A few rules on how to dismantle a household air conditioner. How to remove the split system yourself Transfer the split system with your own hands

Installation and dismantling of LG, Panasonic or other brand air conditioners are not easy tasks that require special skills and abilities. It is no coincidence that this procedure is performed by professionals, and its cost is quite high. However, in case of emergency, you can remove the air conditioner yourself with your own hands, if you know and follow the correct procedure, as well as have the necessary tools. About all stages of the process step by step, as well as about the features of winter dismantling and the nuances for split systems of different brands - in the material below.

When to remove the split system is not necessary

In some cases, it is not necessary to dismantle the split system, for example, when carrying out cosmetic repairs. For wallpapering, there is no need to completely remove the air conditioner - just unfasten the latches, remove the indoor unit from the mounting plate, unscrew it, paste the wallpaper, and then return the equipment to its place.

On a note! If the house is undergoing repairs, and plastering, leveling, cladding or other actions with the walls will be performed, it is not necessary to dismantle both blocks - it is enough to disconnect only the inner one. The length of the route should be sufficient for the subsequent installation of the node.

Precautionary measures

If the air conditioner is broken and cannot be repaired, it is very easy to dismantle it, since there is no need to take precautions and preserve freon, as well as the integrity of vital components. With working equipment, you need to act differently. Not only dust, but also air must not be allowed to enter the system, otherwise, after installation and subsequent launch of the device in a new place, it is almost guaranteed to be damaged. Also, when dismantling a split system, it is important save freon so that you do not need to download it again, since this service will cost a lot.

Advice! During dismantling, you need to carefully work with the wires. When they are turned off, it is recommended to take a picture of the connections or make notes. Incorrect connection can lead to equipment failure.

Only if the owner of the climate equipment is sure that he will be able to correctly fulfill the above conditions, you can proceed to dismantle the air conditioner on your own.

Dismantling step by step

The need to remove the air conditioner may arise for several reasons: when moving to another home, during repairs in the apartment, to fix a breakdown in the equipment itself, etc. Depending on the situation, it may be necessary to completely or partially dismantle the split system. How to remove only the indoor unit from the wall was discussed above, and to completely dismantle the equipment, you must adhere to the following algorithm:

carry out preparatory work;
lower freon;
turn off and dismantle the outdoor unit;
disconnect the compressor (if necessary);
remove the indoor unit.

All actions must be performed with caution and according to the instructions so as not to damage the air conditioner.

Preparatory work

Preparatory work includes the collection of the necessary tools, among which you will need professional ones. So, the master should have:

a set of slotted and wrench screwdrivers;
a set of socket wrenches;
pliers;
manometric station;
pipe cutter and side cutter;
knife for construction work;
a set of open-end and adjustable wrenches;
screwdriver;
drill.

Important! If the outdoor unit is removed at a considerable height, safety equipment will be required.

Freon descent

Before carrying out work on the dismantling of the air conditioner, you will need to lower the freon. If you plan to reinstall the instrument in a different location, this procedure must be followed so that collect the refrigerant in the outdoor unit. There are two ways to solve this problem: the first one is with the help of a manometer, the second one is by means of a refrigerant recovery and recovery station, which is connected to a cylinder with two valves. The device used in the latter case is equipped with its own pressure gauge and a compressor that allows you to pump out freon in liquid or gaseous form.

First way is simpler, but it is only used if it is possible to start the device. Then the movement of freon to the outdoor unit is performed using its own compressor.

Second method more difficult, requires skills, and renting such a station is very expensive. Its advantage is that it is possible to pump out freon even in winter, when the launch of equipment is not allowed. In addition, the outdoor unit is evacuated and no refrigerant remains in the condenser, which is safer when transporting the unit.

To collect freon in the outdoor unit of the air conditioner with a manometer, you need to find on it two fittings with thin and thick tubes. The first is used to transfer the liquid refrigerant to the evaporator from the condenser. The second is necessary to pump freon into the condenser in gaseous form. At each of the fittings, the heads of the shut-off valves are closed with caps, while the gas valve is equipped with a branch with a nipple. Next, to collect the refrigerant in the outdoor unit, follow these steps:

remove the protective covers from the nipple and fittings;
connect the pressure gauge to the nipple;
run the split system for maximum cooling;
after a few minutes, shut off the flow of refrigerant to the evaporator;
observe the readings of the manometer.

When the value appears on the device "-1 MPa" it is necessary to close the gas fitting hexagon and immediately turn off the split system. It should not be allowed to work for a long time in idle mode, this may result in compressor failure.. That is why it is recommended to work with an assistant, and not on your own - not everyone can quickly run to the split system to turn it off.

On a note! The value "-1 MPa" indicates that the refrigerant is collected in the condenser, and a technical vacuum has formed in the remaining nodes.

Removing the outdoor unit

After the refrigerant is drained, the blocks should be dismantled. But before that, you need to disconnect the tubes, for which you can use one of two methods.

First method- unscrew the nuts with which the tubes are screwed to the fittings. Special covers are put on their place. So the tubes will remain intact, but with this procedure, the air is likely to be inside the compressor.

Second method- step back from the fittings about 15 cm of the tube and cut with side cutters. Then the edges must be bent and clamped with a vise. With this method, a replacement route will be required, but the procedure itself is quick, which means that air with dust is less likely to enter the compressor. Similarly, cut and pinch the pipe near the indoor unit to protect the evaporator.

Removing the compressor

Sometimes the outdoor unit is removed to repair the compressor. Then the dismantling actions look different - refrigerant is completely removed from the system. To do without the loss of freon, it is pumped into the cylinder using a special station, and in the summer it can be released into the atmosphere.

On a note! When dismantling the compressor, it is not necessary to clamp the tubes or close the valves with covers, because after installing a new working compressor, the outdoor unit is evacuated with a special pump.

Compressor replacement work it is recommended to entrust to specialists, since for their implementation it is necessary to have a large amount of professional equipment: a vacuum pump, a pressure gauge, a gas burner. If the user wants to perform these actions himself, you should:

remove the protective cover from the outdoor unit;
using a gas burner, disconnect the nozzles of the discharge and suction pipes;
disconnect the electrical cable;
unscrew and remove the fasteners holding the fan and condenser;
take out the capacitor;
remove the fasteners and dismantle the compressor.

Now you can remove the pulley from the compressor or do other work. Installing a new compressor performed in reverse order.

To dismantle the indoor unit, you will need:

pull out the protective plugs according to the instructions, unscrew the fasteners, remove the housing cover;
disconnect the power cable by disconnecting it from the terminals, pull it out of the air conditioner;
remove the drain tube and substitute a container to drain the remaining liquid;
cut, bend and clamp copper pipes, as on the outdoor unit;
unfasten the fasteners and remove the block from the mounting plate;
unscrew the screws that secure the plate to the wall and remove it.

Features of the process in winter

Most modern split systems work both in summer and in winter. They can be used for space heating or for cooling, for example, server rooms. You need to know that you can collect freon only by running the air conditioner in cooling mode. The difficulty of working in cold weather is that there is a lower temperature limit at which the split system is functioning properly. Such limitations are explained by the operation of the compressor on oil, which tends to change its consistency and become thick at low air temperatures.

On a note! For conventional air conditioners, the lower threshold is set in the range from +5°C to -5°C, for inverters - up to -15°C or lower (maximum value -25°C).

In this regard, when dismantling equipment, it is necessary to take into account the air temperature outside. In winter, if the “winter kit” (heating compressor crankcase) is not installed on the split system, to carry out work to preserve freon you need to use a special station, since it uses an oil-free compressor.

Process features for different types of air conditioners

The process of dismantling the air conditioner may differ depending on its type. In domestic conditions today, the most commonly used split systems consisting of an indoor and outdoor unit. The process of removing them has been presented above.

The second type of air conditioners for home use is window devices. They consist of one block, which is mounted in the window or in a special hole in the window, prepared for the technique. Dismantling in this case is very simple: it is enough to remove the device from the seat, after removing the retaining fasteners.

In addition, in everyday life are often used mobile air conditioners. These devices do not require installation, and therefore - and subsequent removal.

Other types of air conditioners ( channel, cassette, column etc.) are used for cooling retail spaces, industrial halls, etc. Only a group of professionals can handle their dismantling.

Important! Independent maintenance and dismantling of professional climatic equipment is not allowed. To carry out any work with this equipment, you should contact a specialist.

Consequences of incorrect dismantling

Improper dismantling of the air conditioner can have a number of unpleasant consequences:

the cooling circuit will lose its tightness, and / or freon will leak - fixing this problem will be very expensive;
particles of dust or water droplets can get inside the circuit, which will adversely affect the operation of the compressor - which is why it is not recommended to remove the split system during rain or snowfall;
there is a risk of the outdoor unit falling from a height, which will lead to its breakdown and subsequent replacement;
mechanical damage to one of the blocks or the route may occur, which is fraught with depressurization of the case, leakage of refrigerant and ingress of moisture and dirt.

Thus, so that freon does not leak out, liquid or dust does not penetrate into the system, and the equipment does not receive damage, it is necessary to act as carefully as possible and follow the dismantling rules.

So, despite the fact that it is recommended to entrust the dismantling of the air conditioner to professionals, if necessary, this operation can be carried out independently. To do this, you will need to assemble or rent a special tool, as well as use the instruction manual, which describes in detail all the necessary actions. During work, care must be taken so as not to damage the equipment. To help the home master on the Internet, there are many training videos dedicated to this operation, and the process itself is approximately the same for equipment from different brands.

When doing repairs or moving to a new place of residence, it is sometimes necessary to remove the air conditioner. For this, professionals are usually called, but if you wish, you can perform the procedure yourself. The process is quite complicated and requires compliance with certain rules and security measures, but with sufficient accuracy and strict adherence to the instructions, a person familiar with the technique can save a lot.

Possible problems

Untrained people often make the same mistakes when trying to dismantle the air conditioner with their own hands. Such oversights in work can lead to unpleasant consequences, among which:

In most of these cases, the problem can only be solved with the help of expensive professional repairs, and sometimes a complete replacement of the device may be necessary.

Dismantling the air conditioner How to remove the air conditioner while preserving freon

Therefore, removing the air conditioner on their own is only for those who are completely confident in their abilities, observe the utmost accuracy during the process and strictly follow all the rules.

Dismantling a split system so as not to damage anything is a rather difficult process that requires a lot of time and effort. For convenience, do-it-yourself can be divided into several stages, each of which should be considered in detail in order to take into account all the nuances.

Preparatory stage

Before you start working with the device, you should prepare a set of necessary tools. It is desirable that this be professional equipment designed to work with a specific device, but ordinary devices that are available at home for every person who at least sometimes works with household appliances will also work. To disassemble the standard model air conditioner, you need the following tools:

If part of the split system is located on the wall of a high-rise building, you need to take care of the equipment that allows you to get to it. If there is a window or balcony next to it, the structure can be tied with ropes and dragged in, otherwise it will be necessary to buy or rent special equipment.

Dismantling the air conditioner with subsequent installation in another place

Descent and collection of freon

Before removing the air conditioner from the wall, all the refrigerant must be pumped out of it. To do this, it is collected in the outdoor unit of the device. To achieve this result, you need to follow these steps:

There are two ways to understand when all the freon has collected in the evaporator. The first is to roughly calculate the time by waiting 40-50 seconds before sealing the outdoor unit. Second: determine the pressure using a manometer. The reading on it should be -1 MPa before turning off the air conditioner. This figure means that all the freon has collected in the outdoor unit, while a technical vacuum has formed in the internal one.

Do-it-yourself air conditioner dismantling

Removing the outdoor unit

After the freon is collected in the outdoor unit, it is necessary to disconnect the outdoor unit from the indoor unit. The process requires caution, a safety net from an assistant is necessary, since the work will be carried out at high altitude. Sequencing:

Masters, instead of unscrewing the nuts from the fittings, most often simply cut the copper tubes at a distance of about 15 cm from them. Then their edges are bent and clamped with a vise, securely closing the passage and minimizing the likelihood of air, dust and other foreign particles getting inside. The disadvantage of this method is that after moving the air conditioner to a new location, it is necessary to cut off the bent edges and change the tubes - their extension and reuse is prohibited.

The bracket of the outdoor module is removed last, after the freon tubes and other communications with the inside of the device are disconnected from it. It is attached to the wall with ordinary bolts, which are easy to unscrew with a wrench.

Dismantling the indoor unit of the air conditioner

Working with the indoor module

The last step is to disconnect the part of the split system that is installed indoors. At this stage, it is necessary to dismantle the air conditioner correctly. in the following order:

On this, the removal of the air conditioner can be considered complete, but do not forget about caution when transporting the split system to a new place. If during transportation one of its parts is damaged, then you can easily lose freon, and then all efforts to dismantle the device yourself will be in vain.

Transportation of the device should be carried out only in a strong cardboard box, all the walls of which are covered with foam, and then the device is wrapped in a soft bubble wrap.

Dismantling in cold weather

If the temperature drops below -5 ° C (this is the cooling limit for most “home” air conditioners, with industrial machines the figure may be different), then additional difficulties may arise with the removal of the split system. This is due to the fact that under such conditions it will not be possible to completely pump freon into the external module, part of it will have to be released into the atmosphere. In addition, at sub-zero temperatures, you cannot remove the plugs and open service ports, so the device will have to warm up. Even from frost, oil seals of service valves often begin to leak.

If the air conditioner still needs to be removed, before starting work, its outdoor module must be treated with a building hot air gun. Then, until the temperature has dropped, it is necessary to unscrew the plugs and close the service valves - this will save part of the refrigerant located in the outer part of the device. After that, the device is carefully unscrewed from the nozzles, allowing the remaining freon to flow out. The remaining stages of disassembly are carried out in the same way as at normal temperature.

When dismantling an air conditioner in cold weather, professional workers use manometric stations to extract freon, but buying or even renting them will cost more than the services of the craftsmen themselves. Therefore, if the preservation of all refrigerant is a fundamental issue, you will need to wait for warm weather to remove the device yourself.

We are often asked to go to another place. We can either block the air conditioner, as well as the whole. Here are typical situations when such a service is needed:

redevelopment
We decided to move the air conditioner to another room
Gathered to glaze the balcony, but the air conditioner interferes
The air conditioner must be moved so that it does not blow
The air conditioner interferes with putting up a closet, making a stretch ceiling, etc.

We will check the air conditioner before we remove it, and guarantee that will not damage it when reinstalling. The master will distill all the freon into the outdoor unit, and upon completion of the work, he will pump out the air with a vacuum pump and refill the system with freon.

If you need to build up the tubes, the installers will solder the pieces of the desired length using a special torch. Sometimes it is necessary to shift the interblock route in a different way, drill additional holes, install elongated brackets... All these works can also be ordered from climates.ru.

How much does it cost to replace an air conditioner?

It is as responsible to dismantle household climate equipment as it is to install it. Especially if its further use is planned, for example, when moving to another place of residence. Consider the basic rules of how to dismantle the air conditioner yourself without losing its effective performance.

Set of tools

Dismantling, as well as installation of the air conditioner, is strongly recommended to be trusted by professional installers. This largely guarantees a high-quality installation procedure, without the appearance of unpleasant consequences in both cases. But if there is no money for an expensive service, with certain skills, disassembly can be done independently.

The main point when dismantling a split system is careful, consistent observance of the basic rules that will preserve the functioning of the equipment. In many ways, special tools will be useful here that will help to disassemble with the least effort, with better quality. These include:

pipe cutter
side cutter
construction knife
Phillips screwdriver
integral screwdriver
hex socket wrenches
wrenches
adjustable wrenches
drill, screwdriver

A set of these tools is required because not many standard mounting tools will come in handy. Using the latter, it is likely to cause irreparable damage to the system, after which it will have to be changed.

How to properly dismantle the air conditioner? Safety regulations

There are certain rules, conditions that must be observed in order to protect health, equipment from breakdowns, malfunctions. Let's list them:

the cooling circuit must not be depressurized. It operates at a pressure of 15 A. With a sharp leak, there is a high probability of being hit by a very low temperature gas jet;
you can get frostbite from a jet of cold freon when it leaks;
it should be avoided when disassembling the ingress of dust, moisture into the circuit, which have a destructive effect on the system;
when transporting an outdoor unit containing freon, an explosion may occur;
during transportation, it is necessary to carefully handle the remaining pipe sections, as their damage will lead to the replacement of the entire unit;
it is forbidden to unscrew union nuts from fittings;
Care must be taken when handling the latches of the indoor unit so as not to break them.

Freon transportation

When dismantling the outdoor module, the primary task is to "pack" the freon. It is necessary to carry out this procedure with high quality, so as not to waste time and money on refueling the air conditioner. attention should be paid to the accuracy, accuracy of the transfer of refrigerant.

It is possible to reproduce with the help of a manometric manifold, or without it. This device will be able to show when a vacuum is reached in the cooling circuit. It is in this case that the second valve should be closed to “pack” the freon inside the condenser.

connect the gauge manifold to the nipple on the fitting instead of the branch pipe with the liquid of the cooling circuit (it is thinner compared to the second one, through which gas freon passes);
if the device is absent, it is necessary to start from the next point;
put the split system on cooling mode, determining the lowest temperature that the equipment is capable of according to its technical characteristics (you need to find out in the operating instructions). So the unit works for at least 10 minutes;
close the valve of the liquid pipe (thinner. It is closed with a hex key under the protective cap);
on the gauge manifold, watch the pointer until it reaches the vacuum level. If there is no pressure gauge, it is necessary to note 1 minute on the clock;
after the time has elapsed / the desired indicator is reached on the device, close the gas pipe valve with a hex wrench;
turn off the air conditioner;
put back the protective caps.

The difficult task of moving the refrigerant can become more difficult in the cold season, when the air conditioner cannot be turned on. The compressor oil thickens, its smooth operation is impossible. If the equipment is equipped with a "winter set" that allows the equipment to operate for cooling even at sub-zero temperatures, the problem is easily solved by starting the heating devices located in the compressor crankcase and drainage. After 10 minutes of warming up, you can start the climate system for cooling and pump freon, following the recommendations described above.

If there is no winter heating system, you can use a manometric station to collect the refrigerant. It is connected in the same way as the collector. Freon is distilled there for transportation.

Removing the outdoor unit. Is it possible to do it yourself?

After "packing" the coolant, you can proceed to remove the outdoor module from the mounts. How to dismantle the air conditioner with your own hands:

disconnect the outdoor unit from the mains;
if further use of the pipes is planned, they are unscrewed. Open fittings must be reliably protected from dust and moisture. In the case when reuse is not expected, copper pipes are cut off, leaving 15-20 cm of each branch from the fasteners. The ends are minted with a vice from moisture, debris;
when it is known that the air conditioner will not be used for a long time, it is recommended to fill the remaining pipes with nitrogen, thereby displacing the air, and clog it. This will prevent the oxidative reaction of the metal with atmospheric oxygen;
remove the thermal insulation from the freon circuit;
disconnect the outdoor unit from the electrical cable by removing the pre-marked terminals;
dismantle the nuts holding the module on the brackets, remove the module. It is recommended to do it together with an assistant, because the block is heavy, there is a high probability of dropping it;
place in a special box with foam or other filler to avoid mechanical damage to the body, pipe bends;
transport, store only in an upright position.

How to dismantle the indoor unit of a split system?

The indoor unit of the air conditioner is removed from the mounts only after dismantling the outdoor unit. Care must also be taken here, especially with the evaporator clamps of the equipment itself. If these elements are damaged, the subsequently re-installed unit will vibrate during operation, which will cause it to break.

How to dismantle the air conditioner yourself:

remove the front panel so that you can get to the latches;
disconnect the pipeline of the cooling circuit;
turn off the power supply;
remove the evaporator (carefully unfasten the latches closed by the lid)
press the clamps of the indoor unit, remove it from the guides;
dismantle the plate on which the indoor unit was attached;
remove the cooling circuit pipeline from the wall gates;
remove the drain pipe;
dismantle the decorative box.

Consequences of incorrect dismantling

Here are some unpleasant consequences of inaccurate dismantling of the split system:

depressurization of the cooling circuit, as a result - freon leakage. When installing equipment again, you will have to pay for refueling the system with coolant;
mechanical damage to the case of the outdoor unit, outdoor module, any parts, freon pipes, especially if they lead to depressurization of the circuit;
clogging of the cooling circuit with dust, debris, moisture ingress. Dust will invariably affect the operation of the compressor, it will soon have to be replaced due to a malfunction. Moisture is dangerous because it will oxidize the inner surface of the copper freon path, the metal will begin to corrode, which will completely disable the system;
fall of the outdoor unit from a height. It doesn't matter how high it was fixed - a fall will result in its complete replacement anyway.

How to properly dismantle the split system will tell the video

When changing residence, they often carry an air conditioner with them, after all, the equipment is expensive. To do this without loss, it is strongly recommended to contact professional installers who will do everything correctly, efficiently. If the disassembly of the air conditioner is planned on its own, it is necessary to strictly follow the rules for dismantling, while doing everything as accurately, clearly, and smoothly as possible.

Air conditioning

In connection with a change in the location of the office or with a move to a new location, it may be necessary to dismantle the split system. The process has some of its own characteristics regarding the time of year, the device, as well as the availability of the necessary tools.

Air conditioner device

Few people know the principle of operation: the compressor of the outdoor unit pumps out refrigerant vapors from the indoor unit, then they thicken, warm up well and give off heat to the environment, and evaporate through the radiator. Then it begins to absorb the air of the room temperature, thereby cooling the room. The entire cycle described above is constantly repeated.

One sensitive place can be immediately noted in the device device, this is the air conditioning pump. Working in such difficult conditions, it must be quite a massive unit. Indeed, it contains several rotors of complex configuration, closed in a sealed chamber. The necessary vacuum is carried out due to one-sided actions, which are formed solely due to the fixed accuracy of the processing of parts. Few designs can handle these pressure and temperature fluctuations.

Now you can understand why the pump is so vulnerable, because a small scratch from dust, a piece of oxide from pipes or ice and the air conditioner will waste electricity on mixing the refrigerant for nothing, and not cooling the room.

The price of the master's work

If we collect in one summary the cost for installation and dismantling of a split system, we get (on average) a fairly simple ratio: 1B - 1 rub. That is, the price of transferring a household air conditioner will cost about 2,500-4,000 rubles, and a large one that is used for an office or a mansion - 8,000-10,000 rubles. If you need to remove the cassette unit, which is mounted in a false ceiling, then the price will increase by 15%.

The cost of dismantling the split system with your own hands

Even a slightly technically equipped person intuitively understands that it is impossible to simply open the fittings, since the entire system is filled with freon inside. If this is nevertheless done, the liquid will flow out of it, and refilling it with a new one varies from 800-1500 rubles. Therefore, certain measures are needed to solve this problem.

Therefore, some installations and tools are needed. To carry out the dismantling of the air conditioner, first of all, a manometric manifold is needed. The cost of the cheapest varies from 1,500 to 3,500 rubles. This is almost the cost of the entire dismantling. It also requires a set of hex socket wrenches and a pipe cutter - about 250 rubles. That's the amount that the work will cost. Well, if you rent all the equipment, or at least partially, then the independent dismantling of the split system is quite justified.

Workplace preparation

In order for all actions to be carried out safely and conveniently, it is necessary:

remove all furniture and other property that will interfere with the working area;
when the outdoor unit is located on a wall that opens onto a balcony or loggia, it is necessary to provide full access to external equipment;
tools and equipment are placed in an accessible and convenient place for the master;
if work is carried out in cold weather, it must be taken into account that the room will be cool enough, and this should not cause discomfort to residents and pets;
be sure to prepare safety material and consider the point of its location.

Tools

When servicing and dismantling a split system, it is important to follow the basic safety rules, namely, use safety equipment and have an assistant. In order to clean the apartment air conditioner, you need to prepare the following tools:

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

Dismantling the split system with the preservation of freon

Before you start removing the device, you need to overtake the refrigerant so that it does not leak out. You need to do the following:

The air conditioner is switched to cooling mode and the lowest temperature is set on the remote control.
On the outdoor unit, you need to find several valves of different sizes and use an adjustable wrench to open the plugs.
After the compressor is started using the hexagon, the smaller valve is closed. And to the larger one, you immediately need to connect the collector.
The pressure drop is monitored on the pressure gauge. After the arrow falls below zero, the large valve is turned on.

After all these steps are completed, the air conditioner turns off and all the refrigerant remains in the outdoor unit. The last step is to disconnect the wire from the outdoor unit.

Why is freon storage important?

When the air conditioner exhausts its entire resource, it is easy to dismantle the split system without saving the refrigerant, and if not, it is better that it does not leak out. According to scientists, the consequences of such actions are significant, since the environment is harmed.

It is, of course, easier to dismantle without preserving the liquid, but after that you will have to throw the device in the trash. And the reason for this will be the almost assured failure of the compressor of the vacuum pump. The tightness of its chambers is ensured not by piston rings and gaskets, but by high accuracy of processing, as well as precisely balanced parts. Even the smallest scratch on the surface of the chamber will lead to a complete loss of performance after the secondary injection of freon and switching on.

Disconnecting communications

The dismantling of the split system is carried out in several stages. They are listed below:

A smaller tube is unscrewed, most often this process does not cause serious difficulties.
A larger diameter tube is unscrewed carefully with little effort so as not to damage the thread.
After the freon pipeline is disconnected, all valves are closed with plugs. These actions will save the external unit of the device from getting into the middle of debris and moisture. If the plugs are not available, then you can simply use the usual electrical tape.
Electrical communications are disconnected.

Removing the outdoor and indoor unit

The outdoor unit will need to be unscrewed from the horizontal brackets. Most often, this part is screwed with M8, M6 or M10 bolts. After everything is disconnected, the case is removed and set aside. On the facade of the room, only the freon outlet should remain intact, which does not need to be removed yet.

The next step is dismantling. For a beginner, this process will seem quite simple. But, in fact, in order to competently carry out all the work, it is necessary to follow a certain procedure:

Determine the design of fasteners and latches. Different models of air conditioners are able to fix the housings to the mounting plate and most often differ from each other.
Arrows are drawn at the bottom of the block, which indicate the place where the case and plate are detached. Depending on the models, it is required to press / pull or unscrew the screws at the set point. The true information can be read in the instructions that come with the kit. Manufacturers form a special latch system, since there is an evaporation block next to the mount. Various external vibrations of this part may cause a malfunction of the device. To open them, experts recommend using a special device. If it is not available, since the dismantling of the split system is carried out independently, then you can take any tool at hand that will help you do this. All actions must be careful and consistent so as not to damage the evaporator tubes.
After opening the lower part of the case, it is necessary to move it slightly away from the wall. Behind it is a freon pipeline in a heat insulator, a drainage pipe and an interconnect cable.
An electrical wire is disconnected from the inside, for this you need to unscrew the cover and remove the cable from the terminals and remove the wire from the unit.
The drain tube is removed. A small container is prepared for it in advance, since a small amount of water may leak out.
Do-it-yourself instructions for dismantling a split system say that only then can you start disconnecting the freon pipeline. To do this, you will need to disconnect several tubes of different diameters. All these communications are located behind the thermal insulator. One tube is sequentially unscrewed, and then the other. Then you need to muffle everything or rewind it with electrical tape.
After the interconnects are completely disconnected, the indoor unit is lifted up slightly and removed from the mounting plate. It is set aside, and only the mount remains on the wall.
Further, self-tapping screws are unscrewed from the plate and it is also necessary to set it aside.
In order for the fastener not to be lost, it is recommended to screw it back to the block and transport it like that.

Only the freon line remained on the facade of the building. For further proper dismantling of the split system, you will need to unscrew the nuts and remove the entire structure.

Winter time

There are some difficulties if you carry out independent work in the cold period of time. The fact is that at a temperature that is below the permissible values of the device, it is not allowed to turn on, so it is impossible to pump the working fluid. In such cases, a manometric station is needed, which will allow you to collect all the freon. Further dismantling of split air conditioner systems is very similar to the standard scheme. All taps are closed, the station is connected to them, freon is pumped. And you can start to already familiar work.

Many domestic air conditioners have a hard time getting to the latches so as not to damage them. Therefore, you have to remove the cover of the evaporator. All fasteners are directed towards the wall, but the most desperate "kulibins" get out of this position when using a Phillips screwdriver. They unscrew the fixing screws with it, holding them with pliers.

In order to install and dismantle the split system with your own hands, you need three people, as there is a risk that the unit will fall down and break.

At the time of transportation, the inside of the air conditioner can be in any position, and the outdoor unit can only be in the way it is installed on the brackets, that is, only upside down and legs down.
