To initiate charging mode, press the 'UP' key three times (or DOWN once), followed by the
'START' key. Select the desired refrigerant amount by pressing the 'UP' key to increase or
'DOWN' key to decrease. The maximum refrigerant weight that can be set at this point is
determined by the actual refrigerant weight available in the unit cylinder.
(example value only)
Once the refrigerant charge weight has been set, press the 'START' key and open appropriate
hand valve depending on weather you are charging with the engine running or stationary (if the
A/C system is OFF or ON).
The display (2) will start from zero and will indicate the amount of refrigerant that has been
charged into the air-conditioning system. This function can be paused at any time, by pressing the
'STOP' key once, or twice, to cancel the function.
If the charge function has been paused, the amount of refrigerant that has been charged to that
point will be displayed, to continue the charge function press the 'START' key.
Once the present refrigerant weight has been charged, the charge function will automatically stop
and the display will indicate 'DONE'. The operator can return the machine to its initial state by
pressing 'STOP' key on the console.
Conditions that will prevent refrigerant charging:
- If there is little or no refrigerant in cylinder.
- If the cylinder valve is closed.
- If the hand manifold valve (4) console is closed.
- If the A/C system service port Schrader valve is not depressed.
