QUIETPACT™ 75 D Recreational Vehicle Generator
2.1 LOCATION ÄND SUPPORT
• 2.1.1 GENERATOR LOGVTION__________________
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
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 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 applies to the space between the gener­
ator 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 made part of the vehicle
frame structure by bolting or welding. The metal frame­
work 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) 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 th& 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 you are going to suspend the generator below the
horizontal support tubing, the suspension method
you use with the vehicle frame members must (a) be
able to support the weight of the generator AND (b)
provide sufficient restraint for the generator. One typ­
ical suspended mounting system is shown in Figure
2.1. The location of a suspended mounting system
must be carefully planned, keeping the following gen­
eral 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 to be supplied.
