The Kohler® Advantage
• High Quality Power
Kohler home generators provide advanced voltage and
frequency regulation along with ultra -low levels of
harmonic distortion for excellent generator power quality to
protect your valuable electronics.
• Extraordinary Reliability
Kohler is known for extraordinary reliability and
performance and backs that up with a 5-year or 2000-hour
limited warranty.
• Powerful Performance
Exclusive Powerbocst- technology provides excellent
starting power.
• Corrosion -Proof Enclosure
The bold new Kohler design is completely corrosion proof,
even in harsh seaside environments, and is impact -
resistant even at -340 C (-30- F).
• Fast Response
Kohler generators restore power to your home quickly and
reliably.
LPG/Natural Gas
Standard Features
• - RDC2 Controller
o One digital controller manages both the generator set and
transfer switch functions (with optional Model RXT).
o Designed for today's most sophisticated electronics.
o Electronic speed control responds quickly to varying
demand.
o Digital voltage regulation protects your sensitive
electronics from harmonic distortion and unstable power
quality.
o OnCue® Plus Generator Management System for remote
monitoring is included with the generator.
• Kohler Command PRO Engine Features
o Kohler Command PRO®,OHV engine with hydraulic valve
lifters for reliable performance without routine valve
adjustment or lengthy break-in requirements.
o Powerful, reliable air-cooled performance.
o Simple field conversion between natural gas and LPG _
fuels while maintaining emission certification.
• Designed for Easy Installation
o Polymer base eliminates the need for a concrete
mounting pad, reducing installation time and cost.
o Fuel and electrical connections through the enclosure wall
eliminate the need for stub -ups through the bottom.
o Load connection terminal block allows easy field' Wring.
o Designed for outdoor installation only.
• Certifications
o Meets emission regulations for U.S. Environmental
Protection Agency (EPA) with both natural gas and LPG.
Note: CARB does not regulate emergency standby
generators with outputs less than 50 HP.
o UL 2200/cUL listed (60 Hz model).
o CSA certification available (60 Hz model).
o GOST certified (Russia).
o Accepted by the Massachusetts Board of Registration of
Plumbers and Gas Fitters
• Approved for stationary standby applications in locations
served by a reliable utility source.
• 20RESCL models packaged with a Model RXT automatic
transfer switch are available. See page 6 and the Model
RXT ATS specification sheet.
• Warranty
o Standard 5-year/2000-hour limited warranty for on -grid
(standby) applications in locations served by a reliable
utility source.

Generator Set Sound Data
Model 20RESC 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 point 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.
