Operating Procedure
Check all the piping connection to avoid the leakage case before turning on this electric storage
water heater.
Open one of the outlet valves of the water heater, then, open the inlet valve .to get the water
heater filled with water.
When the water flows out of the outlet pipe it implies that the heater has been filled fully with
water, and the outlet valve can be closed. .
Make sure that the tank is fully filled up with water; otherwise it will cause the heating elements to
be damaged. Note: During normal operation, the inlet valve shall be always kept open.
Insert the power plug into the power socket and check the reliability of the leakage protection
device (ELCB). Press the testing button, the indicator light on the power plug should be off, and
the reset button should bounce up; then push down the reset button, the indicator light will turns
on to verify that the leakage protection works well (Picture 11). If the reset button cannot be
pressed during the process of using, the leakage protection device (ELCB) might be error or fails
to work; If the reset button is pressed down and bounce up again, then it shows the power circuit
leaks or the power supply is disconnected.
If the indicator lights up, the thermostat will automatically control the temperature. When the water
temperature inside the heater has reached the set point, it will switch off this water heater
automatically. When the water temperature falls below the set point, the heater will be turned on
automatically to restore the heating.
Operating of the Water Heater
Rotate the knob according to the marking (indicator) to increase or decrease the temperature
setting.
Rotate the power adjustment knob to the position I, II, or III, and the water heating process starts.
The water heater needs to be turned on for a certain period of time to reach the desired (set)
temperature.
During the heating process, it is normal to see the slight drip at the safety valve. Please do not
cover the hole of the safety valve outlet.
Connect this outlet hole to a discharge pipe. The water may drip from the discharge pipe of the
safety valve; therefore this pipe must be exposed to the atmosphere.
The safety valve has to be operated regularly (preferably at least every six months) to remove the
limestone deposit and to ensure that it is not blocked.

Heating function: within 30oC to 75oC to set the heating temperature.
Safety function: with anti-dry protection, overheat protection to keep safe when using.
Product Features
Super tank (Single Weld Line) with Titanium Porcelain Enamel coating which is rut-proof, erosion-
proof, higher efficiency and having a longer life span.
Energy saving with minimum heat loss. The water temperature is able to be maintained up to 48
hours after the electricity is switched off.
Warning: Do cut off the power supply before maintenance, to avoid danger like electric shock.
Check the power plug and the power socket as often as possible. Secure electrical contact and
also proper grounding must be provided. The power plug and the power socket must not heat
excessively.
If the heater is not used for a long time, especially in the area with low air temperature (below
0oC), it is necessary to drain the water from the heater to prevent damage of the water heater,
due to water-freezing in the internal tank.(Refer to the “Cautions” chapter in this manual book for
the method of draining away the water from the inner container).
To make the water heater operation 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.
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 switched 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 13;
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.
Warning: Non-professionals are not allowed to disassemble the thermal switch to do the reset.
Please contact professionals of MODENA to maintain this electric storage water heater.
Otherwise, MODENA will not take responsibility of any accidents.

Check if the parts of the valve are still able to move well.
After cleaning, replace the safety valve in its place by giving the seal tape.
Fill the water heater with water after pipes refitted.
Magnesium Anode
Magnesium Anodes serves to neutralize 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 (PAM),
Magnesium Anodes should be replaced within 2 (two) years. If the water quality is not good,
Magnesium Anodes should be replaced in maximum 1 (one) year period of time. To replace
Magnesium Anodes, contact MODENA Call Center.
Heating Element
If the water contains limestone (Mud), the heating element cannot function properly (slow heat)
because it was covered by a crust of limestone (mud). Therefore, heating element must be cleaned
off from the sediment each year. To do this cleaning procedure, contact MODENA Call Center.
