3. Press the “SET” button again. The scale will return to weight model.
Charging
1. When the programming is completed, press the “GO/ HOLD” button to start charging. A
“CLICK” will be heard as the solenoid opens, and refrigerant starts to flow.
2. The amount will start to decrease indicating the weight dispensed.
Caution: will be displayed if the charging amount is not set or the refrigerant tank is
empty.
3. If the refrigerant tank empties before the programmed charge is reached, press the
GO/HOLD key again to stop the operation.
4. Close the empty tank valve, disconnect the hose, replace the tank and reconnect to the
valve.
5. Press the GO/HOLD key again. The solenoid valve will ‘click” open.
6. When the programmed amount of refrigerant has been charged, the solenoid valve will
close and the charging mark will disappear.
7. Check the display: when the target charge or maximum allowable charge is reached, the
scale will back to weight measurement model and display the current reading.
8. If there is a need to release the refrigerant in the charging hose when the charging
procedure is over, please press the “FORCE” button.
9. When the operation is completed, close the refrigerant tank valve, the manifold valve or
the recovery machine. Press the “OFF” button to turn off the scale. Remove the refrigerant
