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.

Installation

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 programmed 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 programmed 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 This tumble dryer is suitable for pushing under a worktop.

Appliance defect due to a build-up of heat. Make sure there is adequate room 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
The tumble dryer can also be combined 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 plinth may not be available in all countries).

Installation

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. Nonreturn 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.

Direct connection to a sink drain outlet

Use the hose holder, the hose clips and the non-return valve (available to
purchase).

1. Adapter
2. Nut
3. Hose clip
4. End of the hose (secured with the hose holder)
5. Non-return valve
6. Tumble dryer drain hose

Fit the adapter 1 to the sink drain outlet using the nut 2. The nut is usually fitted with a washer which must be removed.
Attach the end of the hose 4 to the adapter 1.
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
tumble dryer drain hose 6.

The non-return valve 5 has to be fitted so that the arrow points in the direction of flow (i.e. towards the sink).

Secure the non-return valve using hose clips.

Electrical connection

The tumble dryer is supplied with a mains cable with molded plug ready for connection to a socket.

The socket should be easily accessible after the tumble dryer has been installed. If the socket is not easily accessible, ensure that a suitable means of disconnection is provided on
the installation side for each pole.

Risk of fire from overheating.
Connecting the tumble dryer to a multi-socket plug adapter or to an extension lead can overload the cable.
For safety reasons, do not use an extension cable or multi-socket adapter.

All electrical work must be carried out
by a suitably qualified and competent
person in strict accordance with
national and local safety regulations.
For safety reasons, we recommend
using a suitable residual current device
(RCD) in the relevant electrical
installation for connecting the tumble
dryer.

If the mains connection cable is
damaged, it must only be replaced with
a specific mains connection cable of
the same type (available from Miele).

For safety reasons, such replacement
may only be carried out by a suitably
qualified and competent electrician or a
Miele authorized service technician, in
order to avoid a hazard.

The data plate indicates the nominal
power consumption and the connection
data. Compare this information with the
data of the on-site electrical
connection.

If in any doubt, consult a qualified
electrician.

Temporary or permanent operation with
a self-sufficient or non-mains
synchronous energy supply system
(e.g. isolated networks, back-up
systems) is possible. A requirement for
the operation is that the energy supply
system complies with all current local
and national requirements that apply to
stand-alone, solar and/or battery
systems.

The protective measures provided in
the domestic installation and in this
Miele product must also be assured in
their function and operation in isolated
operation or in non-mains synchronous
operation, or replaced with equivalent
measures in the installation.
