Precautions When Charging Refrigerant

PRECAUTIONS WHEN CHARGING REFRIGERANT

1. Do not operate compressor without enough refrigerant in refrigerant cycle.

If there is not enough refrigerant in the refrigerant cycle, oil lubrication will be insufficient and compressor burnout may occur, so take care to avoid this.





2. Do not open high pressure valve of manifold gauge with compressor operating.

If the high pressure valve is opened, refrigerant flows in the reverse direction and could cause the charging cylinder to rupture, so open and close the low pressure valve only.

3. Be careful not to overcharge with refrigerant in system.

If refrigerant is overcharged, it causes trouble such as insufficient cooling, poor fuel economy, engine overheating etc.
