6

IMPORTANT SAFETY INSTRUCTIONS
 Important information regarding use of fabric softener sheets:
We do not recommend use of fabric softener sheets. Use of fabric
softener sheets can clog the surfaces of the lint filters, extending the
drying time and increasing energy consumption. During subsequent
cleaning, the plastic and surfaces of the lint filters can be damaged!
The best results are obtained by using liquid fabric softener in the
washing machine. Follow the manufacturer's instructions.
If you still wish to use fabric softener sheets, be sure to follow the
cleaning instructions under “Cleaning and care” in the “Cleaning
instructions when using fabric softener sheets” section.
Tip:
Using a fragrance flacon (optional accessory) will add a pleasant
fragrance to your laundry.
When a fragrance flacon is used, the fragrance is acquired by the
entire load of laundry. The disadvantage of fabric softener sheets is
that under certain circumstances the fragrance is acquired by only a
few items of laundry, especially when drying a full load.
When you use a fragrance flacon, always follow the warnings
in this section as well as those under “Fragrance flacon”.
7

IMPORTANT SAFETY INSTRUCTIONS
 To prevent the risk of fire, the following textiles must not be dried
in this dryer:
– items which have not been washed.
– items, such as work-wear, exposed to grease, oils, or other
deposits (such as lotions or cosmetics) in your dryer. If these
items have not been thoroughly cleaned there is a danger that
they may contribute to a chemical reaction that could cause the
laundry to ignite when heated even after being removed from the
dryer.
– items that have been previously cleaned, washed, soaked or
spotted with gasoline, dry-cleaning solvents or other flammable
or explosive substances. They may give off vapors that could
ignite or explode.
– items treated with flammable cleaning agents or items containing
acetone, alcohol, petrol, stain remover, wax or chemicals from
buffing, etc.
– items which have been splashed with hair spray, nail polish
remover, etc.
When washing heavily soiled items ensure that sufficient
detergent is used with a high temperature. If in doubt wash the
item several times.
– items containing foam rubber or similarly textured rubber-like
materials.
– items with padding or filling (e.g. pillows or jackets) which have
been damaged. Loose filling could catch fire.
8

IMPORTANT SAFETY INSTRUCTIONS
 Allow the dryer to complete each stage of the program selected,
including the cooling down phase. This will ensure that the items
being removed are not too hot to handle.
 Clean the lint filter before or after each load.
 Keep the area around the air intake (toe kick) and adjacent
surrounding areas free from lint, dust and dirt.
 The interior of the machine should be cleaned periodically by
qualified personnel.
 GROUNDING INSTRUCTIONS
This appliance must be grounded. In the event of malfunction or
breakdown, grounding will reduce the risk of electric shock by
providing a path of least resistance for electric current. This
appliance is equipped with a cord having an equipment grounding
conductor and a grounding plug. The plug must be plugged into an
appropriate outlet that is properly installed and grounded in
accordance with all local codes and ordinances.
 WARNING – Improper connection of the equipment-grounding

The heat pump in this tumble dryer uses a gaseous refrigerant which
is condensed by the compressor. The refrigerant, which is brought to
a higher temperature level and liquified by condensing, is led in a
closed circuit through the heat exchanger unit where heat exchange
with the circulating drying air takes place.
– The humming noises caused by the heat pump during the drying
process are normal. This does not impair the efficient functioning
of the dryer.
– The refrigerant is not flammable or explosive.
– This tumble dryer contains fluorinated greenhouse gases.
Hermetically sealed.

Energy saving tips
17
This dryer with heat-pump technology
is designed for energy-saving drying
cycles. However, you can save a little
more energy with the following
measures as the drying time is not
extended unnecessarily.
– Make sure your laundry is spun at the
maximum spin speed before drying.
The higher the spin speed, the
greater the savings that can be made
in energy and time during drying, e.g.,
approx. 20% energy can be saved if
spun at 1,600rpm instead of
1,000rpm.
– Load according to the optimum
amount of laundry recommended for
the program being used. This will
mean that the energy consumption
for the amount of laundry is at its
most economical.
– Make sure that the room temperature
is not too high. If there are other heat-
producing appliances in the room in
which the dryer is located, make sure
the room is well ventilated and switch
the other appliances off, if possible.
– Clean the lint filters in the door
opening after every drying cycle.

Functioning of the heat-pump dryer
18
Two separate circuits ensure that the
laundry is dried:
Dry air circuit
The drying air flows through a heat
exchanger, the drum, and several
filters. This is ensured by a blower in
the dryer.
– The drying air flows through the heat
exchanger in the longitudinal
direction and is heated in the rear
area.
– The drying air is then blown into the
drum, where it absorbs the moisture
of the laundry.
– The damp drying air is blown back
through the heat exchanger via
several filters in the fill area and the
plinth area of the dryer.
– The drying air cools down in the
front, cool area of the heat
exchanger, and loses its moisture.
– The circuit begins again.
Refrigerant circuit
The refrigerant circuit regulates the
heating and cooling of the drying air
through the heat exchanger. The heat
pump is the central component: This
is a compressor that is connected to a
pipeline system which is filled with
refrigerant.
– The pipeline system surrounds the
heat exchanger in several bends.
– The compressor draws in the
gaseous refrigerant and compresses
it, causing the temperature to rise.
– The hot refrigerant is passed through
the pipeline system to the rear of the
heat exchanger. The heat is released
into the drying air, which flows
through the heat exchanger.
– The refrigerant liquifies by dissipating
the heat.
– The liquid refrigerant then flows
through a capillary tube (a very thin
tube) to the front area of the heat
exchanger. This changes the
pressure of the refrigerant.
– The refrigerant cools and reverts to
its gaseous state. This in turn cools
the front area of the heat exchanger
and dehumidifies the drying air.
– The circuit begins anew.

Initial set-up
19
Removing the protective film
and stickers
Remove:
– The protective film from the door
– Any stickers (if present) from the front
and the lid
Please do not remove any labels
(e.g., the data plate) which are visible
when you open the door.
Carrying out the procedure for
initial commissioning outlined
in these instructions
Read “1. Notes on correct laundry
care” and “2. Loading the tumble
dryer”.
You can then load the tumble dryer
and select a program as described in
“3. Selecting a program and starting
it”.

1. Notes on correct laundry care
20
Points to note regarding
washed laundry
– When washing very heavily soiled
items, ensure that you use sufficient
detergent and select a high
temperature. If in doubt, wash the
items several times.
– Do not load the drum with items that
are still soaking wet. Make sure your
laundry is spun at the maximum spin
speed before drying. The higher the
spin speed, the greater the savings
that can be made in energy and time
during drying.
– New dark colored garments should
be washed and dried separately from
light colored garments. There is the
risk of colors running and discoloring
other garments or even plastic
components in the dryer. Dark
colored fibers can also settle on light
colored garments and vice versa.
– Starched laundry can be tumble
dried. To achieve the usual finish,
double the amount of starch should
be used.
Preparing the laundry before
drying
Damage due to foreign objects
which were not removed from the
laundry.
Foreign objects can melt, burn, or
explode.
Ensure that any foreign objects (e.g.,
detergent dispensing balls, lighters,
etc.) have been removed from the
laundry.
Risk of fire due to incorrect use
and operation.
The laundry can burn and destroy
the dryer and the surroundings.
Read and observe “IMPORTANT
SAFETY INSTRUCTIONS”.
– Sort the laundry according to the type
of fiber and weave, size, garment
care label symbol, and the drying
level required.
– Check seams and stitching to ensure
that padding and linings are intact.
This way you will avoid the danger of
fillings coming out. These could catch
fire when being dried.
– Untangle the laundry.
– Tie together textile belts and apron
ties.
– Fasten duvet covers and pillow cases
to prevent small items from being
rolled up inside them.
– Fasten hooks and eyes.
– Leave jackets open and undo any
long zippers so that textiles dry
evenly.
– Sew in or remove underwiring from
bras.
– If necessary, reduce the size of the
load for these types of fabric. Easy
care fabric tends to crease more, the
larger the load. This is particularly the
case for garments made from very
fine weave fabric, such as dress
shirts or blouses.
