2 Generac ® Pow er Systems, Inc. Study these SAFETY RULES carefully before installing, operating or servicing this equipment. Become familiar with this Owner’s Manual and with the unit. The generator can operate safely , efficiently and reliably only if it is properly installed, operated and maintained.
Generac ® Pow er Systems, Inc. 3 ELE CTR ICAL HA Z AR DS • All generators covered by this manual produce dangerous electrical voltages and 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 opera- tion.
Only qualified electricians or contractors should attempt such installations, which must comply strictly with applicable codes, standards and regulations.

Generac ® Pow er Systems, Inc. 7 1.6 S Y S TEM SE T LED The “System Set ” LED is lit when all of the following conditions are true: 1. The A UTO/OFF/MANU AL switch is set to the A UTO position. 2. The utility voltage being supplied to the unit is being sensed by the PCB.
NOTE: The natural gas adjustment screw is preset during installation and should not need any further adjustment. 1.9.2 1 2KW AN D 1 5KW , 990CC ENGIN ES T o reconfigure the fuel system from NG to LP , follow these steps: NOTE: The primary regulator for the propane supply is NOT INCL UDED with the generator .
Generac ® Pow er Systems, Inc. 9 • Install the transfer switch indoors on a firm, stur- dy supporting structure. • T o prevent switch distortion, level the switch if nec- essary . This can be done by placing washers between the switch enclosure and mounting sur- face.
10 Generac ® Pow er Systems, Inc. Do not open or mutilate the battery . Released electrolyte has been known to be harmful to the skin and eyes, and to be toxic. The electrolyte is a dilute sulfuric acid that is harmful to the skin and eyes. It is electrically conductive and corrosive.
Generac ® Pow er Systems, Inc. 11 7. When certain that utility supply voltage is com- patible with transfer switch and load circuit rat- ings, turn OFF the utility power supply to the transfer switch. 8. On the generator panel, set the A UTO/OFF/ MANU AL switch to MANU AL.
12 Generac ® Pow er Systems, Inc. 5. T urn ON the utility power supply to the transfer switch, using the means provided (such as a util- ity main line circuit breaker). 6. Set the A UTO/OFF/MANU AL switch to AUTO . The system is now ready for automatic operation.
