- Carefully lift the heater unit and hang it onto the mounted bracket, ensuring it is stable and level.
5.3 Electrical Connection
WARNING: This step must be performed by a licensed electrician.
- Connect the heater to a dedicated 220-240V, 2-phase, 60Hz electrical circuit with appropriate amperage and circuit breaker protection.
- Follow the wiring diagram provided with the heater and controller for correct connections.
- Ensure all connections are tight and insulated.
5.4 Placing Sauna Stones
Arrange sauna stones (not included) in the stone compartment of the heater. Ensure good air circulation between the stones. Do not pack them too tightly. Use only genuine sauna stones designed for electric heaters.
5.5 Installing the Digital Controller (NTS-100)
Mount the NTS-100 digital controller on an exterior wall outside the sauna room, at a convenient height. Connect the controller to the heater and temperature sensor according to the wiring diagram. The controller allows for easy temperature and time adjustments.
6. Operating Instructions
The NTS-100 digital controller provides intuitive control over your sauna heater.
6.1 Initial Start-Up
- After installation, turn on the main power supply to the sauna heater.
- The digital controller display will illuminate.
- For the first use, operate the heater for 30-60 minutes without water to burn off any manufacturing residues. Ensure good ventilation during this period.
6.2 Using the NTS-100 Digital Controller
- Power On/Off: Press the power button to activate or deactivate the heater.
- Temperature Setting: Use the up/down arrows to adjust the desired sauna temperature. The display will show the set temperature and the current sauna temperature.
- Timer Setting: Press the timer button to set the operating duration. The heater will automatically shut off after the set time.
- Pre-set Time: Some controllers allow for a delayed start. Consult the controller's specific instructions for this feature.
6.3 Wet vs. Dry Sauna Use
- Dry Sauna: Operate the heater without pouring water on the stones. This provides a dry heat experience.
- Wet Sauna: For a wet sauna experience, carefully ladle small amounts of water onto the hot sauna stones. This creates steam and increases humidity. Do not pour large quantities of water at once.
7. Maintenance
Regular maintenance ensures the longevity and safe operation of your sauna heater.
7.1 Cleaning the Heater
- Ensure the heater is completely cool and disconnected from power before cleaning.
- Wipe the exterior stainless steel surfaces with a damp cloth. Do not use abrasive cleaners or solvents.
- Remove any debris from the stone compartment.
7.2 Sauna Stone Inspection and Replacement
- Periodically inspect the sauna stones for signs of crumbling or deterioration. Over time, stones can break down due to repeated heating and cooling cycles.
- Replace any broken or worn-out stones to maintain optimal heat transfer and prevent damage to the heating elements.
- Rearrange stones annually to ensure good air circulation.
8. Troubleshooting
If you encounter issues with your sauna heater, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
