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 (WRAS in the
U.K.).
UK only:
To comply with WRAS requirements,
this machine must be connected to
the potable water supply via
non-return valves supplied with the
machine.
– The water used must at least comply
with European regulations for
drinking water quality. If the water
supply has a high iron content there
is a danger of corrosion occurring on
items processed in the machine.
If the chloride content in the water
exceeds 100 mg/l, the risk of
corrosion damage to instruments will
increase considerably.
– 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 - see the following page.
– 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).
– 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 (the
p
/
6
indicator light may come on and the
fault code F E will appear in the
display) please contact Miele for
advice.
– A stopcock with 3/4" BSP male
thread is to 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 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 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 for AD water is made from
chrome nickel steel, and can be
recognised by the matt top surface.
