Thanks for your help. I will have my certified electrician do it, I just didn't want to spend good dollars on the unit and then find out some pool installation knowledge was needed (above and beyond the basic plumbing hookups).
Also, did you follow the plumbing diagram shown in the owners manual? It looks like it shows both a Hartford loop and a check valve.... anyone know if I need both? My old unit had check valve in internal plumbing and no Hartford loop so I'm not sure. BTW - I do not have a chemical feeder...use BBB method!
