Avoid covering the air inlet of the air conditioner with debris and clean it regularly. 2. Regularly check whether the liquid level of the refrigerant in the air conditioning system is normal. 3. When starting the air conditioning system for the first time, you should first open the engine hood to visually inspect whether the appearance of the air conditioning system is neat, whether the compressor is secure, and the tightening force of the compressor belt. Then, start the engine, idle and turn on the A/C switch and wind speed switch of the air conditioning. Carefully observe whether the compressor is working normally and whether the air conditioning system has any abnormal noise. If there is any abnormal noise or the compressor is not working properly, immediately turn off the air conditioning system. 4. Regularly check if the compressor belt is in good condition. If the surface of the belt is in contact with the side of the pulley groove and there is a "squeaking" noise when starting the air conditioner, regularly check the air conditioning system hoses and pipe joints for oil stains. If leakage is found, it should be repaired promptly. 6. Regularly clean the condenser. Regularly cleaning the surface of the condenser can greatly improve the cooling effect of the air conditioning system. 7. Check if the compressor belt is in good condition. If the surface of the belt is in contact with the side of the pulley groove and there is a "squeaking" noise when starting the air conditioning, it indicates that the belt is slipping seriously and the belt and pulley should be replaced; If the belt is too loose, it should be adjusted, otherwise it may cause poor cooling of the air conditioning system. 8. When the air conditioning compressor is turned on, sometimes slight changes in engine performance and power can be detected. This is normal. When the air conditioning system is working, it can remove moisture from the air. Therefore, when using the air conditioning in place or after stopping, you may notice dripping water at the bottom of the engine compartment, which is also normal. 9. Therefore, it is necessary to regularly clean and replace the air conditioning filter. 10. Try to avoid frequently turning on the air conditioning to avoid damaging the compressor. The air conditioning system will automatically adjust according to the temperature set in the car. Do not manually control the 12cwto8 by opening or closing the switch. 11. It is prohibited to turn on the air conditioning in place for a long time or rest and sleep in the car. Due to the excessive carbon monoxide generated during prolonged idle operation, it can enter the car through the air intake of the air conditioning, thereby affecting the air quality inside the car. When the car is sealed too tightly, it can even threaten the lives of drivers and passengers
