Connection to the water supply

 Water from the wash cabinet must not be consumed.
- The washer-disinfector must be connected to the water supply in
strict accordance with current local and national water authority
regulations.
- 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 being cleaned in
the washer-disinfector, as well as the appliance itself. If the chloride
content of the water exceeds 100 mg/l the risk of corrosion to items
being cleaned in the washer-disinfector 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.
- UK, Australia and New Zealand only: To comply with water
regulation requirements, this machine must be connected to the
potable water supply via the non-return check valve supplied with
the machine.
- The washer-disinfector is supplied as standard for connection to
cold water (blue coded hose) and optionally to hot water up to
max. 65 °C (UK: max. 60 °C) (red coded hose). Connect the inlet
hoses to the stopcock valves for cold and hot water.
- 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 stopcock.
- The minimum flow pressure for the cold water connection is
100 kPa pressure, for the hot water connection 40 kPa pressure
and for the DI water connection 30 kPa pressure.
- The recommended flow pressure is ≥ 200 kPa for the cold and
hot water connections and ≥ 200 kPa for the DI water connection in
order to avoid excessively long water intake times.
- The maximum permissible static water pressure is 1,000 kPa.
- If water pressure is not within the specified range, please contact
the Miele Customer Service Department for advice.
- More information on AD water connection can be found at the end
of this section.
- Stopcocks 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 1.7 m long pressure hoses,
DN 10, with ¾ inch screw thread. The filters in the screw threads
must not be removed.
