But today brings another problem. It's not generating chlorine for a really unexpected reason. The box says its too cold so it's quit. The pool water temp is 56 degrees, the box says it's 55 and the book says it won't generate chlorine at 50. That and the salt level discrepancy is too much. They called this morning and they're going to send me out a new entire unit. If that doesn't work better, I'll be asking for a full refund. I have some suspicions that the control box wasn't new--it had some scrapes on the window and the seal is all messed up. They assured it was truly not a used or refurbished unit, but I have my doubts.This info is great, keep it coming bud! (its crazy that we have nearly identical setups.....)
