Safety Rules & General Information Section 1: Safety Rules & General Information Introduction Safety Rules Thank you for purchasing this compact, high performance, air-cooled, engine-driven generator. It is designed to automatically supply electrical power to operate critical loads during a utility power failure. This unit is factory installed in an all-weather, metal enclosure intended exclusively for outdoor installation.
Safety Rules & General Information in the spaces provided on the front cover of this manual. WARNING General Hazards Electric shock. Only a trained and licensed electrician should perform wiring and connections to unit. Failure to follow proper installation requirements could result in death, serious injury, and equipment or property damage. (000155a) DANGER Loss of life. Property damage. Installation must always comply with applicable codes, standards, laws and regulations.
Safety Rules & General Information • Inspect the generator regularly, and contact the nearest IASD for parts needing repair or replacement. Exhaust Hazards DANGER Electrocution. Verify electrical system is properly grounded before applying power. Failure to do so will result in death or serious injury. (000152) DANGER Asphyxiation. Running engines produce carbon monoxide, a colorless, odorless, poisonous gas. Carbon monoxide, if not avoided, will result in death or serious injury.
Safety Rules & General Information WARNING WARNING Fire hazard. Use only fully-charged fire extinguishers rated “ABC” by the NFPA. Discharged or improperly rated fire extinguishers will not extinguish electrical fires in automatic standby generators. (000219) WARNING Risk of Fire. Hot surfaces could ignite combustibles, resulting in fire. Fire could result in death or serious injury. (000110) Battery Hazards Electrocution.
Safety Rules & General Information • Always consult local code for additional require- WARNING Environmental Hazard. Always recycle batteries at an official recycling center in accordance with all local laws and regulations. Failure to do so could result in environmental damage, death or serious injury. (000228) Always recycle batteries in accordance with local laws and regulations. Contact your local solid waste collection site or recycling facility to obtain information on local recycling processes.

Unpacking and Inspection Section 2: Unpacking and Inspection General NOTE: Carefully inspect contents for damage after unpacking. Unpack and inspect unit immediately upon delivery to identify any damage which may have occurred in transit. Any claims for shipping damage need to be filed as soon as possible with freight carrier. This is especially important if unit will not be installed for a period of time. Unpacking 1. Remove outer shipping carton. 2. See Figure 2-1. Remove wood frame.
Unpacking and Inspection IMPORTANT NOTE: DO NOT perform next step until generator has been transported to installation site. 4. See Figure 2-3. Remove bolts and pallet brackets (A). Exercise caution when removing generator. Dragging it off pallet will damage base. The unit must be lifted from wooden pallet to remove. NOTE: Bolts and pallet brackets are provided only for shipping purposes and can be discarded after removal.
Unpacking and Inspection Intake Side Panel Removal See Figure 2-6. The intake side panel (A) must be removed to access battery compartment, fuel regulator, and sediment trap. 1. Raise lid and remove front panel. 2. Use a hex key to remove two mounting screws (B) and the hex screw on the L-bracket. 3. Lift intake panel up and away from generator. 4. Inspect for any hidden freight damage. Contact freight carrier if damage is present.
Unpacking and Inspection Generator Main Line Circuit Breaker Parts Shipped Loose See Figure 2-9. The 2-pole circuit breaker (generator disconnect) (A) is rated according to relevant specifications. A E B C D 001803 B A 001810 Figure 2-9. Generator Main Line Circuit Breaker Breaker can be locked in OFF (OPEN) position for security during maintenance or transfer switch service. Use an appropriately-sized padlock (not included) with a shackle long enough to pass through both lock tabs (B).
Unpacking and Inspection Auxiliary Shutdown Switch CAUTION Equipment Damage. The auxiliary shutdown switch is not to be used to power down the unit under normal operating circumstances. Doing so will result in equipment damage. (000399) All generators are equipped with an external means of shutting down the generator which complies with the latest NEC code requirement. The primary generator shutdown sequence is described in Control Panel Startup/ Testing. See Figure 2-11.

Site Selection and Preparation Section 3: Site Selection and Preparation Site Selection Site selection is critical for safe generator operation. It is important to discuss these factors with the installer when selecting a site for generator installation: • • • • • • Carbon monoxide Fire prevention Fresh air for ventilation and cooling Water ingress prevention Proximity to utilities Suitable mounting surface The following pages describe each of these factors in detail.
Site Selection and Preparation Potential CO Entry Points Protect the Structure See Figure 3-1. Generator exhaust can enter a structure through large openings, such as windows and doors. However, exhaust and CO can also seep into the structure through smaller, less obvious openings. Verify structure itself is correctly caulked and sealed to prevent air from leaking in or out. Voids, cracks, or openings around windows, doors, soffits, pipes, and vents can allow exhaust gas to be drawn into the structure.
Site Selection and Preparation Fire Prevention The generator must be installed at a safe distance away from combustible materials. Engine, alternator, and exhaust system components become very hot during operation. Fire risk increases if unit is not correctly ventilated, is not correctly maintained, operates too close to combustible materials, or if fuel leaks exist. Also, accumulations of flammable debris within or outside the generator enclosure may ignite. Distance Requirements See Figure 3-2.
Site Selection and Preparation Fire Codes, Standards, and Guidelines Generator installation must comply strictly with ICC IFGC, NFPA 37, NFPA 54, NFPA 58, and NFPA 70 standards. These standards prescribe the minimum safe clearances around and above the generator enclosure. NFPA 37 NFPA 37 is the The National Fire Protection Association’s standard for the installation and use of stationary combustion engines.
Site Selection and Preparation Fresh Air for Ventilation and Cooling Suitable Mounting Surface Install 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 at a safe distance to protect the unit. See Figure 3-4. Prepare a rectangular area approximately 5 in (127 mm) deep (A) and approximately 3 in (76.2 mm) longer and wider (B) than the generator on all sides.
Site Selection and Preparation This page intentionally left blank.
Generator Placement Section 4: Generator Placement Generator Placement See Figure 4-1. All air-cooled generators come with a composite pad. This composite pad elevates the generator and helps prevent water from pooling around base. Three 3/8 in (or M10) lag bolts (not supplied) are recommended for securing the generator to a concrete pad. NOTE: The top of the generator carton has a template which can be used to mark the concrete pad to pre-drill the mounting holes.

Fuel Conversion / Gas Connections Section 5: Fuel Conversion / Gas Connections Fuel Requirements and Recommendations DANGER Explosion and fire. Fuel and vapors are extremely flammable and explosive. No leakage of fuel is permitted. Keep fire and spark away. Failure to do so will result in death or serious injury. (000192) NOTE: NG is lighter than air and will collect in high areas. LP gas is heavier than air and will settle in low areas. LP gas should only use a vapor withdrawal system.

The number to the right is maximum length (measured in ft / m) allowed for the pipe sizes on top. Pipe sizes are measured by trade size diameter to include any fittings, valves (must be full flow), elbows, tees, or angles. NOTE: See Table B.3.2 in NFPA 54 or Table A.2.
Fuel Conversion / Gas Connections Installing and Connecting Fuel Lines . DANGER Explosion and fire. Fuel and vapors are extremely flammable and explosive. No leakage of fuel is permitted. Keep fire and spark away. Failure to do so will result in death or serious injury. (000192) IMPORTANT NOTE: NG and LP gas are highly volatile substances. Strictly adhere to all safety procedures, codes, standards, and regulations.
Fuel Conversion / Gas Connections Checking Fuel Line Connections Performing Fuel System Leak Test DANGER Checking Fuel Pressure Proceed as follows to check fuel pressure at regulator in the generator. 1.
