TROUBLESHOOTING - CELL
CELL
AP 700 - 7 plate cell
AP 1400 - 14 plate cell
CELL PROBLEMS
•
Needs cleaning, calcium buildup.
•
No current at cell.
•
Coating worn off of plates.
•
Damaged due to low flow, freezing, broken
or cracked fittings.
•
Shorted with foreign matter.
CELL CLEANING
• Clean the cell by submerging it in 4 parts water to 1 part muriatic acid.
• When bubbling quits, the cell is clean of calcium deposits.
• Rinse thoroughly after cleaning.
• Do not leave the cell in acid for more than 30 minutes.
TEST VOLTAGE AT THE CELL
Turn power off.
Lift cable enough to slide test probes to the
terminals.
Touch common probe to the center terminal
and the other probe to either outside termi-
nal. Make certain cable stays in contact with
terminals.
Turn on power and wait for control to call for
chlorine production.
With the cell under full load there should be
22 to 28 VDC.
If the correct voltage is present, but the cell
is not producing chlorine, manually test the
water chemistry and salt ppm. Correct any
readings out of range. If the problem contin-
ues, replace the cord and cell.
After testing is complete, press the cable
down tightly.
