How long it lasts
Replace it when chlorine output stays low with the salt at about 4000 ppm, pH at 7.2 to 7.4, enough run time, a sound cell connection and the calcium cleaned off, Pentair says; it gives no set life.
After replacing: No reset needed. Switch the unit back on and set the output again.
