Applications & Compatibility
This feeder is ideal for large pool installations—either high-use residential or smaller commercial setups—that require a reliable automatic feeder for chlorine or bromine tablet systems. Ensure your pool’s tablet chemistry and plumbing configuration match the feeder’s requirements.
Installation Instructions
- Shutdown pool pump and isolate feeder plumbing before servicing.
- Install the feeder in an off-line supply line, sized at 1 inch, with bypass or flow control as required.
- Fill the feeder chamber with the appropriate tablets (chlorine or bromine) and adjust the feed valve to the manufacturer’s recommended setting.
- Begin circulation and confirm adequate chemical feed and stable sanitizer levels over the first 24-48 hours.
Troubleshooting
- Sanitizer levels too low: Check tablet type, feed valve setting, and flow rate through the feeder unit.
- Sanitizer levels fluctuating: Confirm that the feeder is installed off-line properly and that there is no bypass flow around the unit.
- Leaks around feeder body: Ensure correct union tightness, seal condition and tube orientation.
Maintenance Tip
Regularly inspect the feeder chamber for tablet depletion and buildup of residue. Clean the valve and inspect seals annually. Keeping the feeder properly maintained helps prevent large swings in sanitizer levels and protects the longevity of your pool equipment.
