STANDARD FEATURES/BENEFITS
OPERATING EFFICIENCY - All units provide high operating
efficiencies and have a minimum AFUE of 80% and SEER of
13.0. All efficiencies exceed legislated minimum levels.
efficiencies and have a minimum AFUE of 80% and SEER of
13.0. All efficiencies exceed legislated minimum levels.
ON SITE FLEXIBILITY - All model sizes share a common,
compact design cabinet in a single footprint. The installer has
the flexibility of setting one curb and placing the proper ton-
nage unit on that curb after the internal load has been deter-
mined. Field convertible duct connections from side shot to
down shot allows the installer to have greater flexibility with
less inventory.

LOWER INSTALLATION COST - Installation time and costs
are reduced by easy power and control wiring connections.
The small base dimension means less space is required on
the ground or roof, plus, the installer can fit this unit between
the wheel wells of full size pick-up truck. All models are well
under 500 pounds.

All units are completely wired, charged with R-22 and tested
prior to shipment. Unique test stations using a new state of the
art computerized process system are used to insure product
quality. Refrigerant charge and component part numbers are
verified via computers at assembly. Vital run test statistics
such as system pressure, motor currents, air velocity and tem-
perature, unit vibration, and gas system safeties are monitored
and recorded by the system to insure unit performance.

Equal size, side supply and return duct connections allows
easy hook-up of ducts to match low crawl spaces without
transition pieces.

UTILITY CONNECTIONS MADE EASY - Gas and electric
utility knockouts are provided through the bottom as well as
the side of the unit. Utility connections can be made quickly
and with a minimum amount of field labor. A field supplied
and field installed electrical disconnect switch must be
installed.

CONVERTIBLE AIRFLOW DESIGN - The bottom duct open-
ings are covered when they leave the factory ready to be
used for a side supply / side return application. If a bottom
supply / bottom return application is desired, you simply
remove the two panels from the bottom of the unit and place
them in the side supply / side return duct openings. No panel
cutting is required and no accessory panel is necessary.
Convertible airflow design allows maximum field flexibility and
minimum inventory.

CONDENSATE PAN - A non-corrosive, long-lasting, water-
tight pan is positioned below the evaporator coil to collect and
drain all condensate. Less collection of stagnate condensate

will build-up. The condensate pan conforms to ASHRAE 62-
89 standards (Ventilation for Acceptable Indoor Air Quality).

CONDENSATE DRAIN - The heavy duty, 3/4 inch NPTI cop-
per connection is more durable over time. The connection is
rigidly mounted to assure proper fit and leak tight seal.

DURABLE FINISH - With a heavy duty cabinet made of pow-
der-painted, galvanized steel the neutral color blends into
surrounding areas. The powdered paint provides a better
paint to steel bond, which resists corrosion and rust creep.
The special primer formulas and glossy finish insures less
fading when exposed to sunlight and offers a more attractive
on site appearance. This paint finish meets ASTM-B117 stan-
dards for 1000 hours salt spray rating. The highest in the
industry.

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
access 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 where 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 inch high base rails
may be removed on location.

MORE ATTRACTIVE APPEARANCE - A single piece Water
Shed top cover containing a top discharge condenser fan
arrangement 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 will not release insulation
fibers into conditioned area.

TOP DISCHARGE - The top discharge condenser fan does
not disrupt neighboring areas or dry-out vegetation surround-
ing 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.

CONDENSER COIL GRILLE - A multi-piece totally enclosed,
rigidly mounted condenser coil grille provides protection from
objects after installation and provides protection during transit.

LOW OPERATING SOUND LEVEL - The upward air flow
carries the normal operating noise up and away from the liv-
ing area. The rigid top panel effectively isolates any motor
sound. Isolator mounted compressor and the rippled fins of
the condenser coil muffle the normal fan motor and compres-
sor operating 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 opti-
mum strength and rigidity.
