Q: Good morning my autopilot light is blinking and read low amp -cell? What can b the problem thank you

Asked by: Francesco Castelli - 7/6/2022
A: According to the manual, “LOW AMPS – CELL” means that purifier still producing, but these are the possible issues. 1) Low cell amperage from a cell that is heavily scaled. If cell is already clean, replace cell. 2) Pool has low salt and the unit needs salt calibration. Add salt to pool, recalibrate salt sensor. 3) The Cell Cord is Loose. Ensure that the cord is firmly pressed into the cell and the wires properly connected into the banana plugs.

Q: I recently purchased ppc3 salt cell and installed it and working great. I had it on 24 boost and the display was showing cleaning cell for short period of time. Does it clean it self ?

Asked by: Tony Duke - 7/13/2022
A: Salt chlorinators are "reverse polarity", indicating that from time to time they reverse the direction of electric current in the cell. This helps inhibit/slow the build up of mineral scaling inside the cell.
