If your CircuPool CORE Series Salt Chlorinator is exhibiting a red Low Salt light, first independently measure the salt level with two or more different tests and adjust the salinity to 3500-4000ppm if needed.
If the salinity level independently tests in range, the Cell may be accumulating mineral scaling or other debris that needs to be removed. Clean the Cell according to the instructions in the manual; it may be necessary to clean the cell multiple times.
In addition, there may be air bubbles around the salinity sensor (upper backside of the cell). This may happen if there is air in the pipelines or for a few minutes at initial startup. Wait until the air bubble disappears. Take steps to ensure the pump doesn’t lose prime and that pockets of air aren’t forming due to other equipment. Clean filters and strainers. Check the water level in the pool, especially at skimmers/suction points. Check for closed valves, pump cavitation, a faulty or failing pump, etc. Ensure at least 20 GPM water flow (approximate). If a Variable Speed Pump is in use, incrementally raise the RPM’s of its lowest setting until an air pocket does not form. Lastly, loosen the side collars, slightly tilt the entire unit to lean the controls back, (hopefully) removing the air bubble from the salinity sensor and then re-tightening the collars when finished.
If the salt level is ideal, no air is accumulating around the sensor, and the cell has been thoroughly cleaned multiple times in a row, the cell plates or salinity sensor may be damaged. At this point, you should call the technical support team weekdays at (888) 206-9938 between 9-4:30 Central for further assistance.
