Installation and planning notes

Installation requirements

The washing machine must be installed by Miele Service or by
properly trained staff of an authorized dealer.

 This washing machine must be installed in accordance with all rel-

evant 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.

Installation and planning notes

Installation

This washing machine must be transported to its installation site us­ing a suitable pallet jack. 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 for this
machine, 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 2" (50mm) on each
side to allow for movement during operation. To ensure suitable ac­cess for further maintenance and service work, please ensure a mini­mum distance of 16" (400mm) is maintained between the back of the
machine and the wall.

Installation on concrete base

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

The concrete materials and the durability of the concrete base 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 base 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 base using

the fixtures and fastenings supplied.

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

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

PW 811 / PW 814 / PW 818 5

Installation and planning notes

Leveling the machine

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

justable feet and a spirit level.

The washing machine must stand perfectly level on all four feet to
ensure safe and proper operation. Otherwise water and energy con­sumption will be increased and the machine could move.

 After aligning the machine tighten the lock nuts by turning them in a

counterclockwise direction with a wrench. This will prevent the feet
from moving.

Securing the machine

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

base using the fixtures and fastenings supplied.

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

Installation and planning notes

Installation of steam-heated washing machines

 The steam connection must only be carried out by a registered
installer. 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 service.

With steam-heated washing machines a condensate trap is required
for the condensate drain. 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, preparation 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 steam 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 responsi-

ble 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.

 The washing machine must be connected to an electrical 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 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.

Installation and planning notes

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

dance 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.

PW 811 / PW 814 / PW 818 11

Installation and planning notes

Water connection

The washing machine complies with current local and national
safety regulations protecting the drinking water supply and can
therefore be connected to the drinking water supply without a non­return valve.

The machine is designed to operate with a supply pressure of be­tween 14.5psi (1bar) and must not exceed 145psi (10bar). If it is
highter than 145psi (10bar) 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 faucet slowly and check for leaks.
Correct the position of the seal and union if necessary.

Cold water con­nection

Hot water con­nection

A supply faucet with ¾" threaded union is required for each connec­tion to the water supply (single or double). If this is not present, the
washing machine should be connected to the water supply by a qual­ified plumber.

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

To minimize energy consumption during operation with hot water,
the washing machine should be connected to a hot water ring cir­cuit.

So-called "transmission lines" (single lines 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
water up again.

Use the inlet hose supplied (red stripes) for the hot water connection.

The temperature of the water intake must not exceed 158°F (70°C).

If there is no hot water supply at the installation location for the wash­ing machine, the connection hose must nevertheless be connected to
the cold water supply. A Y-piece is required in this case. The cold wa­ter 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 (without a
separate cold water intake).

Even if a hot water connection is present, the washing machine
must be connected to a cold water intake.

12 PW 811 / PW 814 / PW 818

Installation and planning notes

Drain valve

A motorized dump valve is used to drain the machine. A 2¾" angle
connector can be used for draining the machine directly into the
waste water system (without a siphon) or into an on-site gully (with
odor trap). The dump 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, it should

be large enough to allow all machines to drain simultaneously.
The appropriate Mieleinstallation set M.-No.:05238090 is avail-

able from Miele for venting a 2¾"(DN70) pipe.
If the slope for drainage is extremely steep, the piping must be

vented so prevent formation of a vacuum in the machine's drain
system.

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

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

Avoid direct contact.

PW 811 / PW 814 / PW 818 13

Installation and planning notes

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 for viscous agents. These connectors are
sealed and need to be drilled out before connection with a
5/16" (8mm) drill bit.

Make sure that you only drill through the first panel(I) as there is a
deflecting panel(II) 3/8"(10mm) behind it.

Connections 3 to12 are for liquid dispensing. These connections are
sealed and must be cut to the diameter of the hose with a small saw.

If opened connections 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 automatically for washing machines fitted
with a multifunction module.

A flowmeter or throughput sensors can be connected for precise
monitoring of the dispensing quantity.

Connections for level monitoring are available for every agent dis­pensed.
