If the air conditioner in winter is not used for a long time, the filter should be cleaned to prevent dust accumulation from affecting the next use. If the filter has too much dirt, it can be washed with water or neutral detergent, but it should not be washed with hot water above 50 °C or strong alkali such as washing powder, gasoline, banana water or acidic liquid to avoid deformation.
When cleaning the panel, be careful not to use too much force. If the dirt is heavy, you can use a neutral detergent diluted with water. Unscrew the water from the cloth first, then wipe it. After cleaning, wipe the detergent on the cabinet thoroughly.

If the condenser and the evaporator have more dust attached to affect the exchange effect, try not to wash it with water at will. When entering the compressor, it is best to have a professional technician clean it. Since the indoor unit is not used for a long time, it is also necessary to clean the filter and the machine casing. The merchant also reminds the user to read the manual in detail before heating, to confirm that the remote control battery is fully charged, and whether the test machine is running normally. If the sound is abnormal, notify the professional technicians in time, and do not force the machine to run.
