The ventilation unit must be switched
off and disconnected from the mains
supply immediately in the event of a fault
message or damage. Be aware of your
safety and of hazards when opening the
front covers or removing cover plates.
Work practices that affect the safety of
the unit are prohibited. The unit may only
be operated with connected air ducts and
installed system components such as
acoustic dampeners and with a minimum
duct length of 1000 mm so as to ensure
that fans or electrical components cannot
be touched.
The ventilation unit may be operated only
in accordance with the project documen-
tation. The project documentation shall
comply with the Equipment and Product
Safety Act and the pertinent provisions of
the EC Directives and Standards.
Consider environmental impacts and
refrain from installing the ventilation units
in the vicinity of flammable liquids or gas-
es, in swimming pools or in areas exposed
to chemicals.
Never operate the ventilation unit without
an air filter. Air filters must be checked
regularly for dirt and damage and cleaned
or replaced if necessary. The air filters
must be changed at least every six
months or when the "Change Filter" mes-
sage appears on the control unit. Use
original replacement filters only. If the
plant is not used in summer, the air filters
must, for hygienic reasons, be replaced
prior to restarting.
Comply with safety requirements and
standards when operating the ventilation
unit simultaneously with ambient air-de-
pendent fireplaces or extractor hoods.
When using fireplaces dependent on am-
bient air, a combustion air supply must be
provided separately. See the provisions on
this topic under
the section "Provisions for
operation with fireplaces", page 6.
Due to their heavy burden and irregular
operation, extractor hoods must under
no circumstances be integrated into the
exhaust or extract air circuits of the venti-
lation unit. See the provisions on this topic
under
the section "Provisions for connec-
tion with extractor hoods, page 6".
Exhaust
air extractor hoods must be operated
via separate air pipes with suitable air
replenishment e.g. by means of window
ventilation or in air recirculation mode.
