3.2 Filter

The filters have a limited lifetime, and to preserve a
healthy indoor air quality it is important to change them
when they are dirty.
How often the filters need to be changed depends on the
degree of contamination in the air where they are installed.
In general, the filters need to be changed a minimum of once
a year, preferably in the autumn (after the pollen season). In
areas with a lot of dust and contamination, the filters should
be changed in the spring and autumn.
Dirty filters can, among other things, lead to:
• Reduced performance of the unit
• The unit becoming dirty
• Humidity damage in the bathroom
• Reduced indoor air quality
A filter subscription is recommended to ensure full benefit
from the system. The article number for a replacement filter
set is 110716.
To take out the filters:
1. Grip the handle and pull the filter cassette out (see Fig.15).
2. Push the filter out of the cassette (see Fig.16).
3. Insert a new filter.
NB! Ensure that the filter is not damaged during
installation. Use the filter's outer edge when you
push it in. A damaged filter reduces the unit's
effect and the air's purity.
When changing the filter, check that the whole unit is working
normally. Use the following checklist:
• Check that the rotor is rotating (see Fig. 17).
• The unit has filters both for outdoor air and extract air.
• Check that the fans are clean.
