Practical advice
Scopes of maintenance for the air-conditioning system
The maintenance program is ended
automatically after approximately 5
minutes and the LED in Smog but-
ton (7) stops flashing. The only way
to interrupt the program prematurely
is to switch off the engine (ignition
starter switch OFF).
Note:
To ensure that the slide ring seal on the
compressor crankshaft does not dry out
and start to leak, the air-conditioning sys-
tem must be operated at least once a
month (even in the cold season).
Note:
The maintenance program for the com-
pressor cannot be carried out unless the
outside temperature is above 0 °C and
the coolant temperature (engine circuit) is
above 50 °C.
Checking the oil level in the
refrigerant compressor
M83_00-0106-01
Check the inspection glass on the re-
frigerant compressor when the com-
pressor is running (after approxim-
ately 10 - 15 minutes). The oil level
should be between the marks (min.
and max.).
Note:
Refrigerator oil is circulated together with
the refrigerant in the entire refrigerant
system. For this reason, the oil level may
differ with each check but must still be
between the min. and max. marks on the
inspection glass. Have underfilled refriger-
ator oil topped up only by the authorised
specialists of an OMNIplus Service Part-
ner.
Note:
To ensure that the slide ring seal on the
compressor crankshaft does not dry out
and start to leak, the air-conditioning sys-
tem must be operated once a month for
approximately 10 - 15 minutes by press-
ing Reheat button (8) on the HVAC con-
trol panel. At outside temperatures of
below +5 °C, the procedure should be
carried out indoors otherwise the system
will be switched off by the low-pressure
switch or ice sensor.
