Caution!
Risk of fire/risk of poisoning/risk of
material damage and damage to the
appliance
The appliance contains refrigerant
which, although it is environmentally
friendly, is flammable R290. Failure to
dispose of it properly may result in a fire
or poisoning.
Dispose of the appliance properly and
do not damage the pipes in the
refrigerant circuit.
Energy-saving tips
■Spin the laundry before drying.
The drier the laundry, the shorter
the drying time will be, thus
consuming less energy.
■Load the dryer with the maximum
load.
Note: Do not exceed the maximum
load for the programs, as this
prolongs the drying time
and increases energy consumption.
■Ventilate the room and keep the air
inlet on the dryer free to ensure air
exchange.
■Clean the fluff filter after each drying
cycle. If the fluff filter is dirty,
the drying time is prolonged
and energy consumption is
increased.
■Energy saving mode: If the dryer is
not operated for a prolonged period,
it automatically switches off before
the program starts and when
the program has ended to save
energy. The display panel
and indicator lamps go off after
a few minutes and the Start button
flashes. To activate the lighting,
press any button, open or close
the dryer door or turn the program
selector.
)Dispose of packaging in an
environmentally-responsible
manner.
This appliance is labelled in
accordance with European
Directive 2012/19/EU
concerning used electrical and
electronic appliances (waste
electrical and electronic
equipment - WEEE).
The guideline determines the
framework for the return and
recycling of used appliances
as applicable throughout the
EU.

Draining the condensation water en
13
ŒDraining the
condensation water
Drainingthecondensati onwater Condensation will form in the appliance
as it dries the laundry.
You must ensure that the drain hose is
connected when you operate the
appliance.
If there is no drain hose connected to
the appliance, the condensation water
from the appliance will run into the
condensation container. In this case,
you will need to empty the condensation
container each time the dryer finishes
drying the laundry, and also if it
becomes full before drying is complete.
Connect the drain hose as follows:
1. Remove the accessories from the
dryer drum.
2. When the dryer is delivered from the
factory, the hose for discharging the
condensation into the condensation
container is fastened to the
connecting piece.
3. Disconnect the hose from the
connecting piece and put it in the
"parked" position.
4. Take the drain hose from the
accessories and secure it to the free
connecting piece.

en Draining the condensation water

5. Fasten the other end of the drain hose with the remaining accessories,
depending on the connection situation (A, B or C).
Caution!
Accumulated water can be drawn back into the dryer and may cause material
damage.
Check that the water drains away from the wash basin quickly. The drain must
not be sealed or blocked.
Caution!
Material damage due to leaks or draining water.
Secure the drain hose so that it cannot slip out.Do not kink the drain hose.
Ensure that a height difference of max. 100 cm and min. 80 cm between the
installation surface and the drain is maintained for drainage into a siphon.

Laundry Preparing the laundry
:Warning
Risk of explosion/fire!
Remove any cigarette lighters and
matches from pockets.
Caution!
The dryer drum and fabrics could be
damaged.
Remove all objects from pockets and
observe the following information:
■Tie cloth belts, apron strings, etc.
together or use a laundry bag.
■Close zips, hooks and eyelets and
buttons. Button up large items of
laundry, such as covers.
■Remove any metal objects, such as
paper clips, from pockets.
■To ensure a consistent drying result,
sort laundry by fabric type and
drying programme.
■Always dry very small items of
laundry, e.g. babies' socks, together
with large items such as towels.
■Knitted fabrics such as T-shirts and
jerseys often shrink the first time they
are tumble-dried. Use a gentle
programme.
■Do not overdry easy-care laundry.
This increases creasing of the
laundry.
■Use timed programmes for single
garments.
■Some detergents and care products,
e.g. starch or softeners, contain
particles which may be deposited on
the moisture sensor. This may impair
the sensor function and in
consequence the drying result.
Notes
– When washing laundry to be
tumble-dried, use the correct
amount of detergent and care
products as specified in the
manufacturer's instructions.
– Clean the moisture sensor
regularly ~Page 30.
Sorting washing according to:
cSuitable for tumble drying
aDry at normal temperature
`Dry at low temperature
bDo not tumble-dry
Note: Do not load laundry from the
washing machine directly into the
tumble dryer. Sort the spun laundry
before placing it in the dryer drum.
If you dry thin, thick and multi-layer
fabrics together, they will dry to differing
degrees. To achieve an even drying
result, you should therefore only dry
together laundry of the same type of
fabric and structure. If you feel that the
laundry is still too damp, you can select
a timed programme for subsequent
drying ~Page 21.
Caution!
Possibility of material damage to the
dryer or laundry.
Do not tumble-dry the following
fabrics:
■Laundry contaminated with oil.
■Unwashed fabrics.
■Non-breathable fabrics (e.g. rubber-
coated).
■Easily damaged fabrics such as silk,
synthetic curtains.
