Water connection
154
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 current local and national water authority
regulations.
– The water supply must at least meet the standards for drinking
water. 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 in the
water exceeds 100 mg/l, the risk of corrosion to stainless steel
items being cleaned is greatly increased.
– In certain regions (e.g. mountain regions) the water composition
may cause precipitates to form, requiring the use of softened water
for the steam condenser.
– The machine is equipped with a safety system for the protection of
drinking water and may be connected to the water supply without a
non-return valve, if national regulations permit.
– The machine is supplied as standard for connection to cold water
(blue coded hose) and optionally to hot water up to max. 65°C (red
coded hose). Connect the inlet hoses to the water shut off valves
for cold and hot water.
– If there is no hot water supply available, the inlet hose coded
red
must be connected to the cold water supply or alternatively has to
be deactivated by a Miele Service technician.
– The intake hose without water protection device for the steam
condenser is connected to the cold water tap.
– The
Minimum flow pressure
for cold water is 14.5 psi (100 kPa)
pressure, for hot water 5.8 psi (40 kPa) pressure and for DI water
connection is 4.4 psi (30 kPa) pressure.
–
Recommended flow pressure
for cold and hot water connections
is
≥
29 psi (200 kPa) pressure and for DI water connection
≥
29 psi
(200 kPa) pressure, to avoid excessively long water intake times.
– The
maximum permissible 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 tap valve with a ¾", garden hose thread and male connection,
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.
