FOR DISTRIBUTION USE ONLY - NOT TO BE USED AT POINT OF RETAIL SALE
These packaged cooling/heating air conditioners are
designed for outdoor installation. Only utility and duct connections are required at the point of installation.
The gas-fired heaters have aluminized steel tubular heat
exchangers and spark to pilot ignition. They are available 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 EERs of
8.6 to 9.2. 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 tonnage unit on that curb after the internal load has been determined. 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
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 openings 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, watertight 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 6289 standards (Ventilation for Acceptable Indoor Air Quality).
CONDENSATE DRAIN - The heavy duty, 3/4 inch NPTI copper connection is more tolerable during installation and 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 powder-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 insure less fading when exposed to sunlight and offers a more attractive on
site appearance. This paint finish meets ASTM-B117 standards 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 does this 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.
CONDENSER COIL GRILLE
rigidly mounted condenser coil grille provides protection from
objects after installation and provides protection duri ng transi t.
LOW OPERATING SOUND LEVEL - The upward air flow
carries 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 condenser coil muffle the normal fan motor and compressor 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 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 diagnostic indicator light and a low voltage
terminal strip. An additional set of pin connectors is also provided to simplify the field interface of external controls. Maten-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 compressor if undesirable operating conditions occur.
EXCLUSIVE COIL DESIGN - Grooved copper tubes and
enhanced aluminum fin construction improves heat transfer
for maximum efficiency and durability.
HEAT EXCHANGERS - Are corrosion-resistant, aluminizedsteel 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 cooling 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 completion 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.
compartment has an additional large panel with a built-in
handle tab. Removing this panel will allow the blower assembly 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
replace any of the components parts for these units. All are
easily obtained from Source 1 or other part houses.
SYSTEM INTEGRATION - Each unit has the internal ability
to integrate an electronic air cleaner or humidifier to work in
conjunction with the base unit.

required to mix the air and gas. These burners are constructed 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 SlipTrack 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. No final field mounting required.
EASY SERVICE ACCESS - A large, single panel covers the
electrical and gas controls makes servicing easy. The blower
