3.3 Replacing the brush strips
The brush strips become worn over time. If they do not
sit tightly against the rotary wheel-type heat exchanger,
it can be necessary to replace them
(art.no. 110894).
Alternatively, they can be moved closer to the rotor, where
the aluminium profile they are mounted in has two grooves.
Do the following:
1. Pull the rotor a little way out (see Fig. 18).
2. Unplug the quick-release contact fastened to the rotor
(see Fig. 19).
3. Pull the rotor out completely.
4. Remove the screw in the centre of the aluminium profile
and pull the profile out (see Fig.20).
5. Pull the brush strips out of the groove. Move them up
from level 1 to level 2 (see Fig. 21), or replace them with
new ones if they are completely worn out.
