* Maximum wattage and current are subject to and limited by such factors as fuel Btu content, ambient temperature, altitude, engine power and condition, etc.
Maximum power decreases about 3.5 percent for each 1,000 feet above sea level; and also will decrease about 1 percent for each 6 C (10 F) above 16 C (60 F)
ambient temperature.
** Load current values shown for 120 volts are maximum TOTAL values for two separate circuits. The maximum current in each circuit must not exceed the value
stated for the 240 volts.
*** Circuits to be moved must be protected by same size breaker. For example, a 15 amp circuit in the main panel must be a 15 amp circuit in the transfer switch.

This unit is tested in accordance to UL 2200 standards with an operating temperature of 20° F (-29° C) to 122°F. (50° C). For
areas where temperatures fall below 32° F (0° C), a cold weather kit is highly recommended. When operated above 77° F (25° C)
there may be a decrease in engine power. (Please reference the engine specifications section).
