Standby Generator Sets Important Safety Instructions WARNING: GENERAL HAZARDS • For safety reasons, the manufacturer recommends that this equipment be installed, serviced and repaired by an Authorized Service Dealer or other competent, qualified electrician or installation technician who is familiar with applicable codes, standards and regulations. The operator also must comply with all such codes, standards and regulations.
Standby Generator Sets Important Safety Instructions • Generators installed with an automatic transfer switch will crank and start automatically when normal (utility) source voltage is removed or is below an acceptable preset level. To prevent such automatic start-up and possible injury to personnel, disable the generator’s automatic start circuit (battery cables, etc.) before working on or around the unit. Then, place a “Do Not Operate” tag on the generator control panel and on the transfer switch.

Thank you for purchasing this model of the standby generator set product line. Every effort was expended to make sure that the information and instructions in this manual were both accurate and current at the time the manual was written.
Standby Generator Sets General Information IDENTIFICATION RECORD NOTE: For actual information related to this particular model, please refer to the Manual Drawing Listing located at the end of this manual, or to the data label affixed to the unit. DATA LABEL Every generator set has a DATA LABEL that contains important information pertinent to the generator.
Standby Generator Sets Equipment Description EQUIPMENT DESCRIPTION COOLANT RECOMMENDATIONS This equipment is a revolving field, alternating current generator set. It is powered by a gaseous fueled engine operating at 1800 rpm for 4-pole direct drive units, 3600 rpm for 2-pole direct drive units and 2300 - 3000 rpm for quiet drive gear units. See the Specifications section for exact numbers.
Standby Generator Sets Engine Protective Devices ENGINE PROTECTIVE DEVICES OVERCRANK SHUTDOWN The standby generator may be required to operate for long periods of time without an operator on hand to monitor such engine conditions as coolant temperature, oil pressure or rpm.
Standby Generator Sets Fuel Systems FUEL SYSTEM PROPANE VAPOR WITHDRAWAL FUEL SYSTEM FUEL REQUIREMENTS This type of system utilizes the vapors formed above the liquid fuel in the supply tank. Approximately 10 to 20 percent of the tank capacity is needed for fuel expansion from the liquid to the vapor state. The vapor withdrawal system is generally best suited for smaller engines that require less fuel.

The Dip switch inside the control panel must be in the LP or NG position when switching to different fuels. For cold climates, optional cold weather kit (part number 0F6148) is recommended. The kit includes: • Battery Warmer • 4” Junction Box with hardware • 6 qt. pack 5W-30 synthetic oil (engine) Figure 6.
Standby Generator Sets General Information GENERATOR AC LEAD CONNECTIONS ALTERNATOR POWER WINDING CONNECTIONS See “Voltage Codes”. This generator may be rated at any one of three voltages, either single-phase or three-phase. The electrical wires in the unit’s AC connection (lower) panel should be installed according to the number of leads and the voltage/phase required for the application. If there are any questions regarding lead connection, refer to the wiring diagrams at the back of this manual.
Standby Generator Sets Installation PRIOR TO INITIAL START-UP INSTALLATION Refer to the separate “Installation Guide QT Product Line” supplied with the unit. to initially starting the generator, it must Prior be properly prepared for use. Any attempt to PREPARATION BEFORE START-UP The instructions in this section assume that the standby generator has been properly installed, serviced, tested, adjusted and otherwise prepared for use by a competent, qualified installation contractor.
Standby Generator Sets Installation START-UP CHECKLIST • Check voltage at the generator terminals. • For 3-phase units, check phase rotation at the transfer switch terminals. The generator phase rotation must match the utility phase rotation. • Check for coolant, fuel, oil, and exhaust leaks. • Close the generators main line circuit breaker. • Turn the generator set off. • Connect the UTILITY supply to the transfer switch. • Set the AUTO/OFF/MANUAL switch to AUTO.
Standby Generator Sets Operation GENERATOR CONTROL AND OPERATION not crank the engine continuously for longer Do than 30 seconds, or the heat may Refer to the appropriate control panel operator’s manual for this unit. • • OPERATING UNIT WITH MANUAL TRANSFER SWITCH If the generator was installed in conjunction with a transfer switch capable of manual operation only, the following procedure applies.
Standby Generator Sets Maintenance MAINTENANCE PERFORMED BY AUTHORIZED SERVICE FACILITIES exhaust system parts from this product get The extremely hot and remain hot after shutdown. High grass, weeds, brush, leaves, etc. must remain clear of the exhaust. Such materials may ignite and burn from the heat of the exhaust system. working on the generator, ensure the fol Before lowing: • The AUTO/OFF/MANUAL switch is in the OFF position. • The 15A fuse has been removed from the control box.
Standby Generator Sets Maintenance ENGINE COOLANT CHECK FAN BELT Check coolant level in coolant recovery bottle. See the “Specifications” section. • Inspect fan belts every three months. Replace any damaged, deteriorated, worn or otherwise defective belt. • Check fan belt tension. Thumb pressure, exerted midway between pulleys, should deflect about 3/8 to 5/8 inch. Adjust belt tension as required. • Add recommended coolant mixture as necessary.
Standby Generator Sets Maintenance COOLANT CHANGE 7. Start engine and check for oil leaks. Every year, have an Authorized Service Facility drain, flush and refill the cooling system. See the “Specifications” section for cooling system recommendations. Figure 10.2 - Oil Filter MISCELLANEOUS MAINTENANCE CLEANING THE GENERATOR Keep the generator as clean and as dry as possible. Dirt and moisture that accumulates on internal generator windings have an adverse effect on insulation resistance.
Standby Generator Sets Maintenance BATTERY MAINTENANCE The battery should be inspected per the “Service Schedule” section. The following procedure should be followed for inspection: sure the AUTO/OFF/MANUAL switch is set to Be the OFF position before connecting the battery cables. If the switch is set to AUTO or MANUAL, the generator can crank and start as soon as the battery cables are connected. 1. Inspect the battery posts and cables for tightness and corrosion. Tighten and clean as necessary. 2.
Standby Generator Sets Service Schedule SERVICE SCHEDULE 30 KW - 150 KW STANDBY GAS ENGINE DRIVEN GENERATOR SETS The following is a recommended maintenance schedule for standby gas engine driven generator sets from 30kW to 150 kW in size. The established intervals in the schedule are the maximum recommended when the unit is used in an average service application. They will need to be decreased (performed more frequently) if the unit is used in a severe application.
