Water Connection - Figure 22
Please read the first three points of the safety
instructions and warnings before connecting the
appliance to the main water supply.
• The water pressure must be between 21.8-
87.0 psi (1.5-6 bar).
Use a 1/4" OD copper line to connect the water
supply to the solenoid valve. Allow extra length
to the water supply line to provide slack for easy
removal and to prevent the line from kinking.
This is not supplied with the appliance
(Figure 22).
• A shut-off valve, such as the saddle valve
illustration here, must be installed between the
hose line and the main water supply so the
water supply can be stopped if necessary.
Do not install the shut-off valve behind the
appliance.

• If you have hard water, we recommend you install
a water softener. Also, a filter must be installed if
the water contains solids such as sand.
• All equipment and devices used to supply the
water to the appliance must comply with the
current regulations for your geographical area.
