Safety instructions

For your own safety, please read the following
safety instructions carefully before starting
to work with the unit. Please keep these
instructions in a secure place to ensure future
safety of operation.
•
Electrical connection work and repairs should
only be carried out by qualified electricians.
•
During electrical installation, ensure compliance
with the corresponding regulations, in particular
the pertinent sections of DIN VDE 0100. In
rooms with a bath or shower installed, for
example, part 701 is relevant.
•
Danger from rotating impeller: While the unit
is running, do not get too close to it with loose
hair or clothing as they may get caught up in it.
•
Do not insert any objects through the external
grille or the internal housing while the fan is
running as this may cause damage or injury.
•
This device may only be used:
– when correctly installed in flat glass windows
or in wall or wooden panels (see Installation
chapter).
– when there is sufficient space between it and
the window frame, wall or ceiling.

shutter and internal housing.
– only if the external shutter is operated together
with the EVN-22 internal part.
•
This device may not be used:
– with hinged double-glazed windows.
– in vicinity to inflammable materials, fluids or
gases.

•
If the fans are being used with air-ventilated
fireplaces, you must ensure that there is sufficient
flow of supply air. The maximum permitted
pressure difference is 4 Pa.
•
The maximum permitted airstream temperature
is 40°C.
•
The motor has a thermal overload protection,
which switches the unit off in the event of
overheating. Once the unit has cooled down
again, the fan switches back on automatically.
•
Before removing the terminal box cover [4],
disconnect the unit completely from the power
supply. To do this, switch off the mains fuse at
the fuse box.
