NOTE
The
“Flushing”
menu is used to flush the vehicle air conditioning
system with fresh refrigerant. Flushing is especially suitable for
replacing old compressor oil or removing most metallic residue from the
system.
Before flushing, the refrigerant must first be extracted from the vehicle
air conditioning system. Afterwards the system components which
cannot be flushed must be disconnected from the refrigerant circuit (for
example the compressor or filter). After that, the components to be
flushed are connected to the service ports of the AirConServiceCenter
using special adapters to form a flushing circuit.
