Section 6. Installation
The safe and successful operation of a mobile power
system depends primarily on the installation. Use this
section as a guide to install the mobile generator set;
then refer to the operation section preceding for
generator set operating instructions.
RV/Mobile generator set installations must comply with
the Kohler-detailed installation instructions following.

Generator set installation must also comply with state
and local requirements.

Use current dimension drawings and wiring diagrams.
6.1 Location
Locate the generator set to allowfor easyaccess to the
generator set’s engine, controller, cooling system, and
fuel system components for routine service.
Beforemakingfinalplansfor locatingthegeneratorset,
consider the following concerning the set and the
proposed location.
1. Ensure that the location allows sufficient room to
maintain required minimum clearances.
2. Ensurethatthelocationprovidesenoughairflowto
allow required cooling.
3. Ensure that the location is strong enough to
support the generator set weight.
4. Ensure that the location provides ample room for
routine maintenance.
See current generator set specification sheet or
dimension drawings following for generator set
dimensions.
Allow clearance for vibration and cooling during
operation. Minimumclearanceforvibration andcooling
(top, front, rear, and sides) is 1 1/2 in. (38 mm).
Generator Set Compartment

compartment. Consider the following factors when
installing a generator set in a compartment.
Minimumclearance. Allowclearancefor vibrationand
cooling during operation. Minimum clearance for
vibration and cooling (top, front, rear, and sides) is
1 1/2 in. (38mm). Observe theminimum clearancesto
ensure that the sides of the compartment and the
generator set do not rub while operating the generator
set or driving the vehicle.
Additional clearance. Routine generator set service
requires additional clearance from those listed above.
Design the compartment to allow for sufficient room to
easily remove the generator set to perform major
service.
Sound-deadening material. Line the compartment
with a good sound-deadening material. Select a
fireproof, or fire resistant material with a fire-retardant
adhesive. A 3-layer foam material does an efficient job
ofabsorbingsound. Cuttosizethismaterialandbondto
a clean, dry surface.
NOTE
Do not install combustible insulation near exposed
exhaust-system components.
Compartment size. Consider the thickness of the
sound-deadening or insulating material used to line the
compartment when planning compartment size. If
necessary, enlarge the compartment to maintain
minimum clearance requirements.
Compartment door. Also keep in mind that the
compartment door must have air-intake openings
havingafreeareaequaltoorgreaterthanthatspecified
under Air Requirements in the Specification Sheet.
Vapor-tight compartment. Ensure a vapor-tight
compartment by completely sealing all crevices to
prevent exhaust or other fumes from entering the
vehicle.
Road splash. Avoid road splash and the possibility of
igniting combustible material beneath the vehicle by
enclosing all unnecessary free space beneath the
generator set compartment.
