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 computerdesigned for optimum heat transfer and cooling efficiency. Condenser coil is fabricated of copper tube and aluminum fins and
is located inside the unit for protection against damage and for
long life and reliable operation. The condenser coil is internally
mounted and protected by a composite grille.
Copper fin coils for condenser coil are also available by special
order. These coils are recommended in applications where aluminum fins are likely to be damaged due to corrosion. Copper
fin coils are ideal for seacoast applications.
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, needs cleaning.
WEATHERIZED CABINETS are constructed of heavy-duty,
phosphated, zinc-coated prepainted steel capable of withstanding 500 hours in salt spray. Interior surfaces of the evaporator
compartment are insulated with foil-faced fiberglass to help
keep the conditioned air from being affected by the outdoor ambient temperature and provide improved air quality.Conforms to
American Society of Heating, Refrigeration and Air Conditioning
Engineers (ASHRAE) No. 62P. Sloped condensate pan permits
an external drain.
LOW SOUND RATINGS ensure a quiet indoor and outdoor environment with sound ratings as low as 7.4 bels.
EASY TO SERVICE CABINETS provide easy accessibility to
serviceable components during maintenance and installation.
Rounded corners are an important safety feature, and a highquality finish ensures an attractive appearance.
LOW AND HIGH VOLTAGE ELECTRICAL ENTRIES allow low
and high voltage to be brought in either through the duct panel
or rear flue panel.
INTEGRATED GAS CONTROL BOARD provides safe and efficient control of heating and simplifies troubleshooting through
its built-in diagnostic function.
OPTIONAL BASE RAILS provide holes for rigging and handling as well as an elevated mounting frame that provides structural support for horizontal installations.
DOWNFLOW OPTIONS is converted for downflow at factory for
easy vertical ductwork connections.

mounting frame.
SUGGESTED USE:
• Rigging holes to provide greater ease in handling. Frame to
provide elevation and structural support for horizontal
applications.
FIELD-INSTALLED ACCESSORY DESCRIPTION AND USAGE
Downflow Option — Unit is shipped from factory configured for
downflow application. Unit is equipped with base rail.
SUGGESTED USE:
• To provide easy vertical ductwork connections.
Flat Roof Curb — Consists of galvanized steel support frame in
8-, 11-, and 14-in. high designs. Provides wood nailer to attach
roof counter flashing. Insulated basepans in curbs are provided
to prevent condensation. Ductwork attaches to rails provided in
the roof curb. A gasket is provided to form an airtight and watertight seal between unit and curb. The roof curb design meets
the standards of the NRCA (National Roofing Contractors’
Association).
SUGGESTED USE:
• Slab-mounted applications when elevation of the unit above
the slab is necessary.
• Rooftop application for downflow discharge.
• Curbs are preassembled and are available for flat or pitched
roofs.
Pitched Roof Curb — Provided in ratios of 1, 2, 3, 4, 5, and 6
to 12 for use on pitched roof applications.
SUGGESTED USE:
• For when a roof curb is needed on a pitched roof.
Modulating Economizer — Economizer is available for downflow or horizontal applications, and is designed for easy installation. Economizer reduces energy costs and extends
equipment life by allowing the use of outdoor air to supply ‘‘free’’
cooling when conditions are favorable.
Constant ventilation is recommended for light commercial applications when the conditioned space is occupied.
The economizer is shipped complete with a damper motor and
linkage, enthalpy control, low-voltage wiring harness, and a
rainhood. Adequate wire lengths are provided (additional fieldsupplied wires are not required). Horizontal economizers are
also furnished with a 2-in. disposable air filter and gasket
material.
Modulating economizer package consists of low-leakage dampers with controls. The economizer will allow a fixed percentage
of outdoor ventilation air into the unit whenever the evaporator
fan is running.
SUGGESTED USE:
• Allows outdoor air to be used for ‘‘free’’ cooling whenever the
outdoor air is below the enthalpy control setting.
• To reduce energy usage. Use whenever the hours of operation at temperatures below 40 F are significant.
Two-Position Damper — In the two-position dampers, the enthalpy control detects when outdoor air is suitable for ‘‘free’’
cooling by measuring the outdoor-air dry bulb temperature and
humidity. Whenever the outdoor-air quality is acceptable for
‘‘free’’ cooling, the outdoor-air damper opens fully and the
return-air damper closes, allowing outdoor air to enter the
building.
SUGGESTED USE:
• Allows use of outdoor air to cool building without using compressor. Damper closes when evaporator fan is off to prevent
cold backdraft, and wasted energy.

SELECTION PROCEDURE
I DETERMINE COOLING AND HEATING REQUIRE-
MENTS AT DESIGN CONDITIONS:
Given:
Required Cooling Capacity (TC) ..........34,000 Btuh
Sensible Heat Capacity (SHC) ...........24,000 Btuh
Required Heating Capacity ..............60,000 Btuh
Condenser Entering-Air Temperature ............95F
Indoor-Air Temperature ...........80Fedb, 67 F ewb
Evaporator-Air Quantity ...................1200 cfm
External Static Pressure .................0.20 in. wg
Electrical Characteristics (V-Ph-Hz) ..........208-1-60
II SELECT UNIT BASED ON REQUIRED COOLING
CAPACITY.
Enter Net Cooling Capacities table at condenser entering
temperature of 95 F. Unit 588A036 at 1200 cfm and 67 F
ewb (entering wet bulb) will provide a total capacity of
36,000 Btuh and an SHC of 26,200 Btuh. Calculate SHC
correction, if required, using Note 4 under Net Cooling Capacities tables.
III SELECT HEATING CAPACITY OF UNIT TO PROVIDE
DESIGN CONDITION REQUIREMENT.
In the Heating Capacities and Efficiencies table on page 4,
note that unit 588A036080 will provide 64,800 Btuh with an
input of 80,000 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 given, the Wet Coil
Pressure Drop table, and the Filter Pressure Drop table on
page 19, find at 1200 cfm:
External static pressure 0.20 in. wg
Wet Coil 0.088 in. wg
Filter 0.13 in. wg
Total static pressure 0.42 in. wg (rounded)
Enter the table for Dry Coil Air Delivery — Horizontal Discharge for 230 and 460 V on page 17. For 208 v operation,
deduct 10% from value given. The fan will deliver 1233 cfm
at 0.4 external static pressure (1370 x 0.9) at high speed
and 852 cfm at 0.5 external static pressure (946 x 0.9) at
low speed. The fan speed should be set at high to satisfy
job requirements.
V SELECT UNIT THAT CORRESPONDS TO POWER
SOURCE AVAILABLE.
The Electrical Data table on page 20 shows that the unit
is designed to operate at 208-1-60.

OPERATING SEQUENCE
HEATING
On a call for heating, terminal ‘‘W’’ of the thermostat is energized, starting the induced-draft motor. When the hall-effect
sensor on the induced-draft motor senses that it has reached
the required speed, the burner sequence begins. This sequence
is performed by the integrated gas control board (IGC). The
indoor-fan motor is energized 45 seconds after flame is established. When the thermostat is satisfied and ‘‘W’’ is deenergized, the indoor-fan motor stops after a 45-second time-off
delay.
COOLING
With the room thermostat SYSTEM switch in the COOL position
and the FAN switch in theAUTO. position, the cooling sequence
of operation is as follows:
When the room temperature rises to a point that is slightly
above the cooling control setting of the thermostat, the thermostat completes the circuit between thermostat terminal R to terminals Y and G. These completed circuits through the
thermostat connect contactor coil (C) (through unit wire Y) and
blower relay coil (BR) (through unit wire G) across the 24-v secondary of transformer (TRAN).
The normally-open contacts of energized contactor (C) close
and complete the circuit through compressor motor (COMP) to
condenser (outdoor) fan motor (OFM). Both motors start
instantly.
The set of normally-open contacts of energized relay BR close
and complete the circuit through evaporator blower (indoor) fan
motor (IFM). The blower motor starts instantly.
NOTE: Once the compressor has started and then has stopped,
it should not be started again until 5 minutes have elapsed.
The cooling cycle remains ‘‘on’’ until the room temperature
drops to point that is slightly below the cooling control setting of
the room thermostat. At this point, the thermostat ‘‘breaks’’ the
circuit between thermostat terminal R to terminals Y and G.
These open circuits deenergize contactor coil C and relay coil
BR. The condenser and compressor motors stop. After a
30-second delay, the blower motor stops. The unit is in a
‘‘standby’’ condition, waiting for the next ‘‘call for cooling’’ from
the room thermostat.
