◆ 2.3.4 TESTING THE INSTALLATION

 

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, you will need to

 

enlarge the air openings. Never place a unit into

 

service until absolutely certain that cooling and

 

ventilation is adequate.

 

NOTE:

 

You must test the installation, especially if you

 

bring in air from below the generator set.

◆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 you will use.

For example: If you plan 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).

2.4DIESEL 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

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.
