FEATURE/BENEFITS
One-piece heating and cooling unitswithlowsoundlevels,easy
installation, low maintenance, and dependable performance.
EASY INSTALLATION — Factory-assembled package is a
compact, fully self-contained, combination gas heating/electric
cooling unit that is pre-wired, pre-piped, and pre-charged for
minimum installation expense.
These units are available in a variety of standard and optional
heating/cooling size combinations with voltage options to meet
residential and light commercial requirements. Units are lightweight and install easily on a rooftop or at ground level. The
high tech composite basepan eliminates rust problems associated with ground level applications.
CONVERTIBLE DUCT CONFIGURATION — Unit is designed
for easy use in either downflow or horizontal applications. Each
unit is easily converted from horizontal to downflow with addition
of two accessory duct covers.
EFFICIENT OPERATION
High-Efficiency Design with SEER (Seasonal Energy Effi-
ciency Ratios) of 12.0 and AFUE (Annual Fuel Utilization Efficiency) rating as high as 81%.
Energy-Saving, Direct Spark Ignition saves gas by operating
only when the room thermostat calls for heating. Standard units
are furnished with natural gas controls. A low cost field-installed
kit for propane conversion is available for all units.
All Units meet the California maximum oxides of nitrogen
(NOx) emission requirements when accessory kit is used.

DURABLE, DEPENDABLE COMPONENTS
Compressors are designed for high efficiency. Each compres-
sor is hermetically sealed against contamination to help promote longer life and dependable operation. Each compressor
also has vibration isolation to provide quieter operation. All
compressors have internal high pressure and overcurrent
protection.
Monoport Inshot Burners produce precise air-to-gas mixture,
which provides for clean and efficient combustion. The large
monoport on the inshot (or injection type) burners seldom, if
ever, requires cleaning. All gas furnace components are accessible in one compartment.
Turbo-tubular™ Heat Exchangers are constructed of aluminized steel for corrosion resistance and optimum heat transfer
for improved efficiency. The tubular design permits hot gases to
make multiple passes across the path of the supply air.
In addition, dimples located on the heat exchanger walls force
the hot gases to stay in close contact with the walls, improving
heat transfer.
Direct-Drive Multi-Speed, PSC (Permanent Split Capacitor)
Blower Motor is standard on all 583A models.
Direct-Drive, PSC Condenser-Fan Motors are designed to
help reduce energy consumption and provide for cooling operation down to 40 F outdoor temperature. MotormasterT II low ambient kit is available as a field-installed accessory.
Corporate Thermostats include the Time GuardT II anti-short
cycle protection circuitry. If an Original Equipment Manufacture
(OEM) thermostat is used the Time Guard II field-installed antishort cycle kit must be used.
Refrigerant System is designed to provide dependability. Liquid refrigerant strainers are used to promote clean, unrestricted
operation. Each unit leaves the factory with a full refrigerant
charge. Refrigerant service connections make checking operating pressures easier.
Evaporator and Condenser Coils are computer-designed for
optimum heat transfer and cooling efficiency. The evaporator
coil is fabricated from copper tube and aluminum fins and is located inside the unit for protection against damage. The condenser coil is internally mounted on the top tier of the unit. A
FIOP (Factory-Installed Option) metal louvered grille is available
on all models. Copper fin coils and pre-coated fin coils are available from the factory by special order. These coils are recommended in applications where aluminum fins are likely to be
damaged due to corrosion. They are ideal for seacoast
applications.
Low Sound Ratings ensure a quiet indoor and outdoor environment with sound ratings as low as 7.2 bels. (See page 3.)
Easy to Service Cabinets provide easy single-panel accessibility to serviceable components during maintenance and installation. The basepan with integrated drain pan provides easy
ground level installation with or without a mounting pad. Convenient handholds are provided to manipulate the unit on the

jobsite. A nesting feature ensures a positive basepan to roof
curb seal when the unit is roof mounted. A convenient
3
⁄4-in.
wide perimeter flange makes frame mounting on a rooftop easy.
Downflow Operation is easily provided in the field to allow ver-
tical ductwork connections. The basepan utilizes knockout style
seals on the bottom openings to ensure a positive seal in the
horizontal airflow mode.
Integrated Gas Control (IGC) Board provides safe and efficient control of heating and simplifies troubleshooting through
its built-in diagnostic function.
Cabinets are constructed of heavy-duty, phosphated, zinccoated prepainted steel capable of withstanding 500 hours in
salt spray. Interior surfaces of the evaporator/heat exchanger
compartment are insulated with cleanable semi-rigid insulation
board, which keeps the conditioned air from being affected by
the outdoor ambient temperature and provides improved indoor
air quality. (Conforms to American Society of Heating, Refrigeration and Air Conditioning Engineers No. 62P.) The sloped
drain pan minimizes standing water in the pan.

71,910 Btuh with an input of 88,000 Btuh.
IV DETERMINE FAN SPEED AND POWER REQUIRE-
MENTS AT DESIGN CONDITIONS.
Before entering the air delivery tables, calculate the total
static pressure required. From the
Coil Pressure Drop Table, and the Filter Pressure Drop
table on page 16, find at 1200 cfm:
External static pressure 0.1 in. wg
Wet Coil 0.1 in. wg
Filter 0.2 in. wg
Total static pressure 0.4 in. wg
Enter the table for Dry Coil Air Delivery — Horizontal and
Downflow Discharge on page 15. For 208 v operation, deduct 10% from value given. At 0.4 ESP (external static
pressure), the fan will deliver 1213 cfm at medium speed.
The fan speed should be set at medium speed.

2. Ductwork — Secure downflow discharge ductwork to roof
curb. For horizontal discharge applications, attach ductwork
to unit with flanges.
3. To convert a unit to downflow discharge — Units are
equipped with factory-installed inserts in the downflow
openings. Remove the inserts similar to removing an electrical knock-out. Use an accessory duct cover to seal the horizontal discharge openings in the unit. Units installed in
horizontal discharge orientation do not require duct covers.
4. Airflow — Units are draw-thru in the Cooling mode and
blow-thru in the Heating mode.
5. Maximum cooling airflow — To minimize the possibility of
condensate blow-off from the evaporator, airflow through the
units should not exceed 450 cfm/ton.
6. Minimum cooling airflow — The minimum cooling airflow is
350 cfm/ton.
7. Minimum ambient operating temperature — All standard
units have a minimum ambient operating temperature of
40 F. With accessory low ambient temperature kit, units can
operate at temperatures down to 0° F.

CONTROLS
OPERATING SEQUENCE
Heating — When the thermostat calls for heating, terminal ‘‘W’’
is energized, starting the induced-draft motor. When the halleffect sensor on the induced-draft motor senses that it has
reached the required speed, the burner ignition sequence begins. The indoor (evaporator) fan motor (IFM) is energized
45 seconds after flame is established. When the thermostat is
satisfied and ‘‘W’’ is deenergized, the IFM stops after a
45-second time-off delay.
Cooling — When the system thermostat calls for cooling, 24 V
is supplied to the ‘‘Y’’ and ‘‘G’’ terminals of the thermostat. This
completes the circuit to the contactor coil (C) and indoor (evaporator) fan relay (IFR). The normally open contacts of C close
and complete the circuit through compressor motor (COMP) to
outdoor (condenser) fan motor (OFM). Both motors start instantly.The set of normally open contacts of IFR close and complete the circuit through IFM. The IFM starts instantly.
On the loss of the thermostat call for cooling, 24 v is removed
from both the ‘‘Y’’ and ‘‘G’’ terminals (provided the fan switch is
in the ‘‘AUTO’’ position) deenergizing the compressor contactor
and opening the contacts supplying power to compressor/OFM.
After a 30-second delay, the IFM shuts off. If the thermostat
fan selector switch in is the ‘‘ON’’ position, the IFM will run
continuously.
NOTE: On units with a Time GuardT II device: once the com-
pressor has started and then stopped, it cannot be restarted
again until 5 minutes have elapsed.
