READ AND SAVE THESE INSTRUCTIONS

Proper use of the dryer

The dryer is only intended for drying fabrics that were

washed in water. Check fabric care labels to verify that the articles can be machine dried.

To prevent fire, do not dry the following (with the

exception of the textiles permitted in the special programs):

Articles containing foam rubber, rubber or rubber-like

–

materials.

Articles that have been treated with flammable cleaning

–

agents.

Articles that have been contaminated with styling

–

creams, hair spray, nail polish remover, etc.

Articles that may be greasy, oily or that may contain

–

other residues, e.g. kitchen or salon laundry.

Mops, floor cloths, etc. if they contain substances such

–

as wax or chemical cleaning agents.

Damaged padded or filled fabrics such as jackets or

–

cushions.

Articles that are not sufficiently clean and are soiled with

–

grease or oil. Wash very dirty articles (e.g. work clothing) with a special detergent. For information in this regard, consult a cleaning agent retailer.

Keep these operating instructions in a safe place and pass them on to any future user.

Read all instructions before installation or use of the dryer to prevent injury and machine damage.

Installation, repair and maintenance work should be performed by a Miele authorized service technician. Work by unqualified persons could be dangerous

Improper use of the appliance can lead to personal injury and material damage.

All personnel working with this machine must be fully trained in all aspects of its use and safety.

– With these critical fabrics the laundry may

spontaneously combust. Immediately remove the laundry at the end of the drying program and after a power failure. Keep a fire extinguisher near the dryer.

The laundry must not be removed from the dryer until

the cooling down phase has been completed. If hot laundry items are stacked or packed they could spontaneously combust.

Empty all pockets so that no flammable items such as

lighters, matches, candles and cosmetics end up in the dryer.

If the dryer is operated in an area accessible to the

public, the operator must ensure that the appliance can be used safely.

This dyer is not intended for outdoor use.

IMPORTANT SAFETY INSTRUCTIONS

Technical and electrical safety

The dryer must be installed and tested by Miele's

Technical Service Department or an authorized dealer.

The electrical safety of this appliance is only assured if it

is connected to a grounding system. Is is very important to make sure that this essential safety requirement is met. If in doubt have the house wiring system checked by a qualified electrician. The manufacturer will not be held liable for damage caused by a missing or improperly connected ground wire.

The dryer is disconnected from the power supply only

when it is unplugged or when the main breaker or the dryer's breaker at the building's electrical service panel is switched off.

Unprofessional repairs may create unforeseeable risks

for the user, for which Miele assumes no liability. Repairs should be carried out only by authorized Miele technicians

- otherwise, associated damage will not be covered by the warranty.

Defective components must be replaced with genuine

Miele spare parts only. Only with these parts can we guarantee that the safety requirements of our appliances are met.

Do not operate the dryer in a room where cleaning

machines operate with solvents containing CFC. Vapors from combustion turn into hydrochloric acid which damages laundry and dryer. When operated in a separate room, there must be no air exchange.

Make sure the dryer is supplied with clean fresh air only,

not air containing chlorine, fluorine or other solvent vapors.

The cool air intake opening is located on the back of the

dryer, while the exhaust air opening is located on the cover. Never block these openings. Therefore, do not cover the top of the dryer with any type of blankets, sheets or boxes (see installation instructions).

Never use or store gasoline, petroleum-based

substances or other easily flammable substances near the machine. Fire and explosion hazard!

The dryer needs timely and professional maintenance to

prevent performance loss, malfunctions and the risk of fire.

Use of the appliance

The dryer is only intended for drying fabrics that

were washed with water as a cleaning agent.

Operate the dryer only if an exhaust air duct is

connected and the room is adequately ventilated.

The dryer may be operated only if the heat pump

module is hooked up and connected to the dryer. Sufficient ventilation must be ensured (see the installation instructions).

Make sure that the heat pump is correctly connected to

the dryer without any gaps. It must not be possible to reach between the two machines - risk of injury!

Persons who lack physical, sensory or mental abilities,

or experience with the appliance should not use it without supervision or instruction by a responsible person.

Do not let children play in, on or near the dryer. Do not

let them play with the controls or operate the unit.

Make sure that no unattended children can access the

machine. There is a potential danger that children can be trapped in the drum. This may cause major injuries or the death of the child.

Do not operate the appliance if the control panel, wires

or cables are damaged.

Do not damage, remove, or bypass any of the safety

features and controls of the dryer.

Do not operate the dryer when housing parts have been

removed and the moving or electrical parts are exposed and accessible.

High temperatures occur at the window and frame of

the drum door, and the laundry is extremely hot if it is removed too soon.

Always make sure the drum is stationary before

reaching in to remove laundry. Never put your hand into a drum that is still moving.

Take care not to pinch or cut your fingers on the hinges

of the drum door or lint flap and on the maintenance cover on the back of the dryer. Use the handles and quick release fasteners. Beware of any potential hazardous areas when installing the dryer and heat pump.

The area necessary to open the drum door completely

must not be obstructed by doors or other structures.

IMPORTANT SAFETY INSTRUCTIONS

Do not use the dryer without the built-in lint filter in

place. Fire hazard! If the lint filter is damaged it must be replaced immediately. A build-up of lint will block the airflow and heating,

which will impair the efficiency of the dryer.

Disinfection and cleaning agents often contain chlorine

compounds. If these agents dry on stainless steel, the chlorides may attack the stainless steel and cause it to rust. To protect the dryer from rusting, use only chlorine-free disinfection and cleaning agents for laundering and disinfecting, and for cleaning the stainless steel surfaces. If in doubt about a cleaning agent, contact the manufacturer. If an agent containing chlorine is spilled, wash it off with water and dry with a soft cloth.

Do not use a power washer or water jet to clean the

dryer. Only the heat exchangers and the space between the maintenance flap (access via quick release fasteners on the back of the dryer) may be rinsed out with a jet of water (max. 4 bar).

Following operation, refrigerant lines and the

neighboring components may pose hazards in the form of hot or cold surfaces and pressurized parts. Do not open any cover parts until the system has had sufficient time to cool down.

Using accessories

Only accessories expressly allowed by Miele may be

installed. Adding or installing other parts will void any warranty and/or product liability claims.

Disposing of the appliance

If you are disposing of an old dryer (scrap metal

collection), destroy the door latch. This will prevent children from accidentally locking themselves in, which would place them at risk of death.

SAVE THESE

INSTRUCTIONS

Precautionary measures for dealing with a loss of refrigerant

The heat pump refrigeration circuit contains a non-toxic,

odorless refrigerant (R134a) that quickly evaporates when released. In vapor form it is heavier and air and poses a suffocation hazard in unventilated rooms!

If you notice any damage to the copper lines on the

heat pump, do not operate the machine and exit the room.

–

Notify any other persons present of the danger.

–

Please refer to the safety data sheet for further information on handling refrigerant.

Caring for the environment

Disposal of packing materials

The packing materials are intended to protect the machine from damage during shipping. They have been selected for environmental compatibility and efficient disposal and can therefore be recycled. Returning packaging to the materials cycle saves raw material and reduces waste. The packing materials can be returned to your dealer.

Keep packing materials such as shrink wrap

and plastic bags away from children because of the danger of suffocation.

Disposal of the appliance

Appliances may contain materials that can be recycled. Please contact your local recycling authority about the possibility of recycling these materials.

Please make sure that you dispose of your old appliance in accordance with regional disposal regulations and prevent an uncontrolled release of refrigerant into the environment.

Ensure that the appliance presents no danger to children while being stored for disposal. Before discarding an old appliance, unplug it from the outlet, cut off its power cord, remove any doors to prevent hazards. and store appliance on side to prevent tipping. For more information see the "IMPORTANT SAFETY INSTRUCTIONS".

Information on saving energy

You have purchased a heat pump dryer featuring the latest technology. This dryer uses 50% less energy than conventional dryers with electric heating. The following tips will help you further lower your energy consumption:

Wash your laundry on maximum spin cycle speed. This will reduce drying time and energy consumption.

If the washing machine's last rinse cycle is with warm water, a shorter drying time will be required due to the lower residual moisture and the residual heat in the laundry, which in turn saves energy.

Sort fabrics:

- by fiber/weave,

- by desired drying level,

- by residual moisture.

Only dry full loads, if possible. Under-loading is not cost efficient. Overloading provides poor drying results and has an adverse effect on fabrics. Optimal energy consumption is relative to the total amount of laundry.

A free lint filter and clean heat exchangers increase the efficiency of the system and the drying process, thereby reducing runtime and energy required.

Ensure sufficient room ventilation.

Drying

Before first use

Wipe the interior of the drum with a soft dry cloth

Preparing the laundry

Not all fabrics are suitable for drying in a

tumble dryer. Check the manufacturer’s instructions on the fabric care label.

q = Dry at normal temperature r = Dry at low temperature s = Do not tumble dry

Sort the laundry by fabric type and color. This will

ensure even drying results and will prevent damage to fabrics.

To prevent fire, do not dry the following

(with the exception of the textiles permitted in the special programs):

Articles containing foam rubber, rubber or rubber-like materials.

Articles that have been treated with flammable cleaning agents.

Articles that have been contaminated with hair spray, nail polish remover, etc.

Articles that may be greasy, oily or saturated with other residues, e.g. kitchen or salon laundry.

Important drying information:

Articles made from pure wool and wool mixtures

–

may become matted. Dry these with the Woolens program only.

Pure linen may become rough with tumble drying.

–

Consult the manufacturer’s instructions before drying.

Items with metal buckles, hooks, snaps, zippers,

–

etc. should be put into the dryer in a cloth bag (e.g. pillow case) to protect the drum from scratches and dents.

Articles with closed metal zippers may cause a

–

short at the sensor electrodes on the drum ribs, so that the drying process ends too late or does not end at all. These items should be dried with the zippers open.

Loop knit materials tend to shrink. Over-drying

–

increases this effect. Do not use the highest dry program for such fabrics.

Starched laundry can be tumble dried. Select a

–

program with a suitable residual moisture for ironing by hand or machine. Sort the laundry according to the level of dryness required. It is not necessary to sort according to size.

– Pillow cases and duvet covers should be buttoned

to prevent smaller items from getting caught inside them.

– For cost efficiency, only dry full loads. Overloading

provides poor drying results and has an adverse effect on fabrics.

Mops, floor cloths, etc. if they contain substances such as wax or chemical cleaning agents.

Damaged padded or filled fabrics, like jackets or cushions.

Articles that are not sufficiently clean and are soiled with grease or oil. Wash very dirty articles (e.g. work clothing) with a special detergent.

–

If the washing machine's last rinse cycle is with warm water, a shorter drying time will be required due to the lower residual moisture and the residual heat in the laundry.
