•For the correct operation of this appliance (water heater), it is
necessary to pay attention that the maximum inlet water pressure
is 0.8 MPa (0.8 Bar).
•If the power cord is damaged, it must be replaced by the
manufacturer or qualified technicians to avoid hazard. Contact
MODENA Customer Care for repair.
•The pressure relief valve must be operated and checked regularly
to remove limestone deposits and to ensure that it is not blocked.
•In order to avoid hazard due to inadvertent resetting of thermal
cut-off, this water heater must not be supplied through external
switching device, such as timer or connected to the circuit that is
regularly switch on and off by the utility.
•This water heater (appliance) cannot be used persons with special
needs for their physical, sensory or mental capabilities, or with lack
of experience and knowledge (including children). Unless, they
have been given supervision and instruction concerning the use of
the appliance in a state way and understand the hazard that will
involve. Children should not play with the appliance. Cleaning and
user maintenance should not be performed by children without
supervision.
•The electrical storage water heater must be installed with mono-
directional safety valve in the inlet pipe. When the tank pressure is
over than 0.8 MPa, it will automatically activate the safety valve,
and water will flow out from the drainage pipe. In any condition, the
outlet valve must not be blocked. If there is a need to empty the
water in the tank, close the main water supply first. Remove the
fixing screw nail on the safety valve, and then lift the plastic handle
up to let the water flow out naturally. See the picture below.

Installation Instruction
The installation for the plumbing and the electrical wiring must be
done by qualified technicians, according to the installation
instructions and in compliance to the local authority regulations.
This water heater must be installed as near as possible to the
usage stand-point to reduce the heat loss along the pipes. To
facilitate maintenance process, make 50 cm distance for the easy-
access of the electrical parts.
This water heater should be installed on a solid cement wall and
close to the power and the water source.
Use only the accessories provided in the wrapping box to install
this electric storage water heater.
Before determining the bolt holes position, ensure that the water
heater position is more than 200 mm from the floor or ceiling board
in order to facilitate maintenance process when necessary.
After selecting the proper position of installation, use the anchor
bolt to secure the hanging board firmly (see the picture below),
and then install the appliance.
MODENA is not responsible for any improper installation and
incorrect operation of this appliance due to the failure of user in
following the instructions in this manual book.
NOTE
The button functions on the remote control are same as on the
water heater.
PART 3: INSTALLATION

6
Plumbing Connection
All piping parts should use G1/2” standard. Wind some white
sealing tape to the thread sector of the inlet pipe (marked with
blue).
Install the safety valve to the inlet pipe and then connect it to the
cold water pipe supply line.
Install a drainage pipe to the safety valve to drain away waste
water.
Install the drainage pipe in continuously downward direction and in
a frost-free environment.
Connect the hot water pipe (marked with red) to the outlet pipe.

with the set temperature at the required time.
•Wi-Fi Controller: users can install the customized Apps (IOS or
Android version) on smart-phone; connect to Wi-Fi or cellular data
(3G/4G) to control the water heater.
•Remote control configuration: turn on the water heater within 15s;

General Instruction
•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 oC), 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.
PART 5: MAINTENANCE
WARNING!
Do cut off the power supply before do the water heater
maintenance to avoid the danger of electric shock.

•To ensure the durable operation of water heater, it is
recommended to regularly clean the internal tank and remove the
deposits in the electric heating element. Also, check the condition
of the magnesium anode (whether it is 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 the usage location. Cleaning must be performed by
MODENA technicians or authorized maintenance services.
•This water heater is equipped with a thermal switch, which cuts off
the power supply of the heating element if the water is overheating
or no water in the heating element. If the water heater has been
connected to the power (electricity) source but the water is not
heated and the indicator does not light up, then the thermal switch
is “OFF”. 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 the picture below);
3. If the button is not pressed and there is no clicking, then you
should wait until the thermal switch cools down to the default
temperature.
WARNING!
Non-professionals technicians are not allowed to disassemble the
thermal switch to reset. Please contact MODENA professionals for
the appliance maintenance. Otherwise, MODENA will not take
responsibility if any accident happens because of the failed
maintenance procedure

Tank Cleaning
After having been used in a long time, the tank of the water heater will
have the dirt in it and therefore must be cleaned according to these
steps:
1. Turn off the power supply.
2. Close the cold water valve.
3. Open the hot water valve.
4. Open the pressure relief valve (if used).
5. Flush / rinse the tank with cold water.
6. Repeat this process several times until the tank is completely
clean.
Savety Valve Cleaning
Safety valves should be cleaned regularly to prevent any dirt that clogs
the valve:
1. Remove the safety valve, then clean and wash it.
2. Check if the parts of the valve are still able to move well.
3. After cleaning the valve, install the safety valve back to its position
by first giving the seal tape around the end of valve.
4. Fill the water heater with water after the pipes are refitted.
Magnesium Anode
Magnesium Anodes functions to neutralize the corrosive substances in
the water and will run out in a certain time depending on the corrosive
properties of the water. If the water has good enough quality,
magnesium anode should be replaced within 2 (two) years. If the water
quality is not good, magnesium anodes should be replaced 1 (one)
year. To replace the magnesium anodes, contact MODENA Customer
Care.
Heating Element
If the water contains lime (mud), the heating element cannot function
properly (slow heat) because it was covered by a crust of lime (mud).
Therefore, the heating element must be cleaned of each year.
Contact MODENA Customer Care for cleaning.
