2.5 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 w alls of
the enclosure. The cooling air mixes with the engine
exhaust and is discharged at the exhaust outlet. See
Figure 2-11. 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.
