Check the power plug and the power socket as often as possible.
Electrical contact must be secured and also must be provided
proper grounding The power plug and the power socket must not
heat excessively.
If the water heater is not used for a long time, especially in regions
with low air temperature (below 0
o
C), it is necessary to drain the
water from the heating tank to prevent damage of the water heater
due to the water-freezing in the internal tank. Refer to the
“Important Safety Information” part in this manual book for the
method of draining away the water from the internal tank
To make the water heater operation durable, it is recommended to
regularly clean the internal tank and remove deposits in the heating
element of the water heater. Also, check the condition of the
magnesium anode (whether fully decomposed or not), and if
necessary, replace it with a new one in case of full decomposition.
Tank cleaning frequency depends on the hardness of the water in
each location where this water heater is applied. Cleaning must be
performed by
MODENA
or special maintenance services.
The water heater is equipped with a thermal switch, which cuts off
the power supply of the heating element upon overheating or the
absence of water in the tank. If the water heater is connected to
the power supply (electricity), but the water is not heated and the
indicator does not light up, then the thermal switch was off or not
switched on. To reset the water heater to the normal operating
condition, it is necessary to:
1.
De-energize the water heater. Remove the plate of the front
cover (upside).
2.
Press the button that is located at the center of the thermal
switch, (see Picture 17).
PART 5: MAINTENANCE
WARNING!
Do cut off the power supply before do the water heater
maintenance to avoid the danger of electric shock.
