UK | 7 Safety instructions and warnings
Risk of injury and risk to health from
parts which may affect the ventilation
system which are added or modified at a
later date.

Parts (range hood, air-ventilated fireplace
etc.) which are added or modified at a later
date may result in health risks and operation
which is not permitted. Parts may only be
added or modified at a later date if system
compatibility is established/ensured by a
planning office. If using an exhaust air range
hood or air-ventilated fireplace, this must be
accepted by a professional chimney sweep.
Risk when using accessory compo-
nents which have not been approved.
The ventilation unit is tested and approved
with original accessory components.

Retrofitting (bypass, PTC heat register,
heat exchanger
etc.) is only permitted with original compo -
nents.

Note space needed for additional compo-
nents (tubular sound absorber, supplementary
heating etc.).

Other modifications and alterations to the
unit are not permitted and release the manu-
facturer from any guarantee and liability.
Risk of injury from damaged ventila-
tion units.

Switch the ventilation units off immediately
if you discover damage or faults that could
endanger persons or property.

Prevent the unit from being switched back
on until it has been fully repaired.
Danger of electric shock.

Before removing the front cover and
installing the electrics, switch off all supply cir -
cuits and secure them against being acciden -
tally switched back on again. Attach a warning
sign in a clearly visible place.
Danger from electric shock, fire or
short-circuiting when failing to comply
with the relevant regulations for electrical
installations.

Do not perform any tasks on live parts.

Be sure to observe the relevant regulations
for electrical installation; e.g. DIN EN 50110-1.
In Germany, particularly observe VDE 0100,
with the corresponding sections.

Comply with the electrotechnical safety
regulations (disconnect from voltage, secure
against being accidentally switched back on,
ensure de-energisation and cover or block off
neighbouring live components.

A mains isolation device with contact
openings of at least 3 mm at each pole is
mandatory.

Only connect the unit to a permanent elec -
trical installation.

The unit may only be operated using the
voltage and frequency shown on the rating
plate.
Make electrical connections according to
wiring diagram.

Avoid touching components.

Maintenance and fault finding only permis -
sible when carried out by trained electricians.
Risk of injury from running fans when
removing the front cover.

Before removing the front cover, wait until
both fans have stopped.
Danger of burning from hot housing
parts on units with PTC heat register
when removing the front cover.

After removing the front cover, do not touch
the heat register. First wait until the heat reg -
ister and the housing parts have cooled off.
Risk of death from toxic air nearby
containing pollutants (smoke, va-
pours) in the event of a fire or chemicals
accident etc.

Switch the entire ventilation system off
immediately until the outside air is safe again.
