 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 contradictions on this issue. Some instructions set the minimum distance to 50mm, while others go as high as 300mm. The optimal value is between 60 and 150 mm.
Experts usually install an air conditioner at a distance of 100 mm. Before installing the indoor air conditioner unit, 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. This value can be increased to 250 mm. The average distance from the block to the wall is 400 mm.
Classification of indoor units
In order to disassemble, it is necessary to determine the type of indoor unit of the air conditioner, which can be represented by:
- wall split system;
- duct air conditioner;
- cassette device.
The most common are wall models, which are more affordable and are sometimes also called household ones. Their installation can be carried out in a room for any purpose, and the power within 7 kW allows cooling up to 70 m 2 of area. Such blocks are usually installed at the top of the wall, near 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 capable of supplying fresh air to the premises, since this requires a separate ventilation system. If you are wondering how to disassemble the indoor unit of an air conditioner, you can find this information below. It is for such a device that recommendations are given in the article.
In addition to household air conditioners, some manufacturers supply the market with semi-industrial appliances whose power reaches 10 kW. Outwardly, they resemble traditional split systems, but in terms of parameters they are semi-industrial equipment.
Duct air conditioners are installed with suspended ceilings that hide them completely. Distribution of cooled air is ensured using thermally insulated air ducts, which are located in the inter-ceiling 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 in an apartment. The main feature of channel systems is the ability to supply fresh air to the extent guaranteed by the functioning of full ventilation.
Cassette air conditioners require a suspended ceiling during installation. When compared to ducted designs, cassette designs 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 purpose, screwdrivers of different configurations and sizes are prepared. Make sure you have a box for collecting fasteners. You will need electrical and functional diagram device. In some models they are applied to the inside of the top cover.
For cleaning internal elements you will need:
- clean rags;
- detergent;
- vacuum cleaner.
The first step is to turn off the power to the air conditioner. This complies with electrical safety regulations. The plug must be removed from the socket. The top cover of the unit is removed. The bolts are unscrewed, of which there may be two or three. They usually close 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 using detergents and a brush.
When disassembling the indoor unit of the air conditioner, you will need to remove 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 air flow guides should also be removed. The blinds are removed from the grooves. To make the process easier, you need to bend them slightly. These elements direct the flow of cold air into the room and also require intensive washing.
Removing the bottom cover
The next step is to detach the bottom cover. You will need to remove the drain tube and power cord. During this process, you should release the three latches and disconnect the drain pan along with the outlet hose from the block.
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, you need to squeeze side mounts, and then pull the device towards you. Before this, the grounding wires are unscrewed.
Removing the fan motor
Now you can remove the fan motor. To do this, the bolts that are secured to the chassis are unscrewed. The evaporator is lifted and the motor is removed out along with the rotary fan. The motor must be separated from the fan, but first you will 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 need to be washed. Assembly is carried out in reverse order.
Cleaning the outdoor unit
External and internal air conditioner units require equal maintenance. 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 remove dust from external filters and heat exchange radiators.
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 the help of professionals who will remove the air conditioner using climbing equipment or a tower. You can clean it yourself 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.
In conclusion
During operation of the split system, dust settles on the fan impeller, where a “coat” of dirt forms. This prevents air from flowing 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 also required when you see black flakes flying out of the device. This indicates that the amount of dirt is so large that it is not retained on the internal components. As a preventive measure, from time to time you can dismantle the fan and wash it chemicals. But not all models allow you to easily remove this part of the system.
How to disassemble the air conditioner yourself to eliminate the unpleasant odor from the split system? To parse wall mounted air conditioner do it yourself, you first need to familiarize yourself with some of the features of household air conditioners.
How to disassemble an air conditioner
One day, any user of a wall-mounted, household air conditioner is faced with the following unpleasant problem: when the split system is turned on, a stream of cool air bursts out of its blowout hole, filled with a slightly sweetish smell of already stagnant mold. This means that it’s time for you to carry out maintenance on your air conditioner, that is, wash it thoroughly, and inside the system. There are two ways to solve this problem: the first is to call a specialist (however, this method is expensive), the second is to independently disassemble the split system and then clean it on your own.
We suggest that you do everything yourself, because this way you will be able to save a certain amount of money, and besides, this skill may come in handy in the future. We present to you a guide to disassembling an indoor air conditioner unit, which will help you solve the problem of unpleasant odor from the split system. The considered algorithm for disassembling an air conditioner is typical, so it is suitable for many brands of modern air conditioning devices. So, to disassemble the air conditioner yourself, you will need several negative and positive screwdrivers of various diameters, as well as a set of hexagonal stars (not for all models of split systems). If you already have such a simple arsenal, then you can start disassembling the indoor unit. Please note that when cleaning the air conditioner, you do not have to remove the device from the wall, disconnect the copper line and drain the freon.
First of all, turn off the power to the air conditioner, and then remove the protective filters from the internal unit of the device. This process is described in detail in the standard maintenance manual for your split system. Next, remove its front panel from the block; to do this, unscrew the two bolts that are covered with protective plugs, then pull the frame towards you (it is held on top by two latches). The inside of the lid will be covered with mold and dust, so immediately send it to the sink. Next, remove the blade that directs the air flow; to do this, apply a little physical force and pull it out of the grooves. Then remove the lower part of the indoor air conditioner unit from the latches, and then disconnect the split system drain hose and its power cable.
Next you need to disconnect all the electrical wiring, and it is better to write down how the wires are located. If you are too lazy to write down, and besides, you can boast of your tremendous knowledge in radio engineering, then when you put the air conditioner back together, you can use its electrical circuit, which is located on the inside of the front cover of the indoor unit.
Next, press out the fastening brackets, and then remove the electronic unit housing and the transformer. Then you need to press back the three support latches and carefully remove the drain and outlet hose. The hole for blowing air from the indoor unit, as well as the blades of the built-in fan, will be covered with a strong coating, which emits an unpleasant odor. After this, unscrew the support bolts of the air conditioner motor, carefully lift the radiator, and remove the motor support. Next, remove the blades, as well as the engine from the cell, and you can carefully put the radiator back so that it does not suddenly fall.
Next, remove the thermal lock, which is located on the electric motor pulley mounting bolt. Please note that this is not easy to do. To prevent the rubber element that transmits energy from accidentally burning out, you need to carefully heat the head of the bolt using a thin soldering iron, and periodically try to unscrew it. When you manage to separate the blade from the motor, send all contaminated elements of the system to the wash. To wash all the parts you will need a bottle detergent, a brush with fairly long bristles, and a lot of water. Reassembling the air conditioner is carried out in the reverse order.
You can see for yourself that the design of a wall-mounted split system indoor unit is not very complicated. Therefore, in order not to waste extra funds, you can clean the device yourself, and you now know how to disassemble the air conditioner yourself.
Sooner or later, every owner home air conditioner I was faced with the problem of its contamination and unpleasant odor. Accordingly, before fixing this problem, he had a question about how to disassemble the indoor unit of the air conditioner.
In order to get an answer to this question, it is worth understanding what the internal air conditioning system is.
How does an 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 this is not entirely true. The principle of operation is similar for all of them. The simplest and most cost-effective options are window and mobile air conditioners. Both options consist of only one block.
The window air conditioner is mounted in the window opening, and mobile air conditioner can work in any place where there is an open window or a slightly open door to lead the hose outside.
A more complex unit is a split system. Installing them requires certain knowledge and skills. It consists of two blocks: internal and external.
Composition of the outdoor unit:
- A compressor designed to maintain the flow of compressed gas - freon.
- A four-way valve is responsible for distributing freon during cooling or heating.
- Fan.
- Blowing condenser.
- Radiator. It cools and condenses freon gas
- Freon system filters, whose task is to protect the entry of foreign particles into the compressor
- The fitting connection to which they are connected copper tubes for vault with internal block
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 a drain hose.
- Control board.
- Union connection.
How to disassemble an air conditioner
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. To do this, you need to rinse the outdoor and indoor units of the split system.
In order to solve such a problem, you can use two methods: attract a specialist, but this is a very expensive method, or disassemble the internal 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 cash, and the useful experience gained will come in handy in the future.
Guide to self-disassembly of the air conditioner
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 begin disassembling the block, you should stock up on the necessary tools. To work you will need:
- “Minus” and “plus” screwdrivers of different diameters.
- Set of hexagons.
- Thin soldering iron.
- Special disinfectant for air conditioning systems.
- Brush with elongated bristles
You need to know that in order to disassemble and clean the unit, you do not need to dismantle the unit from the wall, drain the freon and open the copper route.
First you need to disconnect the device from the power supply. After this, the protective filtration located in the block is removed. You can read how to remove it correctly in the instruction manual that came with the air conditioner. The whole process is described there in very detail and clearly.
After which, the outer panel is removed from the block. And then two bolts are unscrewed, which are closed with fuses, and the frame pulls in its direction. It is secured on the top side with two latches.
The entire panel that was on the top side will be covered in mold and dirt. It needs to be sent to the wash immediately.
Using a little force, a blade is pulled out of the grooves, which is responsible for the direction air masses.
Then the lower area of the indoor unit of the unit is removed from the valve mounts, where the drainage hose and the wire supplying the air conditioner are disconnected.
If there are basic knowledge in electronics and radio engineering, then you don’t have to write it down, but when reassembling it, refer to the connection drawn on the back side of the block.
Next, the fastening 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 blade part, be covered with mold, which causes the spread of such a nasty aroma.
After that, you should unscrew the supporting bolts of the electronic motor 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 the radiator accidentally falling, it can be placed back.
Then it is necessary to remove the thermal lock located on the mounting 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 yourself. In order to avoid accidental combustion of the rubber part that transmits energy, it is necessary to very carefully heat the bolt head using a thin soldering iron, and during the soldering process you need to try to unscrew it. After successfully separating 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.
When starting cleansing, you first need to shake the can. The product is sprayed over the entire surface that requires cleaning. Wait twenty minutes. Then use a long-haired brush to scrub through the contaminated areas. 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 for complete filtration greatly depends on the cleanliness of the room. If the room environment is polluted, then the air conditioner will require frequent cleaning. In order to understand whether the air conditioner needs cleaning work, you can carry out an experiment. To do this, you should disassemble the device; if the filter is already completely clogged, then next time you need to do this a little earlier, and if the filter is still clean, then the procedure can be postponed until later. Also on some modern models, you can determine the level of filter contamination using an indicator that provides information about the current level of contamination.
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 maintenance of the device will ensure 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 have to have a little patience free time and let nothing distract you.
Disassembling on your own will help in preserving family budget and will give you new experience that will be very useful in the future. Air conditioners need to be cleaned periodically and calling a technician every time is not only expensive, but also not always convenient. As a rule, you have to wait for specialists and adjust to their arrival time.
And the ability to tinker and understand technology also brings moral satisfaction.

Service maintenance of the indoor unit of the air conditioner...
Hi all! At the request of my friends and accomplices in general, I want to write a post about the service of air conditioners, because this is already relevant in at the moment(I hope the moderators will be understanding)! The fact is that consumers are often misled by offering them service for their air conditioner ANNUALLY!!! There is no need to do this, because everything depends on the degree of pollution of the room 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 can perform this operation yourself:
So we have a regular internal block:
Below, so as not to stain 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 let's remove it completely top part housing, together with the lid...
We unfasten the bathtub (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 DISASSEMBLYING THE AIR CONDITIONER, you can see the degree of contamination and draw your own conclusion... is it necessary to clean it?
Please note... The fan impeller we need to clean!!!
We remove the impeller (if possible), wash it with a stream of water and a brush, and clean the radiator using a steam generator... VOILA:
Then we proceed to assembling the indoor unit, in reverse order! But those same mesh filters...
Fasten the lid, put the meshes...
Close the lid of the indoor unit...
We turn on the remote control to 22-25 degrees (don’t turn it on minimum... never in the heat, not a single air conditioner will give you 16-17 degrees!!! You’ll stupidly ruin it!) and enjoy the coolness!
...I'll tell you about the outdoor unit later! I would like to inform you that I have been involved in air conditioning and ventilation since 2000 and am ready to help with advice and business in this area!!! So ask away! I’ll answer later, in the evening I’ll answer everyone, because there’s a lot of work right now... I’m running away) Have a good day everyone!

If you notice that the cold air coming out of the split system has an unpleasant sweetish smell of rot, this means that the unit urgently needs preventive cleaning
In addition to the unpleasant odor, clogging of the internal components of the air conditioner leads to faster wear of the power system of the device, increased energy consumption and, most unpleasantly, can cause a number of allergic respiratory diseases.
In fact, today there are quite a lot of companies producing split systems, but they all assume a more or less unified system for constructing indoor units. Therefore, even if you encounter some design differences, the basic disassembly technique will remain the same.
The first step is to prepare a set of screwdrivers of various sizes and work area configurations. Also, do not forget to put the 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.
- Turn off the power to the air conditioner
- Remove the top cover of the unit
- Remove the air filters . Remove 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
- Disconnect terminal blocks electrical wiring, remove the electronic control unit and transformer

Of course, you can have a service technician perform this procedure, especially if the air conditioner is still running. warranty service. But if you have been using a split system for a long time and do not intend to pay a lot of money for something that you can easily handle on your own, then you should know the procedure for disassembling the air conditioner for its preventive cleaning.
In fact, today there are quite a lot of companies producing split systems, but they all assume a more or less unified system for constructing indoor units. So even if you encounter some design differences, the basic disassembly technique will remain the same.
How to disassemble the indoor unit of a split system for maintenance
The first thing you should do is prepare a set of screwdrivers various sizes and workspace configurations. Also, do not forget to put the 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.
- 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 using the remote control button, but simply remove the plug from the socket.
- Remove the top cover of the unit . Unscrew several bolts (two or three) covered with decorative plugs and remove the top cover of the indoor unit of the air conditioner. The lid, which is coated on the inside with a layer of dirt and mold, should be washed in the bathroom using a brush and detergent.
- Remove the air filters . Remove plastic filters rough cleaning air. 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, remove the special blinds from the grooves that direct the flow of cold air into the room. They, too, most likely need intensive washing.
- Disconnect the bottom cover of the indoor unit, drain pipe and power cord of the split system . Carefully press out the three latches, and then disconnect the drain pan along with the outlet hose from the internal block of the split system.
- Disconnect the wiring terminal blocks, remove the electronic control unit and transformer . To remove the control unit from the split system, carefully press out the side fasteners and then pull the device towards you. Don't 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 motor together with the rotary fan.
- Separate the motor from the fan . First, you will have to carefully heat the head of the bolt with a soldering iron to unlock the thermal lock on the engine pulley. Once the fan blades are removed from the pulley, they can be thoroughly washed in the bathtub.
Assembling the indoor unit of the split system should be done in the reverse order.
How to disassemble the air conditioner yourself to eliminate the unpleasant odor from the split system? To disassemble a wall-mounted air conditioner with your own hands, you must first become familiar with some of the features of household air conditioners.
How to disassemble an air conditioner
One day, any user of a wall-mounted, household air conditioner is faced with the following unpleasant problem: when the split system is turned on, a stream of cool air bursts out of its blowout hole, filled with a slightly sweetish smell of already stagnant mold. This means it's time for you to maintenance your air conditioner, that is, wash it thoroughly, and inside the system. There are two ways to solve this problem: the first is to call the wizard (however this method expensive), the second is independent disassembly of the split system and its subsequent cleaning on your own.
We suggest that you do everything yourself, because this way you will be able to save a certain amount of money, and besides, this skill may come in handy in the future. We present to you detailed guide on disassembling the indoor air conditioner unit, which will help you solve the problem of unpleasant odor from the split system. The considered algorithm for disassembling an air conditioner is typical, so it is suitable for many brands of modern air conditioning devices. So, to disassemble the air conditioner yourself, you will need several negative and positive screwdrivers various diameters, as well as a set of hexagonal sprockets (not for all models of split systems). If you already have such a simple arsenal, then you can start disassembling the indoor unit. Please note that when cleaning the air conditioner, you do not have to remove the device from the wall, disconnect the copper line and drain the freon.
First of all, turn off the power to the air conditioner, and then remove the protective filters from the internal unit of the device. This process is described in detail in the standard maintenance manual for your split system. Next, remove its front panel from the block; to do this, unscrew the two bolts that are covered with protective plugs, then pull the frame towards you (it is held on top by two latches). The inside of the lid will be covered with mold and dust, so immediately send it to the sink. Next, remove the blade that directs the air flow; to do this, apply a little physical strength and pull it out of the grooves. Then remove the lower part of the indoor air conditioner unit from the latches, and then disconnect the split system drain hose and its power cable.
Next you need to disconnect all the electrical wiring, and it is better to write down how the wires are located. If you are too lazy to write down, and besides, you can boast of your tremendous knowledge in radio engineering, then when you put the air conditioner back together, you can use its electrical circuit, which is located on the inside of the front cover of the indoor unit.
Next, press out the fastening brackets, and then remove the electronic unit housing and the transformer. Then you need to press back the three support latches and carefully remove the drain and outlet hose. The hole for blowing air from the indoor unit, as well as the blades of the built-in fan, will be covered with a strong coating, which emits an unpleasant odor. After this, unscrew the support bolts of the air conditioner motor, carefully lift the radiator, and remove the motor support. Next, remove the blades, as well as the engine from the cell, and you can carefully put the radiator back so that it does not suddenly fall.
Next, remove the thermal lock, which is located on the electric motor pulley mounting bolt. Please note that this is not easy to do.
