I paid someone to install my Polaris SWG but after watching them, I certainly could have done it myself. Mine is a 230v unit wired into an Intermatic mechanical timer which supplies power to pump and SWG. Then I just set the SWG controller to generate a selected number of hours. My Autoclear has very few bells and whistles. Besides the adjustment for hours to generate, there is a button for running a test. The test gives volts drawn, amps drawn, and a system code of 90, 91, or 92. 90 indicates no issues found and the others indicate possible problems. Last, there is a yellow light that will flash to indicate 'low salt'. Performance has been excellent but it would be nice to have some of those other features. Bought mine new-in-box on ebay for $450 delivered. Quite happy!
