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.
