• This washing machine must be installed in accordance with all relevant regulations and standards. Local energy supplier regulations must also be observed.
• This washing machine must only be operated in a room that has sufficient ventilation and which is frost-free.
  The washing 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 environment and must only be operated indoors.

• Ambient temperature: 32-105°F (0-40°C)
  Relative humidity: non-condensing

• Maximum height above sea level of location site: 6500 ft (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 specialist in instances where increased noise may cause a nuisance.

Installation
This washing machine must be transported to its installation site using a suitable pallet truck. 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 for this machine. 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 installation surface.
• The washing machine requires a gap of at least 2″ (50 mm) on each] side to allow for movement during operation. Please ensure a minimum distance of 15 3/4″ (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 fixtures and fastenings supplied.
• The material provided is intended for use in bolting the machine to a concrete floor. If other floor types are present at the installation site, the fixtures and fastenings must be provided 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.

•  The washing machine must be connected to an electrical supplythat 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, power consumption and specifications for external fusing are quoted on the data plate on the washing machine. Ensure that the supply voltage complies with the voltage quoted on
  the data plate before connecting the washing machine to the power supply.

• 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 authorized Service Dealer. The wiring instructions given on the wiring diagram must be followed.

The washing machine can either be hard-wired or connected via a plug and socket that complies with national codes and regulations. For a hard-wired connection an all-pole isolation device must be installed on site.

For hard-wired machines connection should be made via a suitable switch with all-pole isolation which, when in the off position, ensures a 1/8″ (3 mm) gap between all open contacts. These include circuit breakers, fuses and relays.
If the power supply cannot be permanently disconnected, the isolator switch (including plug and socket) must be safeguarded against being switched on either unintentionally or without authorization.
Tip: We recommend connection to the power supply via a suitable] plug and socket which must be easily accessible for servicing and maintenance work after the machine has been installed.

• If it is necessary to install a residual current device (RCD) in accordance with local regulations, a type B residual current device (sensitive to universal current) must be used.
• An existing type A residual current device (RCD) must be exchanged for a type B RCD.
• Equipotential bonding must be in accordance with all national and local regulations.
• Accessories for equipotential bonding are not supplied and need to be ordered separately.

Water connection
The washing machine must be connected to a water supply system in accordance with local and national safety regulations. It can be connected to the water supply without a non-return valve, if national standards permit.
The flow pressure must amount to a minimum of 100 kPa (14.5 psi) and must not exceed an overpressure of 1,000 kPa (145 psi). If the
flow pressure is higher than 1,000 kPa (145 psi), a pressure reducing valve must be used.
The machine must be connected to the water connection using the] water inlet hoses provided.

• The connection points are subject to water connection pressure.
  Turn on the water supplies slowly and check for leaks. Correct the position of the seal and screw thread if appropriate.

Cold-water connection
For the cold-water connection one shut-off valve each with a] ¾” 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 faucet with a 1″ male thread.
The water inlet hose for cold water (blue stripes) is not intended to be used with a hot-water connection.

• To minimize 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 lines” (single lines to hot water generators) can result in cooling down of the water remaining in the pipes if no in constant use. More electrical energy would be needed in order to heat the suds.
• Use the water inlet hose supplied (red stripes) for the hot water connection.
• The temperature of the hot water inlet must not exceed 158°F (70°C) on machines with electric heating (EL).
• The temperature of the hot water intake must not exceed 194°F (90°C) on machines without heating (EH).
• 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, the hot water] inlet hose must also be connected to the cold water supply. An additional A y-piece is required in this case. Cold water consumption increases accordingly to account for the missing hot water inlet.
• 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 inlet.

Hard water connection

• 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 connected to the cold water connection.
• Drain valve In the case of washing machines with a drain valve, a motorized valveis used to drain the machine. A 2 ¾” angle connector can be used fo  connecting the drain valve directly into the waste water system (without a siphon) or into a floor drain (on-site gully with odor trap).
• Thanks to an improved closing mechanism and a larger cross-section, even the coarsest of soil 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 failure.
• A vented drainage system is vital for unimpeded drainage.
• If several machines are connected to a single drain pipe, this shouldbe sufficiently large to allow all machines to drain simultaneously.
•  If the slope for drainage is extremely steep, the piping must be vented to prevent formation of a vacuum in the machine’s drainagesystem.

Slow or obstructed drainage or a backup of water in the drum as a result of undersized pipework can result in faults occurring during program sequences, which will result in fault messages appearing in the machine display.

• Outflowing suds can be as hot as 203°F (95°C). Danger of injury by burning!
  Avoid direct contact.

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 175°F (80°C) is recommended.
The use of disinfection programs is not possible due to the absence of additional 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 and can also be used for high-pressure dispensing systems with water injection.
These connectors are sealed and need to be drilled open using an 8 mm drill bit before connecting.

• Connections 3 to 12 are for liquid detergent. These connectors are sealed and must be cut to the diameter of the hose with a small saw.
• 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 semi-automatically for washing machines fit-ted with an optional multifunction module. Information regarding set-tings is given in the operating instructions.
• A flowmeter or flow sensors can be connected for precise monitoring of the dispensing quantity.
• 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 parts or accessories from other manufacturers may void the warranty, and Miele cannot accept liability.

Payment system kit (BSK)
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 Miele Technical Service.
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 Technical Service or an authorized Miele dealer only. An external power supply is not required for a payment system.

Peak-load negotiation kit (BSS)
The washing machine can be connected to an energy management system via a peak-load negotiation kit which is available as an optional accessory.
Peak-load negotiation 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 program is stopped and a message appears in the display on the washing machine. The program is resumed automatically when the peak-load system reactivates the heating.

XKM RS232 communication module
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 Professional 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 accordance with EN 60950.
Machines connected to this interface must also be SELV compliant.
Communication module XKM RS 232 is supplied with a connection cable and a D -sub-connector.

Vapor and suds venting kit (APWM 063)
