What should I pay attention to when installing air conditioners?

Precautions for installation of household air conditioner:

1, to ensure sufficient electricity for air conditioning operation, that is, power distribution should be reserved.

2. A separate air switch must be reserved for the air conditioner, and it shall not be mixed with household lighting electricity.

3. The hole in the drain wall of the indoor unit must be lower than the height of the indoor unit. Avoid the smooth discharge of condensed water from the indoor unit.

4. The outdoor unit should have enough heat dissipation space, and there should be no obstacles at the fan of the outdoor unit. Similarly, there should not be any blocking net on the heat exchange fin of the outdoor unit.

5. The refrigerant pipe must be insulated. The general refrigerant sleeve is only 1 meter long. If more than two refrigerant sleeves are needed to install air conditioners, the refrigerant sleeves must be properly treated (reinforced).

That is, add a small piece of refrigerant sleeve between two refrigerant sleeves, and then tie it tightly with a tie. This is ignored by many installers. If it is not handled properly, there may be condensed water oozing from this position.

6. If the inverter air conditioner is installed, or the air conditioner uses R4 10A refrigerant, it is necessary to do a good job of vacuumizing when filling the refrigerant. Because R4 10A refrigerant consists of various chemical mixtures.

If the refrigerant is added without vacuumizing, the proportion of refrigerant in the air conditioner will be affected because the refrigerant is mixed with air. This will seriously affect the refrigeration effect and the life of the compressor.

7. If the inverter air conditioner is installed or the air conditioner using R4 10A refrigerant is used, the special copper tube (commonly known as deoiling copper tube) using R4 10A refrigerant must be selected.

8. The characteristic of this copper tube is that the inner wall of R4 10A refrigerant copper tube is thicker than that of ordinary copper tube with the same diameter. Another point is that there is no oil on the pipe wall. If it is necessary to weld this kind of copper tube, the installer must weld it while filling nitrogen, and it is absolutely impossible to weld it directly.

If it is welded directly, oxides will be produced at the welding place and enter the compressor, which will lead to the compressor burning out.

9. Prevent freon leakage. The refrigeration effect of air conditioner after installation is greatly influenced by fluorine content. After the air conditioner is installed, let the installer carefully check the air conditioner connection port to see if there is any freon leakage.

10 to prevent rainwater from flowing backwards. In order to prevent rainwater from flowing backwards indoors, the indoor side of the through-wall hole of the air conditioner is higher than the outdoor side. After installation, the gap in the wall hole should be plugged with putty.

1 1 to prevent indoor water leakage. Condensed water will be produced when the air conditioner cools. It is assumed that condensed water should be directly discharged to the outside, but sometimes it cannot be discharged if it is improperly installed. So when installing, you can pour some water into the water tray of the air conditioner to test the drainage.

12 to prevent outdoor water leakage. Air conditioning will turn frost into water when heating. In order to prevent outdoor water leakage, the installer should install a water outlet nozzle and a water outlet pipe for the outdoor unit.

Yes, installation is very important. The air conditioner is installed in three points and seven points.

You think too much, be modest, it's hot, just provide tea, but it's not allowed to be formal. First of all, I want it myself
