Operating instructions

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
damage to instruments.
If the chloride content of the water
exceeds 100mg/l the risk of
corrosion damage to instruments will
increase considerably.
– If there are too many impurities in the
local water supply it will be
necessary to operate the steam
condenser with de-mineralised
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 water connection is 100 kPa
(1.0 bar) and with an AD water
connection it is 60 kPa (0.6 bar).
–
The recommended flow pressure
for a cold 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 (the p / 6
indicator light may come on and the
fault code F E will appear in the
display) please contact the Miele
Service Department for advice.
–
This machine is supplied as standard
for connection to a cold water
supply. The inlet hose must only be
connected to the cold water
stopcock.
– AD water connection - see the
following page.
– A stopcock with 3/4 inch male thread
must be provided on site. It 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 filter 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 "Maintenance -
Cleaning the filters in the wash
cabinet'"). The large surface area
filter is made from chrome nickel
steel and can be recognised by the
matt top surface.
