3. Safety instructions and warnings │ UK
A fan that is not installed correctly
may result in non-intended operation
or impermissible operation. Operation
is only permitted with a correct installation
position (see "TOP" on unit), with mounted
design cover and outer protective grille.
The fan may be operated only if the protec-
tion against accidental contact with the
impeller is guaranteed to be in accordance
with EN 13857.
Risk of injury and health risk in the
event of changes or modifications
or if components which are not
permitted are used. The unit may only be
operated with original components. Changes
and modifications are not permitted and
release the manufacturer from any guarantee
obligations and liability, e.g. if the unit is
drilled at a point which is not permitted.
Danger of injury when working at
heights. Use appropriate climbing aids
(ladders). Stability should be ensured, if
necessary have the ladders steadied by a
2nd person. Ensure that you are standing
securely and cannot lose your balance and
that there is no one under the unit.
Risk of death from carbon monoxide
when operating with air-ventilated
fireplaces. When operating with air-
ventilated fireplaces and in "air extraction"
installation position, a sufficient fresh air
supply must be ensured. The maximum
permitted pressure difference per living unit is
4 Pa. The consent of a professional chimney
sweep is needed in all cases.
Danger of electric shock from
operating with the unit not fully
mounted. Before taking off the
electronics cover, shut down all supply
circuits (switch off mains fuse), secure
against being accidentally switched back on

operate the fan when it is completely
installed. Do not commission a damaged unit.
