Maintenance
Located on the front side of the unit is a fluff filter (n) and a
particle filter (p) for cleaning the air in the room.
p
n
The fluff filter (n) must be cleaned at regular intervals, at least
twice a year, and replaced if necessary (part no. 40090-64600).
We recommend that the particle filter (p) be replaced annually
at the start of the season (part no. 40090-58100).
To change the filters, disconnect cold air ducts beforehand.
Pull fluff filter (n) forward slightly at recesses at upper edge
and remove from above. Then withdraw particle filter (p) from
the front.
The arrows printed on the particle filter (p) must point
towards the unit when the filter is installed – these indi-
cate the recirculated air flow direction. The device must
never be operated without the filter. Without a filter the
evaporator will become dirty, which in turn will impair the
performance of the device!
The condensation water drain is located beneath the floor of
the vehicle. In order to allow the condensation to drain away
freely, check whether the drain is free of dirt, leaves and the
like at regular intervals. If this is not done, there is a risk
of condensation water penetrating into the vehicle!
Troubleshooting
Is the motor home / caravan 230 V power supply lead
connected, and are the fuses and circuit breakers OK?
