Never work on the equipment when you are physically or mentally fatigued. WARNING! • An adequate, unobstructed flow of cooling and ventilating air is critical for 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.The Oil Service door and/or the Control Panel door must be installed whenever the unit is running. Only qualified electricians and gaseous fuel technicians should attempt installation of this system, which must strictly comply with applicable codes, standards and regulations. • Your Briggs & Stratton Backup Power System produces dangerous electrical voltages that can cause a fatal electrical shock. Avoid contact with bare wires, terminals and connections at all times while the unit is running. Ensure that all the appropriate covers, guards and barriers are in place before operating the generator. If you must work around a unit while it is operating, stand on an insulated dry surface to reduce shock hazard. • Before performing any maintenance on the generator, remove the 15 Amp fuse AND disconnect the battery NEGATIVE, NEG, or (-) cable. • Do Not operate engine if smell of fuel is present or other explosive conditions exist. • Do Not tamper with governor springs, links or other parts to increase engine speed. • In case of an accident caused by electrical shock immediately shut down the source of electrical power. If this is not possible, attempt to free the victim from the live conductor. • Do Not touch hot muffler, engine cylinder, or engine exhaust port which can cause burns. • Do Not start engine with air cleaner or air cleaner cover removed. DANGER! Avoid direct contact with the victim. Use a non-conducting implement, such as a rope or board to free the victim from the live conductor. If the victim is unconscious, apply first aid and get immediate medical help. CAUTION! Despite the safe design of the Backup Power System, operating this equipment imprudently, neglecting its maintenance or being careless can cause possible injury or death. Permit only responsible and capable persons to operate and/or maintain this equipment. • Your Backup Power System is powered by gaseous fuel. Liquid Propane (LP) or natural gas is extremely Explosive! Do Not smoke around the generator.Wipe up any oil spills immediately. Ensure that no combustible materials are left in the generator compartment. Keep the area near the generator clean and free of debris. NOTE: Your generator is equipped with a spark arrester muffler.The spark arrester must be maintained in effective working order by the owner/operator. In the State of California, a spark arrester is required by law (Section 4442 of the California Public Resources Code). Other states may have similar laws. Federal laws apply on federal lands. • Do Not use the generator or any of its parts as a step. Stepping on the unit can stress and break parts.This may result in dangerous operating conditions from leaking exhaust gases, fuel leakage, oil leakage, etc. The manufacturer cannot possibly anticipate every possible circumstance that might involve a hazard.The warnings in this manual, and the tags and decals affixed to the unit are, therefore, not all-inclusive. If you use a procedure, work method or operating technique that the manufacturer does not specifically recommend, you must satisfy yourself that it is safe for you and others.You must also make sure that the procedure, work method or operating technique that you choose does not render the generator unsafe. CAUTION! After the installation of your Backup Power System is complete, the generator may crank and start without warning any time there is a power interruption.To prevent possible injury, before working on the equipment, always set the AUTO/OFF/MANUAL switch to OFF and remove the 15 Amp fuse. • Do Not handle any kind of electrical device while standing in water. Avoid electrical devices while barefoot or while hands or feet are wet. 3 Briggs & Stratton Power Products Backup Power System Owner’s Manual INTRODUCTION To arrange for proper installation, contact the store at which you purchased your Briggs & Stratton Backup Power System, your dealer, or your utility power provider. Congratulations on your purchase of a Briggs & Stratton Backup Power System (BPS).Your BPS was designed to provide automatic auxiliary electrical power for the duration of normal power interruption. It is not intended for use as primary power in place of utility nor for use in life-support applications.The generator unit has been engineered and tested to exacting standards of performance and reliability and is equipped with a UL® listed Automatic Power Transfer Switch. The BPS Warranty is VOID unless the system is installed by certified electrical and plumbing professionals. For the Installing Dealer/Contractor: For most applications, the Installation manual contains all the information required to properly install and start the Backup Power System.This Owner’s Manual describes essential circuit selection, routine operation and owner maintenance procedures. Generac Portable Products has made every effort to provide for a safe, streamlined and cost-effective installation. Because each installation is unique, it is impossible to know of and advise the trade of all conceivable procedures and methods by which installation might be achieved. Neither could we know of possible hazards and/or the results of each method or procedure. For these reasons, If you need more information, call 920-674-3750, extension 2716, between 8:00 AM and 5:00 PM CT. The Emission Control System for this generator is warranted for standards set by the U.S. Environmental Protection Agency and by the California Air Resources Board (CARB). For warranty information refer to the back of this Owner’s manual. Only current qualified electrical and plumbing contractors should attempt BPS installations. Installations must strictly comply with all applicable codes, industry standards and regulations. OWNER ORIENTATION This section provides Backup Power System owners with the information necessary to achieve the most satisfactory and cost effective installation possible. Your Briggs & Stratton Backup Power System is supplied with this “Owners Manual” and a separate “Installation Manual” (Generac part number 184957).These are both important documents and should be retained by the owner after the installation has been completed. The illustrations are for typical circumstances and are meant to familiarize you with the installation options available with your Backup Power System. A thorough understanding of these options will provide fundamental control over the cost of your installation, as well as ensure your final satisfaction and security. Installation Assistance Local codes, appearance, noise levels, fuel types, and distances are the factors that must be considered when negotiating with an installation professional. Remember that as the distance from the existing electrical service and gaseous fuel supply increases, equal compensations in piping and wiring materials must be allowed for.This is necessary to comply with local codes and overcome electrical voltage drops and gaseous fuel pressure drops. For the Home or Business Owner: To help you make informed choices and communicate effectively with your installation contractor(s), Read and understand the Owner Orientation Section of this manual BEFORE contracting or starting your BPS installation. The factors mentioned above will have a direct affect on the overall price of your Backup Power System installation. 4 Briggs & Stratton Power Products Backup Power System Owner’s Manual NOTE: In some areas you may need to acquire electrical permits for installing the Backup Power System, building permits for installing gas lines, and permits for noise allowances.Your installer should check your local codes AND obtain the permits before installing the system. Generator Location 1. The amount of plumbing required to fuel your generator. Fuel Factors 2. The amount of wiring required to control and connect your generator. The actual physical location of your backup generator has a direct affect on: An important consideration affecting the entire installation is the type of fuel used by your Backup Power System.The system was factory tested and adjusted using natural gas as a fuel. Liquid propane (LP) may also be used as a fuel (see the Installation Manual). NOTE: Specific location guidelines are discussed in the Installation Manual. Acquaint yourself with that information and confer with your installer. Be sure to ask how your site might affect installation costs and compliance with local codes and standards. Although there are specific factors that are inherent to each of these fuels, your location and the duration of possible utility interruptions should guide your selection of fuel type. For urban installations, Natural Gas (if available) should be your fuel of choice. For remote installations, a Liquefied Petroleum (LP) tank might better meet your needs. Generator Clearances The generator enclosure must be a minimum of 3 ft. (92 cm) from combustible material (NFPA 37). Leave at least 3 ft. (92 cm) all around the enclosure for access to the inside of the enclosure (NEC Art. 110-26a, Art. 110-26b). For proper engine function, the following fuel guidelines are recommended: The unit’s exhaust port must be at least 5 ft. (152 cm) from any building opening (window, door, vent etc.), and the exhaust must not be able to accumulate in any occupied area (Figure 1). • Use clean, dry fuel, free of moisture or any particulate material. Using fuels outside the following recommended values may cause performance problems. Figure 1 — Backup Power System Clearances In engines set up to run on propane (LP) gas, commercial grade HD5 propane with a minimum fuel energy of 2500 BTUs/ft3 with maximum propylene content of 5% and butane and heavier gas content of 2.5% and minimum propane content of 90%. CAUTION! This equipment is equipped with an automatic safety gas “fuel shut-off” valve. Do Not operate the equipment if the “fuel shut-off” valve is missing or inoperative. Exhaust Port Power Decrease at High Altitude or High Temperature Air density is less at high altitudes, resulting in less available engine power. Specifically, engine power will decrease 3.5% for each 1,000 feet (300 meters) above sea level and 1% for each 10° F (5.6°C) above 77°F (25°C). Make sure you and your installer consider these factors when determining total generator load. 5 Exhaust port must be 5 ft (152 cm) minimum distance from building openings Briggs & Stratton Power Products Backup Power System Owner’s Manual can be switched to the Backup Power System for the duration of normal power interruption. Figure 2 identifies system components and shows typical installation details.Variations to this illustration are related to code issues, piping distances and materials. The essential circuits are gathered in a special circuit breaker box, referred to as the Essential Circuit “subpanel”, that is connected by conduit to the transfer switch. This breaker box is provided by the installer because it allows him to use the brand that is most compatible with your existing electrical service components. Essential Circuits As a Backup Power System owner, it is important that you clearly identify the circuits in your building that are "essential" to you. Because the Backup Power System is equipped with an Automatic Transfer Switch, your selection of essential circuits will be transferred to the Backup Power System within 15 seconds (+/- 5 seconds). The wattage reference guide shown in Figure 3 will assist you with your decision-making process. It provides the wattage used by many ordinary household devices. Use it as a guide when selecting your essential circuits. Review this information with your installer and ask about any technical considerations that might affect the cost of your installation. It is important that your installer understand which circuits you want to include as "Essential Circuits". Depending on the power consumed by these circuits, most or all of them Figure 2 — Typical Installation Diagram for Backup Power System Utility Power Meter Backup Power System Generator Power Leads Signal Leads Automatic Power Transfer Switch NEUTRAL to White wire GND to chassis Rear of Control Panel Power Lead Connections Control Signal Connections 6 Main Distribution Panel Essential Circuit Sub-panel Briggs & Stratton Power Products Backup Power System Owner’s Manual Essential Circuit Selection When selecting the essential circuits that will be switched to “Backup Power,” it is important that the sum of the combined circuit loads does not exceed the wattage/amperage capacity of the generator.To help you with your selection of essential circuits, please consider the following: Figure 3 — Wattage Reference Guide Running Watts 1700 Air Conditioner (12,000 Btu)* 3800 Air Conditioner (24,000 Btu)* Air Conditioner (40,000 Btu)* 6000 Battery Charger (20 Amp) 500 800 to 1000 Circular Saw (6-1/2") 5750 Clothes Dryer (Electric)* 700 Clothes Dryer (Gas)* 1150 Clothes Washer* 1750 Coffee Maker 2000 Compressor (1 HP)* 1400 Compressor (1/2 HP)* 1800 Compressor (3/4 HP)* 700 Curling Iron 650 Dehumidifier* 400 Electric Blanket 1500 Electric Range (per element) 1250 Electric Skillet 700 Freezer* 875 Furnace Fan (3/5 HP)* 500 to 750 Garage Door Opener* 1200 Hair Dryer 250 to 1100 Hand Drill 1200 Iron 800 Jet Pump* 100 Light Bulb 700 to 1000 Microwave Oven 1100 Milk Cooler* 300 Oil Burner on Furnace 400 Oil Fired Space Heater (140,000 Btu) 150 Oil Fired Space Heater (30,000 Btu) 225 Oil Fired Space Heater (85,000 Btu) 50 to 200 Radio 700 Refrigerator 200 Slow Cooker 2000 Submersible Pump (1 HP)* 1500 Submersible Pump (1/2 HP)* 2800 Submersible Pump (1-1/2 HP)* 800 to 1050 Sump Pump* Table Saw (10")* 1750 to 2000 Television 200 to 500 1000 to 1650 Toaster *Allow three (3) times listed watts for starting device Device Add up the total wattage of all electrical devices to be connected at one time.This total should NOT be greater than the generator’s wattage capacity. The rated wattage of lights can be taken from light bulbs. The rated wattage of tools, appliances and motors can usually be found on a data plate or decal affixed to the device. If the appliance, tool or motor does not give wattage, multiply 120 Volts times the ampere rating to determine watts (Volts x Amps = Watts). Some electric motors (induction types) require about three times more watts of power for starting than for running.This surge lasts for only a few seconds. Be sure you allow for this high starting wattage when selecting electrical devices that will be energized by the backup power system: Figure the watts required to start the largest motor. Add that to the total running watts of all other connected loads. This Briggs & Stratton Backup Power System complies with the following “stationary standby power rating”: The standby power rating is applicable for supplying emergency power for the duration of normal power interruption. No sustained overload capability is available for this rating. This rating is applicable to installations served by a reliable normal utility source.This rating is only applicable to variable loads with an average load factor of 80% of the standby rating for a maximum of 500 hours of operation per year.The standby rating is only applicable for emergency and standby power where the generator set serves as the backup to the normal utility source. Use the “Wattage Reference Guide” provided and mark those circuits you consider “critical” or “essential”. Make sure you and your installer consider the system’s altitude above sea level and the ambient temperature range when determining total generator load. 7 Briggs & Stratton Power Products Backup Power System Owner’s Manual UNPACKING Shipment Contents The Backup Power System is supplied with: Refer to the Installation Manual for detailed unpacking instructions, if desired. • Backup Power generator • Pre-attached mounting pad Delivery Inspection • Automatic Power Transfer switch After removing the carton, carefully inspect the Backup Generator and Automatic Power Transfer Switch components for any damage that may have occurred during shipment. • One 18” flexible fuel hook-up pipe IMPORTANT: If loss or damage is noted at time of delivery, have the person(s) making delivery note all damage on the freight bill and affix his signature under the consignor's memo of loss or damage.

Engine Oil • Ensure that all shutoff valves are OPEN and that adequate pressure is available. This engine is shipped from the factory filled with the recommended oil. Before starting the engine, check oil level and ensure that engine is serviced as described on page 18 in “Checking Oil Level”. If you smell ‘raw’ gaseous fuel (natural or LP) near the unit, immediately turn off the gas supply to the generator. Contact your gas utility or the system installer for assistance in determining the source of the smell. CAUTION! Any attempt to crank or start the engine before it has been properly serviced with the recommended oil will result in an engine failure that is not covered under warranty. The AUTO/OFF/MANUAL Switch This three-position device is referred to herein as “AUTO/OFF/MANUAL”. It is found on the control panel, as shown earlier, and is used as follows: Oil Considerations Your Backup Power System is equipped with an engine that has been pre-run at the factory and does not require the traditional “break-in” procedure. • “AUTO” position is the normal operating position. If a utility power outage is sensed, the system will start the generator, let it reach stable operating speed, then connect generator power to the sub-panel. When utility power is restored, the system reconnects utility power to the sub-panel, lets the engine ‘cool down’, shuts off the generator, and waits for the next utility power outage. In order to provide a greater “backup” capability, the system is filled with synthetic oil (API SJ/CF 5W-30W).This allows for system operation in the widest range of temperature and climate conditions. NOTE: The use of synthetic oil DOES NOT alter the required oil change intervals described later in the Maintenance section of this manual. • “OFF” position turns off a running generator, takes the system out of Automatic mode and resets faults.The unit will not exercise, but the ‘Set Exercise’ setting is not lost. Battery Connection • “MANUAL” position starts the engine but does not disconnect utility power from the sub-panel. It is used for maintenance or diagnostic functions. The Backup Power System is supplied with a 12 Volt DC 18 Amp-Hour sealed rechargeable battery. It is installed in the unit and the battery cables are connected at the factory.The unit’s 15 Amp fuse has been removed for shipping (this prevents the unit from starting). CAUTION! With the switch set to AUTO, the engine may crank and start at any time without warning. Such automatic starting normally occurs when utility source voltage drops below a preset level or during the normal exercise cycle.To prevent possible injury that might be caused by such sudden starts, always set the AUTO/OFF/MANUAL switch to OFF and remove the 15 Amp fuse before working on or around the generator or transfer switch. CAUTION! Do Not install the 15 Amp fuse until all plumbing and wiring has been completed and inspected. Failure to install the fuse as described in the Installation Manual could cause the engine to start. NOTE: With the battery installed, utility power supplied to the Automatic Transfer Switch, and the unit in AUTO mode, the battery receives a trickle charge while the engine is not running.The trickle charger cannot be used to recharge a battery that is completely discharged. The other controls and devices installed on the control panel are described on page 10, “Know Your System Control Panel”. 12 Briggs & Stratton Power Products Backup Power System Owner’s Manual AUTOMATIC OPERATION 5.

Causes for this problem may be a failed battery or a failed trickle charger circuit. Fault Detection System The generator may have to run for long periods of time with no operator present. For that reason, the system is equipped with sensors that automatically shut down the generator in the event of potentially damaging conditions, such as low oil pressure, high oil temperature, over speed, and other conditions. To remedy the problem, remove the 15 Amp fuse and disconnect the battery from the generator.Take the battery to a local battery store for analysis. Replace battery only with a genuine Generac part number 188443. A light on the control panel called the Diagnostic LED will turn on and off in a series of blinks.The blink pattern is repeated with a brief pause between each series.The number of blinks in the series indicates the detected fault, as listed on the control panel and below: Number of LED Flashes 1 2 3 4 5 6 7 Replace the battery in the battery compartment after it has been fully recharged, connecting the NEGATIVE cable last. Install the 15 Amp fuse. Reset the Fault Detection system as described above. Check battery trickle charge output. Low Oil Pressure This fault is indicated by two blinks.The unit is equipped with an oil pressure switch (Figure 5) using normally closed contacts that are held open by engine oil pressure during operation. Should oil pressure drop below the 8 psi range, switch contacts close and the engine is shut down. Fault Description Low battery voltage Low oil pressure Low voltage Engine fail to start Low frequency Engine overspeed Oil temperature high Figure 5 — Low Oil Pressure & High Temp. Switches Reset Fault Detection System The operator must reset the fault detection system each time it activates.To do so, place the AUTO/OFF/MANUAL switch in the OFF position for 30 seconds or more. Return the backup power system to service after correcting the problem by placing the AUTO/OFF/MANUAL switch in the AUTO position. Oil Pressure Switch A description of each fault and suggested remedies are as follows: High Temperature Switch Oil Drain Fitting No Blinks - ‘Dead’ Unit This condition is caused by a completely dead starting battery.To remedy the problem, remove the 15 Amp fuse and disconnect the battery from the generator.Take the battery to a local battery store for analysis. Replace battery only with a genuine Generac part number 188443. To remedy the low oil pressure condition, fix any obvious oil leak and/or add the recommended oil to the FULL mark on the dipstick. Reset the Fault Detection system as described above. Replace the battery in the battery compartment after it has been fully recharged, connecting the NEGATIVE cable last. Install the 15 Amp fuse. Reset the Fault Detection system as described above. If low oil pressure condition still exists, engine will start, then shut down after about 10 seconds and diagnostic LED will flash. In this case, contact an authorized service facility. 15 Briggs & Stratton Power Products Backup Power System Owner’s Manual Low Voltage This fault is indicated by three blinks.This condition is caused by a restriction in the fuel flow, a broken or disconnected signal lead, a failed alternator winding, the control panel circuit breaker is open, or overloaded circuits in the essential circuit sub-panel. Engine Overspeed This fault is indicated by 6 blinks.This feature protects devices connected to the essential circuit sub-panel by shutting the generator down if its engine happens to run faster than the preset limit.The overspeed fault is detected as follows: Remedy the problem (you may need to contact your installer or Generac Technical Services for assistance), then reset the Fault Detection system, as described above. • If the generator output frequency runs at 72 Hz for five seconds, the generator will shut down. • If the generator output frequency reaches 75 Hz, the generator will shut down instantly. Engine Fail To Start This fault is indicated by four blinks.This feature prevents the generator from damaging itself if it continually attempts to start in spite of another problem, such as no fuel supply. Each time the system is directed to start, the unit will crank for 15 seconds, pause for 15 seconds, crank for 15 seconds, pause for 15 seconds, and repeat. If the system does not begin producing electricity after approximately 90 seconds, the unit will stop cranking and the LED will blink. This condition is caused by a failed engine governor.To remedy the problem, you should contact your installer or Generac Technical Services for assistance.When the problem is corrected, reset the Fault Detection system as described above. Oil Temperature High This fault is indicated by seven blinks.The contacts of the temperature switch (Figure 6) are normally open. If the engine temperature exceeds approximately 140°C (284°F), the fault is detected and the engine shuts down. The most likely cause of this problem is no fuel supply. Check the inside and outside fuel shut off valves to ensure they are fully open. Other causes could be failed spark plug(s), failed engine ignition, or the engine air filter is clogged.You may need to contact your installer for assistance if you can’t remedy these problems.When the problem is corrected, reset the Fault Detection system as described above. Common causes for this condition include running the unit with all access doors removed, obstructed air inlet or exhaust port, or debris in the engine cylinder cooling fins. To resolve the problem, remove any accumulated debris and obstructions and let the engine cool down. Ensure that the Oil Service door and/or the Control Panel door is installed whenever the unit is running.When the problem is corrected, reset the Fault Detection system as described above. Low Frequency This fault is indicated by 5 blinks.This feature protects devices connected to the essential circuit sub-panel by shutting the generator down if its engine runs slower than the preset limit. Power During Fault Condition Whenever the backup power system is in an uncorrected fault condition, the automatic transfer switch is reset to UTILITY POWER.This means that when utility power is restored, utility power will be applied to the essential circuit sub-panel loads.The generator is disconnected from the automatic transfer switch for the duration of any detected fault condition. This condition is caused by a failed engine governor or by excessive loads on the essential circuit sub-panel.To remedy the problem, you may need to contact your installer or Generac Technical Services for assistance.When the problem is corrected, reset the Fault Detection system as described above. 16 Briggs & Stratton Power Products Backup Power System Owner’s Manual Maintenance Schedule The following chart is based on normal engine operation.
