3.0 Maintenance
If you have bought a
special pollen filter, it
should be fitted in the
filter slot to the right
(on all models) as this is
the filter that filters the
outdoor air.
3.1
Replacement
of filters
Your Danfoss Air unit was designed to assure an absolute
minimum of maintenance. Maintenance is limited to 1-2
filter replacements a year depending on the air volume and
air pollution levels in the area in which you live. In industrial
areas, and in areas with a high pollen content in the outdoor
air, the filters will be clogged faster than in a typical surbur-
ban environment.
When the unit gives the filter alarm (audible alarm from the
Air Dial + message in display)
Go to the Air unit.•
Remove the front panel. • There is no need for tools. Just lift
the panel off the unit.
Pull out the filters and inspect •
visually (if filter is only lightly
fouled/discoloured, you can
attempt to clean it, using a
vacuum cleaner equipped
with a brush. But most often
this will not be worthwhile nor
recommended).
Fit new filters and reattach •
foam covers.
Press the filter reset button on •
the front of the unit.
Observe filter replacements to get the maximum out of your
ventilation system.
Note: The fans use more power when the filters are enabled
so it is not a good idea to attempt savings here.
Standard filters and optional pollen filters (F7 class) can be
purchased from your installer.
