Possible front board service condition or unit
not correctly wired to 120 VAC.
Possible backboard service condition.
Flow sensor service condition or fl ow sensor
is unplugged.

qualifi ed service representative.
Flow/Salinity Sensor indicates water
temperature at sensor above 108ºF (42°C).
Reduce water temperature.
Verify proper fl ow/temp/salinity sensor
installation (see Section 3, Figure 10). Check
salinity with Myron "L" meter calibrated for
NaCl or test strips. Add salt as necessary (see
Section 4.6).
