4.2 Turning On the Heater
- Ensure the sauna room is clear of any obstructions and that the door is closed.
- Turn the temperature control dial to your desired sauna temperature.
- Turn the timer dial to the desired operating time. The heater will begin to heat up.
4.3 Timer Functionality
The built-in timer allows you to set the heater to operate for a specific duration. Please note that the timer on this unit is designed for a maximum continuous operation of one hour before automatically shutting off. If a longer heating period is desired, the timer must be reset after the initial hour.
4.4 Pouring Water on Stones
Once the stones are hot, you may gently pour small amounts of clean tap water over them to create steam (löyly). Do not pour excessive amounts of water at once, as this can damage the heating elements and pose a burn risk.
5. Maintenance
5.1 Regular Cleaning
Ensure the heater is completely cool and disconnected from power before cleaning. Wipe the stainless steel exterior with a damp cloth. Do not use abrasive cleaners or solvents.
5.2 Stone Inspection and Replacement
Periodically inspect the sauna stones for signs of crumbling or deterioration. Over time, stones can break down, which may affect heating efficiency and air circulation. Replace any damaged stones with new, genuine Harvia sauna stones. The durable structure and technical features of the heater are designed to extend its lifespan, but proper stone maintenance is crucial.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Heater does not turn on. | No power supply, circuit breaker tripped, timer not set. | Check power connection, reset circuit breaker, ensure timer is set correctly. Consult an electrician if issues persist. |
