Ambient conditions for rated power output with muffler and RV enclosure, per ISO 8528-1:

- Temperature: 77° F (25° C)

- Altitude: 500 ft (152.4 m), (99 kPa dry)

Typical power output change based on ambient conditions:

- Temperature: Power output decreases 1% for every 10° F (5.5° C) increase

- Altitude: Power output decreases 3.5% for every 1000 ft (305 m) increase

Ratings represent minimums. Actual performance may be significantly higher based on installation and operating conditions.

* Evaporative spec: For trailer applications required to meet Tier III Evaporative Emissions of the California Air

Resources Board.

** Factory OEM packaging

The 60 Hz 100V and 50 Hz sets are not certified for application in North America.

Effective January 1, 2011, gasoline generator sets on trailers, diesel chassis or any other non-motorized mobile

apparatus must have an EVAP generator set, approved tank, EVAP canister, hoses and fittings all meeting the CARB

Tier 3 and EPA phase 3 standards and specifications. This law applies in all 50 states.
