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 may
apply.
Follow all safety codes. Wear safety glasses and work gloves.
Use quenching cloth for unbrazing operations. Have fire
extinguisher available for all brazing operations.
INSTALLATION
Unit is shipped in the vertical discharge configuration. To
convert to horizontal configuration, remove horizontal duct
opening covers. Using the same screws, install covers on duct
openings in basepan of unit with the insulation-side down.
Seals around duct openings must be tight.
I. STEP 1 — PROVIDE UNIT SUPPORT
A. Roof Curb
Assemble and install accessory roof curb in accordance with
instructions shipped with curb. See Fig. 1. Install insulation,
cant strips, roofing felt, and counter flashing as shown. Duct-
work must be attached to curb, not to the unit. If electric or
control power is to be routed through the basepan, attach the
accessory thru-the-bottom service connections to the
basepan and 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 watertightness. Install gasket supplied with the
roof curb as shown in Fig. 1. Improperly applied gasket can
also result in air leaks and poor unit performance.
Curb should be level. This is necessary for unit drain to func-
tion properly. Unit leveling tolerances are shown in Fig. 2.
Refer to Accessory Roof Curb Installation Instructions for
additional information as required.
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 con-
denser 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 structure on verti-
cal discharge units. Do not connect ductwork to unit. For hor-
izontal applications, field-supplied flanges should be
attached to horizontal discharge openings and all ductwork
should be attached 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 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 to combustibles is not required around
ductwork on vertical discharge units. On horizontal dis-
charge units with electric heat, a minimum clearance of
1.0 in. is required for the first 12 in. of ductwork. Cabinet
return-air static pressure should not exceed –0.35 in. wg
with Durablade economizer, –0.30 in. wg with EconoMi$er,
or –0.45 in. wg without economizer.
III. STEP 3 — INSTALL CONDENSATE DRAIN LINE AND
EXTERNAL TRAP
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 discharge units.
When using the standard side drain connection, make sure
the plug in the alternate bottom connection is tight before
installing the unit.
To use the bottom drain connection for a roof curb installa-
tion, relocate the factory-installed plug from the bottom con-
nection to the side connection. See Fig. 3. 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 drain-
age. 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 548F unit at 1 in.
per 10 ft of run. Do not use a pipe size smaller than the unit
connection.
IV. STEP 4 — RIG AND PLACE UNIT
Inspect unit for transportation damage, and 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, and rollers may be used to move unit across a roof.
Level by using unit frame as a reference. See Table 1 and
Fig. 4 for additional information. Operating weight is shown
in Table 1 and Fig. 4.
Lifting holes are provided in base rails as shown in Fig. 4
and 5. Refer to rigging instructions on unit.
A. Positioning
Maintain clearance around and above unit to provide proper
airflow and service access. See Fig. 5.
A properly positioned unit will have the following clearances:
1/4-in. clearance between roof curb and base rails on each
side and front of unit; 1/4-in. clearance between roof curb and
rear of unit. (See Fig. 1, section C-C.)
Do not install unit in an indoor location. Do not locate unit
air inlets near exhaust vents or other sources of contami-
nated air.
Although unit is weatherproof, guard against water from
higher level runoff and overhangs.
After unit is in position, remove polyethylene shipping wrap-
per and top crating.

V. STEP 5 — 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 disconnecting the black wire from the 230-v
1/4-in. male spade terminal on the transformer and connect-
ing 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 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 the NEC and local
requirements.
Install field wiring as follows:
1. Install conduit through side panel openings. For units
without electric heat, install conduit between discon-
nect and control box.
2. Install power lines to terminal connections as shown
in Fig. 6.
3. For units with electric heat, refer to Accessory Elec-
tric Heat Installation Instructions.
During operation, voltage to compressor terminals must be
within range indicated on unit nameplate (also see Tables 2A
and 2B). On 3-phase units, voltages between phases must be
balanced within 2% and the current within 10%. Use the for-
mula shown in Tables 2A and 2B, Note 2, on page 12 to
determine the percentage of voltage imbalance. Operation on
improper line voltage or excessive phase imbalance consti-
tutes abuse and may cause damage to electrical components.
Such operation invalidates any applicable Bryant warranty.
NOTE: If accessory thru-the-bottom connections and roof
curbs are used, refer to the thru-the-bottom accessory instal-
lation instructions for information on wiring the unit.

NOTES:
1. Dimension in ( ) is in millimeters.
2. Hook rigging shackles through holes in base rail, as shown in
detail ‘‘A.’’ Holes in base rails are centered around the unit center
of gravity. Use wooden top skid when rigging to prevent rigging
straps from damaging unit.
3. Unit weights do not include economizer. See Table 1 for econo-
mizer weights.
CAUTION: All panels must be in place when rigging and
lifting.

a. Bottom of unit to combustible surfaces (when not using curb) 0 inch,
on horizontal discharge units with electric heat 1 in. clearance to duct- work for 1 ft.
b. Outdoor coil, for proper airflow, 36 in. one side, 12 in. the other. The
side getting the greater clearance is optional.
c. Overhead, 60 in. to assure proper outdoor fan operation.
d. Between units, control box side, 42 in. per NEC (National Electrical
Code).
e. Between unit and ungrounded surfaces, control box side, 36 in. per
NEC.
f. Between unit and block or concrete walls and other grounded sur-
faces, control box side, 42 in. per NEC.
g. Horizontal supply and return end, 0 inches.
6. With the exception of the clearance for the outdoor coil and combustion side
as stated in Notes 5a, b, and c, a removable fence or barricade requires no clearance.
7. Units may be installed on combustible floors made from wood or Class A, B,
or C roof covering material if set on base rail.
8. The vertical center of gravity is 1′-61/2″[470] up from the bottom of the base
rail.
