The appliance is equipped with an electrical cable H05RR-F 3x0.75 mm² having an
•
European plug. It is a type "Y" connection and therefore any replacement of the cable
must be carried out by a qualified staff only. Feeding 1N 230V AC 50Hz. The electrical
cable should be disposed in such a way to avoid any contact with hot and sharp parts.
The appliance should be connected with a grounding system.

CONNECTION TO THE HEATING PLANT
It's advisable to read, follow and respect what indicated in the Section Installation.
•
• Do not use the appliance, if it has not been connected to a heating plant in working
conditions.
Before setting at work the appliance, it is necessary to fill the boiler and to eliminate
•
possible air bubbles.
The appliance is equipped with a closed 8 lit expansion tank. The installer must
•
ABSOLUTELY verify the dimensions of the heating plant and, if necessary, replace the
expansion tank with another if the equipped one should not be sufficient.
The appliance is produced with the internal working at closed expansion tank. In case the
•
appliance is used in pairing with other types of appliances or heating plants, the installer
should prearrange all necessary to solve compatibility problems.
• For the equipped appliances of fast sanitary water(mod. 740-740ECO) is lively advised
the installation of a water softener (also according to the hardness of water system), to
avoid limestone coking in the rapid exchanger that in the long time reduce strongly the
efficiency and therefore the ability to produce warm water.
• The installation water should have some chemical and physical characteristics for a good
functioning of the equipment for a long time. The feeding water of bad quality could
cause problems as incrustations of the thermic exchange surfaces and sometimes the
corrosion of water surfaces of the complete circuit. The presence of chalky incrustation
penalize a lot the thermic exchange and dangerous overheating could be caused. Here
follow some examples to make treatment for water : Water hardnes > di 20°f ;
Heating plan with open expansion tank; Frequent water introduction due to lacks
or maintenance operation.
• Call a qualify company for the water treatment of thermic plan.
The equipment is supplied by a new generation Circulator ERP. For safe
•
installation and right equipment functioning, we recommend installing a Dirt
Separator with Magnet positioned on the return of the installation, upstream of the
circulator apparatus. The lack of an adequate system of filtering, could compromise
the circulator and / or its operation.
