•Protect the generator against road splash and debris. Baffles or splash guards may be required to protect cer- tain areas of the generator. To make sure the generator is adequately protected, road test the installation through mud, water and slush.

•The installer must make certain that the selected location will permit adequate cooling and ventilating airflow to be supplied.

◆6.1.4 GENERATOR RESTRAINT

Use four 3/8"-16 hardened steel bolts (Grade 5) to fasten the generator to the supporting frame or the support tub- ing. These bolts must pass through (a) the generator mounting base, (b) the compartment floor (if a compart- ment is used) and (c) the supporting framework (Figure 6.3). All bolts must be long enough so that when tight, at least three threads are visible past the retaining lock nuts. Refer to Section 6.2 for the location of the gen- erator mounting holes.

◆6.2.2 COMPARTMENT CONSTRUCTION

•The generator compartment should be either con- structed of, or lined with, 26-gauge galvanized steel.

NOTE:

Aluminum is NOT an acceptable alternative to galvanized steel due to aluminum’s low melting point.

•If the compartment is lined with galvanized steel, it may be constructed of any material. Generac recom- mends that the compartment be constructed of 1/2- inch thick plywood (not strandboard), with the floor made of a double thickness of 1/2-inch plywood with the grain of the wood at cross section for added strength (Figure 6.5).

6.2 GENERATOR COMPARTMENTS

Whether the generator set is being installed inside a com- partment specifically manufactured to house a generator or inside a compartment that the installer constructs, the compartment MUST meet certain specifications as out- lined in the following sections:

◆ 6.2.1 COMPARTMENT SIZE

Plan the compartment size carefully. Provide a mini- mum clearance of 1/2 inch (13 mm) on the front and top, 1 inch (25 mm) on the sides, and 1/2 inch (13 mm)
