Warning and Safety instructions
~
The tumble dryer must only be used when it is connected to a
suitable ducting system. The installation site must be adequately
ventilated.
~
The ducting must not be connected to
– a chimney or vent flue which is in use,
– or to ducting which ventilates rooms with fireplaces,
– or to chimneys being used by other appliances.
Smoke or exhaust fumes can cause poisoning.
~
Check all parts of the extraction system on a regular basis (e.g.
wall vent, external grille, bends in the ducting etc.) and make sure
they are all free of any hindrance. A build-up of fluff will prevent a
free flow of air through the system. If the dryer is to be connected to
an existing ducting system, this must be checked for suitability
beforehand.
~
Adequate ventilation is essential to avoid the danger of
asphyxia and toxic fumes where another appliance which also
uses the room air (e.g. gas, oil or coal fired heater, continuous flow
or other water heater) is installed in the same or an adjacent room.
To ensure safe operation, and to prevent gases given off by these
appliances being drawn back into the room, an underpressure of
4 Pa is the maximum permissible.
Ventilation can be maintained by:
– air inlets in the external wall which cannot be closed or blocked,
or
– by fitting a window contact switch which ensures that the
appliance can only be operated when the window is open.
To ensure safe operation of your tumble dryer and to avoid an
underpressure of 4 Pa or more, please seek professional advice.
