Before installing this electric storage water heater, check and ensure that the
power socket is reliably grounded. Otherwise, this water heater cannot be
installed and used yet. Do not use the extension cord if the power socket is
damaged. Incorrect installation and use of this water heater may result in
serious injuries and loss of property.
Special Caution
•This appliance (water heater) is not intended to be used by persons with
special needs for their physical, sensory or mental capabilities, or lack of
experience and knowledge (including children), unless they have been given
the supervision or instructions concerning the use of the appliance by a
person who responsible for their safety. Children should be supervised to
ensure that they are not playing with this water heater.
•The wall in which this water heater is installed should be able to bear the
twice bigger load than the weight of this water heater filled fully with water
without distortion and cracks. Otherwise, other strengthening measures
should be adopted.
•The power socket must be earthed (grounded) reliably. The installation
height of the power socket should not be lower than 1.8 m. The rated current
of the socket should not be lower than 16A.
•The power socket and the power plug should be kept dry to prevent
electrical leakage. If the flexible power cord is damaged, a special power cord
that is provided by manufacturer must be selected, and replaced by professional
maintenance personnel. Contact MODENA Customer Care for help.
•For the correct operation of the appliance, it is necessary to pay attention
that the maximum inlet water pressure is 0.75 MPa, and the minimum inlet
water pressure is 0.1 MPa
•When using the water heater for the first time (or for the first use after
maintenance), the water heater cannot be switched on until it has been filled
fully with water. When filling the water, at least one of the outlet valves of
the water heater must be opened to exhaust the air. This valve can be closed
after the water heater has been filled fully with water.
•The pressure relief valve that attached with the water heater must be
installed at the cold water inlet of this water heater, and make sure it is not

exposed to the vapor. The water may be out-flowed from the pressure relief
valve, so the outlet pipe must be opened wide towards the air. In order to
drain away the water inside the tank (inner container), open up the pressure
relief valve. Twist off the thread screw of the pressure relief valve, and lift the
drain handle upwards (see picture 1). The drainage pipe that connected to
the pressure relief hole must be kept sloping downwards and placed in a
frost-free environment. The water may drip from the discharge pipe of the
pressure relief valve; therefore, this pipe must be left open to the air
(atmosphere).
•During the heating process, there may be drops of water dripping from the
pressure relief hole of the pressure relief valve, and this is a normal case. The
pressure relief hole shall not be blocked under any circumstances; otherwise,
the water heater may get damaged or even resulting on accidents. If there is
a large amount of water leak, please contact MODENA Customer Care for
repair.
•The pressure relief valve needs to be checked and cleaned regularly, to make
sure it will not be blocked.
•Since the water temperature inside the water heater can reach up to 75 °C,
the hot water must not be exposed to human bodies when it is initially used.
Adjust the water temperature suitably to the endurance of human skin to
avoid scalding.
•If any parts and components of this water heater are damaged please
contact MODENA Customer Care for repair.

English 5
Installation Instruction
•This water heater should be installed on a solid wall. If the strength of the
wall cannot bear the load equal to twice bigger of the total weight of the
water heater filled fully with water, it is then necessary to install a special
support. In case of the hollow bricks wall, ensure to fill the wall with
concrete cement completely, and use anchor fastener bolt (expansion bolt)
in case of the hebel wall.
•After selecting a proper location, determine the position of two holes that
are used for the installation of the expansion bolts with hook. Make two
holes on the wall by using a chopping bit with the depth matching to the size

of the expansion bolts that attached with the water heater. Then, insert the
bolts, turn the hook upwards, tighten the nuts to fix firmly, and then hang
the water heater on it.
•Install the power socket in the wall. The requirements for the power socket are
as follows: 250V/10A, single phase, and three electrodes. It is recommended
to place the power socket on the top right of the water heater. The height of
the socket to the ground shall not be less than 1.8 m.
•If the bathroom is too small, the water heater can be installed at another place
outside the bathroom. However, to reduce the heat loss caused by long
pipeline, the installation position should be as near as possible to the bathroom.
Plumbing Connection
•The dimension of inlet and outlet water pipe is G1/2.
•Connect the pressure relief valve with the inlet water of the water heater.

•To avoid the leakage when connecting the pipelines, the provided rubber
seal must be installed by the end of the threads to ensure the connections
are leak proof.
•If the user wants to make a multi-ways supply system, refer to the method
shown in figure below for connection of the plumbing.

•First, open the outlet valve, and then open the inlet valve. The water heater
gets filled with the water. When the water flows out of the outlet pipe, it
implies that the water heater has been filled fully with water. Then, closes
the outlet valve.
•Insert the power plug into the power socket.
•If the indicator lamp lights up, the thermostat will automatically control the
temperature. When the water temperature inside the heating tank has
reached the set temperature, the water heater will switch off automatically.
If the water temperature falls below the set point, the water heater will turn
on automatically to restore the default temperature.
•Rotate the knob according to the knob marker to increase or decrease the
temperature.
•In a power-on state, the water heater is heating when the indicator light
turns blue. The indicator light will turn off when the heating process is
finished, and the water heater is in the insulating state.
PART 4: HOW TO USE

English 9
•Check the power plug and the power socket as often as possible.
Electrical/power socket must be secured, and proper grounding must be
provided. The power plug and the power socket must not heat excessively.
•If the water heater is not used for a long time, especially in the area with
low air temperature (below 0 oC), it is necessary to drain the water from the
heater to prevent damage, due to water-freezing in its internal tank (refer to
the “Cautions” chapter in this manual book for the method of draining away
the water from the inner container/tank).
•To make the water heater durable, 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 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.
Contact MODENA Customer Care if necessary.
•The water heater is equipped with a thermal switch, which cuts off the
power supply of the heating element upon overheating water or the
absence of water in the water heater. 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 side/lower cover.
2. Press the button that is located at the center of the thermal switch.
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.
PART 5: MAINTENANCE
WARNING!
Do cut off the power supply before maintenance to avoid danger like
electric shock.
