When the air conditioner is running, the windows and doors should be closed, and the doors and windows should be switched quickly.

(2) if the temperature in the car is high, the window can be opened before using the air conditioner, driving 2-3min, after the internal hot air is discharged, then the window is closed, and the V3 parts air conditioning is started.

(3) the air conditioner is not used for a long time (more than 1 months). The test runs a few minutes a week and the diesel engine is idle at running time. It is beneficial to the normal lubrication of the internal parts of the V3 parts air conditioner in the north.

(4) when the air conditioner works, because the cooling system of diesel engine increases the load, the high temperature of the cooling system is normal.

(5) when a diesel car stops for a long time, a medium speed or higher diesel engine speed should be selected to help cool down.

(6) before the North Run V3 accessories air conditioning is used every year in the summer, we should do a comprehensive inspection, cleaning, leak detection, or adding refrigerants to each assembly of the refrigeration system to ensure the normal operation of the refrigeration system.

(7) the refrigerant used in the diesel automobile air conditioning is R12, which is colorless and odorless gas under normal temperature and atmospheric pressure. If the concentration of the air in the air is suffocated by the general assembly, the R12 will not burn, but the toxic gas can be decomposed when exposed to the open fire. If liquid R12 touches skin and eyes, it will cause frostbite, so care must be taken.
