monoxide can cause dizziness, throbbing temples, nausea, muscular twitching, headache, vomiting, weakness,
sleepiness, inability to think clearly, fainting, unconsciousness or even death.
A CAUTION!
The control panel for this unit is intended to be operated by qualified service personnel only.
1.2 mGeneral Safety Hazards
• For safety reasons, this equipment should only be installed, serviced and repaired by a Service Dealer or other competent, qualified electri-
cian or installation technician who is familiar with applicable codes, standards, regulations and product Installation Manual guidelines. The
operator also must comply with all such codes, standards, regulations and product installation Manual guidelines.
• The engine exhaust fumes contain carbon monoxide, which can be DEADLY.This dangerous gas, if breathed in sufficient concentrations, can
cause unconsciousness or even death. DO NOT alter or add to the exhaust system or do anything that might render the system unsafe or in
noncompliance with applicable codes and standards.
• Install a carbon monoxide alarm indoors, according to manufacturer's instructions/recommendations.
• Adequate, unobstructed flow of cooling and ventilating air is critical for correct generator operation. Do not alter the installation or permit even
partial blockage of ventilation provisions, as this can seriously affect safe operation of the generator. The generator MUST be installed and
operated outdoors only.
• Keep hands, feet, clothing, etc. away from drive belts, fans, and other moving or hot parts. Never remove any drive belt or fan guard while the
unit is operating.

1.3 mExhaust Hazards
Generator engine exhaust contains DEADLY carbon monoxide, an odorless, colorless, poisonous gas. Breathing carbon monoxide can
cause dizziness, throbbing temples, nausea, muscular twitching, headache, vomiting, weakness, sleepiness, inability to think clearly, fainting,
unconsciousness or even death. Ifany carbon monoxide poisoning symptom is experienced, move into fresh air and immediately seek med-
ical attention.
This generator is designed for OUTDOOR installation ONLY.Never operate the generator inside any garage or other enclosed space.
1.4 mElectrical Hazards
All generators covered by this manual produce dangerous electrical voltages that can cause fatal electrical shock. Utility power delivers
extremely high and dangerous voltages to the transfer switch, as does the standby generator when it is in operation. Avoid contact with bare
wires, terminals, connections, etc. while the unit is running. Ensure all appropriate covers, guards and barriers are in place, secured and/or
locked before operating the generator. Ifwork must be done around an operating unit, stand on an insulated, dry surface to reduce potential
shock hazard.

• This is an Automatic Standby Generator, the generator may crank and start at any time when utility is lost. When this occurs, load circuits are
transferred to the STANDBY (generator) power source. To prevent injury,before working on this generator (for inspection, service or mainte-
nance), always put the generator into the OFF mode and remove the 7.5 Amp fuse from the generator control panel.
• In case of accident caused by electric shock, immediately shut down the source of electrical power, if this is not possible, attempt to free the
victim from the live conductor. AVOID DIRECT CONTACTWITH THE VICTIM. Use a nonconducting implement, such asa dry rope or board,
to free the victim from the live conductor, if the victim is unconscious, apply first aid and get immediate medical help.
• Never wear jewelry when working on this equipment. Jewelry can conduct electricity resulting in electric shock, or may get caught in moving
components resulting in injury.
1.5 Fire Hazards
• For fire safety,the generator must be installed and maintained properly, installation MUST always comply with applicable codes, standards,
laws, regulations and product installation Manual guidelines. Adhere strictly to local, state, and national electrical and building codes. Comply
with regulations the Occupational Safety and Health Administration (OSHA) has established. Also, ensure that the generator is installed in
accordance with the manufacturer's instructions and recommendations. Following proper installation, do nothing that mightalter asafe instal-
lation and render the unit in noncompliance with the aforementioned codes, standards, laws and regulations.
• Keep afire extinguisher near the generator at all times. Extinguishers rated "ABC" by the National Fire Protection Association are appropriate
for use on the standby generator. Keepthe extinguisher properly charged and befamiliar with its use. Consult the local fire department with
any questions pertaining to fire extinguishers.
1.6 Explosion Hazards
• Do not smoke around the generator. Wipe up any fuel or oil spills immediately. Ensure that no combustible materials are left in the generator
compartment, or on or near the generator as FIRE or EXPLOSION may result. Keepthe area surrounding the generator clean and free from
debris.
• Gaseous fluids such as natural gas and liquid propane (LP) gas are extremely EXPLOSIVE. install the fuel supply system according to appli-
cable fuel-gas codes. Before placing the home standby electric system into service, fuel system lines must be properly purged and leak
tested according to applicable code. After installation, inspect the fuel system periodically for leaks. No leakage can be permitted.
Automatic Standby Generator Owner's Manual 3

Ifthis generator is used to power electrical load circuits normally powered by a utility powersource, it is
required by code to install a transfer switch. The transfer switch must effectively isolatethe electrical system
from the utility distribution system when the generator is operating (NEC 702). Failure to isolate an electrical
system by such means will result in damage to the generator and also may result in injury or death to utility
powerworkers due to backfeed of electrical energy.

4. Set the Main Circuit Breaker (Generator Disconnect) to its ON (Closed) position.
With these steps complete, the generator willstart automatically when utility source voltage drops below a preset level.After the unit starts, loads
are transferred to the standby power source.
3.4.1m Automatic Sequence of Operation
3.4.1.1 mUtility Failure
With the generator set toAUTO, when the utility fails (below 65% of nominal) a 10second (optionally programmable) line interrupt delay time is
started. Ifthe utility isstill gone when the timer expires, the engine will crank and start. Once started, a 5 second engine warm-up timer will be ini-
tiated. When the warm-up time expires, the controller will transfer the load to the generator. Ifthe utility power is restored (above 75% nominal) at
any time from the initiation of the engine start until the generator is ready to accept load (5 second warm-up time has not elapsed), the controller
will complete the start cycle and run the generator through its normal cool down cycle, however, the load will remain on the utility source.
3.4.1.2 m Cranking
The system will control the cyclic cranking as follows:
8kW unit- 5 cranking cycles as follows: 15 second crank, seven (7) second rest,followed by four (4) additional cycles of seven (7) second
cranks followed byseven (7) second rests.
11-20kW units - 5 cranking cycles asfollows: 16second crank, seven (7) second rest, 16 second crank, seven (7) second rest,followed by
three (3) additional cycles of seven (7) second cranks followed by seven (7) second rests.

EXERCISE
• Will not transfer to generator if utility is present
• Wilt transfer to generator if utility fails (below 65% of nominal for 10 consecutive seconds)
• Wilt transfer back when utility returns for 15 consecutive seconds The engine will continue to run
until removed from the MANUAL mode
• Will start and run if utility fails for 10 consecutive seconds (factory default)
• Will start a 5 second engine warm-up timer
•Wilt not transfer if utility subsequently returns
•Wilt transfer to generator if utility is not present
• Will transfer back to utility once utility returns (above 75% of nominal) for 15 seconds
• Will not transfer back to utility unless utility returns The generator will shut down if the OFF button is
pressed or a shutdown alarm is present
• Once utility power is returned, the generator will shut down after 1 minute cool-down time
• Wilt not exercise if generator is already running in either AUTO or MANUAL mode
• During exercise, the controller will only transfer if utility fails during exercise for 10 seconds, and will
switch to AUTO

3.6 mManual Transfer Operation
DO NOT attempt to activate the transfer switch manually until all powervoltage supplies to the switch have been
completely turned off. Failureto turn off all powervoltage supplies may result in extremely hazardous and possi-
bly fatal electrical shock.
Prior to automatic operation, manually exercise the transfer switch to verify that there is no interference with proper operation of the mechanism.
Manual operation of the transfer switch is required if electronic operation should fail.
