3.3 Plumbing Connections
- Connect the cold water supply to the inlet port and the hot water outlet to the fixture. Use the provided sealing washers to ensure leak-free connections.
- A pressure relief valve is typically required for water heater installations. While the product description mentions one is included, the connection point on the unit may not be explicitly marked. Consult a professional plumber for proper installation of the pressure relief valve, usually on the inlet side.
- Ensure all connections are tight but do not overtighten.
- After plumbing connections are complete, slowly open the cold water supply valve to fill the tank. Open a hot water faucet at the connected fixture to allow air to escape until a steady stream of water flows. Close the hot water faucet.
3.4 Electrical Connection
- Ensure the unit is properly grounded.
- Plug the water heater into a dedicated 110V, 1500W grounded electrical outlet.
- Do not use extension cords or adapters.
4. Operating Instructions
4.1 Powering On
- Once the tank is filled with water and electrical connections are secure, plug in the unit. The LED display will illuminate.
4.2 Setting Water Temperature
- Rotate the knob on the front panel to adjust the desired water temperature. The temperature range is 77°F - 176°F (25°C - 80°C).
- The LED display will show the current water temperature. Note that the display may show Celsius.
- Allow time for the water to heat to the set temperature. The unit will indicate when it is heating or ready.
4.3 Energy Saving Mode
- When the water temperature inside the tank falls below 77°F (25°C), the water heater will automatically enter standby mode to conserve energy. It will reactivate to heat water when needed or when the temperature drops further.
5. Maintenance
Regular maintenance helps ensure the longevity and efficient operation of your water heater.
- Exterior Cleaning: Clean the exterior of the unit with a soft, damp cloth. Do not use abrasive cleaners or solvents.
