IMPACT-36 plus II Recreational Vehicle Generator
2.1LOCATION AND SUPPORT
◆2.1.1 GENERATOR LOCATION
The most desirable location for the generator set is between the vehicle's main frame members However, this is seldom possible. Most units must be installed on the side of the vehicle and are difficult to reinforce.
Many recreational vehicles have been factory equipped with an area for the generator set. Some vehicles 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 framework that is part of the recreational vehicle, as outlined in the paragraph entitled “Generator Support.”
•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 frequently serviced components, such as filters, oil drains, spark plugs and other common maintenance parts.
•The location must provide sufficient room to allow minimum clearance of at least 1 inch between all sides and
•The location must provide adequate cooling and ventilating air flow 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 made part of 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 horizontal beams. These beams should consist of (a)
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 sufficient 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 have the following:
(a)be able to support the weight of the generator; and
(b)provide sufficient restraint for the generator. One typical suspended mounting system is shown in Figure 2.2. The location of a suspended mounting system must be carefully planned, keeping the fol- lowing 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 generator is adequately protected, road test the installation through mud, water and slush.

•The installer must make certain that selected loca- tion will permit adequate cooling and ventilating air flow to be supplied.
