INSTALLATION
GENERAL
Plan the installation carefully to ensure maximum
operating efficiency. Use this manual as a general
guide.
Recommendations in this manual are based on
extensive tests under favorable operating conditions.
Abide by pertinent local codes regulating installation
arid operation of internal combustion engines.
Protect walls and partitions through which exhaust
pipes pass with a metal shield (Figure 3).
Install a suitable muffler preferably as close to the
engine as practicable. Pitch exhaust pipes downward,
or provide a condensation trap at point where a rise in
the exhaust system begins.
LOCATION
Engine location is determined chiefly by the intended
application. Provide adequate access for service and
repair. Protect the engine from adverse weather.
Consider the location of related systems, such as
fuel,
exhaust, and ventilation.
MOUNTING
Secure the engine to a
rigid,
level foundation. Foun-
dations must be sturdy enough to withstand distor-
tion and retain alignment with load equipment.
If necessary to exceed 23-degree tilt angle, consult
the factory. Compensate for any tilt when checking
crankcase oil.
VENTILATION
Ventilation is needed to cool the engine and support
combustion. Avoid recirculation of ventilating air. See
SPECIFICATIONS section for air flow requirements
and vent sizes.

Locate vents so air flow from the inlet to the outlet will
pass over the engine. The outlet should be slightly
higher than the inlet.
An optional air shutter may be used in the outlet duct
to control engine temperature by regulating air flow.
Air shutters also prevent back flow of cold air during
engine shutdown.
When shutters are used between the engine and
•
outlet vent, use a canvas section to restrict vibration.
EXHAUST
WARNING |
Pipe 9as ou,slde an
y enclosure. Exhaust gas
^^n^^^^^J is poisonous.
Exhaust pipes must not terminate near inlet vents.
Avoid sharp bends by installing sweeping, large
radius elbows. Use flexible seamless section tubing
between the engine and any rigid pipe to restrict
vibration.
Increase the exhaust pipe one size for each
additional 10-foot length.
FUEL
TANK AND
LINES
Install the fuel tank so that the vertical distance from
bottom of the tank to the fuel pump does not exceed
six feet. Auxiliary fuel pumps are available which
provide an additional eight-foot fuel lift.
Avoid gravity feed of fuel to the engine. Provide a
siphon break if tank is above pump. When sharing a
fuel tank, do not connect to an existing line at a point
above the fuel supply level.
These diesel engines require a fuel supply line and a
separate return line. Install the fuel supply linefrom
tank to the
1/8-inch
pipe inlet in the fuel pump.
Connect the fuel return line to the fitting (7/16-24
size) onthe injection pump (Figure 4) to the top of the
fuel supply tank. Use approved flexible fuel lines at
theengine to absorb vibration. Besuretherearenoair
leaks in the suction line.
