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 can be supplied as weather
enclosed, trailered packages. The DOT certified trailer
is required for mobile applications. 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. The factory weather enclosures are acoustical
housing intended for outdoor use only. Units are not
intended to be used indoors and no support is available to
assist in re-engineering finished packaged units.
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. 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.
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.
