◆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 making the actual air opening pro- portionately larger.

Some materials may offer only a 60 percent “free air inlet area.” Other more efficient materials may pro- vide up to a 90 percent free air inlet area. The per- centage 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 mater- ial 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).

Generac 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 bring- ing in air from below the generator set.

2.4DIESEL FUEL SYSTEM

The installation of a diesel fuel system (Figure 2.12) for a recreational vehicle generator set must comply with applicable codes, standards, and regulations. The entire fuel system must be completely free of leaks. There must be no possibility of fuel vapors entering the vehicle interior.

Figure 2.12 – Generator Fuel System

DANGER

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.
