-
Rotate the knob according to the marking on the knob to increase or decrease the setting
temperature.
-
The green “Power” LED and red “Heating” LED remain ON while there is power to the system.
The red LED will turns off when the water temperature reaches the user setting, at the end of the
heating phase
-
The water heater needs to be turn on for a certain period of time to reach the acceptable
temperature.
-
During the heating process, it’s normal to see slight drip at the safety valve. Please do not cover u
the safety valve outlet hole.
-
Connect this outlet hole to a discharge pipe. Water may drip from the discharge pipe of the safety
valve; therefore this pipe must be exposed to the atmosphere.
-
The safety valve is to be operated regularly (preferably at least every six months) to remove lime
deposit and to ensure that it is not blocked.

5.1 Maintenance
Warning: Do cut off power supply before maintenance, to avoid danger like electric shock.
Check the power plug and outlet as often as possible. Secure electrical contact and also proper
grounding must be provided. The plug and outlet must not heat excessively.
If the heater is not used for a long time, especially in regions with low air temperature(below 0
o
C),
it is necessary to drain water from the heater to prevent damage of the water heater, due to water
freezing in the internal tank.(Refer Cautions in this manual for the method to drain away the water
from the inner container).
To ensure long reliable water heater operation, 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
condition (fully decomposed or not) of the magnesium anode and, if necessary, replace it with a
new one in case of full decomposition. Tank cleaning frequency depends on hardness of water
located in this territory. Cleaning must be performed by MODENA or special maintenance
services.
The water heater is equipped with a thermal switch, which cuts off power supply of the heating
element upon water overheating or its absence in the water heater. If the water heater is
connected to the mains, but water is not heated and the indicator doesn’t 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, located at the center of the thermal switch, see Diagram 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.
