8.1 Short selection
NOTE
I
A fully automatic air conditioning service is started using the "Short selec-
tion" 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 84)
– 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 completely 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 com-
pletely 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. Subse-
quent actions are only initiated once the preceding action has been complet-
ed successfully.
