Hey Guys, I have a job on an "island" to do, everything will be run on solar. The customer has his own grunfos 3" sqf solar pump which will be put in a 4" well. He has a strange Sq D reverse pressure switch that came with it. On the box of the switch it has off at 30 psi and on at 50psi, thought it was a misprint. Took a look at it and the points are "open" out of the box. Any ideas? Never put in a solar system before. Customer will be instaling the panels and hooking up the control box which looks like the cu-301. I will be installing the tank,pitless and hanging his pump. Suprised it dosent run w/ a transducer like the sqe does. Do I need to wire in the standard switch in series w/ the reverse switch?
