Why Use R171086

The R171086 eliminates the need for constant manual chlorination by steadily releasing sanitizing tablets into your pool or spa. It’s especially useful if you want a “set-and-forget” approach to maintaining chlorine or bromine levels — great for busy pool owners or smaller residential pools where convenience and consistent sanitation are priorities.

Usage & Maintenance Tips

  • Drop the dispenser into the pool or spa water; ensure it floats freely and is unobstructed.
  • Adjust the control ring to match the tablet dissolution rate to your pool size and usage level.
  • Monitor sanitizer levels regularly — top off or replace tablets as needed to maintain proper halogen concentration.
  • Clean periodically to remove any residue or buildup, which helps prolong dispenser lifespan and performance.
