Installation notes
Installation requirements
The tumble dryer must only be installed and commissioned by Miele Customer Service Department or an authorized dealer.
Electrical connection
The electrical connection must be established by a qualified electrician.
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.
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).
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.
Air intake/exhaust air
The tumble dryer may only be operated when the ducting has been connected properly and the room is sufficiently ventilated.

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)
Connection with male thread | 10×35 mm |
Washers and nuts | M10 |
Accessories for equipotential bonding are not supplied and need to be ordered separately. |
Peak-load negotiation (optional)
Supply voltage for control contacts | AC 230 V |
The minimum cross-section for the connection cable | 5×1.5 mm² |
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. |
