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°C), 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.

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 supply socket, the two indicator lights will light up this time.
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
heating.
