FOX K3 F4S1/M3 MIN/MAX PRESSURE SWITCH WITH CONNECTOR - 1/4"

FOX K3 F4S1/M3 MAXIMUM/MINIMUM PRESSURE SWITCH
Operating Instructions: Maximum pressure switch / minimum pressure switch

MAXIMUM PRESSURE SWITCH
The maximum pressure switch is used to automatically turn the booster pump on and off in systems with a storage tank or in systems that operate with solenoid valves or float switches. Once the system reaches pressure, the pressure switch opens the contact to the pump, preventing it from operating unnecessarily.

MINIMUM PRESSURE SWITCH
The minimum pressure switch is used to automatically turn the systems on and off. The minimum pressure switch detects the presence or absence of incoming water flow, thus preventing the pump from operating during periods of water shortage.
