each KW generator size, paying close design
attention to the required amount of cooling air
entering the housing, and to ensure adequate hot air
discharge is ample, sound deadening is maximum,
without degrading normal operation of generator set.
The generator housing is all metal, with air openings
and air baffles, strategically located to maximize hot
air discharge and minimize vibrations and sound.
Sound deadening foam is used thru-out the interior of
the metal enclosure.
A particular importance is the interior and exterior
housing finish. All housing parts undergo the
following process:
A) There are (5) separate heated washings to insure a
clean metal part.
B) The 6th stage is a complete emersion into a zinc
phosphate
solution to ensure full corrosion
resistance.
C) Each part is separately E-Coated by complete
tank emersion, to ensure complete coverage
protection in even the most complicated formed
parts.
D) Final finish is a UL Certified powder coat enamel
for outside operation, and a final bake finish,
providing a “Best of Class”, semi-gloss protection,
for years against rust and corrosion.
There are two choices of sound/weather protected
housings:
1) “Standard” housing with standard interior sound
deadening foam and mounted residential grade muffler.
2) “Super-Silent” housing with special interior foam
having damping material included.
3) “Super-Silent” housing also has a “Critical” grade
muffler included with a choice of “Hospital” grade
muffler as an additional upgrade.
4) “Super-Silent” housing also has an additional air chute
(much like the engine end air chute) for increased generator
end silencing.

access doors are
locked, and are
opened with a
common key for
all locks. Notice
the door lock (in
t h e
l o c k e d
position) has
matching dot
s y s t e m i n
the key into lock and turn counterclockwise. Remove
the key and note, the dots are now out of alignment.
Re-insert the key, turn clockwise until dots align, and
it’s in the locked position. All doors are hinged, and
once unlocked, will swing open. All keys are
universal, used on all housing sizes.
All doors have grounding wire, connecting and
grounding door to housing frame. DO NOT
REMOVE these grounding wires. If it becomes
necessary to remove and replace door, be sure to
replace grounding wire and to reuse self grounding
star was-hers, to prevent accidental electrical shock,
if live circuit wires were to touch housing parts.
EXHAUST SYSTEM
The engine end of housed gen-set will have hot
exhaust air discharge from engine muffler, mounted
within housing for complete generator hot air
discharge.
Even though the muffler is safely concealed within
hot air engine exhaust chute, the muffler exhaust
pipe and its accompanying rain cap, extending
straight up from roof, will cause severe burn to the
touch. This “Hot Pipe Burn” warning remains in
effect for 60 minutes after shut-down of generator set.
CORROSION TO GENERATOR AND
HOUSING
Depending on the area of generator installation, will
depend on the amount of attention given to gen-set
cleanliness. Heavy concentration of salt water
exposure (USA Coastal Regions, and Tropics), will
require frequent washings and a final waxing of
generator housing, much like an automobile’s
special care in these areas. Salt corrosion may enter
the generator interior, which may have to be
removed by special detergents. Every 3 months,
spray the engine governor linkage, springs, and
other engine control moving parts with a light spray
coverage of WD-40 to help prevent or prolong
corrosion destruction.
In severe Coastal or Tropical conditions, it is advised
to use aluminum housings, as opposed to steel
housings.
GENERATOR PERFORMANCE
When matching a generator to a specific application,
whether gross intermittent or gross continuous
power is used, it is important to derate this power
output for the following adverse conditions:
