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).  
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 spark to pilot ignition. They are available in  
natural gas with field conversion to propane.  
CONDENSATE DRAIN - The heavy duty, 3/4 inch NPTI cop-  
per 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.  
STANDARD FEATURES/BENEFITS  
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 insure less fad-  
ing 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.  
OPERATING EFFICIENCY - All units provide high operating  
efficiencies and have a minimum AFUE of 80% and SEER of  
up to 12.4. 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.  
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.  
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 prod-  
uct 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 mon-  
itored and recorded by the system to insure unit perfor-  
mance.  
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.  
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.  
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.  
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.

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 pro-  
vides greater on site flexibility to match comfort requirement.  
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.  
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.  
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.  
FILTER / FRAME KIT - The filter rack is suitable for either 1"  
or 2" filters. (1" filter is supplied).  
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.  
FIELD-INSTALLED ACCESSORIES  
PROPANE CONVERSION KIT - Kit includes burner orifices,  
gas valve conversion and installation instructions necessary

self diagnostic control, less on site time is required to trouble  
shoot these units.  
SINGLE ENTHALPY SENSOR - Sensor replaces dry bulb  
sensor standard in economizer kit. Provides improved econo-  
mizer operation by sensing the dry bulb temperature from  
outdoors plus the enthalpy content of the outdoor air.  
SPARK TO PILOT IGNITION - Provides faster heat delivery.  
This ignition is highly reliable, durable and eliminates nui-  
sance lockouts.  
DUAL ENTHALPY SENSOR - Additional sensor to single  
enthalpy sensor. Sensor senses both the return air tempera-  
ture dry bulb and humidity in conjunction with the single  
enthalpy to determine the most economical mix. Single  
Enthalpy sensor also required.

neither LR or ASCT are present, wire 202/Y is connected  
to M1 coil as shown.  
TYPICAL WIRING DIAGRAM NOTES  
1. All field wiring to be accomplished following city, local  
and/or national codes in effect at time of installation of  
this unit.  
7. Shunt contact also used with crankcase heater.  
(optional)  
8. Unit factory wired for low or medium speed indoor blower  
operation. To change motor speed, connect speed tap  
wires from indoor blower motor, per Detail A (Figure 19).  
Tape unused speed tap wires to prevent shorting and  
secure.  
2. Caution: Label all wires prior to disconnection when ser-  
vicing controls. Wiring errors can cause improper and  
dangerous operation. If any of the wire as supplied with  
this unit must be removed it must be replaced with type  
105°C, 600V wire or equivalent clearly renumbered for  
identification. Verify proper operation after servicing.  
9. Select indoor blower speed to remain within the temper-  
ature rise range on the nameplate in heating.  
3. Motors inherently protected.  
4. Factory wired for 460V operation.
