Miele PDR 928-528 EL Commercial Tumble Dryers Installation Guide

Miele PDR 928-528 EL Commercial Tumble Dryers

Product Information

The Commercial Tumble Dryer PDR 928/528 EL is an electrically heated dryer designed for commercial use. It is recommended to read the installation instructions and follow all relevant regulations and standards to prevent accidents and machine damage.

• Installation and commissioning should be done by Miele Service or an authorized dealer to ensure proper installation.
• The tumble dryer should be installed in a well-ventilated, frost-free room.
• Do not install the tumble dryer behind a closeable or sliding door.
• The maximum opening angle of the tumble dryer door should not be limited by objects or doors.
• Miele recommends securing both front screw feet of the tumble dryer to the floor with tensioning strips, especially when installing on a base or on an offshore installation.
• Only use genuine Miele spare parts and accessories to avoid voiding the warranty.
• The tumble dryer should only be operated when the ducting is properly connected and the room is sufficiently ventilated.
• The length and diameter of the supply air or exhaust pipe should be calculated based on the structural conditions on-site, aiming for maximum airflow efficiency.
• Refer to Table 1 for substitute duct lengths and Table 3 for minimum dimensions of ventilation openings depending on the cross-section of the vent duct.

Product Usage Instructions

1. Ensure that the tumble dryer is installed in a well-ventilated, frost-free room.
2. Do not install the tumble dryer behind a closeable or sliding door. Make sure the maximum opening angle of the tumble dryer door is not limited by objects or doors.
3. If installing on a base or on an offshore installation, secure both front screw feet of the tumble dryer to the floor using tensioning strips.
4. Use only genuine Miele spare parts and accessories to avoid voiding the warranty.
5. Connect the ducting properly for supply air and exhaust air. Ensure that the room is sufficiently ventilated before operating the tumble dryer.
6. Calculate the length and diameter of the supply air or exhaust pipe based on the structural conditions on-site. Aim for maximum airflow efficiency by keeping the pipeline as short as possible and minimizing the number of elbows.
7. Refer to Table 1 for substitute duct lengths and Table 3 for minimum dimensions of ventilation openings based on the cross-section of the vent duct.

Installation requirements

• Risk of injury or damage to property due to improper installation. Incorrect installation of the tumble dryer can lead to personal injury or damage to prop-erty.
  It is recommended that installation and commissioning be accomplished by Miele Ser-vice or an authorized dealer.

Observe all local codes.

• The tumble dryer must be installed in accordance with all relevant regulations and stan-dards.
• The dryer must only be operated in a room that has sufficient ventilation and which is frost-free.
• The tumble dryer must not be installed behind a closeable door or a sliding door. The maximum opening angle of the tumble dryer door must not be limited by objects or doors. It must be possible to fully open the tumble dryer door at any time.

Floor anchoring
Miele generally recommends securing both of the tumble dryer’s front screw feet to the floor with tensioning strips.

In the following cases, the tumble dryer must be secured to the floor with tensioning strips

• when installing on a base
• on an offshore installation

Optional accessories
Only use genuine Miele spare parts and accessories with this machine.
Using parts or accessories from other manufacturers may void the warranty, and Miele cannot accept liability.

Communication box

• The optional communication box allows external hardware from Miele and other suppliers to be connected to the Miele Professional machine. External hardware includes e.g., peak-load systems, pressure sensors, or an external vent flap.
• The communication box is supplied with voltage by the Miele Professional machine.
• The separately available set consists of the communication box and fasteners for installa-tion on the machine or on the wall.

XKM 3200 WL PLT

• The optional Miele communication module can be used to establish a data connection be-tween a Miele Professional machine and a data processor in accordance with the Ethernet or WiFi standard.
• This communication module fits into the communication slot which is a standard feature on all machines. The communication module offers the option of intelligent app-based communication with external systems. In addition, it can display detailed machine and pro-gram status information.

Installation notes
This module forms the basis for wired communication with Miele MOVE.

It is not possible to integrate the machine into the “Miele@home” app for domestic installations.
The communication module is intended exclusively for commercial use and is supplied with voltage directly via the Miele Professional machine. No additional power connection is required. The Ethernet interface provided via the communication module complies with SELV (safety extra low voltage) requirements in accordance with EN 60950. Connected external machines must also comply with SELV.

• Supply air, exhaust, and ventilation cross-sections
• Supply air/exhaust air

The tumble dryer may only be operated when the ducting has been connected properly and the room is sufficiently ventilated.

Calculating the total length and diameter of a supply-air or exhaust pipe
The length of the required ductwork and the number and shape of the elbows are deter-mined by the structural conditions on-site. In order to maximize the airflow efficiency, the pipeline should be as short as possible and contain few or minimal elbows.

• The exhaust ducting must not be made from flammable materials. Otherwise there is a risk of fire.
• Use only non-flammable materials for the exhaust ducting. All local regulations for metallic ducting must be observed. Plastic must not be used for ventilation.
• In upward exhaust ducting systems, a condensate drain must be fitted to the bottom. The condensate must be drained via a water collection tray or a floor drain positioned in an ap-propriate location.
• If air is being directed from multiple appliances into a combined line (exceptional circum-stances), a non-return device (non-return flap) must be installed in each separate line to prevent backflow.
• To make subsequent cleaning of the pipes easier, cleaning flaps should be fitted to elbows wherever possible.
• The on-site exhaust ducting and venting to the outdoors must be regularly checked for lint deposits and cleaned if necessary.

Configuring the room ventilation opening

• Rooms in which rotary irons and tumble dryers are operated must have an induced ventilation system (e.g., ventilation slots in windows and doors, wall openings with grilles, or opened windows or skylights).

For example 1
A duct diameter of 6″ (150 mm) was specified in example 1. According to this duct diame-ter, a room ventilation opening with a size of 17′ 5″ (531 cm) is required. The edge length is 9 1/16″ (230 mm) (see Table 3).

For example 2
A total duct diameter of 8 11/16″ (220 mm) was specified. According to this duct diameter, a room ventilation opening with a size of 37′ 4″ (1,140 cm) is required. The edge length is 14 13/16″ (377 mm) (see Table 3).

For example 3
Since in this case the tumble dryer is connected to a central air supply, additional ventilation openings are not needed.

Exhaust air

Supply air
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).
• 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) 6 5/16″ (161 mm)
