Miele PDR 928/528 SI Steam Heated Stainless Steel Professional Vented Dryer

Installation requirements

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.

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.
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 which 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 authorisation.
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.

Steam connection

The steam connection must only be carried out by a registered installation technician. The information from the data plate, the wiring diagram and the documentation accompanying the appliance must be noted and complied with when connecting steam-heated Miele appliances.

Condensate connection

The condensate separator must be installed so that when the system is not operating, the heater bank is completely emptied. This means that no condensate may remain in the heater bank. The installation of an inverted bucket condensate trap is recommended.

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

Standard connection

Steam connection

Steam overpressure	600–1000 kPa
Boiling point	165–184 °C
Mass flow, peak capacity	60 kg/h
On-site threaded union for steam (internal thread)	½” mm
Length of steam valve connection cable	500 mm

Steam valve, dirt filter and steam shut-off valve must be fitted by the customer on site.
The steam valve must be fitted in the direct vicinity of the steam connection.

Condensate connection

On-site threaded union (internal thread)	½” mm

Shut-off equipment and condensate trap must be fitted by the customer on site.

Exhaust air

Maximum nominal volume flow rate in extraction mode (PDR 9xx only)	1000 m³/h
Maximum nominal volume flow rate (PDR 5xx only)	1100 m³/h
Maximum permitted pressure loss	510 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 installation site
Recommended free air intake cross-section into the room:
(equivalent to 3 times the exhaust air cross-section of a machine). 531 cm²
There must be sufficient air intake to the installation site to match the air outlet volume.

Alternative connection: air intake connection directly from outdoors

Connection sleeve on machine side (internal diameter)| 161 mm
Connection pipe provided on site (external diameter)| 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.
