- 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.
