Ozone generator not bubbling or ozone indicator not lit.

Safety: Turn off power before working on the ozonator or tubing.

• Check settings: Ensure ozone is enabled in the spa’s programming (if applicable).
• Inspect tubing: Follow the ozone tubing from the ozonator to the injector. Straighten kinks and replace brittle tubing.
• Check check valve: Replace the ozone check valve if it is clogged or allows water to backflow.
• Replace ozonator: If the ozonator indicator never lights and no output is detected, replace it with a Canadian Spa Company-compatible ozone generator.
