Power Systems, Inc. (Generac) warrants that its standby generator will be free
from defects in material and workmanship for the items and period set forth
below. Generac will, at its option, repair or replace any part(s) which, upon
examination, inspection and testing by Generac or an Authorized/Certified
Generac Service Dealer, is found to be defective. Any equipment that the

Authorized/Certified Generac Service Dealer. This warranty applies only to
Generac emergency automatic standby generators used in “Standby” applications
as Generac has defined Standby. Scheduled Maintenance, as outlined by the
generator owner’s manual, is required. This Scheduled Maintenance should be
performed by an Authorized/Certified Generac Service Dealer. This will verify
service has been performed on the unit throughout the warranty period.

Introduction
Thank you for purchasing this compact, high perfor-
mance,
air-cooled, engine-driven generator. It is
designed to automatically supply electrical power to oper-
ate critical loads during a utility power failure.
This unit is factory installed in an all-weather, metal
enclosure intended exclusively for outdoor installation.
This generator will operate using either vapor withdrawn
liquid propane (LP) or natural gas (NG).
NOTE: This generator is suitable for supplying typical
residential loads such as induction motors (sump pumps,
refrigerators, air conditioners, furnaces, etc.), electronic
components (computer, monitor, TV, etc.), lighting loads,
and microwaves, when sized correctly. This unit is
equipped with a Wi-Fi® module, which allows the genera-
tor owner to monitor generator status from anywhere
they have Internet access.
NOTE: Wi-Fi® is a registered trademark of Wi-Fi Alli-
ance®.
The information in this manual is accurate based on
products produced at the time of publication. The manu-
facturer reserves the right to make technical updates,
corrections, and product revisions at any time without
notice.
Safety Rules
The manufacturer cannot anticipate every possible cir- cumstance that might
involve a hazard. The alerts in this manual, and on tags and decals affixed to
the unit, are not all inclusive.
If using a procedure, work method, or operating technique that the
manufacturer does not spe- cifically recommend, verify that it is safe for
others and does not render the equipment unsafe.
Throughout this publication, and on tags and decals affixed to the unit,
DANGER, WARNING, CAUTION, and NOTE blocks are used to alert personnel to
special instructions about a particular operation that may be haz- ardous if
performed incorrectly or carelessly. Observe them carefully. Alert definitions
are as follows:
A DANGER
Indicates a hazardous situation which, if not avoided,
will result in death or serious injury.
(000001)
AWARNING
Indicates a hazardous situation which, if not avoided,
could result in death or serious injury.
(000002)
A CAUTION
Indicates a hazardous situation which, if not avoided,
could result in minor or moderate injury.
Protection Systems
The generator may need to run for long periods of time
with no operator present to monitor engine or generator
conditions. The generator is equipped with protection
systems to automatically shut down the unit to protect
against potentially damaging conditions. Some of these
systems include:
Alarms:
• High Temperature
• Low Oil Pressure
• Overcrank
• Overspeed
• Overvoltage
• Underspeed
• RPM Sensor Loss
• Controller Fault
• Wiring Error
• Stepper Overcurrent
• Undervoltage
• Overload
Warnings:
• Charger Warning
• Exercise Set Error
• Charger Missing AC
• USB Warning
• Low Battery
• Download Failure
• Battery Problem
The control panel contains a display alerting the operator
when a fault condition occurs. The above list is not all-
inclusive. See Operation for more information about
alarms and control panel operation.
NOTE: A warning indicates a condition on the generator
which should be addressed, but will not shut down gener-
ator. An alarm shuts down the generator to protect sys-
tem from any damage. In event of an alarm, an owner
can clear the alarm and restart generator prior to contact-
ing an IASD. Contact an IASD if the intermittent issue
occurs again.
Emissions
The United States Environmental Protection Agency (US
EPA) (and California Air Resources Board (CARB), for
engines/equipment certified to California standards)
requires this engine/equipment to comply with exhaust
and evaporative emissions standards. Locate the emis-
sions compliance decal on the engine to determine appli-
cable standards. See the included emissions warranty for
emissions warranty information. Follow the maintenance
specifications in this manual to ensure the engine com-
plies with applicable emissions standards for the duration
of the product’s life.
This generator is certified to operate on liquid propane
vapor fuel or pipeline natural gas.
The Emission Control System code is EM (Engine Modifi-
cation). The Emission Control System on this generator
consists of the following:
Fuel Requirements
A DANGER
Explosion and Fire. Fuel and vapors are extremely
4 flammable and explosive. Add fuel in a well
ventilated area. Keep fire and spark away. Failure
to do so will result in death or serious injury: (000105)
The engine has been fitted with a dual fuel carburetion
system. The unit will run on NG or LP gas (vapor), but
has been factory-configured to run on NG. The fuel sys-
tem will be configured for the available fuel source during
installation.
Recommended fuels should have a BTU content of at
least 1,000 BTUs per ft3 (37.26 megajoules per m3) for
natural gas, or at least 2,500 BTUs per ft (93.15 mega-
joules per m3) for LP gas.
NOTE: If converting to LP gas from NG, a minimum LP
tank size of 250 gal (946 L) is recommended. See instal-
lation manual for complete procedures and details.
Battery Requirements
12 volts, Group 26R Wet Cell 540CCA minimum or
Group 35 AGM 650CCA minimum (not included with
unit). See Battery Maintenance for correct battery main-
tenance procedures.
Battery Charger
The battery charger is integrated into the control panel
module in all models. It operates as a smart charger, ver-
ifying output charging levels are safe and continuously
optimized to promote maximum battery life. A kit is pro-
vided to install a fuse in transfer switch for T1 battery
charger connection. Follow installation instructions pro-
vided with kit.
NOTE: Do not use external battery chargers.
Engine Oil Requirements
See Engine Oil Requirements for correct oil viscosity.
Section 3: Operation
Site Prep Verification
A DANGER
Automatic start-up. Disconnect utility power and
render unit inoperable before working on unit.
Failure to do so will result in death or serious injury.
(000191)
Generator must be installed to allow unimpeded airflow
into and out of generator.
Mechanical and gravity outdoor air intake openings for air
distribution and supply systems must be located not less
than 10 ft (3.05 m) horizontally from generator enclosure.
See Section 401.4 in the ICC Mechanical Code for addi-
tional information.
Verify all shrubs or tall grasses within 3 ft (0.91 m) of
intake and discharge louvers on the sides of the enclo-
sure have been removed. Install generator on high
ground where water levels will not rise and endanger it.
This unit must not operate in or be subjected to standing
water. Verify all potential water sources such as water
sprinklers, roof run-off, rain gutter downspouts, and sump
pump discharges are directed away from unit.
Generator Enclosure
Enclosure lid is locked prior to shipment. A set of keys is
attached to cardboard on top of generator. An additional
set of keys is attached to pallet bracket on the front intake
end of generator.
NOTE: Keys provided with this unit are intended for ser-
vice personnel use only.
