Section 6 - Installation INSTALLATION
PRIMEPACT 66G and 66LP Recreational Vehicle Generators
Protect the generator against road splash and debris.
Baffles or splash guards may be required to protect cer­
tain areas of the generator. To make sure the generator
is
adequately protected, road test tire installation
through mud, water and slush.

6.2 GENERATOR COMPARTMENTS
Whether the generator set is being installed inside a com­
partment specifically manufactured to house a generator
or inside a compartment tliat the installer constructs, the
compartment MUST meet certain specifications as out­
lined in the following sections:
♦ 6.2.1 COMPARTMENT SIZE________________________
Plan the compartment size carefully. Provide a mini­
mum clearance of 1/2 inch (13 mm) on the front and
top, 1 inch (25 mm) on the sides, and 1/2 inch (13 mm)
from the back for air circulation .ATTER the compart­
ment has been lined with metal and sound insulation
(Figure 6.4).
NOTE;
Refer to “Figure 5.2
Dimensions” on Page 21.

• The installer must make certain that the selected
location will permit adequate cooling and ventilating
airflow to be supplied.
♦ 6.1.4 GENERATOR RESTRAINT
Use four 3/8"-16 hardened steel bolts (Grade 5) to fasten
the generator to the supporting frame or the support tub­
ing. These bolts must pass through (a) the generator
mounting base, (b) tlie compartment floor (if a compart­
ment
is used) and (c) the supporting framework
(Figure 6.3). All bolts must be long enough so that when
tight, at least three threads are visible past the retaining
lock nuts. Refer to Section 6.2 for the location of the gen­
erator mounting holes.
Figure 6.3 - Typical Generator Restraint
• 6.2.2 COMPARTMENT CONSTRUaiON •
• The generator compartment should be either con­
structed of, or lined with, 26-gauge galvanized steel.
NOTE:
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 recom­
mends that the compartment be constructed of 1/2-
inch thick plywood (not strandboard), with the floor
made of a double thickness of 1/2-inch plywood with
the grain of the wood at cross section for added
strength (Figure 6,5).
