RATING: All three phases units are rated at 0.8 power factor. All single phase units are rated at 1.0 power factor. STANDBY RATING: Standby ratings apply to installations served by a
reliable utility source. The standby rating is applicable to varying loads for the duration of a power outage. There is no overload capability for this rating. Ratings are in accordance with
ISO-3046-1. Design and specifications are subject to change without notice.
kW rating is based on LPG Fuel and may derate with natural gas.
