heat exchanger, and improves the inside environment by remove dust and particles, in both
airflows. F7 class filter can be purchased. If F7 is used, this is always placed in the supply air,
removing even smaller particles. Correct placement of F7 filters according mode selection, is
shown at page 11
Heat exchanger The counter flow Aluminum heat exchanger absorbs the heat energy from extract air and
moves this heat energy to the ingoing supply air, resulting in domestic ventilation with low
heat loss.
The supply fan supplies fresh outdoor air through the unit's heat exchanger to the ducts,

where it´s distributed to bedrooms, living rooms and possibly sauna or steam bath.
The extract air fan draws used, moistened and polluted air from house, through the unit
and heat exchanger, in which the heat is absorbed and moved to supply air. Finally the air is
exhausted to the outside.
