Function and benefits Monitors water flow in salt chlorine pool systems and signals the chlorine generator to run only when adequate flow is present. Helps prevent the generator from running dry, reducing the risk of equipment damage and unnecessary wear. Simple, reliable operation that restores proper flow sensing when an original flow switch fails. Key features Flow sensing switch designed for salt chlorine systems. One end uses a standard phone jack connection for plugandplay replacement. Includes a circular gasket and sealing tape to improve the connection seal and installation reliability. Fewer integral parts for simplified maintenance and longer service life. Compatibility Suitable as a replacement for part GLXFLORP and compatible with GLXFLORP, GLXFLOHP, Q12DSC2, OPTF/S. Works with many salt chlorine controllers and systems including Pro Logic, Mineral Springs MS10 and MS11, Aqua Plus, Aqua Rite XL, Aqua Logic, Aqua Rite Pro, Aqua Rite compatible units, H40, SwimPurePlus, SplashCLEAR, SmartPure, and Splash SP40. Designed to fit most Hward Goldline style salt systems that use the listed replacement part numbers. Installation and performance Easy to install with minimal tools and few components. Installation steps: unplug the existing flow sensor, insert the two ends of the switch and cable into the correct positions, wrap sealing tape as needed, and screw the switch into the pump run port without overtightening. Typical installation time can be under a few minutes for a straightforward swap. Reliable switching performance restores correct chlorine generator interlock based on actual pool water flow. Practical specifications Connection: standard phone jack style plug on one end. Includes circular gasket and sealing tape to improve fit and sealing during installation. Compact design for direct replacement of common flow sensor locations. Typical applications and use scenarios a failed flow switch on a residential salt chlorine pool controller to restore automated chlorine generation. Swap the flow sensor after pump replacement or during routine pool equipment servicing to ensure the generator only runs when flow is present. Install as part of system troubleshooting when a controller reports no flow or when the chlorinator will not activate despite the pump running. What makes this product stand out Direct replacement compatibility with common part numbers reduces downtime and avoids complex rewiring. Minimal parts and straightforward installation reduce service time and the need for professional intervention. Designed specifically for salt chlorine systems that require a reliable flow interlock to protect equipment operation. Notes Follow the pool equipment manufacturer instructions for installation and torque recommendations. Do not overtighten the switch fitting to avoid damage to threads or the housing.
