This household system is dismantled for subsequent repairs or when moving; many users solve the problem simply - call the specialists from service center. A thrifty owner who has the skills and desire can save money and do everything himself, and we will tell you how to remove the air conditioner correctly, while avoiding mistakes and negative nuances.

Any modern split system, which includes a household air conditioner, consists of blocks for indoor and outdoor locations. They are connected by two lines through which the refrigerant moves. Circulates through a tube of smaller diameter freon in liquid state from the indoor unit to the outdoor unit, the same thing runs through a thicker copper tube in the opposite direction, but in a gaseous state.

This is where problems lie that can ruin everything you do when trying to remove the air conditioner yourself.

1. As a result of improper shutdown of main pipelines, partial or complete loss of freon.
2. Air containing moisture can get into the tubes and heat exchanger, which can cause damage when the air conditioner operates in a new place - incompressible moisture enters the compressor and disables it.
3. Hitting copper tubes small particles when pulled through the wall or during improper transportation leads to rapid breakdown of the system.
4. Particular attention should be paid to the threaded bends soldered to the tubes; if they are damaged, very expensive repairs will be required.
5. Incorrectly disconnected wires. If you do not put special marks on the terminals, it may lead to incorrect connection at the new location.
6. Cutting it too short drainage tube, which discharges condensate outside the outdoor unit, you doom yourself to its premature complete replacement.
7. When transporting a product to a new location, there is a risk of losing small fasteners and parts if they are not securely fastened after disassembly.

All of the above cases lead to very expensive repairs of the entire system, so before you start dismantling the air conditioner yourself, read the instructions.

Preparation

Before dismantling the split system with your own hands, you need to prepare a tool, not a simple one from your home arsenal, but a purely professional one, as shown in the photo:

Many users do not take advice seriously professional craftsmen, how to properly dismantle any split systems. As a result, the shutdown is carried out with numerous violations: they dismantle the product without pumping freon into the air conditioner, and it leaks, which will not be as easy to replenish as many people think.

Refilling the entire system with refrigerant will result in serious financial costs:

• first, the master will check the integrity of all pipelines - 600 rubles;
• refilling an air conditioner with a power of up to 4.5 kW - up to 3 thousand rubles;
• the same actions with equipment power up to 7 kW - up to 3.5 thousand rubles.

At the bare minimum for household air conditioners, this operation will cost you at least 4 thousand rubles, depending on the refrigerant used.

Freon release

There are three ways to dismantle the air conditioner yourself:

• disassembly with freon release;
• keep the gas inside the air conditioner approximately or “by eye”;
• completely save freon using professional equipment using a special technique.

The third option gives the best effect without any losses, but many users use all methods. Experts advise completely preserving the refrigerant so that there are no problems when installing dismantled equipment in a new location.

To properly dismantle the air conditioner, you need to know the design of the split system, which consists of a closed circuit filled with freon. The main components are a compressor, an evaporator with a condenser and a system of copper pipes that connects the entire structure and ensures the supply and removal of refrigerant.

This is what the schematic diagram of a modern air conditioner or any split system looks like:

To turn off the air conditioner yourself without losing freon, you need to pump it into the condenser; to do this, when the equipment is operating in cooling mode, you should close the valve between the product and the thin-diameter tube. When all the refrigerant is pumped into the condenser within a minute - that’s exactly how long it will take to completely pump gas into the condenser, you need to shut off thick tube valve, turning off the freon supply, and “close” it in an improvised trap.

Dismantling

Before dismantling external unit, need to be disconnected copper tubes, but in practice they are not reused, since their extension is strictly prohibited. It is necessary to cut them at a distance of about 200 mm from the fitting and caulk the sections for complete sealing.

Attention! When storing the product disassembled for a long time, the tubes are filled with nitrogen and ensure tightness to prevent oxidation of the inner surface.

Outdoor unit

The instructions say: after working with copper tubes, you must remove thermal insulation As a rule, all masters work together, one indoors and the other outside. Thus, dismantling is carried out faster: the partner has turned off the power and now you can disconnect the wires at the place of their connection, first marking the terminals.

The tubes are straightened manually so that they pass through the holes in the wall without interference, and the end of the cable is screwed to them to remove it into the room.

After this, unscrew the nuts that hold outdoor unit on special brackets, together with an assistant, carefully remove the block and move it inside the apartment. IN last resort brackets are removed from the wall of the building.

Important! During transportation and storage, the dismantled outdoor unit is positioned only vertically to prevent mechanical damage from shaking - it is inserted into a box with foam plastic underneath.

Compressor

Sometimes only the outdoor unit is dismantled, for example, if only the compressor needs to be repaired, and the indoor unit of the air conditioner remains in place. During similar operations, the internal block of the split system is also not touched.

The main condition is to properly dismantle the compressor:

• remove the cover from the outdoor unit;
• then disconnect suction and discharge tubes;
• all electrical wiring is turned off;
• the fasteners of the condenser and fan are unscrewed;
• remove the capacitor from the block housing;
• access to the compressor is open - remove the fastenings and dismantle it.

With such actions, the risk of causing damage to pipelines is eliminated and real opportunity repair other elements located in the casing of the outdoor unit, if necessary.

Indoor unit

Dismantling indoor unit an air conditioner has its own very specific nuances, without knowledge of which all your efforts will be useless, and in some cases careless actions can lead to breakage of rather delicate fasteners, for example, evaporator latches or clamps holding the unit on the guides.

To understand how to remove an air conditioner from a wall, you need to study the instruction manual, which contains the section you are interested in. Many users will not be able to do this operation and will have to turn to professionals.

Remove the indoor unit the air conditioning system will only work after removing the front panel, then you also need to disconnect all the electrical wiring, freon inlet and outlet pipes. You need to disassemble the tangle of wires carefully and without fuss. But this is not all the testing - manufacturers have reliably blocked access to evaporator latches ensure that dismantling is carried out only by specially trained people.

Access is closed by a lid, the latches of which are pressed quite tightly to the wall - you can get to them using two screwdrivers with a very thin tip. Your partner must hold the entire block during this labor-intensive process.

After removing the evaporator, you can unscrew mounting plate , which blocks access to the electrical wires and freon pipes supplying the product, hidden in a special gutter inside the wall. Last to unscrew decorative box, which runs along the outer wall all the way to the outer unit.

The disconnected wires are carefully twisted and placed in a separate box for transportation. To help home craftsmen, there is a video on how to dismantle an air conditioner on your own, without turning to specialists:

Dismantling in winter

Many users are interested in the question: how to remove a split system in winter period when due to low temperature it is impossible to pump refrigerant into the condenser. The oil in the compressor will thicken, and all attempts to turn it on can end very badly.

If you have a special model equipped with a kit where there is heating of the compressor crankcase and the entire line drainage system, as well as a block that slows down the rotation of the fan, then your intentions will be crowned with success. If it is not available, you can use a special refrigerant collection station, which is connected in the same way as a pressure manifold.

A few more practical tips: you can start dismantling yourself only when you are completely confident in own capabilities, and have a qualified partner. Also, having a special tool makes the job much easier.

For dismantling the most popular type of air conditioners - split systems - specialists charge a fee of 1 rub. for every kilowatt of power. Many owners of cooling devices who have to move, in order to save their money, undertake to dismantle the air conditioner themselves. A number of useful recommendations will help you get the job done cleanly and avoid fatal mistakes.

Possible problems with self-removal

The story about how to dismantle an air conditioner with your own hands should begin with a warning about the pitfalls that await an untrained technician. Here's what can happen:

1. Refrigerant leak: freon escaping into the atmosphere will not cause an environmental disaster, there is no need to be afraid of it. But such an event will not be in vain: when installing an air conditioner in a new place, you will have to pay for its refilling. Therefore, it is highly advisable to dismantle the device so that all the existing refrigerant remains inside it.
2. Getting into inner circuit water or dust: such an “additive” to the refrigerant quickly renders the compressor unusable. Perhaps, at first glance, water may seem like a completely harmless substance, but you need to take into account that in the evaporator it will freeze, turning into ice. And these are solid particles, the presence of which is “incompatible with the life” of the compressor. To minimize the risk of moisture entering the internal circuit, you should avoid dismantling the air conditioner during rain or snowfall.
3. Falling of the outdoor unit: even if the outdoor unit hangs next to a balcony or window, it is extremely inconvenient to work with it. Moreover, this unit is quite heavy, so that without calculating your strength, it can easily be dropped. Professionals are insured against such accidents, since when working above the first floor they use an aerial platform or equipment for industrial mountaineering. To be on the safe side, the average person should invite an assistant.
4. Damage to device elements: the most noticeable damage is damage that causes depressurization of the circuit. The crack may be completely invisible, but it is quite sufficient for freon to leak or dirt and water to get inside. To avoid such troubles, first of all you should be careful.

When performing such a complex operation with your own hands as disconnecting the evaporator of the indoor unit, it is highly advisable to use not improvised tools - a screwdriver and pliers, but professional ones designed specifically for it.

Kit necessary tools and materials for dismantling

Users at this stage often use whatever they have to, resulting in damage to the evaporator tubes located close to the fastenings. The problem is that a professional tool is quite expensive and even renting it can cost an amount quite commensurate with the cost of the services of a qualified craftsman.

Preparing the air conditioner: “packing” freon

So, first of all, it is necessary to ensure the safety of the refrigerant. To understand how this is done, you need to remember the design of the split system. It is a closed circuit filled with freon, which consists of a compressor, two relatively speaking chambers (evaporator and condenser) and freon pipes connecting these elements (copper tubes).

Split system design diagram

The refrigerant flows from the condenser to the evaporator in liquid form, so the tube through which it flows has a smaller diameter.

Along the second freon line - from the evaporator to the compressor - freon flows in a gaseous state, so the diameter of this branch is increased.

To carry out dismantling without loss of gas, it is necessary to collect it in a condenser:

• while the air conditioner is operating, the valve between the condenser and the thin tube is closed for cooling;
• when all the refrigerant, thanks to the operation of the compressor, “moves” into the condenser, you will also need to close the valve between the thick tube and the compressor.

Shut off the refrigerant

Important point: After what time should the second valve be closed? It is best to monitor gas pressure using a vacuum pressure gauge. But for this you will have to borrow a special tool from the masters - a pressure gauge manifold.

Those who do not have this option simply wait about a minute: as experience shows, during this time a household air conditioner usually manages to pump almost all the freon into the condenser.

Pressure gauges for monitoring pressure when pumping freon

Let's move from theory to practice:

1. If you managed to get a manifold, attach it to the nipple (schredder valve) on the fitting to which the “gas” freon line is connected. If such a tool is not available, we simply skip this point.
2. We turn on the air conditioner and enter the settings from the remote control: cooling operation, turbo mode, temperature as low as possible (the permissible minimum must be specified in the passport). So the device should work for 10 minutes.
3. On the external unit, find the valve to the fitting of which the liquid freon line is connected (remember that it is thin). Under the protective cap, which must be removed, you will find hexagon slots. After inserting the key, the valve must be closed.
4. Now you should watch the pressure gauge or, if there is none, the clock. In the first case, we wait until the device shows the presence of vacuum; in the second, we time it for 1 minute.
5. Next, you need to remove the protective cap from the second valve on the outdoor unit, to which the thick “gas” line is connected, and also close it using a hexagon. After this, turn off the air conditioner immediately. We return the protective caps to their places.

That's it, now the freon is trapped and the system can be safely disassembled and dismantled.

Instructions for dismantling the air conditioner yourself

Let's proceed directly to uninstallation.

Outdoor unit

Disconnect the freon lines. This can be done by unscrewing the nuts with which the lines are screwed to the fittings of the outdoor unit. This method is used if the length of the tubes allows them to be used in a new location. Open fittings must be securely sealed with electrical tape or tape - this will prevent them from clogging.

Dismantling the outdoor unit

But in most cases, freon pipes are not reused, especially since their extension is not allowed. Then the tubes are simply cut with a pipe cutter at a distance of 150–200 mm from the fittings, immediately caulking their ends with a bench vice.

Caulked highways

Advice. If it is known that the air conditioner will be stored unassembled for a long time, the tubes can be filled with nitrogen and sealed tightly. Unlike air, or more precisely, the oxygen contained in it, nitrogen does not lead to oxidation of the material.

After all manipulations, it is necessary to remove the thermal insulation from the outer part of the freon pipes.

After making sure that the device is disconnected from the network, remove the protective cover over the electrical cable connection point. Its terminals must be marked in some way to avoid confusion when connecting in a new location. After this, you need to unscrew the clamps with which the cores are screwed to the contacts of the outdoor unit. The freed end of the cable is screwed to the freon pipes, which are then manually straightened in order to be able to pull them out through the hole in the wall.

Now we unscrew the nuts holding the outdoor unit to the brackets, and together with an assistant, remove it, and then the brackets themselves.

Note! The outdoor unit must be in an upright position during storage and transportation. When transporting, it is very important to avoid shaking and shock - for this it is better to place the unit in a box with foam plastic pre-laid in it.

Disconnecting the compressor

If the air conditioner is dismantled to repair the compressor, the latter must be properly disconnected. This is done like this:

1. The covers are removed from the outdoor unit.
2. After this, you can disconnect the suction and discharge pipes from the compressor.
3. Disconnect the wires supplying the compressor and fan.
4. We unscrew the fastenings holding the valves and the capacitor.
5. We remove the condenser, gaining access to the compressor mounts.
6. We remove the compressor.

By doing this, you will eliminate the risk of damage to the piping pipelines. Another plus: it becomes possible to repair several elements of the outdoor unit at the same time, which will allow you to cope with the task faster.

In order to be able to operate the compressor, you need to pour out the oil in it.

In case of piston model it drains through the suction pipe without any problems. For spiral and rotary models, you have to drill the bottom (hole diameter is 5–6 mm). You cannot drill through, otherwise chips will get inside. A thin septum is left, which is then pierced with a punch.

How to remove the indoor unit

To gain access to the latches of the indoor unit, you need to remove the front panel from it. Then disconnect the freon lines and electrical wires, snap off the latches and remove the block from the guides.

Dismantling the indoor unit

Note! At this stage, the average person faces some difficulties: careless actions can easily damage the evaporator latches.

The manufacturer usually closes this element with a lid, the latches of which are pressed against the wall. They were made difficult to access on purpose: this precaution, according to the developers, is a guarantee that only specialists will dismantle the device. To get to the fasteners, use two thin screwdrivers. In this case, it is necessary for someone to hold the block.

You should also be careful when unlatching the latches that hold the block on the guides. If they are damaged, the device cannot be firmly fixed in a new place and it will quickly fail due to vibrations.

Be careful with latches!

Having removed the internal unit, unscrew the mounting plate, remove the freon pipes with the power cable from the wall and unscrew the decorative box laid along the outer wall.

Features of work in winter

At low temperatures there is no way to pump freon into the condenser: the oil in the compressor becomes thick and an attempt to turn on the air conditioner in such conditions will lead to damage to the supercharger. This danger does not occur only in models equipped with a so-called winter kit, which includes heating of the compressor crankcase and drainage, as well as a fan speed retarder.

Pressure gauge station for refrigerant collection

Those who have similar system no, they can remove the refrigerant using a pressure gauge station to collect freon. It is connected, like the pressure manifold, to the shredder valve.

Video: dismantling the air conditioner and then installing it in a new location

The procedure for dismantling the air conditioner is technically quite simple. The difficulty, from the point of view of the average user, is that some operations are difficult to perform without professional tool. If you still firmly decide not to turn to specialists, we recommend inviting another person to help - then even without special tools the task will be quite feasible.

The air system has a distributed circuit for transporting refrigerant between the outdoor and indoor units. Such a device has many advantages, except for one thing - dismantling the system is much more difficult than dismantling a monoblock. And often ignorance of how to remove the air conditioner leads to its failure.

How to properly remove an air conditioner

There are three mandatory conditions to remove the air conditioner yourself:

• The outdoor unit must be within reach. If he stands on the facade apartment building above the level of the second floor, then it can only be dismantled from a window or from a balcony. Otherwise, you need to involve industrial mountaineering specialists.
• To remove heavy blocks from the wall and properly turn off the compressor, you need at least one assistant.
• It is necessary to rent a pressure gauge station specifically for the type of freon that is pumped into this air conditioner model.

Note. The last point concerns stations with conventional (arrow) pressure gauges. Digital manifolds are customized to the refrigerant brand.

Precautions

If the air conditioner is out of order and cannot be repaired, then it is easy to remove it - there is no need to save freon, the tightness of the compressor, condenser and evaporator is not important.

You cannot do this with a working air conditioner. And in this case, the main thing is that dust and even air do not get inside the system. Otherwise, we can talk about guaranteed compressor output after installation and start-up of the air conditioner in a new location. Reason - device feature vacuum pump.

Freon is extremely fluid, and the temperature difference at the inlet and outlet reaches several tens of degrees. None of the seals and rings used in conventional pumps and compressors will withstand such operating conditions. The required tightness is achieved through extremely precise adjustment of the surface of the moving elements of the pump to the internal geometry of the chambers. The slightest scratch from a solid particle leads to compressor failure. And such a particle could be a grain of ice formed when moisture in the air trapped inside freezes.

This is why new air conditioners are sold full inert gas, which is pumped out with a vacuum pump before pumping in freon.

When removing the air conditioner yourself, the freon must be pumped out and the units disconnected. This must be done so that dust and air do not get inside the system. That is, create a vacuum there. And it is advisable to save all the freon (or most of it) so that it would be easier to get the system into working condition in a new place.

Preparation

To properly remove the air conditioner, the only professional equipment you need is a pressure gauge station, which can be rented.

Every home craftsman has the remaining tools:

• a set of wrenches and hex keys;
• screwdrivers;
• pipe cutter or side cutters;
• hand bench vice;
• pliers.

Freon release

There are two ways to dismantle a working air conditioner:

1. Using a pressure gauge station to collect freon in an external unit.
2. Using a freon pumping and collection station connected to a special two-valve cylinder. The station has its own pressure gauge manifold and a compressor for pumping out refrigerant in liquid or gaseous state.

The first method is more “affordable”, but it can only be used when starting the air conditioner - freon is transported using a standard compressor.

The second method is universal. It can be used even in winter, when the air conditioner cannot be turned on due to low outside temperatures. The advantage of this method is that the external unit will be evacuated - without freon in the condenser. Which is much safer when transporting to a new place. But renting such a station and a cylinder will cost more than a regular pressure gauge manifold.

Freon collection in the external unit

On the side of the outdoor unit body there are two fittings from which tubes extend:

• thin - for transporting liquid freon from the condenser to the evaporator;
• thick - for pumping freon gas into the condenser.

Both fittings have shut-off valve heads under the caps. An outlet with a nipple extends from the gas head.

Freon is collected in the condenser in the following order:

1. Remove the protective covers from the fittings and nipples.
2. The manifold is connected to the nipple.
3. Turn on the air conditioner to maximum cold.
4. After a few minutes, close the valve of the liquid fitting, stopping the supply of freon to the evaporator.
5. The pressure is monitored using a pressure gauge.
6. When the arrow shows “-1 MPa”, tighten the gas fitting valve with a hexagon and immediately turn off the air conditioner (for which an assistant is needed) - during prolonged idle mode, the compressor pump may fail.

The pressure gauge reading “-1 MPa” means that all the freon is in the condenser, and there is a technical vacuum inside the evaporator, in the tubes and in the compressor.

After this, you can separate the blocks.

Dismantling the air conditioner step by step

Disassembly while maintaining the functionality of the dismantled air conditioner is as follows:

• sealing of pipeline fittings;
• disconnecting and dismantling the external unit from the facade;
• dismantling the indoor unit in the apartment.

Below are instructions for dismantling a wall-mounted air conditioner.

Outdoor unit

To remove the outdoor unit of the air conditioner, first disconnect the tubes.

There are two ways:

• Unscrew union nuts, which press the flared edges of the tubes to the flanges of the fittings of the outdoor unit. And in place of the nuts, pre-prepared caps are screwed on. The advantage is that the tubes remain intact. The disadvantage is that there is a high risk of air getting into the compressor.
• Side cutters are used to cut copper tubes (about 15 cm from the fitting). The edges are folded and clamped (caulked) using a vice. The disadvantage is that new tubes must be installed in a new place. The advantage is that the operation is quick and the likelihood of dust getting inside with air is much lower.

Note. The other cut edge of the tube must also be caulked to protect the evaporator of the indoor unit.

The next step is to disconnect the cables (signal and power), remove the fastenings of the unit to the frame on external wall and lift him into the room.

Compressor

One of the situations when it is necessary to remove the outdoor unit may be to replace the air conditioning compressor. And in this case, the dismantling algorithm is slightly different. The differences are as follows:

• Freon must be completely removed from the system. The right way- collect it in a cylinder using a freon pumping station. Incorrect, but simple - release it into the atmosphere (if the compressor is replaced in the warm season and the air temperature is higher than the boiling point of freon at normal pressure).
• There is no need to caulk the tubes - after installing a new compressor, the system is “pumped out” with an external vacuum pump.

It is impossible for a non-specialist to replace the air conditioning compressor on his own. In addition to the vacuum pump and pressure gauge station, it is necessary to have gas burner to disconnect the suction and exhaust pipes of the old compressor from the system, and then solder the new unit to the system. And even if you rent equipment, you need to have the skills to handle it.

You can remove the unit yourself, but it is better to invite a professional to replace the compressor.

Indoor unit

Most household split systems have a wall-mounted indoor unit (although there are other placement options). But with the exception of a ducted air conditioner, the remaining types are dismantled according to the general principle.

To remove the internal wall unit, proceed as follows:

• remove the housing cover;
• disconnect cables and wires;
• cut and caulk the copper tubes that go to the evaporator of the indoor unit;
• trimmed drainage pipe, drain the condensate;
• “snap off” the latches securing the housing to the mounting plate;
• remove the block and unscrew the plate from the wall.

Dismantling in winter

The air conditioner can also operate in winter time. And not only as a heater, but also in cooling mode (for example, in rooms where servers are located).

Note. It is possible to collect freon in the condenser of the outdoor unit only when operating in cooling mode - in heating mode it already works as an evaporator.

The peculiarity of working in winter in this mode is that there is a lower temperature limit, which is affected by the type of refrigerant, type of air conditioner and additional equipment. This dependence is also related to the design features of the compressor - it is oil-based, and oil thickens at low temperatures. For conventional air conditioners, the lower working temperature lies in the range from +5°C to -5°C, for inverter ones - up to minus 15-25°C.

Before dismantling the split system, these nuances must be taken into account. And if the temperature is below the specified limit, and the air conditioner is not equipped with a “winter kit” with heated compressor crankcase, then to remove the outdoor unit you must use a freon pumping and collection station (it has an oil-free compressor).

Regular maintenance of the air conditioner requires disassembling its internal and external units. This is necessary when replacing parts of the split system and completely cleaning it. It is worth understanding the features of the process and the consequences of incorrect disassembly.

How to remove the indoor unit

To remove the indoor unit of any type of air conditioner, you need to unclip the lower clips. For most devices, they are located at the bottom and are indicated by arrows or serifs. Types of clips:

• The hook to the wall plate is made from above. In these cases, the clips are pressed upward.
• Bottom hook on the plate. In such devices there are additional holes at the bottom. The fasteners are pulled down from the block.
• Clips located under the decorative cover. First remove the cover and then press out the fasteners.

The removed internal air conditioner module is easier to disassemble.

Disassembling the indoor unit of the air conditioner

You can disassemble the internal unit of the split system after disconnecting the device from the network. Then open the housing cover and take out the filters. The next step is to remove the housing:

• Any air conditioner has screws on the bottom that are easy to find under the plugs. They need to be unscrewed.
• There may also be screws or latches under the cover behind which the filters are located. After unscrewing them, you can slightly open the lower element of the housing.
• The next task is to release the latches located on the top of the case. They are quite rigid; to disconnect them you need to know the fastening features. Most often, they can be unlocked by pulling the bottom of the case toward you and up.
• All that remains is to disconnect all the wires, if any.

Having opened the blinds slightly, it is easy to remove the body by pulling it towards you.

The next step is withdrawal drainage tank. Some models are made monolithic, so it is impossible to separate the tray from the body. It is important to understand the features of its installation in order to install it correctly during assembly.

It is recommended to prepare a container for condensation from the tray. To disassemble the container, simply unscrew one screw and then disconnect the clips at the bottom. The blind motor must be disconnected from the tray. After removing the container, separate the “tail” of the drainage hose.



Air conditioner indoor unit fan (impeller)

The next task is to remove the fan (shaft). This procedure is the most responsible and complex. A simple option for removing the shaft is applicable when it is removed to the left without affecting the control unit and engine:

• Unscrew and release the left side of the radiator from the device body.
• Unscrew the fastening on the right in the shaft itself a few turns. This screw is often over-tightened, so it is important to be careful not to damage the head of the fastener or break the blades.
• Remove the shaft from the bottom of the housing, ensuring the safety of the parts. Since the fan is often installed quite tightly, removing it requires a lot of experience. The screw can be held with a screwdriver while pushing the shaft.

When installing the shaft into the device body, the screw must be exactly in its original position. Otherwise the fan will touch the walls.

There are more difficult option removing the fan. If the shaft is pulled out from right side, you will have to remove the electric motor and control unit.

Sequencing:

• Remove the control unit from the housing. This will require disconnecting all wires and sensors. Then disconnect the latches and unscrew the screws securing the control unit.
• Unscrew all motor mounts. Disconnect the casing with the shaft.
• Carefully study how the shaft is disconnected from the motor. Carefully bend the copper tubes leading to the radiator.

Disassembling the external module

Dismantling a mobile or window air conditioner does not take much time - just remove the device from the window or remove the air duct. When disassembling a full-fledged split system, it is necessary to preserve all the refrigerant.

The connecting tubes through which freon is transported have different diameters. A thin channel serves to transport liquid refrigerant. The large tube is designed to pump freon gas. When disassembling the air conditioner, it is necessary to “drive” the refrigerant into the outdoor module. Then you can turn off the main channels. To pump the refrigerant, while the device is running, it is necessary to screw in the pipe with liquid freon, which flows from the outdoor unit into the room. The device will pump the gaseous substance into the outdoor unit in 1 minute. After this, you should immediately turn off the device.

It takes two people to disassemble the outdoor unit of the air conditioner. This way you can eliminate unnecessary risk and reduce work time.

After disconnecting the device from the power supply, disconnect the cables by marking the terminals.

The copper ducts that carry the refrigerant can be straightened yourself with care. He goes into the room with them electrical cable. It is screwed to the end of the tube. Then you need to unscrew the nuts that hold the outdoor module. It takes two people to remove the block. Lastly, the brackets are removed from the wall.

The removed outdoor unit requires vertical storage and transportation. To exclude possible damage it is placed in a box with foam.

Removing the compressor

In some cases, only dismantling the outdoor unit is required, for example, when it is necessary to adjust the operation of the compressor. In this case, the indoor unit remains in place. The main task is to remove the compressor correctly:

1. remove the cover of the outdoor unit;
2. disconnect the discharge and suction pipes;
3. disconnect the electrical wires;
4. unscrew the fastening elements of the fan and condenser;
5. remove the capacitor from the housing;
6. dismantle the compressor mounts and the part itself.

By performing this sequence of actions, you can reduce the risk of damage to pipelines and gain access to other elements located in the housing.

Consequences of improper dismantling

If dismantled incorrectly, it is easy to damage the air conditioner. Possible unpleasant consequences.

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

Once any user of the wall, household air conditioner faces the following unpleasant problem: when you turn on the split system, 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 unpleasant odor from a 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 it electrical diagram, which is located on inside front cover of the indoor unit.

Next, press out the mounting brackets, and then remove the housing electronic unit and a 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 spend extra money, you can clean the device yourself, and besides, you now know how to disassemble the air conditioner yourself.
