GENERAL HAZARDS • For safety reasons, the manufacturer recommends that this equipment be installed, serviced and repaired by a 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. • The engine exhaust fumes contain carbon monoxide, which can be DEADLY. This dangerous gas, if breathed in sufficient concentrations, can cause unconsciousness or even death. Do NOT alter or add to the exhaust system or do anything that might render the system unsafe or in noncompliance with applicable codes and standards. 2 • Install a battery operated carbon monoxide alarm indoors, according to manufacturer's instructions/recommendations. • Adequate, unobstructed flow of cooling and ventilating air is critical to 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. The generator MUST be installed and operated outdoors only. • 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. • 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 contact the nearest Dealer for parts needing repair or replacement. • 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, then remove the POSITIVE, POS or (+) cable. When reconnecting the cables, connect the POSITIVE cable first, the NEGATIVE 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. EXHAUST HAZARDS • Generator engine exhaust contains DEADLY carbon monoxide, an odorless, colorless poisonous gas. Breathing carbon monoxide can cause: dizziness, throbbing temples, nausea, muscular twitching, headache, vomiting, weakness and sleepiness, inability to think clearly, fainting, unconsciousness or even death. If you experience any carbon monoxide poisoning symptoms, move into fresh air and immediately seek medical attention. • NEVER use inside a home or a garage EVEN IF doors and windows are open. Only use OUTSIDE and far away from windows, doors and vents. 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 does the standby generator when it is in operation. Avoid contact with bare wires, terminals, connections, etc., while the unit is running. Ensure all appropriate covers, guards and barriers are in place, secured and/or locked 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. Safety Rules • The National Electrical Code (NEC) requires the frame and external electrically conductive parts of the generator to be connected to an approved earth ground. Local electrical codes also may require proper grounding of the generator electrical system. • After installing this home standby electrical system, the generator may crank and start at any time without warning. When this occurs, load circuits are transferred to the STANDBY (generator) power source. To prevent possible injury if such a start and transfer occur, always set the generator’s AUTO/OFF/MANUAL switch to its OFF position before working on equipment and remove the 15A fuse from the generator control panel. • 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 • For fire safety, the generator must be installed and maintained properly. Installation 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 in accordance with the manufacturer’s instructions and recommendations. Following proper installation, do nothing that might alter a safe installation and render the unit in noncompliance with the aforementioned codes, standards, laws and regulations. • Keep a fire extinguisher near the generator at all times. Extinguishers rated “ABC” by the National Fire Protection Association are appropriate for use on the standby electric system. Keep the extinguisher properly charged and be familiar with its use. Consult the local fire department with any questions pertaining to fire extinguishers. EXPLOSION HAZARDS • 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. • Gaseous fluids such as natural gas and liquid propane (LP) gas are extremely EXPLOSIVE. Install the fuel supply system according to applicable fuel-gas codes. Before placing the home standby electric system into service, fuel system lines must be properly purged and leak tested according to applicable code. After installation, inspect the fuel system periodically for leaks. No leakage is permitted.

The combination transfer switch and load center is pre-wired with a two foot and 30 foot conduit. Circuit breakers for emergency circuit connections are included (if equipped). • This UL listed, 2-pole switch is rated at 100 or 200 AC amperes at 250 volts maximum. The 100 Amp transfer switch is for indoor use only. The 200 Amp transfer switch is for indoor/ outdoor use (if equipped). 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 electrical system from the utility distribution system when the generator is operating (NEC 700, 701 & 702). Failure to isolate an electrical system by such means will result in damage to the generator and also may result in injury or death to utility power workers due to backfeed of electrical energy. If any loss or damage is noted at time of delivery, have the person(s) making the delivery note all damage on the freight bill or affix their signature under the consignor's memo of loss or damage. If a loss or damage is noted after delivery, separate the damaged materials and contact the carrier for claim procedures. “Concealed damage” is understood to mean damage to the contents of a package that is not in evidence at the time of delivery, but is discovered later. To properly open the roof, press down on the center top lip and release the latch. If pressure is not applied from the top, the roof may appear stuck. Always verify that the side lock is unlocked before attempting to lift the roof. 4 PROTECTION SYSTEMS Unlike an automobile engine, the generator may have to run for long periods of time with no operator present to monitor engine conditions. For that reason, the engine is equipped with the following systems that protect it against potentially damaging conditions: 1. Low Oil Pressure Sensor 6. Low Battery 2. High Temperature Sensor 7. Under-frequency 3. Overcrank 8. Undervoltage 4. Overspeed 9. Overvoltage 5. RPM Sensor 10. Internal Failure There are readouts on the control panel to notify personnel that one of these failures has occurred. There is a Status message on the display that displays when all of the conditions described in the "Ready to Run" section are true. 1.3 NEC REQUIREMENTS Local code enforcement may require that AFCI’s be incorporated into the transfer switch distribution panel. The Transfer Switch provided with this generator has a distribution panel that will accept AFCI’s. Siemens Part No. Q115AF - 15A or Q120AF - 20A can be obtained from a local electrical wholesaler and will simply replace any of the single pole circuit breakers supplied in the Transfer Switch distribution panel. 1.4 EMISSION INFORMATION The Environmental Protection Agency requires that this generator complies with exhaust emission standards. This generator is certified to meet the applicable EPA emission levels.

Battery Compartment 5 General Information 1.7 READY TO RUN The "Ready to Run" on the display is ready when all of the following conditions are true: 1. 2. 3. The AUTO/OFF/MANUAL switch is set to the AUTO position. The utility voltage being supplied to the unit is being sensed by the PCB. If the utility sense voltage is not connected to the unit or if it is below approximately 150-160 volts AC, then the system will display the message "No Utility Present". This indicates that if the AUTO/OFF/MANUAL switch is placed in the Auto position, the generator will start. No alarms are present, for example, low oil pressure, high temperature, etc. 1.8 FUEL REQUIREMENTS AND RECOMMENDATIONS With LP gas, use only the vapor withdrawal system. This type of system uses the vapors formed above the liquid fuel in the storage tank. The engine has been fitted with a fuel carburetion system that meets the specifications of the 1997 California Air Resources Board for tamper-proof dual fuel systems. The unit will run on natural gas or LP gas, but it has been factory set to run on natural gas. Should the primary fuel need to be changed to LP gas, the fuel system needs to be reconfigured. See the reconfiguring the Fuel System section for instructions on reconfiguration of the fuel system. Recommended fuels should have a Btu content of at least 1,000 Btus per cubic foot for natural gas; or at least 2,520 Btus per cubic foot for LP gas. Ask the fuel supplier for the Btu content of the fuel. Required fuel pressure for natural gas is five (5) inches to seven (7) inches water column (0.18 to 0.25 psi); and for liquid propane, 10 inches to 12 inches of water column (0.36 to 0.43 psi). The primary regulator for the propane supply is NOT INCLUDED with the generator. NOTE: All pipe sizing, construction and layout must comply with NFPA 54 for natural gas applications and NFPA 58 for liquid propane applications. Once the generator is installed, verify that the fuel pressure NEVER drops below four (4) inches water column for natural gas or 10 inches water column for liquid propane. Prior to installation of the generator, the installer should consult local fuel suppliers or the fire marshal to check codes and regulations for proper installation. Local codes will mandate correct routing of gaseous fuel line piping around gardens, shrubs and other landscaping to prevent any damage. Special considerations should be given when installing the unit where local conditions include flooding, tornados, hurricanes, earthquakes and unstable ground for the flexibility and strength of piping and their connections. 6 Use an approved pipe sealant or joint compound on all threaded fitting. All installed gaseous fuel piping must be purged and leak tested prior to initial start-up in accordance with local codes, standards and regulations. 1.9 FUEL CONSUMPTION Nat.

Verify that gas meter is capable of providing enough fuel flow to include household appliances. 1.9.1 BTU FLOW REQUIREMENTS - NATURAL GAS BTU flow required for each unit based on 1000 BTU per cubic foot. • 9kW — 156,000 BTU/Hour • 15kW — 261,000 BTU/Hour • 18kW — 294,000 BTU/Hour (LP) gas are highly explosive. Even propane the slightest spark can ignite such fuels and Gaseous fuels such as natural gas and liquid 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. NOTE: A minimum of one approved manual shut-off valve must be installed in the gaseous fuel supply line. The valve must be easily accessible. Local codes determine the proper location. General Information 1.10 RECONFIGURING THE FUEL SYSTEM To reconfigure the fuel system from NG to LP, follow these steps: NOTE: Figure 1.5 - 15 & 20kW, GT-990/GT-999 (Airbox Cover Removed) Fuel Selection Lever - "In" Position for Natural Gas Fuel The primary regulator for the propane supply is NOT INCLUDED with the generator. A fuel pressure of 10 to 12 inches of water column (0.36 to 0.43 psi) to the fuel inlet of the generator MUST BE SUPPLIED. 1. 2. Open the roof.

This dannThe gerous gas, if breathed in sufficient con- centrations, can cause unconsciousness or even death. This generator must be installed properly, in strict compliance with applicable codes and standards. Following installation, do nothing that might render the system unsafe or in noncompliance with such codes and standards. Operate the generator outdoors ONLY. • Keep exhaust gases from entering a confined area through windows, doors, ventilation, crawl spaces or other openings (Figure 1.7). • It is highly recommended that carbon monoxide detector(s) be installed indoors according to the manufacturer's instructions/recommendations. 7 General Information Figure 1.7 – Generator Clearances • The generator must be mounted safely per applicable codes and the manufacturer's specifications. Do NOT alter or add to the exhaust system, or do anything that might render the exhaust system unsafe or in noncompliance with applicable codes and standards. 1.11.1 GENERATOR Install the generator set, in its protective enclosure, outdoors, where adequate cooling and ventilating air is always available (Figure 1.7). Consider these factors: • The installation of the generator must comply strictly with NFPA 37, NFPA 54, NFPA 58, and NFPA 70 standards. • 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. This unit must be installed in accordance with current applicable NFPA 37 and NFPA 70 standards; as well as any other federal, state and local codes for minimum distances from other structures. DO NOT install under wooden decks or structures unless there is at least four (4) feet of clearance above the generator, three (3) feet of clearance on sides and front, and 18 inches of clearance at back of unit. • Install the unit where rain gutter down spouts, roof run-off, landscape irrigation, water sprinklers or sump pump discharge does not flood the unit or spray the enclosure, including any air inlet or outlet openings. • Install the unit where services will not be affected or obstructed, including concealed, underground or covered services such as electrical, fuel, phone, air conditioning or irrigation. • Where strong prevailing winds blow from one direction, face the generator air inlet openings to the prevailing winds. • Install the generator as close as possible to the fuel supply, to reduce the length of piping. • Install the generator as close as possible to the transfer switch. REMEMBER THAT LAWS OR CODES MAY REGULATE THE DISTANCE AND LOCATION. • The genset must be installed on a level surface. The base frame must be level within two (2) inches all around. • The generator is typically placed on pea gravel or crushed stone. Check local codes if a concrete slab is required. If a concrete base slab is required, all federal, state and local codes should be followed. Special attention should be given to the concrete base slab which should exceed the length and width of the generator by a minimum of six (6) inches (0.152 meters) on all sides. 8 1.11.2 INSTALLATION GUIDELINES FOR STATIONARY AIR-COOLED 10, 15 AND 20 KW GENERATORS The National Fire Protection Association has a standard for the installation and use of stationary combustion engines. That standard is NFPA 37 and its requirements limit the spacing of an enclosed generator set from a structure or wall (Figure 1.8). NFPA 37, Section 4.1.4, Engines Located Outdoors. Engines, and their weatherproof housings if provided, that are installed outdoors shall be located at least 5 ft. from openings in walls and at least 5 ft. from structures having combustible walls. A minimum separation shall not be required where the following conditions exist: 1. The adjacent wall of the structure has a fire resistance rating of at least 1 hour. 2. The weatherproof enclosure is constructed of noncombustible materials and it has been demonstrated that a fire within the enclosure will not ignite combustible materials outside the enclosure. Annex A — Explanatory Material A4.1.4 (2) Means of demonstrating compliance are by means of full scale fire test or by calculation procedures. Because of the limited spaces that are frequently available for installation, it has become apparent that exception (2) would be beneficial for many residential and commercial installations. With that in mind, the manufacturer contracted with an independent testing laboratory to run full scale fire tests to assure that the enclosure will not ignite combustible materials outside the enclosure. The criteria was to determine the worst case fire scenario within the generator and to determine the ignitability of items outside the engine enclosure at various distances. The enclosure is constructed of non-combustible materials and the results and conclusions from the independent testing lab indicated that any fire within the generator enclosure would not pose any ignition risk to nearby combustibles or structures, with or without fire service personnel response. General Information Figure 1.8 – Installation Guidelines No windows or openings in the wall permitted within 5 feet from any point of the generator. 60 inches 36 inches These guidelines are based upon fire testing of the generator enclosure and the manufacturer’s requirement for air flow for proper operation.

For adequate maintenance and airflow clearance, the area above the generator should be at least 4 feet with a minimum of 3 feet at the front and ends of the enclosure. This would include trees, shrubs and vegetation that could obstruct airflow. See the diagram on the reverse of this page and the installation drawing within the owner’s manual for details. Generator exhaust contains DEADLY carbon monoxide gas. This dangerous gas can cause unconsciousness or death. Do not place the unit near windows, doors, fresh air intakes (furnaces, etc.) or any openings in the building or structure, including windows and doors of an attached garage. OFF position, the generator can crank toanditsstart as soon as the battery cables are If the AUTO/OFF/MANUAL switch is not set connected. If the utility power supply is not turned off, sparking can occur at the battery posts and cause an explosion. 1.12 BATTERY REQUIREMENTS See the Specifications section for correct battery size and rating. 1.13 BATTERY INSTALLATION Fill the battery with the proper electrolyte fluid if necessary and have the battery fully charged before installing it. Before installing and connecting the battery, complete the following steps: 1. Set the generator's AUTO/OFF/MANUAL switch to OFF. 2. Turn off utility power supply to the transfer switch. 3. Remove the 7.5A fuse from the generator control panel. Battery cables were factory connected at the generator (Figure 1.9). Connect cables to battery posts as follows: 4. 5. 6. Connect the red battery cable (from starter contactor) to the battery post indicated by a positive, POS or (+). Connect the black battery cable (from frame ground) to the battery post indicated by a negative, NEG or (—). Install the battery post covers (included). NOTE: Dielectric grease should be used on battery posts to aid in the prevention of corrosion. NOTE: Damage will result if battery connections are made in reverse. NOTE: In areas where temperatures regularly fall below 32° F (0° C) it is recommended that a pad type battery heater be installed to aid in cold climate starting. 10 1.14 THE BATTERY battery is capable of exploding. A battery presents a risk of electrical shock and high short circuit current. The following Do not dispose of the battery in a fire. The precautions are to be observed when working on batteries: • Remove the 7.5A fuse from the generator control panel. • Remove watches, rings or other metal objects. • Use tools with insulated handles. • Wear rubber gloves and boots. • Do not lay tools or metal parts on top of the battery. • Disconnect charging source prior to connecting or disconnecting battery terminals. not open or mutilate the battery. Released electrolyte has been known to nDo be harmful to the skin and eyes, and to be toxic. electrolyte is a dilute sulfuric acid that is harmful to the skin and eyes. It is electrinThe cally 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. Post Installation Start-up and Adjustments • Spilled electrolyte is to be washed down with an acid neutralizing agent. A common practice is to use a solution of 1 pound (500 grams) bicarbonate of soda to 1 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 procedures are to be followed: • DO NOT SMOKE when near the battery. • DO NOT cause flame or spark in battery area. • Discharge static electricity from body before touching the battery by first touching a grounded metal surface. 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 and the 7.5A fuse is removed from the generator control panel, or sparking may occur at the battery posts as the cables are attached and cause an explosion. Servicing of the battery is to be performed or supervised by personnel knowledgeable of batteries and the required precautions. Keep unauthorized personnel away from batteries. n See the Specifications section for the correct size and rating when replacing the battery. Have these procedures performed at the intervals specified in the “Service Schedule.” A negative ground system is used. Battery connections are shown on the wiring diagrams. Make sure the battery is correctly connected and terminals are tight. Observe battery polarity when connecting the battery to the generator set. 1.15 BATTERY CHARGER NOTE: The battery charger is integrated into the control module in all models. It operates as a "Smart Charger" which ensures output is continually optimized to promote maximum battery life and charging levels are at safe conditions. 2.1 ACTIVATE THE GENERATOR When battery power is applied to the generator during the installation process, the controller will light up. However, the generator still needs to be activated before it will automatically run in the event of a power outage. Activating the generator is a simple one time process that is guided by the controller screen prompts. Once the product is activated, the controller screen will not prompt you again, even if you disconnect the generator battery. After obtaining your activation code, please complete the following steps at the generator’s control panel in the Activation Chart. 2.2 BEFORE INITIAL START-UP NOTE: These units have been run and tested at the factory prior to being shipped and do not require any type of break-in. NOTE: This unit comes filled with oil from the factory. Check the oil level and add the appropriate amount if necessary. Before starting, complete the following: 1. Set the generator’s main circuit breaker to its OFF (or OPEN) position. 2. Set the generator's AUTO/OFF/MANUAL switch to the OFF position. 3. Turn OFF all breakers on the load center of the transfer box (T1 and T2). 4. Turn OFF all loads connected to the transfer switch terminals T1 and T2. 5. Check the engine crankcase oil level and, if necessary, fill to the dipstick FULL mark with the recommended oil. Do not fill above the FULL mark. 6. Check the fuel supply. Gaseous fuel lines must have been properly purged and leak tested in accordance with applicable fuel-gas codes. All fuel shutoff valves in the fuel supply lines must be open. During initial start up only, the generator may exceed the normal number of start attempts and experience an “over crank” fault (See the "Overcrank" section). This is due to accumulated air in the fuel system during installation. Reset the control board and restart up to two more times, if necessary. If unit fails to start, contact the local dealer for assistance. NOTE: There is a warning on the LCD display when the battery needs service. operate the engine with the oil level below the “Add” mark on the dipstick. Doing nNever this could damage the engine. 11 Post Installation Start-up and Adjustments ACTIVATION CHART CHOOSE LANGUAGE TROUBLESHOOTING Display Reads: Language English Escape Use ARROW keys to scroll to desired language.

Set generator’s main circuit breaker to its OFF (or OPEN) position. Check that the AUTO/OFF/MANUAL switch is set to OFF. Turn OFF the utility power supply to the transfer switch, using means provided (such as a utility main line circuit breaker). Manually set the transfer switch to the UTILITY position, i.e., load terminals connected to the utility power source side. Turn ON the utility power supply to the transfer switch, using the means provided (such as a utility main line circuit breaker). Set the generator's main circuit breaker to its ON (or CLOSED) position. Set the AUTO/OFF/MANUAL switch to AUTO. The system is now ready for automatic operation. Turn OFF the utility power supply to the transfer switch. With the AUTO/OFF/MANUAL switch at AUTO, the engine should crank and start when the utility source power is turned OFF after a 10 second delay. After starting, the transfer switch should connect load circuits to the standby side after a five (5) second delay. Let the system go through its entire automatic sequence of operation. With the generator running and loads powered by generator AC output, turn ON the utility power supply to the transfer switch. The following should occur: • After about 15 seconds, the switch should transfer loads back to the utility power source. • About one minute after re-transfer, the engine should shut down. 3.1 CONTROL PANEL INTERFACE 3.1.1 USING THE AUTO/OFF/MANUAL SWITCH (FIGURE 3.1) the switch set to AUTO, the engine may crank and start at any time without warning. nWith Such automatic starting occurs when utility 1. 2. 3. power source voltage droops 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 switch to OFF and remove the fuses before working on or around the generator or transfer switch. Then, place a “DO NOT OPERATE” tag on the generator panel and on the transfer switch. “AUTO” Position – Selecting this switch activates fully automatic system operation. It also allows the unit to automatically start and exercise the engine every seven days with the setting of the exercise timer (see the Setting the Exercise Timer section). “OFF” Position – This switch position shuts down the engine. This position also prevents automatic operation. “MANUAL” Position – Set the switch to MANUAL to crank and start the engine. Transfer to standby power will not occur unless there is a utility failure. 3.1.2 SETTING THE EXERCISE TIMER This generator is equipped with an exercise timer. Once it is set, the generator will start and exercise every seven days, on the day of the week and at the time of day specified. During this exercise period, the unit runs for approximately 12 minutes and then shuts down. Transfer of loads to the generator output does not occur during the exercise cycle unless utility power is lost. Figure 3.1 – 10, 15 & 20kW Generator Control Panel MAIN FUSE 7.5 AMP AUTO OFF MANUAL Escape 14 Enter Operation INSTALLATION ASSISTANT Display Interface Menus Interconnect System Self Test Feature (follow the on-screen prompts) The LCD display is organized as detailed below: Upon power up, this controller will go through a system self test which will check for the presence of utility voltage on the DC circuits. This is done to prevent damage if the installer mistakenly connects AC utility power sense wires into the DC terminal block. If utility voltage is detected, the controller will display a warning message and lock out the generator, preventing damage to the controller. Power to the controller must be removed to clear this warning. Utility voltage must be turned on and present at the N1 and N2 terminals inside the generator control panel for this test to be performed and pass. NOTE: DAMAGE CAUSED BY MISWIRING OF THE INTERCONNECT WIRES IS NOT WARRANTABLE! This test will be performed each time the controller is powered up. Upon first power up of the generator, the display interface will begin an installation assistant. The assistant will prompt the user to set the minimum settings to operate. These settings are simply: Current Date/Time and Exercise Day/Time. The maintenance intervals will be initialized when the exercise time is entered (Figure 3.1). The exercise settings can be changed at any time via the "EDIT" menu (see Appendix, "Menu System"). If the 12 volt battery is disconnected or the fuse removed, the Installation Assistant will operate upon power restoration. The only difference is the display will only prompt the customer for the current Time and Date. IF THE INSTALLER TESTS THE GENERATOR PRIOR TO INSTALLATION, PRESS THE “ENTER” KEY TO AVOID SETTING UP THE EXERCISE TIME. THIS WILL ENSURE THAT WHEN THE CUSTOMER POWERS UP THE UNIT, HE WILL STILL BE PROMPTED TO ENTER AN EXERCISE TIME. NOTE: The exerciser will only work in the AUTO mode and will not work unless this procedure is performed. The current date/time will need to be reset every time the 12 volt battery is disconnected and then reconnected, and/or when the fuse is removed. Low Speed Exercise 15 and 20kW units will run at 2,400 RPM on Low Speed Exercize. • The “Home” page, this page is the default page which will be displayed if no keys are pressed for 30 seconds.

This page displays the following options: HISTORY; STATUS; EDIT; AND DEBUG. (See the Appendix - "Menu System".) 3.2 AUTOMATIC TRANSFER OPERATION To select automatic operation, do the following: 1. Make sure the transfer switch main contacts are set to their UTILITY position, i.e., loads connected to the utility power source (Figure 3.1). 2. Be sure that normal UTILITY power source voltage is available to transfer switch terminal lugs N1 and N2 (Refer to the Electrical Data section). 3. Set the generator’s AUTO/OFF/MANUAL switch to AUTO. 4. Set the generator’s main circuit breaker to its ON (or CLOSED) position. With the preceding steps complete, the generator will start automatically when utility source voltage drops below a preset level. After the unit starts, loads are transferred to the standby power source. Refer to the Sequence of Automatic Operation section. 3.3 SEQUENCE OF AUTOMATIC OPERATION 3.3.1 UTILITY FAILURE Initial Conditions: Generator in Auto, ready to run, load being supplied by utility source. When utility fails (below 60% of nominal), a 10 second (optionally programmable) line interrupt delay time is started. If the utility is still gone when the timer expires, the engine will crank and start. Once started, a five (5) second engine warmup timer will be initiated. When the warm-up timer expires, the control will transfer the load to the generator. If the utility power is restored (above 80% of nominal) at any time from the initiation of the engine start until the generator is ready to accept load (5 second warm-up time has not elapsed), the controller will complete the start cycle and run the generator through its normal cool down cycle; however, the load will remain on the utility source. 15 Operation 3.3.2 CRANKING The system will control the cyclic cranking as follows: 16 second crank, seven (7) second rest, 16 second crank, seven (7) second rest followed by three (3) additional cycles of seven (7) second cranks followed by seven (7) second rests. Choke Operation 1. 2. The 990/999cc engines have an electric choke in the air box that is automatically controlled by the electronic control board. The 530cc engines have an electric choke on the divider panel air inlet hose that is automatically controlled by the electronic control board. Failure to Start This is defined as any of the following occurrences during cranking: 1. Not reaching starter dropout within the specified crank cycle. Starter dropout is defined as four (4) cycles at 1,000 RPM. 2. Reaching starter dropout, but then not reaching 2200 RPM within 15 seconds. In this case the control board will go into a rest cycle for seven (7) seconds, then continue the rest of the crank cycle. During a rest cycle the start and fuel outputs are de-energized and the magneto output is shorted to ground. Cranking Conditions The following notes apply during cranking cycle. 1. Starter motor will not engage within five (5) seconds of the engine shutting down. 2. The fuel output will not be energized with the starter. 3. The starter and magneto outputs will be energized together. 4. Once the starter is energized the control board will begin looking for engine rotation. If it does not see an RPM signal within three (3) seconds it will shut down and latch out on RPM sensor loss. 5. Once the control board sees an RPM signal it will energize the fuel solenoid, drive the throttle open and continue the crank sequence. 6. Starter motor will disengage when speed reaches starter dropout. 7. If the generator does not reach 2200 RPM within 15 seconds, re-crank cycle will occur. 8. If engine stops turning between starter dropout and 2200 RPM, the board will go into a rest cycle for seven (7) seconds then re-crank (if additional crank cycles exist). 9. Once started, the generator will wait for a hold-off period before starting to monitor oil pressure and oil temperature (refer to the Alarm Messages section for hold-off times). 10. During Manual start cranking, if the Mode switch is moved from the Manual position, the cranking stops immediately. 11. During Auto mode cranking, if the Utility returns, the cranking cycle does NOT abort but continues until complete. Once the engine starts, it will run for one (1) minute, then shut down. 16 3.3.3 LOAD TRANSFER The transfer of load when the generator is running is dependent upon the operating mode as follows: 1. Manual • Will not transfer to generator if utility is present. • Will transfer to generator if utility fails (below 65% of nominal for 10 consecutive seconds. • Will transfer back when utility returns for 15 consecutive seconds. The engine will continue to run until removed from the Manual mode. 2. Auto • Will start and run if Utility fails for 10 consecutive seconds. • Will start a five (5) second engine warm-up timer. • Will not transfer if utility subsequently returns. • Will transfer to generator if utility is still not present. • Will transfer back to utility once utility returns (above 75% of nominal) for 15 seconds. • Will transfer back to utility if the generator is shut down for any reason (such as the switch is in the OFF position or a shutdown alarm. • After transfer, will shut down engine after one (1) minute cool-down time. 3. Exercise • Will not exercise if generator is already running in either Auto or Manual mode. • During exercise, the controller will only transfer if utility fails during exercise for 10 seconds, and will switch to Auto mode. 3.3.4 UTILITY RESTORED Initial Condition: Generator supplying power to customer load. When the utility returns (above 80% of nominal), a 15 second return to utility timer will start. At the completion of this timer, if the utility supply is still present and acceptable, the control will transfer the load back to the utility and run the engine through a one (1) minute cool down period and then shut down. If utility fails for three (3) seconds during this cool down period, the control will transfer load back to the generator and continue to run while monitoring for utility to return. 3.4 MANUAL TRANSFER OPERATION 3.4.1 TRANSFER TO GENERATOR POWER SOURCE To start the generator and activate the transfer switch manually, proceed as follows: 1. 2. 3. Set the generator’s AUTO/OFF/MANUAL switch to OFF. Set the generator’s main circuit breaker to its OFF (or OPEN) position. Turn OFF the utility power supply to the transfer switch using the means provided (such as a utility main line circuit breaker).

A hasp is provided so the owner can secure the compartment with their own padlock. Check local codes in the area. 3.5.1 MAIN CIRCUIT BREAKER This is a 2-pole breaker rated according to the Specifications section. 3.5.2 EXTERIOR READY LIGHTS • Green LED ‘Ready’ light is on when utility is present and switch is in AUTO indicating the generator is ready and when the generator is running. • Red LED ‘Alarm’ light is on when the generator is OFF or a fault is detected. (See the Protections Systems section.) • Yellow LED ‘Maintenance’ light (See the Protections Systems section.) 3.5.3 5. 6. 7. To crank and start the engine, set the AUTO/OFF/MANUAL switch to MANUAL. Let the engine stabilize and warm up for a few minutes. Set the generator’s main circuit breaker to its ON (or CLOSED) position. The standby power source now powers the loads. 3.4.2 TRANSFER BACK TO UTILITY POWER SOURCE When utility power has been restored, transfer back to that source and shut down the generator. This can be accomplished as follows: 1. 2. 3. 4. Set the generator’s main circuit breaker to its OFF (or OPEN) position. Let the engine run for a minute or two at no-load to stabilize the internal temperatures. Set the generator’s AUTO/OFF/MANUAL switch to its OFF (or OPEN) position. The engine should shut down. Check that utility power supply to the transfer switch is turned OFF. 120 VAC GFCI OUTLET & 15 AMP BREAKER These models are equipped with an external, 15 amp, 120 volt, GFCI convenience outlet that is located in a compartment on the right side of generator (Figure 1.3). When the generator is running, in the absence of utility power, this outlet may also be used to power items outside your home such as lights or power tools. This outlet may also be used when utility power is present by running the generator in manual mode. This outlet does not provide power if the generator is not running. This outlet is protected by a 15 amp circuit breaker in the same compartment as the outlet. (Do not use when the generator is running in exercise mode.)

They must be cleared before the alarm message goes away. The alarm log records each occurrence (see Appendix - "Menu System"). Low Oil Pressure (Shutdown Alarm) A five (5) second delay on start-up and seven (7) second delay once the engine is running. This switch (Figure 3.5) has normally closed contacts that are held open by engine oil pressure during operation. Should the oil pressure drop below the five (5) PSI range, switch contacts close and the engine shuts down. The unit should not be restarted until oil level is verified. High Engine Temperature (Shutdown Alarm – Auto Reset) A 10 second delay on start-up and one (1) second delay before shutdown. Auto reset when the condition clears and restart the engine if a valid start signal is still present. Oil Drain Hose Over Speed (Shutdown Alarm) 4320 RPM for three (3) seconds or 4500 RPM immediately. This feature protects the generator from damage by shutting it down if it happens to run faster than the preset limit. This protection also prevents the generator from supplying an output that could potentially damage appliances connected to the generator circuit. Contact the nearest Dealer if this failure occurs. RPM Sense Loss (Shutdown Alarm) During cranking, if the Control Board does not see a valid RPM signal within three (3) seconds, it will shut down and lock out on RPM sense loss. While engine is running, if RPM signal is lost for one (1) second the Control Board will shut the engine down, wait 15 seconds, then re-crank the engine. If no RPM signal is detected within the first three (3) seconds of cranking, the Control Board will shut the engine down and latch out on RPM sensor loss. If the RPM signal is detected, the engine will start and run normally. If the RPM signal is subsequently lost again, the Control Board will try one more re-crank attempt before latching out and displaying the RPM sensor failure message. This switch’s contacts (Figure 3.5) close if the temperature should exceed approximately 144° C (293° F), initiating an engine shutdown. Once the oil temperature drops to a safe level the switch’s contacts open again. Under-frequency (Shutdown Alarm) Over Crank (Shutdown Alarm) Internal Fault (Shutdown Alarm) This occurs if the engine has not started within the specified crank cycle. (See "Cranking" section.) This alarm cannot be cleared, call service dealer. NOTE: The oil drain hose may be routed in the opposite direction as shown in figure. 18 After starting, if the generator stays under frequency for more than 30 seconds it will shut down. The under-frequency setting is 55 Hz. Undervoltage (Shutdown Alarm) If the generator voltage falls below 85% of nominal for more than 10 seconds, it shuts down. Maintenance Overvoltage (Shutdown Alarm) If the generator voltage rises above 110% of rating for greater than three (3) seconds, an alarm will be issued and the unit will shut down. If the generator voltage rises above 130% of rating for greater than 0.2 seconds, an alarm will be issued and the unit will shut down. Clear Alarm Clear the alarm by setting the AUTO/OFF/MANUAL switch to the OFF position. Press the ENTER key to unlatch any active fault and clear the corresponding alarm message. 3.6.2 COMMON ALARM RELAY The common alarm relay will be activated if there is a shutdown alarm. It will not activate on warnings or indicate that the AUTO/ OFF/MANUAL switch is in the OFF position. The OFF position will clear the alarms and the relay. The relay will not be used to indicate a generator is not activated. The common alarm terminals are wired to a set of potential-free (dry) contacts on the Nexus contoller board. These Normally Open (N.O.) contacts close when an alarm condition occurs and are used to activate a remote signaling device. The circuit is rated for a maximum of 130mA at 24 VDC. 3.6.3 WARNINGS Second Priority (Non-latching) Displayed on the control panel and the external yellow LED. Warnings automatically clear when the monitored condition goes away. Warnings are recorded in the alarm log. Warnings cannot cause shutdowns. NOTE: Since most maintenance alerts will occur at the same time (most have two (2) year intervals), only one will appear on the display at any one time. Once the first alert is cleared, the next active alert will be displayed. 4.1 FUSE 4.2 CHECKING THE ENGINE OIL LEVEL The 7.5 amp fuse on the control panel protects the DC control circuit against overload (Figures 3.1 and 3.2). This fuse is wired in series with the battery output lead to the panel. If this fuse element has melted open, the engine will not be able to crank or start. Replace this fuse using only an identical 7.5 amp replacement fuse. Whenever the fuse is removed or replaced, the exercise timer needs to be reset. For oil capacities, see the Specifications section. For engine oil recommendations, see the Engine Oil Recommendations section. When power outages necessitate running the generator for extended periods of time, the oil level should be checked daily. To check the engine oil level, proceed as follows (Figures 4.1 and 4.2): 1. 2. 3. 4. Low Battery The Control Board monitors battery voltage and displays a warning if the battery voltage falls below 11.9 volts for one (1) minute. Warning is automatically cleared if the battery voltage rises above 12.4 volts. Battery voltage is not monitored during the crank cycle. Exercise Set Error If the exercise period becomes corrupted, a warning message will be displayed. This message will only clear when the exercise period is reset. 3.6.4 MAINTENANCE ALERTS 5. 6. 7. If the generator is running during a utility outage, first turn OFF all associated loads running in the residence. Second, turn the generator's main circuit breaker to the OFF position. Move the AUTO/OFF/MANUAL switch to the OFF position. Remove the dipstick and wipe it dry with a clean cloth. Completely insert the dipstick; then, remove it again. The oil level should be at the dipstick “Full” mark. If necessary, add oil to the “Full” mark only. DO NOT FILL ABOVE THE “FULL” MARK. Install the dipstick. Reset the AUTO/OFF/MANUAL switch to its original position. If the generator was running during a utility outage, first turn the generator's main circuit breaker back to the ON position. Second, turn ON needed loads in the residence. operate the engine with the oil level below the “Add” mark on the dipstick. Doing nNever this could damage the engine.

Adjust the gap to 0.76 mm (0.030 inch) for 10 and 20kW; and 1.02 mm (0.040 inch) for 15kW by carefully bending the ground electrode (Figure 4.8). Figure 4.8 – Setting the Spark Plug Gap Filter 21 Maintenance 4.6 BATTERY MAINTENANCE The battery should be inspected per the "Service Schedule" section. The following procedure should be followed for inspection: 1. Inspect the battery posts and cables for tightness and corrosion. Tighten and clean as necessary. Check the battery fluid level of unsealed batteries and, if necessary, fill with Distilled Water Only. Do not use tap water in batteries. Have the state of charge and condition checked. This should be done with an automotive-type battery hydrometer. 2. 3. A battery presents a risk of electrical shock and high short circuit current. The following Do not dispose of the battery in a fire. The battery is capable of exploding. precautions are to be observed when working on batteries: • Remove the 7.5A fuse from the generator control panel. • Remove watches, rings or other metal objects. • Use tools with insulated handles. • Wear rubber gloves and boots. • Do not lay tools or metal parts on top of the battery. • Disconnect charging source prior to connecting or disconnecting battery terminals.

Important: If feeling uncomfortable about doing this procedure or the proper tools are not available, please contact the Dealer for service assistance. This is a very important step to ensure longest life for the engine. To check valve clearance: • The engine should be cool before checking. If valve clearance is 0.002" - 0.004" (0.05 - 0.1mm), adjustment is not needed. • Remove spark plug wires and position wires away from plugs. • Remove spark plugs. • Make sure the piston is at Top Dead Center (TDC) of its compression stroke (both valves closed). To get the piston at TDC, remove the intake screen at the front of the engine to gain access to the flywheel nut. Use a large socket and socket wrench to rotate the nut and hence the engine in a clockwise direction. While watching the piston through the spark plug hole. The piston should move up and down. The piston is at TDC when it is at its highest point of travel. To adjust valve clearance (if necessary), (Figure 4.9): • Make sure the engine is at 60° to 80° F. • Make sure that the spark plug wire is removed from the spark plug and out of the way. • Remove the four screws attaching the valve cover. • Loosen the rocker jam nut. Use a 10mm allen wrench to turn the pivot ball stud while checking clearance between the rocker arm and the valve stem with a feeler gauge. Correct clearance is 0.002-0.004 inch (0.05-0.1 mm). NOTE: Hold the rocker arm jam nut in place as the pivot ball stud is turned. Maintenance Figure 4.10 – Cooling Vent Locations When valve clearance is correct, hold the pivot ball stud in place with the allen wrench and tighten the rocker arm jam nut. Tighten the jam nut to 174 in/lbs. torque. After tightening the jam nut, recheck valve clearance to make sure it did not change. • Install new valve cover gasket. • Re-attach the valve cover. Figure 4.9 - Valve Clearance Adjustment Jam Nut Pivot Ball Stud Rocker Arm Valve Stem 4.9 ATTENTION AFTER SUBMERSION If the generator has been submerged in water, it MUST NOT be started and operated. Following any submersion in water, have a Dealer thoroughly clean, dry and inspect the generator. If the structure (ex. home) has been flooded, it should be inspected by a certified electrician to ensure there won't be any electrical problems during generator operation or when utility is returned. 4.10 CORROSION PROTECTION Periodically wash and wax the enclosure using automotive type products. Frequent washing is recommended in salt water/coastal areas. Spray engine linkages with a light oil such as WD-40. NOTE: Start all four screws before tightening or it will not be possible to get all the screws in place. Make sure the valve cover gasket is in place. 4.11 OUT OF SERVICE PROCEDURE • Install spark plugs. • Re-attach the spark plug wire to the spark plug. • Repeat the process for the other cylinder. If the generator cannot be exercised every seven days, and will be out of service longer than 90 days, prepare the generator for storage as follows: 4.8 COOLING SYSTEM Air inlet 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 a rapid shut down. (See Figure 4.10 for vent locations.) Make sure the doors and roof are in place during operation as running the generator with them removed can effect cooling air movement. hot and remains hot after shutdown. High The exhaust from this product gets extremely grass, weeds, brush, leaves, etc. must remain clear of the exhaust. Such materials may ignite and burn from the heat of the exhaust system. 4.11.1 REMOVAL FROM SERVICE 1. 2. Start the engine and let it warm up.

(Generac), are pleased to explain your recordkeeping requirements for compliance with Subpart JJJJ – Standards of Performance for Stationary Spark Ignition Internal Combustion Engines as listed in the Electronic Code of Federal Regulations Title 40 Part 60. As the engine purchaser/ owner who operates and maintains their certified emergency stationary engine and emission control system according to applicable emission related guidelines as specified in this Owner’s Manual you are required to meet the following notification and recordkeeping requirements to demonstrate compliance. 1.) Maintain documentation that the engine is certified to meet emission standards. 2.) Recordkeeping of maintenance conducted. 3.) Recordkeeping of the provision allowing natural gas engines to operate using propane for a maximum of 100 hours per year as an alternate fuel solely during emergency operations provided the engine is not certified to operate on propane. 4.) Meet all compliance notifications submitted to the purchaser/owner and maintain all supporting documentation. 5.) Recordkeeping of hours of operation, including what classified the operation as emergency and how many hours are spent for non-emergency operation. For emergency engines greater than or equal to 130 HP, recordkeeping of hours of operation begins January 1, 2011. For emergency engines less than 130 HP, recordkeeping of hours of operation begins January 1, 2009; Engines are equipped with non-resettable hour meters to facilitate recordkeeping. Specific Air Quality Management or Air Pollution Control Districts may have different and additional record keeping/ reporting requirements. Your permit to construct and/or operate the engine may be contingent upon compliance with those requirements. Check with your local Air Quality Management or Air Pollution Control District for specific requirements. Emergency stationary internal combustion engines (ICE) may be operated for the purpose of maintenance checks and readiness testing, provided that the tests are recommended by Federal, State or local government, Generac, or the insurance company associated with the engine. Maintenance checks and readiness testing of such units is limited to 100 hours per year. There is no time limit on the use of emergency stationary ICE in emergency situations. The purchaser/owner may petition the Administrator for approval of additional hours to be used for maintenance checks and readiness testing, but a petition is not required if the owner maintains records indicating that Federal, State, or local standards require maintenance and testing of emergency ICE beyond 100 hours per year. Emergency stationary ICE may operate up to 50 hours per year in non-emergency situations, but those 50 hours are counted towards the 100 hours per year provided for maintenance and testing. The 50 hours per year for non-emergency situations cannot be used for peak shaving or to generate income for a facility to supply power to an electric grid or otherwise supply power as part of a financial arrangement with another entity. For purchaser/owner of emergency engines, any operation other than emergency operation, maintenance and testing, and operation in non-emergency situations for 50 hours per year, as permitted in this section is prohibited. If you operate and maintain your certified emergency stationary SI internal combustion engine and emissions control systems in accordance to the specifications and guidelines in this Owner’s Manual EPA will not require engine performance testing. If not, your engine will be considered non-certified and you must demonstrate compliance according to Subpart JJJJ – Standards of Performance for Stationary Spark Ignition Internal Combustion Engines as listed in the Electronic Code of Federal Regulations Title 40 Part 60. Emission-Related Installation Instructions Your certified emergency stationary engine has pre-set emission control systems or components that require no adjustment.
