2.3.3 COMPENSATING FOR RESTRICTIONS
Materials, such as, screening, louvers, or expanded metal, can
restrict the free flow of air. Compensate for this restriction by mak-
ing the actual air opening proportionately larger.
Some materials may offer only a 60 percent “free air inlet area.”
Other more efficient materials may provide up to a 90 percent free
air inlet area. The percentage of free air inlet opening is usually
available from the material’s supplier or manufacturer.
To determine the actual air inlet opening size required, divide
150 square inches (975 cm2) by the percentage of free air inlet
area for the material being used.
For example:
If planning to use screening with an 80 percent
free air inlet area, divide 150 (975) by 0.8, which results in 187.5
square inches (1,218.75 cm2). Minimum actual size of air inlet
opening in this case is 187.5 square inches (1,218.75 cm2).
2.3.4 TESTING
THE
INSTALLATION
The manufacturer recommends testing the installation to be sure
adequate cooling airflow is available to the unit, before placing the
unit into service. If the unit shows signs of overheating, enlarge the
air openings. Never place a unit into service until absolutely certain
that cooling and ventilation is adequate.
NOTE:
The installation must be tested, especially if bringing in air from
below the generator set.
2.4 DIESEL FUEL SYSTEM
The installation of a diesel fuel system (Figure 2.12) for a recre-
ational vehicle generator set must comply with applicable codes,
standards, and regulations. The entire fuel system must be com-
pletely free of leaks. There must be no possibility of fuel vapors
entering the vehicle interior.
Figure 2.12 – Generator Fuel System
All fuel types are potentially FLAMMABLE
and/or EXPLOSIVE and should be handled
with care. Comply with all laws regulating the
storage and handling of fuels. Properly install
and maintain the fuel system, and keep it
entirely free of leaks. Fuel vapors must not
enter the vehicle interior.
