I have a 50# CSV-1 and a Square D 40/60 pressure switch. The pressure switch will be mounted on the tank "T" near the pressure tank. With the 50# CSV and the pressure switch cut off at 60; I should be good to go without any adjustments assuming the pressure switch is really set at 60psi cut off from the factory-----correct?

Sould I set the empty pressure tank 2 psi lower, (38psi), or 5-10psi lower,(30-35psi) than the cut on setting as the CSV website says?
