Condensing water outlet

During the heating season, humidity of extract air condenses into
condensing water. Water formation can be abundant in new buildings
or if ventilation is low compared to the humidity build-up caused by
the residents. Condensing water needs to flow out from the ventilation
unit without hindrance. In carrying out maintenance, for instance in
autumn before the beginning of the heating season, make sure that the
condensing water outlet (L) in the bottom tank is not clogged. You can
check it by pouring a little water in the tank. Clean if needed. Do not
let water flow into electrical devices.
