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.
With ophthalmic instruments ensure that the demineralised water
has low levels of endotoxins/pyrogens.
– 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 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 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 cold water is 100kPa (UK:
200kPa) pressure, for hot water 40kPa (UK: 200kPa) pressure and
for AD water connection is 30kPa (UK: 200kPa) pressure.
– Recommended flow pressure for cold and hot water connections
is ≥200kPa pressure and for AD water connection ≥200kPa
pressure, to avoid excessively long water intake times.
– The maximum permissible static water pressure is 1,000kPa
pressure.
– If the water pressure does not fall into the stated range contact
Miele Service for advice.
– More information on AD water connection can be found at the end
of this section.
– A stopcock 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.
