UK | 7 Safety instructions and warnings
Risk to health if ventilation unit is not
correctly cleaned.
 Clean the ventilation unit regularly, at
least every 2 years. This is the only way of
ensuring that the ventilation unit is running
hygienically.
WS 160 Flat: Risk of injury/damage to
unit when removing the filter cover,
the front cover or heat exchanger (instal-
lation/removal/cleaning/maintenance). The
filter cover is fixed. The front cover is very
heavy. Sometimes the heat exchanger is hard
to pull out/slide in.
 Ensure that you are standing securely and
cannot lose your balance and that there is no
one under the unit (risk of injury from falling
components). Have a second person provide
assistance.
 When removing and installing the com-
ponents, support them from below with one
hand.
 Deposits/dust can fall down when remo-
ving the front cover. When performing work
overhead, protect your eyes and airways.
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.
Risk of injury when handling sharp
components, e.g. front cover, heat
exchanger retaining strap.
Wear protective gloves.
Risk during transport from heavy or
falling loads.
 Observe applicable safety and accident
prevention requirements.
 Note permissible maximum loading capaci-
ty of lifting gear.
 Exercise caution when lifting. Note trans-
port weight (up to 73 kg) and centre of gravity
40
of ventilation unit (centre). Only carry the unit
together with several persons and attach it to
the ceiling.

 Do not stand under a suspended load.
 Check unit for transport damage. Do not
commission a damaged unit.
Intended operation not ensured if
installed incorrectly. A ventilation unit
not installed correctly may result in operation
not as intended.
 Only install ventilation unit in accordance
with the planning specifications.
 In particular, note the information on insula-
ting ventilation channels and sound deade-
ning. Recommendation: Use tubular sound
absorber for sound-deadened installation of
ventilation unit.
Risk from operating with ventilation
unit not fully installed (open unit/
without duct connections). Running fans
can be touched. Electric components are a
potential source of electric shock. There is a
danger of burning on units with a PTC heat
register on the protective grill and on the
components of the heat register.
 Only operate ventilation unit with all fitted
duct connections and when it is completely
installed (with front cover mounted).
 Absorbers significantly reduce the noise
emissions.
 Insulate ducts sufficiently to prevent diffu-
sion.
Wear protective gloves on units with a
PTC heat register
