Installation Notes
Isolation the pump and relieve system pressure before servicing.

Ensure the system is free of leaks and the tabs are feeding correctly.
Maintenance Tip
Check the tablet load and feed rate monthly. Inspect internal components and vents for corrosion or buildup. Replace worn check valves or gaskets, clear any blockages, and ensure the feeder is operating smoothly to maintain consistent sanitization and reduce service calls.
