I may have made a dumb purchase! I'm waiting for my new Pentair, 3hp 011018 Intelliflo pump/motor to arrive. However, I'm looking through the owner's manual and see that the motor is listed as a three phase motor. My electrical service from S.M.U.D. (Sacramento) is not three phase service. But I'm looking at the wiring diagram, and it looks like as long as I wire it for 230 volts (two hots, and one ground), that seems correct. I'm thinking that very few single family homes have three phase service, but the Pentair Intelliflo pump is widely used by many homeowners. Am I over thinking this? Pherhaps someone can set me straight on this. I don't want to void the warrenty, I don't see anywhere in the wiring instructions that says you must have three phase service. The pump that's in there now, I wired for 230v, but it's a single speed motor. Any advice is appreciated.
