4.2. CHANGING THE FILTERS
The lters have a limited life, and to preserve a healthy
indoor air quality it is important to change them when
they are dirty.

It is important to use a Flexit
original filter.
If you use a lter other than a Flexit original lter,
the ventilation unit may not work as intended. Flexit
therefore accepts no liability for any operating faults.
!
Change both filters (supply air and
exhaust air) at the same time.
!
Make sure that the filter is not
damaged during fitting. A damaged
filter reduces the unit’s power and
air purity.
!
Check that the filter’s seal is intact
before inserting the filter.
Then push the filter properly into
place to prevent air leakage.
!
CAUTION! The unit must not be
used without a filter.
!
Clogged filters may reduce heat
recovery in the ventilation unit and
cause humidity damage.
Please note that a complaint may be rejected if you use
