Installation & Usage Notes
Prior to use, fill the dispenser with the appropriate number of 1″ tablets. Set the control dial to a low rate to begin, monitor sanitizer levels over 24-48 hours, then adjust the dial upward if needed. Place the dispenser in the water so it floats freely and away from skimmer suction or return jets for even distribution. Periodically inspect the dispenser, refill tablets, and adjust the feed as the season progresses.
Maintenance Tips
- Inspect the dispenser casing for cracking, flotation integrity or chemical-damage—replace if any damage is found.
- Check water chemistry regularly, and if sanitizer levels decline even though the dispenser is full and dialed high, increase the feed rate or consider an inline feeder for larger pools.
- Store the unit in a dry, shaded place when not in use to preserve the foam fill and prevent deformation.
Why Choose This Dispenser?
For pool service professionals, spa technicians and retail inventory, the Pentair R171090 offers a cost-effective, simple solution for localized or secondary chemical dispensers. Its floating design and adjustable rate make it ideal for maintenance zones, spas or smaller pools where full-scale inline feeders are overkill.
