Caring for the environment

Disposal of the packing

material

The packaging is designed to protect the appliance from damage during transportation. The packaging materials used are selected from materials which are environmentally friendly for disposal and should be recycled.

Recycling the packaging reduces the use of raw materials in the manufacturing process and also reduces the amount of waste in landfill sites. 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.

Disposing of your old

appliance

Electronic and electrical appliances contain many valuable materials. They also contain certain materials, compounds and components which were essential for their correct functioning and safety. These could be hazardous to your health and to the environment if disposed of with general waste or if handled incorrectly. Please do not, therefore, dispose of your old appliance with your household waste.

Take care not to damage the tumble dryer’s pipework and heat exchanger before or during transportation to an authorised collection depot.

This is to ensure that refrigerant in the tumble dryer and oil in the compressor are contained, and will not leak into the environment.

Please dispose of it at your local community waste collection/recycling centre for electrical and electronic appliances, or contact Miele. You are also responsible for deleting any personal data that may be stored on the appliance being disposed of. Please ensure that your old appliance presents no danger to children while being stored awaiting disposal.

Warnings 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 (fuse rating, voltage and frequency) matches the mains electricity supply. If in any doubt, consult a qualified electrician.

Reliable and safe operation of this tumble dryer can only be assured if it has been connected to the mains electricity supply.

The electrical safety of this tumble dryer can only be guaranteed when correctly earthed. It is essential that this standard safety requirement is met. If in any doubt, please have the household wiring system tested by a qualified electrician. Miele cannot be held liable for the consequences of an inadequate earthing system (e.g. electric shock).

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 appliance (e.g. danger of overheating).

If the connection cable is faulty, it must only be replaced by a Miele authorised technician to protect the user from danger.

Warnings and safety instructions

Unauthorised repairs could result in unforeseen dangers for the user, for which Miele cannot accept liability. Repairs should only be undertaken by a Miele authorised service technician, otherwise any subsequent damage will not be covered by the warranty.

Faulty components must only be replaced by genuine Miele spare parts. Miele can only guarantee the safety of the appliance when Miele replacement parts are used.

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 circuit breaker.

This tumble dryer must not be installed and operated in mobile installations (e.g. on a ship).

Do not make any alterations to the tumble dryer, unless authorised to do so by Miele.

Warnings and safety instructions

This tumble dryer is supplied with a special lamp to cope with particular conditions (e.g. temperature, moisture, chemical resistance, abrasion resistance and vibration). This special lamp must only be used for the purpose for which it is intended. It is not suitable for room lighting. Replacement lamps may only be replaced by a Miele authorised technician.

This tumble dryer uses a gaseous refrigerant which is condensed by the compressor. Having been increased to a high temperature level by compression, the refrigerant passes through a closed refrigerant circuit. The heat generated is transferred to the drying air as it passes through the heat exchanger.

–The humming noises caused by the heat pump during the drying process are normal. They do not impair the correct functioning of the dryer.

–The refrigerant is environmentally friendly and does not damage the ozone layer.

Damage to the tumble dryer by switching it on too soon.

This can damage the heat pump.

After setting up the tumble dryer, wait for at least one hour before starting a drying programme.

Warnings and safety instructions

The R290 refrigerant contained in this tumble dryer is flammable

and explosive. If the tumble dryer is damaged, proceed as follows:

–Avoid naked flames or anything which creates a spark.

–Disconnect the dryer from the electricity supply.

–Air the room where the tumble dryer is located.

Risk of fire and explosion due to damage to the tumble dryer. The refrigerant is flammable and explosive if it leaks.

Take measures to protect the tumble dryer against damage. Do not

make any alterations to the tumble dryer.

Follow the instructions in “Installation” and “Technical data”.

The plug and socket must be accessible at all times in order to be able to disconnect the tumble dryer from the power supply.

Do not block the gap between the bottom of the tumble dryer and the floor with plinth facings, deep pile carpet etc. This would hinder a sufficient flow of air to the tumble dryer.

Make sure the dryer door can be opened without hindrance after installation.

Warnings and safety instructions

Correct use

Warning: Risk of fire / Flammable materials.

To avoid the possible danger of fire, please read these warnings carefully.

A clogged filter is a fire hazard!

The fluff filter must be cleaned after every programme.

The maximum load for this tumble dryer is 8.0 kg (dry weight). See the “Programme chart” for the maximum recommended loads for individual programmes.

To prevent the risk of fire, do not connect the tumble dryer via a controllable socket (e.g. a timer or a peak-load switch-off device). If the drying programme is interrupted before the end of the cooling down phase, this could cause the laundry to self-ignite.

Warning: Ensure that you always wait until the end of the programme before removing the laundry. If the drying programme is stopped prematurely, remove the laundry immediately and hang it up or spread it out to cool it down.

Fabric softener and similar products must be used according to the instructions on the manufacturer's packaging.

Remove all items from pockets (e.g. lighters, matches).

The fluff filters must be cleaned after every drying cycle.

Fluff must not be allowed to accumulate around the tumble dryer.

Warnings and safety instructions

The fluff filters and the plinth filter must be thoroughly dried after cleaning. Do not replace them if they are damp or wet. Damp or wet filters could cause operational faults.

Oil-affected items can ignite spontaneously, especially when exposed to heat sources such as in a tumble dryer.

The items become warm, causing an oxidation reaction in the oil. Oxidation creates heat.

If the heat cannot escape, the items can become hot enough to catch fire. Piling, stacking or storing oil-affected items can prevent heat from escaping and so create a fire hazard.

If it is unavoidable that fabrics contaminated with vegetable or cooking oil, or hair care products, be placed in a tumble dryer, they should first be washed in hot water with extra detergent - this will reduce, but not eliminate, the hazard.

To prevent the risk of fire, textiles that have not been cleaned thoroughly or are still soiled with deposits of any kind must not be dried in this tumble dryer. This applies in particular to

–Items which have not been washed.

–Items, such as workwear, which have not been thoroughly cleaned and are still soiled with grease, oil or other deposits (such as cooking oils, cosmetics, lotions, etc.). If items have not been thoroughly cleaned, there is a danger that they might 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) that have been treated with inflammable cleaning agents or which contain residues of acetone, alcohol, benzene, petrol, kerosene, stain remover, turpentine, wax and wax remover or other chemicals.

–Items which have been splashed with hair lacquer, hair spray, nail varnish remover or similar substances.

Warnings and safety instructions

When washing such heavily soiled items:

Ensure that you use a larger quantity of detergent and select a high temperature. If in doubt, wash the items several times.

To prevent the risk of fire, the following textiles must never be dried in the tumble dryer:

–Textiles that have been cleaned using chemicals (e.g. professional dry-cleaning agents).

–Textiles 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.

–Textiles which contain padding or fillings which are damaged (e.g. pillows, jackets). The filling could fall out and cause a fire.

The heat pump that is essential to the operation of this tumble dryer generates a lot of heat inside its casing. It must be possible to dissipate this heat well. Otherwise loads could take longer to dry or the tumble dryer might sustain damage in the long term.

The following mandatory requirements must be met:

–permanent room ventilation from the beginning to the end of every drying programme.

–a gap between the floor and the bottom of the tumble dryer (this must not be blocked or obstructed in any way).

The tumble dryer must not be hosed down.

Do not let anyone sit or lean on the door, as this can cause the tumble dryer to tip up.

Warnings and safety instructions

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 selfigniting). 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.

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 used

–without the fluff filters in place or with damaged fluff filters.

–without the plinth filter in place or with a damaged plinth filter.

This would cause an excessive build-up of fluff which in turn would

cause a fault.

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 hoses.

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 laundry tub 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 heat exchanger over time.

Warnings and safety instructions

Using a fragrance flacon (optional accessory)

Only use genuine Miele original fragrance flacons.

The fragrance flacon must be stored in its packaging so please make sure you retain this.

Caution. The fragrance can run out of the flacon. Make sure that you always keep the flacon, or the fluff filter with the flacon inserted in it, upright when carrying and do not tip it or place it down on any surface.

Use an absorbent cloth immediately to wipe up any fragrance which has run out of the flacon onto the floor, the dryer or any dryer components (e.g. the fluff filter).

If fragrance which has run out of a flacon should come in contact with the skin - wash the skin thoroughly with soap and water; come in contact with the eyes - rinse the eyes with clean water for at least 15 minutes; be swallowed - rinse out the mouth thoroughly with clean water. Seek medical advice in the case of contact with the eyes or if fragrance has been swallowed.

If fragrance which has run out of a flacon comes in contact with clothing, change the clothing immediately. Wash the clothing or any cloths used for mopping up fragrance thoroughly with plenty of water and detergent.

There is the risk of fire or damage to the tumble dryer if the following instructions are not observed:

–Never refill a flacon with fragrance.

–Never use a faulty fragrance flacon.

Dispose of an empty fragrance flacon with the household waste and never use it for any other purpose.

Please also observe the information supplied with the fragrance flacon.

Warnings and safety instructions

Accessories

Only use genuine Miele spare parts and accessories with this appliance. If spare parts or accessories from other manufacturers are used, this will invalidate the warranty, and Miele cannot accept liability.

A Miele tumble dryer can be stacked on top of a Miele washing machine using the appropriate stacking kit (available as an optional accessory). Please make sure you order the correct one for the Miele washing machine and Miele tumble dryer.

Miele cannot be held liable for damage caused by noncompliance with these Warning and Safety instructions.

Damage to the tumble dryer by switching it on too soon.

This can damage the heat pump. After setting up the tumble dryer, wait for at least one hour before switching it on.

Removing the protective foil

and stickers

Remove:

–the protective foil from the door

–any stickers 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.

Follow the procedure for using

for the first time outlined in

these instructions

Refer to “1. Notes on correct laundry care” and “2. Loading the tumble dryer”.

You can then load the tumble dryer and select a programme as described in “3. Selecting a programme and starting it”.

Energy saving tips

This dryer with heat-pump technology is designed for energy-saving drying cycles. You can save even more energy with the following measures, because 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 spinning laundry at 1600 rpm instead of 1000 rpm.

–Use the maximum load quantity for the drying programme being used. This will mean that the energy consumption for the amount of laundry is the 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 fluff filters in the door opening after every drying cycle.

Please refer to “Cleaning and care” for information on cleaning the fluff filters and the plinth filter.

–If possible, make use of timevariable, low-cost electricity tariffs. Ask your energy supplier for information. Your tumble dryer's Delay start function will be useful as you can select when during the next 24 hours you want drying to start automatically.

1. Notes on correct laundry care

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 put soaking wet items into the tumble dryer. Make sure your laundry is thoroughly spun before drying. The higher the spin speed, the greater the savings that can be made in energy and time during drying.

–New dark coloured garments should be washed and dried separately from light coloured garments to avoid the risk 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.

–Starched laundry can be dried in the tumble dryer. 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. See “Warning and Safety instructions” for further information.

–Sort the laundry according to the type of fibre 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 zips so that textiles dry evenly.

–Sew in or remove loosened underwiring from bras.

–Reduce the size of the load. Minimum iron fabric tends to crease more the larger the load. This is particularly the case for garments made from very fine weave fabric, such as shirts or blouses.

1. Notes on correct laundry care

Drying

Useful tip: See the “Programme chart”. It lists all programmes and their maximum load.

–Always observe the maximum recommended load for each programme. This will mean that the energy consumption for the amount of laundry is the most economical.

–Down-filled garments have linings which have a tendency to shrink, depending on the quality of the item. Only use the Pre-ironing programme for these textiles.

–Pure linen should only be tumble dried if it is specified as suitable on the care label. The surface of the fabric may otherwise become rough. Only use the Pre-ironing programme for these textiles.

–Woollens and wool blends are susceptible to becoming matted or shrinking. Only use the Woollens handcare programme for these textiles.

–Loopknit garments (e.g. T-Shirts, underwear) have a tendency to shrink after the first wash. Do not overdry these fabrics to prevent further shrinking. When buying loopknit garments, it is advisable to take their shrinkage potential into account.

–With fabrics that are particularly heatsensitive or susceptible to creasing, reduce the drying load and select

Gentle tumble.
