CAP. 10 - A/C SYSTEM RECHARGE
10.1 REMARKS
The refrigerant recovery and the new recharge of a car A/C system work better if the car engine
is hot.
The service station has to be recently switched on in order to enable the possible vent of non
condensable gases and complete the initial ventilation phase.
FEATURES
Your new A/C service station is equipped with new ECO LOCK® quick couplers. These new
couplers offer the following functions:
1. Removal of the air from the fitting clearance at the beginning of the recovery.
2. Avoid dispersion of the gas contained in the dead space in the air, allowing the
recovery by the tool (protecting the environment and saving refrigerant).
3. 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 valves only when required by the messages on the tool display.
To recharge the A/C system, you have to know the refrigerant type and also the suitable type of
oil. These data are usually available in the vehicle user manual or on the engine compartment
plate. The car manufacturer specifications can be another source of information.
As to the oil amount, remember that technical data of the A/C systems and instructions usually
present in the vehicle show the total oil amount in the system. In the car A/C system you have to
add only the oil amount necessary to restore the amount set by the car manufacturer.
