Before using this generator, you are advised to read the manual in its entirety and fully understand its contents.
In case of an emergency, the owner operator is responsible for proper and safe use of the electric generator system. The manufacturer strongly suggest that the owner operator read the Owner’s Manual in its entirety and understand all operating instructions before using the electrical standby generator. If not properly adhered to, damage can occur to the system causing fire, electrical shock and even death.
• Despite the safety design features of this generator, operating this system improperly, and neglecting routine maintenance can cause possible injury or death. Allow only certified and licensed personnel to install, operate and maintain this system. • Potentially lethal voltages are generated by these generators. Make sure all steps are taken to render the machine safe before attempting to work or service the generator system.
ELECTRICAL HAZARDS • 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.
POSSIBLE 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 area surrounding the generator clean and free from debris. • Gaseous fluids such as natural gas (NG) and liquid propane gas (LPG) are extremely EXPLOSIVE. Install the fuel supply system according to applicable fuel-gas codes.
Only qualified electricians or contractors should attempt such installations, which must comply strictly with applicable local and state codes, standards and regulations. Uncrating and Initial Inspection After uncrating, carefully inspect the contents for any visible damage. Do not tilt the machine more than 30 degrees. Try to avoid transporting on uneven ground. Violent shaking and vibration during transportation may affect the unit.
First Step! Contact your local building inspector or City Hall to be aware of all federal, state and local codes that could impact the installation. Secure all required permits before starting the project. Carefully read and follow all procedures and safety precautions detailed in the installation guide. If any portion of the installation manual, technical manual or other factory-supplied documents is not completely understood, contact your local authorized dealer for assistance.
than 5 feet than 5 feet 2. Place the unit so air vents won’t become clogged with leaves, grass, snow or debris. Make sure exhaust fumes will not enter the building through eaves, windows, ventilation fans or other air intakes. Build a rectangular form out of 2”X6 wooden studs. Dig an area approximately 4 inches deep and about 4 to 6 inches, longer and wider than the footprint of the generator. Place wooden frame in hole leaving approximately 2” above ground.
Engine Prestart and Preparation All necessary installation and maintenance must be conducted and performed by authorized licensed personnel. Before starting engine for the first time, engine oil and radiator coolant must be added. An initial fluid inspection and pre-check is recommended before starting genset for the first time or when unit has been in operation for over 20 hours. It can also be used as a quick review of all fluids. Check all of the following items before running system for the first time.
2. Cooling System Use only automotive grade antifreeze and distilled water in cooling system. Do not use tap water, or water that contains salt or alkalis! Using non-distilled water creates scale in the radiator, causing corrosion and premature wear. You must check and maintain all fuel, lubricant and coolant levels. Not doing so will accelerate and shorten the life of the standby system.
