■If there is coal dust or flour in
the air around the appliance,
this may cause an explosion.
Make sure that the area
around the appliance is kept
clean when it is in operation.
:Warning
Risk of fire/material damage/
damage to the appliance!
If a program is terminated
before the drying cycle has
finished, this prevents the
laundry from cooling down
sufficiently and may cause the
laundry to ignite, or may result
in material damage or damage
to the appliance.
■During the last part of the
drying cycle, the laundry in
the drum is not heated
(cooling cycle). This is to
ensure that it remains at a
temperature at which it will
not be damaged.
■Do not switch off the
appliance before the drying
cycle has finished unless you
remove all items of laundry
from the drum immediately
and spread them out (to
dissipate the heat).
:Warning
Risk of poisoning!
If additional appliances (such
as gas heaters, gas-fired
tankless water heaters, coal-
burning stoves connected to a
chimney or open fireplaces) are
being operated in the same
room as this appliance or in
adjacent rooms, this may
create a vacuum that sucks
exhaust gases back in. There is
a risk of poisoning if these
gases are inhaled.
Make sure that the area is
adequately ventilated. Always
have the chimney sweep
responsible confirm that your
appliance is operating safely.
:Warning
Risk of poisoning!
Poisonous fumes may be given
off by cleaning agents that
contain solvents, e.g. cleaning
solvent.
Do not use cleaning agents that
contain solvents.
