7.3 Initial verification
Execute the following actions in sequence by following the
display guided procedure and the illustrations on the
of the equipment:
•
Gas weight verification
•
Oil weight verification
•
First vessel filling
It is possible to interrupt the initial verification, the station
will propose at next powering to continue.
The equipment cannot operate until all the steps of
initial verification have been completed.

check with internal tank of the equipment free of refrigerant and
containing air.
Set the quantity of refrigerant to fill (at least 3 kg) and follow the
guided procedure shown on the display.
Check that the equipment hoses are not connected and positioned
in the hose winder. Start the procedure that initially implies the
creation of vacuum in the internal tank. This phase will take 15
minutes and will act on the whole equipment.

When the message occurs open the coupler by turning the knob
clockwise. Open the valve on the external tank.
Just right before reaching the planned quantity of refrigerant, the
unit will stop and ask the user to close the external refrigerant tank.

There may be two types of source tanks: with plunger and without
plunger.
Tanks with plunger shall remain upright to be able to transfer liquid
refrigerant; for this type of tanks connect to the L (liquid) coupler.
Tanks without plunger have only one valve, so they must be turned
upside down to transfer the liquid refrigerant.
The LP gauge indicates the pressure inside the external tank.
After some minutes the unit will automatically end the function.
At the end the weight of the charged refrigerant will be displayed.
