POSSIBLE ERROR INDICATION:
The amount of refrigerant in the
A/C service units tank is less than

PHASE HAS BEEN PULLED).
12.4 Flushing (with optional
accessories)
After performing a lot of charge cycle or
after replacing components or parts of
the /AC circuit on a vehicle it is advisable
to carry out a system flushing.
The system washing (Flushing) consists in
purifying the vehicle cooling system
through several R1234yf/R134a
refrigerant flushes, by recovering it each
time, so that the impurities can be filtered
little by little through the additional filter.
Thanks to its specific design,
ACX150/250 automatically manage the
flushing process so that the process
becomes fully automatic.
Once the (optional) flushing kit has been
installed, as described in the instructions
included in the kit, and after selecting the
specific function for the kit being used,
start the phase.
In case of problems or errors during this
phase, a message will be displayed,
identifying the type of error.
It is possible to interrupt the phase in
progress at any time.
12.5 Hoses drain
To empty the charge hoses completely
perform the HOSES DRAIN phase.
Select in the menu the HOSES DRAIN
function. Wait the end of the procedure.

To check the vehicle A/C system status –
for instance in case there is no flow of
cold air from flaps – pressure values can
be checked.
Connect the HP - LP couplers or the
single coupler to the vehicle system.
Under the sequence guided by the
software perform the following preliminary
operations on the vehicle:
1. Turn on the A/C system
2. Set temperature at
minimum level.
3. Set fan speed at maximum
