Engines
Commercial grade V-twin engines are standard in all •
models for smooth clean power.
Pressurized lubrication system with spin-on oil lter.•
Generator exercises at operating speed to run complete •
diagnostics on the system.
Converting between natural gas and LP gas is simple •
and easily done in the eld.
Installation
Generator design allows side wall or sub-base •
underground connections.
Easy to use AC and DC terminal blocks make •
connections quick and simple.
Weatherproof Enclosure
Quiet neighbor-friendly operation. •
Fire-retardant sound absorbing foam.•
Galvaneal steel weatherproof housings are strong and •
durable at all temperatures.
All panels are lockable and identically keyed.•
Side panels allow access to the generator for •
maintenance without having to remove or open the roof
exposing the internal components to the elements.
Unique three chamber housing design (see drawing to •
right) increases air ow while reducing noise and heat.
Additional Features
Included battery charger prevents sulfation increasing •
the reliability and service life of the battery. The .75A
multi-stage charger always charges at the proper rate
preventing battery damage.
Fast automatic response to power outages with optional •
transfer switch restores power in less than 30 seconds.
Safety Features
Complete safety shutdowns including high oil temp, low •
oil pressure, low frequency and low voltage protect the
generator and load.
Over current protection by high quality thermal-magnetic •
Square D breaker with Visi-Trip and 1/60 second reaction
time.
Double disc fuel solenoids ensure positive fuel shut-off.•
Steel fuel inlet prevents dangerous cracks. •
CSA approved and ETL listed to UL Standard 2200.•
All models are EPA/CARB compliant.•

Air-Cooled Packaged Standby System
Exclusive three chamber
design controls air movement
through the generator.
Three air intakes provide plenty cooling air. The extra
cooling capacity provides adequate air ow even if
intakes become partially obstructed.
Critical grade mufer reduces
exhaust noise about 25 dba
making the generator very
neighbor-friendly.
Pressurized engine
compartment prevents hot
spots by forcing total air
circulation.
After the engine is shut down
the venting system takes
advantage of convection to
reduce heat soak.
Heat is discharged away from
intakes to prevent recirculation.
Generator Cooling System
Conforms to
UL STD 2200
