Symbol Meaning Explosion Safety Messages WARNING This product can expose you to chemicals including used engine oil, which is known to the State of California to cause cancer, and carbon monoxide, which is known to the State of California to cause birth defects or other reproductive harm. For more information go to www.P65Warnings.ca.gov. Electric Shock Toxic Fumes WARNING Failure to read and obey the operator’s manual, all warnings, and operating instructions could result in death or serious injury.
WARNING Battery electrolyte fluid contains acid and is extremely caustic. Contact with battery contents could cause severe chemical burns. • DO NOT open or mutilate the battery • Wear protective goggles, rubber apron, rubber boots and rubber gloves. • Immediately wash electrolyte from skin with water. • If electrolyte contacts eyes, immediately flush with water and seek medical attention. • Spilled electrolyte is to be washed down with an acid neutralizing agent.
WARNING With the battery connected, the generator may crank and start without warning resulting in death or serious injury. • Before servicing, stop the generator and disconnect the negative (-) cable at the battery. WARNING Hazardous Voltage - Contact with power lines could cause electric shock or burns, resulting in death or serious injury. • If lifting or hoisting equipment is used, DO NOT contact any power lines. • DO NOT lift or move generator without assistance.
• Use generator only for intended uses. • If you have questions about intended use, contact your authorized dealer. • Operate generator only on level surfaces. • Adequate, unobstructed flow of cooling and ventilating air is critical to correct generator operation. • The access panels/doors must be installed whenever the unit is running. • DO NOT expose generator to excessive moisture, dust, dirt, or corrosive vapors. • Remain alert at all times while working on this equipment.

Reduce the Risk of Carbon Monoxide Poisoning N o R tf ep o r ro du ct io n The arrows in the figure below point to potential points of entry for Carbon Monoxide Gas. All fossil fuel burning equipment, such as standby generators (A), contains carbon monoxide (CO) gas in the engine exhaust (H). CO gas is odorless, colorless and tasteless and is unlikely to be noticed until a person is overcome. CO gas can kill you so it is required that the following is included as part of the installation.
n N o R tf ep o r ro du ct io • Nearby structures may be exposed to the engine exhaust (H) from the generator (A) and must be considered when installing the standby generator. • Wind and air currents should be taken into consideration when positioning the generator (A). Place the generator in an area where winds will carry the exhaust gas (H) away from any potentially occupied building or structure. • DO NOT place the standby generator (A) in any area where leaves or debris can accumulate.

(B) Standby enclosure must be at least 5 ft (1.5 m) from windows, doors, any wall opening, shrubs or vegetation over 12 inches (30.5 cm) in height. (C) Exhaust outlet of standby enclosure must have at least 5 ft (1.5 m) minimum clearance from any structure, shrubs, trees or any kind of vegetation. (D) Standby enclosure must have a minimum of 5 feet (1.5 m) overhead clearance from any structure, overhang or trees. (E) Standby enclosure must have a minimum of 18 inches (45.
n N o R tf ep o r ro du ct io Anchoring and Wind Rating Concrete Anchoring of Unit to Poured or Existing Slab To achieve the listed wind rating, the generator must be installed in strict compliance with this installation manual. The product components must be of the material specified and all screws must be installed in accordance with the applicable provisions and the anchor manufacturer’s published installation instructions.
Electrical and Fuel Inlet Locations The 3/4 inch N.P.T. fuel inlet connector (A) and electrical inlet locations (B) are shown below. N o R tf ep o r ro du ct io n A ½ inch knock-out is provided for the electrical inlet. This inlet may be enlarged or supplemented to accommodate a maximum conduit size of 1-½ inches. Make sure that the installed conduit(s) enter the unit in zone (C) as shown in the drawing below so that they properly enter the electrical box and do not interfere with the fully opened roof.
2. Remove the two bolts (F) that secure the panel (G) to the unit. 3. Lift up on the panel (G) and remove it. Note: Fuse holder (E) is located behind the battery panel (G). Attach battery panel (G): 1. Put the panel (G) in the unit. 2. Attach the panel (G) with the two bolts (F). Fuel Installation Plan WARNING Propane and Natural Gas are extremely flammable and explosive, which could cause burns, fire or explosion resulting in death or serious injury.
• Use a pipe sealant or joint compound approved for use with NG/LP on all threaded fittings to reduce the possibility of leakage. NOTICE Keep thread sealant out of the gas piping to prevent component part damage. • Installed piping must be properly purged and leak tested, in accordance with applicable codes and standards.

For Natural Gas fuel pressure levels of 3.5 - 5" W.C., replace the regulator assembly with service kit 6331-00 (available at your local service dealer). Power Loss Air density is less at high altitudes, resulting in less available engine power. Engine power will decrease by 3.5% for each 1,000 feet (300 m) above sea level and by 1% for each 10° F (5.6°C) above 77°F (25°C). Generators located in these conditions must have their transfer switch adjusted appropriately for this power decrease.

• Torque circuit breaker connections to 45 in-lb [5 Newton meter]. Generator AC System Connection A single-phase, three-wire AC connection system is used in the generator. The stator assembly consists of a pair of stationary windings with two leads brought out of each winding. The junction of leads 22 and 33 forms the neutral lead, as shown schematically and as a wiring diagram. NOTICE Neutral is not bonded to ground at generator.
For operation in temperatures below 30°F (-1°C), the use of fully synthetic oil (minimum API SJ) of viscosity 5W30 is required. Dimensions (Maximum) BCI Size 26 or BCI Size BCI Size 24 51 Battery WARNING With the battery connected, the generator may crank and start without warning resulting in death or serious injury. WARNING Storage batteries give off explosive hydrogen gas during recharging. Slightest spark could ignite hydrogen and cause explosion, resulting in death or serious injury.
n WARNING N o R tf ep o r ro du ct io Initial Start-Up (No Load) Exhaust heat/gases could ignite combustibles causing a fire, resulting in death or serious injury. • Remove all combustible materials from in and around the generator compartment. The unit has been set-up for NG operation at the factory. Fuel conversion, if needed, must be completed prior to performing these steps. See Fuel Conversion.
