1. GENERAL PRECAUTION MEASURES
The following instructions are important to grant safe
installation, use and maintenance of the appliance.
• This booklet is integral and essential part of the water
heater: therefore it has to be kept handy for any further
consultation.
• The water heater has been manufactured for hot water
production: any other use of it has to be considered
dangerous and unsuitable.
• The appliance is not to be installed in damp rooms,
bathtubs, washbasins, showers, pools etc. and it has
to be protected from water splashes, water spouts or other
liquids in order to avoid short circuiting the electrical

with the instructions provided by the manufacturer, could
cause injury to people, animal or damages to other
equipments for which the manufacturer accepts no
responsibility.
• Before plugging in the water heater, make sure that the
electrical features printed on the data badge correspond
to those of the electrical supply.
• If the water heater is installed in a bathroom, in a damp
room or close to water, take care of the safety distances
as per CEI-CEE regulations. Furthermore, switches or any
other electrical control shall not be reachable by anyone
having a shower or using the bath. Do not touch the
appliance with wet or damp hands.
• Do not allow any usage by children or incapacitated
people without any supervision.
• Packaging parts (plastic bags, polystyrene, clips, etc.)
have to be kept away from children, because they can
be dangerous.
• Read carefully this booklet because it provides useful
instructions concerning safety, installation, use and
maintenance.
• If the appliance is sold or moved to another owner, make
sure that this booklet stays with the appliance, so the new
owner and/or installer can consult it.
• To avoid the risk of damage due to frost, if the appliance
is not used for a long period and it is installed in a non-
heated room, we advise to empty it completely. The
manufacturer is not responsible for any damage or
breakage due to frost or to water leakage from the plant.

3. PACKAGING CONTENT
The water heater is packaged and delivered in a cardboard
box with appropriate protection. Apart from the unit, inside
the box there is the installation manual.
4. CONSTRUCTION AND OPERATION DESCRIPTION
The purpose of this appliance is to heat domestic hot water
in two different ways:
1. By the heat exchange between the engine cooling water
and the water stored inside the tank. This heat exchange
is possible thanks to a heat exchanger. The engine
cooling water circulates through a coil placed at the
centre of the tank in order to spread heat uniformly.
2. By means of an electrical heater element (standard
supplied with the appliance).
Main parts:
• Storage tank: it is entirely made of AISI 316L stainless
steel.
• Casing: the casing is very resistant to bumps and to any
external stress, having at the same time a very nice
design. It is made of 2 parts of black plastic and a central
part of stainless steel.
• Thermal insulation: a 2 cm thick insulation in expanded
polyurethane with closed cells avoids useless heat losses.
In this way heat loss for thermal inertia is reduced to 1° C
per hour over a period of 24 hours.
• Heat exchanger: it is made of AISI 316L stainless steel;
its exchange's surface allows to exploit at best the heat of
the engine cooling water and to get hot water even in
extreme conditions (very small temperature differences).
