Connecting the water supply

 Water from the wash cabinet must not be consumed.
– The machine must be connected to the water supply in strict
accordance with local and national water authority regulations.
– The water used must at least comply with regulations for drinking
water quality. If the water supply has a high iron content, there is a
danger of corrosion occurring on stainless steel items being
cleaned in the machine, as well as the machine itself. If the chloride
content of the water exceeds 100ppm (100 mg/l), the risk of
corrosion to items being cleaned in the machine will be further
increased.
– In certain regions (e.g. mountainous areas) the water composition
may cause precipitates to form, requiring the use of softened water
in the steam condenser.
– A backflow preventer is not required.
– In the standard version, the washer-disinfector is equipped for
connection to cold water (blue coded hose) and optionally hot
water up to max. 150°F (65°C). Connect the inlet hoses to the cold
and hot water faucets.
– If there is no hot water supply available, the inlet hose coded red
must also be connected to the cold water supply.
– The intake hose without water protection device for the steam
condenser is connected to the cold water faucet.
– The minimum flow pressure for cold water is 14.5 psi (100 kPa)
gage pressure, for hot water 5.8 psi (40 kPa) gage pressure and for
DI water connection is 4.4 psi (30 kPa) gage pressure.
– Recommended flow pressure for cold and hot water connections
is ≥ 29 psi (200 kPa) gage pressure and for DI water connection
≥ 29 psi (200 kPa) gage pressure, to avoid excessively long water
intake times.
– The maximum permitted static water pressure is 145 psi
(1,000 kPa).
– If the water pressure does not fall into the stated range, contact
Miele Service for advice.
– More information on DI water connection can be found at the end
of this section.
– A faucet valve with a ¾" threaded union 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 inlet hoses are approx. 5' 7" (1.7 m) long pressure hoses
terminating in a ¾" female thread. On no account may the inlet filter
be removed.
