5. MAINTENANCE
!
Do cut off power supply before maintenance, to avoid danger like electric shock.
●
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.
●
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.9;
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.
!
Non-professionals are not allowed to disassemble the thermal switch to reset. Please
contact prefessionals to maintain. Otherwise our company will not take responsiblity if any
quality accident happens because of this.
