Installation Instructions
- Turn off power and relieve system pressure before servicing.
- Remove the existing clamp and inspect all components for wear.

- Ensure the spring and washers are properly seated on both sides of the clamp.
- Tighten the barrel nut evenly until firm tension is achieved, but do not over-tighten.
- After installation, pressurize the system and check for leaks.
Troubleshooting
- Leak at clamp joint: Verify even tightening and proper seating of the O-ring between tank halves.
- Loose clamp: Ensure the spring is not compressed beyond normal range and the nut threads are clean.
- Uneven clamp pressure: Confirm washers are flat and properly aligned before tightening.
Maintenance Tip
Inspect the spring and nut assembly every time the filter tank is opened. Replace the components if you notice rust, deformation, or loss of spring tension. Proper clamp tension helps maintain a safe and watertight seal on the filter tank.
