REMEMBER!
Clean the filters at least twice a year. Set the
maintenance reminder interval as needed. See
Section 3.3.21. (The setting depends on the
cleanliness of outdoor and indoor air).
When cleaning the filters, it is also advisable to check the cleanliness of the heat recovery
cell (C) every two years or so. Grab the ears at the ends of the cell and pull the cell out
of the unit. If the cell is contaminated, soak it in a solution of water and washing-up liquid.
Rinse the cell clean with a jet of water. When all the water has drained from between the
laminas, push the cell back so that the seals next to the sliding surfaces are in place and
the "up" sticker at the end of the cell points to the corner next to the upper support.

Maintenance instructions
4.1. Filters
When the maintenance reminder or filter guard lights up the indicator
lamp, check filter cleanliness. Outdoor air is filtered in the unit with two
kinds of filters. A G3 class coarse filter (A) filters off insects, heavy pollen
and other dust. An F7 class fine filter (B) filters off fine dust invisible to the
eye. Extract air is filtered with a similar G3 class filter as outside air.
Clean the coarse filters (A) by e.g. vacuuming them 2 to 4 times a year
and whenever the maintenance reminder or filter guard. indicates a need
for maintenance. When you open the door of DIGIT2 SE, the security
switch (T) turns voltage off. The filters can also be washed with +25…30
°
C warm water and washing-up liquid, pressing them smoothly. Do not
handle the filters with force. When washing is done properly, filters stand
cleaning a few times. In other words, you have to
replace them at least once
a year or when needed
.
The fine filter (B) is not washable. Clean it at the same time as the G3 class
filters by vacuuming it with a brush nozzle. When cleaning, be careful no
to break filter material.
To ensure good supply air quality, replace the filter when
needed, at least at one-year intervals
, depending on local air quality. It is
recommended to replace filters in autumn. This way the filters stay cleaner
through the winter and can effectively filter off dust in the following spring.
