LOW CHLORINE LEVEL IN POOL
IMPORTANT: Measuring a low chlorine level does not indicate that your system is not working. Water chemistry and environmental
conditions are the #1 cause of a low chlorine level in a saltwater pool. The following steps will enable you to verify with certainty
whether or not your system is operational and creating chlorine. Following that, this help guide will help identify what may contributing
to the low chlorine level in the pool water.
Verifying that the system is operational
There are two variables involved in the generation of chlorine: salt and electricity. If there is salt in the water and power being sent to
the Electrolytic Cell, the system is generating chlorine normally. If the salt level is in question, independently test a water sample.

Verifying Power is present in Cell
1. Ensure no Warning Lights are on (inhibiting Power in the cell)
o Is the Water Flow LED indicator illuminated? If it is, the system is not able to send power through the cell because
the Flow Sensor is not being triggered by the flow of water. See Page 9 for troubleshooting.
o Is the Check Cell or Low Salt LED indicator illuminated? If it is, the system is not able to send power through the cell
because of excess mineral build-up inside of the cell or improper salt levels. See Page 10 for troubleshooting.
o Is the System Error LED indicator illuminated solidly? If it is, the system is detecting an ongoing issue or critical fault
and has stopped sending power through the Cell. See troubleshooting beginning on Page 12.
2. Confirming Power in the Cell (measuring cell current)
o If all warning lights are off, power is successfully able to pass through the cell. For further confirmation, the Control
Module has a built-in power meter that verifies that the full & normal amount of power is able to pass through the cell.
o To verify the power being sent through the cell, turn the chlorine output setting up to 100% for diagnostic purposes.
To access the power reading, press and hold the BOOST button for three seconds to display the "Cell Current" reading
(Water Flow LED indicator will now be ON).
▪ The power graph LED lights will begin to alternate back and forth with the Power (ON/OFF) LED light.
▪ Count the number of chlorine level LED’s when the Power LED is on, and when the Power LED is off.
• Example: 5 chlorine level LED’s lit with the Power LED on, and 7 chlorine level LED’s lit with the
Power LED off = 5.7 cell amps
o As long as you can confirm that there is a "Cell Current" reading (often 5-6 when turned up to 100%), the system is
successfully able to pass power through the Cell, and is operating normally and creating chlorine.
Summary: If salt is present above the minimum level of 3000 ppm, if the no warning lights are illuminated solidly, and if "Cell
Current" reads normal when the system is turned up to 100%, then the system is fully operational and creating chlorine
normally. If a low chlorine level persists after continued operation, see the next pages to troubleshoot common causes of
high chlorine demand.
