Connection to the water inlet

,
The water in the machine must
not be used as drinking water.
– The machine must be connected to
the water supply in accordance with
local and national water authority
regulations.
– If the water supply has a high iron
content there is a danger of
corrosion occuring on items being
processed in the machine, as well as
in the machine itself.
If the chloride content of the water
exceeds 100mg/l the risk of
corrosion to items being processed
in the machine will be further
increased.
– This machine is constructed to
comply with German water
regulations (DVGW), and may be
connected to a suitable supply
without an extra non-return valve if
national regulations permit.
– The minimum flow pressure for a
cold and hot water connection is
150 kPa (1.5 bar) and with an AD wa-
ter connection it is 60 kPa (0.6 bar).
– The recommended flow pressure
for a cold and hot water connection
is 0 250 kPa (2.5 bar) and for an AD
water connection is 0 150 kPa (1.5
bar). Otherwise fill times will be too
long.

– The maximum permitted static wa-
ter pressure is 1000 kPa (10 bar).
– If the water pressure is not in the
range specified above, please
contact the Miele Service
Department for advice.
(The message "CHECK WATER
INLET" may light up in the display).
– The machine is supplied as standard
for connection to a cold (coded blue)
and a hot (coded red) water supply
up to a max. temperature of 70 °C.
The inlet hoses should be connected
to the stopcocks for the hot and cold
water supplies. The steam
condenser inlet hose (without water-
proof connector) should be
connected to the cold water
stopcock.
– If a hot water supply is not available
the inlet hose coded red should also
be connected to the cold water
stopcock. AD-water connection
(marked H O pur) 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 hoses are approx.
1.7 m long terminating in a 3/4 inch
female thread. On no account must
the inlet filters be removed.
