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. Many accidents are caused by failing to follow simple and fundamental rules or precautions. Bryant cannot anticipate every possible circumstance that might involve a hazard. The warnings in this manual, and on tags and decals affixed to the unit are, therefore, not all-inclusive. If using a procedure, work method or operating technique that Bryant does not specifically recommend, ensure that it is safe for others. Also make sure the procedure, work method or operating technique utilized does not render the generator unsafe. DANGER ! Despite the safe design of this generator, operating this equipment imprudently, neglecting its maintenance or being careless can cause possible injury or death. Permit only responsible and capable persons to install, operate or maintain this equipment. Potentially lethal voltages are generated by these machines. Ensure all steps are taken to render the machine safe before attempting to work on the generator. ! Parts of the generator are rotating and/or hot during operation. Exercise care near running generators. ! GENERAL HAZARDS ! • For safety reasons, Bryant recommends that this equipment be installed, serviced and repaired by a Bryant 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. 2 Bryant ! ! • Installation, operation, servicing and repair of this (and related) equipment must always comply with applicable codes, standards, laws and regulations. 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, operated and serviced in accordance with the manufacturer’s instructions and recommendations. Following installation, do nothing that might render the unit unsafe or in noncompliance with the aforementioned codes, standards, laws and regulations. • The engine exhaust fumes contain carbon monoxide gas, which can be DEADLY. This dangerous gas, if breathed in sufficient concentrations, can cause unconsciousness or even death. For that reason, adequate ventilation must be provided. Exhaust gases must be piped safely away from any building or enclosure that houses the generator to an area where people, animals, etc., will not be harmed. This exhaust system must be installed properly, in strict compliance with applicable codes and standards. • 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. • Adequate, unobstructed flow of cooling and ventilating air is critical to prevent buildup of explosive gases and to ensure 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. • Keep the area around the generator clean and uncluttered. Remove any materials that could become hazardous. • When working on this equipment, remain alert at all times. Never work on the equipment when physically or mentally fatigued. • Inspect the generator regularly, and promptly repair or replace all worn, damaged or defective parts using only factory-approved parts. • Before performing any maintenance on the generator, disconnect its battery cables to prevent accidental start-up. Disconnect the cable from the battery post indicated by a NEGATIVE, NEG or (–) first. Reconnect that cable last. • Never use the generator or any of its parts as a step. Stepping on the unit can stress and break parts, and may result in dangerous operating conditions from leaking exhaust gases, fuel leakage, oil leakage, etc. ELECTRICAL HAZARDS • 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 well as the standby generator. Avoid contact with bare wires, terminals, connections, etc., on the generator as well as the transfer switch, if applicable. Ensure all appropriate covers, guards and barriers are in IMPORTANT SAFETY INSTRUCTIONS Bryant Liquid-cooled 15 kW Generators • • • • • • • • • place before operating the generator. If work must be done around an operating unit, stand on an insulated, dry surface to reduce shock hazard. Do not handle any kind of electrical device while standing in water, while barefoot, or while hands or feet are wet. DANGEROUS ELECTRICAL SHOCK MAY RESULT. If people must stand on metal or concrete while installing, operating, servicing, adjusting or repairing this equipment, place insulative mats over a dry wooden platform. Work on the equipment only while standing on such insulative mats. The National Electrical Code (NEC), Article 250 requires the frame and external electrically conductive parts of the generator to be connected to an approved earth ground and/or grounding rods. This grounding will help prevent dangerous electrical shock that might be caused by a ground fault condition in the generator set or by static electricity. Never disconnect the ground wire. Wire gauge sizes of electrical wiring, cables and cord sets must be adequate to handle the maximum electrical current (ampacity) to which they will be subjected. Before installing or servicing this (and related) equipment, make sure that all power voltage supplies are positively turned off at their source. Failure to do so will result in hazardous and possibly fatal electrical shock. Connecting this unit to an electrical system normally supplied by an electric utility shall be by means of a transfer switch so as to isolate the generator electric system from the electric utility distribution system when the generator is operating. Failure to isolate the two electric system power sources from each other by such means will result in damage to the generator and may also result in injury or death to utility power workers due to backfeed of electrical energy. 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. 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 CONTACT WITH THE VICTIM. Use a nonconducting implement, such as a 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 causing injury. FIRE HAZARDS • Keep a fire extinguisher near the generator at all times. Do NOT use any carbon tetra-chloride type extinguisher. Its fumes are toxic, and the liquid can deteriorate wiring insulation. Keep the extinguisher properly charged and be familiar with its use. Consult the local fire department for any questions pertaining to fire extinguishers. EXPLOSION HAZARDS • Properly ventilate any room or building housing the generator to prevent build-up of explosive gas. • 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. Keep the area surrounding the generator clean and free from debris. • Bryant generator sets may operate using one of several types of fuels. All fuel types are potentially FLAMMABLE and/or EXPLOSIVE and should be handled with care. Comply with all laws regulating the storage and handling of fuels. Inspect the unit’s fuel system frequently and correct any leaks immediately. Fuel supply lines must be properly installed, purged and leak tested according to applicable fuel-gas codes before placing this equipment into service. • Diesel fuels are highly FLAMMABLE. Gaseous fluids such as natural gas and liquid propane (LP) gas are extremely EXPLOSIVE. Natural gas is lighter than air, and LP gas is heavier than air. Install leak detectors accordingly.

Bryant 3 Section 1 - General Information Bryant Liquid-cooled 15 kW Generators 1.1 GENERATOR 1.3 This equipment is a liquid-cooled, engine-driven generator set. The generator is designed to supply electrical power that operates critical electrical loads during utility power failure. The unit has been factory-installed in a weather resistant, all metal enclosure and is intended for outdoor installation only. Use this generator as a source of electrical power for the operation of 120 and/or 240 volts, single phase loads. These models are available. They are rated as follows: Model ASPAS1BBL015: Provides 15,000 watts (15 kW) of single phase power. AUTOMATIC SYSTEM OPERATION When this generator, along with its transfer switch, has been installed and interconnected, a circuit board in the generator panel constantly monitors UTILITY power source voltage. Should that voltage drop below a preset value, and remain at such a low state for a preset amount of time, the generator cranks and starts. After the generator starts, the transfer switch transfers load circuits so the generator can power them. When UTILITY source voltage has been restored, the switch re-transfers back to the utility source voltage and the generator then shuts down. Please reference the transfer switch manual for specific information. ! 1.2 If this generator is used to power electrical load circuits normally powered by a UTILITY power source, it is required by code to install a transfer switch. The transfer switch must effectively isolate the electric system from the utility distribution system when the generator is operating (NEC 701). Failure to isolate an electrical system by such means results in damage to the generator and may also result in injury or even death to utility power workers due to backfeed of electrical energy. TRANSFER SWITCH This generator system includes a matched automatic transfer switch which is intended to be used in conjunction with the generator. It is supplied with a NEMA 3R enclosure. The NEMA 3R enclosure is weather proof and can be used indoors or outdoors. Follow these rules: • Install the transfer switch on a firm, sturdy supporting structure. • To prevent switch distortion, level the switch if necessary. This can be done by placing washers between the switch enclosure and the mounting surface. • Never install the switch where water or any corrosive substance might drip onto the enclosure. • Protect the switch at all times against excessive moisture, dust, dirt, lint, construction grit and corrosive vapors. • Failure to utilize a Bryant transfer switch with this generator will void the warranty. 1.4 GENERATOR AC CONNECTION SYSTEMS The generator was shipped from the factory with its stator AC output leads connected in a single-phase, three-wire generator AC connection system (Figure 1.1). The stator assembly in this system consists of a pair of stationary windings, with two leads brought out of each winding. Each single winding can supply 120 volts AC, 60 Hertz. When the two windings are connected in series, a 240 volts, 60 Hertz AC output results. Typically the two “hot” leads in the circuit are Wires No. 11 and 44. The “Neutral” leads are the junction of Wires 22 and 33. Figure 1.1 - Generator AC Connection System 1.5 MAIN CIRCUIT BREAKER The generator’s main circuit breaker is included with the unit as shipped from the factory. The breaker for each unit is described in Figure 1.2.

If propane (LP requirements) gas is preferred, refer to Section 1.12. Recommended fuels should have a Btu content of at least 1,000 Btus per cubic foot for natural gas and at least 2,520 Btus per cubic foot for LP gas. Ask the fuel supplier for the Btu content of the fuel being used. 1.7.1 LOW OIL PRESSURE SWITCH This switch is normally-closed (N.C.), but is held open by engine oil pressure during engine running. Should operating oil pressure drop below about 8-10 psi (55-68 kPa), the switch contacts close and the engine shuts down automatically (Figure 1.4). Figure 1.4 - Low Oil Pressure Switch Fuel pressure for a natural gas set up should be five inches to 14 inches of water column (0.18 to 0.5 psi) at all load ranges. Fuel pressure for an LP vapor set up should be 11 inches to 14 inches of water column (0.4 to 0.5 psi) at all load ranges. NOTE: A separate gas line and regulator may be needed to assure proper gas pressure to the generator. Improper gas pressure can cause hard starting and affect engine durability. 1.7.2 ! 1.7 Gaseous fuels such as natural and LP (propane) gas are highly explosive. Even the slightest spark can ignite such fuels and cause an explosion. No leakage of fuel is permitted. Natural gas, which is lighter than air, tends to collect in high areas. LP gas is heavier than air and tends to settle in low areas. HIGH COOLANT TEMPERATURE SWITCH This normally open (N.O.), thermostatic switch has sensing tip which is immersed in captive coolant. Should coolant temperature exceed about 230°F (110°C), the switch contacts close, which causes the engine to shut down automatically (Figure 1.5). Figure 1.5- High Coolant Temperature Switch ENGINE PROTECTIVE DEVICES The engine has several safety switches which cause the engine to automatically shut down under the following conditions: low oil pressure, high coolant temperature, engine overspeed, low coolant level or overcrank (Figure 1.3). Figure 1.3 - Engine Protective Devices 1.7.3 LOW COOLANT LEVEL SWITCH Should engine coolant level drop below the level of the high coolant temperature switch, it is possible for the engine to overheat without automatic shutdown. To prevent such overheating without automatic shut down, the engine has a low coolant level sensor. If the engine coolant drops too low, the engine automatically shuts down (Figure 1.6 on page 6).

Bryant 7 Section 2 — Installation Bryant Liquid-cooled 15 kW Generators 1.14 ENGINE OIL RECOMMENDATIONS 1.16 BEFORE INSTALLATION The unit has been filled with 15W-40 engine oil at the factory. Use a high-quality detergent oil classified “For Service SJ or latest available.” Detergent oils keep the engine cleaner and reduce carbon deposits. Use oil having the following SAE viscosity rating, based on the ambient temperature range anticipated before the next oil change: Before installing this equipment, check the ratings of both the generator and the transfer switch. Read “Emergency Isolation Method” and “Total Circuit Isolation Method” in Sections 2.5 and 2.6. Temperature Above 80° F (27° C) 32° to 80° F (-1° to 27° C) Below 32° F (0° C) Oil Grade (Recommended) SAE 30W or 15W-40 SAE 20W-20 or 15W-40 SAE 10W or 15W-40 NOTE: Synthetic oil is highly recommended when the generator will be operating in ambient temperatures which regularly exceed 90° F and/or fall below 30° F. The generator’s rated wattage/amperage capacity must be adequate to handle all electrical loads that the unit will power. The critical (essential) loads may need to be grouped together and wired into a separate “emergency” distribution panel. The standard transfer switch has no sensing or controlling circuit boards. Instead, the generator control console houses a “Printed Circuit Board Assembly”, which controls all phases of operation, including engine start up and load transfer. 2.1 STANDBY GENERATOR INSTALLATION DANGER ! Any attempt to crank or start the engine before it has been properly serviced with the recommended oil may result in an engine failure. Connecting this generator to an electrical system normally supplied by an electric utility shall be by means of a transfer switch, so as to isolate the electric system from the utility distribution system when the generator is operating. Failure to isolate the electric system by these means will result in damage to the generator and may also result in injury or death to utility workers due to backfeed of electrical energy. 1.15 COOLANT RECOMMENDATIONS Use a mixture of half low silicate ethylene glycol base anti-freeze and deionized water. Cooling system capacity is about 8 U.S. quarts (7.6 liters). Use only deionized water and only low silicate anti-freeze. If desired, add a high quality rust inhibitor to the recommended coolant mixture. When adding coolant, always add the recommended 50-50 mixture. ! Do not use any chromate base rust inhibitor with ethylene glycol base anti-freeze or chromiumhydroxide (“green slime”) forms and will cause overheating. Engines that have been operated with a chromate base rust inhibitor must be chemically cleaned before adding ethylene glycol base anti-freeze. Using any high silicate anti-freeze boosters or additives will also cause overheating. It is also recommended that any soluble oil inhibitor is NOT used for this equipment. If an open bottom is used, the engine-generator is to be installed over non-combustible materials and should be located such that combustible materials are not capable of accumulating under the generator set. Only qualified, competent installation contractors or electricians thoroughly familiar with applicable codes, standards and regulations should install this standby electric power system. The installation must comply strictly with all codes, standards and regulations pertaining to the installation. This genset must be installed on a level surface. The base frame must be level within 1/2 inch all around. ! After the system has been installed, do nothing that might render the installation in noncompliance with such codes, standards and regulations. 2.1.1 NFPA STANDARDS The following published standards booklets pertaining to standby electric systems are available form the National Fire Protection Association (NFPA), Batterymarch Park, Quincy, MA 02269: 8 Bryant Section 2 — Installation Bryant Liquid-cooled 15 kW Generators NOTE: It is essential to use the latest version of any standard to ensure correct and current information. • NFPA No. 37, STATIONARY COMBUSTION ENGINES AND GAS TURBINES. • NFPA No. 76A, ESSENTIAL ELECTRICAL SYSTEMS FOR HEALTH CARE FACILITIES. • NFPA No. 220, STANDARD TYPES OF BUILDING CONSTRUCTION • NFPA No. 68, GUIDE FOR EXPLOSION VENTING • NFPA No. 70, NATIONAL ELECTRICAL CODE. • NFPA No. 30, FLAMMABLE AND COMBUSTIBLE LIQUIDS CODE. • NFPA No. 10, INSTALLATION, MAINTENANCE AND USE OF PORTABLE FIRE EXTINGUISHERS. 2.1.2 OTHER PUBLISHED STANDARDS In addition to NFPA standards, the following information pertaining to the installation and use of standby electric systems is available: NOTE: It is essential to use the latest version of any standard to ensure correct and current information. • Article X, NATIONAL BUILDING CODE, available from the American Insurance Association, 85 John Street, New York, N.Y. 10038. • AGRICULTURAL WIRING HANDBOOK, obtainable from the Food and Energy Council, 909 University Avenue, Columbia, MO, 65201. • ASAE EP-364.2, INSTALLATION AND MAINTENANCE OF FARM STANDBY ELECTRIC POWER, available from the American Society of Agricultural Engineers, 2950 Niles Road, St. Joseph, MI 49085. • A52.1, AMERICAN NATIONAL STANDARD FOR CHIMNEYS, FIREPLACES AND VENTING SYSTEMS, available from the American National Standard Institute, 1430 Broadway, New York, N.Y. 10018. 2.2 • Where strong prevailing winds blow from one direction, face the generator air inlet openings into the prevailing winds. • Install the generator as close as possible to the transfer switch. This reduces the length of wiring and conduit. • Install the generator as close as possible to the fuel supply, to reduce the length of piping. HOWEVER, REMEMBER THAT LAWS OR CODES MAY REGULATE THE DISTANCE. 2.3 GENERATOR MOUNTING AND SUPPORT Retain the generator compartment to a concrete slab with 1/4-inch masonry type anchor bolts. Be sure the bolts are long enough to retain the compartment. The slab should be at least six inches thick and should extend beyond the enclosure to a distance of at least three inches on all sides. See Section 6, Installation Diagram. 2.4 BASIC STANDBY ELECTRIC SYSTEM Figure 2.1 shows a schematic diagram of a basic standby electric system. Both the UTILITY power supply and the STANDBY (generator) output are connected to an approved transfer switch. The transfer switch is required by electrical code and serves the following functions: • Permits the LOAD circuits to be connected to only one power supply at a time. • Prevents electrical backfeed between the generator and the UTILITY power circuits. Notice that both the STANDBY and the UTILITY power supplies to the transfer switch are protected against overload by a main line circuit breaker. Figure 2.1 – Basic Standby Electric System GENERATOR LOCATION Install the generator set, in its protective enclosure outdoors, where adequate cooling and ventilating air always is available. Consider these factors: • Install the unit where air inlet and outlet openings will not become obstructed by leaves, grass, snow, etc. If prevailing winds will cause blowing or drifting, consider using a windbreak to protect the unit. • Install the generator on high ground where water levels will not rise and endanger it. • Allow sufficient room on all sides of the generator for maintenance and servicing. Five feet allowance of space is recommended on all sides. Local codes may supercede this recommendation. Bryant recommends the use of a Bryant transfer switch in conjunction with this generator. Bryant 9 Section 2 — Installation Bryant Liquid-cooled 15 kW Generators 2.5 EMERGENCY CIRCUIT ISOLATION METHOD This prevents overloading the generator by keeping electrical loads below the wattage/amperage capacity of the generator. If the generator is powering only critical loads, within the wattage/amperage capacity, during utility power outages, consider using the emergency circuit isolation method. Proper grounding helps protect personnel against electrical shock in the event of a ground fault condition in the generator or in connected electrical devices. In addition, grounding helps dissipate static electricity that often builds up in ungrounded devices. Figure 2.2 – Generator Grounding Lug (typical) Critical electrical loads are grouped together and wired into a separate “Emergency Distribution Panel.” Load circuits powered by that panel are within the wattage/amperage capacity of the generator set. When this method is used, it is difficult to overload the generator. The transfer switch must meet the following requirements: • It must have an ampere rating equal to, or greater than, the total amperage rating of the emergency distribution panel circuit. • Have it installed between the building’s main distribution panel and the emergency distribution panel. 2.6 TOTAL CIRCUIT ISOLATION METHOD When a generator capable of powering all electrical loads in the circuit is to be installed, use the “Total Circuit Isolation Method.” It is possible for the generator to be overloaded when this isolation method is employed. The following apply to the transfer switch in this type of system. • Ampere rating of the transfer switch must be equal to, or greater than, the ampere rating of the normal incoming utility service. • The transfer switch is installed between the utility service entrance and the building distribution panel. 2.7 GROUNDING THE GENERATOR The National Electrical Code requires the frame and external electrically conductive parts of this equipment to be properly connected to an approved earth ground and/or grounding rods. For that purpose, a GROUND LUG (Figure 2.2) is provided on the generator mounting base. Consult a qualified electrician for grounding requirements in the area. Grounding procedures must meet local regulations. DANGER Do not connect the ground wire to any pipe that carries a flammable or explosive substance – FIRE or an EXPLOSION may result. 10 Bryant 2.8 GENERATOR AC NEUTRAL CONNECTIONS Bryant uses an UNGROUNDED AC neutral. Grounding is recommended only at the main service entrance. If the neutral wire is grounded and one of the phase loads becomes grounded, the excessive current opens the load circuit breaker or collapses the generator field. The actual result depends on the electrical characteristics of the particular installed generator. ! 2.9 Failure to connect the generator neutral properly will result in unbalanced line-to-neutral voltages. Resulting high voltages will cause equipment damage. TRANSFER SWITCH SIGNAL CONNECTIONS It is necessary to connect the control wires between the generator and the transfer switch. Control system interconnections consist of N1, N2, T1, T2 and leads 23 and 194. Control system interconnection leads must be run in a conduit that is separate from the AC power lead. Recommended wire gauge sizes for this wiring depends on the length of the wire, as recommended below: MAXIMUM WIRE LENGTH 460 feet (140m) 461 to 730 feet (223m) 731 to 1,160 feet (354m) 1,161 to 1,185 feet (565m) RECOMMENDED WIRE SIZE No. 18 AWG. No. 16 AWG. No. 14 AWG. No. 12 AWG. Section 2 — Installation Bryant Liquid-cooled 15 kW Generators 2.10 BATTERY INSTALLATION DANGER ! Standby generators installed with automatic transfer switches 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, do not connect battery cables until the NORMAL source voltage at the transfer switch is correct and the system is ready to be put into operation. Storage batteries give off explosive hydrogen gas. This gas can form an explosive mixture around the battery for several hours after charging. The slightest spark can ignite the gas and cause an explosion. Such an explosion can shatter the battery and cause blindness or other injury. Any area that houses a storage battery must be properly ventilated. Do not allow smoking, open flame, sparks or any spark producing tools or equipment near the battery. ! ! Battery electrolyte fluid is an extremely caustic sulfuric acid solution that can cause severe burns. Do not permit fluid to contact eyes, skin, clothing, painted surfaces, etc. Wear protective goggles, protective clothing and gloves when handling a battery. If the fluid is spilled, flush the affected area immediately with clear water. Do not dispose of the battery in a fire. The battery is capable of exploding. Do not open or mutilate the battery. Released electrolyte can be toxic and harmful to the skin and eyes. The battery represents a risk of high short circuit current. When working on the battery, always remove watches, rings or other metal objects, and only use tools that have insulated handles. 2.10.1 VENTED BATTERIES The electrolyte is a dilute sulfuric acid that is harmful to the skin and eyes. It is electrically conductive and corrosive. The following procedures are to be observed: • Wear full eye protection and protective clothing, • Where electrolyte contacts the skin, wash it off immediately with water, • Where electrolyte contacts the eyes, flush thoroughly and immediately with water and seek medical attention, and ! • Spilled electrolyte is to be washed down with an acid-neutralizing agent. A common practice is to use a solution of one pound (500 grams) bicarbonate of soda to one gallon (4 liters) of water. The bicarbonate of soda solution is to be added until the evidence of reaction (foaming) has ceased. The resulting liquid is to be flushed with water and the area dried. Lead acid batteries present a risk of fire because they generate hydrogen gas. The following procedure are to be followed: • DO NOT SMOKE when near batteries, • DO NOT cause flame or spark in battery area, and • Discharge static electricity from body before touching batteries by first touching a grounded metal surface. Servicing of batteries is to be performed or supervised by personnel knowledgeable of batteries and the required precautions. Keep unauthorized personnel away from batteries. The recommended battery is Group 26, 12V negative ground, 525 CCA/75 AH minimum. All batteries must be at 100 percent state-of-charge before they are installed on the generator. When using maintenance-free batteries, it is not necessary to check the specific gravity or electrolyte level. Have these procedures performed at the intervals specified in Section 4, “Maintenance.” A negative ground system is used. Battery connections are shown on the wiring diagrams. Make sure all batteries are correctly connected and terminals are tight. Observe battery polarity when connecting batteries to the generator set. NOTE: Damage will result if the battery connections are made in reverse. 2.11 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. Be sure to read the “Safety Rules” on pages 2 and 3, as well as all other safety information in this manual, before attempting to operate this (and related) equipment. 2.11.1 PRIOR TO INITIAL START-UP ! Prior to initially starting the generator, it must be properly prepared for use. Any attempt to crank or start the engine before it has been properly serviced with the recommended types and quantities of engine fluids (oil, coolant, fuel, etc.) may result in an engine failure. Bryant 11 Section 3 — Operation Bryant Liquid-cooled 15 kW Generators Before starting the generator for the first time, the installer must complete the following procedures. For follow-up maintenance information and/or service intervals, please refer to Section 4, “Maintenance.” 2.11.2 TRANSFER SWITCH If this generator is used to supply power to any electrical system normally powered by an electric utility, the National Electrical Code requires that a transfer switch be installed. The transfer switch prevents electrical backfeed between two different electrical systems. (For additional information, see the applicable transfer switch manual for this unit.) The transfer switch, as well as the generator and other standby components, must be properly located and mounted in strict compliance with applicable codes, standards and regulations. 2.11.7 ELECTRICAL SYSTEM Make sure the generator is properly connected to an approved earth ground and/or ground rod. Make sure the generator battery is fully charged, properly installed and interconnected, and ready for use. Check to ensure that there are no loose electrical connections. Restrain any loose wires to keep them clear of any moving generator set components. 3.1 CONTROL CONSOLE COMPONENTS The components of a liquid-cooled generator control console (Figure 3.1) are as follows: Figure 3.1 - Liquid-Cooled Generator Panel 2.11.3 FUEL SYSTEM Make sure the fuel supply system to the generator (a) delivers the correct fuel at the correct pressure and (b) is properly purged and leak tested according to code. No fuel leakage is permitted. See “Specifications” (Section 1.10) for more information. HOUR METER FUSE 15-A AGC FAULT INDICATOR 2.11.4 GENERATOR SET LUBRICATION Check the engine crankcase oil level before operating and add oil to the proper level – the dipstick “FULL” mark. Never operate the engine with the oil level below the dipstick “ADD” mark. See “Specifications” (Section 1.10) and “Engine Oil Recommendations” (Section 1.14). AUTO ON MANUAL NOTE: This engine is shipped from the manufacturer with 15W-40 oil. This oil should be changed after 30 hours of operation. 2.11.5 ENGINE COOLANT Have the engine cooling system properly filled with the recommended coolant mixture. Check the system for leaks and other problems. See “Specifications” (Section 1.10) and “Coolant” (Section 1.15). 3.1.1 12 Bryant AUTO/OFF/MANUAL SWITCH Use this three-position switch as follows: • Set the switch to AUTO for fully automatic operation. See “Automatic Operation”, Section 3.4. • Set switch to MANUAL position to crank and start the generator engine. • Set switch to OFF position to shut down an operating engine. With OFF selected, operation will not be possible. DANGER 2.11.6 BELT TENSION Check the engine fan belt tension and condition prior to placing the unit into service and at recommended intervals. Belt tension is correct when a force of approximately 22 pounds (10 kg), applied midway between pulleys, deflects the belt about 3/8- to 5/8inch (10 to 16 mm). SET EXERCISE TIME OFF ! With switch set to AUTO, engine can crank and start suddenly without warning. Such automatic start up normally occurs when UTILITY source voltage drops below a pre-set level. To prevent possible injury that might be caused by such sudden starts, set AUTO/OFF/MANUAL switch to OFF before working on or around the unit. Then, place a "DO NOT OPERATE" tag on control console. Section 3 - Operation Bryant Liquid-cooled 15 kW Generators 3.1.2 FAULT INDICATOR LAMP The lamp goes ON when one or more of the following engine faults occurs and when engine shuts down. • Low oil pressure • High coolant temperature • Low coolant level 3.1.3 • Overcrank • Overspeed 15 AMP FUSE The fuse protects the control console’s DC control circuit against electrical overload. If the fuse has melted open because of an overload, engine cranking and startup cannot occur. If replacement of the fuse is necessary, use only an identical 15-amp fuse. (Type AGC, part number 022676). 3.1.4 7.5 AMP INLINE FUSE This inline fuse is connected in the 15A line that runs between the AUTO/OFF/MANUAL switch and position 10 of the 76009A PCB. This fuse protects the start, fuel, field boost, and transfer outputs from the PCB and will open if there is excessive current draw on any one of these outputs. NOTE: This fuse will not remove the positive (+) battery input power from the PCB when it opens. This means the exercise timer will not be reset. If this fuse does open, carefully check the wiring to the start, fuel, field boost and transfer outputs before replacing the fuse. 3.1.5 SET EXERCISE TIME SWITCH This switch allows for programming the generator to start and exercise automatically. See “Weekly Exercise Cycle” (Section 3.5). 3.2 MANUAL TRANSFER AND START-UP 3.4 To select day and time for exercising, proceed as follows: • Set the AUTO/OFF/MANUAL switch to OFF. • Set generator main circuit breaker to OFF or OPEN. • Locate the rocker switch on the control panel identified with the words “Set Exercise Time” (Figure 3.2). • Push “Set Exercise Time” switch to ON position for 20 to 30 seconds and then release. Switch will spring back into its original position when released. • Wait 30 seconds before setting the AUTO/OFF/ MANUAL switch to AUTO position. If the AUTO/OFF/MANUAL switch is switched too soon, the engine may start. If engine does start, it will shut down automatically in about two (2) minutes. • Set the generator main circuit breaker to its ON or CLOSED position. • Generator is now programmed to start and exercise every seven days thereafter, on day and time of day the switch was actuated. • Place a sign on the generator control panel and the transfer switch, indicating the day and time the generator will be exercising. NOTE: ! If battery terminals are disconnected, the exercise timer needs to be reset for correct automatic exercise operation. To transfer electrical loads to the STANDBY (GENERATOR) power source side and start the engine manually, refer to the Owner’s Manual of the particular transfer switch. 3.3 AUTOMATIC OPERATION To set the system for fully automatic operation, proceed as follows: • Check that load circuits are connected to the utility power supply. • Set the AUTO/OFF/MANUAL switch to its AUTO position. • Set the generator main circuit breaker to its ON or CLOSED position. WEEKLY EXERCISE CYCLE The generator will start and exercise once every seven days. During this weekly exercise, the unit runs for about 20 minutes and shuts down. Transfer of loads to generator output does not occur during the exercise.

(See Torque Specs, Section 1.13.) 3.Check engine compression. 4.Check valve clearance. 4.2 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. Without sufficient cooling and ventilating air flow, the engine/generator quickly overheats, which causes it to shut down. (See Section 7 for installation drawings and vent locations.) 14 Bryant OVERLOAD PROTECTION FOR ENGINE DC ELECTRICAL SYSTEM 4.4 If a circuit breaker opens or a fuse element melts, find the cause of the overload before resetting the circuit breaker or replacing the fuse. CHECKING FLUID LEVELS 4.4.1 CHECK ENGINE OIL Check engine crankcase oil level (Figure 4.1) at least every 20 hours of operation, or prior to use. • Remove oil dipstick and wipe dry with a clean, lint-free cloth. • Install oil dipstick, then remove again. • Oil should be between FULL and ADD marks. • If oil level is below the dipstick ADD mark, remove oil fill cap. Add the recommended oil to bring oil level up to the FULL mark. DO NOT FILL ABOVE THE “FULL” MARK. See Section 1.14 for recommended oils. Figure 4.1 - Oil Dipstick and Oil Fill Cap OIL DIPSTICK Section 4 — Maintenance Bryant Liquid-cooled 15 kW Generators 4.4.2 BATTERY FLUID 4.5.7 INSPECT EXHAUST SYSTEM Check battery electrolyte fluid at least once a month. Fluid should cover separators in all battery cells. If fluid level is low, add distilled water to cover tops of separators. DO NOT USE TAP WATER IN BATTERY. Inspect the exhaust system at least once every three months. Check all exhaust system pipes, mufflers, clamps, etc. for condition, tightness, leaks, security, damage. 4.4.3 4.5.8 ENGINE COOLANT Check coolant level in coolant recovery bottle. See Specifications, Section 1.10. • Add recommended coolant mixture as necessary. • Periodically remove radiator pressure cap to make sure the coolant recovery system is functioning properly. Coolant should be at bottom of radiator filler neck. If coolant level is low, inspect gasket in radiator pressure cap. Replace cap, if necessary. To have pressure cap tested, contact a dealer. Inspect cooling system and coolant recovery system for leaks. 4.5 MAINTENANCE OWNER/ OPERATOR CAN PERFORM 4.5.1 CHECK ENGINE OIL LEVEL Refer to “Checking Fluid Levels” in Section 4.4. 4.5.2 CHECK BATTERY • Check battery fluid level each week as outlined under “Check Fluid Levels”. • Check battery cables for condition, tightness, corrosion or damage. Clean, tighten or replace as necessary. 4.5.3 EXERCISE SYSTEM Start the generator engine at least once every seven days and let it run at least 20 minutes. See Section 3.5, “Weekly Exercise Cycle”. 4.5.4 INSPECT COOLING SYSTEM • Inspect engine cooling system at least once each month. • Check hoses for damage, deterioration, leaks, etc. Correct any discrepancies found. • Check hose clamps for tightness. 4.5.5 CHECK ENGINE COOLANT LEVEL See “Checking Fluid Levels” in Section 4.4. 4.5.6 PERFORM VISUAL INSPECTION Complete a thorough visual inspection of the entire engine-generator monthly. Look for obvious damage, loose, missing or corroded nuts, bolts and other fasteners. Look for fuel, oil or coolant leaks. CHECK FAN BELT • 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 3/4 inch. Adjust belt tension as required. 4.5.9 INSPECT ENGINE GOVERNOR Visually inspect electronic governor. DANGER ! Do not attempt to adjust the governor. Only qualified service facilities should adjust the governor. Excessively high operating speeds are dangerous and increase the risk of personal injury. Low speeds impose a heavy load on the engine when adequate engine power is not available and may shorten engine life. Correct rated frequency and voltage are supplied only at the proper governed speed. Some connected electrical load devices may be damaged by incorrect frequency and/or voltage. Only qualified service technicians should adjust the governed speed. 4.5.10 CHANGING ENGINE OIL Refer to maintenance performed by authorized service facilities for engine oil and filter change frequencies. 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. When all oil has drained, install and tighten OIL DRAIN HOSE CAP, and re-install into its retaining clip. 4. Turn OIL FILTER (Figure 4.2) counterclockwise and remove. Dispose of old filter. 5. Apply light coating of new engine oil to seal of new oil filter. Install FILTER and tighten by hand only. DO NOT OVERTIGHTEN. 6. Remove OIL FILL CAP. Add recommended oil (see SPECIFICATIONS). DO NOT FILL ABOVE THE DIPSTICK “FULL” MARK. Crankcase oil capacity is 4.0 U.S. quarts (3.8 liters). Bryant 15 Section 4 — Maintenance Bryant Liquid-cooled 15 kW Generators Figure 4.2 - Oil Filter 4.5.12 SPARK PLUGS Reset the spark plug gap or replace the spark plugs as necessary. See Section 4.7. OIL FILTER 1. Clean the area around the base of the spark plugs to keep dirt and debris out of the engine. Clean by scraping or washing using a wire brush and commercial solvent. Do not blast the spark plugs to clean. 2. Remove the spark plugs and check the condition. Replace the spark plugs if worn or if reuse is questionable. See the “Scheduled Maintenance,” Section 4.7, for recommended inspection. 3. Check the spark plug gap using a wire feeler gauge. Adjust the gap to 0.5-0.6 mm (0.020-0.025 inch) by carefully bending the ground electrode (Figure 4.4). Figure 4.4 – Setting the Spark Plug Gap After refilling the crankcase with oil, always check oil level on dipstick. NEVER OPERATE ENGINE WITH OIL BELOW THE DIPSTICK “ADD” MARK. 7. Start engine and check for oil leaks. ! SET PLUG GAP AT 0.5-0.6 mm (0.020-0.025 inch) 4.5.11 CHANGING THE ENGINE AIR CLEANER To replace the engine air cleaner, (part number 059402), simply remove the air cleaner cover and replace the air filter making sure it is positioned properly before reattaching the cover (Figure 4.3). Figure 4.3 – Engine Air Cleaner Air Cleaner 4.5.13 COOLANT CHANGE Every year, have a dealer drain, flush and refill the cooling system. See SPECIFICATIONS (Section 1.10) for cooling system recommendations. 4.6 MISCELLANEOUS MAINTENANCE 4.6.1 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. (Doors Removed for Clarity) See the “Scheduled Maintenance,” Section 4.7, for air cleaner maintenance. Periodically clean generator exterior surfaces. A soft brush may be used to loosen caked on dirt. Use a vacuum system or dry, low pressure air to remove any accumulations of dirt. The generator is housed inside an all-weather enclosure, clean the enclosure with a soft, damp cloth or sponge and water. Apply a coat of automotive type wax once a year to help prevent corrosion. Once each year, have the generator cleaned and inspected by a dealer. That dealer will use dry, low pressure air to clean internal windings. Parts inside the control console should be cleaned and inspected at this time as well. 16 Bryant Section 4 — Maintenance Bryant Liquid-cooled 15 kW Generators Finally, have the insulation resistance of stator and rotor windings checked. If insulation resistances are excessively low, the generator may require drying. 4.6.2 DANGER Storage batteries give off explosive hydrogen gas. This gas can form an explosive mixture around the battery for several hours after charging. The slightest spark can ignite the gas and cause an explosion. Such an explosion can shatter the battery and cause blindness or other injury. Any area that houses a storage battery must be properly ventilated. Do not allow smoking, open flame, sparks or any spark producing tools or equipment near the battery. BATTERY 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: • DO NOT use jumper cables and a booster battery to crank or start the generator engine. • DO NOT recharge a weak battery while it is installed in the generator. Remove battery from generator and recharge in a well-ventilated area, away from fuel vapors, sparks, heat or flames. • Battery electrolyte fluid is an extremely caustic sulfuric solution that can cause severe burns. DO NOT permit fluid to contact eyes, skin, clothing, painted surfaces, wiring insulation, etc. If any battery fluid is spilled, flush the affected area with clear water immediately. • Always wear safety glasses, rubber apron and gloves when handling a battery. • Batteries give off explosive hydrogen gas while charging. The gas can form an explosive mixture around the battery for several hours after charging. Any spark, heat or flames can ignite the gas and cause an explosion which can shatter the battery, causing blindness or other serious injury. 4.6.3 BATTERY MAINTENANCE The battery should be inspected per the “Scheduled Maintenance,” Section 4.7. The following procedure should be followed for inspection: 1. Inspect the battery posts and cables for tightness and corrosion. Tighten and clean as necessary. 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. ! Battery electrolyte fluid is an extremely caustic sulfuric acid solution that can cause severe burns. Do not permit fluid to contact eyes, skin, clothing, painted surfaces, etc. Wear protective goggles, protective clothing and gloves when handling a battery. If the fluid is spilled, flush the affected area immediately with clear water. ! Do not use any jumper cables or booster battery to crank and start the generator engine. If the battery has completely discharged, remove it from the generator for recharging. ! Be sure the AUTO/OFF/MANUAL switch is set to 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. Be sure the UTILITY power supply is turned off, or sparking may occur at the battery posts as the cables are attached and cause an explosion. 4.6.4 BATTERY REPLACEMENT When replacing batteries, use the same number and the type of battery that follows: BCI Group No. 26 CCA 525 @ 0 deg.

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. Use the unit hour meter or calendar time, whichever occurs first, from the previous maintenance interval to determine the next required maintenance interval. Service Maintenance Interval Information: The various service maintenance intervals are designated by interval numbers as follows: 1 An early inspection of the generator set to insure it is ready to operate when required and to identify any potential problem areas. Performed monthly or following each 10 hours of operation of the unit and requires approximately .5 manhours per unit to complete. This inspection may be performed by the end user providing the following safety steps are taken to prevent the engine from starting automatically without warning: To prevent injury, perform the following steps in the order indicated before starting any maintenance: • Disable the generator set from starting and/or connecting to the load by setting the control panel AUTO-OFF-MANUAL switch to the OFF position. • Remove the control panel fuse. • Turn off utility supply to engine water heater. • Turn off the battery charger by turning off utility supply to the transfer switch. • Remove the negative battery cable. The battery charger must be turned off BEFORE removing the battery cable to prevent an over current condition from burning out sensitive control panel components and circuits. Following all maintenance, reverse these steps to insure the unit is returned to standby setup for normal operation when required. 2 A break-in service inspection of the generator set to insure it is ready to operate and carry the load when required, and to identify any potential problem areas. Performed ONLY ONCE following the first three months or the first 30 hours of operation after purchase of the unit and requires approximately 2.5 man-hours per unit to complete. This inspection contains some maintenance tasks which require special tools, equipment, and/or knowledge to accomplish and should be performed only by a dealer. 3 An operational inspection of the generator set to insure it is ready to operate and carry the load when required, and to identify any potential problem areas. Performed semi-annually or following each 50 hours of operation of the unit and requires approximately 1.5 man-hours per unit to complete. This inspection contains some maintenance tasks which require special tools, equipment, and/or knowledge to accomplish and should be performed only by a dealer. 4 A mid-level inspection of the generator set to insure it is ready to operate and carry the load when required, and to identify any potential problem areas.

(Generac) are pleased to explain the Emission Control System Warranty on your new engine.* In California, new utility, and lawn and garden equipment engines must be designed, built and equipped to meet the state’s stringent anti-smog standards. Generac will warrant the emission control system on your engine for the periods of time listed below provided there has been no abuse, neglect, unapproved modification or improper maintenance of your engine. Your emission control system may include parts such as the carburetor, ignition system and exhaust system. Generac will repair your engine at no cost to you for diagnosis, replacement parts and labor, should a warrantable condition occur. MANUFACTURER’S EMISSION CONTROL SYSTEM WARRANTY COVERAGE: Emissions control systems on 1995 and later model year engines are warranted for two years as hereinafter noted. If, during such warranty period, any emission-related component or system on your engine is found to be defective in materials or workmanship, repairs or replacement will be performed by a Generac Authorized Warranty Service Facility. PURCHASER’S/OWNER’S WARRANTY RESPONSIBILITIES: As the engine purchaser/owner, you are responsible for the completion of all required maintenance as listed in your factory supplied Owner’s Manual. For warranty purposes, Generac recommends that you retain all receipts covering maintenance on your engine. However, Generac cannot deny warranty solely due to the lack of receipts or for your failure to ensure the completion of all scheduled maintenance. As the engine purchaser/owner, you should, however, be aware that Generac may deny any and/or all warranty coverage or responsibility if your engine, or a part/component thereof, has failed due to abuse, neglect , improper maintenance or unapproved modifications, or the use of counterfeit and/or “grey market” parts not made, supplied or approved by Generac. Warranty service can be arranged by contacting Generac Power Systems, Inc.. IMPORTANT NOTE: This warranty statement explains your rights and obligations under the Emission Control System Warranty (ECS Warranty), which is provided to you by Generac pursuant to California law. See also the “Bryant Two Year Limited Warranty for Prepackaged Emergency Automatic Standby Generators” which is enclosed herewith on a separate sheet, also provided to you by Generac. The ECS Warranty applies only to the emission control system of your new engine. If there is any conflict in terms between the ECS Warranty and the Bryant Warranty, the ECS Warranty shall apply except in circumstances where the Generac Warranty may provide a longer warranty period. Both the ECS Warranty and the Bryant Warranty describe important rights and obligations with respect to your new engine. Warranty service can be performed only by a Generac Authorized Warranty Service Facility. When requesting warranty service, evidence must be presented showing the date of the sale to the original purchaser/owner. To arrange for emissions equipment warranty or if you have any questions regarding your warranty rights and responsibilities, you should contact Generac at the following address: ATTENTION WARRANTY DEPARTMENT GENERAC POWER SYSTEMS, INC. P.O. BOX 297 WHITEWATER, WI 53190 www.generac.com Part 1 44 Bryant Section 10 – Warranty Bryant Liquid-cooled 15 kW Generators EMISSION CONTROL SYSTEM WARRANTY Emission Control System Warranty (ECS Warranty) for 1995 and later model year engines: (a) Applicability: This warranty shall apply to 1995 and later model year engines. The ECS Warranty Period shall begin on the date the new engine or equipment is purchased by/delivered to its original, end-use purchaser/owner and shall continue for 24 consecutive months thereafter. (b) General Emissions Warranty Coverage: Generac warrants to the original, end-use purchaser/owner of the new engine or equipment and to each subsequent purchaser/owner that each of its engines is ... (1) Designed, built and equipped so as to conform with all applicable regulations adopted by the CARB pursuant to its authority, and (2) Free from defects in materials and workmanship which, at any time during the ECS Warranty Period, may cause a warranted emissions-related part to fail to be identical in all material respects to the part as described in the engine manufacturer’s application for certification. (c) The ECS Warranty only pertains to emissions-related parts on your engine, as follows: (1) Any warranted, emissions-related parts that are not scheduled for replacement as required maintenance in the Owner’s Manual shall be warranted for the ECS Warranty Period. If any such part fails during the ECS Warranty Period, it shall be repaired or replaced by Generac according to Subsection (4) below. Any such part repaired or replaced under the ECS Warranty shall be warranted for the remainder of the ECS Warranty Period. (2) Any warranted, emissions-related part that is scheduled only for regular inspection as specified in the Owner’s Manual shall be warranted for the ECS Warranty Period. A statement in such written instructions to the effect of “repair or replace as necessary” shall not reduce the ECS Warranty Period. Any such part repaired or replaced under the ECS Warranty shall be warranted for the remainder of the ECS Warranty Period. (3) Any warranted, emissions-related part that is scheduled for replacement as required maintenance in the Owner’s Manual shall be warranted for the period of time prior to the first scheduled replacement point for that part.
