ENGINE GENERATOR SET MOUNTING
The unit’s main frame must be bolted solidly to a solid base. The en-
gine-generator is mounted on channels which are attached with special
shock mounts to the main frame. This allows the engine-generator free
movement without affecting the base or surrounding equipment.
WARNING: EQUIPMENT DAMAGE:
Never mount these engine-generator sets to a wooden base/structure.
Over time, the wood will deteriorate and the unit mountings will come
loose. These units must be mounted to a steel or concrete base.
The unit should be mounted to allow ample working room around it.
A general rule to follow is five (5) feet of clearance from flammable
surfaces. But sufficient access must be provided for servicing the
equipment.
VENTILATION REQUIREMENTS
WARNING: EQUIPMENT DAMAGE:
It is the installer’s responsibility to ensure that there is sufficient cooling
air available to prevent the engine and generator from over heating.
Damage caused by overheating is not covered by warranty.
Providing proper air movement during your installation planning is
absolutely essential. You will need to provide a fresh air inlet as well as
a hot air outlet (to the outside of protection housing) for proper engine
performance. These engine-generator sets are equipped with unit
mount radiators and the engine is equipped with a pusher type fan. The
hot air from the face of the radiator must be ducted out of the enclo-
sure to ensure proper cooling. Failing to do so will allow the hot air to
recirculate around the radiator causing the engine to overheat, resulting
in an engine shutdown. If louvers are used in front of the hot air duct to
protect the unit from outside weather, the louvers should be 1
½
times
as large as the area of the radiator face to prevent back pressure.
In addition to a hot air discharge, you must plan a fresh air intake
opposite the radiator discharge. There fresh air inlets should also be
1
½
to 2 times larger than the radiator face. The extra air inlet area is
required to minimize restriction and to provide combustion air for the
engine. Do not block fresh air intakes with other equipment as this will
result in insufficient air flow to the engine for cooling. Installing them
opposite the hot air discharge will allow a sweeping flow of cooling air
across the engine, preventing hot spots.
FUEL INSTALLATION
The fuel supply should be as close to the engine as possible. This will
reduce the installation cost of fuel runs and minimize line losses. The
diesel fuel supply should be no more than 3 feet below the fuel inlet
pump. If your fuel supply is lower than 3 feet, you may have to install
an additional lift pump to bring the fuel up to the mechanical fuel pump
on the engine.
The information in this manual is offered to assist you in providing the
proper fuel for your engine. However, this information is only provided
to inform you of the engine’s requirements and assist in making
you aware of the decisions you must make. In no case should the
instructions or information provided be interpreted to conflict with any
local, state, or national codes. If in doubt, always consult your local fire
marshal or fuel supplier.
INSTALLING THE FUEL LINE
Engine-generator sets are properly adjusted before they leave the
factory. Connecting a fuel supply with adequate supply volume is
critical to reliable operation. Diesel units with optional base mounted
fuel tanks are pre-plumbed to the mechanical fuel pump on the engine.
Open skid mounted diesel units are often supplied with capped inlet
and return lines. The use of a suitable customer supplied flexible fuel
lines is essential between the engine and fuel supply to provide a
vibration break between your fuel supply and the engine.
WARNING: FIRE DANGER:
Connecting rigid fuel line (i.e. steel or copper line) directly to the inlet
fuel filter or fuel pump may cause the fuel line to crack during operation
creating a serious fire hazard.
