seawater. There is coolant recovery tank for the
engine coolant mounted on the bulkhead near the
generator. Make sure the uid level in the cool-
ant recovery tank is kept between the maximum
and minimum lines of the tank. You should also
check the exhaust port for water ow each time
the generator is started. If there is no discharge
within thirty seconds, shut down the generator,
then nd and correct the problem.
The seawater cooling system includes a strainer
that prevents debris in the seawater from enter-
ing the cooling pump. The strainer and a seacock
valve is located in the mechanical systems com-
partment bilge near the generator. It is important
to check and clean the strainer regularly to ensure
the seawater system can circulate enough water to
provide cooling for the closed cooling and exhaust
systems on the generator. You should also make
sure the generator seacock valve is open and
check the exhaust port for water ow each time
the generator is started. If there is no discharge
within thirty seconds, shut down the generator
and nd and correct the problem.
Refer to the Raw Water Systems Maintenance
section in the Raw Water System Chapter of this
manual for instructions on cleaning the generator
sea strainer.
Notice
The generator may not be able to operate
all 120 volt accessories at the same time.
POWER MANAGEMENT PRACTICES may need
to be observed depending on the AC power
load.
Notice:
Generators consume DC electrical current
and charge the House batteries just enough
to compensate for the DC electrical current
the engine requires to operate. Therefore, it
is important to activate the battery chargers
to maintain the House and Engine batteries
whenever the generator is running.
The generator fuel system is equipped with a water
separating fuel lter and operates much like the
fuel system for the main engines. Please refer to
the Fuel System chapter for more information on
the generator fuel system.
You should also read the generator owner’s man-
ual for detailed information on the safe operation
and maintenance of the generator.
