Miele PDR 528 G Plan Commercial Tumble Dryer

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 property. It is recommended that installation and commissioning be accomplished by Miele Service or an authorized dealer.

In Massachusetts, installation must be performed by a licensed installer/gas fitter.

  • The tumble dryer must be installed in accordance with all relevant regulations and standards. Observe all local codes.
  • 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 closed 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
Secure the two screw feet at the front of the tumble dryer to the floor with the tensioning straps supplied.

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 installation on the machine or on the wall.

XKM 3200 WL PLT
The optional Miele communication module can be used to establish a data connection between a Miele Professional machine and a data processor per 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 program status information. 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 under 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 determined by the structural conditions on-site. 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 appropriate location. If air is being directed from multiple appliances into a combined line (exceptional circumstances), 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.

When connected to the vent ducting through the exhaust duct of a machine, particular care must be taken to make sure the connection is secure and air- tight. With complex ducting with many bends and additional components, or when several different machines are connected to a shared duct, it is recommended that a detailed pipework calculation is carried out by a qualified specialist.

The vent ducting must not be channelled into a chimney or flue already in use for any gas-, coal-, or oil-burning installation. The warm and moist exhaust air is to be conducted outside or to a suitable venting duct over the shortest path possible. The vent ducting must be laid so that airflow is not hindered. To achieve this, use as few bends as possible along with short pipelines and well-made connections and transitions checked for air-tightness. No filters or grilles may be fitted in the vent ducting. The end of the vent ducting leading out into the open should be protected against the elements, e.g., with a downward-facing 90° bend.

  • During tumble dryer operation, the room must be adequately ventilated.

Room ventilation opening for air intake from the setup room
The minimum dimension of the ventilation opening depends on the cross-section of the vent duct.Miele-PDR-528-G-Plan-Commercial-Tumble-Dryer-

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 diameter, 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.

Gas

Take these safety precautions if you smell gas

  • Extinguish all flames immediately.
  • Close the on-site gas shut-off device, the gas shut-off device on the gas meter or the main gas shut-off device immediately.
  • Open all windows and doors immediately.
  • Do not light any naked flames (e.g., matches or lighters).
  • Do not smoke.
  • If there is the smell of gas in a room, never enter the room with an open flame.
  • Do not carry out any actions that will create electrical sparks (such as pulling out electri-cal plugs or pressing electrical switches or bells).
  • If you cannot find the cause of the gas smell and all gas valves have been shut off, please call the gas supply company immediately.

If other persons are being shown how to operate the machine, they must be given and/or made aware of these important safety precautions. During installation, the technical regulations for gas installations as well as national and regional building regulations, fire regulations, and specifications from the relevant gas supply companies must be adhered to.When planning a gas-heated system, contact the relevant gas supply company and a building regulations inspector.

What needs to be observed before commissioning

Please specify the gas type, gas group, and connection pressure.

Installation site

  • Gas-heated tumble dryers must not be operated in a room where cleaning machines operate with solvents containing perchloroethylene or CFCs. During combustion, any vapors that are emitted will break down into hydrochloric acid, leading to consequential damage affecting the laundry and the machine. Air exchange must not take place if machines are set up in separate rooms.
  • Rooms with fuel-burning installations must be adequately aerated and ventilated. Any gas-heated machine must be considered to be a fuel-burning installation (regardless of its gas flow rate).
  • If liquid gas-heated machines are being set up below ground level, the operator must provide the system with the necessary aeration and induced ventilation equipment under technical regulations for liquid propane.
  • If no low pressure occurs when a full fire is burning in all fuel-burning installations, this means that the room ventilation is working properly, even if the exhaust gases from the installations are being extracted mechanically. This ensures that the gas is being combusted correctly and that the exhaust gases are being evacuated completely.
  • It must not be possible to seal off aeration and ventilation openings.
    • Before completing commissioning, maintenance, conversion, and repair work, all gasconducting components – from the manual shut-off valve to the burner jet – must be checked for leaks. Particular attention must be paid to the measuring stubs on the gas valve. Checks must be performed when the burner is both switched on and switched off.
    • Installing thermal shut-off equipment on site is recommended.
    • If gas-heated appliances are accessible to anyone, it is also necessary to check whether a gas flow monitor needs to be used.

Exhaust gas evacuation ducts
Gas-heated Miele Tumble Dryers are type B22 gas fuel-burning installations without flow-safeguarding equipment and with a fan behind the heater.

  • The mixtures of exhaust gas and air that are emitted by gas-heated tumble dryers must be evacuated through a suitable chimney and out into the atmosphere via the roof.
  • Exhaust air evacuation ducts and exhaust gas evacuation ducts must be kept as short as possible. The evacuation ducts must rise vertically up to the flue.
  • Only materials that are resistant to heat and sooting may be used.
  • A condensate drain must be placed at the lowest point of the exhaust ducting. The condensate must be drained via a water collection tray or a floor drain positioned in an appropriate location. No filters or grilles may be fitted in the pipeline. The exhaust air or exhaust gas ducting must be installed leak-tight.

Compliance with the latest guidelines for approving exhaust gas systems containing low-temperature exhaust gases must be assured.

Exceptions

  1. Where it is not possible for evacuation to take place through a single duct, appropriate measures must be taken to ensure that the exhaust gas/air mixture from the machine is not able to enter the room in which the machine is located via the exhaust duct for other machines (e.g., through the use of baffles and merged lines that do not hinder the flow). When selecting and installing equipment that will not hinder the flow, it is important to ensure that high pressure cannot arise at the side that is not being oper-ated. Machines fitted with fans must not be connected to the same vent flue as those without fans.
  2. When evacuating the exhaust gas/air mixture through the exterior wall, no dangers or unreasonable nuisance may arise.
  3. With a combined line, the exhaust air ducts for the individual machines must be installed horizontally in the combined line in a way that does not hinder the flow. The cross-section of the vent flue must not be smaller than the cross-section of the combined line. Combined lines must be kept as short as possible and must rise vertically up to the vent flue. A condensate drain is required at the lowest point.

All exceptional cases, and particularly those where a combined line is being installed, require special permission from the relevant building regulations inspector supervisor’s office. Diameter and cross-section of the exhaust ducting

What needs to be observed during commissioning

Check that the points listed in section 1 (“What needs to be observed before commission-ing”) have been taken into consideration. The following should be carried out in the given order when commissioning or converting the appliance:

  1. Ask the gas supply company what the gas type, gas group, and connection pressure are, and compare this information with the data specified on the tumble dryer (see the sticker at the rear).
  2. Check the factory-set jet pressure based on the tables “Settings with natural gas”/”Settings with liquid propane” and correct it if necessary.
  3. If the gas type, gas group, or connection pressure is different, it must be converted as instructed in the section entitled “Connection and conversion instructions” and the sticker at the rear of the tumble dryer must be replaced accordingly.
  4. If the gas type needs to be changed, please request the appropriate conversion kit from Miele Service. When doing so, please specify the product name and the appli-ance number, as well as the gas type, gas group, gas connection pressure, and country where the appliance has been set up.
  5. Set the jet pressure at the tumble dryer’s gas regulating valve (see tables “Settings with natural gas”/”Settings with liquid propane”).
  6. Switch on all gas consumers that are present (including the installed tumble dryer).
  7. Measure the connection pressure. The connection pressure must be within the ranges specified in local guidelines.

Connection and conversion instructions

  • Connection and conversion work must be performed by Miele Service or by an authorized dealer.
  • The settings for tumble dryers are made at the factory in line with the gas specifications at the rear of the appliance.

Gas hose

The gas appliance must be connected using a corrugated metal hose assembly made from stainless steel under DIN 3384. Alternatively, a hose that complies with DIN EN 16617 may be used with connections per DIN 3384. The maximum length of the hose is 6′ 6″ (2 m). When selecting a hose, the required flow rate and applicable national regulations must also be taken into account.

Jet pressure adjustment
Make sure that the maximum pressure is set first. Else the minimum pressure would be changed by turning the nut.

  • Loosen the locking bolts of the connection pressure and jet pressure measuring stub.
  • Check the connection pressure and jet pressure.
  • Remove the cap from the pressure regulator.
  • Fit a socket wrench or a ring spanner to the nut of the pressure regulator.

Setting maximum pressure at full heating
Values for natural gas: see table “Settings with natural gas”; for values for liquid gas: see table “Settings with liquid propane”

  • To increase or reduce the maximum jet pressure turn the nut in a clockwise or counterclockwise direction. Adjusting the minimum pressure with power supply interrupted
  • Pull out the plug. You need a slotted Screwdriver to adjust the minimum pressure.
  • To increase or reduce the minimum jet pressure turn the slotted screw inside the nut in a clockwise or counterclockwise direction. Make sure that the nut does not turn with it.
  • Insert the plug again.
  • Fit the cap onto the pressure regulator.
  • Seal the connection pressure and jet pressure measuring stubs with the locking bolts.

PDR x14/x18/x22 = 1 jet; PDR x28/x44 = 2 jetsqMiele-PDR-528-G-Plan-
Commercial-Tumble-Dryer-fig-9

Burner Conversion

  • Replace the jet and the sealing ring (included with the conversion kit).
    • Natural gas = large hole
    • Liquid propane = small hole

Additional steps necessary to convert to liquid gas are outlined in the “Conversion kit for natural gas to liquid gas conversion”.Gas lines and screw connections may leak after connection and conversion work. Gas may escape. After connection and conversion work, the gas lines, all screw connections (including those on the jets), and the locking bolts on the measuring stubs must be checked to ensure they are leak-tight. This check must be performed both while the appliance is at a standstill and while it is in operation.
