RATINGS: Standby ratings pplyto installations served by a reliable utilftysource. All single-phase units are rated at 1.0 powerfactor. The standby rating is applicable tovariable loadswith 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-3N46/1, BS5514, AS2789, and DIN 6271. GENERAL
GUIDELINES FOR DERATING: ALTITUDE: Derate 4% per 305 m (1000 ft.) elevation above 153 m (500ft.). TEMPERATURE: Derate 2%per 5.5°C (101F) temperature increase above 16°C (601F).
Availability issubjecttochangewithoutnotice. The generatorset manufacturer reserves the rightto change the design or specifications without notice andwithout any obligation or flabilitywhatsoever.
Contact your local Kohler Co. generator distributor for availability.
* The required distance from a structure is dependent on state and local codes. Generator must be located away from doors,.windows, and fresh air intakes. See the Installation manual for guidelines.

Sound Data
Model 20RESD 8 point logarithmic average sound levels are
64 dB(A) during weekly engine exercise and 69 dB(A) during
full -speed generator diagnostics and normal operation. For
comparison to competitor ratings, the lowest sound levels are
62 dB(A) and 67 dB(A) respectively.*
All sound levels are measured at 7 meters with no load.
* Lowest of 8 points measured around the generator. Sound levels at
other points around generator may vary depending on installation
parameters.
