SAFETY CONSIDERATIONS
Installation and servicing of air-conditioning equipment can
be hazardous due to system pressure and electric_d compo-
nents. Only trained and qualified service personnel should
install, repair, or service at>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 personnel.
When working on at>conditioning equipment, observe precau-
tions 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 operations.
Disconnect gas piping from unit when leak
testing at pressure greater than 1/2 psig. Pres-
sures greater than 1/2 psig will cause gas
valve damage resulting in hazardous condi-
tion. If gas valve is subjected to pressure
greater than 1/2 psig, it must be replaced
before use. When pressure testing field-
supplied gas piping at pressures of 1/2 psig
or less, a unit connected to such piping must
be isolated by manually closing the gas
valve.
Before performing service or maintenance operations on
unit, turn off main power switch to unit and install a lock-
out tag. Electrical shock could c_mse personal injury.
INSTALLATION
Unit is shipped in the vertical duct configuration. To convert
to horizont_d configuration, remove and save screws fi_m side
duct opening covers and remove covers. Using the same
screws, install covers on veriical duct openings with the
insulation-side down. Seals around duct openings must be
tight. See Fig. 1.
Confimt before installation of unit that voltage, mnperage
and circuit protection requirements listed on unit &tta plate
agree with power supply provided.
Step 1 -- Provide Unit Support
ROOF CURB -- Assemble and install accesso U roof curb in
accor&mce 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.
The accesso O"thru-the-boltom power and gas connection pack-
age must be installed b@re the unit is ,wt on the roo/ curb. If
field-installed (thin-the-roof curb) gas connections tue desired,
use factory-supplied 3/4-in. pipe coupling and gas plate assem-
bly to mount the thin-the-roof curb connection to the roof crag.
Gas connections and power connections to the unit must be
field installed after the unit is installed on the roof 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.
Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.

IMPORTANT: Tile gasketing of tile unit to tile roof curb is ]
critical for a watertight seal. Install gasket supplied with the
roof curb as shown in Fig. 2. hnproperly applied gasket can
result in tdr leaks and pool 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 lequiled.
SLAB MOUNT (Horizontal Units Only) -- Provide a level
conclete slab that extends a minimum of 6 in. beyond unit
cabinet. Install a gravel apron in front of condenser coil air inlet
to prevent gross and foliage from obstructing airflow.
NOTE: Horizontal units may be installed on a roof curb if
required.
ALTERNATE UNIT SUPPORT (Curb or Slab Mount) -- A
non-combustible sleeper rail can be used in the unit curb sup-
port tuea. 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.
Step 2 -- Field Fabricate Ductwork -- Secure all
ducts to roof curb and building structure on vertical ducted
units. Do not connect du(_'ork to unit. For horizontal applica-
tions, field-supplied flanges should be attached to horizontal
duct 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
accor&mce with applicable codes.
Ducts passing through an unconditioned space must be
insulated and covered with a vapor b_uriel:
If a plenum return is used on a vertical unit, the return
should be ducted through the roof deck to comply with applica-
ble fire codes.
I
A minimum clearance is not required around ductwork.
Cabinet return air static pressme (a negative condition) shall
not exceed 0.35 in. wg with economizer or 0.45 in. wg without
economizeE
These units tue designed for a minimum continuous heating
return-air temperature of 50 F (dry bulb), or an intermittent
operation down to 45 F (@ bulb), such as when used with a
night set-back thermostat. To operate at lower return-air tem-
peratures, a field-supplied outdoor air temperature control must
be used to initiate both stages of heat when the temperature is
below 45 E Indoor comfort may be compromised when these
lower air temperatures are used with insufficient heating tem-
perature rise.
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 con-
nections do not deterraine the use of drain connections; either
dnun connection can be used with vertic;d or horizont;d
applications.
When using the standard side &'ain connection, make sure
the plug (Red) in the ;alternate bottom connection is tight before
inst;dling the unit.
To use the bottom drain connection for a roof curb installa-
tion, relocate the factory-installed plug (Red) from the bottom
connection to the side connection. The center &'ain plug looks
like a stm"connection, however it can be removed with a l/2-in.
socket drive extension. See Fig. 4A. The piping for the conden-
sate &'ain and external trap can be completed after the unit is in
place. See Fig. 4B.
All units must have an exWrnal trap./(_r condensaW druin-

Minimum distance between unit and other electrically live
parts is 48 inches.
Flue gas can deteriorate building materials. Orient unit
such that flue gas will not affect building materials. Locate
mechanical draft system flue assembly at least 48 in. fiom an
adjacent building or combustible materi_d.
Adequate combustion-air and ventilation-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 Stan&rds Institute)
Z223.1, and NFPA (National File Protection Association)
54 TIA-54-84-1. In Cana&t, installation must be in accordance
with the CANI-BI49 inst_dlation codes for gas burning
appliances.
After unit is in position, remove rigging skids and shipping
materials.
Step 6 -- Install Gas Piping -- Unit is equipped for
use with type of gas shown on nameplate. Refer to local build-
ing codes, or in the absence of local codes, to ANSI Z223.1
entitled National Fuel Gas Code. In Cana&t, installation must
be in accordance with the CANI.BI49A and CANI.BI49.2
installation codes for gas burning appliances.
For natural gas applications, gas pressuw at unit gas con-
nection must not be less titan 4 in. wg or greaWr than
13.0 in. wg while unit is operating. On 48TF005,006,007 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 .fbr 0.5 in. wg maximum pressure
drop. Do not use supply pipe smNler titan unit gas connection.
Support gas piping as shown in the table in Fig. 8. For exam-
ple, a 3h-in. gas pipe must have one field-fabricated support
beam every 8 ft. Therefore, an 18-1l 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.
When connecting the gas line to the unit gas valve, the
installer MUST use a backup wrench to prevent damage to
the v_flve.
Step 5 -- Install Flue Hood -- Flue hood is shipped
screwed to the basepan beside the burner compmlment access
panel. Remove from shipping location and using screws pro-
vide& install flue hood and screen in location shown in Fig. 7.

Step 7 -- Make Electrical Connections
Unit cabinet must have tin uninterrupted, unbroken electri-
cal ground to minimize the possibility of persomd injury if
an electrical fault should occm: This ground may consist of
electrical wire connected to unit ground lug in control com-
ptu-tment, or conduit approved for electrical ground when
insttdled in accordance with NEC (National Electrical
Code), ANSI/NFPA, latest edition, and local electrical
codes. Do not use gas piping as an electrical ground. Fail-
ure to follow this warning could result in the installer being
liable for personal injury of others.
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 sup-
p13; the tran_fin'mer must be rewired by moving the black wire
with the//4-in, fi, male .s)ga_e connecwr fi'om the 230-volt _on-
nection and moving to the 200-volt l/4-in, mule terminal on the
prima 0" sMe of the tran@n'mel:
Refer to unit label diagrmn for additional information. Pig-
tails are provided for field wire connections. Use factory-
supplied splices or UL (Underwriters' Laboratories) approved
copper/aluminum connector
When installing units, proffde a dis_ onnect per the NEC.
All .field wiring must comply with NEC and lotzd
requirements.
Install field wiring as follows:
1. Install conduit through side panel openings. Install con-
duit 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
bahmced within 2% and the currant within 10%. Use the formu-
la shown in the legend for Tables 2A and 2B, Note 2 to deter-
mine the percent of voltage imbalance. Operation on improper
line voltage or excessive phase imbalance constitutes abuse and
may cause dmnage to electrictd components. Such operation
would invali&tte any applicable Carrier wammty.
FIELD CONTROL WIRING -- Install a Carrier-apl)roved
acc'essoiw thermostat assembly according to installation
instructions included w#h the accessolw Locate thermostat
assembly on a solid wall in the conditione_l space to sense aver-
age temperature in accor&mce with thermostat installation in-
structions. 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
75 It, use no. 14 AWG insulated wire (35 C minimum). All
wire larger than no. 18 AWG cannot be directly connected to
the thermostat and will require a junction box and splice tit the
thermostat.
Pass the control wires through the hole provided in the cor-
ner post; then feed wires through the raceway built into the
corner post to the 24-v barrier located on the left side of the
control box. See Fig. 11. The raceway provides the UL
required clearance between high and low-voltage wiring.
HEAT ANTICIPATOR SETTINGS -- Set heat anticipator
settings tit 0.14 amp for the first stage and 0.14 amp for second-
stage heating, when available.

3. For units with power exhaust: If a single power source is to be used, size wire to include
power exhaust MCA and MOOR Check MCA and MOCP when power exhaust is pow-
ered through the unit (must be in accordance with NED 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 48TF006---5 unit with MCA = 28.9 and MOCP = 35, with
CRPWREXH080A00 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 MOOP 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 MOOP, raise the MOCP to the
next larger size. For separate power, the MOCP for the power exhaust will be 15 amps
per NEC.

3. For units with power exhaust: If a single power source isto be used, size wire to include
power exhaust MCA and MOOR Check MCA and MOCP when power exhaust is pow-
ered through the unit (must be in accordance with NEC and/or local codes). Determine
the new MCA including the power exhaust using the foflowing formula:
MCA New = MCA unit only + MCA of Power Exhaust
For example, using a 48TF006-=-5 unit with MCA = 28.9 and MOCP = 35, with
CRPWREXH030A00 power exhaust.
MCA New = 28.9 amps + 1.6 amps = 30.5 amps
If the new MCA does not exceed the published MOOP, 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.

PREMIERLINK TM CONTROL -- The PremierLink control-
let is compatible with Carrier Comfo]l Network® (CCN) de-
vices. This control is designed to allow users file access and
ability to change factory-defined settings, thus expanding the
function of file standm'd unit control board. Career's diagnostic
standard tier display tools such as Navigator TM or Scrolling
Marquee can be used wifll the PremierLink controlle]:
The PremielLink controller (see Fig. 16A and 16B) requires
the use of a Carrier electronic thermostat or a CCN connection
for time broadcast to initiate its internal timeclock. This is
necessmy for broadcast of time of &ty functions (occupied/
unoccupied). No sensors me supplied with the field-mounted
PremierLink control. The factory-installed PremierLink con-
trol includes only the supply-air sensor (SAT) and the outdoor
air temperature sensor ((-)AT) as stan&trd. An indoor air quality
(CO2) sensor can be added as tin option. Refer to Table 3 for
sensor usage. Refer to Fig. 17 for PremierLink controller
wiring. The PmmierLink control may be mounted in file
control panel or an area below the control panel.
NOTE: PmmierLink controller versions 1.3 and later am
shipped in Sensor mode. If used with a fllermostat, the Pre-
mierLink controller must be configured to Themiostat mode.
Install the Supply Air Temperature Sensor (SAT) -- When
the unit is supplied with a factory-mounted PremierLink con-
trol, the supply-air temperature (SAT) sensor (33ZCSENSAT)
is factory-supplied and wimdi The wiring is routed from the
PmmierLink control over the control box, through a grommet,
into the fan section, down _flong the back side of the fan, and
along the fan deck over to the supply-air opening.
The SAT probe is wire-tied to the supply-air opening (on the
horizontal opening end) in its shipping position. Remove the
sensor for installation. Re-position the sensor in the flange of
the supply-air opening or in the supply air duct (as required by
local codes). Drill or punch a l/2-in, hole in the flange or duct.
Use two field-supplied, self-drilling screws to secure the sensor
probe in a horizontal orientation.
NOTE: The sensor must be mounted in the dischmge airstream
downstream of the cooling coil and any heating devices. Be
sure the probe tip does not come in contact with tiny of the unit
or heat surfaces.
Outdoor Air Temperature Sensor (OAT) -- When the unit is
supplied with a factoq-mounted PremierLink control, the
outdoor-air temperature sensor (OAT) is factory-supplied and
wired.
Install the Indoor Air Quality (COp) Sensor -- Mount the
optional indoor air quality (CO2) sensor according to manufac-
turer specifications.
A separate field-supplied transformer must be used to pow-
er the CO2 sensor
Wire the CO2 sensor to the COM and IAQI terminals of J5
on the PremierLink controflel: Refer to the PremierLink Instal-
lation, Start-up, and Configuration Instructions for detailed
wiring and configuration information.

Enthalpy Sensors and Control i The enthalpy control
(HH57AC077) is supplied as a t]eld-inst_dled accessory to be
used with the EconoMi$er2 damper control option. The out-
door air enthalpy sensor is pall of die enthalpy control. The
separate field-installed accessory return tdr enthalpy sensor
(HH57AC078) is required for differential enthalpy control.
NOTE: The enthalpy control must be set to the "D" setting for
diffelential enthalpy control to won properly.
The enthalpy control receives the indoor and return
enthalpy from the outdoor and return air enthalpy sensors and
provides a &y contact switch input to the PremierLinld '_'_
controllel: Ix_cate the controller in place of an existing econo-
mizer controller or near the actuator The mounting plate may
not be needed if existing bracket is used.
A closed contact indicates that outside air is preferred to the
return all: An open contact indicates that die economizer
should remain at minimum position.
