Transporting the tumble dryer
Danger of injury to people and
damage to property caused by
moving the appliance incorrectly.
If the tumble dryer tips over, there is
a danger of injury to people and
damage to property.
Ensure that the tumble dryer is stable
during transportation.
If the tumble dryer is being
transported horizontally, it must only
be tipped onto its left or right side.
If the tumble dryer is being
transported upright and you are using
a handcart or trolley, you must only
transport it with its left or right side
resting on the handcart or trolley.
Transporting the tumble dryer to its
installation site
Make sure the fixings at the back
of the lid are secure.
Otherwise there is a danger of the lid
being pulled off when carrying the
appliance.
Before carrying the appliance, check
that the lid is secure where it
protrudes at the back of the
appliance.
Carry the tumble dryer by the front
feet and by the lid where it protrudes
at the back of the appliance.

Installation
Levelling the dryer
The appliance must not be installed
behind a lockable door, a sliding
door or a door with a hinge on the
opposite side to that of the tumble
dyer, in such a way that a full
opening of the tumble dryer door is
restricted.
To ensure proper operation, the tumble
dryer must stand perfectly level. The
screw feet on the tumble dryer can be
adjusted to compensate for unevenness
in the floor.
Turn the screw feet by hand or with a
flat open spanner.
Risk of fire and explosion due to
damage to the tumble dryer.
The refrigerant is flammable and
explosive.
Do not make any alterations to the
tumble dryer. Take measures to
protect the tumble dryer against
damage.
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.
- Contact Miele Customer Service.
Downtime after installation
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.

Ventilation
The cool air intake at the front of the
tumble dryer must not be blocked or
covered. This would hinder a
sufficient intake of cool air for the
heat exchanger.
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.
Adequate ventilation has to be
provided to avoid the backflow of
gases into the room from appliances
burning other fuels, including open
fires.
Air which is taken in to cool the heat
exchanger is then blown back out of the
dryer and warms up the air in the room.
Ensure sufficient ventilation of the
room, e.g. by opening a window. The
drying time will otherwise take longer
(higher energy requirement).
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.
Permanent room ventilation during
every drying programme and the
ventilation gap between the bottom
of the tumble dryer and the floor are
mandatory requirements at all times.
Before moving the tumble dryer
again (e.g. when moving house)
A small quantity of condensed water
that remains in the area around the
pump after the drying process can run
out if the tumble dryer is tilted.
Recommendation: start a programme
for approx. 1minute before transporting
the dryer. Any remaining condensed
water will then be fed into the
condensed water container (which you
will need to empty again) or out through
the drain hose.

Additional installation
requirements
Suitable for pushing under a worktop

for warm air from the dryer to be
directed away.
- The appliance lid cannot be removed.
- The electrical socket must be located
in an accessible position near the
appliance.
- Drying durations may increase
slightly.
Optional accessories
– Washer-dryer stack

with a Miele washing machine in a
washer-dryer stack. The appropriate
Miele washer-dryer stacking kit is
required.
– Plinth
The tumble dryer can be fitted with a
plinth with drawer (please note the

Externally draining condensed
water
Notes
When drying is in progress,
condensed water is pumped into the
condensed water container through
the drain hose which is located at the
back of the dryer.
The condensed water can also be
drained away via the drain hose. The
condensed water container will then not
need to be emptied.
Hose length: 1.49m
Maximum delivery head: 1.00m
Maximum drain hose length: 4.00m
Drainage accessories
- Supplied: adapter (b), hose clip (c),
hose holder (e);
- Available to purchase: “Non-return
valve” kit for connection to an
external water connection. Non-
return valve (d), hose extension (a)
and hose clips (c) are supplied with
the kit.
Installation conditions requiring a
non-return valve
Danger of condensed water
backflow.
Water could flow back into the
tumble dryer or be drawn into it.
Backflow water could damage the
tumble dryer and also the room in
which it is located.
The non-return valve should be used
if the end of the hose is immersed in
water, or if other water connections
are installed.
Maximum delivery head with non-return
valve fitted: 1.00m
Installation conditions requiring the
fitting of a non-return valve:
- Drainage into a laundry tub or floor
gully where the end of the hose is
immersed in water.
- Connection to a sink drain outlet.
- Connection to a drainage system
already in use by another appliance,
e.g. a dishwasher or washing
machine.
If the non-return valve is incorrectly
fitted the appliance will not drain.
The non-return valve has to be fitted
with the arrow on it pointing in the
direction of flow.

Arranging the drain hose
Damage to the drain hose
through incorrect handling.
The drain hose can suffer damage
and leak.
Do not pull on the drain hose and do
not stretch it or allow it to become
kinked.
There will be a small amount of residual
water left in the drain hose. Have a
container ready to collect this.
Pull the drain hose off its connection
(light arrow).
Pull the hose out of the holders (dark
arrows) and unwind it.
Allow any residual water to run into a
container.
Examples
Drainage into a laundry tub or floor gully
Use the hose holder to secure the drain
hose.
Risk of water damage.
Should the end of the hose come
loose, overflowing water can cause
damage.
Secure the drain hose carefully (e.g.,
by tying it) to make sure it cannot
slip.
The non-return valve can be fitted in the
end of the hose.

Use the hose holder.
Use a screwdriver to tighten the hose
clip 3 up close to the nut.
Fit the non-return valve 5 to the
