Health risk due to deposits on the
unit (mould, bacteria, dust etc.) after
the fan has not been used for a long
time. Clean unit at regular intervals, espe-
cially after the fan has not been used for a
long time.
A fan that is not mounted correctly
may result in non-intended operation
or impermissible operation. Ensure
that foreign bodies cannot be sucked into
the unit and ducts. For fans with a free inlet,
fit a protective grille (e.g. Protective grille
SG). The fan can only be operated if protec-
tion against accidental contact with the
impeller is guaranteed in accordance with
EN ISO 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 duct sleeve
is drilled at a point which is not permitted.
Risk of injury/damage to unit if the
fan falls during installation/removal
(mounting/dismantling/cleaning/main
tenance) (weight 6 to 17 kg, depending on
type). During mounting work, ensure that you
are standing securely and cannot lose your
balance and that there is no one under the
unit. When removing and installing the unit,
support it from below with a hand.
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.
3. Safety instructions and warnings │ UK
High noise emissions near the fan.
Use additional visual warning signals
to secure the workplace area.
Risk of injury when handling
housing parts with sharp edges.
Wear protective gloves.
Risk during transport from heavy or
falling loads. Observe applicable
safety and accident prevention
requirements. Do not stand under a
suspended load. Check unit for transport
damage
Danger of electric shock when opera-
ting a fan which is damaged or not
fully mounted. Before working on the
fan, 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 installed. Do not
commission a damaged unit. Prevent the unit
from being switched back on until it has been
fully repaired
Hearing damage caused by spending
prolonged periods directly next to
the unit while it is running. Depending on
type, sound power levels of up to 76 dB(A).
When planning, take into account sound
insulation at the installation site when
planning. If necessary, use hearing
protection.
Risk of injury in case of incorrect
mounting, if the fan falls down due
to its inherent weight. The fan vibrates
slightly. Wall mounting only on walls with
sufficient load-bearing capacity and with
sufficiently dimensioned mounting material.
Risk of burns due to hot motor. The
motor can still be hot after switching
off the device. Cool-down time can be
up to 30 minutes.
