2.1.4 GENERATOR RESTRAINT

Use four 3/8"-16 hardened steel bolts (Grade 5) to fas- ten the generator to the supporting frame or the sup- port tubing. These bolts must pass through (a) the gen- erator mounting base, (b) the compartment floor (if a compartment is used) and (c) the supporting frame- work (Figure 2.3). All bolts must be long enough so that when tight, at least three threads are visible past the retaining lock nuts. Refer to Section 2.2 for the location of the generator mounting holes.

Figure 2.3 – Typical Generator Restraint

2.2.2 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 rec- ommends 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 ply- wood with the grain of the wood at cross section for added strength (Figure 2.5).

Figure 2.5 – Typical Compartment Construction

2.2GENERATOR COMPARTMENTS

Whether the generator set is being installed inside a compartment specifically manufactured to house a gen- erator or inside a compartment that the installer con- structs, the compartment MUST meet certain specifi- cations as outlined in the following sections:

2.2.1 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)from the back for air circulation AFTER the compartment has been lined with metal and sound insulation (Figure 2.4).

NOTE:

Refer to “Figure 1.2 – Major Features and Dimensions” on Page 21.

If constructing a compartment, line the exterior (underside) of the compartment floor with 26- gauge galvanized steel.

All seams, splices and joints of the compartment

walls (unless vapor tight by design) should be caulked to prevent poisonous, flammable or explosive vapors from entering the vehicle interior.

NOTE:

Caulking must be done so that the caulking materi- al will stay in place permanently. Pressing such materials as putty tape onto joints and seams is NOT acceptable. A high quality silicone rubber base sealant is recommended.

Holes and openings made in the compartment walls to allow for the passage of electrical conduit, conductors, hoses, cables, etc., into the vehicle liv- ing area must be sealed vapor tight with silicone rubber base sealant.
