New Oil Bottle Filling - MAHLE ACX150 Manuel D'utilisation

Let us consider as first filling the one
carried out during the initial 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.
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
quantity of refrigerant, the unit will stop
and ask the user to close the external
refrigerant tank. Then, the device will
continue the recovery from the hoses and
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.

New oil bottle filling

To fill the new oil bottle (Fig.1 Pos. 7) it
has to be extracted from its housing by
means of the quick coupler on the top of
the bottle; slightly press downward the
coupler ring nut to extract it.
Fill the bottle by paying special attention
to the "oil care" valve.
This valve is made of a silicon polymer
membrane; it compensates
variations within the bottle and stops
humid air infeed inside thus preserving
the new oil inside.
After filling, close the bottle and place it
back in its seat.
