5 Cleaning and maintenance
B
WARNING! Do cut off power supply
before maintenance, to avoid danger
like electric shock.
• Check the power plug and outlet as often as pos-
sible. 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, espe-
cially 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 Cau-
tions 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 inter-
nal 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 heat-
ing element upon water overheating or its ab-
sence 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 ther-
mal switch was switched off or not switched on.
To reset the water heater to the operating condi-
tion, 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.7;
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.

A
mal switch to reset. Please contact
professionals to maintain. Otherwise
our company will not take responsi-
bility if any quality accident happens
because of this.
