Maintenance
1. Water Quality Management
Regularly test the water chemistry using appropriate test strips. Maintain proper pH levels and sanitize the water according to recommended guidelines for inflatable hot tubs to ensure a hygienic environment.

- Once empty, clean the interior surfaces with a soft cloth and mild, non-abrasive cleaner. Rinse thoroughly.
- Ensure the hot tub is completely dry before deflating and storing.
4. Cover Care

- Retain heat and reduce energy consumption.
- Minimize water evaporation.

Troubleshooting
If you encounter issues with your hot tub, refer to the following general troubleshooting steps:
