MEGA 2500

Extended Life Generator
Owner’s Manual

Danger:

This generator is designed for outdoor use only. Do not use this generator inside

any building or enclosure including the generator compartment of a recreational vehicle

(RV). Fire or an explosion may result. No user performed modifications, including venting

of exhaust and/or cooling ventilation, will eliminate the danger. Also, allow at least two feet

of clearance on all sides of the generator even while operating the unit outdoors.

Danger:

If this unit is used for backup power in the event of a utility power failure, the fol-

lowing step must be taken: Before connecting the generator to an electrical system, open

the main circuit breaker or main switch serving the system, to isolate the generator

system from the electric utility. Failure to isolate the generator and utility systems may

result in damage to the generator and may also result in injury or death to electric utility

workers, due to a backfeed of electrical energy.

This symbol points out  important safety instructions, which, if not followed, could endanger the 

personal safety and/or property of yourself and others. Read and follow all instructions in the

manual before attempting to operate this unit.

Model No.1016–0  (2000 Watt AC Generator)  Part No. B1761  (Revision 0 9/2/97)
