Caring for the environment

Disposal of packing material

The packing materials protect the dryer from damage during transport. They have been selected for environmental compatibility and efficient disposal and can therefore be recycled.

To prevent suffocation, ensure that any plastic wrappings, bags, etc. are disposed of safely and kept out of the reach of children.

Disposing of your old appliance

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

Ensure that a discarded dryer presents no danger to children. When being stored for disposal remove the door to the drying compartment.

Saving energy

To avoid unnecessarily long drying times and increased energy use:

Let the wash spin in the washer at

–

maximum spin speed. You can save about 30% in energy and time if you spin at 1600 instead of 800 rpm.

Use the maximum load for each

–

drying program. This gives the optimum energy consumption in relation to the total amount of laundry.

– Ensure that the room where the dryer

is located is sufficiently ventilated.

– Clean the lint screen after every use.

– Check the condenser unit from time

to time and clean it when necessary.

Description

Operating the dryer

Dear Customer,

Thank you for choosing Miele condenser (heat-exchanger) dryer!

Function of Miele condenser dryer

The condenser dryer evaporates water from damp clothes. The water vapor is then condensed and collected in a special container.

Operation of Miele condenser dryer

The condenser dryer circulates air (trapped with wet laundry inside a reversibly rotating drum) via lint filters, heat exchanger and heaters, back into the drum in a closed loop. The vapor condenses inside the heat exchanger and is collected in a condensed water container. The heat exchanger (condenser) needs cooling, so the dryer circulates ambient air, through separate channels across heat exchanger, in an open loop. (the two air flows do not mix). Returning ambient air warms up the room with dry heat. Practically all energy, taken from the electrical wall outlet, remains in the room as dry heat.

Main Features

1. No outside venting is required:

The dryer operates on heat-exchange principle.

Ideal for condominiums – needs only a regular Canadian dryer wall outlet and room air for cooling. Saves space (normally taken by a vent).

2. No depressurization,

3. No burden on dwelling’s existing

venting system,

4. High energy efficiency:

Axial air flow. Automatic moisture sensing and drying stage termination.

No venting to outside = the electrical energy is not blown outside, but stays in the room in form of dry heat (as opposed to a vented dryer).

This dry heat helps to keep a house warm in cold months. By helping to heat the house in winter, condenser dryer lowers overall energy needs of a house, thus becoming effectively more energy efficient than a vented dryer.

Description

5. Laundry care – anti-crease action

and roll-up prevention:

To limit wrinkling the dryer performs the following actions:

5.1. Tumble drying with drum reversal

(prevents roll-ups of laundry, creasing and uneven drying),

5.2. Constantly measures the

temperature of air coming into and leaving the drum,

5.3. Cycles two heater sections for 0,

half and full power, to control drum’s temperature,

5.4. Automatic drying stage

termination, after the desired Dryness level of laundry is reached,

5.5. Cooling down with tumbling and

drum reversal,

5.6. Anti-crease with drum reversal:

– axial air flow in the drum:

for uniform drying.

To do all this, the dryer is equipped with systems:

i. water conductivity metering,

ii. sensing of laundry’s residual

moisture,

iii. software,

iv. reversing drum drive.

– smooth stainless steel drum:

for air cushioning of tumbling laundry and reliable residual moisture sensing.

Program duration/ Estimated time remaining

When a program is selected, the estimated time remaining will be displayed. This is to be considered an estimate only.

In this way, the delicate and smoothing programs can end earlier, when a certain temperature is reached. This can happen with particularly fine fabrics, very small loads, or if items have previously been dried.

Delay

The delay time selected will be displayed.

The delay time countdown begins after pressing the Start button.

Once the time delay expired, the estimated program duration will appear in the display and the drying begins.

Programmable functions

The programmable functions can be used to adapt the dryer to your personal requirements. In programming mode, the display will show the function selected.

The following factors can lead to variations in the time remaining estimate: Residual moisture after spinning; type of fabric; size of load; ambient temperature, or fluctuations in the power supply.

The adaptive electronics constantly adjusts to the individual wash load to ensure a more accurate estimate of time remaining. This estimate is permanently monitored during drying, which in some cases can lead to a change in the estimate.
