NOTE:
- Hoses should have shut-off devices or check valves within 305 mm (12 in) of the hose end to minimize the introduction of non-condensable gases (air) into the recovery station, as well as to minimize the amount of refrigerant released when the hoses are disconnected.
- Follow the equipment manufacturers procedures and instructions.
