Installation notes

Installation requirements

Risk of injury or damage to property due to improper installation.
Incorrect installation of the tumble dryer can lead to personal injury or damage to property.
The tumble dryer must only be installed and commissioned by Miele Customer Service Department or an authorised dealer.

• The tumble dryer must be installed in accordance with all relevant regulations and standards.
• The dryer must only be operated in a room that has sufficient ventilation and which is frost-free.
• The tumble dryer must not be installed behind a close able door or a sliding door. The maximum opening angle of the tumble dryer door must not be limited by objects or doors.
  It must be possible to fully open the tumble dryer door at any time.

Electrical connection

The electrical connection must be established by a qualified electrician.

• The electrical connection may only be made to an electrical system provided in accordance with all appropriate local and national legislation, regulations and guidelines. Please also observe the regulations set out by your insurance provider and energy supplier, accident prevention regulations, as well as recognised codes of practice.

• Reliable and safe operation of this tumble dryer is only ensured if it has been connected to the mains electricity supply.
  The required supply voltage, power rating and fuse rating can be found on the data plate on the tumble dryer. Ensure that the supply voltage matches the voltage quoted on the data plate before establishing the electrical connection to the tumble dryer.
  Connection to a supply voltage other than the one quoted on the data plate can damage the tumble dryer if the voltage is too high.

• If more than one voltage is specified on the data plate, the tumble dryer can be converted for connection to the relevant input voltage. This conversion must be performed by the Miele Customer Service Department or by an authorised dealer. During the conversion, the wiring instructions given on the wiring diagram must be followed.

Tip: We recommend connecting the tumble dryer to the power supply via a plug and socket so that it is easier to conduct electrical safety checks (e.g. during maintenance or repair work).

It is recommended the tumble dryer is connected with a suitable plug and socket in accordance with IEC 60309-1, however if the installation requires a hard-wired connection, an allpole means of isolation must be provided onsite. Switches with a minimum contact gap greater than 3 mm are suitable disconnectors. These include circuit breakers (MCB), fuses and contactors (VDE 0660) (IEC/EN 60947)

If the mains supply cannot be permanently disconnected, the isolation device (including plug and socket) must be safeguarded against being switched on either unintentionally or without authorisation.

• The tumble dryer must not be connected to devices such as timers which would switch it off automatically.

If local regulations require that a residual current device (RCD) is installed, a type B residual current device (sensitive to universal current) must be used.

• If local and national installation specifications require potentiality bonding, good galvanic contact must be guaranteed. Potentiality bonding must have an earth current rating > 10 mA.

Loud noises and risk of damage due to incorrect phase connection on heat-pump dryers.
An incorrect phase position causes a lot of noise in tumble dryers with heat pumps and can cause damage to the compressor.
When connecting a heat-pump dryer to the power connection, ensure the correct phase position according to the wiring diagram.

Peak-load negotiation

The heat-pump dyer can be connected to peak-load negotiation if this is required. However, this is not essential, as the heat-pump dryer has been designed for very low energy consumption.

Depending on the function, switching off the appliance externally during the drying process when the heat-pump is in use can reduce the service life of the appliance.
Please note that if it is connected to peak-load negotiation, the heat-pump dryer must not be switched off.

Information on operating status is made available via the Miele peak-load interface. Please note that the energy requirement of all appliances that cannot be switched off in the energy management system must be stored by the control system.

Air intake vent

The air supply for the cooler is drawn in through the air intake vent on the front of the machine directly from the room in which the dryer is installed.

There is a fluff filter in the dryer’s air intake vent which must be def luffed regularly by hand.

The air intake vent must always be kept clear. It must not be covered.

Air outlet vent

Separate vent ducting is not required for the heat pump dryer due to the closed air circuit.

The hot air that is blown out from the heat exchanger to cool it warms the room air. Therefore, ensure sufficient room ventilation, e.g. by means of ventilation openings that cannot be closed. If the room is not sufficiently ventilated, the drying time will be longer, which will also increase the energy requirement of the dryer.

The air outlet vent must never be closed or covered by objects.

Condensate drainage

The heat pump in this tumble dryer operates according to the principle of condensation. A separate floor drain must be provided in the installation room for condensate produced during the drying process.

The condensate drainage point is located at the back of the heat-pump dryer. The condensate must be drained to the floor drain via a DN 30 pipe pointing downwards.

It must be ensured that condensate cannot flow back into the dryer.
Any condensate that gets back into the machine can cause damage.

Technical data

Possible voltage variants

Standard connection

Supply voltage| 3N AC 400 V
Frequency| 50 Hz
Power rating| 5.1 kW
Fuse rating (on site)| 3×16 A
Minimum cross-section for connection cable| 5×2.5 mm²

Peak-load negotiation (optional)

Miele recommends using a flexible connection cable with an additional isolation option to establish the connection. The Solaris should remain visible once the tumble dryer has been installed and must be freely accessible.

Condensate drainage

Condensate connector on machine side (external diameter): 30 mm

The tumble dryer with heat pump operates according to the principle of condensation. The condensate that accumulates must be drained away separately via a floor drain. The water can be routed to the floor drain via a hose or pipe pointing downwards.

Pensioning strips| 2|
Wood screws DIN 571 (Ø × length)| 2| Screw size
Plugs (Ø × length)| 2| 10×50 mm

If the tumble dryer is being installed without a plinth, fixing it in place is recommended.
Fastenings for floating screed must be supplied by the customer on site.

Fixing to concrete plinth
