Connecting the water supply

 Water from the wash cabinet must not be consumed.
- The machine must be connected to the water supply in strict accor-
dance 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 corro-
sion to items being cleaned in the machine will be further in-
creased.
- 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 con-
nection 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 con-
denser is connected to the cold water faucet.
- The minimum flow pressure for the cold water is 14.5 psi
(100 kPa) gage pressure, for the hot water 5.8 psi (40 kPa) gage
pressure and for the DI water connection it 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 the DI water connenc-
tion ≥ 29 psi (200 kPa) gage pressure, to avoid excessively long
water intake times.
- The maximum permissible static water pressure is 145 psi
(1,000 kPa).
- If water pressure is not within the specified range, please contact
Miele Service for advice.
- More information on DI water connection can be found at the end
of this section.
- Faucets with a ¾ inch screw thread must be provided on site for
the connection. The valves must be easily accessible to allow the
water inlet to be turned off when not in use.
- The water inlet hoses are approximately 5' 7" (1.7 m) long pressure
hoses, DN 10, with ¾ inch screw thread. The filters in the screw
threads must not be removed.
