After the correct installation of the water heater, connect the water source and power supply. When the liquid level control system senses that the water level has not reached the lower level (safe heating liquid level), the electromagnetic valve should be connected first, and the water heater should be initially filled with water. At this moment, the temperature displays the inlet water temperature. The water level indicator light and heating indicator light are not on;

When the water level reaches the lower level (safe heating level), the control panel disconnects the solenoid valve, pauses water intake, and connects the heating system. At this moment, the water level indicator light is flashing, the heating indicator light is on, preliminary heating, and intermittent water replenishment.

After reaching the set inlet water temperature, the system will inlet water again and continue heating together; The amount of water entering each time is about 2 liters (depending on different models and water temperatures);

Feed water again and heat until it reaches the upper liquid level, the water level indicator light remains on, and the water replenishment is interrupted& Nbsp; Continue heating until the temperature reaches the set temperature, and the heating indicator light goes out.

2. The primary technologies adopted are as follows:

Multi gear heating technology: The application of advanced instant heating technology and intermittent "multi gear" heating technology can meet the demand for continuous water lifting in an instant, and together, it becomes more energy-efficient and energy-saving;

Steam preheating technology: Boiling causes the remaining steam to be directed into a high water level cold water pipe to preheat the cold water, which is energy-saving and avoids the negative effects caused by the remaining steam filling the surrounding environment.
