Top Benefits:
Built-In Timers for Hassle-Free Scheduling
Integrated clock and dual timers let you automate pool filtration and chlorination, ensuring consistent performance without daily adjustments.
Low-Maintenance Design
The self-cleaning reverse polarity electrode reduces calcium build-up, providing years of reliable operation with minimal upkeep.
Customizable Chlorine Output
Easily adjust chlorine levels to suit your pool’s needs, with settings from 0-30% in Low Mode or 100% in Boost Mode for seasonal or high-use demands.
Ideal for Most Pools
Perfectly suited for pools up to 70,000L in mild climates, delivering efficient sanitation for a wide range of residential pools.
Key Features:
- Advanced Sanitation: State-of-the-art electrode technology ensures maximum water clarity and hygiene.
- Smart Control Modes:
- Boost Mode: One-touch activation for 24 hours of 100% chlorine output to handle high pool use or seasonal start-ups.
- Low Mode: Adjustable 0-30% output for reduced chlorine needs (e.g., during low pool use or when covered).
- Cover Mode: Automatically reduces chlorination when a compatible electric pool cover is closed, saving energy and extending cell life.
- User-Friendly Interface: Clear LED screen with warning indicators for low salt or system issues, plus simple menu navigation.
- Versatile Equipment Control: Manage pool lights or auxiliary devices (with optional relay box) and program timers for added convenience.
- Winterising Support: Adjustable output for cold weather (<10°C) to protect the cell, with easy reopening steps for seasonal use.

| Metal | N/A | < 0.10 ppm | N/A | Use 'Metal Remover' | Monthly |
* Fill pool with water from the mains water supply. Do not use rain water or well water.
** Do not add salt directly into the skimmer. Do not initiate electrolysis until salt has fully dissolved.
*** Reading is True Calcium Hardness, not Total Hardness
- Winterising Tips: For active winterising in cold weather (<18°C), reduce output and use the Zodiac Winteriser Pool Pack to prevent algae, maintain clarity, and protect equipment for 6 months. For passive winterising, shut down and drain the system.

Frequently Asked Questions:
How easy is it to install the Zodiac Ei3 24?
The Ei3 24 is designed for simple installation, fitting 40mm or 50mm PVC pipes and requiring no plumbing adjustments for Zodiac LM3 retrofits. Install horizontally with the cell inlet near the electrical lead, following the included manual. Most users can set it up in under an hour.
How often should I clean the Ei3 24 cell?
The self-cleaning reverse polarity cell minimises maintenance, typically requiring manual cleaning only every few months, depending on water chemistry. Use a Salt Chlorinator Cell Cleaner or a 1:10 hydrochloric acid solution if calcium build-up appears.
What should I do if the screen shows a "No Flow" error?
A "No Flow" error means the system has paused chlorination due to insufficient water flow. Check the filter pump, clean dirty filters or skimmers, and ensure by-pass valves are open. Verify the flow switch wiring and clear the error by holding the select button for 4 seconds after resolving the issue.
Why does the "Low Conductivity" warning appear, and how do I fix it?
The "Low Conductivity" warning, indicated by the "SALTS" LED, suggests salt levels are below 4000 ppm or the cell is calcified. Test the pool’s salt level using a test strip or take a sample to a pool shop. Add salt to reach 4000 ppm if needed, and clean the cell if calcium build-up is present. The warning clears automatically once corrected.
What does a "Check Output" error mean?
A "Check Output" error indicates a problem with the cell connection or condition. Ensure the cell power cord is securely connected. If the cell plates are worn or calcified, clean them as per the manual or consider replacing the cell. Switch off the chlorinator and check all wiring before restarting.
