Notice:
If the engine speed exceeds 2,000 rpm, the a/c compressor may be damaged.

If there is not enough refrigerant in the refrigerant system, oil lubrication will be insufficient and compressor burnout may occur. Necessary care should be taken to avoid this.
Open and close only the low pressure valve. Opening and closing the high pressure valve could cause the charging cylinder to rupture.
If the refrigerant is overcharged, it causes problems such as insufficient cooling, poor fuel economy and engine overheating.
Notice:
This may damage the inside of the compressor.
