• 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 cur-
rent regulations for your geographical area.
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. This is not sup-
plied with the appliance (Figure 22).
• A shut-off valve, such as the saddle valve illus-
tration here, must be installed between the hose
line and the main water supply so the water sup-
ply can be stopped if necessary.
Do not install the shut-off valve behind the
appliance.
