The following four processes can be run in isolation from the
“Free
selection”
menu:
Rec/Recycling phase: analyzing the refrigerant (see chapter “Analyz-
ing refrigerant” on page 25), extraction, recycling of the refrigerant,
pressure rise test, draining the waste oil.
Vacuum phase: evacuating the system, leak test/vacuum check.
Filling phase: Before working on the vehicle air conditioner, a leak
inspection must be carried out. The air conditioner is filled with a
sample refrigerant for this. 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.
Filling with fresh oil, filling of UV additive, filling of refrigerant.

connection, only high pressure or only low pressure connection
