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.

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.

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.
–smooth stainless steel drum:
for air cushioning of tumbling
laundry and reliable residual
moisture sensing.
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.
