NOTE: Factory set pressure range settings are +/- 8 psi. A mechanical pressure switch factory set, can not be more accurate and field adjustments may be needed. (This is not a defect). The maximum operating pressure of pump and system the switch is to be used with, must be a minimum of 12 psi above the switch shut off setting, or more. Use of this switch outside of the noted parameters will not be warranted. Pressure switches overheated or burned up inside, due to rapid cycling will not be warranted.
