Disposal of the packing
material
The transport and protective packing
has been selected from materials which
are environmentally friendly for disposal
and should be recycled.
Ensure that any plastic wrappings,
bags, etc are disposed of safely and
kept out of the reach of babies and
young children. Danger of suffocation.
Disposal of your old appliance
Electrical and electronic appliances
often contain materials which, if
handled or disposed of incorrectly
could be potentially hazardous to
human health and to the environment.
They are, however, essential for the
correct functioning of your appliance.
Please do not therefore dispose it with
your household waste.
Please dispose of it at your local
community waste recycling centre or
contact your dealer for advice. Ensure
that it presents no danger to children
while being stored for disposal.
Energy saving tips
To avoid unnecessarily long drying
times and high consumption of energy:
–Make sure that your laundry is
thoroughly spun before drying.
The higher the spin, the greater the
savings that can be made in energy
and time during drying.
–Load according to the optimum
amount of laundry recommended for
the programme being used (see
Programme chart).
Underloading is uneconomical.
Overloading gives a poorer quality of
drying and may cause unnecessary
creasing.
– Make sure the room in which the
dryer is located is well ventilated.
– Make sure the fluff filters are clean
before using the dryer.
– Check the condenser unit from time
to time and clean it when necessary.

~The socket must be easily accessible after installation in order to
disconnect the tumble dryer from the electricity supply.
~Do not block the gap between the base of the tumble dryer and
the floor with plinth facings, deep pile carpet etc. as this would
hinder a sufficient intake of air.
~Make sure the tumble dryer door can be opened without
hindrance after installation.
Correct use
~The maximum load of dry laundry for this tumble dryer is 7 kg.
See the Programme chart for the maximum recommended loads in
individual programmes.
~Fire hazard.
The tumble dryer must not be connected to a controllable socket
(e.g. a timer switch or a peak load shut-off device).
If the drying programme were to be interrupted before the end of the
cooling down phase, the laundry could self-ignite.
Warning and Safety instructions
10

~To prevent the risk of fire, the following textiles must not be dried
in this appliance:
–items which have not been washed.
–items, such as workwear, which have not been thoroughly
cleaned and which are still soiled with grease, oil or other
deposits (such as cosmetics, lotions etc).
If items have not been thoroughly cleaned there is a danger that
these might self-ignite when heated, even after they have been
removed from the tumble dryer at the end of the programme.
–items (e.g. mops and floor cloths) which have been treated with
inflammable cleaning agents or which contain residues of
acetone, alcohol, benzine, petrol, kerosene, stain remover,
turpentine, wax, wax remover or other chemicals.
– items which have been splashed with hair lacquer, hair spray, nail
varnish remover or similar substances.
When washing such heavily soiled items, ensure that you use
additional detergent and select a high temperature. If in doubt,
wash the items several times.
~Remove all items such as lighters and matches from pockets.
~Warning: Do not switch the tumble dryer off before the drying
programme has finished. If this is done, the laundry must be hung
up or spread out to cool it down.
~Fabric conditioner and similar products must be used according
to the instructions on the manufacturer's packaging.
Warning and Safety instructions
11

~To prevent the risk of fire, the following must not be tumble dried:
–items which have been cleaned using chemicals (e.g.
professional dry-cleaning agents).
–fabrics which contain a large proportion of rubber, foam rubber or
rubber-like materials. For example, products made from latex
foam rubber, shower caps, waterproof textiles, rubberised articles
and items of clothing and pillows with foam rubber filling.
–damaged items which contain padding or fillings (e.g. pillows,
jackets). When damaged, the filling can get out with the risk of
igniting in the tumble dryer.
~In many programmes, the heating phase is followed by a cooling
down phase to ensure that the items remain at a temperature which
will not damage them and so that they are not too hot to handle
when you remove them (this also avoids the danger of the laundry
self-igniting). The programme is not finished until the cooling down
phase has been completed.
As soon as the programme has finished, remove all laundry from the
drum.
~Do not let anyone sit or lean on the door, as this can cause the
tumble dryer to tip up.
~Always close the doors after use. This way you will avoid the
danger of:
–children climbing into the tumble dryer or hiding things in it.
–pets or other small animals climbing into it.
Warning and Safety instructions
12

~The tumble dryer must not be used without the fluff filters in place
or if the fluff filters are damaged in any way.
~The fluff filters must be cleaned regularly.
~The tumble dryer must not be used without the condenser unit in
place.
~The fluff filters must be thoroughly dried after cleaning. Damp or
wet filters could cause operational faults.
~Do not install the tumble dryer in a room where there is a risk of
frost occurring. At temperatures around freezing point the tumble
dryer may not be able to operate properly. There is a risk of damage
if the condensed water is allowed to freeze in the pump and in the
drain hose.
The ambient room temperature should be between +2°C and
+35°C.
~If the water is drained externally instead of being collected in the
condensed water container, make sure the drain hose is securely
attached if you hang it in a sink or basin to avoid the hose slipping
and the water causing damage.
~Condensed water is not drinking water.
It can cause health problems in both people and animals.
~Always keep the area around the tumble dryer free of dust and
fluff. Dust and dirt drawn into the tumble dryer can cause blockages
in the condenser unit over time.
~The tumble dryer must not be hosed down.
Warning and Safety instructions
13

for more details.
Perfect Dry indicator
The Perfect Dry system measures the
residual content in the laundry in the
sensor drying programmes to ensure
perfect drying results.
After a programme has started, the
electronics will estimate the duration of
the programme (time remaining). The
Perfect Dry indicator will flash while this
is happening.
After a short while, the programme
duration will appear in the display and
the indicator will go out.
The Perfect Dry indicator will light up
again when the selected drying level is
reached and remain on until the
programme is finished.
The Perfect Dry indicator does not light
up during time controlled programmes:
Woollens handcare, Cool air, Warm air,
Gentle smoothing.
Programme duration /
Estimated time remaining
The estimated duration (time remaining)
will appear in the display.
The following factors all affect the
estimated time remaining: residual
moisture content after spinning; type of
fabric; size of load; room temperature;
fluctuations in power supply.
The electronics continually assess
conditions in the dryer and adjust the
estimated time remaining for a more
accurate reading. Because of this, the
time displayed can alter during the
course of a programme.
Programmes can also finish earlier than
expected, if, for example, particularly
fine fabrics are being dried, the load is
very small or items were partially dry
beforehand.

Tips on drying
– Always observe the maximum
recommended loads given in the
"Programme chart". Never overload
the drum.
Overloading can cause
unnecessary wear and tear to the
laundry, give a disappointing drying
result and cause more creasing.
–Do not put soaking wet items into the
tumble dryer. Spin fabrics for at least
30 seconds before drying.
–Open jackets so that they can dry
evenly.
–Use the Automatic plus programme
for drying mixed loads of cotton and
minimum iron fabrics.
–Woollens and wool blends tend to
become matted and shrink if dried in
a tumble dryer. They can, however,
be "fluffed up" using the Woollens
handcare programme.
–Down-filled garments have linings
which have a tendency to shrink,
depending on the quality of the item.
They can be partially dried using the
Gentle smoothing programme.
–Pure linen should only be machine
dried if specified as suitable by the
manufacturer on the care label, as
the surface of the fabric may
otherwise become rough.
–Loopknit garments (e.g. T-shirts and
underwear) tend to shrink depending
on their quality. Do not over-dry
these textiles. When purchasing
these garments it is advisable to take
their shrinkage properties into
account.
– Minimum iron fabrics tend to crease
more, the larger the load. This is also
the case for garments made from
very fine weave fabrics, such as
shirts or blouses.
If in doubt, divide the garments into
smaller loads.
–Starched laundry can be dried in the
tumble dryer. To achieve the usual
finish, double the amount of starch
should be used.
–New dark coloured garments should
be washed and dried separately
from light coloured garments to avoid
the danger of colours running and
discolouring other garments or even
plastic components in the dryer.
Dark coloured fibres can also settle
on light coloured garments and vice
versa.
