• Ensure adequate clearance around the unit for maintenance and ventilation.
• The location should be protected from freezing temperatures.
• Install as close as possible to the main hot water usage points to minimize heat loss.

2. Drill holes and insert appropriate wall anchors suitable for the wall material and weight.
3. Securely attach the mounting bracket to the wall.
4. Carefully lift and hang the water heater onto the bracket, ensuring it is level and stable.

4.3. Water Connections

• Connect the cold water inlet (usually marked blue) to the main cold water supply.
• Connect the hot water outlet (usually marked red) to the household hot water distribution system.
• Install a pressure relief valve (PRV) on the cold water inlet line, as required by local codes.
• Ensure all connections are watertight using appropriate sealing materials.
• Open the cold water supply valve and allow the tank to fill completely. Open a hot water faucet in your home to purge air from the system until water flows steadily.
• Check for any leaks at all connection points.

4.4. Electrical Connection

• Ensure the power supply is turned off at the main circuit breaker before making any electrical connections.
• Connect the water heater to a dedicated, properly grounded electrical circuit with appropriate voltage and amperage (1500W).
• Follow the wiring diagram provided with the appliance or consult a qualified electrician.
• Once connections are secure, turn on the power supply.

5. Operating Instructions

After successful installation and filling the tank with water, you can begin operating your water heater.

5.1. Powering On/Off

• To power on the unit, ensure the main electrical supply to the water heater is switched on. The digital display should illuminate.
• To power off, switch off the main electrical supply to the water heater.

5.2. Setting Temperature

• The digital display shows the current water temperature inside the tank.
• Use the control buttons (usually '+' and '-' or similar icons) on the display panel to adjust the desired water temperature.
• The heater will automatically activate to heat the water to the set temperature and maintain it.
• For energy efficiency and safety, it is recommended to set the temperature between 45°C and 55°C. Temperatures above 60°C can cause scalding.
