Condensate removal

During the heating period the humidity of the extract air condenses to water. When bathing, while having a sauna as well
as when drying the laudry or with new buildings, condensate can richly build up. The condensate must must be able to
run off freely from the unit. Make sure that the condensation connection or the extension hose is pushed correctly into
the external facia and that the condensate can run off freely (decline of 0,5 % to outside wall /fig.5).
6.1

Filter change

In order to change the filters, two screws of the indoor facia must be removed. Take out both air filters and insert the new
air filters in the ventilation unit.
