Refrigerant Recovery

NOTE: Discharge the refrigerant from the system into an approved recovery unit before replacing any system component, except the clutch cycling pressure switch.

1. Ensure the manifold gauge set valves are turned OFF, (all the way to the right), then attach the manifold gauge set.
2. Ensure the center hose connection at the manifold gauge set is tight.
3. Place the end of the center hose to an approved recovery unit.
4. Open the low pressure valve of the manifold gauge set and let the refrigerant discharge into the approved recovery unit.
5. As soon as the system is completely discharged, close both the high and low pressure valves to prevent moisture from entering the system.
