These data are often found on the engine
compartment plate or on the technical
manuals.
As to oil quantity technical manuals of
cars, systems as well as available details
in general indicate the total quantity of oil
in the system.
Indeed the amount of oil to be charged is
that extracted during the refrigerant
recovery phase which is very small. In the
car A/C system you have to add only the
oil amount necessary to restore the
amount set by the car manufacturer
FEATURES
Your new A/C service station is equipped
with new E³ CONNECT quick couplers.
These new couplers offer the following
functions:
1. Avoid dispersion of the refrigerant,
allowing the recovery by the tool
(thus protecting the environment and
saving refrigerant).
2. Automatic leak test of the car A/C
system valve at the end of the
service.
After connecting the quick couplers to the
(high pressure) HP and (high pressure) LP
connectors of the vehicle, screw the

of If the station detects non-condensable
gas in the tank, it will automatically run
the
procedure.
Running this procedure is very important
to ensure the ideal working parameters
for the station operation. The presence of
non-condensable gas in the tank will
increase the pressure inside the tank and,
therefore, will slow down and reduce the
efficiency of charge cycle on the vehicle.
The procedure will take a few minutes,
and its duration may vary according to
the amount of non-condensable gas
within the tank.
