IMPACT-36 plus II Recreational Vehicle Generator

◆2.1.4 GENERATOR RESTRAINT

Use four 5/16"-18 hardened steel bolts (Grade 5) to fasten the generator to the supporting frame or the support tubing. These bolts must pass through (a) the generator mounting base, (b) the compartment floor, if a compartment is used, and (c) the support- ing framework (Figure 2.3). All bolts must be long enough so that when tight, at least 3 threads are vis- ible past the retaining lock nuts. Refer to “COM- PARTMENT” section for location of generator mount- ing holes.

2.2GENERATOR COMPARTMENTS

The generator set may or may not be installed inside a compartment that is constructed specifically for housing a generator. This section applies to generator compartments when they are installed. The following general rules apply to compartments:

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

IMPORTANT: 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, with the floor made of a double thickness of plywood for added strength.

•All seams, splices and joints of the compartment walls (unless vapor tight by design) should be caulked.

IMPORTANT: CAULKING MUST BE DONE SO THAT THE CAULKING MATERIAL WILL STAY IN PLACE PERMANENTLY. PRESSING SUCH MATERIALS AS PUTTY TAPE ONTO JOINTS AND SEAMS WILL NOT MEET THAT REQUIREMENT. A HIGH QUALITY SIL- ICONE RUBBER SEALANT IS RECOMMENDED.

•Holes and openings through the compartment walls for passage of electrical conduit, conductors, etc, into vehicle living area must be sealed vapor- tight with silicone rubber base sealant.

•If using flexible metal conduit, seal the conduit at the end where it terminates inside the junction box. Flexible metal conduit is NOT vapor tight along its entire length.

•Seams and joints of the galvanized steel (whether used as a liner or the compartment itself) must be lapped and mechanically secured. Such seams may be manufactured, welded, bolted, riveted, or screwed. Manufactured lock seams are shown in Figure 2.4.
