I'm getting ready to close the pool and this is my first winter with a PoolPilot (Auto Pilot SC-48). I've seen differing opinions on removing the cell or leaving it in the line over the winter. (The area where I live gets pretty cold through the winter--the pool will freeze solid). In the years prior to installing the Autopilot, I'd fill all the plumbing with RV antifreeze. Is that acceptable with an SWG? Will the pink antifreeze hurt the cell/manifold or the flow switch over the winter?
How have the rest of you cold weather people winterized an Auto Pilot in the past?
