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 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 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.
Recognize safety information. This is the safety--alert symbol
. When you see this symbol on the unit and in instructions or
manuals, be alert to the potential for personal injury.
Understand the signal words DANGER, WARNING, and
CAUTION. These words are used with the safety--alert symbol.
DANGER identifies the most serious hazards which will result in
severe personal injury or death. WARNING signifies a hazard
which could result in personal injury or death. CAUTION is used
to identify unsafe practices which may result in minor personal
injury or product and property damage. NOTE is used to
highlight suggestions which will result in enhanced installation,
reliability,or operation.
!
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could cause personal
injury or death.
Before performing service or maintenance operations
on unit, turn off main power switch to unit and install
lockout tag. Ensure electrical service to rooftop unit
agrees with voltage and amperage listed on the unit
rating plate.
WARNING
INSTALLATION
Unit is shipped in the vertical discharge configuration. To convert
to horizontal discharge application, remove duct opening covers.
Using the same screws, install covers on duct openings in
basepan of unit with insulation-side down. Seals around
openings must be tight. (See Fig. 1.)
1
Step 1 —Provide Unit Support
Roof Curb
Assemble and install accessory roof curb in accordance with
instructions shipped with curb. (See Fig. 2.) Install insulation,
cant strips, roofing felt, and counter flashing as shown. Ductwork
must be attached to curb, not to the unit. If electric control power
or gas service 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.
Connections must be installed before unit is set on roof curb.
551B,C
Fig. 1 --- Horizontal Conversion Panels
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. 2. Improperly applied gasket can result in
air leaks and poor unit performance.
Curb should be level. Unit leveling tolerances are shown in Fig.
3. This is necessary for unit drain to function properly. Refer to
Accessory Roof Curb Installation Instructions for additional
information as required.
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.
Alternate Unit
When the curb or adapter cannot be used, support unit with
sleeper rails using unit curb or adapter 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.
Support
C06108
Step 2 —Field Fabricate Ductwork
Secure all ducts to roof curb and building structure on vertical
discharge units. Do not connect ductwork to unit. For horizontal
applications, field-supplied isolation flanges should be attached to
horizontal discharge openings and all ductwork should be 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 an unconditioned space 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) shall not exceed
0.35 in. wg with economizer or 0.45 in. wg without economizer.
Step 3 —Install External Trap for Condensate
Drain
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, ensure 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. The center drain plug looks
like a star connection, however it can be removed with a
socket drive extension. (See Fig. 4.) 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 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. 5.)
1
/2-in.
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, 2 and Fig. 6 for additional
information. Operating weight is shown in Table 1, 2 and Fig. 6.
Lifting holes are provided in base rails as shown in Fig. 7. Refer
to rigging instructions on unit.

ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal
injury or death.
Unit cabinet must have an uninterrupted, 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 (National Electrical Code), ANSI/NFPA (National
Fire Protection Association), latest edition, and local
electrical codes. Do not use gas piping as an electrical
ground.
Field Power Supply
551B,C
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. terminal on
the transformer and connecting it to the 200-v 1/4--in. terminal
from the transformer.
Refer to unit label diagram for additional information. Pigtails
are provided for field service. Use factory-supplied splices or UL
(Underwriters’ Laboratories) approved copper connector.
When installing units, provide a disconnect per NEC.
All field wiring must comply with NEC and local
requirements.
Install field wiring as follows:
1. Install conduit through side panel openings. For units
without electric heat, install conduit between disconnect
and control box.
2. Install power lines to terminal connections as shown in
Fig. 12.
3. For units with electric heat, refer to Accessory Electric
Heat Installation Instructions.
During operation, voltage to compressor terminals must be within
range indicated on unit nameplate (also see Table 3 and 4). On
3--phase units, voltages between phases must be balanced within
2% and the current within 10%. Use the formula shown in Table
3 and 4, Note 2, to determine the percentage of voltage
imbalance. Operation on improper line voltage or excessive phase
imbalance constitutes abuse and may cause damage to electrical
components. Such operation invalidates any applicable Bryant
warranty.
NOTE: If accessory thru-the-bottom connections and roof curb
are used, refer to the Thru-the-Bottom Accessory Installation
Instructions for information on wiring the unit.
WARNING
Field Control W
iring
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.
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 to 50 ft, use no. 18 AWG (American
Wire Gauge) insulated wire (35_Cminimum).For50to75ft,use
no. 16 AWG insulated wire (35_C minimum). For over 75 ft, use
no. 14 AWG insulated wire (35_C minimum). All wires larger
than no. 18 AWG cannot be directly connected to the thermostat
and will require a junction box and splice at the thermostat.
1. Connect thermostat wires to screw terminals of low
voltage terminal board.
2. Pass the control wires through the hole provided in the
control box.
3. Some models may be equipped with a raceway built into
the corner post on the left side of control box (See Fig.
12.) This raceway provides the required clearance between
high-- voltage and low voltage wiring. For models without
a raceway, ensure to provide the NEC required clearance
between high-- voltage and low--voltage wiring.
