Modern air conditioners have a rather complicated design, in which all the elements operate in a chain relationship with each other. A malfunction of any link entails a malfunction of the entire device. That is why when dismantling it is necessary to strictly observe the technological sequence. Possible costly losses require the involvement of qualified personnel, so the cost of dismantling the air conditioner may seem high.
Tools for dismantling the air conditioner
If you want to save money, you can dismantle the air conditioner yourself, for which you will need a standard bench tool:
- Wrenches 8-14 mm.;
- Hexagons 7-12 mm.;
- Adjustable wrench;
- Figured and straight screwdrivers;
- Knife;
- Pliers;
- Hammer;
- Insulating tape.
So that the price of dismantling the air conditioner does not increase due to unforeseen losses, it is necessary to keep the refrigerant in the system to ensure the possibility of restarting after subsequent installation in another place.
If the refrigerant leaks out, it can cause serious injury if it gets on your hands or other parts of the body. Since the working fluid is under high pressure (more than ten atmospheres) with a sharp expansion, its temperature decreases about minus thirty or more degrees, which is fraught with frostbite.
To make up for the loss of refrigerant, you will have to turn to the services of specialists; it is impossible to pump it yourself. The download service will cost more than the cost of dismantling the air conditioner, so in case of unforeseen losses of the refrigerant you will have to forget about the savings. Therefore, before starting work, you need to think about whether to dismantle the air conditioner yourself. It is worth considering that in some the price of dismantling the air conditioner is quite acceptable and is not a problem.
The dismantling sequence of the outdoor unit
First of all, it is necessary to pump all the refrigerant into the outdoor unit. To do this, remove the safety caps with an adjustable wrench and close the cap on the outlet channel valve (where a thinner tube is installed) with a hex wrench. On the block, the input and output have the corresponding designations. The air conditioner is turned on in the cold mode for about one minute, during which time the compressor pumps all the refrigerant from the cooling chamber. The air conditioner shuts off and the plug for the inlet channel is blocked.
Now you can unscrew the nuts with a wrench, pressing the flared end of the tubes to the unit fittings, the order of the tubes does not matter. It is not necessary to unscrew completely, the nut must remain baited, while disconnecting the tube, one must listen to whether the plugs are poisoned. If there is any suspicion, it is better to contact a service that professionally installs and dismounts the air conditioner. If everything is normal, the tubes are disconnected, it is necessary to insulate the ends of the tubes and fittings so that they do not get dirt, the electric cable is disconnected, and the fixing bolts of the unit are unscrewed. The outdoor unit can be packaged.
On the indoor unit, unscrew the two tube nuts, isolate the ends, remove the drain pipe, disconnect the wires, the unit is lifted and removed from the wall. Thus, the installation and dismantling of the air conditioner is carried out.
