SAFETY CONSIDERATIONS
Installation and servicing of air-conditioning equipment can be hazardous due to system pressure and electrical compo­nents. Only trained and qualified service personnel should install, repair, or servic e air-conditioning equipment.
Untrained personnel can perform basic maintenance func­tions of cleaning coils and filters and replacing filters. All other operations should be performed by trained service per­sonnel. When working on air-conditioning equipment, observe precautions in the literature, tags and labels attached to the unit, and other safety precautions that may 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.
CAUTION: Ensure voltage listed on unit data plate
agrees with electrical supply provided for the unit.
WARNING: Disconnect gas piping from unit when leak testing at pressure greater than 1/2 psig. Pres­sures greater tha n resulting in hazardous condition. If gas valve is ever subjected to pressure greater than replaced before use. When pressure testing field­supplied gas piping at pressures of unit connected to such piping must be isolated by man­ually closing the gas valve(s).
WARNING: Before performing service or mainte­nance operations on unit, turn off main power switch to unit and install lockout tag. Electrical shock could cause personal injury.
Unit is shipped in the vertical discharge configuration. To convert to horizontal configuration, remove screws from side duct opening 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 access ory roof curb in accorda nce with instructions shipped with curb. See Fig. 3. Install insulation, cant strips, roofi ng fe lt, and counter flashing as shown. Duct- work must be attached to curb. If gas or electr ical co nnec tion s are to be routed through the curb, attach the access ory thru­the-curb service connectio n plate to the roof curb in accor­dance with the accessory installation instructions. Connec­tions must be installed before unit is set on roof curb.
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 also result in air or water 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.
If gas or electrical connections are to be routed through the bottom of the unit, attach accessory thru-the-bottom service connections to the basepan in accordance with the accessory installation instructions.

B. Alternate Unit Support
When the curb or adapter cannot be used, su pport unit with sleepers using un it curb or adapter supp ort area. If sleeper s cannot be used, support long sides of unit with a minimum of three 4-in. x 4-in. pads, two at the corners and one at the unit’s center of gravity. If more than 3 pads are used, equally space them along the side.
C. Slab Mount (Horizontal Units Only)
Provide a level concrete slab tha t extends a min imum of 6 in. beyond unit cabinet. Ins tall a 6-in. g ravel apron in f ront 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.
II. STEP 2 — FIELD FABRICATE DUCTWORK
Secure all ducts to roof curb and building s tructure on verti ­cal units. Do not connect ductwork to unit. For horizontal applications, field-supplied flanges should be attached to horizontal discharge openings and all ductwork secured to the flanges. Insulate and weatherproof all external duct­work, joints, and roof openings with counter flashing and mastic in accordance with applicable codes.
Ducts passing through a n unc ondit i one d spa ce must be insu­lated 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 appli­cable fire codes.
A minimum clearance is not required around ductwork. Cab­inet return-air static shall not exceed –.30 in. wg with EconoMi$er+ or .45 in. wg without economizer.
These units are designed for a minimum heating operation continuous return-air te mperature of 50 F (dry bulb), o r 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 wh en these lo wer ai r tempera­tures are used with insufficient heating temperature ri se.
III. STEP 3 — INSTALL EXTERNAL TRAP FOR CONDEN­SATE DRAIN
The unit’s
3
/4-in. condensate drain connections ar e located on the bottom and side of the unit. Unit discharge connections do not determine the use of drain connections; either drain connection 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 connection to the side connection. 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 a minimum of 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
/4 in.). See Fig. 5B .
The center drain plug looks lik e a star conne ctio n, however it can be removed with a
1
/2 in. socket drive extension.
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 Tables 1A and 1B and Fig. 6 for additional inf ormat ion. Op era ting we ight is s hown in Table 1 and Fig. 6.
Lifting holes are provided in base rails as shown in Fig. 1 and 6. Refer to rigging instructions on unit.
CAUTION: Al l panels must be in place wh en rig-
ging and lifting.

V. STEP 5 — INSTALL FLUE HOOD
Flue hood is shipped screwed to 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 equipp ed for use with type of gas shown on name­plate. Refer to local building codes, or in the absence of local codes, to ANSI Z223.1-latest year and addendum Z223.1A­latest year 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 when installing gas piping.
For natural gas applications, gas pressure at unit gas con­nection must not be less than 4.0 in. wg (5.0 in. wg in high heat units) or greater than 13.0 in. wg while unit is operat­ing. For liquid propane applications, the pressure must not be less than 5.0 in. wg or greater than 13.0 in. wg at the unit connection.
Size gas supply piping for 0.5 i n. wg ma ximum pre ssure drop . Do not use supply pip e smaller than unit gas connection.
CAUTION: When installing gas piping to gas valve inlet, use properly sized back-up wrench on inlet flange flats to prevent valve damage.
Support gas piping as shown in the table in Fig. 8. For exam-
3
ple, a
/4-in. gas pipe must have one field-fabricated support
beam every 8 ft. See Fig. 8 for typical pipe guide and locations of external
manual gas shutoff valve. NOTE: If field-installed thru-the-bottom connections are
used, refer to the accessory installation instructions for power wiring and gas connections. Refer to Fig. 1A and 1B for drilling holes in basepan.
VII. STEP 7 — MAKE ELECTRICAL CONNECTIONS
WARNING: Unit cabinet must have an uninter-
rupted, unbroken electrical ground to minimize the possibility of personal injury if an electrical fault should occur. This ground may consist of electric al wir e connected to unit ground lug in control compartment, or conduit approved for electrical ground when installed in accordance with NEC (National Electrical Code), ANSI/NFPA (National Fire Protection Associa­tion), 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 personal injury of other s.
A. Field Power Supply
All units except 208/230-v units are factory wired for the voltage shown on the na meplate. If the 208/230-v u nit is to be connected to a 208-v power supply, the transformer must
1
be rewired by moving the black wire from the 230- v
/4-in. male spade terminal on the transformer and connecting it to the 208-v
1
/4-in. male spade terminal from the transformer.
Refer to unit label diagram for additional information. Pig­tails are provided for field service.
When installing units, provide a disconnect per NEC. Use copper conductors only when splice connectors are used.
All field wiring must comply with NEC and local require­ments. In Canada, electrical connections must be in accor­dance with CSA (Canadian Standards Association) C22.1 Canadian Electrical Code Part One.

Fig.8—GasPipingGuide(With Accessory
Thru-the-Curb Service Connections)
Install conduit through side panel openings indicated in Fig. 1A and 1B. Route power lines through connector to ter­minal connections as shown in Fig. 9.
On 3-phase units, voltages between ph ase s must be balanced within 2% and the current within 10%. Use the formula shown in Tables 2A and 2B, Note 2 to determine the percent­age of voltage im balance. Operation on improper line voltage or excessive phase imbalance constitutes abuse and may cause damage to electrical components. Such operation would invalidate any applicable Bryant warranty.
NOTE: If field-installed thru-the-bottom connections are used, refer to the accessory installation instructions for power wiring and gas connectio ns. Refer to Fig. 1A and 1B for drilling holes in basepan.
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 accor­dance with thermostat installation instructions.
NOTE: For wire runs up to 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 n o. 18 AWG cannot be dir ectly con nect ed to the thermos tat and wi ll req uire a j unction box and s plice a t the thermostat.
12
Route thermostat cable or equivalent single leads of colored wire from thermostat subbase terminals to low-voltage con­nections on unit (shown in Fig. 10) as described in Steps 1-4 below.
If unit is mounted on roof curb and accessory thru-the-curb service plate connection is used, route wire through connec­tion plate.
Pass control wires through the hole provided on unit (see connection D in Connection Sizes table in Fig. 1A and 1 B).
Feed wires through the raceway built into the corner post to the 24-v barrier located on the left side of the control box.

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%.
of voltage imbalance. % Voltage Imbalance
= 100 x
Example: Supply voltage is 460-3-60.
Determine maximum deviation from average voltage.
(AB) 457 – 452 = 5 v (BC) 464 – 457 = 7 v (AC) 457 – 455 = 2 v
Maximum deviation is 7 v.
Determine percent of voltage imbalance.
% Voltage Imbalance = 100 x
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.
Use the following formula to determine the percent
max voltage deviation from average voltage
AB = 452 v BC = 464 v AC = 455 v

NOTE: If a single power source is to be used, size wire to include power exhaust MCA and MOCP. Must be in accordance with NEC or local codes.
Check MCA and MOCP when power exhaust is powered through the unit. 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 580FPV090 unit with MCA = 40.1 and MOCP
= 45, with CRPWREXH030A00 power exhaust. MCA New = 40.1 amps + 1.6 amps = 41.7 amps If the new MCA does not exceed the published MOCP, then MOCP
would not change. The MOCP in this example is 45 amps and the MCA New is below 45; 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$er+ is Outdoor
Dry Bulb Changeover. The outdoor air an d supply air tem­perature sensors are also included as standard. EconoMi$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$er should be in minimum position. If the outdoor-air temperature is below the set point, the position should be controlled to maintain the l eav ing a ir t emper ature set po in t. The s et po int range is 45 to 70 F.
Differential D r y Bulb Changeover The control supports differential dry bulb changeover con-
trol. This requires an accessory return air temperature sensor CRTEMPSN001A00 installed in the return air­stream. Refer to the Start-up section for details on how to configure and enable the control mode. The user can check the operation of the s ensor using the Read function.
Outdoor Air Enthalpy Changeover The control support s ou tdoor air e nthal py cha ngeo ver con trol.
This mode requires a factory-supplied outdoor air temperature sensor (OAT) and an accessory outdoor air humidity sensor (ORH) (part no. CRHUMDSN001B00). Refer to the Start-Up section fo r details on how to con figure and enable th e control mode. The user ca n check the operation of the sensors using the Read function.
Differential Ent halpy Changeover The control supports differential enthalpy changeover con-
trol. This requires the factory-supplied outdoor air tempera­ture sensor, an accessory outdoor air humidity sensor, an accessory return air temperature sensor, and an accessory indoor air humidit y sensor. Refer to the Start-Up section fo r details on how to configure and enable the control mode. The user can check the o peration of the sens ors using the Read function.
D. Damper Movement
When the EconoMi$e r+ board receives initia l power, it will take the damper up to 2
1
/2 minutes before it begins to posi­tion 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 2
1
/2 minutes.
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 con tinue to its 100% open posi­tion before closing.
NOTE: Occupied minimum position can not be set lower than +1% higher than the value of IAQ minimum ec onomizer posi­tion. Refer to the setup examples on page 56.
E. EconoMi$er+ Controller Wiring
The EconoMi$er+ is sup plied fr om the factor y with a suppl y air temperature sensor and an outside air temperature sensor. This allows for operation of the EconoMi$er+ with outdoor air dry bulb changeover control. Additional accesso­ries can be added to allow for different types of change over control and operation of the EconoMi$er+ and unit.
F. T hermostats
The EconoMi$er+ control works with conventional thermo­stats that have a Y1 (cool stage 1), Y2 (cool stage 2), W1 (heat stage 1), W2 (heat stage 2) , and G (fan). The EconoMi$er+ control does not support sensor thermostats l ike the T56 and T57. Connections are made at the thermos tat terminal con­nection board located in the main control box.

The user can read the value of the sensor using the Read mode, described in the EconoMi$er+ Controller section.
I. Indoor Air Quality (IAQ) Sensor
Any indoor air quality or CO 20 mA output can be used as the IAQ sensor. The controller will modulate the outdoor-air damper to provide ventilation based on the sensor output and the IAQ se tting of the con trol­ler. The CO the minimum position (IAQ minimum damper position set point) to the maximum position (occupied minimum damper position). When there is no CO unoccupied minimum pos ition. When there is a CO damper will be between the IAQ minimum economizer set point position and the occup ied min imum da mper pos ition.
Mount the sensor according to manufacturer specifications. In order to wire this sensor, an accessory 5-pin plug (part number CRE+PLUG001A00) is required. See Fig. 22.
The IAQ sensor is wired to the g round an d IAQ w ires in the harness. The accessory 5-pin wiring plug is connected to pins 13-17 of J3 on the EconoMi$er+ controller. Push the plug down onto the pins of the EconoMi$e r+ controller to instal l.

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$er+ changeover and compressor lockout. The sensor is factory-installed on the EconoMi$er+ in the outdoor air­stream. The operating range of temperature measurement is 0° to158 F. See Tables 5 and 6 for thermistor resistan ce and resolution values.
The temperature sensor l ooks 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 . Th e o per ating range of temperature me as ur e­ment is 0° to158 F. See Tables 5 and 6 for thermistor resis­tance and resolution values.
The temperature sensor l ooks like an eyelet terminal with wires running to it. The sensor is located in the “crimp end” and is sealed from moisture.
used for the field-installed remote potentiometer. Connect the IAQ sensor to the BRN and WHT wires o f the accessor y 5-pin plug.
NOTE: Pin numbers are not sh own on th e cont roller. They are provided only as reference for the installer. On the EconoMi$er+ board, they numbered 1-17 from left to right, but only the 1 and the 17 are printed on the board.
Sensor wiring should be extended with wire and wire nuts and routed to the IAQ sensor location. Adjust the IAQ set­ting at the controller to correspond to the IAQ voltage output of the sensor at the user-determined set point. See Fig. 26. Power the sensor with a field-supplied transformer.
J. Return Air Temperature (RAT) Sensor
The EconoMi$er+ controller will accept input from the acces­sory 10K return air temperature sensor (CRTEMPSN001A00) in addition to the outdoor air temperature 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 eye let 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$er+ Controller section.
Mount the return air temp erature sens or on the Eco noMi$er+, through pre-punched holes. See F ig . 2 7.
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 harness should be routed from the EconoMi$er+ controller to the sensor. The controller compares the temper­atures of the two ai rstream s, chooses the be st one, and mod ­ulates the EconoMi$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$er+ controller accepts input from the accessory outdoor air humidity sensor in ad dition to the out door air tem­perature sensor shipped with the EconoMi$er+. By using both sensors, the total ent halpy of the out sid e air is ca lcula ted.
Mount the outdoor-air humidity sensor in to the EconoMi$er+, through the pre-punched holes. See Fig. 28. The outdoor-air humidity senso r is provided with a 2-wire, 42-in. wiring harness with a 2-pin connector. The plug is installed on pins 11 and 12 on J3 of the EconoMi$er+ con­troller. The pins are labeled ORH and VREF on the EconoMi$er+ controller. See Fig. 22. The orange wire of the harness is connected to pin 11 (ORH). The blue wire of the harness is connected to pin 12 (VREF). The wiring harness should be rout ed from the Eco noMi$ er+ cont roll er to the se n­sor location.
The outdoor enthalpy changeover curve is set at the EconoMi$er+ controller. The factory default is curve “A.” See Fig. 29. See Fig. 30 for Sensor Curve vs. Humidity.
L. Indoor Air Humidity Sensor
For differential enthalpy sensing, the EconoMi$er+ control­ler uses the standard outdoor air temperature sensor, the outdoor air humidity sensor, and the optional indoor air humidity sensor, an optional return air t emperature sensor (RAT). The indoor-air humidity sensor is provided with a 2-wire, 42-in. wiring harness with a 2-pin connector. The plug is installed on pins 8 and 9 on J3 of the EconoMi$er+ controller. The pins are labeled IRH and VREF on the EconoMi$er+ controller. See Fig. 22. The orange wire of the harness is connected to pin 8 (IRH). The blue wire of th e har­ness is connected to pin 9 (VREF). The wiring harness should be extended with wires and wire nuts and routed from the EconoMi$er+ controller to the sensor location. The EconoMi$er+ controller compares the outdoor air enthalpy to the return air enthalpy to determine EconoMi$er+ use.
The controller select s the lower enthalpy air (return or out­door) for cooling. For example, when the outdoor air has a lower enthalpy than the return air , the EconoMi$er+ control­ler opens the damp er to bring in outdoor air for free cooling.
Mount the return-air humidity sensor in the return-air duct. See Fig. 31.
The outdoor enthalpy changeover curve is set with at the EconoMi$er+ controller. The selectable curves are A, B, C, and D. The factory default is curve “A.” See Fig. 29. See Fig. 30 for Sensor Curve vs. Humidity.
