Installation notes

Installation requirements

The tumble dryer must only be installed and commissioned by Miele Customer Service Department or an authorized 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.

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 recognized 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 authorized dealer. During the conversion, the wiring instructions given on the wiring diagram must be followed.
The tumble dryer can either be hard-wired or connected using a plug-and-socket connection in accordance with IEC 60309-1. For a hard-wired connection, an all-pole isolation device must be available at the installation site.

An isolation device is a switch that ensures a contact opening of more than 3 mm. These include circuit breakers, fuses, and contactors (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 authorization.

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).
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 equipotential bonding, good galvanic contact must be guaranteed.  Equipotential bonding must have an earth current rating > 10 mA.
Air intake/exhaust air
The tumble dryer may only be operated when the ducting has been connected properly and the room is sufficiently ventilated.
Accessory parts may only be fitted when expressly approved by Miele. If other parts are used, warranty, performance, and product liability claims will be invalidated.

Technical data

Voltage variants/electrical data
Voltage variant 1

| Standard connection
---|---
Supply voltage| 3N AC 400 V
Frequency| 50/60 Hz
Power rating| 23.5 kW
Fuse rating (on-site)| 3×50 A
The minimum cross-section for the connection cable| 5×10 mm²
Cable gland| M40

Voltage variant 2

| Standard connection
---|---
Supply voltage| 3 AC 230 V
Frequency| 50/60 Hz
Power rating| 23.5 kW
Fuse rating (on-site)| 3×63 A
The minimum cross-section for the connection cable| 4×16 mm²
Cable gland| M40

Exhaust air

The maximum nominal volume flow rate in extraction mode (PDR 9xx only)| 960 m³/h
---|---
Maximum nominal volume flow rate (PDR 5xx only)| 740 m³/h
The maximum permitted pressure loss| 350 Pa
Connector on machine side (external diameter)| 150 mm
Connection pipe provided on-site (internal diameter)| 150 mm
Maximum exhaust air temperature| 80 °C
As relative humidity inside the exhaust ducting can be as high as 100 %, suitable measures must be taken to prevent a backflow of condensate into the machine.

Air intake

Standard connection: air intake from the installation site
Recommended free air intake cross-section into the room: (equivalent to 3 times the exhaust air cross-section of a machine).
There must be sufficient air intake to the installation site to match the air outlet volume.| 531 cm²
---|---
Alternative connection: air intake connection directly from outdoors
Connection sleeve on machine side (internal diameter)
Connection pipe provided on-site (external diameter)| 161 mm
160 mm
Removing the protective cover exposes live parts. For safety reasons, a pipe must be installed from the tumble dryer’s central fresh air intake (over a minimum length of 900 mm) and secured with 2 screws.|

Equipotential bonding (optional)

Accessories for equipotential bonding are not supplied and need to be ordered separately.

Peak-load negotiation (optional)

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

Fixing options

Fixing without plinth

| Quantity| Screw size
---|---|---
Tensioning strips| 2|
Wood screws DIN 571 (Ø × length)| 2| 6×40 mm
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.

If the tumble dryer is being fixed to a concrete plinth on-site, fixing in place is absolutely essential. Fastenings for floating screed must be supplied by the customer on-site.

Options/Accessories

Concrete base (on-site)

The quality of the concrete and its strength must be assessed according to the machine load. The on-site concrete plinth must be fixed adequately to the floor.
