OPM-143/E
INSTALLATION
The max continuous coolant temperature for this unit is
226°F. This unit should be installed in a well ventilated area,
ensuring the exhaust air cannot be recirculated back into
the engine.
CAUTION:
This unit will get hot while it is running and for some time
afterward.
WARNING: PERSONAL INJURY:
Before proceeding with the installation, be sure the engine
control is in the “stop” position and the emergency stop
depressed. Also, be sure the generator MLCB (main line
circuit breaker) in is the “off” position and the unit starting
battery is disconnected.
GENERAL INFORMATION
This series of engine-generator sets are designed and built
as open power units, meaning no weather protection has
been provided. These units must be installed inside of an
enclosure that will provide proper protection from the
elements.
The WINCO installation manual OPM-112 contains
additional information on indoor installations and
is available electronically through our website or by
requesting a copy from the factory.
Before beginning the installation process, recheck the
voltage, phase, and amperage rating of the generator
set. Be certain it can handle the intended load and are
compatible with the intended loads. Plans for installation
should be prepared with proper attention to mechanical
and electrical engineering detail to assure a satisfactory
system installation. The installation must comply with all
national, state, and local codes.
The information in this manual is offered only as a guide to
finalizing your installation plans and does not substitute for
sound engineering judgment for the specific application.
ENGINE GENERATOR SET MOUNTING
The unit’s main frame must be bolted securely to a solid
base. The engine-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.
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 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
enclosure 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
and damage. If louvers are used in front of the hot air duct
to protect the unit from outside weather, the louvers should
be 1½ times as large as the area of the radiator face to
prevent back pressure.
This generator is equipped with a duct flange designed to
make installation simpler. The flange should not be placed
closer than 0.75 in. to the edge of the structure or other
solid surfaces. The radiator is mounted on rubber vibration
isolators that allow it to move. Placing the duct flange too
close to a wall can result in contact that will damage the
radiator resulting in costly repairs.
Foam or other seals can be used to form a tight lip forcing
all of the air from the engine fan out of the enclosure.
In addition to a hot air discharge, you must plan a fresh air
intake opposite the radiator discharge. Their fresh air inlets
should be 1½ 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.
