2-12. OPERATION IN BLOWING DUST OR SAND STORM CONDITIONS.
a.
If possible, provide a shelter for generator set. Use available natural barriers to shield generator set from blowing
dust or sand.
b.
Wet down dusty and sandy surface areas around generator set frequently If water is available.
c.
Keep all access doors closed, as much as possible, to prevent entry of dust and sand into housing assembly.
d.
Wipe dust and sand frequently from the generator set external surface and components. Wash exterior surfaces
frequently with clean water when generator set Is not operating
e.
Service engine air cleaner frequently to compensate for intake of additional dust or sand.
f.
Drain sediment frequently from fuel filter/water separator. When servicing fuel tank be careful to prevent dust or
sand from entering fuel tank.
2-13. OPERATION UNDER RAINY OR HUMID CONDITIONS . Keep fuel tank full to prevent condensation of moisture.
During dry periods when the set is not operating, open the doors and allow the set to dry out. Remove rust or other
corrosion and paint all damaged prepainted surfaces In accordance with service requirements.
2-14. OPERATION IN SALT WATER AREAS.
a.
Salt water causes corrosive action on metal. Care must be taken to avoid equipment contact with salt water. If
contact Is made, or if the unit Is exposed to salt spray, wash the generator set frequently with clean, fresh water.
b.
Remove rust or other corrosion and paint all damaged prepainted surfaces In accordance with service
requirements.
2-15. OPERATION AT HIGH ALTITUDES . The generator set will operate at elevations up to 1500 feet (457 meters)
above sea level without special adjustment or reduction In load. A reduction in the load at higher altitudes may be
necessary, since engines are more likely to overheat. The following derating factors are applicable:
60 Hz
750 kW to 1500 feet (457 meters at 125°F (520C) (sea level) to 90°F (320C) (1500 feet (457 meters))
600 kW to 5000 feet (1410 meters) at 107°F (420C)
563 kW to 8000 feet (2435 meters) at 950F (350C)
50 Hz
625 kW to 1500 feet (457 meters) at 1250F (52°C) (sea level) to 90°F (320C) (1500 feet (457 meters))
500 kW to 5000 feet (1410 meters) at 107°F (420C)
469 kW to 8000 feet (2435 meters) at 950F (35°C)
2-16. EMERGENCY OPERATION ON JP5 FUEL. Generator sets require no adjustments to engine timing or fuel
injectors for operation on JP5 fuel. When JP5 fuel is used, power output must be reduced by a factor of 20 percent.
