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.
582A units with an “N” in the thirteenth position of model number are dedicated Low NOx units designed for California installations. These models meet the California maximum oxides of
nitrogen (NOx) emissions requirement of 40 nanograms/joule or
less as shipped from the factory and MUST be installed in California Air Quality Management Districts where a Low NOx rule
exists.
Single-Packaged Rooftop Units with
• Direct Spark Ignition
• Low Sound Levels
• Up to 81% AFUE
• 10 SEER
FEATURES/BENEFITS
One-piece heating and cooling units with low sound levels, 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.
The 582A 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 unit base 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 the use
of two included duct covers.
EFFICIENT OPERATION
High-Efficiency Design offers SEER (Seasonal Energy Efficiency Ratios) of 10.0 and AFUE (Annual Fuel Utilization Efficiency) ratings as high as 81.1%.
DURABLE, DEPENDABLE COMPONENTS
Compressors are designed for high efficiency. Each compressor 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 582A 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. Motormaster® II low ambient option is available as a field-installed accessory.
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.
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 and are ideal for seacoast applications.
Low Sound Ratings ensure a quiet indoor and outdoor environment with sound ratings as low as 75dB. (See ARI capacity
charts for individual values.)
Form No. PDS 582A.18.4
FEATURES/BENEFITS (cont)
Easy-to-Service Cabinets provide easy single-panel accessibility to serviceable components during maintenance and
installation. The unit base with integrated drain 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 unit base 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 unit is easily converted for downflow in
the field to allow vertical ductwork connections. The unit base
utilizes knockout style seals on the bottom openings to ensure a
positive seal in the horizontal airflow mode.
Integrated Gas Control Board provides safe and efficient control of heating and simplifies troubleshooting with 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 [ASHRAE] No. 62P.) The
sloped drain minimizes standing water in the drain. An external
drain is provided.

SELECTION PROCEDURE (with example)
I
DETERMINE COOLING AND HEATING REQUIREMENTS
AT DESIGN CONDITIONS:
Given:
Required Cooling Capacity (TC) ....................34,000 Btuh
Sensible Heat Capacity (SHC) ........................25,000 Btuh
Required Heating Capacity .............................60,000 Btuh
Condenser Entering Air Temperature .........................95°F
Indoor-Air Temperature .......................80°F edb 67°F ewb
Evaporator Air Quantity ....................................1200 CFM
External Static Pressure ......................................0.4 in. wg
Electrical Characteristics ......................................230-1-60
II
SELECT UNIT BASED ON REQUIRED COOLING
CAPACITY.
Enter Net Cooling Capacities table at outdoor entering
temperature of 95°F. Unit 582A036 at 1200 cfm and 67°F
ewb (entering wet bulb) will provide a total capacity of
34,400 Btuh and a SHC of 25,400 Btuh.
III
IV
DETERMINE FAN SPEED AND POWER REQUIREMENTS
AT DESIGN CONDITIONS.
Before entering the air delivery tables, calculate the total
static pressure required. From the given example, the Wet
Coil Pressure Drop Table, and the Filter Pressure Drop table
on page 15, find at 1200 cfm:
External Static Pressure
0.40 in. wg
Wet Coil
0.10 in. wg
Filter/Economizer
0.13 in. wg
Total Static Pressure
0.63 in. wg
Enter the table for Dry Coil Air Delivery — Horizontal and
Downflow Discharge for 230 V and 460 V on page 14. The
fan will deliver 1333 CFM at 0.63 SP (static pressure) at high
speed and use 719 watts. The fan speed should be set at
high.
V
SELECT HEATING CAPACITY OF UNIT TO PROVIDE
DESIGN CONDITION REQUIREMENT.
In the Heating Capacities and Efficiencies table on page 3,
note that the unit 582A036090 will provide 71,000 Btuh
with an input of 90,000 Btuh.

BF — Bypass Factor
Ewb — Entering Wet-Bulb
kW — Total Unit Power Input
SHC — Sensible Heat Capacity (1000 Btuh)
TC — Total Capacity (1000 Btuh) (net)
NOTES:
1. Ratings are net; they account for the effects of the evaporatorfan motor power and heat.
2. Direct interpolation is permissible. Do not extrapolate.
3. The following formulas may be used:
tldb = .t edb – sensible capacity (Btuh)
1.10 x cfm
tlwb = Wet-bulb temperature corresponding to enthalpy
of air leaving evaporator coil (hlwb)
hlwb = hewb –
Where: hewb
=
total capacity (Btuh)
4.5 x cfm
Enthalpy of air entering evaporator coil
4. The SHC is based on 80F edb temperature of air entering evaporator coil.
Below 80F edb, subtract (Corr Factor x CFM) from SHC.
Above 80F edb, add (corr factor x CFM) to SHC.
Correction Factor = 1.10 x (1 – BF) x (edb – 80).

APPLICATION DATA
CONDENSATE TRAP — A 2-in. condensate trap must be field
supplied.
MINIMUM COOLING AIRFLOW — Minimum cooling airflow is
350 cfm per ton.
DUCTWORK — Secure downflow discharge ductwork to roof
curb. For horizontal discharge applications, attach ductwork to
unit with flanges.
MINIMUM COOLING AMBIENT OPERATING TEMPERATURE — For all standard units the minimum ambient operating
temperature is 40°F. With accessory low ambient temperature
kit, units can operate at temperatures down to 0°F.
TO CONVERT A UNIT TO DOWNFLOW DISCHARGE — Units
are equipped with factory-installed inserts in the downflow
openings. Removal of the inserts is similar to removing an
electrical knock-out. Use the duct cover supplied to seal the
horizontal discharge openings in the unit. Units installed
horizontal discharge orientation do not require duct covers.
MINIMUM TEMPERATURE — Air entering the heat exchanger
in heating mode must be a minimum of 50°F continuous and/or
45°F intermittent.
MAXIMUM COOLING AIRFLOW — To minimize the possibility
of condensate blow-off from the evaporator, airflow through the
units should not exceed 450 cfm per ton.

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) blower relay (BR). The normally open contacts of energized 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 energized BR 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 is in the “ON” position, the IFM will run
continuously.
NOTE: On units with a Time Guard® II device: Once the compressor has started and then stopped, it cannot be restarted
again until five minutes have elapsed.
