Cold water connection ISO 228/1 DN 20 (G3/4”).
4-15°C 39°F-59°F 150 - 700 kPa (21.7 - 101.5 PSI / 1.5 - 7 bar) at 0.07 gal/sec (0.3 l/sec).
Hot water connection ISO 228/1 DN 20 (G3/4").
150 - 700 kPa (21.7 - 101.5 PSI / 1.5 - 7 bar) at 0.07 gal/sec (0.3 l/sec).
The supply water temperature is related to the machine setup.
MACHINES WITH BOILER:
MACHINES WITHOUT BOILER:
If the water pressure is less than 150 kPa (21.7 PSI - 1.5
bar) a booster pump must be installed ahead of the
machine.
This pump can be requested as an optional, and if
ordered together with the machine it is supplied already
installed on the water connection fitting. If the pressure
at one of the unions exceeds 700 kPa (101.5 PSI - 7bar),
a pressure reducing valve must be installed on the inlet
piping. Connection pipes with anti-return protection and
check valve and stop cock are available as optional
accessories.
If the water hardness exceeds 14°fH/8°dH/10°cH, install
a softener filter on the dishwasher inlet connection pip-
ing to ensure efficient machine operation.
Connect the appliance water supply to the mains, fitting
a cut-off cock, a filter and a pressure gauge between the
appliance and the mains.
