FILLING THE MACHINE TANK

This operation must be performed whenever the available refrigerant ﬂuid in the tank is less than 9 lbs (4.8 kg) and must be performed when the
“Empty Tank” alarm is displayed. Recommended capacity is between 10 and 15 lbs. Obtain a tank of R134a. Connect the tank adapter ﬁtting
(69788-332) to the R134a tank. Then, connect the high pressure hose from the tank to the high pressure valve on the machine. Open both the valve
on the external tank and the high pressure valve on the machine. If the external tank is not supplied with a liquid valve, turn it upside down to obtain
a higher delivery rate.
Switch the machine on. The MAIN MENU will appear after a few seconds:
