Check the power plug and the power socket as often as possible.
The power socket must be secured, and the proper grounding
must be provided. The power plug and the power socket must not
heat excessively.
If the water heater has not been used for a long time, especially in
the area with low air temperature (below 0
o
C), it is necessary to
drain the water from the heating tank to prevent damage, due to
frozen water 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 inner tank).
To make the water heater durable, it is recommended to regularly
clean the internal tank and remove the deposits on its heating
element. 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.
The frequency of tank cleaning depends on the hardness of the
water in each location where this water heater is applied. Cleaning
must be performed by
MODENA
or authorized maintenance
services.
This 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, 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 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 12).
PART 5: MAINTENANCE
WARNING!
Do cut off the power supply before maintenance, to avoid danger
such as electric shock.
