9.3.1 Recovery
i
During the recovery phase, ACS 810 automatically
empties the service hoses and separates the
extracted oil from the refrigerant which flows into
the used oil bottle.
i
The pressure in the vehicle air conditioning system
must be checked prior to and during the recovery
phase.
i
It is recommended to let the air conditioning system
run for a few minutes before the recovery. This will
allow a larger amount of refrigerant to be extracted.
Turn off the air conditioning system before starting
recovery.
