Connection to the cold water inlet

The machine must be connected to

the water supply in accordance with all local and national plumbing codes.

The machine is constructed with an

air gap/anti-siphoning device on both the intake and the drain sides. No such additional devices are neces sary or recommended, as they will impede the water inflow into and out of the washer.

The water pressure must be between

35 and 145 psi (2.5 - 10.0 bar). If the water pressure is not within this range, the Miele Technical Service Department can advise you of the measures to be taken (see "Programming special functions").

^ This machine is designed for cold

water connection only. Both inlet hoses (water supply and steam condenser) must be connected to the valves for cold water. Cold water sup ply must be provided with shut off valves (by others).

Valves with 3/4’’ male hose thread should be provided near the washer, and should be easily accessible.

For additional protection of the valves against impurities in the water supply, large surface area filters are en closed in the kit supplied with the machine (see diagram in "Cleaning and care, Maintaining the filter as sembly").

Plumbing

Hose Color Water type

Blue Green

WARNING - PERSONAL INJURY HAZARD: The water in the washer/ disinfector is not suitable for drink

ing.

Drainage

The drain system is equipped with a

non-return valve which prevents dirty water from flowing back into the washer/disinfector.

^ The machine is supplied with two

5 ft (1.5 m) long flexible drain hoses with an inner diameter of 3/4’’ (2 cm). They should not be shortened or attached to any fittings that would cause a reduction in water flow.

^ Longer drain hoses up to a length of

13 ft (3.3 m) are available if required.

Both hoses can be attached to exist ing drain lines through the use of a 1-1/2’’ (3.5 cm) or larger stand pipe / P-trap combination. Alternately, the hoses can be connected directly to existing drain lines, provided any fit tings or adapters used do not reduce the water flow.

The drain hoses must not exceed 13 ft (3.3 m) in length, or be attached to the main drain at a point higher than 3 ft (1m) above the floor.

A floor drain is permissible.

Disposal of the packaging material

The transport and protective packaging is mostly manufactured from the follow ing reusable materials:

corrugated paper/cardboard

polystyrene (CFC-free)

polyethylene foil (transparent)

untreated wood

Rather than throwing these materials away, please take them to the nearest recyclables collection point.

Disposal of your old machine

Old machines contain materials which can be recycled. Please contact your

local salvage yard about potential recy cling options before disposal.

Before disposing, run the DRAIN pro gram to make sure that no residual flu ids are left in the sump of the machine.

When disposing of an old machine, make sure the door catch is removed. This will prevent children at play from being accidentally locked in.

Adjusting the water softener

To avoid the build-up of calcium depos its on items being cleaned and disin

fected in the washer/disinfector, the water may need to be softened (where the supply hardness exceeds 107 ppm CaCO3).

To ensure a steady supply of soft water, the water softener must always be:

correctly set

–

regenerated with salt as soon as the

–

REACTIVATION indicator light comes on.

The water softener should be set to cor respond with the water hardness upon installation of the washer/ disinfector.

Your local water authority can advise you on the water hardness in your ara.

Setting the water softener

The hardness range is divided into 18

units and a zero position. The washer/ disinfector is set at the factory for a water hardness setting of 8, corre sponding to 339 ppm CaCO3. If your water supply is harder or softer than this, change the setting as follows:
