Flushing the refrigeration system
Before the flushing process, the refrigerant must be recovered from the cooling
system.
In case of mechanical damage to the compressor:
To protect your A/C service unit, the refrigerant must be recovered via the low
pressure connection. This ensures that most contaminants remain in the
cooling system and do not enter the service unit.
For refrigerant oil residues:
To remove the refrigerant oil before flushing, the refrigerant should be reco-
vered through the high pressure connection. If possible, the cooling system
should be run for a few minutes before recovery. This ensures that a higher
amount of oil in the cooling system is already being sucked out and does not
need to be removed by flushing.
Proceed as follows:
➤ Connect the A/C service station with the cooling system and dispose of the
coolant of the cooling system completely.

NOTE
For the flushing process, components must be dismantled and bridged with
adapters in order to ensure optimum flow during flushing.
Hoses or components that cannot be integrated into the flushing circuit have
to be replaced or cleaned manually.
