CAP. 10 - A/C SYSTEM RECHARGE
10.1 PRELIMINARY OPERATIONS
The recovery and recharge operations have be carried out after the car /AC system has run for
some time; however, an excessively hot A/C system has to be avoided since the next recharge phase
could be adversely affected by high pressures.
The vehicle must not be prepared in a special way; connecting hoses have to be attached by
identifying their position.
Vehicle details necessary for the performance of the charge/recovery/vacuum cycle are the amount
of refrigerant and the type and quantity of oil. 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 recharged is that extracted during the refrigerant recovery phase
which is very small.
FEATURES
Your new A/C service station is equipped with new ECO LOCK® quick couplers. These new couplers
offer the following functions:
1. Avoid dispersion of the gas, 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 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.
