Connection to the water inlet

,

Water in the machine is not

suitable for drinking.

–

The machine must be connected to

the water supply in accordance with

local and national water authority

regulations (WRC in the U.K.).

–

If the iron content in the water is too

high, there is a risk or corrosion

damage to instruments.

If the chloride content in the water

exceeds 100 mg/l, the risk of

corrosion damage to instruments will

increase considerably.

– The machine is constructed to

comply with German gas and water

regulations (DVGW), and may be

connected to a suitable water supply

without an extra non-return valve if

national regulations allow this.

In the UK this machine is listed as a

WRAS approved product in the

Water Fittings and Materials

Directory of products which comply

with the Water Fittings Regulations. It

is approved for mains water

connection in fluid categories 1 to 5

inclusive, when installed using the

double check valves supplied.

–

The water pressure (flow rate) must

be a minimum of 0.5 bar (50 kPa).

If the water pressure (flow rate) is

below 2 bar (200 kPa) the fill time is

automatically extended.

The max. permitted static pressure is

10 bar (1000 kPa).

If the water pressure is not in the

range of 0.5 to 10 bar (50-1000 kPa)

the p / 6 indicator light may come

on and the fault code "F..E" show in

the display. Please contact the Miele

Service Department.

–

The machine is supplied as standard

for connection to a cold or a hot

water supply up to a max.

temperature of 70 °C.

AD-water connection (H

2

O pure) see

next page.

– Stopcocks with 3/4 BSP male thread

are to be provided on site. They

should be easily accessible so that

the water supply can be turned off

when the machine is not in use.

–

The DN 10 inlet hose is approx.

1.7 m long terminating in a 3/4 inch

female thread. On no account must

the inlet filters be removed.

–

Large surface area filters are

enclosed in the kit supplied with the

machine for installing between the

stopcock and the inlet hose

(see illustration in "Cleaning and

Care - Water inlet").

The large surface area filter for AD

water is made from chrome nickel

steel and can be recognised by the

matt top surface.
