Caring for the environment

Disposal of the packing
material

The transport and protective packing
has been selected from materials which
are environmentally friendly for disposal
and can normally 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!

Rather than just throwing these
materials away, please ensure they are
offered for recycling.

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 of your
appliance with your household waste.

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.

Please dispose of it at your local
community waste collection / recycling
centre or contact your Dealer for
advice. Ensure that it presents no
danger to children while being stored
for disposal.

Warning and Safety instructions

Correct application

This tumble dryer is for domestic

~

use only and can only be used to dry
items which have been washed in a
water solution and which are marked on

It is essential to read these

~

instructions.

This tumble dryer conforms to
current safety requirements.
Inappropriate use can, however,
lead to personal injury and damage
to property.

To avoid the risk of accidents and
damage to the tumble dryer, please

suitable for tumble drying. "Dry
cleaning kits" for freshening up
garments in a tumble dryer are
increasingly available on the market. If
using, do so at your own risk, and
follow the instructions provided on the
packaging.
Any other applications may be
dangerous. Miele cannot be held liable
for damage resulting from incorrect or
improper use or operation.

This appliance is not intended for

~

use by persons (including children)
with reduced physical, sensory or
mental capabilities, or lack of
experience or knowledge, unless they
are supervised whilst using it or have
been shown how to use it by a person
responsible for their safety.

Safety with children

Keep children away from the tumble

~

dryer at all times. It is not a toy! To
avoid the risk of injury do not allow
them to play on or near it or to play with
its controls. Supervise children whilst
you are using it.

6

Warning and Safety instructions

Technical safety

Before setting up the tumble dryer,

~

check it for any externally visible
damage.
Do not install or use a damaged tumble
dryer.

Before connecting the tumble dryer,

~

ensure that the connection data on the
data plate (voltage and connected
load) match the mains electricity
supply. If in any doubt, consult a
qualified electrician.

The electrical safety of this tumble

~

dryer can only be guaranteed when
continuity is complete between it and
an effective earthing system which
complies with current local and national
safety regulations. It is most important
that this basic safety requirement is
present and regularly tested, and
where there is any doubt the household
wiring system should be inspected by a
qualified electrician. Miele cannot be
held liable for the consequences of an
inadequate earthing system (e.g.
electric shock).

Faulty components must only be

~

replaced by genuine Miele original
spare parts. Only when these parts are
fitted can the safety standards of the
tumble dryer be guaranteed.

If the connection cable is faulty it

~

must only be replaced by a Miele
approved service technician to protect
the user from danger.

In the event of a fault or for cleaning

~

purposes, the tumble dryer is only
completely isolated from the electricity
supply when:

– it is switched off at the wall socket

and the plug is withdrawn, or

– it is switched off at the mains, or

– the mains fuse is disconnected, or

– the screw-out fuse is removed (in

countries where this is applicable).

This tumble dryer may only be used

~

in mobile installations such as ships if a
risk assessment of the installation has
been carried out by a suitably qualified
engineer.

Do not connect the tumble dryer to

~

the mains electricity supply by an
extension lead. Extension leads do not
guarantee the required safety of the
tumble dryer (e.g. danger of
overheating).

Unauthorised repairs could result in

~

unforeseen dangers for the user, for
which Miele cannot accept liability.
Repairs should only be undertaken by a
Miele approved service technician.
Ensure current is not supplied to the
tumble dryer until after maintenance or
repair work has been carried out.

In countries where there are areas

~

which may be subject to infestation by
cockroaches or other vermin, pay
particular attention to keeping the
tumble dryer and its surroundings in a
clean condition at all times. Any
damage which may be caused by
cockroaches or other vermin will not be
covered by the guarantee.

Do not make any alterations to the

~

tumble dryer, unless authorised to do
so by Miele.

7

Warning and Safety instructions

Correct use

To prevent the risk of fire, the

~

following textiles must not be dried in
this tumble dryer:

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 ignite when heated, even after
they have been removed from the
dryer at the end of the programme.

– items (e.g. mops and floorheads)

which have been treated with
inflammable cleaning agents or
contain residues of acetone, alcohol,
benzine, petrol, 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 sufficient
detergent and select a high
temperature. If in doubt, wash the
items several times.

To prevent the risk of fire, the

~

following must not be dried in this
tumble dryer:

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 dryer.

In many programmes, the heating

~

phase is followed by a cooling down
phase to ensure that the items 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.
Ensure that you always wait until the
end of the programme before removing
the laundry.

Warning: Do not switch the tumble

~

dryer off before the end of the drying
programme. If this was done and the
laundry was then removed immediately
it could give off a great amount of heat.

Fabric conditioner and similar

~

products must be used according to
the instructions on the manufacturer's
packaging.

8

Warning and Safety instructions

The 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 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, hoses and / or condensed
water container.
The ambient room temperature should
be between +2°C and +35°C.

If the water is drained externally

~

through the drain hose 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
drawn into the tumble dryer can cause
blockages in the condenser unit over
time.

Do not let anyone sit or lean on the

~

door, as this can cause the tumble
dryer to tip up.

Always close the door after use. This

~

way you will avoid the danger of:

children climbing onto or into the

–

dryer or hiding things in it.

pets or other small animals climbing

–

into it.

The tumble dryer must not be hosed

~

down.

Accessories

Only use genuine Miele spare parts

~

and accessories with this appliance.

Programme duration / Estimated time
remaining

When a programme is selected, the
estimated duration (time remaining) will
appear in the display. Please be aware
that it is only an estimate.

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.

In the same way, the Woollens

handcare, Silks handcare and
Smoothing programmes can finish

earlier than expected if a certain
temperature is reached. This can
happen with particularly fine fabrics,
very small loads or if items were partly
dry beforehand.

Delay start

The delay start time selected will
appear in the display.

After the Start/Stop button has been
pressed, the delay start time will start
counting down.

Once the delay start time has elapsed,
the programme will begin and the
estimated programme duration will
appear in the display.

Programmable functions

The programmable functions can be
used to tailor drying programmes to suit
your individual requirements. In
programming mode, the display will
show the function selected.

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.
