RATINGS: Standby ratings apply to installations served by a reliable utility source. All single-phase units are rated at 1.0 power factor. The standby rating is applicable to variable loads with an average

load factor of 80% for the duration of the power outage. No overload capacity is specified at this rating. Ratings are in accordance with ISO- 3046/1, BS5514, AS2789, and DIN 6271. GENERAL

GUIDELINES FOR DERATING: ALTITUDE: Derate 4% per 305 m (1000 ft.) elevation above 153 m (500 ft.). TEMPERATURE: Derate 1.5% per 5.5_C(10_F) temperature increase above 16_C

(60_F). Availability is subject to change without notice. The generator set manufacturer reserves the right to change the design or specifications without notice and without any obligation or liability

whatsoever. Contact your local Kohler Co. generator distributor for availability.

* Check the appliance manufacturer’s specifications for actual power requirements. Consult a Kohlerr Power Sy stems professional to calculate your exact residential power system

requirements.
