After a very successful first season, Fall approaches and the inevitable pool closing draws nearer. While the PB is going to be coming back to close this first season, I have been wondering about the Intellichlor ic40 cell. We're in Northern Illinois, and winters can be brutal. Does anyone recommend installing a bypass when closing their pool for the winter? Since the Cell is a self-contained electronic part, and I'm wondering if it could possibly help avoid premature failure down the line?
