•
Gas weight check (check of scale zero deviation after transport and tare weight reset)
•
Oils weight check (check of scales zero deviation after transport and tare weight reset)
•
Pressure check (Reset of relative pressure in relation to the local atmospheric pressure; a tank
recharge coupler, supplied with the equipment, must be used)
•
First tank filling (it requires a refrigerant gas tank with specific coupler for the tank recharge
supplied with the equipment)
It is possible to interrupt the initial check and print a report with the equipment printer in which the
checking status is reported.
5.1.8.1 First tank filling
CAREFULLY ABIDE BY THE FOLLOWING
INSTRUCTIONS TO AVOID DANGER TO
PERSONS, THE DISCHARGE OF
REFRIGERANT IN THE ATMOSPHERE
Let us consider as first filling the one carried out during the initial check with internal tank of
the equipment free of refrigerant gas and containing air.
Set the quantity of gas to fill (at least 3 kg; 2 kg minimum) 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 foresees the creation of vacuum in the internal tank.
Only when the message appears to connect the recharge tank, connect the HP quick coupler
(red colour), of the unit to an external R134a refrigerant gas tank using the supplied
adaptor.
Open the coupler by turning the knob clockwise. Open the valve on the external tank.
There are 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 HP gauge shows the pressure level into 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.
5.1.9 Containers filling
5.1.9.1 New oil container filling
The new oil container is on the left, looking at the equipment from the front.
To fill it, it has to be extracted from its housing by means of the quick coupler on the top of
the container; slightly press downward the coupler ring nut to extract it.
