SAFETY CONSIDERATIONS
Installation and servicing of air-conditioning equipment can
be hazardous due to system pressure and electrical compo-
nents. Only trained and qualified service personnel should
install, repair, or service air-conditioning equipment.
Untrained personnel can perform basic maintenance func-
tions of cleaning coils and filters and replacing filters. All
other operations should be performed by trained service per-
sonnel. When working on air-conditioning equipment,
observe precautions in the literature, tags and labels
attached to the unit, and other safety precautions that apply.
Follow all safety codes. Wear safety glasses and work gloves.
Use quenching cloth for unbrazing operations. Have fire
extinguishers available for all brazing operations.
INSTALLATION
Unit is shipped in the vertical duct configuration. To convert to
horizontal configuration, remove screws from side duct open-
ing covers and remove covers. Using the same screws, install
covers on vertical duct openings with the insulation-side down.
Seals around duct openings must be tight. See Fig. 2.
Confirm before installation of unit that voltage, amperage
and circuit protection requirements listed on unit data plate
agree with power supply provided.
I. STEP 1 — PROVIDE UNIT SUPPORT
A. Roof Curb
Assemble and install accessory roof curb in accordance with
instructions shipped with curb. See Fig. 3. Install insulation,
cant strips, roofing felt, and counter flashing as shown. Duct-
work must be attached to curb, not to the unit. The accessory
thru-the-bottom power and gas connection package must be
installed before the unit is set on the roof curb. If field-
installed (thru-the-roof curb) gas connections are desired, use
factory-supplied 3/4-in. pipe coupling and gas plate assembly
to mount the thru-the-roof curb connection to the roof curb.
Gas connections and power connections to the unit must be
field installed after the unit is installed on the roof curb.
If electric and control wiring is to be routed through the
basepan, attach the accessory thru-the-bottom service con-
nections to the basepan in accordance with the accessory
installation instructions.
IMPORTANT: The gasketing of the unit to the roof curb is
critical for a watertight seal. Install gasket supplied with the
roof curb as shown in Fig. 3. Improperly applied gasket can
result in air leaks and poor unit performance.
Curb should be level. Unit leveling tolerances are shown in
Fig. 4. This is necessary for unit drain to function properly.
Refer to Accessory Roof Curb Installation Instructions for
additional information as required.
WARNING: Disconnect gas piping from unit when
leak testing at pressure greater than 1/2psig. Pres-
sures greater than 1/2psig will cause gas valve damage
resulting in hazardous condition. If gas valve is sub-
jected to pressure greater than 1/2psig, it must be
replaced before use. When pressure testing field-
supplied gas piping at pressures of 1/2psig or less, a
unit connected to such piping must be isolated by man-
ually closing the gas valve.
WARNING: Before performing service or mainte-
nance operations on unit, turn off main power switch
to unit and install a lockout tag. Electrical shock could
cause personal injury.
CAUTION: Ensure voltage listed on unit data plate
agrees with electrical supply provided for the unit.

B. Slab Mount (Horizontal Units Only)
Provide a level concrete slab that extends a minimum of 6 in.
beyond unit cabinet. Install a gravel apron in front of condenser
coil air inlet to prevent grass and foliage from obstructing airflow.
NOTE: Horizontal units may be installed on a roof curb if
required.
C. Alternate Unit Support
A non-combustible sleeper rail can be used in the unit curb
support area. If sleeper rails cannot be used, support the
long sides of the unit with a minimum of 3 equally spaced
4-in. x 4-in. pads on each side.
II. STEP 2 — FIELD FABRICATE DUCTWORK
Secure all ducts to roof curb and building structure on verti-
cal ducted units. Do not connect ductwork to unit. For hori-
zontal applications, field-supplied flanges should be attached
to horizontal duct openings and all ductwork should be
secured to the flanges. Insulate and weatherproof all exter-
nal ductwork, joints, and roof openings with counter flashing
and mastic in accordance with applicable codes.
Ducts passing through an unconditioned space must be insu-
lated and covered with a vapor barrier.
If a plenum return is used on a vertical unit, the return
should be ducted through the roof deck to comply with appli-
cable fire codes.
A minimum clearance is not required around ductwork. Cab-
inet return air static shall not exceed –.20 in. wg with
economizer or –.45 in. wg without economizer.
These units are designed for a minimum continuous heating
return-air temperature of 50 F (dry bulb), or an intermittent
operation down to 45 F (dry bulb), such as when used with a
night set-back thermostat.
To operate at lower return-air temperatures, a field-supplied
outdoor air temperature control must be used to initiate both
stages of heat when the temperature is below 45 F. Indoor
comfort may be compromised when these lower air tempera-
tures are used with insufficient heating temperature rise.
III. STEP 3 — INSTALL EXTERNAL TRAP FOR CONDEN-
SATE DRAIN
The unit’s 3/4-in. condensate drain connections are located on
the bottom and side of the unit. Unit discharge connections do
not determine the use of drain connections; either drain con-
nection can be used with vertical or horizontal applications.
When using the standard side drain connection, make sure
the plug (Red) in the alternate bottom connection is tight
before installing the unit.
To use the bottom drain connection for a roof curb installation,
relocate the factory-installed plug (Red) from the bottom con-
nection to the side connection. The center drain plug looks like
a star connection, however it can be removed with a 1/2-in.
socket drive. See Fig. 5A. The piping for the condensate drain
and external trap can be completed after the unit is in place.
All units must have an external trap for condensate drainage.
Install a trap at least 4-in. deep and protect against freeze-up.
If drain line is installed downstream from the external trap,
pitch the line away from the unit at 1 in. per 10 ft of run. Do
not use a pipe size smaller than the unit connection (3/4in.).
See Fig. 5B.
IV. STEP 4 — RIG AND PLACE UNIT
Inspect unit for transportation damage. File any claim with
transportation agency. Keep unit upright and do not drop.
Spreader bars are not required if top crating is left on unit.
Rollers may be used to move unit across a roof. Level by
using unit frame as a reference. See Table 1 and Fig. 6 for
additional information.
Lifting holes are provided in base rails as shown in Fig. 1A
and 1B. Refer to rigging instructions on unit.
A. Positioning
Maintain clearance around and above unit to provide mini-
mum distance from combustible materials, proper airflow,
and service access. See Fig. 1A and 1B. A properly positioned
unit will have the following clearances between unit and roof
curb: 1/4-in. clearance between roof curb and base rails on
each side and duct end of unit; 1/4-in. clearance between roof
curb and condenser coil end of unit. (See Fig. 3, section C-C.)
CAUTION: All panels must be in place when rigging.

Do not install unit in an indoor location. Do not locate unit
air inlets near exhaust vents or other sources of contami-
nated air.
Be sure that unit is installed such that snow will not block
the combustion intake or flue outlet.
Unit may be installed directly on wood flooring or on Class
A, B, or C roof-covering material when roof curb is used.
Although unit is weatherproof, guard against water from
higher level runoff and overhangs.
Flue vent discharge must have a minimum horizontal clear-
ance of 4 ft from electric and gas meters, gas regulators, and
gas relief equipment.
Minimum distance between unit and other electrically live
parts is 48 inches.
Flue gas can deteriorate building materials. Orient unit such
that flue gas will not affect building materials.
Adequate combustion-air space must be provided for
proper operation of this equipment. Be sure that installation
complies with all local codes and Section 5.3, Air for Combus-
tion and Ventilation, NFGC (National Fuel Gas Code), and
ANSI (American National Standards Institute) Z223.1, and
NFPA (National Fire Protection Association) 54 TIA-54-84-1.
In Canada, installation must be in accordance with the
CAN1-B149 installation codes for gas burning appliances.
After unit is in position, remove rigging skids and shipping
materials.
V. STEP 5 — INSTALL FLUE HOOD
Flue hood is shipped screwed to the basepan beside the
burner compartment access panel. Remove from shipping
location and using screws provided, install flue hood and
screen in location shown in Fig. 7.
VI. STEP 6 — INSTALL GAS PIPING
Unit is equipped for use with type of gas shown on name-
plate. Refer to local building codes, or in the absence of local
codes, to ANSI Z223.1 entitled National Fuel Gas Code. In
Canada, installation must be in accordance with the
CAN1.B149.1 and CAN1.B149.2 installation codes for gas
burning appliances.
For natural gas applications, gas pressure at unit gas con-
nection must not be less than 4 in. wg or greater than
13.0 in. wg while unit is operating. On 580F048,060,072 high
heat units, the gas pressure at unit gas connection must not
be less than 5 in. wg or greater than 13 in. wg while the unit
is operating. For propane applications, the gas pressure
must not be less than 5 in. wg or greater than 13 in. wg at
the unit connection.
Size gas supply piping for 0.5 in. wg maximum pressure
drop. Do not use supply pipe smaller than unit gas connec-
tion. Support gas piping as shown in the table in Fig. 8. For
example, a 3/4-in. gas pipe must have one field-fabricated
support beam every 8 ft. Therefore, an 18-ft long gas pipe
would have a minimum of 2 support beams, a 48-ft long pipe
would have a minimum of 6 support beams.
See Fig. 8 for typical pipe guide and locations of external
manual main shutoff valve.
CAUTION: When connecting the gas line to the
unit gas valve, the installer MUST use a backup
wrench to prevent valve damage.

VII. STEP 7 — MAKE ELECTRICAL CONNECTIONS
A. Field Power Supply
All units except 208/230-v units are factory wired for the
voltage shown on the nameplate. If the 208/230-v unit is to
be connected to a 208-v power supply, the transformer must
be rewired by moving the black wire with the 1/4-in. female
space connector from the 230-volt connection and moving to
the 208-volt 1/4-in. male terminal on the primary side of the
transformer.
Refer to unit label diagram for additional information.
Pigtails are provided for field wire connections. Use factory-
supplied splices or UL (Underwriters’ Laboratories)
approved copper/aluminum connector.
When installing units, provide a disconnect per the NEC.
All field wiring must comply with NEC and local require-
ments.
Install field wiring as follows:
1. Install conduit through side panel openings. Install
conduit between disconnect and control box.
2. Install power lines to terminal connections as shown
in Fig. 9.
Voltage to compressor terminals during operation must be
within voltage range indicated on unit nameplate (see
Tables 2A and 2B). On 3-phase units, voltages between
phases must be balanced within 2% and the current within
10%. Use the formula shown in the legend for Tables 2A and
2B, Note 2 to determine the percent of voltage imbalance.
Operation on improper line voltage or excessive phase imbal-
ance constitutes abuse and may cause damage to electrical
components. Such operation would invalidate any applicable
Bryant warranty.
B. Field Control Wiring
Install a Bryant-approved accessory thermostat assembly
according to installation instructions included with the
accessory. Locate thermostat assembly on a solid wall in the
conditioned space to sense average temperature in accor-
dance with thermostat installation instructions. Connect
thermostat wires to terminal board.
Route thermostat cable or equivalent single leads of colored
wire from subbase terminals through connector on unit to
low-voltage connections (shown in Fig. 10).
NOTE: For wire runs up 50 ft, use no. 18 AWG (American
Wire Gage) insulated wire (35 C minimum). For 50 to 75 ft,
use no. 16 AWG insulated wire (35 C minimum). For over
75 ft, use no. 14 AWG insulated wire (35 C minimum). All
wire larger than no. 18 AWG cannot be directly connected to
the thermostat and will require a junction box and splice at
the thermostat.
Pass the control wires through the hole provided in the cor-
ner post; then feed wires through the raceway built into the
corner post to the 24-v barrier located on the left side of the
control box. See Fig. 11. The raceway provides the UL
required clearance between high-voltage and low-voltage
wiring.
C. Heat Anticipator Settings
Set heat anticipator settings at .14 amp for the first stage
and .14 amp for second-stage heating, when available.
WARNING: Unit cabinet must have an uninter-
rupted, unbroken electrical ground to minimize the possi-
bility of personal injury if an electrical fault should occur.
This ground may consist of electrical wire connected to
unit ground lug in control compartment, or conduit
approved for electrical ground when installed in accor-
dance with NEC (National Electrical Code), ANSI/NFPA,
latest edition, and local electrical codes. Do not use gas
piping as an electrical ground. Failure to follow this
warning could result in the installer being liable for per-
sonal injury of others.BLOWER

*Used to determine minimum disconnect per NEC.
†Fuse or HACR circuit breaker.
NOTES:
1. In compliance with NEC requirements for multimotor and combination load equipment (refer
to NEC Articles 430 and 440), the overcurrent protective device for the unit shall be fuse or
HACR breaker. Canadian units may be fuse or circuit breaker.
2. Unbalanced 3-Phase Supply Voltage
Never operate a motor where a phase imbalance in supply voltage is greater than 2%. Use
the following formula to determine the percent of voltage imbalance.
%Voltage Imbalance
Example: Supply voltage is 460-3-60.
AB =452 v
BC =464 v
AC =455 v
=457
Determine maximum deviation from average voltage.
(AB)457–452=5v
(BC) 464 – 457 =7v
(AC)457–455=2v
Maximum deviation is 7 v.
Determine percent of voltage imbalance.
=1.53%
This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%.
IMPORTANT: If the supply voltage phase imbalance is more than 2%, contact your local electric
utility company immediately.
3. For units with power exhaust: If a single power source is to be used, size wire to include
power exhaust MCA and MOCP. Check MCA and MOCP when power exhaust is powered
through the unit (must be in accordance with NEC and/or local codes). Determine the new
MCA including the power exhaust using the following formula:
MCA New =MCA unit only +MCA of Power Exhaust
For example, using a 580F060 unit with MCA =28.9 and MOCP =35, with
CRPWREXH030A00 power exhaust.
MCA New =28.9 amps +1.6 amps =30.5 amps
If the new MCA does not exceed the published MOCP, then MOCP would not change. The
MOCP in this example is 35 amps, the MCA New is below 35, therefore the MOCP is
acceptable. If “MCA New” is larger than the published MOCP, raise the MOCP to the next
larger size. For separate power, the MOCP for the power exhaust will be 15 amps per NEC.

C. EconoMi$er+ Control Mode
Determine the EconoMi$er+ control mode before installing
sensors and accessories. Different sensors are required for
different control modes, and a number of accessories are
available. Refer to Tables 3 and 4.
Outdoor Dry Bulb Changeover
The standard control mode for the EconoMi$er+ is Outdoor
Dry Bulb Changeover. The outdoor air and supply air tem-
perature sensors are also included as standard.
EconoMi$er+ control is based on the outdoor temperature
relative to a set point in the software. If the outdoor air
temperature is above the set point then the EconoMi$er
should be in minimum position. If the outdoor air tempera-
ture is below the set point, the position should be controlled
to maintain the leaving air temperature set point. The set
point range is 45 to 70 F.
Differential Dry Bulb Changeover
The control supports differential dry bulb changeover con-
trol. This requires an accessory return air temperature
sensor CRTEMPSN001A00 installed in the return air-
stream. Refer to the Start-up section for details on how to
configure and enable the control mode. The user can check
the operation of the sensor using the Read function.
Outdoor Air Enthalpy Changeover
The control supports outside air enthalpy changeover con-
trol. This mode requires a factory-supplied outdoor air tem-
perature sensor (OAT) and an accessory outdoor air
humidity sensor (ORH) (part no. CRHUMDSN001B00).
Refer to the Start-Up section for details on how to configure
and enable the control mode. The user can check the opera-
tion of the sensors using the Read function.
Differential Enthalpy Changeover
The control supports differential enthalpy changeover con-
trol. This requires the factory-supplied outside air tempera-
ture sensor, an accessory outdoor air humidity sensor, an
accessory return air temperature sensor, and an accessory
indoor air humidity sensor. Refer to the Start-Up section for
details on how to configure and enable the control mode. The
user can check the operation of the sensors using the Read
function.
D. Damper Movement
When the EconoMi$er+ board receives initial power, it will
take the damper up to 21/2minutes before it begins to posi-
tion itself. After the initial positioning, subsequent changes
to damper position will take up to 30 seconds to initiate.
Damper movement from full open to full closed (or vice
versa) takes 21/2minutes.
If the damper is in the process of changing positions (for
example it is trying to open to 100%) and the fan signal is
turned off, the damper will continue to its 100% open posi-
tion before closing.
NOTE: Occupied minimum position can not be set lower than
+1% higher than the value of IAQ minimum economizer
position. Refer to the setup examples on page 42.
E. EconoMi$er+ Controller Wiring
The EconoMi$er+ is supplied from the factory with a supply
air temperature sensor and an outside air temperature sen-
sor. This allows for operation of the EconoMi$er+ with out-
side air dry bulb changeover control. Additional accessories
can be added to allow for different types of change over con-
trol and operation of the EconoMi$er+ and unit.
F. Thermostats
The EconoMi$er+ control works with conventional thermo-
stats that have a Y1 (cool stage 1), Y2 (cool stage 2), W1
(heat stage 1), W2 (heat stage 2), and G (fan). The
EconoMi$er+ control does not support sensor thermostats
like the T56 and T57. Connections are made at the thermo-
stat terminal connection board located in the main control
box.

Table 4 — EconoMi$er+ Field-Installed Accessories
*5-pin sensor wiring plug accessory (P/N CRE+PLUG001A00) is
required to install IAQ sensor.
G. Outdoor Air Temperature (OAT)Sensor (Provided)
The outdoor air temperature sensor is a 10K thermistor used
to measure the outdoor-air temperature. The sensor controls
EconoMi$er+ changeover and compressor lockout. The sen-
sor is factory-installed on the EconoMi$er+ in the outdoor
airstream. The operating range of temperature measure-
ment is 0° to 158 F. See Tables 5 and 6 for thermistor resis-
tance and resolution values.
The temperature sensor looks like an eyelet terminal with
wires running to it. The sensor is located in the “crimp end”
and is sealed from moisture.
The user can read the value of the sensor using the Read
mode, described in the Start-Up section.
H. Supply Air Temperature (SAT)Sensor (Provided)
The supply air temperature sensor is a 10K thermistor
located at the inlet to the indoor fan. This sensor must be
field installed. The operating range of temperature measure-
ment is 0° to 158 F. See Tables 5 and 6 for thermistor resis-
tance and resolution values.
The temperature sensor looks like an eyelet terminal with
wires running to it. The sensor is located in the “crimp end”
and is sealed from moisture.
The user can read the value of the sensor using the Read
mode, described in the EconoMi$er+ Controller section.
I. Indoor Air Quality (IAQ) Sensor
Any indoor air quality or CO2sensor that provides a 4 to
20 mA output can be used as the IAQ sensor. The controller
will modulate the outdoor-air damper to provide ventilation
based on the sensor output and the IAQ setting of the con-
troller. The CO2sensor will modulate the outdoor-air damper
from the minimum position (IAQ minimum damper position
set point) to the maximum position (occupied minimum
damper position). When there is no CO2call, the damper will
go to the unoccupied minimum position. When there is a CO2
call, the damper will be between the IAQ minimum econo-
mizer set point position and the occupied minimum damper
position.
Mount the sensor according to manufacturer specifications.
In order to wire this sensor, an accessory 5-pin plug (part
number CRE+PLUG001A00) is required. See Fig. 22.
The IAQ sensor is wired to the ground and IAQ wires in the
harness. The accessory 5-pin wiring plug is connected to pins
13-17 of J3 on the EconoMi$er+ controller. Push the plug
down onto the pins of the EconoMi$er+ controller to install.
Pins 13 and 14 are used for the IAQ sensor. Pins 15-17 are
used for the field-installed remote potentiometer. Connect
the IAQ sensor to the BRN and WHT wires of the accessory
5-pin plug.
NOTE: Pin numbers are not shown on the controller. They
are provided only as reference for the installer. On the
EconoMi$er+ board, they numbered 1-17 from left to right,
but only the 1 and the 17 are printed on the board.
Sensor wiring should be extended with wire and wire nuts
and routed to the IAQ sensor location. Adjust the IAQ set-
ting at the controller to correspond to the IAQ voltage output
of the sensor at the user-determined set point. See Fig. 26.
Power the sensor with a field-supplied transformer.
J. Return Air Temperature (RAT)Sensor
The EconoMi$er+ controller will accept input from the
accessory 10K return air temperature sensor
(CRTEMPSN001A00) in addition to the outdoor air tempera-
ture sensor shipped with the EconoMi$er+. By using both
sensors, the outdoor air and the return air temperatures are
compared (differential dry bulb) for optimal energy savings.
See Tables 5 and 6 for thermistor resistance and resolution
values.
The temperature sensor looks like an eyelet terminal with
wires running to it. The sensor is located in the “crimp end”
and is sealed from moisture.

The user can read the value of the sensor using the Read
mode, described in the EconoMi$er+ Controller section.
Mount the return air temperature sensor on the
EconoMi$er+, through pre-punched holes. See Fig. 27.
The return air temperature (RAT) sensor is provided with a
2-wire, 42-in. long wiring harness with a 2-pin connector. The
plug is installed on pins 5 and 6 on J3 of the EconoMi$er+
controller. The pins are labeled with a ground symbol and
RAT on the EconoMi$er+ controller. See Fig. 22. The red wire
of the harness is connected to pin 5 (ground). The black wire
of the harness is connected to pin 6 (RAT). The wiring har-
ness should be routed from the EconoMi$er+ controller to the
sensor. The controller compares the temperatures of the two
airstreams, chooses the best one, and modulates the
EconoMi$er+ actuator accordingly.
This 10K thermistor is used to measure the return air
temperature vs. resistance curve, per Table 5. The range of
temperature measurement is between 0° and 158 F. See
Table 6 for resolution.
K. Outdoor Air Humidity Sensor
The EconoMi$er+ controller accepts input from the accessory
outdoor air humidity sensor in addition to the outdoor air
temperature sensor shipped with the EconoMi$er+. By using
both sensors, the total enthalpy of the outside air is
calculated.
Mount the outdoor-air humidity sensor in to the
EconoMi$er+, through the pre-punched holes. See Fig. 28.
The outdoor-air humidity sensor is provided with a 2-wire,
42-in. wiring harness with a 2-pin connector. The plug is
installed on pins 11 and 12 on J3 of the EconoMi$er+ con-
troller. The pins are labeled ORH and VREF on the
EconoMi$er+ controller. See Fig. 22. The orange wire of the
harness is connected to pin 11 (ORH). The blue wire of the
harness is connected to pin 12 (VREF). The wiring harness
should be routed from the EconoMi$er+ controller to the sen-
sor location.
The outdoor enthalpy changeover curve is set at the
EconoMi$er+ controller. The factory default is curve “A.” See
Fig. 29. See Fig. 30 for Sensor Curve vs. Humidity.
