- Avoid locations exposed to freezing temperatures.
- The ultra-slim design facilitates installation in confined spaces.
3.3 Plumbing Connections
Connect the water inlet and outlet pipes according to the markings on the appliance. Use appropriate fittings and sealants to prevent leaks. A pressure relief valve must be installed on the cold water inlet line.
3.4 Electrical Connection
The appliance requires a wired electric power source. Ensure the electrical installation complies with local electrical codes. Connect the water heater to a dedicated circuit with appropriate overcurrent protection. Verify that the voltage and frequency match the appliance's requirements.
3.5 Wi-Fi Module Setup
The integrated Wi-Fi module allows for remote control. Download the 'Egea Smart' App from your device's app store. Follow the in-app instructions to connect your water heater to your home Wi-Fi network and register the device. This will enable remote monitoring and control of settings.
4. Operating Instructions
4.1 Initial Start-up
- Ensure the water heater is completely filled with water before switching on the power. Open a hot water tap to allow air to escape until water flows steadily.
- Connect the appliance to the electrical supply.
- The water heater will begin heating the water to the default temperature setting.
4.2 SMART Electronic Control
The SMART electronic control system automatically optimizes energy consumption based on your usage patterns. It learns your hot water demands and adjusts heating cycles to provide hot water when needed, reducing energy waste. You can typically override or adjust these settings via the control panel on the unit or through the 'Egea Smart' App.
4.3 Remote Management with Egea Smart App
Once connected to Wi-Fi, use the 'Egea Smart' App to:
- Monitor the current water temperature.
- Adjust the desired temperature setting.
- Set heating schedules.
- Activate special modes (e.g., Eco mode, Boost mode).
- Receive notifications and status updates.
Refer to the 'Egea Smart' App's help section for detailed instructions on its features and functionalities.
5. Maintenance
Regular maintenance ensures the longevity and efficient operation of your Ferroli water heater. Always disconnect the power supply before performing any maintenance.
5.1 Scale Reduction (BLUE FOREVER Technology)
The BLUE FOREVER electric resistance and internal tank feature a special surface treatment designed to significantly reduce the buildup of limescale. While this technology minimizes maintenance, periodic inspection is still recommended, especially in areas with hard water.
5.2 General Cleaning
- Clean the exterior of the water heater with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Ensure that the area around the water heater is kept clean and free from obstructions.
5.3 Periodic Inspection
It is recommended to have a qualified technician inspect the water heater annually. This inspection should include:
- Checking the pressure relief valve for proper operation.
- Inspecting electrical connections for tightness and corrosion.
- Checking for any signs of leaks or corrosion on the tank and pipes.
- Draining and flushing the tank to remove sediment, if necessary (even with scale reduction technology, some sediment may accumulate over time).
6. Troubleshooting
