Generac 005411-0 Manual De Usuario

For additional noise abatement, the installer may wish to consider 

the following:

Using special sound insulating materials.

• 

Construction of a special noise abatement compartment.

• 

ment.
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 2.7):

Use 5/8-inch thick or 3/4-inch thick plywood in the compart-

• 

ment.

Construct the compartment floor of a double thickness 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 combination of acousti-

• 

cal materials as mentioned in "Sound Insulating Materials".



 

 To prevent fire or explosion, do not install 

any insulation or other absorbent materials 

on the interior or underside of the compart-

ment 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).

Provide openings in the generator compartment for the following 

items (Figure 2.9):

Engine exhaust and cooling air outlets

• 

Generator cooling air inlet

• 

Four holes for passage of generator mounting bolts. See 

• 

"Generator Restraint".

 Fuel lines and exhaust piping must not pen-

etrate into the vehicle living area.

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 available to the generator for cooling, ventilat-

ing and combustion. The installer also must provide for a path for 

exhausting the cooling air to the exterior of a compartment, if so 

equipped.

 Never use discharged cooling air for heating 

or permit such air to enter the vehicle inte-

rior. This air contains deadly carbon monox-

ide gas and other poisonous, flammable or 

explosive gases.

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 2.8). 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 col-

lector pan at the base of the unit. This heated air (although cooler 

than exhaust muffler) is then deflected out the bottom toward the 

ground.
