DANGER
 Only qualified electricians or contractors should
attempt such installations, which must comply
strictly with applicable codes, standards and regu-
lations.

UNPACKING/INSPECTION

After unpacking, carefully inspect the contents for damage.
• This standby generator set is ready for installation with a
factory supplied and pre-mounted base pad and has a weather
protective enclosure that is intended for outdoor installation
only.
• This UL listed standby generator set may be packaged with
an automatic transfer switch with built in load center. The
combination transfer switch and load center is pre-wired with
a two foot and 30 foot conduit. Circuit breakers for emergency
circuit connections are included (if equipped).
• This UL listed, 2-pole switch is rated at 100
at 250 volts maximum. The 100 Amp transfer switch is for
indoor use only. The 200 Amp transfer switch is for indoor/
outdoor use (if equipped).

If this generator is used to power electrical load
circuits normally powered by a utility power
source, it is required by code to install a transfer
switch. The transfer switch must effectively isolate
the electrical system from the utility distribution
system when the generator is operating (NEC 700,
701 & 702). Failure to isolate an electrical system
by such means will result in damage to the gen-
erator and also may result in injury or death to
utility power workers due to backfeed of electrical
energy.

If any loss or damage is noted at time of delivery, have the
person(s) making the delivery note all damage on the freight bill
or affix their signature under the consignor's memo of loss or
damage.
If a loss or damage is noted after delivery, separate the damaged
materials and contact the carrier for claim procedures.
"Concealed damage" is understood to mean damage to the
contents of a package that is not in evidence at the time of
delivery, but is discovered later.
To properly open the roof, press down on the center top lip and
release the latch. If pressure is not applied from the top, the roof
may appear stuck. Always verify that the side lock is unlocked
before attempting to lift the roof.

PROTECTION SYSTEMS

Unlike an automobile engine, the generator may have to run for
long periods of time with no operator present to monitor engine
conditions. For that reason, the engine is equipped with the
following systems that protect it against potentially damaging
conditions:
1. Low Oil Pressure Sensor
2. High Temperature Sensor
3. Overcrank
4. Overspeed
5. RPM Sensor
6. Low Battery
There are readouts on the control panel to notify personnel that
one of these failures has occurred. There is also a System Set
LED (single cylinder) or a Status message on the display (V-twins)
that displays when all of the conditions described in the "System
Set LED" section are true.
NEC REQUIREMENT FOR ARC FAULT CIRCUIT
INTERRUPTION BREAKER FOR BEDROOMS
In 2001, the National Electric Code (NEC) introduced a
requirement for new construction. This new requirement indicates
the need for Arc Fault Circuit Interrupters to be used to protect the
complete branch circuit that feeds a dwelling bedroom. The actual
NEC requirement is indicated below.
SECTION 210.12 ARC FAULT CIRCUIT INTERRUPTER
PROTECTION
1. Definition: An arc fault circuit interrupter is a device
intended to provide protection from the effects of arc faults
by recognizing characteristics unique to arcing and by
functioning to de-energize the circuit when an arc fault is
detected.
2. Dwelling Unit Bedrooms: All branch circuits that supply
125 volt, single-phase, 15 and 20 ampere outlets installed
in dwelling unit bedrooms shall be protected by an arc fault
circuit interrupter listed to provide protection of the entire
branch circuit.
