2.6 Cooling System

The engine fan draws cooling air through the openings
in the sides and end near the battery. The alternator
fan draws cooling air through openings on the side
walls of the enclosure. The cooling air mixes with the
engine exhaust and is discharged at the exhaust
outlet. See Figure 2-10. To prevent generator set
damage caused by overheating, keep the housing
cooling inlets and outlets clean and unobstructed at all
times.
Note: Do not block the generator set cooling air inlets
or mount other equipment near or above them.
Overheating and severe generator damage may
occur.
