Pentair – iChlor Salt Chlorinator Flow Switch Replacement Kit

The Pentair iChlor Flow Switch Replacement Kit (R520812) is a genuine OEM part designed to restore accurate flow detection to your Pentair iChlor salt chlorine generator. The flow switch monitors water movement through the cell and automatically halts chlorine production when flow is insufficient, protecting both the cell and your pool equipment from damage.

A faulty flow switch is a common cause of the iChlor’s “FLO” fault condition, where the unit enters a safety lock and stops producing chlorine. Replacing it with this genuine Pentair kit restores normal operation and brings your system back to full efficiency.

Compatibility

This replacement kit is specifically designed for the Pentair iChlor 15 (model 523080) and iChlor 30 (model 523081) salt chlorine generators. It is not intended for use with the IntelliChlor IC series (IC15, IC40, IC60). Always verify your iChlor model number before ordering to ensure a correct fit.

Why genuine matters

As an original Pentair part, the R520812 is manufactured to OEM tolerances, ensuring precise flow detection thresholds and a perfect mechanical fit within your existing plumbing. Aftermarket alternatives may not trigger at the correct flow rate, risking dry-run conditions or false shutdowns that reduce chlorine output and cell lifespan.

Installation

The flow switch integrates directly into the iChlor cell body and connects via its existing wiring harness. While the procedure is straightforward for experienced pool technicians, we recommend consulting the Pentair iChlor installation guide or a qualified pool professional to ensure correct fitment and safe electrical connection.
