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.

2 Safety instructions
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.
Take prescribed filter class
into account.
Note the filter change
display and change the air
filters regularly. Replace them
after 6 month at the latest.
If ventilation unit has not be
used for a long time,
always replace the air filters.
