Requirements for the fresh water connection

Fresh water connections and their components must be made in
accordance with local regulations. From a microbiological perspective,
the fresh water must be of drinking water quality. This also applies to
treated water.
Installation components and materials must be suitable and permitted in
accordance with local regulations. A solenoid valve is integrated into the
dishwashing machine's fresh water pipe. This, together with the leakage
detector in the base drip tray in the subframe, ensures that the fresh water
supply is shut off in the event of a leak in the machine.
Recommended water hardness:
•
1–3 grains per US gallon (gpg) without GiO MODULE
•
1–20 grains per U.S. gallon (gpg) with GiO MODULE
Recommended water temperature:
•
140°F (60°C)
Colder water will result in a longer preheat time during startup and will
extend the wash cycle time. The required temperatures will still be
reached.
Pressure range of the fresh water supply flow pressure upstream of the
solenoid valve:
•
8.7–72.5 psi (0.6–5 bar)
Measures to ensure correct water pressure:
•
If the minimum flow pressure is too low, increase the pressure using a
pressure booster pump (not supplied as standard).
•
If the maximum pressure is exceeded, limit the pressure using a pressure
regulator (not supplied as standard).
Other measures:
•
Make sure that no foreign iron particles can enter the machine via the
fresh water connection. The same also applies to contamination by other
metal particles (e.g. copper shavings).
•
A dirt trap must be fitted in the fresh water supply to protect the solenoid
valve. An additional dirt trap is not required.
•
The feed hose must be sufficiently long so that the machine can be
moved for servicing purposes.
