STANDARD FEATURES and BENEFITS - continued
DURABLE FINISH - With a heavy duty cabinet made of
powder-painted, galvanized steel the neutral color blends into
surrounding areas. The powered paint, provides a better paint
to steel bond, which resists corrosion and rust creep. The spe-
cial primer formulas and glossy earth tone finish insure less
fading when exposed to sunlight and offers a more attractive
on site appearance. This paint finish exceeds ASTM-B117
standards for 750 hours salt spray rating, the highest in the in-
dustry.
FULL PERIMETER BASE RAILS - The easily removable
base rails provide a solid foundation for the entire unit and
protects the unit during shipment. The rails provide fork lift ac-
cess from all sides, and rigging holes are also provided so that
an overhead crane can be used to place the units on a roof.
On applications when the unit is placed on a pad, the base will
keep the unit off the pad to deter corrosion. On applications
where height is limited, the
moved on location.
MORE ATTRACTIVE APPEARANCE - A single piece "Water
Shed" top cover containing a top discharge condenser fan ar-
rangement requires less square footage on installation and
provides a wider variety of installations. The one piece design
adds greater water integrity. Rounded corners with water drip
edges add to the attractive appearance. The cabinet panels
have a non-fibrous insulation that reduces insulation fibers
into conditioned area.
TOP DISCHARGE - The top discharge condenser fan does
not disrupt neighboring areas and does not dry-out vegetation
surrounding the unit. The warm air from the top mounted fan is
blown up away from the structure and any landscaping. This
allows compact location on multi-unit applications.
OUTDOOR COIL GRILLE - A multi-piece totally enclosed,
rigidly mounted outdoor coil grille provides protection from ob-
jects and personal after installation and provides protection
during transit and installation.
LOW OPERATING SOUND LEVEL - The upward air flow car-
ries the normal operating noise up and away from the living
area. The rigid top panel effectively isolates any motor sound.
Isolator mounted compressor and the rippled fins of the con-
denser coil muffle the normal fan motor and compressor oper-
ating sounds. The unique formed base pan also aids in sound
alterations with it's "Super-Structure" design. This design
strategically places embossments in the pan for optimum
strength and rigidity.

FAN SYSTEM - All models operate over a wide range of design
conditions with a 3-speed direct-drive fan motor. These units
easily match all types of applications and provides greater on
site flexibility to match comfort requirement.
SIMPLE CONTROL CIRCUIT - A low voltage printed circuit
board contains a low voltage terminal strip. The electrical con-
trol box is not located in the compressor compartment. All wir-
ing internal to the unit is color/number coded.
CONTROLS - Reliable time-temperature defrost control pro-
vides defrost including field selectable time periods between
cycles (30, 60 and 90 minutes). factory set at 30 minutes. De-
frost control also provides an "X" terminal to provide a 24 volt
signal for room thermostat "LED" indication of unit lockout,
plus built in 5 minute anti-short cycle protection.
PROTECTED COMPRESSOR - The compressor is internally
protected against high pressure and temperature. This is ac-
complished by the simultaneous operation of high pressure
relief valve and a temperature sensor which protect the com-
pressor if undesirable operating conditions occur.
EXCLUSIVE COIL DESIGN - Grooved copper tubes and en-
hanced aluminum fin construction improves heat transfer for
maximum efficiency and durability.
LOW MAINTENANCE - Long life, permanently lubricated
condenser and evaporator fan motor bearings need no an-
nual maintenance adding greater reliability to the unit. Blower
assembly can be easily removed for cleaning by the unique
"Slip Track" slide-out blower assembly.
SECURED SERVICE ACCESS PORTS - Protected, externally
mounted, re-usable service access ports are provided on both
the high and low lines for ease of evacuating and charging the
system.
EASY SERVICE ACCESS - A large, single hinged panel cov-
ers the electrical controls and makes servicing easy. The
blower compartment has an additional large panel with a built-
in handle tab. Removing this panel will allow the blower as-
sembly to slide-out for easy removal for maintenance and
ease of trouble shooting.
REPLACEMENT PARTS - The installer has no need to carry
an inventory of unique parts or needs special training to re-
place any of the components parts for these units. All are eas-
ily obtained from Source 1 or other major part houses.
