I am very familiar with electrical connections and have wired subpanels, transfer switches, booster pumps, etc. BUT, I am having an issue with a new Pentair Whisperflo 3/4 HP pump (WFE-3). I am wiring the pump with 115V. On the pump motor, it states that is wired for 230V at the factory but 115V can be used if you move the BROWN wire to terminal B, the white wire to L2 and then connect line voltage to L1 and L2. I quadruple checked that I have the pump wired exactly as listed but as soon as I hit the ON switch, the 20A AFCI pops and I barely hear a tick out of the pump. I checked the pump impeller and it rotates freely.
I noticed that the placard on the pump doesn't refer to 230V and 115V but rather high voltage and low voltage. Since I am wiring 115V, I am assuming that I should wire in accordance with the low voltage instructions.
Does anyone have any ideas???? Would someone be kind enough to check their 115V Pentair Whisperflo and see how you are wired?? THANKS
