3.3 Water Connection
- Connect the cold water inlet to the designated port (usually marked blue or with a 'C').
- Connect the hot water outlet to the designated port (usually marked red or with an 'H').
- Install a pressure relief valve on the cold water inlet line, as required by local codes.
- Ensure all connections are watertight.
- Before powering on, fill the tank completely with water by opening a hot water tap until water flows freely, indicating the tank is full and air has been purged.
3.4 Electrical Connection
- The water heater operates on a cable electric power type and requires a 3000 Watt supply.
- Connect the appliance to a dedicated electrical circuit with appropriate overcurrent protection (circuit breaker).
- Ensure proper grounding according to electrical codes.
- All electrical connections must be made by a qualified electrician.
4. Operating Instructions
4.1 Initial Start-up
- After ensuring the tank is full of water and all connections are secure, restore power to the unit.
- The water heater will begin heating the water to the set temperature.
4.2 Temperature Control
The water heater is equipped with a thermostat to control the water temperature. The declared thermostat setting is 60°C. Refer to the control panel on your specific unit for instructions on adjusting the temperature. Higher temperatures consume more energy and increase the risk of scalding.
5. Maintenance
Regular maintenance ensures the longevity and efficient operation of your water heater. Always disconnect power before performing any maintenance.
5.1 Annual Inspection
- Have a qualified technician inspect the pressure relief valve, heating element, and anode rod (if applicable) annually.
- Check for any signs of leaks around connections or the tank.
5.2 Descaling
In areas with hard water, mineral deposits (scale) can accumulate on the heating element and inside the tank, reducing efficiency. Descaling should be performed periodically by a qualified technician.
5.3 Cleaning
Clean the exterior of the water heater with a soft, damp cloth. Do not use abrasive cleaners or solvents.
6. Troubleshooting
