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 devices.
• Installation has to be done by a qualified person, who
is responsible for the application of safety regulations in
force. Improper installation, caused by the non-
compliance 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.
• To get the best performance from the water heater and
for warranty purposes, comply strictly with the
instructions given here below.

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 (fig. 4-1): 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 (fig. 4-2) : 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).
• Electrical heater element (fig. 4-3): the appliance is
equipped with an electrical heater element at 1200W-
120V~ o 500W-120V~ in order to heat water even when
the boat engine is off (for example when the boat is in
the dock). Material : corrosion resistant alloy INCOLOY.
5. SAFETY AND CONTROL DEVICES
• Pressure relief and non-return valve (fig. 5-1): it is a
non-return valve, preventing hot water backflow into the
cold water supply; it is also a pressure relief valve,
protecting the tank against possible excessive pressure
caused by water while heating. The water is discharged
from a suitable drain, which the valve is equipped with.
