Regenerate ICO sensors

Regenerating ICO probes with a KCl solution is an essential step in the maintenance of your pH and ORP probes. It ensures their reliability and extends their service life. Probe regeneration is one of the maintenance tips recommended by Ondilo. It affects the warranty period of your probes.

It is compulsory for the following three stages:

• during the first use of your appliance , ICO Pool V2 et ICO Spa V2,
• during the restarting your ICO device in spring
• and finally at the time of theWinterising your ICO.

1. Use KCl solution when first starting up your ICO

You have just purchased an ICO Pool V2 or ICO Spa V2 device. A KCl solution to regenerate your pH and ORP sensors is included in your ICO box. This step must be carried out before the first use of your ICO to guarantee the reliability of the measurements of your sensors.

You'll also find KCl-storage liquid in the Ondilo store for the next wintering season.

Start by downloading the ICO application and scanning the QRCode in the box. This will identify your ICO device. Then follow the recommendations in your application to regenerate the two sensors.

• Unscrew the bottom part of your ICO to access the sensors.
• Pour a few drops of KCl solution into the black caps to soak the little yellow sponges inside.
• Immerse both sensors in the liquid for 1 hour.

Continue with the rest of the installation by following the instructions in the ICO application.

You can follow the entire assistance procedure for completing the installation steps for your ICO here.

Don't forget to validate the regeneration procedure for your sensors in your application, in order to maintain the warranty.

Spring: regenerate and calibrate your sensors when you restart your pool

When restarting your pool (or spa) and ICO for the season, use the KCl regeneration solution before calibrating your sensors.

Step 1: Regenerate sensors

After charging your ICO for 8 hours on the mains, switch it on. Access the sensors by unscrewing the bottom part of your instrument. Soak the pH and ORP sensors in KCl solution for at least 1 hour, pouring the liquid over the sponges in the black caps. Finally, rinse the sensors with demineralized water.

Step 2: Calibrate sensors

Now proceed to the calibration of your pH and ORP sensors, using the pH4, pH7 and ORP calibration kit solutions in that order. To perform the calibration of your sensors, click on the remote control menu of your ICO application, then on pH sensor calibration. Follow your application's instructions. On this page you'll find all steps to calibrate your sensors.

3. Winter: store sensors with KCl during ICO winter storage.

KCl is a winterizing solution that preserves your probes over winter. Remember to order your KCL solution in our Ondilo shop!

Step 1: Prepare your sensors for winter with KCl

After getting out of the water and turning off your ICO device.

• Unscrew the lower part of your ICO to access the pH and ORP probes
• Rinse the pH (blue sensor) and ORP (yellow/orange sensor) sensors with distilled water.
• Pour a few drops of KCL solution onto the yellow sponges in the black caps to soak them thoroughly.
• Repeat the operation every 60 days (2 months) throughout the wintering period.

Step 2: Put ICO in winterization mode and store your device

Once you have validated the regeneration process in your application, you can activate the wintering mode in your application. Ensure that your unit is stored in a clean, dry and frost-free place. Learn more aboutICO winterization.
