Product Usage Instructions

Safety Precautions

Before using the commercial washing machine, ensure you have read and understood all safety notes and warnings provided in the user manual. Pay particular attention to warnings regarding hot surfaces and high voltage levels up to 1000 volts. Proper earthing and equipotential bonding are essential for safe operation.

Water Connection

For optimal energy efficiency, consider connecting the washing machine to a hot water ring circuit. Use the supplied red-striped inlet hose for hot water connection. In cases where hot water is unavailable, connect the hot water inlet hose to the cold water supply using a Y-piece to maintain functionality, although this will increase cold water consumption.

Drainage System

Ensure proper drainage to prevent faults during programs. Undersized pipework can lead to slow drainage or water backup in the drum, triggering fault messages. Address any drainage issues promptly to maintain machine performance.

Dispenser Pump Connections

The washing machine supports up to 12 dispenser pumps for various detergents and additives. Connect viscous agents and high-pressure dispensing systems to designated connectors at the back of the machine. Ensure compliance with safety standards EN 61770 and EN 1717 for dispenser pump installations.

FAQ

Q: Can I use spare parts from other manufacturers with this machine?

A: No, it is recommended to only use genuine Miele spare parts and accessories with the commercial washing machine. The use of non-Miele parts may void the warranty and could pose risks to the machine’s performance.

Installation notes

Explanation of the safety notes and warnings on the machine

Installation requirements

The washing machine must be installed and commissioned by a Miele Service technician or by an authorised dealer.

• The washing machine must be installed in accordance with applicable regulations and standards. Local energy supplier and water authority regulations must also be observed.
• This washing machine must only be operated in a room that has sufficient ventilation and which is frost-free.
  This machine should not be installed or operated in any area where there is a risk of explosion!

General operating conditions

This washing machine is intended only for use in a commercial envir-onment and must only be operated indoors.

• Ambient temperature: 0-40 °C
• Relative humidity: non-condensing
• Maximum height above sea level of location site: 2000 m

Depending on the nature of the installation site, sound emissions and vibration may occur.

Tip: Have the installation site inspected and seek the advice of a pro- fessional in instances where increased noise may cause a nuisance.

Installation

Transport the washing machine to its installation site using a suitable pallet truck and remove the transport packaging.

• The washing machine must be set up on a completely level, horizontal and firm surface with the minimum stated load bearing capacity (see “Technical data”).
  Tip: A concrete floor is the most suitable installation surface. It is far less prone to vibration during the spin cycle than wooden floorboards or a carpeted surface.

• The floor load created by the washing machine is the load exerted by the area of the machine in contact with and transferred to the install-ation surface.

• The washing machine requires a gap of at least 50 mm on each side to allow for movement during operation. Please ensure a minimum distance of 400 mm is maintained between the rear of the appliance and the rear wall.

• The washing machine must not be installed on a carpeted floor.

• The feet of the washing machine must be secured to the fastening points on the floor using the fittings supplied.

• The fittings supplied are for bolting the machine to a concrete floor. If other floor types are present at the installation site, the fastening ma-terial must be ordered by the customer.

Electrical connection

The electrical connection must only be carried out by a qualified electrician who must ensure that all electrical work is carried out in accordance with applicable electrical regulations and standards (BS 7671 in the UK).

• This washing machine must be connected to an electrical mains supply that complies with local and national regulations. Please also observe your insurance and energy supplier’s regulations as well as any health and safety at work regulations.
• The required voltage, connected load and fusing rating can be found on the data plate on the washing machine. Before connecting the ma-chine to the power supply, please ensure that the mains supply voltage complies with the values given on the data plate.
• Connection to a supply voltage other than the one quoted on the data plate can lead to functional faults and damage the washing machine!
• If more than one voltage is quoted on the data plate, the washing machine can be converted for connection to the voltages stated.
• Conversion to a different voltage must only be carried out by a Miele Service engineer or by an authorised Service Partner. The wiring instructions given on the wiring diagram must be followed.
• Tip: We recommend connection to the power supply via a suitably rated plug and socket which must be easily accessible for servicing and maintenance work after the machine has been installed. An elec-trical safety test must be carried out after installation and after any service work.
• The machine should be connected with a suitably rated plug and socket in accordance with IEC 60309-1 or hard wired. For a hard wired connection an all-pole isolation device must be installed.
• For hard-wired machines connection should be made via a suitable mains switch with all-pole isolation which, when in the off position, ensures a 3 mm gap between all open contacts. These include circuit breakers, fuses and relays (IEC/EN 60947).
• If the mains supply cannot be permanently disconnected, the isolator switch (including plug and socket) must be safeguarded against being switched on either unintentionally or without authorisation.
• 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.
• An existing type A residual current device (RCD) must be exchanged for a type B RCD.
• An equipotential bond with good contact connection must always be provided in accordance with all national and local regulations.
• Accessories for equipotential bonding are not supplied and need to be ordered separately.

Water connection

For compliance to Regulation 4 of the water regulations guide please fit the supplied double check valves to the on-site water supplies for each inlet hose used. The non-return valve prevents water from the water inlet hose from flowing back into the on-site drinking water supply.

• Non-return valves are supplied.
• The flow pressure must amount to a minimum of 100 kPa and must not exceed 1000 kPa. If the flow pressure is higher than 1000 kPa, a pressure reducing valve must be used.
• The machine must be connected to the water supply using the inlet hoses provided.
• The connection points are subject to water supply pressure.
• Turn on the stopcock slowly and check for leaks. Correct the posi-tion of the seal and screw thread if appropriate.
• Only connect the washing machine to the water supply with the hoses supplied.

Cold water con-nection
For the cold water connection one stopcock each with a 3/4″ external thread is required. A connector (Y-piece) can be used if required to connect 2 water inlet hoses with a ¾” screw thread to a single stopcock with a 1″ male thread.

Hot water connection

• To minimise energy consumption during operation with hot water, the washing machine should be connected to a suitable hot water ring circuit if present.
• So-called “transmission pipes” (single pipes to hot water generators) can result in cooling down of the water remaining in the pipes if not in constant use. More energy would then be consumed to heat the suds up again.
• Use the inlet hose supplied (red stripes) for the hot water connection.
• The temperature of the water intake must not exceed 60 °C on ma-chines with electric heating (EL).
• The temperature of the water intake must not exceed 90 °C on ma-chines with reduced heater rating (RH).
• The machine must be connected to the water supply using the inlet hoses provided.
• If there is no hot water supply at the installation location for the wash-ing machine, the inlet hose for hot water must also be connected to the cold water supply. A Y-piece is required in this case. The cold wa-ter consumption increases accordingly to account for the missing hot water intake.
• For functional and technical reasons it is not possible to operate the machine exclusively with a hot water connection.
• Even if a hot water connection is present, the washing machine must be connected to a cold water intake.

Hard water connection

Connection for hard water. For the hard water connection, the same requirements apply as for the cold water connection.

If there is no hard water connection on site, the hose must be connec-ted to the cold water connection.

Drain valve

• In the case of washing machines with a drain valve, a motorised valve is used to drain the machine. An HT DN 70 angle connector can be used for draining the machine directly into the waste water system (without a siphon) or into an on-site floor drain (with odour trap).
• Thanks to an improved closing mechanism and a larger cross-sec-tion, even the coarsest of soiling does not leave any deposits or debris behind which could result in blockages. The drain valve can also be operated manually to allow the suds container to be emptied in the event of a power outage.
• A vented drainage system is vital for unimpeded drainage.
• If several machines are connected to a single drain pipe, this should be sufficiently large to allow all machines to drain simultaneously.
• The appropriate Miele installation kit (mat. no.: 05 238 090) is available to order from the Miele Customer Service Department or your Miele dealer for venting an HT DN 70 pipe.
• If the slope for drainage is extremely steep, the piping must be ven-ted to prevent formation of a vacuum in the machine’s drainage sys-tem.
• Slow or obstructed drainage or a backup of water in the drum as a res-ult of undersized pipework can result in faults occurring during pro-grammes, which will result in fault messages appearing in the display.
• Outflowing suds can be as hot as 95 °C. Danger of burning!Avoid direct contact.

Water connection for variants with reduced heater rating (RH)
The appliance should be connected to cold and hot water supplies. A minimum hot water temperature of 80 °C is recommended in order to use all programmes. Lower temperatures may result in longer pro-gramme running times or cause programmes to be interrupted. Water inlet temperatures below 60 °C are not permitted, as they can lead to significantly longer programme running times.

Water connection for variants with external heating (EH)
The appliance should be connected to cold and hot water supplies. A minimum hot water temperature of 80 °C is recommended. The use of disinfection programmes is not possible due to the absence of ad-ditional heating. The permissible wash temperatures are determined by the inlet temperature.

Dispenser pump connections
Up to 12 dispenser pumps can be connected to the washing machine.\

Dispenser pump connections on the back of the machine
Connections 1 and 2 are provided for viscous agents can also be used for high pressure dispensing systems with water injection. The dis-pensing systems must be fitted with a separate drinking water safety mechanism in accordance with EN 61770 and EN 1717. The maximum flow rate is 1500 ml/min with a maximum flow pressure of 300 kPa.

These connectors are sealed and need to be drilled open using a 8 mm drill bit before connecting.

• Connections 3 to 12 are provided for liquid detergent. High pressure dispensing systems with water injection must not be connected to these connections. The connectors are sealed and must be cut to the diameter of the hose with a small saw before they are connected.
• If opened connectors are no longer required, they must be resealed using a suitable sealant (e.g. silicone).
• Connection terminals for five time-controlled dispenser pumps, which can be operated without a multifunction module, are located behind the cover adjacent to the electrical connection.
• Calibration of the dispenser pumps and regulation of dispensing quantities is carried out partly automatically for washing machines fitted with an optional multifunction module. Information regarding settings is given in the operating instructions.
• A flowmeter or flow sensors can also be connected for monitoring the dispensing quantity precisely.
• Connections for level monitoring are available for every agent dis-pensed.

Optional accessories
Only use genuine Miele spare parts and accessories with this ma-chine.
Using spare parts or accessories from other manufacturers will in-validate the warranty, and Miele cannot accept liability.

BSK = Payment system kit
The washing machine can be equipped with a payment system (e.g. for self- service operations) using the optional BSK payment system kit. This must be connected and programmed by a Miele Service tech-nician. Payment systems with mechanical or electronic coin validator are available from Miele as optional accessories for individual target groups.
The programming required for connecting a payment system must be carried out by Miele Service or an authorised Miele dealer only. A separate electrical connection is not required for a payment system.

BSS peak-load ne-gotiation kit

• The washing machine can be connected to a peak-load shut-off or an energy management system using a BSS peak-load negotiation kit which is available as an optional accessory.
• The peak-load cut-out monitors the energy consumption of a system and deactivates individual pieces of equipment temporarily in order to ensure that certain total load limits are not exceeded. Monitoring is externally controlled.

The kit provides three signal contacts and a neutral conductor via a terminal block. The terminal block is marked with “a”, “b”, “c”, and “d”.

1. Output signal, start of machine operation
2. Output signal, machine heating request
3. Peak-load input signal, machine heating deactivated
4. Neutral conductor

When the peak-load function is activated the current programme is stopped and a message appears in the display on the washing ma-chine. At the end of the peak-load function the programme resumes automatically.

XKM RS232 com-munication mod-ule
The serial interface RS-232 can be retrofitted to the washing machine via an XKM RS 232 (optional accessory available from Miele). This communication module must only be used with Miele Profes-
sional machines that are fitted with an appropriate slot for the module.
The data interface provided via communication module
XKM RS232 complies with SELV (Safety Extra Low Voltage) in ac-cordance with EN 60950.
Communication module XKM RS 232 is supplied with a connection cable and a D -sub-connector.

Vapour and foam venting kit (APWM 063)
