If you use water in cleaning the unit or its parts, do not let it flow into
electrical devices.

3.4. Condensing water

During the heating season, humidity of extract air condenses to water.
Water formation may 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
connection with maintenance, e.g. 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 may check it by pouring a little water
in the tank. Clean if necessary. Do not let water flow to electrical devices.
