INSTALLATION
The max continuous coolant temperature for this unit is
250°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) is in
the “off” position and the unit starting battery is
disconnected.
GENERAL INFORMATION
This engine-generator set is generally supplied as weather
enclosed packages for quick installation on an outdoor
concrete pad. They are also available as open skid mounted
units for indoor installation in a building or protective
enclosure, properly ventilated, supplied by the installer. The
factory weather enclosures are acoustical housing intended
for outdoor installation only. Factory weather enclosed
units are not intended to be used indoors and no support is
available to assist in re-engineering finished packaged units.
All versions must be bolted to a solid base for proper
operation. A properly designed concrete pad is necessary
for stationary operation. Consult a qualified, licensed
electrician or contractor to install and wire the gen-set. The
installation must comply with all national, state, and local
codes.
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 information in this manual is offered only as a guide to
finalizing your installation plans.
NOTICE
For full service switching of the entire load, the ATS
must be ‘SE’ (Service Entrance) rated or must have a
properly rated fusible disconnect installed before the
ATS to protect the contacts.
ENGINE GENERATOR SET MOUNTING
The unit’s main frame must be bolted solidly 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.
The unit should be mounted to allow ample working room
around it. A general rule to follow is to allow 24 inches or
more of clearance for maintenance. Follow local codes for
clearance from combustible surfaces.
VENTILATION REQUIREMENTS
OPEN SKID
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.
The WINCO installation manual OPM-112 contains
information on indoor, open skid installations and
is available electronically through our website or by
requesting a copy from the factory.
EXHAUST INSTALLATION
WARNING: PERSONAL INJURY
Improper exhaust installation will allow dangerous
gases to seep into enclosed spaces causing a hazard to
your health and/or death.
All exhaust must be piped out of the enclosure. When
selecting a location to exhaust fumes make sure that the
potential for contact with people is controlled. Exhaust can
enter buildings through windows, ventilation systems and
other openings if proper precautions are not followed.
The exhaust must be isolated from the vibration of the
engine. If the exhaust is connected in a rigid system it will
result in damage to the engine. The generator comes
equipped with an engine mounted flex pipe to aid your
installation. Ensure proper alignment with the generator.
The flex can be eliminated if it is pushed to one side to make
a connection.
The most direct path possible should be used to get to the
outside of the enclosure. Each bend restricts the pipe and
