Recreational Vehicle Generator

2.3COOLING 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 airflow, 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 combustion. The installer also must provide for a path for exhausting the cooling air to the exterior of a compartment, if so equipped.

DANGER

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.

‹2.3.1 GENERATOR AIRFLOW

‹2.3.2 TESTING THE INSTALLATION

The manufacturer recommends testing the installa- tion 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:

Test the installation, especially if bringing in air from below the generator set.

2.4GASOLINE FUEL SYSTEM

The installation of a gasoline fuel system (Figure 2.10) for a recreational vehicle generator set must comply with applicable codes, standards and regula- tions. The entire fuel system must be completely free of leaks. There must be no possibility of gasoline vapors entering the vehicle interior.

Figure 2.10 – Generator Fuel System

Engine operation drives cooling fans for the two-stage cooling air system. A pressure fan draws cooling air into the bottom right side of the generator (Figure 2.9). This airflow cools the engine/generator and electronic components. The second part of the cooling system, a suction fan, draws air that is heated from a hot engine into a collector compartment at the left side of the unit. This heated air (although cooler than exhaust muffler) is then deflected out the bottom toward the ground.

DANGER

Gasoline is highly flammable, and its vapors are explosive. Comply with all codes, standards and regulations pertaining to gasoline fuel systems used in recreational vehicle generators. Properly install and maintain the fuel system and keep it entirely free of leaks. Gasoline vapors must not enter the vehicle interior.

Factory installed generator fuel system components include (a) fuel filter, (b) 12-volt DC electric pump,

(c)engine carburetor, and (d) interconnecting lines and fittings. Connect a fuel supply line to the fuel filter inlet. Use a flexible length of approved fuel hose between the fuel filter inlet connection and rigid fuel lines.
