1. Choose a suitable location
Ground selection: Make sure the ground is flat and solid to support the weight of the sauna. Avoid installing in low-lying or water-logged areas.
Ventilation and privacy: Choose a place with good ventilation and privacy protection, and avoid placing the sauna where strong winds blow directly into it.

2. Preparation
Measure the space: Accurately measure the installation area to ensure there is enough room for assembly and future maintenance.
Check the power supply: If using an electric heater, make sure there is a suitable power connection near the site and that it meets local electrical safety standards.

3. Preparation before assembly
Check the components: Before assembly, confirm all parts are included and undamaged, including wall panels, benches/seats, heater, hardware, etc.
Tool preparation: Prepare the required tools such as screwdrivers, an electric drill, a level, measuring tape, and any tools listed in the manual.

4. Installation steps
Ground foundation: Ensure the ground is dry and level. Add a moisture barrier or floor mats if needed.
Wall installation: Install the walls step by step following the instructions/video, making sure panels are securely connected to the base and roof.
Heating system: When installing the heater, follow the heater manual to ensure safe wiring connections and confirm the heater placement meets ventilation and clearance requirements.
Seats and accessories: Install benches and accessories according to the diagram to ensure a secure fit and comfortable layout.

5. Sealing and insulation
Sealing: Ensure doors and windows/glass panels seal properly to reduce heat loss and help keep moisture out.
Insulation: Confirm any insulation components are installed correctly to improve heat retention and comfort.

6. Ventilation system
Exhaust vents: Install/confirm exhaust vents for proper air circulation and to prevent moisture buildup.
Air intake vents: Ensure intake vents are positioned correctly to bring fresh air into the sauna.

7. Electrical inspection
Safety test: After installation, test the electrical system (heater and control panel) to ensure normal operation and no safety issues.
Grounding measures: Confirm the electrical system is properly grounded to reduce the risk of electrical faults.

8. Cleaning and inspection
Internal cleaning: Clean the interior to remove dust, packaging, and any installation residue.
Functional test: Perform a full test run to verify the heater, controls, and any lighting operate correctly.

9. Preparation for use
Preheat the sauna: Before first use, run a preheat cycle to confirm temperature control performance and allow the interior to dry completely.
User guide: Read and follow the user guide to ensure safe operation.

10. Regular maintenance
Inspection and maintenance: Regularly inspect the structure and electrical system to keep the sauna operating safely.
Cleaning and maintenance: Clean wood surfaces and components routinely to keep the sauna sanitary and looking its best.

By following these installation tips, you can help ensure a smooth setup and a safe, comfortable sauna experience. If you have any questions or need assistance, please contact our support team at support@thermalfrontier.com

Care And Maintenance

1. Regular cleaning
Floors and walls: Wipe down floors and walls with warm water and a mild, neutral soap. Avoid harsh chemical cleaners to protect the wood.
Seats and armrests: Clean with a damp cloth and mild detergent. If the surface becomes rough, lightly sand with fine-grit sandpaper to keep it smooth.
Ceiling and lamps: Prevent moisture buildup around lights, wipe the ceiling occasionally, and keep surfaces as dry as possible.

2. Ventilation
After each use, air out the sauna to reduce moisture and help prevent mold and bacteria. Open the door and any vents/windows and allow airflow until the interior is fully dry.

3. Check the condition of the wood
Inspect the wood regularly for cracks, warping, or signs of deterioration. Replace any damaged boards promptly. Avoid oil-based wood products unless specifically recommended, as they can affect heating performance.

4. Control humidity and temperature
Use appropriate temperature and humidity settings and avoid extreme conditions for extended periods to help extend the life of the wood. If possible, use a thermometer and hygrometer to monitor levels. A common recommended range is 40%–60% humidity and 70°C–100°C.

5. Heater maintenance
Keep the heater free of dust and debris to maintain efficient performance. Use the correct sauna stones and replace them according to the manufacturer’s recommendations.
For electric heaters, periodically check that wiring and connections are secure to prevent electrical issues.

6. Prevent mold and bacteria
Use a sauna-safe anti-mold/anti-bacterial product as needed, especially in areas that stay damp.
Consider removable wood or plastic floor mats so you can lift them out for cleaning and drying.

7. Regular inspection and maintenance
Create a routine inspection plan for key components such as the wood, heater, and electrical system. Depending on usage, a professional inspection every year or every few years is recommended.

8. Maintain doors and windows
Check seals regularly to prevent air leaks and heat loss. Lubricate hinges, handles, and locks as needed so doors and windows open and close smoothly.
