Plumbing

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 strict accordance
with current local and national water
authority regulations.
– If the iron content in the water is too
high, there is a risk 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.
– If there are too many impurities in the
local water supply, it will be
necessary to operate the steam
condenser with demineralised water.
– 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
100 kPa (1.0 bar) and with an AD
water connection it is 60 kPa (0.6
bar).
74
– The recommended flow pressure
for a cold and hot water connection
is 250 kPa (2.5 bar) and for an AD
water connection is
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 (the
indicator light may come on and the
fault code F E will appear in the
display) please contact Miele for
advice.
– 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.
Connect the inlet hoses 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 inlet hose for the steam
condensor (without non-return valve)
must only be connected to the cold
water stopcock.
– AD water connection - see the
following 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.
