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 sh o uld be perfor me d by trai ne d se rvi ce per­sonnel. 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 opera tions.
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 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.
WARNING: Before performing service or mainte­nance 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 p r ov ided fo r t he unit .
Unit is ship ped in t he ve rti cal d uc t con figu rat ion . To convert t o 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 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 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 roo f curb.
If electric and control wiring is to be routed through the basepan, attach the accessory thru-the-bottom service con­nections 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.

B. Slab Mount (Horizontal Units Only)
Provide a level concrete slab tha t extends a minimum of 6 in. beyond unit cabi ne t. I nsta ll a grav el apr on in f ron t of con dens er 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 sleepe r 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 s tructure on verti ­cal ducted units. Do not connect ductwork to unit. For h or i­zontal applications, fiel d-supplie d flanges sh ould b e attach ed to horizontal duct openings and all ductwork should be secured to the flanges. Insulate and weatherproof all exter­nal ductwork, joints , and roo f 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 pressure (a negative condition) should not exceed 0.35 in. wg with economizer or 0.45 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 tempera­tures are used with insufficient heating temperature rise.
III. STEP 3 — INSTALL EXTERNAL TRAP FOR CONDEN­SATE 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 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-i nstalle d plug (Re d) from t he bott om con­nection to the side connection. The center dr ain plug l ooks 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 fr om the unit at 1 in. per 10 ft of r un. Do not use a pipe size smaller than the unit connection (
3
/4 in.). 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 ref erence. See Table 1 and Fi g. 6 for additional information.
Lifting holes are provided in base rails as shown in Fig. 1A and 1B. Refer to rigging instructions on unit.
CAUTION: All panels must be in place when rigging. Unit is not designed for handling by a fork truck. Damage to unit may result.

A. Positioning
Maintain cleara nce around and abov e unit to provide mini ­mum distance from combustible materials, proper airflow, and service access. See Fi g. 1A and 1B. A properly positioned unit will have the fol lo wing c l ea ranc es be twe en uni t and r o of
1
curb:
/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.)
Do not install unit in an indoor location. Do not locate unit air inlets near exhaust vents or other sources of contami­nated 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 clear­ance 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 . Orie nt unit suc h 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 Combus­tion and Ventilation, NFGC (National Fuel Gas Code), and ANSI (American National Standards Institute) Z223.1, and NFPA (National Fire Protectio n As so ci atio n) 5 4 TI A -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 wi th type of gas shown on name­plate. 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 con­nection must not be less than 4 in. wg or greater than
13.0 in. wg while unit is oper atin g. On 580F04 8,0 60,072 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 connec­tion. Support gas pipi ng as shown in the ta ble 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
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 electrical wire connected to unit ground lug in control compartment, or conduit approved for electrical ground when installed in accor­dance with NEC (N a tio n al Electrical Code), ANSI/N FPA, 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 p er­sonal injury of others.
BLOWER ACCESS PANEL
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 be rewired by m oving the blac k wire with th e
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 fie ld wire connectio ns. Use factory­supplied 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 foll ows:
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 impr op er lin e volta ge or excess ive phase imbal­ance 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 accor­dance 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

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
CRPWREXH030A01 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.

B. Optional EconoMi$er IV
See Fig. 16 for EconoMi$er IV component locations. NOTE: These instructions are for installing the optional
EconoMi$er IV only. Refer to the accessory EconoM i$er IV installation instructions when field installing an EconoMi$er IV accessory.
1. To remove the existing unit filter access panel, raise the panel and swing the bottom outward. The panel is now disengaged from the track and can be removed. See Fig. 17.
2. The box with the economizer hood components is shipped in the compartment behind the economizer. The EconoMi$er IV controller is mounted on top of the EconoMi$er I V in the position shown in Fig. 16. The optional EconoMi$er2 with 4 to 20 mA actuator signal control does not include the EconoMi$er IV controller. To remove the component box from its shipping position, remove the screw holding the hood box bracket to the top of the economizer. Slide the hood box out of the unit. See Fig. 18.
IMPORTANT: If the power exhaust accessory is to be installed on the unit, the hood shipped with the unit will not be used and must be discarded. Save the aluminum filter
for use in the power exhaust hood assembly.
3. The indoor coil access panel will be used as the top of the hood. Remove the screws along the sides an d bot­tom of the indoor coil access panel. See Fig. 19.
4. Swing out indoor coil access panel and insert the hood sides under the panel (hood top). Use the screws provided to attach the hood sides to the hood top. Use screws provided to attach the hoo d sides to the unit. See Fig. 20.
5. Remove the shipping tape holding the economizer barometric relief damper in place.
6. Insert the ho od divider between the hood s ides. See Fig. 20 and 21. Secure hood divider with 2 screws on each hood side. The hood divider is also used as the bottom filter rack for the aluminum filter.
7. Open the filter clips which are located underneath the hood top. Insert the aluminum filter into the bot­tom filter rack (hood divider). Push the filter into po­sition past the op en filter clips. Close the fi lter clips to lock the filter into place. See Fig. 21.
8. Caulk the ends of the joint between the unit top panel and the hood top. See Fig. 19.
9. Replace the filter access panel.
10. Install all EconoMi$er IV accessories. EconoMi$er IV wiring is shown in Fig. 22.
Barometric flow capacity is shown in Fig. 23. Outdoor air leakage is shown in Fig. 24. Return air pressure drop is shown in Fig. 25.
