Connecting the water supply
The water in the dishwasher is NOT safe to drink!
– The Commercial Dishwasher's connection to the water supply
system must be in compliance with local codes.
– The water used must at least comply with national 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 Commercial Dishwasher, as well as the machine itself. If the
chloride content of the water exceeds 100 mg/l, the risk of
corrosion to items being cleaned in the dishwasher will be further
increased.
– In certain regions (e.g., mountainous areas), the typical water
composition can cause precipitates to form, which in turn requires
the use of softened water for the Commercial Dishwasher.
– A device for preventing the return flow of water is not necessary, as
this Commercial Dishwasher conforms to the applicable standards
for the protection of drinking water.
– The water intake pressure must amount to at least 29 psi (200 kPa)
overpressure. If the pressure is below 29 psi (200 kPa), the water
intake time is extended automatically. The maximum permissible
static pressure amounts to 145 psi (1000 kPa) (overpressure). If the
water intake pressure does not lie in the 29-145 psi (200-1000 kPa)
range, contact Miele Technical Service for advice.
– The Commercial Dishwasher is supplied as standard for connection
to cold water (blue coded hose)
and
hot water up to 149°F (65°C)
(red coded hose). Connect the intake hoses to the faucets for cold
and hot water.
– If no hot water supply is available, the intake hose with the
red
marking must also be connected to the cold water supply.
– A faucet with a 3/4 inch male thread must be provided on site. The
valve should be easily accessible, since the water supply should be
shut off whenever the dishwasher is not in use.
– The DN 10 intake hose is approx. 5'7" (1.7 m) long, terminating in a
3/4 inch female thread. A 4' 11" (1.5 m) long flexible metal
extension hose tested to 2,030 psi (14,000 kPa) is available as an
optional accessory if required. On no account may the intake filter
in the female thread be removed.
– Install the large-surface filter (included in the accessory pack)
between the faucet and the intake hose
(see “Cleaning and care, Water intake”).
