3.6 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 3-7. 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 above them. Overheating
and severe generator damage may occur.
