4.0 - Installation requirements
The water heater must be installed in a dry and well-ventilated place. This precaution is necessary, even if the
water heater is made of materials resistant to the marine environment, due to the presence of electrical devices
(in models equipped with them). In addition, installation in an unventilated place may cause condensation;
condensation may be mistaken for a false leak.
4.1 - Installation procedure
A - Apply the brackets to the tank (1).
B - Fix the water heater to a flat surface as shown in figure 1 using supports suitable for the weight of the water
heater and the type of surface available for installation.
WARNING: the weight of the water heater indicated in the technical specifications refers to empty
equipment. For the weight when fully loaded, add the weight of the mass of water filled in the
equipment to the weight when empty (1 litre of water corresponds to approximately 1 kg. / 2.2 lb).
C - Make the hydraulic connections for the tap hot water input and output and the engine cooling circuit to the heat
exchanger (in models featuring it) as shown in figure 2. The connection between the engine cooling circuit and the
water heater exchanger should be as short as possible.
WARNING: the overpressure release pipe must be positioned on a continuous downward slope and
in a place protected from ice formation.
WARNING: water may drip from the overpressure release pipe; leave this pipe open so that it can
drain the water in the atmosphere.
WARNING: use Loctite 243, 577 or Teflon when installing the fittings.
Check that there are no water leaks.
4.2 - Use
WARNING: follow the engine manufacturer's instructions to withdraw the coolant to be sent to the
water heater exchanger.
• Position the stub pipe (2) of the valve (1) securing it with the clamp (3). Position it in
such a way that any spillage of water will not damage other objects.
• Open the hot water taps of the washbasins and start the water pump. This allows
the air in the water heater and in the pipes to flow out. Close the taps as soon as only
water starts to flow out.
• Check that there is no leakage from the fittings.
4.2.0 - Power supply of the equipment
For connections to the AC network, see the wiring diagram on page 8. Before supplying power to the water heater,
make sure that its operating voltage corresponds to that supplied by the AC network.
A double pole switch must be installed in the electrical system to turn the equipment on and off and a fuse suitable
for its absorption. The insulation material between the contacts of the connections to the AC network must be at
least 3 mm. Connections to the AC network must be made in accordance with the national standards on electrical
systems.
Before connecting the equipment, make sure that cables are not live.
Never switch on the electric element if the water heater is NOT filled with water, otherwise the
heating element could be irreversibly damaged.
