blocked; otherwise, the water heater may be damaged, even
resulting on accidents.
The drainage pipe connected to the pressure relief hole must be
kept sloping downwards.
Since the water temperature inside the tank can reach up to 75
o
C,
the hot water must not be directly flowed to human skin at the
initial use. Adjust the water temperature to a suitable temperature
to avoid scalding.
If the flexible power supply cord is damaged, the special supply
cord provided by
MODENA
must be selected, and replaced by
MODENA
maintenance personnel (technician).
If any parts and components of this water heater are damaged
please contact
MODENA
Customer Care for repair.
For the correct operation of the water heater, it is necessary to pay
attention that the maximum inlet water pressure is 0.8 MPa (0.8
Bar), and the minimum inlet water pressure is 0.015 MPa (0.15 Bar).
When the water pressure is over 0.8 MPa, the safety valve will
automatically active. The water may drip from the drainage pipe of
the pressure-relief device (Picture 2). Therefore, this pipe must be
left open towards the air (atmosphere). The pressure-relief device
should be operated/activated regularly to remove limestone
deposits and to ensure that the pipe is free from blockage;
Draining away the water inside the inner container can be done
from the pressure relief/safety valve. Twist off the fixed screw nail
of the safety valve, and lift the handle for water drainage upwards
(Picture 3). A drainage pipe connected to the pressure relief device
has to be installed in a continuously downward direction and in a
frost-free environment.
CAUTION!
In order to avoid a hazard due to inadvertent resetting of the
thermal cut-out, this appliance must not be supplied through an
external switching device, such as a timer, or connected to a
circuit that is regularly switched on and off by the utility.
