NOTE
The

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 can-
not 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 AirCon Service Center
using special adapters to form a flushing circuit.
