Fig. 4.1 Required minimum distances/installation free spaces
– The attached condensed water drain trap is destined
to compensate pressure between the device and the
installation room, for that reason it must always be
filled with clear water.
– For hygienic reasons, it must not be directly connect-
ed to the odour trap of the waste water system. En-
sure an air gap of at least 20 mm.
– For the installation, at least 10 cm of free space on the
side of the device must be provided.
– For installation, filter replacement and maintenance
works, about 1 m working space in front of the ventila-
tion unit is needed. Over and beneath the device at
least 30 cm are required (see also fig. 4.1).
– If the domestic ventilation unit is mounted on an inter-
nal wall, do not select a location directly above bed-
rooms due to possible sound transfer. Always choose
a location above a non-occupied room such as a hall
or bathroom.
– With wood-joist ceilings or similar you can provide ad-
ditional sound insulation by adding insulation between
the joists.
– Always ensure that the condensation water drain is
free running.
– To avoid annoyance by excessive noise select a
sound-absorbing hose for final connections from the
unit to the air outlets.
– Install a silencer. This will help to neutralise possible
noise transmission between the unit and the air duct-
ing and reduce annoyance by noise.
– Keep the air supply inlet at a sufficient distance from
discharge air, exhaust air and drain ventilation. Com-
ply with the legal building rules and regulations.
– When installing the fresh air input and discharge air
ducts you will have to ensure sufficient separation to
avoid that the discharged air being re-circulated into
the fresh air input.
According to VDI 6022 the minimum separation is
10 m.
4.2.2 Installation Site of the Remote Control
– The remote control must be mounted such that there
is enough space around it to complete the electric wir-
ing as well as easy operation of the control.
– The remote control must be installed inside the living
space in an easily accessible place. For further details
see section 4.8.

The unit is equipped with a frost protecting sensor.
This sensor measures the temperature of the discharge
air. The fresh air fan is switched off if the discharge air
temperature falls below 3 °C.
Once switched off, the fresh air fan is only switched on
again when the discharge air temperature has risen
above 8 °C.
