and used for the first time.

M.-Nr. 06 737 050

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.

Please dispose of it at your local

community waste collection / recycling

centre and ensure that it presents no

danger to children while being stored

for disposal.

It should be unplugged or disconnected

from the mains electricity supply by a

competent person. The plug must be

rendered useless and the cable cut off

directly behind it to prevent misuse.

See the "Warning and Safety" section of

this booklet for further details.

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.

Contents

To avoid the risk of accidents and

damage to the machine please read

these instructions carefully before

using it for the first time. They

contain important information on its

safety, installation, use and

maintenance.

Keep these instructions in a safe

place and ensure that new users are

familiar with the content. Pass them

on to any future owner of the

machine.

Correct use

The tumble dryer is only intended

for drying fabrics which have been

washed in a water solution, marked on

the manufacturer's care label as being

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. The manufacturer is not

liable for damage resulting from

improper use or operation.

Technical safety

Before setting up the machine,

check it for any externally visible

damage.

Do not install or use a damaged

machine.

Before connecting the machine,

ensure that the connection data on

the data plate match the mains

electricity supply. If in any doubt,

consult a qualified electrician.

The electrical safety of this

machine can only be guaranteed

when continuity is complete between it

and an effective earthing system which

complies with 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. The manufacturer cannot be

held liable for the consequences of an

inadequate earthing system (e.g.

electric shock).

Do not connect the machine to the

mains electricity supply by an

extension lead. Extension leads do not

guarantee the required safety of the

appliance (e.g. danger of overheating).

Warning and Safety instructions

The machine is built in accordance

with current safety requirements.

Unauthorised repairs could result in

unforeseen dangers for the user, for

which the manufacturer cannot accept

liability. Repairs should only be

undertaken by a Miele approved

technician.

Ensure current is not supplied to the

machine until after maintenance or

repair work has been carried out.

Faulty components must only be

replaced by genuine Miele original

spare parts. Only when these parts are

fitted can the safety standards of the

machine 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 countries where there are areas

which may be subject to infestation

by cockroaches or other vermin, pay

particular attention to keeping the

machine 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 machine guarantee.

Warning and Safety instructions

In the event of a fault or for

cleaning purposes, the machine is

only completely isolated from the

electiricty 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 withdrawn, or

–the screw-out fuse is removed (in

countries where this is applicable).

Operation

This equipment may only be used

in mobile installations such as

ships, caravans, aircraft etc. if a risk

assessment of the installation has been

carried out by a suitably qualified

engineer.

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 thoroughly

dried after cleaning. If they are still

damp or wet when replaced there is a

risk of faults occurring when the

machine is used.

The dryer must not be used without

the condenser unit in place.

Do not install the machine in a

room where there is a risk of frost

occurring. At temperatures around

freezing point the machine 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

machine free of dust and fluff. Dust

drawn into the machine can, over time,

cause blockages in the condenser unit.

Warning and Safety instructions

To prevent the risk of fire the

following textiles must not be

dried in this machine:

–fabrics which contain a large

proportion of rubber, foam rubber or

rubber like materials.

–items which contain damaged

padding or fillings (e.g. pillows,

jackets).

–items which have been treated with

inflammable cleaning agents.

–items which have been splashed with

hair lacquer, hair spray, nail varnish

remover or similar substances.

– items which have been soiled with

oils or residues containing grease

(kitchen oils, cosmetics etc.).

– items soiled with wax or other

chemicals (e.g. mops and floor

cloths).

– items which have not been

thoroughly cleaned and which are

still soiled with grease or oil, e.g.

workwear. Such clothing may require

a heavy duty detergent to get them

clean. If necessary consult the

detergent manufacturer for advice.

Do not let anyone sit or lean on the

door, as this can cause the

machine 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.

Safety with children

This machine is not a toy. To avoid

the risk of injury keep children

away from the machine at all times and

supervise them whilst you are using it.

Do not allow children to play on or near

it or to play with its controls. Supervise

its use by the elderly or infirm.

Using accessories

Accessory parts may only be fitted

when expressly approved by Miele.

If non-Miele parts are used with this

machine, guarantee, performance and

product liability claims may be

invalidated.

Disposal of your old machine

Before discarding an old machine,

switch it off at the wall socket and

unplug it. Render the plug useless and

cut off the cable directly behind the

machine. This should be done by a

competent person.

The manufacturer cannot be held

liable for damage caused by

non-compliance with these Warning

and Safety instructions.

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.

The electronics continually assess

conditions in the machine 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.

In the same way, the Woollens

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.
