WARNING Electrocution
If installing the appliance in rooms with a bath and/or
shower, take the relevant safety zone into account in
accordance with the information on the appliance type
plate. The safety zones are defined in the IEC 60364-7-
701 standard.
If a pair of appliances working in differential mode are being
installed in two different rooms in the apartment, create an air
connection between these rooms by ensuring that the overflow
air apertures are large enough.
Windowless extract air areas (e.g. kitchens, bathrooms and toilets)
should only be ventilated with the appliance if it is installed in an
external wall. Appliances should not be connected to a shaft or
pipeline.
Installation directly above ground level and in narrow pits and
light wells is only possible if the units are installed in the non-liv-
ing space (e.g. basement).
To avoid draughts caused by fan operation, we recommend in-
stalling the appliance next to windows at lintel height.
