1. Pre-cleaning:
First, turn off the main power supply of the air conditioner, and wipe the surface of the air conditioner shell with a cleaning cloth to remove dust and impurities. Then clean up the accumulated dust and foreign matter with the air duct that blows the air conditioner.
2. Main cleaning:
The main cleaning is generally divided into surface cleaning and internal cleaning:
(1) surface cleaning:
Spray a special cleaning agent, wipe the air conditioning surface and the ash filter screen with a soft brush, remove dirt such as dust and oil stains according to time, and then clean the cleaning agent and dirt with water.
(2) Internal cleaning:
Open the rear cover or pipe of the air conditioner and clean the internal compressor, motor, electric cabinet and other components. Clean with detergent, and be careful not to let water droplets enter the motor and electric cabinet to avoid short circuit. Finally, wash the inside and outside with water.
3. After cleaning:
After cleaning, use an exhaust fan to exhaust the moisture and steam inside and outside, and use a large fan to dry it regularly or in places that are easy to be polluted. After completely drying, assemble all the components and reconnect the power supply.
In short, when cleaning the central air conditioner, special attention should be paid to the use of cleaning agents, operating specifications, electricity safety and so on. Only reasonable and standardized cleaning can maximize the cleaning effect of air conditioner, ensure the normal operation of air conditioner and effectively extend its service life.
