NOMENCLATURE
DESCRIPTION
These packaged cooling/heating air conditioners are
designed for outdoor installation. Only utility and duct con-
nections are required at the point of installation.
The gas-fired heaters have aluminized steel tubular heat
exchangers and hot surface to pilot ignition. They are avail-
able in natural gas with field conversion to propane.
STANDARD FEATURES/BENEFITS
OPERATING EFFICIENCY - All units provide high operating
efficiencies and have a minimum AFUE of 80% and SEERS of
12.0 and 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-410A 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 temperature, 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.
FAN SYSTEM - All models operate over a wide range of
design conditions with a constant CFM, electrically commu-
tated (ECM) fan motor. These units easily match all types of
applications and provide greater on site flexibility to match
comfort requirement. These models have 2 cooling speeds
and a single heating speed. The cooling speed is factory set
and can be field adjusted to a second speed. The heating
speed is factory set to maintain mid point rise at the units
heating input. It cannot be field adjusted. This allows maxi-
mum comfort conditions.
SIMPLE CONTROL CIRCUIT - A low voltage printed circuit
board contains a diagnostic indicator light and a low voltage
terminal strip. An additional set of pin connectors is also pro-
vided to simplify the field interface of external controls. Mate-
n-lock plug connectors are used. The electrical control box is
not located in the compressor compartment. The controls are
mounted on a Control-Tilt control panel to allow the access
cover to be removed for trouble shooting and maintenance
without affecting the normal system operating pressures. All
wiring internal to the unit is color/number coded.
PROTECTED COMPRESSOR - The compressor is internally
protected against high pressure and temperature. This is
accomplished by the simultaneous operation of high pressure
relief valve and a temperature sensor which protect the com-
pressor if undesirable operating conditions occur.
PRESSURE SWITCHES- High pressure and low pressure/
loss of charge switches standard in all units. When abnormal
conditions are sensed through the pressure switches, the unit
will lock out preventing any further operation until reset or
problem is corrected.
EXCLUSIVE COIL DESIGN - Grooved copper tubes and
enhanced aluminum fin construction improves heat transfer
for maximum efficiency and durability.
HEAT EXCHANGERS - Are corrosion-resistant, aluminized-
steel tubular construction to provide long-life, trouble-free
operation. The unique blow-through design also assures that
condensate does not collect in humid areas when in the cool-
ing cycle. This adds to longer heat exchanger life and higher
long term efficiencies.
POST PURGE INDUCED DRAFT COMBUSTION - Exhausts
combustion products from the heat exchanger upon comple-
tion of the heating cycle to prolong the heat exchanger life.
SELF DIAGNOSTIC FAN CONTROL MODULE - Due to this
self diagnostic control, less on site time is required to trouble
shoot these units.
HOT SURFACE TO PILOT IGNITION - Provides faster heat
delivery. This ignition is highly reliable, durable and elimi-
nates nuisance lockouts. Also assures starts in damp condi-
tions.
MULTI PORT IN-SHOT BURNERS - No field adjustment is
required to mix the air and gas. These burners are con-
structed of high-grade corrosion-resistant, aluminized-steel.
LOW MAINTENANCE - Long life, permanently lubricated
condenser and evaporator fan motor bearings need no
annual maintenance adding greater reliability to the unit.
Blower assembly can be easily cleaned by the unique Slip-
Track slide-out blower assembly.
SECURED SERVICE ACCESS PORTS - Protected, exter-
nally mounted, re-usable service access ports are provided
on both the high and low lines for ease of evacuating and
charging the system. No final field mounting required.

Unitary Products Group 5
EASY SERVICE ACCESS - A large, single panel covers the
electrical and gas controls makes servicing easy. The blower
compartment has an additional large panel with a built-in
handle tab. Removing this panel will allow the blower assem-
bly to slide-out for easy removal for maintenance and ease of
trouble shooting.
REPLACEMENT PARTS - The installer requires no special
training to replace any of the components of these units and
does not need to maintain an inventory of unique parts.
SYSTEM INTEGRATION - Each unit has the internal ability
to integrate an electronic air cleaner or humidifier to work in
conjunction with the base unit.
