The installation process of the air conditioner can be divided into two stages: preparation, that is, the choice of location, and, in fact, installation. Of course, it is important to do everything correctly, in accordance with the technical documentation.
Self-study will require certain tools. For example, a special pump is required for evacuating the apparatus. In case of lengthening of the freon line, it is necessary to increase the volume of the refrigerant.
The installation point depends on the specific type of air conditioner: window, mobile, floor or split. The area that it will cool and the interior matter. It is better not to direct it to where people often sit, that is, on sofas, desks and beds.
It is advisable to place the indoor unit as close as possible to the window sill. Distances from the ceiling, walls and floor for free passage of cold air should be respectively 15, 30 and 150 cm.
Window air conditioner
The outer module is mounted outside the window or to the right of it, but so that the sides do not close the opening. If the device is placed on the ground floor, then it is mounted at a height of not less than 3 m from the ground. The rules also require placing outdoor boxes not under the direct sun and in places well blown by the wind.
Floor-mounted air conditioner
The placement of indoor and outdoor units should be optimal in terms of the freon line and hose condensate drain. To do this, consider the thickness and material of the facade walls.
The amount of refrigerant according to standards is calculated for a line of 5-6 m. At longer lengths, coolant is added to the system.
On the other hand, the minimum allowable length is 1.5 m. If the back-to-back modules are suspended, dividing only by the outer wall, the route will have to be increased to the required size, laying a loop behind the outer duct of the air conditioner . It is necessary to dampen the vibration and noise from the operating device.
Installation of the air conditioner
In the first case, you need a vacuum pump and a high pressure hose. One end is connected to the pump, and the other - to the spool of the gas port. To make it clearer, take a look at the picture:
1 - port of the liquid pipe; 2 - port for a gas tube; 3 and 4 - valves with protective caps; 5 - spool for refilling and bleeding freon.
The pumping process will take 5-7 minutes, depending on the length of the track.After that, you need to open the valve number 4 for the intake of coolant and immediately close it. Part of the freon will flow out. This method is the only available if the length of the pipes is more than 6 meters and there is no possibility to fill the air conditioner with a coolant.
With a short route, you can try another method that does not require a vacuum pump. It is necessary to blow the air out of the line with the liquid. To do this, unscrew the caps of the valves number 3 and 4, as well as the valve № 5. Valve number 4 must be rotated 90 ° for a few seconds to let in some freon, and then shut off. Now, clicking on the valve number 5, you need to release the mixture of refrigerant and gas almost completely. Almost - because part of it must remain and prevent the ingress of outside air.
After removing the moisture, you must fully open the gas and liquid valves and check the tightness of the connections by covering the joints with soapy water.
