COOLING AND VENTILATING AIR

It is absolutely essential that an adequate flow of air
for cooling, ventilating and engine combustion be
supplied to the generator set. Without sufficient air-
flow, the engine/generator quickly overheats. Such
overheating can cause serious operating difficulties
and also may cause fire and personal injury. The
installer must make sure that sufficient air is avail-
able to the generator for cooling, ventilating and com-
bustion. The installer also must provide for a path
for exhausting the cooling air to the exterior of a com-
partment, if so equipped.
Never use discharged cooling air for heating or
permit such air to enter the vehicle interior.
This air contains deadly carbon monoxide gas
and other poisonous, flammable or explosive
gases.
