SAFETY CONSIDERATIONS
Installation and servicing of air-conditioning equ ipment can
be hazardous due to system pressure and electrical components. Only trained and qualified service personnel should
install, repair , or service 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 se rvice personnel. When working on air-conditioning equipment, observe
precautions in the literature, tags and labels attached to the
unit, and other safety pre c au ti ons th at ma y a ppl y.
Follow all safety codes. Wear safety glasses and work gloves.
Use quenching cloth for unbrazing operations. Have fire extinguishers available for all brazing operations.
WARNING: Before performing service or maintenance operations on unit, turn off main power switch to
unit and install lockout tag to disconnect switch. Electrical shock could cause personal injury.

WAR NING:
1. Improper installation, adjustment, alteration, service, or maintenance can cause property damage,
personal injury, or loss of life. Refer to the User’s
Information Manual provided with this unit for
more details.
2. Do not store or use gasoline or other flammable
vapors and liquids in the vicinity of this or any
other appliance.
What to do if you smell gas:
1. DO NOT try to light any appliance.
2. DO NOT touch any electrical switch, or use any
phone in your building.
3. IMMEDIATELY call your gas supplier from
a neighbor’s phone. Follow the gas supplier’s
instructions.
4. If you cannot reach your gas sup plier, call the fire
department.
WAR NING: Disconnect gas piping from unit when
pressure testing at p ressure greater than 0.5 psig. Pressures greater than 0.5 psig will cause gas valve damage
resulting in hazardous condition. If gas valve is subjected
to pressure greater than 0.5 psig, it must be replaced
before use. When pressure testing field-supplied gas piping at pressures of 0.5 psig or less, a unit connected to
such piping must be isolated by closing th e manual gas
valve(s).
IMPORTANT: Units have high ambient operating limits. If
limits are exceeded, the units will au tomatically lock the compressor out of operation. Manual reset will be required to
restart the compressor.
INSTALLATION
I. STEP 1 — PROVIDE UNIT SUPPORT
A. Roof Curb
Assemble or install accessory roof curb or horizontal adapter
roof curb in accordance with instructions shipped with this
accessory. See Fig. 1A, 1B, and 2. Install insulation, cant
strips, roofing, and counter flashing as shown. Ductwork can
be installed to roof curb or horizontal adapter roof curb before
unit is set in place. Curb or adapter roof curb shoul d be level.
This is necessary to permit unit drain to function properly.
Unit leveling tolerance is ±
tion. Refer to Accessory Roof Curb or Horizontal Adapter Roof
Curb Installation Instructions for additional information as
required. When accessory roof curb or horizontal adapter roof
curb is used, unit may be installed on class A, B, or C roof covering material.

IMPORTANT: The gasketing of the unit to the roof curb or
adapter roof curb is critical for a watertight seal. Install
gasket with the roof curb or adapter as shown in Fig. 1A and
1B. Improperly applied gasket can also result in air leaks
and poor unit performance.
B. Alternate Unit Support
When the curb or ada pter cannot be used, install unit on a
noncombustible surface. Support unit with sleepers, using
unit curb support area. If sleepers cannot be used, support
long sides of unit with a minimum of 3 equally spaced 4-in. x
4-in. pads on each side.
II. STEP 2 — RIG AND PLACE UNIT
Inspect unit for transportation damage. File any claim with
transportation agency.
Do not drop unit; keep upr ight. Use sprea der bars over unit
to prevent sling or cable damage. Rollers may be used to
move unit across a roof. Level by using unit frame a s a reference; leveling tolerance is ±

Fig. 14 — Field Gas Piping
IX. STEP 9 — MAKE ELECTRICAL CONNECTIONS
A. Field Power Supply
Unit is factory wired for voltage shown on unit nameplate.
When installing units, provide a disconnect per NEC
(National Electrical Code) requirements of adequate size
(Table 5).
All field wiring must comply with NEC and local
requirements.
Route power and ground lines through control box end
panel or unit basepan (see Fig. 4-6) to connections as shown
on unit wiring diagram and Fig. 15.
CAUTION: The correct power phasing is critical in
the operation of the scroll compressors. An incorrect
phasing will cause the compressor to rotate in the
wrong direction. This may lead to premature compressor failure.
WARNING: The unit must be electrically grounded
in accordance with local codes and NEC ANSI/ NF PA 70
(National Fire Protection Association).
Field wiring must conform to temperature limitations for
type ‘‘T’’ wire. All field wiring must comply with NEC and
local require ments.
Transformer no. 1 is wi r ed for 230 -v unit. If 2 08/230-v unit is
to be run with 208-v power supply, the transfo rmer must be
rewired as follows:
1. Remove cap from red (208 v) wire.
2. Remove cap from orange (230 v) spliced wire.
3. Replace orange wire with red wire.
4. Recap both wires.
IMPORTANT: BE CERTAIN UNUSED WIRES ARE
CAPPED. Failure to do so may damage the transformers.
Operating voltage to compressor must be within voltage
range indicated on unit nameplate. On 3-phase units, voltages between phases must be balanced within 2%.
Unit failure as a res ult of ope ra tio n o n imp ro per line volt age
or excessive phase imbalance constitutes abuse and may
cause damage to electrical components.
B. Field Control Wiring
Install a Bryant-approv ed acces sory ther mosta t assemb ly (or
light commercial Thermidistat™ device for units equipped
with Perfect Humidity™ option) according to the installation
instructions included with accessory. Locate thermostat
assembly on a solid interior wall in the conditioned space to
sense average temperature.
Route thermostat cable or equivalent single leads of colored
wire from subbase terminals through conduit in uni t to lowvoltage connections as shown on unit label wiring diagram
and in Fig. 16.
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 no. 18 AWG cannot be directly connected a t
the thermos tat and wi ll req uire a j unction box and s plice a t
the thermostat.
Set heat anticipator settings as follows:
VOLTAGE W1 W2
208/230 0.98 0.44
460 0.80 0.44
Settings may be changed slightly to provide a greater degree
of comfort for a particular installation.
C. Optional Non-Fused Disconnect
On units with the optional non-fused disconnect, incoming
power will be wired into the disconnect switch. Refer to
Fig. 17 for wiring for 100 and 200 amp disconnect switches.
Units with an MOCP (maximum overcurrent protection)
under 100 will use the 100 amp disconnect switch. Units
with an MOCP over 100 will use the 200 amp disconnect
switch. Refer to the applicable disconnect wiring diagram.
To prevent breakage during shipping, the disconnect handle
and shaft are shipped and packaged inside the unit control
box. Install the disconnec t handle before unit operation. To
install the handle and shaft, perform the following procedure:
1. Open the co nt ro l b ox do or and r e mo ve t he handle and
shaft from shipping location.
2. Loosen the Allen bolt located on the disconnect
switch. The bolt is locat ed on the sq uare hole a nd is
used to hold the shaft in place. The shaft cannot be
inserted until the Allen bo lt is moved.
3. Insert the disconnect shaft into the square hole on
the disconnect switch. The end of the shaft is specially cut and the shaft can only be inserted in the
correct orientation.
