Product overview This replacement flow switch (model GLXFLORP) monitors pool water flow for salt chlorine generator systems and signals the control unit so chlorination runs only when there is adequate flow. It is a direct replacement for several common flow sensor models and includes a 15 foot extension cord with a standard phone jack for easy connection. Key benefits Restores proper flow sensing so the salt chlorine generator runs only when the pump is operating. Protects pool equipment by preventing chlorinator operation during low or no flow conditions. Simple, fast installation reduces downtime; many installs take under 5 minutes. Compatible with a wide range of salt chlorination and control systems for straightforward replacement. Compatibility Compatible with the following systems and replacement part numbers: Hayward Goldline salt chlorine generator systems Aqua Rite, Aqua Rite XL, Aqua Rite Pro, Aqua Logic, Aqua Plus Swim Pure Plus, H40, Pro Logic Mineral Springs MS10, MS11 Replacement part numbers: GLXFLORP, GLXFLORP, GLXFLOHP, Q12DSC2, OPTF/S Function and performance Detects water flow and sends a signal to the control box so chlorine generation only occurs when flow is present. Helps prevent equipment damage by ensuring the chlorinator pauses during low flow or when the pump is off. One end uses a standard phone jack connection for the control panel; includes a circular gasket and tape for improved sealing. Easy installation (step by step) 1. Turn off timer power and switch off the circuit breaker feeding the pool equipment. 2. Confirm the arrow on the flow switch matches the direction of water flow. If unsure, check the arrow on the Tee housing. 3. Insert the flow switch into the Tee housing, press the two posts together and slide the unit into the small opening. Do not overtighten. 4. Plug the phone jack into the control panel. 5. Restore power to the circuit breaker and timer. Operation notes After power up, confirm the control box indicators: the power indicator and generate indicator should light when the system is operating normally. The No Flow indicator may flash briefly; it can take about one minute after startup for the No Flow indicator to stop flashing.
