Section 6 – Installation

Using a combination of sound insulating materials can often reduce noise more effectively than a single material. For example, a sheet of lead or visco-elastic material, along with a layer of other acoustical mate- rial, is more effective than when a single material is used.

‹6.2.4 ACOUSTICS

For additional noise abatement, the installer may wish to consider the following:

•Using special sound insulating materials.

•Construction of a special noise abatement com- partment.

NOTE:

Any method used to reduce noise must not adversely affect the flow of cooling and ventilating air into or out of the compartment.

In addition to the effective use of sound insulating materials, construction of a special noise abatement compartment might be considered to reduce noise levels. Such a compartment might be constructed as follows (Figure 6.7):

•Use 5/8-inch thick or 3/4-inch thick plywood in the compartment.

Recreational Vehicle Generators

DANGER

To prevent fire or explosion, do not install any insulation or other absorbent materials on the interior or underside of the compartment floor.

•Seal all compartment door edges to prevent noise leakage around the door perimeter.

•Line the compartment door interior (except for air openings) with suitable, fireproof sound insulation (such as 1-inch (25 mm) thick fiberglass with a 2- pound density).

‹6.2.5 COMPARTMENT FLOOR CUTOUTS

Provide openings in the generator compartment for the following items (Figure 6.8):

•Engine exhaust and cooling air outlets

•Generator cooling air inlet

•Four holes for passage of generator mounting bolts. See Section 6.1.4.

DANGER

Fuel lines and exhaust piping must not pen- etrate into the vehicle living area.

•Construct the compartment floor of a double thick- ness of 5/8-inch or 3/4-inch plywood.

•Line the compartment interior walls and floor, as well as the underside of the floor, with 26-gauge galvanized steel.

•Vapor seal all compartment seams and joints.

•Over the galvanized steel lining, install a combi- nation of acoustical materials as mentioned in Section 6.2.3.

6.3COOLING 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.

‹6.3.1 GENERATOR AIRFLOW

Engine operation drives cooling fans for the two-stage cooling air system. A pressure fan draws cooling air into the top of the generator (Figure 6.9). This airflow cools the engine/generator and electronic compo- nents. The second part of the cooling system, a suc- tion fan, draws air that is heated from a hot engine into a collector pan at the base of the unit. This heated air (although cooler than exhaust muffler) is then deflected out the bottom toward the ground.
