4. METHODS OF USING
NOTE
During normal operation, the inlet valve shall be always kept open.
First, 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.
Insert the supply plug into the socket
.
●
Rotate the temperature adjusting knob, the “HEATING” indicator will light up. According to the
marking on the knob to increase or decrease the setting temperature
.
The thermostat will
automatically control the temperature. When the water temperature inside the heater has
reached the set temperature, it will switch off automatically and light off the “Heating” indicator.
When the water temperature falls below the set point, the heater will be turned on automatically
to restore the heating, the indicator will light up again.
Check the power plug and outlet as often as possible. Secure electrical contact and also proper
grounding must be provided. The plug and outlet must not heat excessively.
If the heater is not used for a long time, especially in regions with low air temperature(below 0
℃
),
it is nessary to drain water from the heater to prevent damage of the water heater, due to water
freezing in the internal tank.(Refer Cautions in this manual for the method to drain away the water
from the inner container).
To ensure long reliable water heater operation, it is recommended to regularly clean the internal
tank and remove deposits on the electric heating element of the water heater, as well as check
condition (fully decomposed or not) of the magnesium anode and, if necessary, replace it with a
new one in case of full decomposition.Tank cleaning frequency depends on hardness of water
located in this territory. Cleaning must be performed by special maintenance services. You can
ask the seller for address of the nearest service center.

5. MAINTENANCE
WARNING
Before doing any maintenance, please cut off the power supply.
!
The water heater is equipped with a thermal switch, which cuts off power supply of the heating element
upon water overheating or its absence in the water heater. If the water heater is connected to the mains,
but water is not heated and the indicator doesn’t light up, then the thermal switch was switched off or not
switched on. To reset the water heater to the operating condition, it is necessary to:
1. De-energize the water heater, remove the plate of the side/lower cover.
2. Press the button, located at the center of the thermal switch, see Fig.6;
3. If the button is not pressed and there is no clicking, then you should wait until the thermal switch
cools down to the initial temperature.
