INSTALLATION
The max continuous coolant temperature for this unit is
113°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
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.
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
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. 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.
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
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.
