INSTALLATION & USE
Setup Process
- Turn off power to the system and relieve any pressure in the lines before beginning installation.
- Thread the 1/2" MIP connection into the corresponding port on your softener or DI vessel using appropriate thread sealant or tape.
- Connect 110V power according to local electrical codes, ensuring all connections are secure and moisture-protected.
- Restore power and verify the light activates when conductivity rises above the 500K ohm threshold, indicating resin exhaustion.
COMPATIBILITY
System Requirements
The Clack R7031-500K Resilites light is designed for use with deionization systems and water softeners equipped with a 1/2" female threaded port for conductivity monitoring. It functions optimally in Good Water systems and other manufacturers' equipment that require a 500K ohm resistance threshold for resin bed exhaustion indication. Ensure your electrical supply matches the 110V AC requirement before installation.
🔧 Pro Tip: Test the light immediately after installation by temporarily creating a low-resistance path across the electrodes with a damp cloth—the light should activate, confirming proper electrical connection and bulb function before you put the system back into service.
