Easy Installation & Maintenance

Simple Setup: Installs horizontally with correct flow orientation (cell inlet near the electrical lead). Fits 40mm or 50mm PVC pipes.

Plumbing Cell and POD assembly

Low Maintenance: Automatic self-cleaning reduces calcium build-up. For periodic manual cleaning, use Salt Chlorinator Cell Cleaner or a safe 1:10 hydrochloric acid solution. Refer to the user manual for full instructions.
Water Chemistry Matters: Maintaining proper chemical balance is essential to protect the chlorinator cell and maintain warranty coverage.

* 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: In colder months (<18°C), reduce chlorinator output and use the Zodiac Winteriser Pool Pack to prevent algae, clarify water, and protect the cell. For passive winterising, power down and fully drain the system.

The eXO iQ delivers smart automation, premium features, and long-life performance – all in one streamlined unit. It's the ideal solution for pool owners who want more control, less maintenance, and water that’s always ready to enjoy.

Frequently Asked Questions:

How do I know if my Wi-Fi signal is strong enough for installation?

Use a free Wi-Fi signal strength app on your smartphone. Stand exactly where the chlorinator will be installed and check for stable signal quality. If the signal is weak, consider installing a Wi-Fi extender near the equipment area.

Can I use mobile data (3G/4G/5G) to control the chlorinator?

Yes. Once your eXO iQ is connected to your home Wi-Fi, the iAquaLink app will work whether your phone is connected via Wi-Fi or mobile data.

What should I do if pairing fails or takes too long?

Double-check the Wi-Fi password and press the pairing button again. If the connection still fails, restart both the chlorinator and your Wi-Fi router. You can also install a Wi-Fi repeater to improve signal strength. For assistance, contact our support team.

What if I change Internet providers or replace my modem?

If your Wi-Fi name or password changes, you’ll need to re-pair your chlorinator with the new network. Follow the same steps as the initial setup in the manual or app.

What does the pH sensor do?

The eXO iQ pH model continuously monitors the water’s acidity (pH level) and automatically doses liquid acid as needed using a peristaltic pump. This helps maintain perfect balance, reducing manual testing and dosing.

Why is my chlorinator displaying a "No Flow" error?

This warning appears when insufficient water flow is detected. Check that the pump is running, clean your filter and skimmer, and ensure bypass valves are open. After resolving the issue, hold the OK button for 4 seconds to clear the message.

What does the "Check Output" warning mean?

This typically indicates a loose connection or worn-out cell. Turn off the power, check all wires and the cell plug, and clean the cell if it’s calcified. If the error persists, the cell may need replacement.

Why am I seeing a "Low Conductivity" message?

It usually means salt levels are below 4000 ppm or the cell is calcified. Use a test strip or bring a sample to your local pool shop. Add salt if needed and clean the cell to restore proper conductivity.

Why is "Overheat" showing on the screen?

This message means the internal temperature of the control unit has exceeded 85–90°C. To protect internal components, output is reduced or paused until the unit cools.

Solution: If the unit is installed outdoors, provide shade or relocate it out of direct sunlight. Chlorination will resume automatically when temperatures drop below 78°C. No manual action is required unless the issue persists repeatedly.

Why does it say "Low Water Temp" and stop chlorinating?

Chlorination is paused when the water temperature drops below 10°C. This protects the cell from unnecessary wear in cold conditions.

Solution: Chlorination will automatically resume in Low Mode between 10–15°C, and at full output above 15°C. No action is needed unless the sensor is faulty.

What does the "pH Low" message mean?

This message appears when the system detects that the pH level has dropped below 5, or if the pH sensor is disconnected, dirty, or not calibrated.

Solution: Use a test strip or photometer to verify the actual pH. Check the sensor wiring at the control box and POD, clean and recalibrate the sensor, and ensure your alkalinity is within range. If issues persist, the sensor may need to be replaced.

Why is the system flashing "pH Dosing Stop"?

This warning indicates that the system has dosed acid for 5 hours without reaching the desired pH setpoint. It may also be caused by a dirty or faulty sensor, an empty acid container, or a priming issue with the dosing pump.

Solution: Check the pH level manually, inspect the acid container and tubing, clean and recalibrate the sensor, and test the peristaltic pump if needed. If alkalinity is too high, consult a pool specialist to safely lower it.

Why is the system flashing "ORP Stop"?

This warning appears when the chlorinator is unable to reach the target ORP level after 36 cumulative hours of operation. It may be caused by sensor issues, water imbalance, or insufficient chlorine production.

Solution: Test the chlorine level manually, check sensor wiring and calibration, and inspect the cell for wear or calcium buildup. If cyanuric acid is high or chlorine effectiveness is reduced, shock the pool and rebalance. Replace the ORP sensor if needed.

No chlorine is being produced, but there’s no error message. Why?

This may happen during a reverse cycle (self-cleaning), when chlorination is paused, or if the output setting is low.

Solution: Wait a few minutes and observe the unit. If still uncertain, increase output to 100% temporarily and watch for bubble production in the cell. If no activity is visible after several minutes, check the cell connection or contact our service team.
