must be carried out before working on the vehicle air conditioner. The vehicle air conditioner is filled with a sam-
ple refrigerant. The pressure in the vehicle air conditioner must remain constant over a period of 5 min. The vehi-
cle air conditioner can only be completely filled if this test has been successfully completed. The sample filling is
then drained and the vehicle air conditioner evacuated. The final filling quantity is completely filled up to ensure
high filling accuracy.You only have to enter the filling quantity as shown on the label in the vehicle.
