INSTALLATION & USE
Replacement Procedure
- Shut off water supply to the softener and disconnect power to the control valve before beginning work.
- Remove the brine tank lid and carefully disconnect the existing float assembly from the safety float valve.
- Install the new Clack H4640-320 float assembly, ensuring both grommets are properly seated to prevent salt bridging and debris interference.
- Verify the float moves freely through its full range of motion without obstruction, then restore power and water supply.
- Monitor the first regeneration cycle to confirm proper brine fill levels and automatic shutoff function.
COMPATIBILITY
System Requirements
This 32-inch float assembly is designed specifically for Clack control valve systems and standard brine tanks requiring a longer float configuration. The H4640-320 is compatible with Clack WS1, WS1.25, WS1.5, and similar models using safety float assemblies. Verify your brine tank height and existing float length before ordering to ensure proper fit and operation. The included grommets provide universal compatibility with most Clack valve configurations.
🔧 Pro Tip: Before installing the new float assembly, clean the inside of your brine tank and inspect the salt grid for damage. A clean tank ensures the float operates smoothly and extends the life of your replacement part.
