9.3 Manual service

¶
Firmly connect the service quick-release
couplings to the service hoses.

¶
Wear protective gloves.
!
The service parameters (vacuum generation time,
recharge quantity and oil type) can be found in the
owner's manual or the vehicle repair manual.
i
With the ACS 652 all service phases can be per-
formed manually.
i
Individual service phases are linked as standard
to other service phases as they are needed to fully
implement the individual operation selected.
i
R134a can only be added to an air conditioner under
vacuum. The vacuum phase must therefore be imple-
mented before filling with R134a.
i
Observe the vehicle-specific information before
altering the quantity of oil.
9.3.1 Recovery
i
During the recovery phase, ACS 652 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.
