Preparations for A/C service

!
The ACS 500 is intended to be used exclusive-
ly for type R134a refrigerant. Before the A/C
service, check in the vehicle documentation
whether this refrigerant is used in the A/C
system.
!
The ACS 500 cannot be used for servicing a
vehicle A/C system that has been repaired
with a chemical sealant. The sealant could
damage the ACS 500 and the vehicle A/C
system. Non-compliance invalidates the war-
ranty.
i
The vehicle-specific manufacturer's instruc-
tions must be read before each air conditio-
ning service.
Robert Bosch GmbH
Before servicing the vehicle A/C system, the fol-
lowing preparatory steps must always be taken:
1.
Place the ACS 500 on an even surface close
to the vehicle A/C system.
2.
Secure the ACS 500 against rolling away
using the handbrake.
3.
Connect the mains line.
4.
Depending on the vehicle's A/C system,
connect the appropriate LP/HP quick re-
lease couplings (Fig. 1; 7) to the service
connections on the A/C system.
5.
Open the valves on the quick release cou-
plings clockwise.

The current internal pressure of the
vehicle A/C system is displayed on
the low and high pressure manome-
ter (or on the low pressure manome-
ter only).
6. Turn on the ACS 500 at the master
switch.
7. Open the HP and/or LP valve.
i
On vehicles with a low pressure connection,
only open the LP valve. Before filling the A/C
system using the low pressure connection,
turn on the A/C system in the vehicle, set the
temperature to the maximum and the fan to
its highest level.

Overview of operating phases

In Automatic, Vehicle code and Manual modes,
the following phases can be performed:

Recovery/recycling phase
Refrigerant is extracted from the vehicle
and cleaned.

Vacuum phase
A vacuum is generated in the vehicle A/C
system and the system is then checked
for leaks.

Oil injection phase
Refrigerant oil is fed into the vehicle A/C
system.

UV injection phase
UV contrast medium is injected into the
vehicle A/C system.

Filling phase
A specified quantity of the refrigerant is
fed back into the vehicle A/C system.
