WARNING: follow the instructions of the boat engine manufacturer on how to connect engine cooling
liquid to the heat exchanger.
• Fit the stub pipe (6) to the relief valve (4) using the hose clamp (5).
Fit the pipe so as to allow any possible water leak not to cause damage to parts of the boat.
• Open up hot water taps of the washbasins and start the water pump. This allows water to fill the water heater
and force air out of the water heater and pipes. Close taps as soon as air free water comes out of the taps.
• Check that there are no leaks on pipe joints.
UNIT POWER SUPPLY
The unit is provided with power supply cable for AC current. See fig. 3 for the connection. Make sure the water
heater operating voltage is the same as that provided by AC network.
A double pole switch has to be included on the electric installation in order to turn on and off the unit, as well as
a fuse of suitable rating. The insulation between connection contacts of the AC network must be at least 3 mm
(1/8"). The connections to AC network must be done following the National Specifications on electrical installa-
tions.
WARNING: before carrying out the connection make sure the cables are not live.
WARNING: in case the power supply cable is damaged, ensure it is replaced by a Quick service center. In
order to avoid accidents, the equipment has to be opened by authorized personnel only. If opened by an
unauthorized person, the warranty is considered void.
WARNING: never activate the heating element unless the boiler is fully filled with water or the heating
element will be permanently damaged and the protection devices (double thermostat) will fail.
WARNING: never install the boiler in closed or not well ventilated rooms.
WARNING: never install the boiler in a room filled with gas or in potentially inflammable rooms.
