Refrigerant Recovery Procedure: Procedure

CAUTION:

During operation, be sure to wear protective goggles and protective gloves.
Connect the refrigerant recovery system with the manifold gauge set to discharge the refrigerant from the A/C system and recycle the gas.
When recycling the discharged refrigerant, keep service cans on hand. Because the recovery rate with the recovery system is approx. 90%, service cans are necessary to charge the refrigerant.
Follow the detailed operation procedure described in the operation manual attached to the refrigerant recovery system.
