5 General safety instructions
DANGER Risks for children and people
with reduced physical, sensory or mental cap-
abilities or a lack of knowledge.
Unit may only be installed, commissioned,
cleaned and maintained by persons who can
safely recognise and avoid the risks associated
with this work.
DANGER Danger of electric shock from
operating the unit when not fully mounted.
Electric components are a potential source of
electric shock.
If the unit is open, all off the supply circuits must
be switched off (mains fuse off), secured against
being accidentally switched back on and a visible
warning sign must be attached.
Only operate the unit when it is completely in-
stalled.
DANGER Risk of death from carbon
monoxide when operating with air-ventilated
fireplaces.
The maximum permitted pressure difference per
residential unit is 4 Pa. The consent of a profes-
sional chimney sweep is needed in all cases.
Ensure sufficient supply air intake during opera-
tion with an air-ventilated fireplace.
WARNING Risk of injury due to suction
from the unit and rotating impeller.
Hair, clothing, jewellery etc. may be pulled into
the unit if you get too close to it.
During operation, always keep far enough away
to prevent this from happening.
WARNING Risk to health if filters are not
replaced or if there are no air filters.
Heavily soiled or moist air filters can accumulate
harmful substances (mould, germs, etc.). This
may also happen if the unit is shut down for an
extended period. If the air filter is missing, the
unit and air ducts become soiled.
Never operate the unit without air filters.
Only use original filters.
Regularly change air filter when a filter change is
indicated (LED or TimeStrip).
If the unit has not been used for a long time, al-
ways replace the air filters.
WARNING Risk 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 can-
not lose your balance and that there is no one
under the unit.
WARNING Risk of injury and risk to
health from parts which may affect the ventil-
ation system which are added or modified at a
later date.
Parts (range hood, air-ventilated fireplace etc.)
which are added or modified at a later date may
result in health risks and operation which is not
permitted. Parts may only be added or modified
at a later date if system compatibility is estab-
lished/ensured by a planning office. If using an
exhaust air range hood or air-ventilated fireplace,
this must be accepted by a regional master chim-
ney sweep.
WARNING 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 com-
ponents. Changes and modifications to the units
are not permitted and release the manufacturer
from any guarantee obligations and liability,
e. g.
if the housing is drilled at a point which is not
permitted
.
CAUTION Exercise caution when hand-
ling packaging materials.
Observe applicable safety and accident preven-
tion requirements.
Store packaging material out of the reach of chil-
dren (risk of suffocation).
