Air conditioning system with refrigerant R134a - Edition 10.2014
5.5 Fill the refrigerant circuit with the A/C
service station.
• Depending on the type of the selected A/C service station,
variations can occur in the work procedure.
• The work procedure must always be carried out as described
in the operating instructions of the selected A/C service sta‐
tion.
• The volume of refrigerant oil that was drained off must again
be added to the circuit when filling.
5.6 Operate the air conditioning system af‐
ter filling
Note
If the AC compressor was removed, the free wheel must be turned
by hand approx. 10 turns on the V-ribbed belt pulley before it is
first put into service. This prevents that no damage occurs after
switching on the air conditioning system for the first time as a re‐
sult of fluid hammer in the AC compressor (if oil is present in the
cylinder of the AC compressor, it is pressed out when turning).
– Start the engine with the AC compressor switched off (version
with magnetic coupling).
– Set the AC compressor to the lowest possible performance;
operating mode "Econ" or A/C off (version without magnetic
coupling with regulating valve).
– Wait until the idling speed has stabilised.
– Switch on the AC compressor and operate the system for at
least 2 minutes at idle speed.
– If necessary, check the pressures in the refrigerant circuit with
the A/C service station.
– Switch off engine.
– Release the handwheel on the quick-coupling adapter.
– Remove the filling hoses from the refrigerant circuit.
– Screw on the protective caps once again.
5.7 Fill refrigerant into the reservoir (filling
cylinder or reservoir bottle) of the A/C
service station
• The work procedure must always be carried out as described
in the operating instructions of the A/C service station.
• A certain amount of refrigerant is recommended for filling into
each air conditioning system. In order to ensure that neither
too much nor too little refrigerant is filled in, the reservoir for
the refrigerant is standing on a scale.
WARNING
Do not overfill. A completely filled reservoir (filling cylinder or
reservoir bottle) could burst if the temperature rises, resulting
in catastrophic consequences
