!
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.
!
It is important to use a Flexit
original filter.
