Miele PDR 922 Commercial 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 accord- ance with all appropriate local and national legislation, regulations and guidelines. Please also observe the regulations set out by your insurance provider and energy supplier, acci-dent 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 conver- ted 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 connec-tion 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 it is necessary to install a residual current device (RCD) in accordance with local regu-lations, a residual current device type B (sensitive to universal current) must be used.
Installation notes
Gas connection
The gas connection must only be carried out by a registered installation
technician in ac-cordance with the applicable national regulations (see
installation instructions). The use of a gas socket is not permitted at the
specified heater rating as the flow rate is too low. The gas heating is
configured at the factory in line with the gas specifications on the sticker
on the rear of the appliance. If the gas family is changed, a conversion kit
must be requested from the Miele Cus-tomer Service Department (please specify
the appliance type, serial number, gas family, gas group, gas connection
pressure and country of installation). Follow the installation in-structions.
This conversion may only be carried out by a registered specialist.
Supply air/exhaust air
The tumble dryer may only be operated when the ducting has been connected
and the room is sufficiently ventilated (see installation instructions).
- 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.

Machine-side connection according to ISO 7-1 ½”
To connect the gas appliance, a corrugated metal hose line made of stainless steel according to DIN 3384 must be used. The shut-off device must be provided on-site. Due to an insufficient flow rate, the use of a gas socket is not permissible with the specified heating output. -

Min. connection length 40 mm
This tumble dryer is a gas-burning machine without a flow-operated safety device with fan downstream of heat exchanger (technical design: B22). Waste gas pipework must be pressure-tight. Waste gas connections should be performed in accordance with national and local regulations and may require approval. As relative humidity inside the vent ducting can be as high as 100%, suitable measures must be taken to prevent a backflow of con-densate into the machine.
Air intake
Standard connection: Air intake from installation site
Unobstructed air intake into room recommended: (corresponding to 3 times the
vent cross-section of machine). 531 cm² A sufficient supply of fresh air
should be ensured to replace the air extracted.
Alternative connection: Ducted air intake (from outside building)
- Connector on machine (int. diameter) 161 mm
- Connection pipe provided on site (ext. diameter) 160 mm
Lid removal exposes live components. For safety reasons, the pipe connected for central air intake should be at least 900 mm long and secured using two screws.
