LEGIONELLA BACTERIA FUNCTION 

Legionella are small rod shaped bacteria which are a natural constituent of all fresh waters. Legionaries’ disease 

is a pneumonia infection caused by inhaling of Legionella species. Long periods of water stagnation should be 

avoided; it means the water heater should be used or flushed at least weekly.
The European standard CEN/TR 16355 gives recommendations for good practice concerning the prevention of 

Legionella growth in drinking water installations but existing national regulations remain in force.
This electro-mechanical storage water heater is sold with a thermostat set at a temperature higher than 60°C; 

it means it is enabled to carry out a “thermal disinfection cycle” to restrict the Legionella growth inside the tank. 
Warning: when this software has been carrying out the thermal disinfection treatment, water temperature can 

cause burns. Feel water before bathing or showering.

INSTALLING NORMS (for the installer)

This product, excluding horizontal models (Table 1), is a device that must be installed vertically in order 

to operate correctly. Once installation is complete, and before any water is added or the power supply 

is connected, use a measuring instrument (i.e. a spirit level) to check that the device has been installed 

perfectly vertical. 

The appliance heats water to a temperature below boiling point. It must be linked up to a mains water supply ac-

cording to the appliance performance levels and capacity. Before connecting the appliance, it is first necessary to: 

-   Check whether the characteristics (please refer to the data plate) meet the customer’s requirements. 

-   Make sure the installation conforms to the IP degree (of protection against the penetration of liquids) of the 

appliance according to the applicable norms in force. 

-   Read the instructions provided on the packaging label and on the appliance data plate.

This appliance was designed to be installed only inside buildings in compliance with the applicable norms in 

force. Furthermore, installers are requested to keep to the following advice in the presence of: 

-  

Damp: do not install the appliance in closed (unventilated) and damp rooms. 

-  

Frost: do not install the appliance in areas where the temperature may drop critically and there may be a risk 

that ice may form. 

-  

Sunlight: do not expose the appliance to direct sunrays, even in the presence of windows. 

-  

Dust/vapours/gas: do not install the appliance in the presence of particularly dangerous substances such as 

acidic vapours, dust or those saturated with gas. 

-  

Electrical discharges: do not install the appliance directly on electrical supplies that aren’t protected against 

sudden voltage jumps. 

In the case of walls made of bricks or perforated blocks, partition walls featuring limited static, or masonry differ-

ent in some way from those stated, you first need to carry out a preliminary static check of the supporting system.

The wall-mounting fastening hooks must be designed to support a weight that is three times higher than the 

weight of the water heater filled with water. 

Fastening hooks with a diameter of at least 12 mm are recommended.
