6.3.1 Cleaning the heat exchanger and the
ventilation unit
 Switch off the mains fuse at the fuse box.
Position a visible warning notice at the fuse
box to avoid the unit being accidentally
switched back on.
 Release the 2 quick-release clips and open
the front shutter.
 Remove the front cover (6 screws).
 Pull the heat exchanger carefully out of the
ventilation unit. To do this, pull with one
hand using the pull strap [1] while
supporting yourself on the ventilation unit
with the other hand.

 Do mot move the ventilation
unit, especially if it is wall-
mounted.
 Make sure that the heat
exchanger doesn't twist as
it is pulled out/in.

luke-warm water. Leave it to dry out
completely.
 Wipe the inside walls of the ventilation unit
out with a cleaning cloth.

carefully into the housing as far as it will go
(see the sticker on the front side, that
indicates the position).

the two quick-release clips.
