Maintenance

Maintenance of your comfort ventilation system is mainly limited to changing the coarse particle
fi lters and the fi ne particle air fi lter in the ventilation unit.
The operating panel shows when a coarse particle fi lter needs to be changed. However, this is
not shown for the fi ne particle air fi lter, which needs to be changed at a fi xed time each year; for
example, at the start of the heating period.
The fi ne particle air fi lter needs to be changed once or twice each year, depending on the fi lter
type and environment. You should also make a note of the date on which the fi lter change was
carried out.
The fl ow capacity and acoustics of the ventilation unit are affected by the amount of dirt in the
fi lters. We therefore recommend that fi lters are changed regularly. No tools are required.
Caution: Possible damage to the unit resulting from dust and contamination. The coar-
se particle fi lters in the unit not only improve your air quality, but also protect the entire
ventilation system. The system must not be operated without a coarse particle fi lter.
Note: The fi lter should be changed within 2-4 weeks of the 'Filter change' message
appearing..
Safety notes for fi lter changes
Caution: The fi lter change intervals are only valid for a completely run-in system. After
the initial commissioning, the fi lters can sometimes become very dirty after a relatively
short period of time (construction dust). An error message is not displayed in this case.
Caution: Filters cannot be washed or vacuum cleaned, as this would drastically af-
fect their effectiveness. Contaminated fi lters must always be replaced with clean fi lters.
Used fi lters should be disposed of in the residual waste.
Caution: To ensure that the ventilation unit continues to operate correctly, we recom-
mended that a service is carried out by an authorised technician after two years of
operation (check the fans, clean the air module). Local laws and regulations governing
maintenance intervals must be adhered to.
Changing the fi lters
Do not switch off the unit or unplug it from the mains as the controller will not detect the change
of fi lter.
Open the latches for the inspection doors on the top of the unit.
When the inspection doors are opened, the contact switch (4) is activated and the unit swit-
ches off.
To change the coarse particle fi lter, remove both fi lter slots
(See the fi gures on the following page; no. 1 + 2).
