TANK FILLING
This operation must be performed whenever the available refrigerant fluid in the tank is less

If gas analyzer is installed, the machine will test the purity of the refrigerant gas in the external
tank before beginning recovery (refer to Gas analyzer instruction manual)
From MAINTENANCE, select TANK FILLING, the following screen will be displayed:
Procure a tank of appropriate refrigerant (R134a or R1234yf), connect and open LP coupler to
the liquid side of the external tank and open the liquid valve, then Use the keypad to insert the
amount of refrigerant, then press ENTER to continue.
