Setup and Installation
The Ferroli Tiber C water heater is designed for indoor, wall-mounted installation. Professional installation is highly recommended.
Installation Steps:
- Site Selection: Choose a suitable indoor location, preferably near hot water outlets, with adequate wall strength to support the full weight of the water heater (approximately 100 kg when full). Ensure proper ventilation and accessibility for maintenance.
- Mounting: Securely mount the water heater to the wall using appropriate fasteners and brackets (not included, consult a professional for suitable hardware). Ensure the unit is level.
- Plumbing Connections: Connect the cold water inlet and hot water outlet pipes. Install a pressure relief valve on the cold water inlet line as per local codes. Ensure all connections are watertight.
- Electrical Connection: Connect the water heater to a dedicated electrical circuit with appropriate overcurrent protection. The appliance requires a 230 Volt supply. Ensure proper grounding.
- Filling the Tank: Before powering on, open a hot water tap in your home and allow the tank to fill completely with water. Once water flows steadily from the tap, close the tap. This purges air from the system.
Operating Instructions
Once installed and filled, operating your Ferroli Tiber C water heater is straightforward.
- Power On: Connect the water heater to the main power supply. The charge indicator light will illuminate, indicating that the heating element is active.
- Setting Temperature: Use the adjustable external thermostat to set your desired water temperature. Turning the knob clockwise typically increases the temperature.
- Digital Thermometer: The digital display will show the current water temperature inside the tank. This allows for precise monitoring.
- Heating Cycle: The water heater will automatically heat the water to the set temperature and then maintain it. The charge indicator light will turn off once the set temperature is reached and turn back on when heating resumes.
- Energy Saving: For optimal energy efficiency, set the temperature to a comfortable level (e.g., 50-55°C) rather than the maximum.
Maintenance
Regular maintenance ensures the longevity and efficient operation of your water heater.
- Anode Inspection: The magnesium anode protects the tank from corrosion. It should be inspected and replaced by a qualified technician every 1-2 years, or more frequently in areas with hard water.
- Draining the Tank: If the water heater will be out of use for an extended period or if there is a risk of freezing, drain the tank completely. Disconnect power, close the cold water inlet, open a hot water tap, and open the drain valve at the bottom of the tank.
- Pressure Relief Valve: Manually operate the pressure relief valve at least once a year to ensure it is not blocked. Follow manufacturer guidelines for this procedure.
- Cleaning: Clean the exterior of the water heater with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Insulation Check: Periodically check the insulation for any signs of damage or degradation.
Troubleshooting
Refer to the table below for common issues and their potential solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| No hot water | No power supply; thermostat set too low; tripped circuit breaker; faulty heating element. | Check power connection and circuit breaker; adjust thermostat; contact a qualified technician. |
| Water not hot enough | Thermostat set too low; insufficient recovery time; sediment buildup. | Increase thermostat setting; allow more time for heating; consider professional descaling. |
| Water leaking | Loose connections; faulty pressure relief valve; tank corrosion. | Tighten connections; inspect/replace pressure relief valve; contact a qualified technician for tank inspection. |
| Unusual noises | Sediment buildup in the tank. | Professional descaling may be required. |
