Maintenance
1. Water Chemistry
Maintain proper water chemistry using the ChemConnect chemical floater. Regularly test the water and add appropriate chemicals (e.g., chlorine or bromine) to keep the water clean and safe. Refer to chemical manufacturer guidelines for dosage.
2. Filter Cartridge
The filter cartridges (Type VI) should be cleaned regularly (e.g., rinsed with a hose a few times a week) and replaced every few weeks, depending on usage, to ensure efficient filtration.
3. Spa Cover
Always use the reinforced spa cover when the hot tub is not in use. This helps retain heat, keeps debris out, and improves safety. Secure the cover using the buckles.

4. Freeze Shield™
The Freeze Shield automatic heating function activates when the ambient temperature drops to prevent internal components from freezing. Ensure the spa remains plugged in during cold weather to allow this feature to operate.
Troubleshooting
- E03 Error Code: This often indicates a dirty or clogged filter cartridge. Clean or replace the filter cartridge and restart the pump.
- Spa Not Heating / Slow Heating:
- Ensure the spa cover is properly secured to minimize heat loss.
- Check that the filter cartridge is clean.
- In colder climates (below 50°F / 10°C), the heater may struggle to maintain or reach the desired temperature. The spa is not recommended for use below 39°F (4°C).
- AirJet System Not Working: Ensure the pump is properly connected and powered. Check for any blockages in the air blower system.
- Water Leaks: Check all hose connections for tightness. Use the provided repair patch for small punctures in the spa liner.
For persistent issues, consult the full manufacturer's manual or contact Coleman customer support.
