Finally got my Compupool SWG installed, but not without excitement. I mounted and wired the control unit okay. Then I cut the return line and started a geyser of water. It quickly dawned on me that the return fittings are about a foot above where I cut. One flash flood later, I blocked the returns with plastic bags under the fittings. My neat job site turned into a swamp, but the unit works great. After a week, FC is holding at 5. I like it!
