NOTICE: Damage to the unit
● During the build phase, damage to unit
caused by contamination of the device
and piping.
 Ventilation unit operation is not permit-
ted during the build phase.
● Grease and oil vapours from range
hoods may contaminate the unit and
ventilation ducts and reduce efficiency.
 Never use ventilation unit in combina-
tion with range hoods, that are connected
directly to the controlled domestic venti-
lation exhaust air channel. In rooms with
greasy exhaust air, e.g. kitchens, only use
ventilation valves with a grease filter.
Recommendation: In terms of energy con-
sumption, use range hoods in circulating
air mode.
● Damage to unit caused by condensate if
ventilation units with enthalpy exchang-
ers are used in rooms with exhaust air
humidity with an air humidity of > 70 %
RH.
 Never use ventilation units with enthalpy
exchangers for long periods at an air
humidity > 70 % (can be used briefly up
to an RH of around 80%) (for example in
swimming pool complexes or to dry out
new builds). The ventilation unit does not
have a condensate drain and will be dam-
aged by excess condensate that cannot be
removed. The surroundings may also be
damaged by water escaping.
● Corrosion of metal parts inside the ven-
tilation unit by additional components
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
instructions.
After commissioning, allow your
specialist installer to explain
how to use the ventilation unit
and control units.
DANGER
!
Risk to health if filters are not
replaced or there are no air
filters.
Heavily contaminated or damp
air filters may collect substanc-
es hazardous to health. This
may also happen if the ventila-
tion unit is not used for a long
time. If there are no air filters,
the ventilation unit and ducts
become dirty. Unfiltered sub-
stances may enter the rooms.
 Never operate ventilation
unit without air filters.
 Only use original air filters.
 Note the filter change
display and change the air
filters regularly. Replace them
after the specified intervals
(chap. 16) at the latest.
 If ventilation unit has not be
used for a long time,
always replace the air filters.
