Refrigerant Recovery Procedure: Procedure

  1. Perform compressor oil return operation. Ref. to AIR CONDITIONER>COMPRESSOR OIL>OPERATION .
  2. Turn the ignition switch to OFF.
  3. Attach the manifold gauge set.
    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 attached operation manual.
