Risk of explosion:
Explosive substanc-
es in lab extraction units may ignite and
cause serious explosions or fire. Aggressive
substances may damage the
ventilation unit.
Never use ventilation unit in combination
with a lab extraction unit.
Risk to health from chemicals or ag-
gressive gases/vapours.
Chemicals or aggressive gases/vapours may
harm health, especially if they are distributed
throughout the rooms by the ventilation unit.
Never use ventilation unit to
convey chemicals or aggressive gases/va
-
pours.
During the build phase, damage to
unit caused by contamination of the
ventilation units and piping.
Ventilation
unit operation is not permitted during the build
phase.
Grease and oil vapours from range
hoods may contaminate the ventila-
tion unit and reduce efficiency.
The ventilation unit should not be used with
range hoods in exhaust air mode. Recom
-
mendation: In terms of energy consumption,
use range hoods in circulating air mode.
Damage to unit caused by condensate
if ventilation units with enthalpy ex-
changers are used in rooms with exhaust
air humidity with an air humidity of > 70 %
r.h.
Never use ventilation units with enthalpy
exchangers for long periods at an air humidity
> 70 % (can be used briefly up to a r.h. of
around 80%) (for example in swimming pool
complexes or to dry out new buildings). The
ventilation unit does not have a conden-
sate drain and will be damaged by excess
condensate that cannot be removed. The
surroundings may also be damaged by water
escaping.
Corrosion of metal parts inside the
ventilation unit due to additional com-
ponents in the exhaust duct.
Do not use components which affect
temperature, moisture or air volumes on the
exhaust duct, for example if a drying cabinet
is connected to the exhaust duct.
Read and observe the safety in-
structions.
Ask your specialist installer
to instruct you in how to use the venti-
lation units/operating units.
Risks for people (including children)
with reduced physical, sensory or
mental capabilities or a lack of knowl-
edge.
Only have ventilation unit installed,
commissioned, cleaned and maintained by
persons who can safely recognise and avoid
the risks associated with this work.
Risk to health if filters are not re
-
placed or if there are no air filters.
Heavily contaminated filters may
collect sub-
stances hazardous to health
(mould, germs
etc.). This may also happen if the ventilation
unit is not used for an extended period. If
there are no
air filters, the ventilation unit and
ducts become dirty. Unfiltered substances
may enter the rooms.
Never operate ventilation unit without air
filters.
Only use original air filters.
Take prescribed filter class into account.
Note the filter change display and change
the air filters regularly.
Replace them after 6
months at the latest.
If the ventilation unit has not been used for
a long time, always replace the air filters.
Risk to health if ventilation unit is not
correctly cleaned.
Clean/service the
ventilation unit
regular
-
ly, at least every
2 years
. This is the only way
of ensuring that the ventilation unit is running
hygienically.
