Cooling System

The engine fan draws cooling air through the openings in the sides. The alternator fan draws cooling air throu gh an opening on
the side wall of the enclosure. The cooling air mixes with the engine exhaust and is discharged at the exhaust outlet. See th e
service view section for air intake and exhaust locations. 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.

outlet.
Periodically inspect the exhaust system components for cracks, leaks, and corrosion.

Check for corroded or broken metal parts and replace them as needed.
