Miele PDR 918 Gas Heated Commercial Dryer

Miele-PDR-918-Gas-Heated-Commercial-Dryer-product

To avoid the risk of accidents or damage to the machine, it is essential to read these instructions before it is installed and used for the first time.

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 theMiele 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 it is necessary to install a residual current device (RCD) in accordance with local regulations, 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 accordance 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 Customer Service Department (please specify the appliance type, serial number, gas family, gas group, gas connection pressure and country of installation). Follow the installation instructions. 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.

Technical data

Voltage variants/electrical data

Standard connection
Voltage 1N AC 230 V
Frequency 50 Hz
Total connected load 0.6 kW
Fuse rating (on-site) 10 A
Connection cable, min. cross-section 3×1.5 mm²
Cable gland M20

Gas connection

Nominal heat rating 18 kW
Machine-side connection according to ISO 7-1
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. ½”
Connection thread for natural gas, on-site (internal thread) ½”
Connection thread for liquid gas, on-site (internal thread) ½”
Alternative on-site connection with high-precision steel pipe according to DIN 2391/DIN2393, with smooth pipe end DN 12
Min. connection length 40 mm

Connection pressure according to DIN EN 437. Connection to gas supply must comply with national regulations

Waste air/gas

Max. nominal air flow in vented mode (PDR 9xx only) 680 m³/h
Max. nominal air flow (PDR 5xx only) 680 m³/h
Max. permissible pressure loss 290 Pa
Connection on machine side (ext. diameter) 150 mm
Connection pipe provided on site (int. diameter) 150 mm
Max. temperature 80 °C

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 condensate 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
