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.
