HVAC SYSTEM (HEATER, VENTILATOR AND A/C) > 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.

1. Perform the compressor oil return operation.

2. Stop the engine.

3. Make sure the valves on low-/high-pressure sides of manifold gauge set are fully closed.
