14.1 Report exporting

In the main menu select MAINTENANCE
and press "REPORT EXPORTING".
By selecting this function, is possible to
export the report on USB Key and
manage it on PC with ACX Manager.

14.2 Internal cylinder fill

In the main menu select MAINTENANCE
and press "INTERNAL CYLINDER FILL".
Set the quantity of refrigerant to fill and
follow the guided procedure shown on
the display.
The set value is limited to avoid to fill too
much the internal cylinder.
Only when the message appears asking
to connect the charge tank, connect the
HP quick coupler (colour red) of the unit
to an external refrigerant tank using the
supplied adaptor.
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

ends when these are empty. Hence, it is
necessary to open the HP quick-coupler
and disconnect it from the external tank.
Thanks to the E³ CONNECT function, the
refrigerant - usually kept between the
cylinder fitting and the hose quick-coupler
until the end of the process - will not be
released in the environment.
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
automatically end the function.
At the end the weight of the charged
refrigerant will be displayed.

14.3 Self leak test

In the main menu select MAINTENANCE
and press "SELF LEAK TEST".
A leak test is carried out on the internal
components of ACX120/220.
This phase includes:

Hoses emptying

Vacuum test
This test allows to check the tightness of
the internal circuits of the equipment from
the solenoid valve, allowing the fluid
outflow from the internal cylinder, to the
manifold, (metallic component housing
