Recovery of Refrigerant

Prevention of refrigerant release and excessive quantities.

Refrigerant (CFCs) for automobile air conditioning is believed to cause harm by depleting the ozone layer which helps to protect us from the ultraviolet rays of the sun. Therefore, it is necessary to prevent release of refrigerant to the atmosphere and to use the minimum amount when servicing the air conditioning.





1. Use recovery machine to recover refrigerant. When discharging refrigerant from the system as follows, use a recovery machine to recover the refrigerant.

- Before replacing parts on the refrigerant line.

- When moisture or air gets in the refrigerant line.

- When excess refrigerant is charged.

NOTE:

- When handling the recovery machine, always follow the directions given in the instruction manual.





- After recovery, the amount of compressor oil removed must be measured and the same amount added to the system.





2. Use charging hoses with stop valve when installing manifold gauge set. To prevent release of refrigerant, using charging hoses with a stop valve when installing the manifold gauge set to the service valves on the refrigerant line.

3. Tighten connecting parts securely.
