Short selection

I
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 96)
 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 refrigerant.
The pressure in the air conditioner must remain constant over a
period of 5 minutes. The air conditioning unit can only be completely
filled if this test has been successfully completed. The sample filling
is then drained and the air conditioner evacuated. The final filling
quantity is completely filled up to ensure high filling accuracy.
 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.
