9.3.3 Filling of refrigerant, fresh oil and UV dye
i
Fresh oil and UV dye can only be added to an air
conditioning system under vacuum. A vacuum must
be generated prior to the oil/UV dye filling process.
i
If pressure is detected in the vehicle air
conditioning system during filling, recovery must be
implemented in order to continue.
i
Fresh oil and UV dye can only be added in
conjunction with R134a.
!
Always observe the vehicle manufacturer's
instructions before altering the oil quantity.
!
Before filling with UV dye it is essential to check
whether leak testing of the air conditioning
system with UV dye is approved by the vehicle
manufacturer.
!
Filling should, if possible, only occur via the high
pressure connection. For systems that have only
one low-pressure connection, at least 10 minutes
must pass after filling before the vehicle air
conditioning system can be switched on.
