2. Safety Information

CAUTION: See back panel for additional precautionary statements.
This product contains metallic silver. Avoid contact with eyes, skin, and clothing. In case of contact, rinse thoroughly with water. If irritation persists, seek medical attention. Do not ingest. If swallowed, call a poison control center or doctor immediately.

3. Setup and Installation
The Freshwater Ag+ Continuous Silver Ion Cleaner is designed for easy installation into compatible Hot Spring, Tiger River, Hotspot, Solana, and Limelight hot tubs. Specific installation instructions may vary slightly depending on your spa model. Always refer to your spa's owner's manual for precise guidance on where to insert the silver ion cartridge.
- Ensure your spa is clean and balanced according to your spa manufacturer's recommendations before installing the new cartridge.
- Locate the designated filter or cartridge housing within your spa.
- Carefully unpackage the Freshwater Ag+ Continuous Silver Ion Cleaner.
- Insert the cartridge into the designated housing. Ensure it is securely seated.
- Once installed, the silver ions will begin to release into the spa water, providing continuous sanitization.
4. Operating Instructions
The Freshwater Ag+ Continuous Silver Ion Cleaner works passively to maintain water quality. It continuously releases silver ions into the spa water, which act as a natural sanitizer to inhibit bacterial growth and keep the water clear.
- Water Testing: Regularly test your spa water for pH, alkalinity, and calcium hardness. Maintain these levels within the recommended ranges for optimal performance of the silver ion cleaner and overall water balance.
- Supplemental Sanitizer: While the silver ion cleaner provides continuous sanitization, it is often recommended to use a small amount of a supplemental sanitizer (e.g., chlorine or bromine) as a shock treatment, especially after heavy use or if water appears cloudy. Consult your spa dealer for specific recommendations.
- Filtration: Ensure your spa's filtration system is operating correctly and that filters are cleaned regularly to support water clarity.
5. Maintenance
The Freshwater Ag+ Continuous Silver Ion Cleaner is designed for a specific lifespan, typically around four months, depending on spa usage and water chemistry. After this period, the effectiveness of the silver ions will diminish, and the cartridge should be replaced.
- Replacement: Replace the silver ion cartridge approximately every four months, or as indicated by your spa's maintenance schedule or water quality.
- Disposal: Dispose of used cartridges according to local regulations for household waste.
- Spa Cleaning: Continue with regular spa cleaning routines, including filter cleaning and periodic draining and refilling of the spa, as recommended by your spa manufacturer.
6. Troubleshooting
If you experience issues with water quality while using the Freshwater Ag+ Continuous Silver Ion Cleaner, consider the following:
- Cloudy Water:
- Check and balance your water chemistry (pH, alkalinity, calcium hardness).
- Ensure your spa filters are clean and the filtration system is running adequately.
- Perform a shock treatment with a compatible supplemental sanitizer.
- Verify the silver ion cartridge is not expired and is properly installed.
- Algae Growth:
- Increase circulation and filtration time.
- Perform a shock treatment.
- Ensure the cartridge is not expired.
- Odor:
- Perform a shock treatment.
- Check for proper water balance.
- Consider draining and refilling the spa if the odor persists.
For persistent issues, consult your authorized Hot Spring Spas dealer.
