Maintenance
System maintenance by users is mainly limited to regularly changing the coarse particle fi lters
in the ventilation module and the fi ne particle air fi lter in the outside air unit. The operating unit
provides regular fi lter change notifi cations as the system operating hours are counted in the
background. A reminder to change the coarse particle fi lters is displayed approx. every 60-180
days, according to the managed nominal air quantity (depending on the environment and the fi lter
class). The fi ne particle air fi lter only has to be changed approx. once or twice a year. As the fl ow
capacity and acoustic level generated by the compact unit are affected by the amount of dirt in the
fi lters, we recommend that fi lters are changed regularly. No tools are required.
Caution: Possible damage to the unit resulting from dust and contamination. The coarse
particle fi lters in the unit not only improve your air quality, but also protect the entire ven-
tilation 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 Instructions for Filter 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 time (construction dust). In this case, no error message is displayed.
Caution: Filters cannot be washed or vacuum cleaned as this would drastically affect
their functionality. Contaminated fi lters must always be replaced with clean fi lters. Filters
should be disposed of in the residual waste.
Caution: For uninterrupted operation of the ventilation unit, we recommend that the
system is serviced by an authorised service partner after two operating years. Local
laws and regulations governing maintenance intervals and procedures must be ad-
hered to.
Changing Coarse Particle Filters
Do not switch off the device or unplug it from the mains as the controller will not detect the change
of fi lter.
Open the ventilation module's inspection cover.
The cover is held in place by latches and can be removed at the recessed grip. With a slight
tug, without any tools, the cover latches can be released.
b
Remove both fi lter cartridges.
