FILLING THE MACHINE BOTTLE
This operation must be performed whenever the available refrigerant fluid in the bottle is less
than 3 kg and must in any case be performed when the “empty bottle” alarm is displayed.
Procure a bottle of R134a or R1234yf (depending on machine model) gas and connect the
liquid side coupling of the external bottle to the high pressure hose (if the external bottle is not
supplied with a liquid side coupling, upend it to recover liquid refrigerant). Open the tap of the
external bottle and the HP/LP tap of the
machine . If the external bottle is not supplied with a
suction device, turn it upside down to obtain a higher delivery rate.
From the MAINTENANCE MENU:
Select BOTTLE FILLING and the following screen is displayed:
Set the quantity of refrigerant to be transferred to the machine bottle (the quantity must be
between the limit values suggested by the machine) and press START to confirm:*
