IMPORTANT SAFETY INSTRUCTIONS Bryant Liquid-cooled 15 kW Generators ! SAVE THESE INSTRUCTIONS – The manufacturer suggests that these rules for safe operation be copied and posted in potential hazard areas. Safety should be stressed to all operators, potential operators, and service and repair technicians for this equipment. ! SAVE THESE INSTRUCTIONS – This manual contains important instructions that should be followed during installation and maintenance of the generator and batteries.
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.
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.
Section 1 - General Information Bryant Liquid-cooled 15 kW Generators 1.6 GENERATOR FUEL SYSTEM The generator has been factory tested and adjusted using a natural gas fuel system. 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.
Section 1 — General Information Bryant Liquid-cooled 15 kW Generators • LED 3 is GREEN. This LED will flash when the circuit board has load voltage available to it. This LED will function when voltage is available across T1 and T2. Figure 1.6 - Low Coolant Level Sensor 1.7.6 OVERCRANK SHUTDOWN After 90 seconds of crank-rest cycles, this function ends cranking if the engine fails to start in that 90-second span. 1.7.6 1.7.

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.
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.
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.
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.
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.
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.
Section 4 — Maintenance Bryant Liquid-cooled 15 kW Generators 4.1 MAINTENANCE PERFORMED BY AUTHORIZED SERVICE FACILITIES The exhaust system parts from this product get extremely hot and remains 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. A. EVERY THREE MONTHS 1.Check battery state of charge and condition. 2.Inspect and test fuel system. 3.Check transfer switch. 4.
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.
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.
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.
Section 4 — Maintenance Bryant Liquid-cooled 15 kW Generators 4.7 SCHEDULED MAINTENANCE 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.
