Winterize your spa and your ICO

Unlike pools, winterizing an outdoor spa is less common because many of you enjoy its benefits in a snowy setting! However, in regions where frost is common, the cold can damage the tank or the hydraulic system. In this case, winterizing an outdoor spa is highly recommended.

Finally, you should know that to maintain the water at an ideal temperature in winter, your spa consumes more energy: be aware of the increase in your electricity costs!

Here are our tips for protecting your hot tub or inflatable spa from freezing. Don't forget to winterize your ICO device and app too!

Protect an outdoor spa from frost in winter

Passive or active winterization ?

If you have an embedded or hard-shell spa you can choose to winterize your outdoor spa in passive or active mode.

  1. Active winterization: this involves keeping your outdoor spa filled with water. You will need to activate the filtration and treat the water regularly over the winter.
  2. Passive winterization: if winters are particularly vigorous in your area with repeated freezing episodes, turning off your spa after draining the water completely is recommended.

If you have an inflatable spa, go to the dedicated paragraph below.

1. Winterize your outdoor spa in active mode

  • The right time from early to late October depending on the temperatures in your area.
  • Draining: Start by draining the water from your spa completely.
  • Cleaning: apply the quarterly cleaning procedure (tank, lid and water line) without forgetting to clean the filter and change the cartridge if needed.
  • Add water: Refill your spa with water (about 2/3 full).
  • Check the pH: it should be between 7.2 and 7.9 .
  • Water temperature: raise the water temperature to 35°C
  • Disinfection: add your usual disinfectant (salt, bromine, chlorine,...)
  • Filtration: activate filtration for 8 hours.
  • Winterization product: pour the product according to the manufacturer's directions directly into the water to prevent scaling, algae and other bacteria.
  • Set the filtration time to one hour per day.
  • Cover your spa with a suitable cover.

2. Winterize your outdoor spa in passive mode

  • The right time? As soon as the water temperature reaches 12°C.
  • Turn off the power then turn off the waterjets.
  • Drain all the water: you can use either a flow-through method (if your spa is equipped with a suitable valve) or a pool vacuum pump, along with a suitable garden hose.
  • Cleaning: apply the quarterly cleaning procedure (tank, lid and water line) without forgetting to clean the filter and change the cartridge if needed.
  • Remove filters: after thorough cleaning, dry them thoroughly. Store them in a clean, dry place until the next season.
  • Purge the pumps and pipes (hydraulic circuit): using a vacuum cleaner or cloth, clean and dry carefully to preserve them from freezing. There should be no trace of moisture left!
  • Cover your spa with a suitable cover.

3. Winterize an inflatable spa

  • The right time? Early to late October. Choose a sunny day to dry your spa.
  • Unplug the power
  • Drain all the water: open the drain valve and connect it to a suitable garden hose.
  • Clean the shell and mat: Clean the outside and inside of the spa with a damp sponge and cleaner, not to mention the floor mat.
  • Remove filters: after thorough cleaning, dry them thoroughly. Store them in a clean, dry place until the next season.
  • Dry the structure with a soft cloth. If possible, leave your hot tub in the sun to prevent mold from forming during storage time.
  • Deflate and store the structure in a dry place using the manufacturer's recommendations.

Winterize your ICO device

  • Winterize your ICO device: ICO:
    • Take ICO out of the water: dry it properly with a soft cloth
    • Open the top cover: long press (5-6s) to turn it off. The LED will flash yellow once. Replace the cover.
    • Remove the bottom cover of ICO: (turn it left a quarter turn and remove it)
    • Replace the sensor covers (black caps) that came with your ICO. Make sure the sponges are moistened and placed on the pH and ORP sensors (Blue and Orange/Yellow).
    • Put the bottom cover back on:store ICO in its protected box away from dust.
    • To protect the probes in winter , we recommend moistening the sponges every two months with mineral water, then putting them back into the black protective caps.
  • Final step: winterize your ICO app
    • Open the application go to the list of spas and select the desired profile
    • Click on the icon settings and then on My pool / My spa
    • In the section Wintering select Activate / Deactivate, and then activate « Winterize my pool /spa » and click on Continue.

Check your spa profile : winterization is properly activated if a snowflake appears, your ICO is now on standby. (Data access is temporarily disabled until your spa is restarted. To reactivate your ICO, click on the snowflake and confirm).
