NOTE
A fully automatic air conditioning service is started using the "Short
selection" menu. You only have to enter the filling quantity as shown
on the label in the vehicle.
The following actions are performed automatically in succession in the
"Short selection" menu:
Performing the refrigerant analysis (see chapter "Analysing
refrigerant" on page 86)
Extraction of the refrigerant
Recycling the refrigerant (purity = SAE J 2099)
Pressure rise test
Draining the used oil
Evacuating the system
Before working on the vehicle air conditioner, a leak inspection must
be carried out. The air conditioner is filled with a sample of 50 g
refrigerant. The pressure in the air conditioner must remain constant
over a period of 5 minutes. The air conditioning unit can only be com-
pletely filled if this test has been successfully completed. The sample
filling of 50 g is then drained and the air conditioner evacuated. The
final filling quantity is completely filled up to ensure high filling accu-
racy.
Leak test / vacuum check
Filling with new oil to the required quantity
Filling with UV additive
Filling of refrigerant
After each process has been performed, a service report is printed.
Subsequent actions are only initiated once the preceding action has
been completed successfully.
1. First fit the service hoses for the AirConServiceCenter to the vehicle
air conditioning system, and open the service couplings.
2. Press the cursor key or to access the basic menu.
