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 car window can be opened before the use of the northern Baotou Benz accessories air conditioner, and the driving is 2-3min. After the internal hot air is discharged, the window is closed and the 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 northern Baotou Mercedes Benz accessories air conditioner.

(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 use of the Baotou North Benz accessories air conditioning every year, we should do a comprehensive inspection, cleaning, leak detection or adding refrigerants to the 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.
