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 Identification Code DATA LABEL Use this code to obtain important information about the generator. For example, if the code is: Every generator set has a DATA LABEL that contains important information pertinent to the generator. The data label, which can be found attached to the generator’s lower connection box, lists the unit’s serial number and its rated voltage, amps, wattage capacity, phase, frequency, rpm, power factor, etc.
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 OIL PRESSURE SENSING ENGINE PROTECTIVE DEVICES 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.

Standby Generator Sets Specifications 5.4L & 6.8L IGNITION DESCRIPTION NOTE: This single-fire Ignition is intended to operate with a 10-cylinder, 6.8L engine and an 8-cylinder, 5.4L engine. The ignition cover does not need to be removed to see the LED. The 6.8L engine uses a 40-1 crank sensor, a magpickup CAM sensor and individual coil-on-plug coils for each spark-plug.
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. Before working on the generator, ensure the following: • 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 7. Start engine and check for oil leaks. 2. Remove the spark plugs and check the condition. Replace the spark plugs if worn or if reuse is questionable. See the “Service Schedule” section for recommended inspection. 3. Check the spark plug gap using a wire feeler gauge. Adjust the gap to 1.14 mm (0.045 inch) by carefully bending the ground electrode (Figure 10.4). Figure 10.2 - Oil Filter Oil Fill Oil Dipstick Figure 10.
Standby Generator Sets Maintenance BATTERY electrolyte fluid is an extremely caus Battery tic sulfuric acid solution that can cause severe All lead-acid storage batteries discharge when not in use. Refer to specific instructions and warnings that accompany the battery. If such information is not available, observe the following precautions when handling a battery: burns. Do not permit fluid to contact eyes, skin, clothing, painted surfaces, etc.
