Explanation of the safety notes and warnings on the machine

Installation requirements
The washer-dryer stack may only be commissioned by the Customer Service Department or by a Miele specialist dealer. The washing machine or tumble dryer must not be operated as individual machines.

• The washer-dryer stack must be installed in accordance with applicable regulations and standards. Local energy supplier and water authority regulations must also be observed.
• This washer-dryer stack must only be operated in a room that has sufficient ventilation and is frost-free.

This washer-dryer stack should not be installed or operated in any area where there is a risk of explosion.

Transportation and site access
The machine must not be moved without the transit bars in place. Keep the transit bars in a safe place. They must be refitted if the machine is to be moved again (e.g. when relocating the machine).

General operating conditions
This washer-dryer stack is intended only for use in a commercial environment 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 specialist in instances where increased noise may cause a nuisance.

Installation

Transport the washing machine and the dryer in the washer-dryer stack to the installation site one at a time using a suitable pallet truck, and remove the transport packaging. The washer-dryer stack must be installed by the Miele Customer Service Department or by an authorised dealer. Please observe the information on the installation plan. This washer-dryer stack is only intended for items of laundry that have not been proofed with dangerous or inflammable substances.

During transportation of the machines, ensure their stability.
Do not pick them up by the drum door.

The washer-dryer stack must be set up on a completely level, horizontal and firm surface with the minimum stated floor load 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 washer-dryer stack is the load exerted by the area of the machine in contact with and transferred to the installation surface.
The washer-dryer stack requires a gap of at least 300 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 machine and the rear wall. The washer-dryer stack must not be installed on a carpeted floor. The feet of the washer-dryer stack must be secured to the fastening points on the floor using the fittings supplied. The fittings included are for bolting the washer-dryer stack to a concrete floor. If other floor types are present at the installation site, the fastening material must be ordered by the customer.

Levelling the machine

• Align the washing machine vertically and horizontally using the adjustable feet and a spirit level.

The washing machine must stand evenly and horizontally on all four feet to ensure trouble-free and energy-efficient operation. Otherwise the water and energy consumption increases and the washing machine might move around.

• After aligning the machine, tighten the lock nuts by turning them in a counterclockwise direction with a spanner. This will prevent the feet from adjusting themselves.

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 washer-dryer stack 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, power rating and fuse rating can be found on the data plate on the washer-dryer stack. Before connecting the washer-dryer stack 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 to the washer-dryer stack. If more than one voltage is quoted on the data plate, the washer-dryer stack can be converted for connection to the voltages stated by the Miele Customer Service Department.

• Conversion to a different voltage must only be carried out by the Miele Customer Service Department or by an authorised dealer. The wiring instructions given on the wiring diagram must be followed.

Depending on the models, the machines are delivered with a mains connection cable with/without a plug. References to cable cross-sections in the technical data refer only to the required mains connection cable. Please consult relevant local and national regulations when calculating any other wire gauges.
Tip: It is recommended to connect the washer-dryer stack to the power supply via a plug and socket so that it is easier to conduct electrical safety checks (e.g. during maintenance).
It is advisable to connect the product via a suitably rated plug and socket in accordance with IEC-60309, otherwise for a hardwired connection an all pole means of isolation must be installed at the 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). The wall socket or isolator must remain accessible at all times once the machines have been installed. However, it is always recommended to make electrical connections via a suitable plug and socket so that electrical safety checks, e.g. during repair or maintenance work, can be carried out easily. 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.

• If local and national installation specifications require equipotential bonding, good galvanic contact must be guaranteed. Equipotential bonding must have an earth current rating > 10 mA.

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 position of the seal and screw thread if appropriate.

Cold water connection
For the cold water connection one stopcock each with a ¾” screw thread is required. If a water connection is not available, only a qualified installer may connect the washing machine to the mains water supply. The water inlet hose for cold water is not suitable for connection to a hot water supply. In the event that hot water is not available on site, a cold water supply must be used for the hot water connection. The required amount of hot water should be added to the cold water volume. Alternatively, the hot water connection should be blocked using the blind stopper supplied with the machine and the machine controls should be set to cold water intake by the service technician.

Hot water connection
The same connection requirements as for cold water also apply to hot water up to 70 °C. A suitable connection hose with a threaded union is supplied with the machine. The machine with hot water connection also requires a cold water connection.

Drain pump (depending on model)

In machines with drain pump, the suds are drained through a drain pump with a delivery head of max. 1 m. The drain hose must be installed free of kinks for the suds to drain freely.

There are the following options for draining the machine:

• Drain hose connected to a plastic drain pipe with a rubber sleeve (there is no need to use a siphon)
• Drain hose connected securely to a sink with a plastic nipple
• Connected securely to a floor drain (gully)

If required, the hose can be extended to a length of up to 5 m. The corresponding accessories are available from the Miele Customer Service Department or your Miele dealer. For a drain height of more than 1 m, a replacement drain pump for a delivery head of max. 1.8 m is available from the Miele Customer Service Department or from your Miele dealer.

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 programme 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 additional heating. The permissible wash temperatures are determined by the inlet temperature.

Dispenser connection
The machine is equipped with an interface for external dispenser systems. Adapters for pre-mixed suds or liquid detergent from external dispenser systems for up to 6 connections should be obtained from the Miele Customer Service Department and connected. A separate Connector Box is required for controlling the dispensing pumps electrically. This must be installed by your Miele dealer or the Miele Customer Service Department. It is particularly important to follow the manufacturer’s instructions when using a combination of cleaning agents and special application products.

Supply air and exhaust air management

Ventilation
The air required for drying is taken from the room where the tumble dryer is installed. Ensure sufficient room ventilation, e.g. by means of ventilation openings that cannot be closed in the exterior wall.

• It must not be possible to seal off ventilation openings.
• The room ventilation is only working properly if no low pressure occurs. Avoid low pressure, e.g. by means of ventilation openings in the exterior wall.
• For each tumble dryer, there must be a cross section of 237 cm2 per ventilation opening.

The tumble dryer draws in air at the back. Therefore, there must be a sufficiently large gap between the back of the machine and the wall. This would otherwise hinder a sufficient flow of air as well as the operational performance of the tumble dryer. Observe the necessary spacing between the machine and the wall. Do not reduce the gap between the bottom of the tumble dryer and the floor (e.g. plinth facings, deep pile carpet).

Exhaust air management
The tumble dryer must only be operated if the humid exhaust air generated during drying is led outside through an installed vent ducting. Exceptions regarding the design of the exhaust air management system must be designed in accordance with the applicable local building regulations. Seek approval from the relevant building inspector.

• While installing the ducting, keep the tumble dryer disconnected from the mains power supply.
• Make sure that the plug connections are fully sealed.
• Only use heat-resistant materials with a temperature resistance of at least 80 °C.
• Condensation will form in the exhaust air management system. A condensate drain must therefore be placed at the lowest point in the system.

The opening of the vent ducting (e.g. a wall pipe) must be arranged in such a way that the humid exhaust air:

• Does not flow back into the room where the tumble dryer is installed.
• Does cause damage or unacceptable disturbance.

The air required for drying is taken from the room where the dryer is installed. You must therefore ensure that the room is sufficiently ventilated. Otherwise, there is a risk of suffocation due to exhaust gases being sucked back from other technical systems or fuel-burning installations, and the drying time will be much longer.

The following should be avoided:

• Long vent ducting
• Too many tight bends or elbows
• This will help to stop a reduced dryer performance and excessive time and energy requirements.

Use:

• For the vent ducting: exhaust hose* or a plastic waste water pipe (e.g. HT piping systems) with a minimum diameter of 100 mm.
• *optional accessories

Calculating the total ducting length

The friction of the vent ducting with its bends and various components provides resistance to the flow of air. This friction resistance is expressed as a relative pipe length. The relative pipe length indicates how much greater the resistance of a bend is, for example, when compared to 1 metre of a straight plastic waste water pipe (table I).  Adding together the relative pipe lengths for all of the components gives the total ducting length. The total ducting length expresses the resistance of the entire exhaust air system. As a larger duct diameter has a lower flow resistance, a longer duct requires a greater duct diameter (table II).

Procedure

1. Measure the length needed for the straight sections of ducting. Multiply this value by the corresponding relative pipe length from table I.
2. Calculate the number of bends and components needed. Use Table I to help you add together their relative pipe lengths.
3. Add together all of the relative pipe lengths calculated above in order to calculate the total ducting length.
4. Refer to Table II for the pipe diameter needed for the total ducting length.

Table I

Components| Relative pipe length
Exhaust air hose (flexible aluminium) / pipe (temperature resistance min. 80 °C)
–  1 m laid straight or 1 m straight pipe
–  45° bend (radius of bend = 0.25 m)
–  90° bend (radius of bend = 0.25 m)| 1.0 m
0.6 m
0.8 m
Non-return flap| 14.3 m

• optional accessories
  Table II

  Maximum permissible total
  ducting length| Required diameter
  20 m
  40 m
  80 m| 100 mm
  125 mm
  150 mm

Sample calculation

• A 1 bend, 90°
  = 1 x 0.8 m relative pipe length = 0.8 m

• B/D 2 bends, 90°
  = 2 x 0.8 m relative pipe length = 1.6 m

• C 0.5 m pipe
  = 0.5 x 1 m relative pipe length = 0.5 m

Result: the total ducting length is less than 20 m (as per Table II). A pipe diameter of 100 mm will therefore suffice.

Exhaust air management with plug-in pipes

You will need

• the connector (supplied).
• pipes and connecting pieces from a suitable retailer.

Only use heat-resistant materials with a temperature resistance of at least 80 °C.

• Install the connector (1) and the pipe (2).
• Wrap heat-resistant metallic tape around plug connections.

Exhaust air management with flexible aluminium hose
You will need

• the adapter (supplied).
• Flexible aluminium exhaust air hose (optional accessory).

• Install the adapter (1) and the flexible aluminium exhaust air hose (2).
• Wrap heat-resistant metallic tape around plug connections.

Shared exhaust air ducts
A shared exhaust air duct is only permitted in exceptional cases. The shared exhaust air duct must be approved by the relevant building inspector.

• A non-return flap must be installed for each tumble dryer.

Otherwise, the tumble dryers may be damaged by a backflow of condensation and their electrical safety could be affected.

If 3–5 tumble dryers are installed on one shared exhaust air duct, the pipe diameter D must be increased.

Number of tumble dryers| Factor for increasing the pipe dia meters from Table II
3| 1.25
4–5| 1.5

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