Turn the pump breaker off.I have no clue what the low cut out would be, how would I test that?
Remove the cover from the Square-D.
Watch the pressure gauge and the contacts while you drain the tank.
You will see the contacts close. The gauge will indicate the cut-in setting.
Continue draining the tank. The contacts will open. The gauge will indicate the low cut-out pressure.
Close the draincock.
Put the cover back on. Turn the breaker back on. Hold the reset lever "just so" until the pressure exceeds the low cut-out pressure.
