120
Low current in forward direction to cell.
1. Clean cell if necessary (see Section 6.5).
2. Check DC Cord.
121
Low current in reverse direction to cell.
1. Clean cell if necessary (see Section 6.5).
2. Check DC Cord.
123
Extremely low current to cell.
1. Clean or replace cell if necessary (see
Section 6.5).
2. Check DC Cord.
124
Higher than normal current to cell.
Contact a quali
fi
ed service representative.
125
Cell needs to be cleaned.
Clean cell if necessary (see Section 6.5).
126
Low current in forward direction and VAC
input voltage below 100/200 VAC.
Contact a quali
fi
ed service representative.
127
Low current in reverse direction and VAC
input voltage below 100/200 VAC.
Contact a quali
fi
ed service representative.
144
Low salinity (below 2.0 gpl).
Add salt to pool to achieve 3.0 gpl (see Section
4.6).
145
High salinity (above 4.0 gpl).
Backwash
fi
lter if a DE
fi
lter is installed.
Partially drain pool and dilute with fresh water
until salinity returns to 3.0 to 3.5 gpl.
170
Possible front board service condition or unit
not correctly wired to 120 VAC.
Contact a quali
fi
ed service representative.
171
Possible backboard service condition.
Contact a quali
fi
ed service representative.
172
Flow sensor service condition or
fl
ow sensor
is unplugged.
Contact a quali
fi
ed service representative.
173
Low VAC input voltage and on board power
supply is not regulated or unit not correctly
wired.
Unit wired to improper AC voltage. Contact a
quali

174
Pool temperature is too high for operation of
Nature
2
Fusion Soft.
Flow/Salinity Sensor indicates water
temperature at sensor above 108ºF (42°C).
Reduce water temperature.
175
Flow sensor air lock condition or very low
salinity.
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).
