Adapter Valve

Adapter Valve:

ADAPTER VALVE
Install the adapter valve to each of the high pressure and low pressure service valves so that air purging from the charging hose can be omitted. This also ensures that refrigerant leakage upon disconnection of the hose can be prevented.

1. Before connecting the adapter valve to the on-vehicle service valve, turn the adapter valve handle fully counterclockwise to retract the pin.
2. Connect the charging hose to the adapter valve. Turning the handle clockwise will cause the on-vehicle service valve pin to be pushed open by the adapter valve pin, thus opening the refrigerant passage.

CAUTION:
Check the packing for any sign of deterioration or cracks. If any abnormality is found, replace it with a new one.
Turning the handle counterclockwise will close the passage. Before removing the adapter valve from the on-vehicle service valve, be sure to fully turn the handle counterclockwise to shut oft the refrigerant passage.
