2 PRESCRIPTIONS FOR SAFETY DURING INSTALLATION AND SETUP
• The personnel in charge of installation and starting of the generator must always wear a protective helmet; wear
safety shoes and overalls.
• Immediately change wet overalls.
• Use protective gloves.
• Do not leave disassembled parts, tools or anything else not forming part of the system on or near the engine.
• Never leave inflammable liquids or cloths soaked in inflammable liquids in proximity of the generator, near electric
equipment, (including lamps), or parts of the electrical system.
• Take the necessary precautions to prevent the danger of electrocution.
3 INSTALLATION
3.1 Characteristics of the installation space
The generator must be installed in a sufficiently
ventilated room, able to assure 800 m
3
/h air, which
corresponds to the quantity of air required for alternator
cooling and engine combustion.
The space must be separate and acoustically insulated
from living areas.
The generator should be positioned so that normal
maintenance operations can easily be carried out.
Propulsion motors are recommended for installation in
the area as long as they comply with the above-
mentioned conditions.
3.2 Fastening the unit to the ground
To fasten the unit securely, a base should be installed
to absorb vibrations and support the weight.
Drill holes in the base according to the instructions in
Fig. 1 .
3.3 Ventilation
The generator is equipped with an internal forced cooling
system by means of the alternator fan.
The quantity of air required for alternator cooling and
engine combustion is aspirated through the opening
shown in Fig. 2 , ref. A , and is expelled through the two
side vents shown in Fig. 2 , ref. B . Therefore, ensure
that these openings are always clear.
4 COOLING WATER CIRCUIT
The engine is cooled by an closed circuit system heat
exchanger.
On installation a sea water feed circuit should be fitted
for cooling and a waste system to expel the mixture of
flue gas and water.
4.1 Sea water feed system
Boats usually use one of two systems to collect water,
(Fig. 7 ).
1 Direct infeed system.
2 System with baffle.
mase recommends the direct infeed system, (Fig. 7 ,
ref. 1 ), since this system prevents water under pressure
entering the suction ducts and instead forms a pressure
which can easily be overcome by the water pump of
the electric generator.
Do not apply any type of protective hood to the direct
infeed system.
The baffle system might cause the following problems.
a If it is installed with the slots facing the prow.
In this case, during navigation and with the electric
generator off, pressure is accumulated in the water
infeed duct which might cause the system to fill up,
even as far as the exhaust port, allowing water to
enter the cylinders.
b If it is installed with the slots facing the stern.
In this case a depression might accumulate in the
water infeed duct during navigation, preventing the
water pump from starting up the cooling plant, or
limiting the capacity and subsequently causing the
electric generator to overheat.
