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
water 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
water 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 appear 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.
– If a hot water supply is not available
the inlet hose coded
red
should also
be connected to the cold water
stopcock.
– The AD inlet hose is coded with "H
2
O
pur".
– 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.
– Large surface area filters should be
fitted between the stopcock and the
inlet hose (see "Problem solving").
The large surface area filter for AD
water is made from chrome nickel
steel and can be recognised by the
matt top surface.
