PROBLEM
CAUSE
SOLUTION___________________________
7. Single CHECK SYSTEM Flash
A. Water exiting the filter is being diverted away from the
inlet of the flow detector
A. Increase the flow rate above 15 gallons (56 LPM) per minute to activate
the flow detector.
B. Check the condition of the filter. B. If the filter is dirty clean it.
C. Ensure that the flow detector is not installed opposite in C. Extract the flow detector & re -install if necessary.
relation to the actual water flow.
D. The flow detector may have failed.
D. Replace the flow detector.
8. Double CHECK SYSTEM Flash
A. Th e cell is scaled.
A. See # 2.
B. The cell cord is disconnected from the cell.
B. Ensure that the cell cord is firmly pressed
onto the cell.
C. Low salt
C. Check the residual salt level and adjust if necessary.
(Refer to the salt requirements needed for 3,000 ppm section, page 6).
D. The unit is not reversing polarity.
D. Send the Control Panel back to factory for
service.
E. Possible cell failure.
E. Check with either a 504 or 957 cell tester. Replace
the cell if needed. Refer to #4 of this section.
F. Very cold pool water.
F. Lower the output control dial setting, even to the "0"
position, and add a non -chlorine shock to the pool until the
water temperature increases above 60° F (14°C).
9. Triple CHECK SYSTEM flash
A. Low cell voltage.
A. Check with either a 504 or 957 cell tester. A possible cell short circuit may
exist. Replace the cell if needed. Refer to # 4 of this section.
10. Quadruple CHECK SYSTEM flash
A. No cell voltage or current.
A. Send the control panel back to the factory for service.
