4. Configurazione e installazione
The Thermex ER80V Combi water heater is designed for vertical wall mounting. Wall anchors are not included and must be sourced separately.
4.1 Disimballaggio
Carefully remove the water heater from its packaging. Inspect for any damage during transit. The package includes the water heater unit, a 3-way safety valve (pressure reducing, non-return, and purge valve combined), and a power cable.
4.2 Montaggio
- Choose a suitable vertical wall location capable of supporting the full weight of the water heater when filled (approx. 80 kg + unit weight).
- Mark the drilling points for the wall anchors according to the unit's dimensions (445 x 459 x 771 mm).
- Securely mount the water heater to the wall using appropriate anchors.
4.3 Collegamenti idraulici
- Connect the cold water inlet and hot water outlet to the 1/2 inch connections on the unit.
- Install the provided 3-way safety valve on the cold water inlet. Ensure proper drainage for the purge valve.
- Connect the external heating source (e.g., central heating, solar panels) to the 1/2 inch heat exchanger connections located on the right side of the unit.
- Assicurarsi che tutti i collegamenti siano a tenuta stagna.
4.4 Collegamento elettrico
- Connect the power cable to a grounded 230V, 6 Amp fornitura elettrica.
- Ensure the electrical installation complies with all local electrical codes.
5. Istruzioni per l'uso
5.1 Avvio iniziale
- Before switching on, ensure the water heater is completely filled with water. Open a hot water tap to allow air to escape until water flows steadily.
- Once filled, connect the power supply.
5.2 Regolazione della temperatura
The internal heating is controlled by a double safety thermostat and a temperature adjustment knob. Use the knob to set your desired water temperature.
5.3 Using the Heat Exchanger
The integrated heat exchanger allows the water to be heated by an external source. When the external heating system is active, the electric heating element can be switched off to save energy. This is particularly useful with solar panels during summer months.
5.4 Riscaldamento elettrico
If no external heat source is available or sufficient, the electric heating element can be activated to heat the water. The electric heating element can also be switched on and off independently.
6. Manutenzione
Una manutenzione regolare garantisce la longevità e il funzionamento efficiente dello scaldabagno.
- Anode Inspection/Replacement: The heating element is protected by an anode. This anode should be inspected annually and replaced as needed by a qualified technician to prevent corrosion.
- Controllo della valvola di sicurezza: Periodically check the 3-way safety valve for proper operation. Follow the manufacturer's instructions for testing.
- Pulizia: Pulire l'esterno dell'unità con adamp panno. Non usare detergenti abrasivi.
- Decalcificazione: In areas with hard water, descaling of the tank and heating elements may be required periodically. This should be performed by a qualified professional.
7. Risoluzione Dei Problemi
| Problema | Possibile causa | Soluzione |
|---|---|---|
| No hot water (electric heating) | No power supply; thermostat set too low; heating element failure. | Check power connection and circuit breaker; adjust thermostat; contact service for element replacement. |
| Acqua non abbastanza calda | Thermostat set too low; insufficient external heat source; sediment buildup. | Increase thermostat setting; check external heating system; consider descaling. |
| Water leaking from safety valve | Normal operation due to thermal expansion; excessive water pressure; faulty valve. | Ensure proper drainage; check incoming water pressure (max 8 Bar); replace valve if faulty. |
| Rumori insoliti | Sediment buildup in tank; loose components. | Contact service for descaling; inspect for loose parts. |
For issues not listed or if solutions do not resolve the problem, please contact qualified service personnel.
