1.6. Compressor type KVX
Make the first oil change at the first maintenance of the vehicle. Then approx. every 3 years. At
every oil change the oil suction strainer has to be cleaned. Observe the oil quantity according to
the compressor type (see chapter:
1.1
).
1.7. Return air grid
Clean the return air grid in the passenger area
monthly
,
in case of enormous dirt weekly
.
1.8. Condenser coil
Always keep condenser coil fins clean. Severe soiling cause’s excess pressure within the a/c-unit
system and it automatically stops working
.
Attention:
The condenser coil fins have to be cleaned with compressed air at least once a
year, in case of severe soiling more often.
