Air conditioning maintenance knowledge
Do not rotate the air conditioner
In summer, the air conditioner is almost in full load working state. At this time, it's better not to let the air conditioner run in tandem. At the same time, the temperature is set above 26 ℃, and it should be shut down for a period of time after five or six hours of use. After shutdown, do not start immediately. Restart after a few minutes to avoid overheating of the compressor.
Pay attention to the operation sound of air conditioner
When the air conditioner is heard to have abnormal noise during operation, such as metal collision, motor buzz, shell vibration, etc., it shall be shut down immediately to check the cause, and it is not allowed to continue using blindly, so as to avoid greater damage.
Protect the fins of condenser and evaporator
The heat sink of condenser and evaporator is made of 0.15mm aluminum sheet which is sleeved into copper tube and then expanded. It can't withstand collision. If the heat sink (rewind) is damaged, it will affect the cooling effect of air conditioner and reduce the cooling efficiency. Therefore, special attention should be paid to the protection.
Outdoor unit shall be protected against direct lightning strike
In summer thunderstorm weather, the air conditioning compressor and lightning are most closely contacted. Although many users have installed awning for it, the power of lightning cannot be underestimated. Therefore, the compressor installed outdoors should be welded with the down lead of the building or the structural column reinforcement for down lead to prevent direct lightning strike.
