Direct replacement for trusted Pentair acid washing routines

Meet the Eiahonen 520670 acid washing kit, designed as a precise replacement for the Pentair Intellichlor acid washing kit 520670/523103. It's compatible with IC60, IC40, IC20, and IC15 models, so you can rely on a seamless fit across your system.

Built to endure, designed for performance

Constructed from high-strength, chemically resistant plastic, the kit resists corrosion and embrittlement even with repeated exposure to acidic cleaners. This durability helps you complete multiple cleaning cycles without worrying about wear.

  • Stable material that withstands repeated contact with cleaning solutions
  • Accurate fit that minimizes leaks and downtime
  • Long-lasting components including robust O-rings

How it supports system efficiency

Calcium buildup can reduce efficiency and shorten electrolyzer life. Regular use of this kit targets scale buildup, potentially restoring performance and helping your IntelliChlor reach its intended output.

  • Scale removal helps maintain electrode clarity
  • May help prevent common error codes such as Inspect Cell
  • Supports extended life of the chlorination system

Easy, tool-free installation and use

With an easy-to-grip design, you can tighten or loosen by hand. The included O-rings seal securely for a safe, leak-proof cleaning environment, reducing downtime and getting your pool back to clarity faster.

Simple acid wash steps at a glance

  1. Disconnect power and isolate the IntelliChlor unit.
  2. Pre-clean the calcium buildup in the cell.
  3. In a plastic container, mix water and hydrochloric acid at 4:1 (acid added to water).
  4. Screw the cleaning kit onto the cell’s threaded end.
  5. Fill with acid solution until the blades and probes are covered; soak under 30 minutes.
  6. Rinse thoroughly with fresh water; repeat if scale remains; reassemble and restore power.

Always follow the included instructions to ensure safe handling of acids and to protect your equipment.
