Possible Cause
Incorrect pH causing metals to come out of
solution.
High total hardness.
Possible Cause
Low current in forward direction to cell.
Low current in reverse direction to cell.
Extremely low current to cell.
Higher than normal current to cell.
Cell needs to be cleaned.
Low current in forward direction and VAC
input voltage below 100/200 VAC.
Low current in reverse direction and VAC
input voltage below 100/200 VAC.
Low salinity (below 2.0 gpl).
High salinity (above 4.0 gpl).
Possible front board service condition or unit
not correctly wired to 120 VAC.
Possible backboard service condition.
Flow sensor service condition or flow sensor
is unplugged.
Low VAC input voltage and on board power
supply is not regulated or unit not correctly
wired.
Pool temperature is too high for operation of
Nature
Fusion Soft.
2
Flow sensor air lock condition or very low
salinity.
ENGLISH
Corrective Action
Adjust total alkalinity to 80 - 120 ppm.
Then adjust pH to within the range 7.4 -
7.6. See Section 4.5.
Dilute pool with fresh water. Contact a
qualified service representative regarding
use of a sequestering agent.
Corrective Action
1. Clean cell if necessary (see Section 6.5).
2. Check DC Cord.
1. Clean cell if necessary (see Section 6.5).
2. Check DC Cord.
1. Clean or replace cell if necessary (see
Section 6.5).
2. Check DC Cord.
Contact a qualified service representative.
Clean cell if necessary (see Section 6.5).
Contact a qualified service representative.
Contact a qualified service representative.
Add salt to pool to achieve 3.0 gpl (see Section
4.6).
Backwash filter if a DE filter is installed.
Partially drain pool and dilute with fresh water
until salinity returns to 3.0 to 3.5 gpl.
Contact a qualified service representative.
Contact a qualified service representative.
Contact a qualified service representative.
Unit wired to improper AC voltage. Contact a
qualified service representative.
Flow/Salinity Sensor indicates water
temperature at sensor above 108ºF (42°C).
Reduce water temperature.
Verify proper flow/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).
