1 GENERAL INFORMATIONS
1.1CONFORM USE
The generator is suitable for independent productionof electrical energy withinthe voltage and wattage limits
declared by the manufacturer.
Any other use outside the already stated fieldof use is prohibited: the generator is intended for marine use.
The generator has been designed to operate independently (without operator) if not for sporadic checks.
The limits of use are:
- operatingtemperature: -10°C (14°F), +40°C (104°F)
- relative humidity: 30% - 90%
- the generator is suitable for marine operation.
Installations are subjectto approvalby manufacturer orby anauthorisedinstaller.
Arbitrary modifications to the machine are prohibitedfor safety reasons.
Original spare parts must be used on pain of losingmachine conformity.
Allthe operations that require dismantling of specialparts may only be carried out by technicians authorised by
the local dealer or the manufacturer.
Only manufacturer techniciansor personneltrained havethe necessary knowledge of the generator andthe
special equipmentas wellas the experience to carry out anyoperation inthemost economical andreliable way.
1.2 RESIDUAL RISKS
The generator has been designedtakinginto account the safety regulations set out in the EC directives and
standards; nonetheless, the followingresidual risks remain:
- injury caused by contact with hot parts during maintenance.
- injury caused by electrocution during maintenance on the electric panel.
- risks connected with long periods of exposure to the noise of the generator (with opencowling).
- risks due to contact with the generator lubricants during maintenance.
- risks due to the fire hazard the fuel represents.
Because of the typical intrinsic danger of the Generators, youare reminded that, although the generator has
beendesigned, constructed andtestedin accordance with the safety regulations, only proper andcarefuluse
can guarantee full safety; to this end, the various precautions to be takenduringuse of the Generator are
listedbelow.

BATTERY
Do not touch the electrolitic battery acid
Sufficient ventilation of the battery area.
• Keepthe area around the battery wellventilated, paying attention to keep
sparks, open flame and any other formof ignition away. Duringengine running or
chargingbattery, hydrogengas is produced fromthe battery and
can be easily ignited.
Battery acid. Sulfuric acid in batteries can cause severe injury or death.
Sulfuric acidin battery cancause permanent damage to eyes, burn, skin,and hole
in clothing.
Always wear splash-proof safety googles when workingnear the battery. If battery
acidis splashedin the eyes or skin,wash immediatelythe affectedarea with large
quantity of clean water. Seek immediate medical aid incase of eyes contact.
Do not intentionally make the battery sparkby short-circuiting to check its
remainingcharge. It will cause fires.
If the battery electrolyte frozen, recharge the battery after warming upto
thaw it.
SAFETY CLOTHING
Do not expose your skin to high pressure fuel spray
Be careful so as not to bringyour skin in contact with highpressure fuel spray
from broken fuel injection pipe to penetrate your skin to cause inflamed.
If exposing to the spray should occur, obtain prompt medical treatment.
Beware of dirt from air blowing
Wear protective equipment such as goggles to protect your eyes when
blowingcompressed air or steam. Dust or flyingdebris can hurt eyes.

(1) Limited - time running power (LTP) ISO 8528-1
It is the maximum power that, under the environment conditions established by the norm ISO 3046/1, the generator group it is able to disburse for
a maximum of 500 hours for year, of which a maximum of 300 hours among the interval of maintenance prescribed by the builder. It is accepted
the operation to this power conditions the duration of the group.
An overload of the 10% is admitted only for regulation.
(2) Prime power (PRP) ISO 8528-1
It is the available maximum power for a variable power cycle that the generator group is able to disburse for a boundless number of hours for year
among the interval of maintenance prescribed by the builder and under the environment conditions established by the norm ISO 3046/1. The middle
power during a period of 24 hours, doesn't have to exceed 80% of the PRP.

3.1 GENERATOR HOUSING CHARACTERISTICS
- The generator must be installed in a sufficiently
ventilated room able to assure the small amount of air
required for engine combustion.
-The roommust beacoustically separatedand isolated
from the living quarters.
- The generator must be positionedinsucha way as to
facilitate normalmaintenance operations.
- It is advisable to installthe generator in the
propulsion engine room provided that it meets the
above conditions.
- The air must be clean.
-The airtemperature inthe place of installation must be
between -5°C(23°F) and +40°C(104°F).
- The relative humidity must not exceed 50% at a
maximum temperature of +40°C (104°F). Relative
humidity of 90% at +20°C (68°F) and 100% at +25°C
(77°F)is permissible.
3.2 LIFTING
To lift the generator place the hook inthe hole (ref.1)
Always take these precautiona when lifting the
generator:
- Do not swing suspended loads.
- Never leave the load unattended.
- Lower the generator to the groundvery slowly.
- Always maintain the safety distance.
All the lifting operations must be carried out by
personnel specialised in this type of work, such as
truckdrivers, cranedrivers, slingers.
Theoperatorisconsideredresponsibleforusingthe
correctmachine slingingand liftingtechnique.
3.3ANCHORING THE GENERATOR
Forfixingthe generator setpredispose anadapted plinth
to sustain the weight andvibrations of the generator.
Proceed then to the perforation of the plinth following
the indications in (ref.2).
3.4 VENTILATION
Thegenerator is equippedwithan internalforced cooling
systemthrough a water/air exchanger.
The amount of air required for combustion is
aspiratedthrough the intake locatedonthebase (ref.3):
Therefore, always checkthat this intake is
free of any obstruction.

3.5 COOLING WATER CIRCUIT
The generator engine is cooled by an open-circuit
systemin whichseawater circulates.
At the time of installation, a seawater feed circuit
must be arranged for cooling, and an exhaust system
for the combustiongas and water mixture.
3.5.1 SEAWATER FEED SYSTEM
Two water intake systems are normally adopted on
boats:
-Direct intake system(ref.1).
-Systemwithbaffle (ref.2).
Manufacturer recommends using the direct intake
system (ref.1), since it prevents intake of pressurised
waterinto theintake ducts, instead generatinga vacuum
easily overcome by the water pump head of the
generator.
Do not fit any type of protection cap on the direct
intake system.
The system with baffle (ref.2), on the other hand, may
cause the following problems:
a- If mounted withthe slots facingthe bow:
In this case, during navigation and with the generator
off, pressure is created in the water intake duct, which
maycause the systemto fillupuntilreachingthe exhaust
port, thus making it possible for water to enter the
cylinders.
b- If mounted with the slots facingthe stern:
In this case, duringnavigation a vacuummay be created
in thewater intakeduct suchas to inhibitthewaterpump
to activate the cooling system or such as to limit the
flow rate withconsequentoverheatingofthe generator.

3.5.2 COMPONENTS
Ifthe generatorisinstalledat aheight over1m (3,3ft)
above the waterline, a check valve (ref.2) must be
fitted after the seawater intake to prevent the water
circuit from emptying out when the engine is off. If
the circuit is empty, the water pump impeller may
be damaged during starting.
For the same reason, when starting the generator
for the first time, manually prime the intake pipe
leading from the valve to the pump.
- 1/2"direct seawaterintake (ref.1).
- 1/2" ball cock (main system) (ref.3).
- 1/2" ballcock (system bleeding) (ref.4).
Serves to drain the cooling system of the generator
for general maintenance or for long periods of
inactivity.
- Water filter(inspectable) (ref.5).
It protects effectively thecooling circuit against intake
of mud, sand and seaweed.
Thefilter meshmust bethe fine type, itis advisable
to use the type with 2-470  m (micron) pitch.
Differentsizeswould notallow goodfilter efficiency.
- Antisiphon valve (ref.6): this valve brings the cooling
circuit to atmospheric pressure whenthe engine is off,
preventing the siphonage phenomenon.
It must be used when the base of the generator is
under the water line, and must be positioned at least
500mm (1.6ft) above sea level.
The drain pipe of the antisiphon valve must be
positioned under the valve thus preventing water
from accumulating in the pipe which must always
remain empty to allow air to pass through it when
the generator is switched off.
Itis advisable to runthe drainpipe through the bilge,
as small amounts ofwater may flow from it during
normal operation.
Two holeshave been made inthe casingto connect
the antisiphonvalve (ref.6).
