Pentair Max-E-Therm/MasterTemp Pressure Switch, 3A, ASME (473716Z) topsides and R185B heater applications whereMonitor water pressure conditions in compatible ASME heater applications with this 3A pressure switch. The switch helps confirm that required flow or pressure conditions are present before the heater continues operating, supporting both equipment performance and system safety. This replacement is useful when heater diagnostics point to pressure switch failure, inconsistent readings, or shutdowns caused by a worn sensor circuit. It should be evaluated
