Check all the piping connection for leakage before turning on the electric power of the heater.
Open any one of the outlet valves at the outlet of the water heater, then, open the inlet valve.
The water heater gets filled with water. When water flows out of the outlet pipe it implies that the
heater has been filled fully with water, and the outlet valve can be closed.
Make sure that the tank is fully filled up with water; otherwise it will cause the heating elements to
be damaged.

pressed, it shows the leakage protection device fails; If the reset button is pressed down and
bounce up again, then it shows the circuit leaks or power supply fails.
If the indicator lights up, the thermostat will automatically control the temperature. When the water
temperature inside the heater has reached the set temperature, it will switch off automatically, when
the water temperature falls below the set point the heater will be turned on automatically to restore the
