Installation and planning notes

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 applic-

able 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!

Storage / Transport

The following conditions must be observed for transport and storage:

– Ambient temperature: 0 - 40 °C

– Humidity: non-condensing

General operating conditions

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

– Ambient temperature of location: 0 - 40 °C

– Relative humidity: non-condensing

– Maximum height above sea level of location site: 2000 m

Installation and planning notes

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 level and firm surface with
the minimum stated load bearing capacity (see "Technical data").

The floor load created by the washing machine is concentrated and
transferred to the installation footprint via the machine feet.

Tip: A concrete floor is the most suitable installation surface, being
far less prone to vibration during the spin cycle than wooden floor­boards or a carpeted surface.

The washing machine requires a gap of at least 50mm at each side
to allow for movement during operation. To ensure suitable access for
further maintenance and service work, please ensure a minimum dis­tance of 400mm is maintained between the back of the machine and
the wall.

Installation on concrete plinth

The washing machine can be installed on a concrete plinth if desired.

The concrete materials and the durability of the concrete plinth must
be assessed in accordance with the floor load bearing capacity
given in "Technical data".

 To guarantee the stability of the washing machine, make sure that

the concrete plinth is sufficiently stable on the floor and that it is
capable of withstanding any burden or force from the washing ma­chine.

 The washing machine must be secured to the concrete plinth using

the fixtures and fastenings supplied.

 The washing machine must be secured to the plinth immedi­ately after installation!

There is a risk of the washing machine falling off a raised plinth dur­ing a spin cycle if it is not secured.

PW 811 / PW 814 / PW 818 5

Installation and planning notes

Levelling the machine

 Align the washing machine vertically and horizontally using the ad-

justable 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

an counterclockwise direction with a wrench. This will prevent the
feet from adjusting themselves.

Securing the machine

 The feet of the washing machine must be secured to the concrete

plinth using the fixtures and fastenings supplied.

Fittings supplied are for installation on a concrete floor. For other
types of flooring, please purchase suitable fastening materials sep­arately.

Installation and planning notes

Installation of steam-heated washing machines

 The steam connection must only be carried out by a registered
installation technician. During connection please observe the in­stallation instructions, the data plate on the washing machine, the
wiring diagram, the installation diagram and the documentation
supplied.

Steam-heated washing machines must in all cases be secured to
the floor!

Steam connection valve

Condensate trap

Before connecting a steam-heated machine, ensure that the steam
inlet valve, the dirt filter and the steam shut-off valve have been cor­rectly installed on site.

Steam valves are available from Miele specialist dealers or Miele
Spares Dept.

For steam-heated washing machines, a condensate trap for the con­densate is required at the installation site. The condensate trap en­sures that condensate is completely drained away from the washing
machine heater bank.

The condensate trap must be installed in such a way that condens­ate cannot get back into the heater bank when the machine is not
in operation.

Tip: Use a bell condensate trap for the condensate drain.

Installation and planning notes

Heater bank in­formation

Fitting informa­tion for steam and
condensate hoses

To avoid damage to the heater bank, the following must be observed
during commissioning:

– In order to avoid unnecessary heat variations, ensure that heating is

even. Do not allow sudden bursts of steam.

– To prevent corrosion, treatment of the water supply is absolutely

essential. In particular, when the machine is not in operation, it
must be ensured that no air or CO2 can enter the system.

– Protect the heater bank from aggressive gases

– The entire heating system must guarantee that no operating pres-

sure or temperature can arise that is higher than the details given
on the data plate.

– All appropriate regulations, standards and legislation from respons-

ible authorities and accident prevention associations for heating
and ventilation systems (in particular for the operation of the heat
exchanger) must be observed.

Make sure that steam and condensate hoses are not twisted or com­pressed. Do not use the hoses to compensate for connection tube
misalignments!

Installation and planning notes

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 machine 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 Dealer. 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 elec­trical safety test must be carried out after installation and after any
service work.

The machine can either be hard-wired or connected using a plug­and-socket connection in accordance with IEC 60309-1. For a hard­wired connection an all-pole isolation device must be installed on
site.

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.

Installation and planning notes

 If it is necessary to install a residual current device (RCD) in ac-

cordance 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 necessary, equipotential bonding with good galvanic contact

must be guaranteed in compliance with all applicable local and na­tional installation specifications.

Equipotential bonding must have an earth current rating >10mA
Accessories for equipotential bonding are not supplied and need to
be ordered separately.

12 PW 811 / PW 814 / PW 818

Installation and planning notes

Plumbing

The washing machine complies with current local and national
safety regulations. In the UK it must be connected to the drinking
water supply using the non-return valve supplied.

The water flow pressure must be at least 1bar and should not exceed
10bar. If it exceeds 10bar a pressure reducing valve must be used.

The machine must be connected to the water supply using the inlet
hoses provided. Extension hoses are available from Miele as spare
parts.

 The connection points are subject to water supply pressure.
Turn on the tap slowly and check for leaks.
Correct the position of the washer and union if appropriate.

Cold water con­nection

Use the inlet hose supplied (cold - blue stripes) for the cold water
connection. For the cold water connection (single or double) one wa­ter tap each with a 3/4" external thread is required. If this is not avail­able, only a qualified installer may connect the washing machine to
the mains water supply.

The inlet hose for cold water (blue stripes) is not intended to be
used for a hot water connection.

If the hot or hard water connection is missing, cold water consump­tion increases accordingly to account for the missing water intake.

A Y-piece for connecting two inlet hoses to a single cold water line is supplied.
