may result in non-intended operation or im-
permissible operation.
Operation is only permitted with a correct installa-
tion position (see TOP on unit), with mounted
design cover and outer protective grille.
The fan may be operated only if the protection
against accidental contact with the impeller is
guaranteed to be in accordance with DIN EN ISO
13857.
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

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.
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.
DANGER Danger of electric shock when
operating a fan which is damaged or 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 and
position a visible warning sign.
Only operate the fan when it is completely in-
stalled.
Do not commission a damaged unit.
DANGER Danger if the relevant regula-
tions for electrical installations are not ob-
served.
Before installing the electrics, shut down all sup-
ply circuits, deactivate the mains fuse and secure
it so it cannot be switched back on. Attach a
warning sign in a clearly visible place.
Be sure to observe the relevant regulations for
electrical installation; e.g. DIN EN 50110-1. In
Germany, particularly observe VDE 0100, with
the corresponding sections.
A mains isolation device with contact openings of
at least 3 mm at each pole is mandatory.
Only connect unit to permanently wired electrical
installation and with NYM-O or NYM-J cables,
depending on the unit type, 3 x 1.5 mm² or 5 x
1.5 mm².
The unit may only be operated using the voltage
and frequency shown on the rating plate.
Unit may be energized even when at a standstill
and may be started up automatically by sensors,
such as those for time delay or humidity etc.
The degree of protection stated on the rating
plate is only guaranteed if installation is under-
taken correctly and if the connecting cable is cor-
rectly guided through the cable grommet. The
grommet must tightly seal the cable sheathing.
With protection class I, connect the PE conductor
and check the connection.
CAUTION Exercise caution when hand-
ling packaging materials.
Observe applicable safety and accident preven-
tion regulations.
Store packaging material out of the reach of chil-
dren (risk of suffocation due to swallowing).
Supply air intake within the living area
• The domestic air supply must be set up so that
virtually no air from the kitchen, bathroom and
WC can flow into the living areas in which the
unit is installed.
• A room from which the air is to be extracted
must be fitted with a non-closable, free supply
air cross section of at least 150 cm², e.g. with
MLK door ventilation grille.
