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.
Standby Generator Sets Important Safety Instructions INTRODUCTION This symbol points out potential fire hazard. symbol points out potential electrical shock This hazard. 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 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.

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 COOLING SYSTEM Air intake and outlet openings in the generator compartment must be open and unobstructed for continued proper operation. This includes such obstructions as high grass, weeds, brush, leaves and snow. working on the generator, ensure the fol Before lowing: Without sufficient cooling and ventilating air flow, the engine/generator quickly overheats, which causes it to shut down.
Standby Generator Sets Maintenance EXERCISE SYSTEM Figure 10.1 - Oil Dipstick and Oil Fill Cap Start the generator engine at least once every seven days and let it run at least 20 minutes. See “Weekly Exercise Cycle”. OIL FILL CAP OIL DIPSTICK INSPECT COOLING SYSTEM • Inspect engine cooling system. See “Maintenance Schedule”. • Check hoses for damage, deterioration, leaks, etc. Correct any discrepancies found. • Check hose clamps for tightness.
Standby Generator Sets Maintenance CHANGING ENGINE OIL Figure 10.3 – Engine Air Cleaner Refer to maintenance performed by authorized service facilities for engine oil and filter change frequencies. Air Cleaner Drain the oil while the engine is still warm from running. This means warm up the engine, shut it down and drain immediately as follows: 1. Remove OIL DRAIN HOSE from its retaining clip. 2. Loosen and remove OIL DRAIN HOSE CAP. Drain oil completely into suitable container. 3.
Standby Generator Sets Maintenance MISCELLANEOUS MAINTENANCE 2. Check the battery fluid level of unsealed batteries and, if necessary, fill with DISTILLED WATER ONLY. DO NOT USE TAP WATER IN BATTERIES. 3. Have the state of charge and condition checked. This should be done with an automotive-type battery hydrometer. 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 Service Schedule SERVICE SCHEDULE The following is a recommended maintenance schedule for small standby and residential generator sets. 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.
