Strong chemical smell or eye/skin irritation when using the spa.

Health caution: Limit exposure until water chemistry is corrected.

• Test water: Check free and combined chlorine/bromine, pH, and alkalinity.
• Shock and aerate: If combined chlorine is high, shock the spa and run jets with the cover open to allow gases to dissipate.
• Adjust pH: Bring pH into the 7.2–7.6 range using pH increaser or decreaser as needed.

For indoor Hanscraft spas, ensure adequate room ventilation to prevent buildup of chemical vapors.
