TM 5-6115-593-12TO 35C2-3-463-1keep dirt and grit out of the fuel tank.2-16. OPERATION UNDER RAINY OR HUMIDCONDITIONS. The housing kit must be installed foroperation under rainy or humid conditions. During dryperiods when the set is not operating, open the doorsand allow the set to dry out. Drain water and sedimentfrom fuel tank more frequently.2-17. OPERATION IN SALT WATER AREAS.a.Housing Kit must be installed.b.Salt water causes corrosive action on metal.Care must be taken to avoid equipment contact with saltwater. If contact is made, or if the unit is exposed to saltspray, wash the generator set frequently with clean,fresh water.c.Remove rust or other corrosion and paint alldamaged pre-painted surfaces in accordance withservice requirements.2-18. OPERATION AT HIGH ALTITUDES. Thegenerator set will operate at elevations up to 1500 feet(457 meters) above seal level without specialadjustment or reduction in load. A reduction in the load athigher altitudes may be necessary, since engines are morelikely to overheat. The following derating factors areapplicable.60 Hz500 KW to 1500 ft ( 457 m) at 125°F (52°C)400 KW to 5000 ft (1410 m) at 100°F (39°C)375 KW to 8000 ft (2435 m) at 90°F (32°C)50 Hz417 KW to 1500 ft ( 457 m) at 1250F (52°C)332 KW to 5000 ft (1410 m) at 100°F (39°C)312 KW to 8000 ft (2435 m) at 90°F (32°C)2-19. OPERATION IN SNOW. The housing kit must beinstalled for operation in snow. Drain water and sedimentfrom fuel tank more frequently. Check coolant anti-freezeprotection and check batteries. Ensure that drifting snowdoes not obstruct normal cooling air flow.2-20. EMERGENCY OPERATION ON JP5 FUEL.Engine/generator sets require no adjustments to enginetiming or fuel injectors for operation on JP5 fuel. WhenJP5 fuel is used, power output is reduced by a factor of 20percent.2-47/(2-48 blank)
