Changing filter
We recommend changing the filter and cleaning the heat
exchanger once or twice per year. Remember to disconnect from
the mains before opening the front.
Open the front using a 6 mm Allen key (1). The locks are located
behind two holes in the side, and can be unlocked by turning the
Allen key anticlockwise, and locked by turning it clockwise.
The extraction filter (2) is easily accessible when the
cover is opened. Pull out the filter and replace with a
new one.
If
the
following
is
printed
on
the
filter:
"Staubluftseite/Dust Air Side", the text should face away
from the heat exchanger. If there is no printed text, the
filter cannot be fitted the wrong way round.
To remove the intake filter, unscrew the two finger
screws (3). The cover (4) can now be removed and
filter taken out.
Ensure the filter is inserted correctly when replacing
with a new one. The side which must face away from
the heat exchanger (downwards according to the figure)
has the following printed text: "Staubluftseite/Dust Air
Side". If there is no printed text, the filter cannot be
fitted the wrong way round.
Replace the cover and tighten the finger screws.
