We thank you for the confidence you have shown in us, by purchasing the PAGURO
for fitting in your boat.
The target of our design, to achieve a diesel unit with the power usually supplied in a
small flat, in a compact size and light weight, is completely reached. So there is not the need
to waste a large room in your boat, and even if the chosen place is away from the centerline of
the boat, the reduced weight of the PAGURO will not influence the stability.

WHERE TO FIT YOUR PAGURO
For a correct air replacement
Around the PAGURO have at least the shown tolerance; of course the ambient have
to be naturally vented with more then one external connection.
For fixing the PAGURO on board
A metallic, wooden or fiberglass structure have to be achieved. It must be as small as
possible to avoid the generation of vibrations and must keep the unit horizontally.

5
If the vibration-dampening mounts furnished with the generator are not adequate to
muffle vibration or resonance in an installation where the mounting surface is not ideal, then
adding a plate between the generator and the boat's mounting platform is a possible solution.
This will also improve the sound insulation. For this plate, use 3 cm thick wood that weighs
10-15 Kg, and soft mounts that are rectangular. Position these mounts so they are on the
diagonal and not aligned with the generator's mounts (see illustration). The generator's mounts
may be turned in any direction. Mount the plate to the boat's platform, then mount the
generator to the plate
EXTERNAL CONNECTIONS

6
Note: The internal diameter of the pipes have to be respected to avoid untightening and
leakage, but the external diameter is important too, because the correct size avoids a
noise way-out from the sound-proof capsule.
Exhaust line (on request)
STANDARD SYSTEM: the best dumping result is obtained fitting the 3 typical
"Vetus" exhaust mufflers:
the first as water lock avoids the risk of water return into the engine and dumps 50% of noise
so it must be installed; the second reduces a further 20% noise and must be fitted with a
gradient towards the out let in order to avoid water return; the third dumps a further 10% and
avoids the risk of external seawater due to waves.
IMPROVED SYSTEM: a further improvement in the noise dampening is achieved
fitting instead of the third muffler the water separator. The cooling water is separately throw
from a separate hole flowing smoothly, avoiding the noise produced by the water coming
alternatively spread from the exhaust pipe.

7
Cooling water intake (on request)
Note 1: The unit can be installed completely below the sea level; in this case the safety
cooling vacuum valve has to be fitted out of the capsule and connected with
separate pipes to the delivery of cooling pump.
Note 2: In case the hole in the hull for the water intake is undesired, the water line can be
connected in parallel with the water intake of the main engine. In this case a couple
of locking valves are necessary, because a failure of the main engine pump can
influence the cooling of the set and voiceovers.

8
Note 3: In case the hole in the hull for the water intake is undesired, the water line can be
connected in parallel with the water intake of the main engine. In this case a couple
of locking valves are necessary, because a failure of the main engine pump can
influence the cooling of the set and voiceovers.
Fuel oil line
It is usually employed the main fuel tank of the boat: the feeding pump driven by the
engine assure a suction from a maximal height of 1 m, no length limits.
A separate line coming from the tank avoids air bubbles troubles, but in several cases
the fuel can be taken from the pipe of the main engine: a couple of locking valve are
necessary, because a failure in the non-return valve of the feeding pump of the main engine
can influence the set and voiceovers.
Note 1: The injection pump of the PAGURO is self-bleeding, it means that in case the
engine shut-off for lack of fuel, after fuel tank filling up there is no need of
disconnecting the pipes for bleeding, because this operation is simply obtained
acting by hand on the lever of the feeding pump.
Note 2: Even if a small fuel filter is contained in the capsule, an external strainer and water
separator is suggested to delay the replacement time.

9
Starting battery connection
The PAGURO is negative grounded, and can be connected to the main board batteries
12 V or to a separate small battery 12 V of about 90 Ah; in this second case its internal
charging device takes care of feeding the battery with 8 A
Note : In case of connection to the main board batteries the 8 A are available as well, but are
irrelevant for charging them: a static high power battery charger fed by the 230 V (115
V) of the set must be installed on board (on request).
Remote control (supplied)
It allows the user to START and STOP the unit, verify if there is a cooling water or oil
pressure failure, (in that case the engine shut-off automatically and the RED LED is lighted)
and the power supplied control.
For preheating keep pushed contemporaneously the START and STOP buttons for
about 10 sec.. The GREEN LED energized means that the preheating is in progress. For
starting release the 2 pushed buttons, repushing the START only.
Note 1: The load indicator is designed to avoid overloading of the unit through feeding too
many electrical loads; it begins to show the load after the first half power supplied
and has to be considered normal when the bar is GREEN. The last RED LED
lighted means an overcharge: switch-off the exceeding load to return at normal
conditions.
Note 2: Do not forget the starter knob switched ON and the engine not running due to
aborted starting attempt (YELLOW LED flashing), the STOP button should be
pushed because on the contrary the engine shut-off valve remains energized and
takes useless power from the starting battery.
Note 3: If the YELLOW LED remains flashing when the set is running normally, it means
that the internal battery charger protection has tripped, so the starting battery is no
longer connected to it. In that condition the automatic protection shut-off system is
not operative, so do not operate the set with the YELLOW light flashing.
Reset the device by pushing the button located on the side of the GREY box fitted
on the set. The set can normally operate when the YELLOW flashing LED is OFF
and the GREEN on the opposite corner is ON.

10
Note 4: If for operator’s mistake the starting knob is pushed whilst the engine is already
running, an electrical safety device avoids the gears re-engagement, protecting the
starting motor and preventing failures.
For passing trough small holes the remote control panel cable, the disconnection must
be made panel side, opening the back cover, and not plug side, that is welded.
Main power 230 V (115 V)
As the most of the boats have installed 230 V (115 V) feeding line from the shore, it
has to be absolutely avoided that the main and the generator remain contemporaneously
connected to the boat plant.
A manual safety commutator (on request), or an automatic safety commutator (on
request) has to be provided.
Note: Both the lines or at least the generator line only, have to be protected with a magneto
thermic safety switch, fitted on the main board panel.
