5
The fan unit must not be used in the
following situations under any
circumstances.
Risk of combustion/danger of fire
from flammable materials, liquids or
gases in the vicinity of the fan. Do not
place any flammable materials, liquids or
gases near the fan, which may ignite in the
event of heat or sparks and catch fire.
Steam-saturated or greasy air or
solid particles which may stick to
the fan, can soil the fan and reduce the
efficiency.
Never use fan to convey these
substances.
Explosive gases and dusts may
ignite and cause serious explosions
or fire. Never use fan unit in an explosive
atmosphere (risk of explosion).
Explosive substances in lab
extraction units may ignite and
cause serious explosions or fire.
Aggressive substances may damage the fan.
Never use fan in combination with a lab
extraction unit (risk of explosion).
Risk to health from chemicals or
aggressive gases/vapours. Chemicals
or aggressive gases/vapours may harm
health, especially if they are distributed
throughout the rooms by the fan. Never use
fan to distribute chemicals or aggressive
gases/vapours.
During the build phase, damage to
unit caused by soiling of the fan and
air channels.
Fan operation is not permitted
during the build phase.
Grease and oil vapours from range hoods
may contaminate the fan and air channels
and reduce efficiency. Never use fan to
convey greasy air.
Damage to the unit when
continuously conveying steam-
saturated air.
Never use fan to convey
steam-saturated air.
Damage to the unit due to imbalance
of the impeller when conveying solid
particles . Never use fan to convey solid
particles that could stick to the fan.
Damage to unit in the event of
moisture ingress. Fan with IP X5
degree of protection (jet-water protection).
Never use fan outdoors.
Observe all safety instructions.
Risks for children and
people with reduced
physical, sensory or mental
capabilities or a lack of
knowledge. Fan may only be
installed, commissioned,
cleaned and maintained by
people who can safely
recognise and avoid the risks
associated with this work.
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.
