Pentair 520736 Flow Switch Assembly For Intellichlor Salt Chlorine Generator; Easytouch Control System

The Pentair IntelliChlor Flow Switch Assembly, model 520736 is a replacement kit designed to restore proper water flow monitoring in Pentair saltwater chlorination systems. In these systems, the flow switch plays a critical role—it ensures that the chlorinator cell only operates when there’s sufficient water circulation. Without this safeguard, the unit might attempt to operate under low-flow conditions, which can cause reduced performance or even damage to the cell.

Below are some key details about this product:

Compatibility & Application

  • Models: The flow switch is engineered to work with several Pentair IntelliChlor salt chlorinator models, including the IC15, IC20, IC40, and IC60. It is also compatible with Pentair Easytouch Pool and Spa Automation Control Systems. This wide compatibility makes the 520736 an essential maintenance part if you’re managing any of these systems or planning a system upgrade.

  • Functionality: By detecting proper water flow, the switch helps prevent the chlorinator from operating in conditions that could lead to inefficiencies or system damage. This reliability is crucial for maintaining sanitization balance and ensuring the longevity of your pool equipment.

Installation & Replacement Process

Replacing the flow switch involves these general steps:

  1. Safety First:

    • Power Down: Ensure that the pool pump is turned off and the IntelliChlor cell is deactivated before beginning any work. This prevents accidental shocks and avoids damage to the electronic components.

  2. Removing the Old Assembly:

    • Access the Switch Compartment: Using a small Phillips screwdriver, remove the flow switch cover screw and detach the cover.

    • Detach the Cable: Loosen the flow switch cable carefully. Note the arrows on the top of the switch nut, as these indicate the proper orientation.

    • Unscrew the Assembly: Using a flat 1/2" (approximately 30 mm) wrench, gently unscrew the old flow switch assembly from the cell. The instructions emphasize caution to prevent damaging the cell’s plastic coupling.

  3. Installing the New Assembly:

    • Insertion: Insert the replacement flow switch into the threaded hole of the cell. Start by hand-tightening it.

    • Final Tightening: Carefully tighten the assembly further with the wrench until the switch thread nearly bottoms out.

    • Wiring: The kit typically includes replacement wiring components—strip back the wires on both the new flow switch cable and the old switch wire, match the corresponding colors, twist them together, and secure with the provided wire caps.

    • Reassemble: Replace the switch cover and secure it with the small Phillips screw. Once reassembled, restore power to the pool pump and IntelliChlor cell.
