1.1 Introduction
The information in this section applies to all installations.
Review this section and the safety precautions before
starting the installation procedure. The generator set
specification sheet also contains data that may be
required during the installation process.
The generator set and accessories must be installed by
a trained, authorized Kohler distributor, dealer, or
authorized representative. The installation must comply
with all applicable national and local codes.
1.2 Enclosed and Open Generator
Sets
Enclosed generator sets include a factory-supplied
weather or sound housing. The exhaust systems of
enclosed units are complete for outdoor installations.
Review Section 1 and then refer to Section 3 for the
outdoor installation of enclosed units.
Note: Do not install enclosed units inside a
building.
Open generator sets do not include a factory-supplied
weather or sound enclosure. Install open generator sets
inside a building with the exhaust gas piped safely
outside.
Adequate cooling and combustion air are
required. Review Sections 1 and 2 for the installation of
open units before proceeding to the installation
procedure in Section 3.
Note: Do not install open commercial generator
sets in residential applications.
1.3 Location Factors
Ideally, the generator set should be mounted on
concrete at ground level. For above-ground installations,
including roof installations, weight considerations are
especially important.
determine whether the structure can support the weight
of the generator set.

Section 1 General
The location of the generator set must:
D
Support the weight of the generator set and related
equipment such as batteries, radiators, and mounting
pad(s). Keep in mind that the mounting pad weight
may exceed the weight of the generator set.
D
Meet applicable fire rating codes and standards.
D
Position the generator set over a noncombustible
surface. Do not allow accumulation of combustible
materials under the generator set.
D
Permit vibration isolation to reduce noise and prevent
damage.
D
Be clean, dry (open units), and not subject to flooding.
D
Allow ventilation with a minimum amount of ductwork.
(open units)
D
Provide clearance for cooling air flow and access for
service. See Section 3.2 for required clearances
around the generator set.
D
Allow safe expulsion of exhaust.
D
Minimize the risk of public or unauthorized access.
1.4 Mounting Surface
The manufacturer recommends a single, level concrete
mounting pad. This method provides maximum stability
for the generator set. The recommended mounting pad
dimensions for open and enclosed units are shown in
the dimension drawings in Section 7.
Refer to the generator set dimension drawings for
conduit and fuel-line placement. The drawings give
dimensions for electrical and fuel connection roughins
and stubups.
1.5 Vibration Isolation
The generator set is equipped with neoprene vibration
isolators. Connections between the generator set or its
mounting base and any conduits, fuel lines, or exhaust
piping must include flexible sections to prevent
breakage and to isolate vibration.
