6. Maintenance and Cleaning
Regular maintenance ensures the longevity and hygiene of your sauna.
- After Each Use: Wipe down the interior waterproof floor and walls with a clean, dry cloth to remove any moisture or condensation.
- Steamer Cleaning: Periodically clean the interior of the steamer to prevent mineral buildup. Unplug the steamer, allow it to cool, and then drain any remaining water. Wipe the interior with a damp cloth.
- Storage: When not in use, ensure the sauna tent is completely dry. Disassemble the frame and fold the tent flat for compact storage in a cool, dry place.
7. Troubleshooting
- No Steam Production: Ensure the steamer is filled with water above the minimum level and below the maximum level. Check that the power cord is securely plugged in and the unit is turned on with a timer set. Verify the lid is tightly closed.
- Insufficient Heat: Confirm the temperature setting is at a higher level (e.g., P9). Ensure all zippers on the sauna tent are fully closed to prevent heat loss.
- Remote Control Not Working: Check the batteries in the remote control. Ensure there are no obstructions between the remote and the steamer unit.
- Water Leakage: Verify that all hose connections are secure and the steam box is correctly positioned. Ensure the steamer lid is properly sealed.
