Thanks again Jody.  |
the minimum pressure dial is the boost psi that the pump will start pumping water; the max pressure is the boost level that the pump is at 100% pressure. So starting around 4-5 psi or so is fine, but you should lower the max setting to 9-10 psi. By having it set at 15 psi the pump is never on all the way until 15 psi of boost, which you'll never reach.
They do this so the pump speed increases as the boost level climbs, which is a much preferred method as compared to just turning the pump on at 100% at a certain boost level. You don't need as much water at 5 psi as you do at higher levels, so they control the pump speed to ramp it up, with you controlling when it starts and ends with the min/max settings. I'd guess the center tune knob adjusts how aggressive the pump ramps up between the two for fine tuning.
