Section 2 - Installation
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.
4 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.
4 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 t
3 rp-
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.
