“240VUtility”leadsmustberoutedinconduit.The
“240VUtility”leadsdeliverpowertothegenerator’scircuit
board, optional battery warmer and optional oil warmer. This
power also charges the battery. When power on these leads
is lost, the generator will start.
Using provided 2 pole connector plug and installer-supplied
minimum 300V, 14 AWG copper wire, connect each control
circuit terminal in the generator to the two-amp fuse
terminals in the automatic transfer switch.
Fault Detection System
The generator may have to run for long periods of time with
no operator present. For that reason, the system is equipped
with sensors that automatically shut down the generator in
the event of potentially damaging conditions, such as low
oil pressure, high oil temperature, over speed, and other
conditions. Refer to Fault Detection System in the Operator’s
Manual for more detailed information.
The owner will use the remote LED indicator to observe the
status of the home generator system. Consult with the owner
for a convenient location. To install the remote LED indicator:
1. Push the LED through the mounting plate from the
front until it snaps in place.
IMPORTANT: The LED is polarity sensitive.
2. Using provided 10 pole connector and installer-supplied
minimum 18 AWG wire, connect the remote LED to the
generator control board. Use wire nuts to attach wire to
LED leads.
3. Attach mounting plate to installer-supplied electrical
box.

System Control Panel
The home generator control panel, located inside the
generator housing, is shown below.
Brief descriptions of the controls used during installation are:
A - Set Exercise Switch — Used to set the exercise cycle.
B - System Switch — Switches modes to OFF and AUTO.
C - 15 Amp Fuse — Protects the DC control circuits.
D - Digital Display — Displays running time and fault codes.
E - Circuit Breaker — Must be ON to supply power to the
transfer switch.
F - Manual Over-Ride Switch — Turns generator ON or OFF.
More information may be found in Controls in the Operator’s
Manual.
System Switch
This two-position switch is the most important control on
the home generator and is used as follows:
 • AUTO”positionisthenormaloperatingposition.If
a utility power outage is sensed, the system will start
the generator. When utility power is restored, lets the
engine stabilize internal temperatures, shuts off the
generator, and waits for the next utility power outage.
 • OFF”positionturnsoffrunninggenerator,prevents
unit from starting and resets any detected faults.
15 Amp Fuse
Protects the home generator DC control circuits. If the fuse
has ‘blown’ (melted open) or was removed, the engine
cannot crank or start. Replace the fuse using only an
identical ATO 15A fuse. One spare fuse is supplied with the
unit.
Final Installation Considerations
Engine Oil
NOTICE
Any attempt to crank or start the engine before it has been
properly serviced with the recommended oil will result in
equipment failure.
Refer to • Maintenance and engine manual for oil fill
information.
Damage to equipment resulting from failure to follow this •
instruction will void engine and generator warranty.
This engine is shipped from the factory pre-run and filled
with synthetic oil (API SJ/CF 5W-30W). This allows for
system operation in the widest range of temperature and
climate conditions. Before starting the engine, check oil level
and ensure that engine is serviced as described in the engine
operator’s manual.
NOTE: The use of synthetic oil does not alter the required oil
change intervals described in the engine operator’s manual.
Battery
The home generator is supplied with a sealed, valve-
regulated, lead-acid rechargeable 12 Volt DC, AGM type,
55 Amp-Hour battery. The battery cables are connected
at the factory. The unit’s 15 Amp fuse, which isolates
the battery and prevents the unit from starting, has been
removed for shipping. The battery will lose some charge
prior to installation of the generator. If battery voltage
is below 12 Volts, charge the battery. See Battery in the
Operator’s Manual Maintenance section for details.
IMPORTANT: If battery voltage is below 5 Volts, it may not
take a charge and you will need a new battery.
Fuel Supply System
Ensure that all fuel pipe connections are tight, secure and
without leaks.
Ensure that all gas line shutoff valves are OPEN and that
adequate fuel pressure is available whenever automatic
operation is desired.

Initial Start-up (No Load)
Before operating the home generator or placing it into
service, inspect the entire installation carefully.
Then begin testing the system without any electrical loads
connected, as follows:
1. Set generator’s main circuit breaker to its ON (closed)
position.
2. Install 15 Amp fuse in control panel.
3. Set generator’s system switch to AUTO.
4. Push MANUAL OVER-RIDE button on control panel.
NOTE: When the home generator is started for the very
first time, it will require that air in the gaseous fuel lines be
purged. This may take a few minutes.
5. DO NOT crank engine for more than 10 seconds, then
pause for 10 seconds to reduce heat in the starter.
6. Repeat process until engine starts.
7. Listen for unusual noises, vibration or other indications
of abnormal operation. Check for oil leaks while engine
runs.
8. Let engine warm up for about five minutes to allow
internal temperatures to stabilize.
9. Connect an accurate AC voltmeter and a frequency
meter to check generator output at load side of circuit
breaker. Voltage should be 239-262 Volts, frequency
should be 62.0 - 62.5 Hz.
NOTE: If either parameter is outside these ranges, perform
the Engine Adjustments described below.
10. Check generator output between one of the generator
connection lugs and the neutral lug, then between the
other generator connection lug and the neutral lug.
In both cases, voltage reading should be between
119-131 Volts.
11. Push and hold MANUAL OVER-RIDE button on control
panel again until engine stops.
IMPORTANT: DO NOT proceed until you are certain that
generator AC voltage and frequency are correct and within
the stated limits. To obtain the proper generator frequency,
see Engine Adjustments.
Engine Adjustment
Each home generator unit leaves the factory set for either
NG or LP gas operation. There are regional variances in the
composition of natural gas. If the generator output voltage
or frequency measured during Initial Start-Up (paragraph #9)
is outside the listed ranges, the combustibility of the gas
supplied at the installation site may be substantially different
from the fuel used at the factory.
To adjust the engine for this difference, proceed as follows.
1. Open the oil drain and control panel access doors.
2. Remove the four screws that hold the circuit breaker
cover to the air intake guard.
3. Connect an accurate frequency meter to the line
side of the generator’s main circuit breaker.
4. Ensure that the 15 Amp fuse is installed.
5. Set the generator’s main circuit breaker ON.
6. Set the generator’s system switch to AUTO.
7. Push MANUAL OVER-RIDE button on control panel.
When the engine starts, allow it to warm up for five
minutes.
8. Normal no load frequency is 62.0 to 62.5 Hz. If
adjustment is needed at no load, slowly rotate the
governor adjustment screw (A) clockwise and/or
counterclockwise until frequency is 62.0 to 62.5 Hz.

9. Push and hold MANUAL OVER-RIDE button on control
panel again until engine stops.
10. Turn the service disconnect to the transfer switch off.
After a short time delay, the transfer switch will connect
to the generator.
11. Load generator to full load.
12. Connect an accurate frequency meter to the load side of
the generator’s main circuit breaker. Frequency should
be above 57.0 Hz.
13. If frequency is below 57.0 Hz, slowly rotate the
governor adjustment nut or screw clockwise and/or
counterclockwise until frequency is above 57.0 Hz.
14. Turn the service disconnect to the transfer switch on.
The transfer switch will connect to the utility after five
minutes.
15. After the engine has stopped running,
• Ifanadjustmentwasmadeinstep13,repeatsteps
3 through 9.
• Ifanadjustmentwasnotmadeinstep13,proceed
to step 16.
IMPORTANT: If the no load frequency falls out of the no
load parameter after full load adjustment is made, contact an
authorized service center.
16. Reinstall the circuit breaker cover to the air intake
guard.
17. Close the oil drain and control panel access doors.
Controls
See the Operator’s Manual for complete description of the
home generator controls.
Operation
Automatic Operation Sequence
The generator’s control panel houses a logic control circuit
board. This control board constantly monitors utility power
source voltage. Should that voltage drop below a preset
level, control board action will signal the engine to crank and
start.
When utility source voltage is restored above a preset
voltage level, the engine is signaled to shut down.
The actual system operation is not adjustable and is
sequenced by sensors and timers on the control board, as
follows:
Utility Voltage Dropout Sensor
 • Thissensormonitorsutilitysourcevoltage.
 • Ifutilitysourcevoltagedropsbelowabout70percent
of the nominal supply voltage, the sensor energizes a
10 second timer. The timer is used to ‘sense’ brown-
outs.
 • Oncethetimerhasexpired,theenginewillcrankand
start.
Utility Voltage Pickup Sensor
This sensor monitors utility power supply voltage. When that
voltage is restored above 80 percent of the nominal source
voltage, a time delay starts timing and the engine will go to
engine cool-down.
Engine Cool-down Timer
 • Whentheloadistransferredbacktotheutilitypower
source, the engine cool-down timer starts timing.
 • Thetimerwillrunforaboutoneminute,thenthe

Setting Exercise Timer
The home generator is equipped with an exercise timer that
will start and exercise the system once every seven days.
During this exercise period, the unit runs for approximately
20 minutes and then shuts down. Electrical load transfer
DOES NOT occur during the exercise cycle (unless an utility
power outage occurs).
Abuttononthecontrolpanelislabeled“SetExercise”(see
System Control Panel). The specific day and the specific
time of day this button is pressed is programmed into the
control board memory. This date and time is then used to
automatically initiate the system exercise cycle. The “SET
EXERCISE”legendonthecontrolpanelwillflashuntiltheset
exercise cycle is set.
To perform the Set Exercise procedure:
1. Choose the day and time you want your home
generator to exercise.
2. On that day and time, press and hold down the “Set
Exercise”buttonforthreeseconds.
NOTE:“SETEXERCISE”willflashuntilthebuttonispressed
forthreeseconds,then“SETEXERCISE”willilluminatefor
5 seconds, and finally turn off.
Forexample,ifyoupressthe“SetExercise”buttonon
Sunday morning at 10:00 AM, the unit will run an exercise
cycle the following Sunday at 10:00 AM (+/- 1/2 hour).
NOTE:“SetExercise”willonlyworkiftheunitisinthe
Automatic mode and this exact procedure is followed.
The exerciser will need to be re-set if the 15 Amp fuse
is removed or changed, or if the 12 Volt DC battery is
disconnected.
If you want to change the day and time the unit exercises,
simplyperformthe“SetExercise”procedureattheexact
weekday and time you want it to take place.
