The Jandy R0737500 Flow Switch Assembly is a genuine replacement flow sensor designed for compatible Jandy AquaPure® Ei Series electronic salt water chlorine generators. This assembly monitors water flow through the sanitizing system and helps ensure chlorine generation occurs only when proper circulation is present, protecting both the equipment and the pool system. ━━━━━━━━━━━━━━━━━━ Key Features • Genuine Jandy replacement flow switch assembly for AquaPure® Ei Series salt water chlorination systems • Designed to verify adequate water flow before chlorine generation is activated • Helps protect the salt chlorinator from operating under low-flow or no-flow conditions • Compatible with AquaPure Ei Series models including APURE35 and APURE35PLG systems • Direct replacement for discontinued and superseded flow switch assemblies including R0511900 • Supports proper sanitization system operation and diagnostic performance • Ideal for replacing failed, damaged, or worn flow switch assemblies during routine system maintenance • Professional installation is recommended to verify proper flow direction, wiring connection, and chlorinator compatibility ━━━━━━━━━━━━━━━━━━ Product Overview The Jandy R0737500 Flow Switch Assembly is engineered for use with AquaPure® Ei electronic salt water chlorine generator systems. As a critical safety and operational component, the flow switch continuously monitors circulation conditions and communicates with the chlorinator control system to confirm that sufficient water flow is present before chlorine production begins. A malfunctioning or damaged flow switch can result in chlorine generation errors, system shutdowns, or inaccurate flow detection. Replacing the flow switch assembly helps restore proper chlorinator operation and ensures the salt system functions as intended. The R0737500 is the current replacement for earlier AquaPure Ei flow switch versions and is commonly used during salt system service and maintenance. Proper installation, flow direction verification, wiring inspection, and routine system maintenance are important for dependable chlorination performance and long-term equipment reliability.
