Removing the air conditioner with your own hands

Dismantling of this household system is made for subsequent repair or when moving, many users simply solve the problem - they call masters from the service center. A prudent owner, who has the skills and desire, can save and do everything on her own, and we will tell you how to remove the air conditioner correctly, while avoiding mistakes and negative nuances.

Precautions

Any modern split-system to which the household conditioner belongs, consists of blocks for an internal and external arrangement. They are connected by two lines, which moves the refrigerant. The tube of smaller diameter circulates freon in a liquid state from the indoor unit to the outer one, along a thicker copper tube, it runs in the opposite direction, but in the gaseous state.

This is where problems lie that can ruin all your actions when you try to remove the air conditioner yourself.

1. As a result of improper shutdown of trunk pipelines, partial or complete loss of freon.
2. Air containing moisture can get into the tubes and the heat exchanger, which is fraught with breakage when the air conditioner is working in a new place - incompressible moisture gets into the compressor and disables it.
3. The ingestion of small particles into copper tubes when they are drawn through a wall or during improper transportation leads to a rapid system failure.
4. Particular attention should be paid to the soldered to the tubes of the thread on the thread, if they are damaged, it will require a very expensive repair.
5. Wrong disconnection of wires. If you do not put special labels on the terminals - it may lead to incorrect connection in a new place.
6. Cut too short drain tube, which removes condensate outside the outdoor unit, you doom yourself to its premature full replacement.
7. During transportation of the product to a new location, there is a danger of losing small fasteners and parts if they are not securely fixed after disassembly.

All of the above cases lead to a very expensive repair of the entire system, so before you begin disassembling the air conditioner with your own hands, study the instructions.

Training

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

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

The new filling of the entire system with refrigerant will pour out into serious financial costs:

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

In the most minimal scenario 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 with your own hands:

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

The third option gives the best effect without any losses, but many users use all the methods. Experts advise to fully preserve the refrigerant to avoid problems when installing dismantled equipment in a new place.

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, which connects the entire structure and ensures the supply and selection of the refrigerant.

Here is a schematic device of a modern air conditioner or any split system:

To turn off the air conditioner without loss of freon itself, it is necessary to transfer it to the condenser, for this, when the equipment operates in cooling mode, shut off the valve between the product and the thin diameter tube.When all the refrigerant is in a minute - it will take so much time to completely pump gas - it will be pumped to the condenser, it is necessary to shut it off thick tube valve, turning off the freon flow, and “close” it in an improvised trap.

Dismantling

Before dismantling the external unit, it is necessary to disconnect copper tubes, but in practice they are not reused, since their buildup is strictly prohibited. It is necessary to cut them at a distance of about 200 mm from the nozzle and staking the sections for complete sealing.

Attention! With long storage of the product in disassembled form, the tubes are filled with nitrogen; they ensure tightness to prevent oxidation of the inner surface.

Outdoor unit

The instruction says: after working with copper tubes is necessary remove heat insulationAs a rule, all the masters work together, one indoors and the other outside. Thus, the dismantling is faster: the partner has turned off the electricity and now you can disconnect the wires at the point of their connection, marking the terminals.

The tubes are straightened by hand, so that they pass through the holes in the wall without hindrance, and they are screwed to the end of the cable to remove it inside the room.

After that, unscrew the nuts that hold the outdoor unit on special brackets, together with the assistant, carefully remove the unit and move it inside the apartment. The last thing removed brackets from the wall of the building.

Important! The dismantled outdoor unit during transportation and during storage is located only vertically to prevent mechanical damage from shaking - it is inserted into the box, with foam from below.

Compressor

Sometimes only the outdoor unit is dismantled, for example, if it is necessary to repair only the compressor, and the indoor unit of the air conditioner remains in place. During similar operations, the internal unit of the split-system is also not touched.

The main condition is to dismantle the compressor correctly:

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

With such actions, the risk of damage to pipelines is eliminated and there is a real possibility of repairing others.elements located in the housing of the outdoor unit, if necessary.

Indoor unit

Dismantling the indoor unit of the air conditioner has its very specific nuances, without knowing which all your efforts will be useless, and in some cases careless actions can break quite delicate fasteners, for example, evaporator latches or clamps holding the unit on the rails.

To understand how to remove the air conditioner from the wall, you need to study the instruction manual, where there is a section of interest. This operation will be too difficult for many users - they will have to turn to professionals.

Remove the indoor unit air conditioning system will be obtained only after the removal of the front panel, then you still need to disconnect all electrical wiring, inlet and outlet tubes of freon. Disassemble the plexus wires must be carefully and without fuss. But this is not all testing - manufacturers have reliably closed access to evaporator latchesTo dismantle carried out only specially trained people.

The access is closed by a cover, the latches of which are quite tightly pressed against the wall - they can be reached using two screwdrivers with a very thin sting.Your partner should keep the whole block during this laborious process.

After removing the evaporator, you can unscrew mounting plate, which closes the access to the product supplying electrical wires and tubes of freonovodki hidden in a special groove inside the wall. The last to unscrew the decorative box, which runs along the outer wall to the very outdoor unit.

Disconnected wires are neatly twisted and folded in a separate box for transportation. To help domestic craftsmen have a video, how to dismantle the air conditioner on their own, without resorting to experts:

Dismantling in winter

Many users are interested in the question: how to remove the split system in the winter, when due to the low temperature it is impossible to pump the refrigerant into the condenser. 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 a heated crankcase compressor and the entire line of the drainage system, as well as a unit that slows down the rotation of the fan, then your intentions will be crowned with success. In the absence of it, you can use a special refrigerant collection stationwhich is connected similarly to the gauge manifold.

A few more practical advice: you can start self-dismantling only when you are completely confident in your own capabilities, and there is a qualified partner. Also, the presence of a special tool makes work much easier.
