- Attach the mounting bracket securely to the wall using appropriate fasteners.
- Hang the heater onto the mounting bracket. The design allows the heater to be mounted low on the wall, which helps distribute heat evenly.
3.2 Elektrische Anschlüsse
All electrical work must be carried out by a certified electrician.
- The electrical connections are made from the side of the heater.
- Ensure the power supply matches the heater's requirements: 400 V 3N~ / 2N~ or 230 V 1N~.
- Use appropriate connection cables: 5 x 1.5 mm² or 3 x 2.5 mm².
- Install the correct fuses: 3 x 10 A or 1 x 20 A.
- Connect the heater to a separate control unit (not included). Refer to the control unit's manual for specific wiring instructions.
3.3 Platzierung der Saunasteine
- Before first use, carefully place the sauna stones into the stone compartment. The maximum stone capacity is 25 kg.
- Use stones with a diameter of 5–10 cm.
- Arrange the stones loosely to allow for good air circulation through the heater. Do not pack them tightly.
- Ensure stones do not cover the air vents or touch the heating elements directly in a way that obstructs heat flow.

4. Bedienungsanleitung
The Harvia Vega BC45E is controlled by a separate external control unit. Refer to the instruction manual provided with your specific control unit for detailed operating procedures.
- Ein-/Ausschalten: Use the external control unit to switch the heater on and off.
- Temperatureinstellung: Set the desired sauna temperature using the thermostat on the control unit.
- Erhitzungszeit: The control unit typically allows you to set a pre-heating time or a continuous operation period.
- Water on Stones: Once the stones are hot, you may gently ladle small amounts of water onto them to create steam (löyly). Use only clean tap water. Do not pour excessive amounts of water at once, as this can damage the heating elements.
- Nach Gebrauch: Always switch off the heater using the control unit after your sauna session. Allow the heater and stones to cool down completely before leaving the sauna unattended.
5. Wartung
Regular maintenance ensures the longevity and safe operation of your Harvia Vega BC45E heater.
- Saunasteine: Inspect the sauna stones at least once a year, or more frequently with heavy use. Replace any cracked, crumbling, or discolored stones. Over time, stones can disintegrate and impede air circulation, affecting heater performance.
- Reinigung: The exterior of the heater can be wiped with a damp cloth. Do not use abrasive cleaners or solvents. Ensure the heater is completely cool and disconnected from power before cleaning.
- Belüftung: Periodically check that the sauna's ventilation openings are clear and unobstructed.
- Elektrische Anschlüsse: Have a qualified electrician periodically check the electrical connections for any signs of wear or loosening.
6. Fehlerbehebung
If your Harvia Vega BC45E heater is not functioning as expected, consider the following common issues:
- Heizung heizt nicht:
- Check the external control unit: Ensure it is powered on and the temperature is set correctly.
- Check the circuit breaker/fuses: Verify that the main power supply to the sauna and heater is active and that no fuses have blown.
- Inspect heating elements: Visually check if any heating elements are visibly damaged or broken. If so, contact a qualified service technician.
- Unzureichende Wärme:
- Check sauna stones: Ensure stones are properly arranged and not packed too tightly, which can restrict airflow. Replace old, crumbling stones.
- Sauna room insulation: Verify that the sauna room is adequately insulated and sealed. Drafts or poor insulation can lead to heat loss.
- Sauna size: Confirm that the heater's power (4.5 kW) is appropriate for your sauna volume (3-6 m³).
- Overheating/Safety Cut-out:
- The heater has an overheating protection. If it trips, allow the heater to cool down. Consult the control unit manual for instructions on resetting the safety cut-out.
