Operation of the ventilation
unit is only permitted if all
required connections in
conjunction with the provided installed
components, such as sound absorbers
etc., have been properly established.
Upon the occurrence of any
defects or damage that are
able to injure people or dama-
ge property, the system has to be put out
of operation immediately. Further opera-
tion must be effectively prevented until
the device is completely repaired! Where
fault messages or damage occur, the
device must be immediately switched off
and disconnected from the mains.
When opening the front covers or
removing cover plates, act in a safety-
conscious manner and be aware of
the risks. Every working method that
impairs safety is prohibited.
Operation of the device is only permitted
with a connected air line or installed
system components, such as sound
absorbers, with a minimum line
length of 1000 mm to ensure that the
fans or electrical components, for ex-
ample, cannot be touched by hand.
The ventilation unit must be operated
only in compliance with the project do-
cuments. These must comply with
the equipment and product safety act
and with the relevant applicable stipula-
tions of the EC directives and
standards.
Never operate the ventilation unit wit-
hout installed air filters. The air filters
must be checked regularly for conta-
mination and damage and cleaned or
replaced if necessary.
The air filters are to be replaced at least
every six months or when the alarm bell
appears on the control unit. Use only
genuine spare filters. If the system is not
in operation in the summer, for hygienic
reasons the air filters have to be repla-
ced before putting it back into operation.
In case of simultaneous use of the ven-
tilation unit with fireplaces consuming
indoor air, the applicable safety
instructions and standards must be
observed. In the case of indoor air de-
pendent fireplaces the combustion
air supply has to be provided separately.
Dunstabzugshauben dürfen in keinem
Fall, auf Grund der starken Belastung
sowie dem unregelmäßigen Betrieb in
den Abluft- oder Fortluftkreislauf des
Lüftungsgerätes integriert werden.
Owing to their heavy loading and irre-
gular operation, extractor hoods must
not be integrated into the extract air or
exhaust air circuit of the ventilation unit.
Advice on this is provided under
point
2.1.3 „Provisions for use with extractor
hoods „
. Exhaust air extractor hoods
must be operated via separate air lines,
with provision for a suitable fresh air
supply, e.g. by opening windows, or via
suitable air filters in recirculated air
mode.
3.2.4 Operation of the system
The electrical systems of the unit,
including their warning and protective
functions, shall be regularly checked
for perfect operation. The unit must be
shut down immediately in the event of
malfunctions or defects such as loose
connections or overheated cables.
Only original fuses with the prescribed ra-
ted current and dimensions may be used.
Damaged or faulty power supply cables
to the unit must be repaired immediately,
to avert potential danger. The unit may
not be operated unless safe operational
conditions have been restored.
Fault finding and immediate remediation
of electrical defects and malfunctions
shall be carried out by authorised electri-
cians only. All protective systems must be
checked (e.g. earth resistance etc.) after
completion of electrical work on the unit.
