3 Ensure the valve on the refrigerant canister is open. Start the charging
operation by pressing the “CHARGE” key. You will hear the internal solenoid
valve click open and refrigerant will flow. When the programmed target
charge is reached, the solenoid will close, there will be an audible beep,
and the bottom display will flash between “CHARGE COMPLETE” and the
programmed target charge value.
How to put the Charging Operation on Hold
Once the charging operation has begun, you can interrupt it at any time (put
the cycle on hold) by pressing the “CHARGE/HOLD” key once. The solenoid
valve will close and the display will flash between “HOLD” and the programmed
target charge weight. The amount of refrigerant transferred to that point will be
displayed on the top line.
Adjustments or changes to the programmed target charge can be made while
the Charging Module is in “HOLD”. Additionally, you may change your
refrigerant tank during this time. To restart the charge cycle, press the key once
and the module will continue the refrigerant transfer from the last reading.
