firm.
This enables you to ensure the operational reli-
ability of the plant at all times!
Filter cleaning
The unit is equipped with an air filter. This can be
withdrawn from the rear of the unit. The filter must
be cleaned at regular intervals. Clean the air filter
at intervals of no more than 100 operating hours.
Reduce this interval in the case of heavily contami-
nated air.
Please proceed as follows in order to clean the
unit:
1.
Switch the unit off and pull out the power
plug.
2.
Pull the filter out of the unit (Fig. 15)
3.
Clean the dust off the filter. Use a vacuum
cleaner in the event of slight soiling. (Fig. 16)
4.
In the case of heavy soiling clean the filter
carefully in lukewarm water. (Fig. 17)
5.
Subsequently allow the filter to dry in the air.
6.
Insert the filter back into the device.
7.
Ensure that the filter is dry and undamaged.
NOTICE!
Never operate the indoor unit without the orig-
inal filter. The heat exchanger fins on the
indoor unit with soil up if operated without a
filter and the device will suffer performance
loss.
