5. Bedienungsanleitung
Once installed and filled with water, operating your Edesa One water heater is straightforward.
Erstinbetriebnahme:
- Ensure the tank is completely filled with water (as per installation step 6).
- Connect the water heater to the main power supply.
- Use the external temperature regulation knob to set your desired water temperature. For energy saving, it is recommended to set the temperature to the lowest comfortable level.
- The water heater will begin heating the water. The heating time will vary depending on the initial water temperature and the selected setting.
Temperatureinstellung:
The external knob allows you to easily adjust the water temperature. Turning the knob clockwise typically increases the temperature, while turning it counter-clockwise decreases it. Adjust the temperature as needed for comfort and energy efficiency.
6. Wartung
Regular maintenance ensures the longevity and efficient operation of your Edesa One water heater.
- Anode Inspection/Replacement: The magnesium anode protects the tank from corrosion. Thanks to the O'PRO system, its lifespan is extended. However, it should still be inspected periodically (e.g., every 1-2 years, depending on water quality) and replaced by a qualified technician if significantly depleted.
- Draining and Descaling: In areas with hard water, mineral deposits can accumulate inside the tank. Periodically draining and descaling the tank (e.g., annually) can prevent efficiency loss and damage. This procedure should be performed by a qualified technician.
- Sicherheitsventilprüfung: Periodically check the safety valve to ensure it is not blocked and functions correctly. Follow manufacturer guidelines for testing.
- Außenreinigung: Reinigen Sie die Außenseite des Warmwasserbereiters mit einem weichen, fusselfreien Tuch.amp Tuch. Keine Scheuer- oder Lösungsmittel verwenden.
Vorsicht: Always disconnect the water heater from the power supply before performing any maintenance.
