Water Connection

In order for machine to function properly, water
service should have the following:

• Separate hot and cold lines with individual shut-

off valves.

• Hot water temperature should be a maximum of

190°F (88°C). If available water temperature is
lower, it is recommended to equip machines with
steam or electric heating.

• Water pressure should be between 30 and 85 psi

(2 to 7 bar). The machine will function properly
at lower pressure but with increased filling times.

• It is highly recommended that screen filters be

installed in water supply lines to keep rust, grit or
other foreign material out of solenoid valves.

• Suitable air cushions should be installed in

supply lines to prevent “hammering.” Refer to
Figure 16.

To connect water feeders to rear of machine, use
flexible hoses. Because this is a vibrating machine,
water lines must allow for movement or leaks may
result. Hang hoses in a large loop behind machine so
that they are not kinked or pinched. Refer to Table 1
and Table 2 for connection sizes and recommended
hose sizes.

For machines labeled with the CE mark, backsiphon
protection devices must be installed previous of all
machine water inlet valves in accordance with
accepted European standards.

To prevent personal injury, avoid contact
with inlet water temperatures higher than
125° Fahrenheit (51° Celsius) and hot
surfaces.
