4. Safety instructions and warnings
6
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 can also occur during a
prolonged shutdown of the fan. If the air
filter is missing, the fan and air channels
become soiled.
Never operate the fan
without air filters. Only use original filters.
Regularly change air filter when a filter
change is indicated (LED or TimeStrip). If the
fan has not been used for a long time, always
replace the air filters.
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 cannot lose your balance and
that there is no one under the unit.
Exercise caution when handling
packaging materials.
Observe
applicable safety and accident prevention
requirements. Store packaging material out of
the reach of children (risk of suffocation).
Risks from parts which may affect
the ventilation 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 established/ensured by a planning office. If
using an exhaust air range hood or air-
ventilated fireplace, this must be accepted by
a regional master chimney sweep.
Danger from operating with the fan
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
positioned. Only operate the fan when it is
completely installed.
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 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.
Danger if the relevant regulations for
electrical installations are not
observed.
●
Before removing the housing cover or
removing the fan insert and before
installing the electrics, switch off all supply
circuits, switch off mains fuse, and secure
them against being accidentally switched
back on again. Attach a warning sign in a
clearly visible place.
●
Be sure to observe the relevant regula-
tions for electrical installation; e.g. DIN EN
50110-1. In Germany, particularly observe
VDE 0100, with the corresponding
sections.
●
Unit may also be energized even when at
a standstill and may be switched on
automatically by sensors (time delay,
humidity etc.) or by the thermal switch in
the motor winding. Maintenance and fault
finding only permissible when carried out
by trained electricians.
●
The degree of protection stated on the
rating plate is only guaranteed if
installation is undertaken correctly and if
the connecting cable is correctly guided
through the stepped grommet (The
grommet must completely enclose the
cable sheathing). The fan insert must also
be engaged and the housing cover
installed.
