Winterizing your ICO is just as important as winterizing your pool. If you wish to winterize your spa, you must also winterize your ICO SPA. Please follow this process. It's part of good practice to preserve the life and reliability of your sensors and battery.
Your ICO appliance is winterised at the same time as your pool/spa, i.e. when the water temperature is below 12°C for chlorine bromine pools and 15°C for salt pools.
Voici les étapes pour hiverner l’appareil sans oublier l’application ICO.


Step 1: Remove ICO from the water
Step 2: Clean and dry ICO
It's possible that after a season in the water, your ICO (outer shell) and probes may be covered with an oily film or impurities.
- Start by running the ICO under running water and rubbing the surfaces lightly with your hand to remove any deposits. An abrasive sponge could damage your appliance.
- Then unscrew the lower cover to gain access to the probes and rinse them in clean water (without removing them).
- Finally, dry your appliance thoroughly using only a soft cloth.
Step 3: Regenerate the pH and ORP sensors
Sensor regeneration with KCl-storage concerns pH and ORP sensors exclusively.
- Remove the lower cover
- Pour KCl storage fluid over the yellow sponges inserted in two black caps for pH and ORP/ REDOX sensors only.
- Replace the black protective caps on the probes.
- For a perfect seal, we recommend using insulating adhesive tape to prevent the KCl-storage crystallising in the black caps.
- Replace the lower cover

Step 4: Wait 12 hours and allow ICO to dry
It is now important to leave ICO to dry for 12 hours in a room at room temperature.
Step 5: Charge the battery
After this time, check the battery charge level in your ICO application. If it is below 80%, recharge your device using the USB cable supplied.
Step 6: Switch off ICO
More info on the procedure for switching ICO on and off.
- Remove the top cover and the white sub-cover
- Depending on your ICO model (ICO v1 or ICO v2):
- ICO V1: press the on/off button for about 5 seconds
- ICO V2: connect your ICO to the USB port in less than 5 seconds.
- The LED flashes red when the device is switched off.
- Replace the white sub-cover and the top cover
Step 7: Store your ICO over winter
Once your ICO has been switched off and your sensors protected, store it in a clean, dry place. The temperature of the storage room should be between 15°C and 25°C throughout the winter. A lower temperature could cause irreparable damage to the probes.
Now all you have to do is winterise the ICO application as described below until the next season!
Step 8: Activate wintering mode in the ICO application
Open the application : select your pool or spa to winterize
Click on the icon settings and then on My pool / My spa.
In the section Winteringselect Activate / Deactivate


In the section Wintering select Activate / Deactivate, and then activate « Winterize my pool /spa » and click on Continue.


When the winterizing mode is on , a snowflake icon appears on your pool profile. Access to data is temporarily disabled until your pool is opened.To reactivate your ICO, click on the snowflake then validate “end of wintering” .
