Tank-To-Tank Transfer
When recovering refrigerant from one refillable tank into another, the color of the
hoses used for SYSTEM LIQUID and SYSTEM VAPOR may not match the color
of the liquid and vapor valves on the tank you are pulling the refrigerant from.
Confirm the hose for SYSTEM LIQUID is connected to the liquid valve of the tank,
and the hose for SYSTEM VAPOR is connected to the vapor valve of the tank.
1. Connect the hoses in the following manner.
Standard End connects to: Ball Valve End connects to:
TANK LIQUID fitting on unit LIQUID port on tank refrigerant
is being transferred into
TANK VAPOR fitting on unit VAPOR port on tank refrigerant
is being transferred into
SYSTEM VAPOR fitting on unit VAPOR port on tank refrigerant
is being transferred from
SYSTEM LIQUID fitting on unit LIQUID port on tank refrigerant
is being transferred from
2. Follow Steps 1 through 5 in the Recovery Procedure on the previous page.
NOTE: Remember to monitor tank weight.
hIGh PressUre
If, during the recovery or self-clearing process, the HIGH PRESSURE light comes
on, verify all appropriate valves are open. If the valves are open and the light is
still on, there is an excessive amount of air or the tank is full. Follow these steps:
1. Press the COMPRESSOR switch to OFF.
2. Close both valves on the refillable tank, and close both valves on the red and
blue hoses connected to the tank.
3. Disconnect the red hose and the blue hose from the refillable tank.
4. Replace this tank with an empty refillable tank.
5. Reconnect the hoses as described in the Setup Instructions. Then follow the
steps in either the Recovery Procedure or the Self-Clearing Procedure.
If, after completing the above steps, either light is still on, call the Technical
Support Line at (800) 822-5561.
WarnInG
The refrigerant level in the tank must not exceed 80% of the tank
volume. Failure to monitor the level could result in excessive
hydrostatic pressures, causing physical injury or death.
