Restarting your ICO after winterizing

If you have winterised your pool/spa and your ICO, we invite you to follow this step-by-step guide to restart your ICO and the application. This procedure is necessary to get the new season off to a good start.

Step 1: Charge ICO

Charge your ICO's battery for 6 to 8 hours, using the USB cable supplied.

During the charging time, you can carry out steps 2 to 5.

Step 2: Update your ICO application

On your smartphone, open the ICO application. An updated version of your application may be available.

Step 3: Deactivate the wintering mode

On the ICO application, deactivate the Winter mode.

Step 4: Update the software

On your application, in the ICO block, check whether there is a small red exclamation mark. If this is the case, an update of your ICO software may be available. Install it by following the instructions. It is essential to place your mobile phone close to your ICO. This will keep Bluetooth connectivity active.

Find out more about updating your software.

Step 5: Switch on ICO

At the end of the battery charge, when you disconnect ICO from the USB cable, ICO will automatically turn itself back on.

Step 6: Regenerate your ICO's pH and ORP sensors

Regenerating the probes rewets the sensor bulb glass and recharges the electrolyte solution it contains. Use the KCl (potassium chloride - storage) liquid included in the Ondilo calibration kit. En savoir plus sur la régénération des sondes.

• Unscrew the lower part of your ICO to access the pH and ORP probes.
• Remove the 2 black caps
• Pour the liquid KCl into the black plugs on the yellow sponges to soak them in the solution.
• Leave both probes immersed for at least 1 hour.
• Once the hour has elapsed, rinse your probes with mineral water.
• Proceed to the calibration step.

Step 7: Calibrate your ICO's pH and ORP sensors

This step is necessary at the start of each season to guarantee the quality of the measurements and maintain your ICO. Get the calibration kit.

Please refer to the assistance page dedicated to probe calibrationwhich explains everything in detail.

• Perform the calibration in a room at room temperature (recommended temperature is 25°C / 77°F).
• Place your ICO next to your smartphone
• On the application, click on the Remote Control button and select pH Probe Calibration.
• Calibrating the pH probe requires 2 measurements, with a change of solution. Start with the pH4 solution, then with the pH7 solution. When you have completed the 2 steps, ICO checks the consistency of the measurements and may give you an error message if they differ.
• Finish by calibrating the ORP probe with the ORP solution.

Step 8: Putting ICO back in the water

You can now put ICO back in your pool or spa. Your appliance will automatically start measuring water quality. After 6 hours (i.e. 6 measurements), ICO will be able to give you an initial recommendation for improving water quality, if necessary.

ICO is now ready to monitor water quality! All you have to do now is follow its recommendations for a carefree swimming season.
