QUIETPACT™ 75D Recreational Vehicle Generator

2.1 LOCATION AND SUPPORT

◆2.1.1 GENERATOR LOCATION

The most desirable location for the generator set is between the vehicle's main frame members.

Many recreational vehicles have been factory- equipped with an area for the generator set. Some may even have a generator compartment provided by the vehicle manufacturer.

Plan the generator location based on the following:

•The generator set must be installed on a frame- work that is part of the recreational vehicle, as out- lined in Section 2.1.2.

•The location must provide an access opening that is large enough to permit generator removal (unless the generator is to be removed from under- neath the supporting framework).

•The location must provide easy access to frequent- ly serviced components, such as, filters, oil drains, and other common maintenance parts.

•The location must provide sufficient room to allow minimum clearances for air circulation. If sound insulation is to be used on the compart- ment walls and ceiling, the minimum recom- mended clearance applies to the space between the generator and such insulation.

•The location must provide adequate cooling and ventilating airflow for the generator, without a great deal of work and expense.

◆2.1.2 GENERATOR SUPPORT

The generator must be securely attached to a metal framework that has been affixed to the vehicle frame structure by bolting or welding. The metal framework on which the generator will rest, and which will restrain the generator set, should consist of at least two hori- zontal beams. These beams should consist of (a) 1-1/2- inch square, 11-gauge steel tubing OR (b) 1-1/2-inch, 11-gauge angle iron.

The generator can be installed so that it sits on top of the horizontal support tubing, if the vehicle design permits. Another method is to suspend the generator below the horizontal support tubing by means of suit- able, structurally-sound metal framework. The fol- lowing general rules apply:

•Vehicle construction MUST be capable of support- ing the weight of the generator.

•Whether the generator is mounted above the hori- zontal support tubing or suspended below the tub- ing, the supporting frame used must be structural- ly sound.

•If the generator cannot be bolted directly to the supporting frame or support tubing, consider

using additional tubing, angle brackets or other supports to give the supporting frame suf- ficient strength.

◆2.1.3 SUSPENDED MOUNTING

If the generator will be suspended below the horizon- tal support tubing, the suspension method used with the vehicle frame members must (a) be able to sup- port the weight of the generator AND (b) provide suf- ficient restraint for the generator. One typical sus- pended mounting system is shown in Figure 2.1. The location of a suspended mounting system must be carefully planned, keeping the following general rules in mind:

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

•The installer must make certain that the selected location will permit adequate cooling and ventilat- ing airflow.
