Air duct marking
Most units with a rotary heat exchanger also have a fifth branch (labelled E) to connect an additional exhaust duct (see
1.3. section). The air flow through this opening is delivered directly to the exhaust fan, bypassing the heat exchanger, there-
fore, you can connect ducts from the bathroom, toilet or kitchen without worrying that odours and bacteria will contaminate
the rotary heat exchanger or be passed on to the supplied air flow. However, air is extracted through an additional branch
without recuperation, thus reducing the efficiency of the heat exchanger. For this reason, we do not recommend using the
extra air extraction continuously. An additional exhaust duct should be fitted with air closing damper (motorized are recom-
mended) and should only be opened when additional extraction is required (e.g. when bathing). If the additional branch is
connected to the kitchen hood with an integrated closing damper, an additional damper is not needed.
