5. CONSTRUCTION DESCRIPTION AND OPERATION
The purpose of this appliance is to heat the domestic hot water in two different ways (see fig FIG_5-1):
A. through the exchange of heat between the engine cooling water and the water stored in the tank. This heat
exchange is possible thanks to a heat exchanger. The engine cooling water circulates through a coil located in
the center of the tank to spread the heat evenly.
B. by means of an electric resistance (supplied as standard with the appliance).
Main parts (see FIG_5-2.):
1. Storage tank: it is entirely made of AISI 316L stainless steel.
2. Metallic outer coating: it is very resistant to external shocks and stresses, while having a very pleasant design.
3. Thermal insulation: made of closed cell polyurethane foam, it avoids unnecessary heat loss. In this way the heat loss
due to thermal inertia is reduced to 1 ° C per hour for a period of 24 hours.
4. Heat exchanger: it is made of AISI 316L stainless steel. Its exchange surface makes it possible to make the most of
the heat from the engine cooling water and to obtain hot water even in extreme conditions (very small temperature
differences).
5. Thermostat: has two functions, namely:
a. adjustable thermostat: interrupts the power supply to the heater element when the preset temperature is
reached (the temperature can be adjusted between 13 ° C and 65 ° C, according to the user's needs).
b. safety thermostat: cuts off the power supply to the heating element when, in the event of a malfunction of the
appliance, the water temperature reaches 83°C. Manual intervention is required to restart the appliance
(manual reset).
Temperature range: from 13 ° C to 65 ° C
Safety temperature: 83 ° C
Maximum current:
16 A
6. Electric heater: the appliance is equipped with an electric heating element (550/1250W, 230V ~) to heat the water
even when the boat's engine is off (for example when the boat is at a wharf). Material: corrosion resistant INCOLOY
alloy.
7. Drain valve
8. Cold water inlet and safety and non-return valve: prevents hot water from flowing back into the cold water inlet pipe. It
is also an overpressure safety valve: it protects the tank from possible excessive pressures caused by the expansion
of the water during heating. The water is discharged through the drain with which the valve is equipped. Calibration:
800 ± 50 kPa (116 ± 7 psi)
9. Hot water outlet
10. Plastic outer coating
6. INSTALLATION INSTRUCTIONS
•
The installation must be carried out, in accordance with current legislation, by a qualified person who will perform not
only a correct set up of the appliance, but also the necessary tests before starting the water heating.
