
Please observe the instructions in "Installation and connection"
and "Technical data".

The plugs for the washer-dryer stack must always be kept access-
ible so that the washer-dryer stack can be easily disconnected from
the power supply.

For hard-wired machines, an all-pole means of deactivation must
be provided on site.

If the washer-dryer stack is to be hard-wired, there must be a
means of disconnecting all poles from the power supply. The mains
isolators must be close to the washer-dryer stack and be clearly iden-
tifiable, unhindered and easily accessible at all times.

The tumble dryer may only be operated when the ducting has been
installed and the room is sufficiently ventilated.

The vent ducting must never be installed in any of the following
flues or shafts:
- Chimneys or smokestacks that are in use.
- Shafts that are used to ventilate installation rooms with fireplaces.
- Flues that are used by third parties.
Smoke or exhaust gas that is fed back into the flue or shaft may be
toxic.

Regularly check all components in the vent ducting (e.g. wall pipe,
external grille, bends, elbows, etc.) to make sure air can move
through them and to ensure that they are working properly. Clean
components when necessary. Fluff deposits in the vent ducting sys-
tem will prevent the air from being extracted properly and, as a result,
will stop the tumble dryer from working properly.
If existing vent ducting is due to be used, it must be checked before
being connected to the tumble dryer.
Low pressure must not occur in the vent ducting.

There is a risk of suffocation and poisoning due to exhaust gases
being sucked back if gas-powered flow heaters, gas-powered room
heaters, coal-burning stoves with a flue connection, etc., are installed
in the same room, in the same flat or in neighbouring rooms and the
negative pressure is 4 Pa or more.
The following measures for suitable room ventilation (examples) can
help to prevent negative pressure in the installation area:
- Install vents that cannot be closed in the exterior walls.
- Use window switches so that the tumble dryer can only be
switched on when a window is open.
Please always seek approval from your building regulations inspector
to confirm that the appliance can be operated without risk and that
negative pressure of over 4 Pa can be prevented.
