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, including ANSI (American Nation-
al Standards Institute) Z223.1. Wear safety glasses and work
gloves. Use quenching cloth for unbrazing operations. Have
fire extinguisher available for all brazing operations.
WARNING
Before performing service or maintenance operations on
unit, turn off main power switch to unit. Electrical shock
could cause personal injury.
FOR YOUR SAFETY
WHAT TO DO IF YOU SMELL GAS
Do not try to light any appliance. Do not touch any electri-
cal switch; do not use any phone in your building. Immedi-
ately call your gas supplier from a neighbor’s phone.
Follow the gas suppliers instructions. If you cannot reach
your gas supplier, call the fire department.
FOR YOUR SAFETY
Do not store or use gasoline or other flammable vapors and
liquids in the vicinity of this or any other appliance.
WARNING
Improper installation, adjustment, alteration, service, or
maintenance can cause injury or property damage. Refer to
this manual. For assistance or additional information, con-
sult a qualified installer, service agency, or the gas supplier.

INSTALLATION
Step 1 — Perform Jobsite Survey Complete
the following checks before installation.
1. Consult local building codes and the NEC (National
Electrical Code) (ANSI/NFPA [American National Stan-
dards Institute/National Fire Protection Association] 70)
for special installation requirements.
2. Determine unit location (from project plans) or select unit
location.
3. Check for possible overhead obstructions which may in-
terfere with unit lifting or rigging.
Step 2 — Place Unit — Inspect unit for transportation
damage. File claim with transportation agency.
Provide clearance around and above unit for airflow, safety,
and service access. Do not restrict top (area above condenser
fans) in any way. Allow at least 6 ft on all sides for rated perfor-
mance, code compliance, and service. On units equipped with
power exhaust option, high velocity air is exhausted out the
hood. Unit should be positioned with at least 10 ft clearance be-
tween the exhaust hood and any obstruction.
Check unit dimensional drawings for unit arrangement and
minimum performance and service clearances.
Do not install unit in an indoor location. Do not locate air in-
lets near exhaust vents or other sources of contaminated air.
Although unit is weatherproof, guard against water from
higher level runoff and overhangs.
Level by using unit frame as a reference. Physical data is
shown in Tables 1A-9.
Step 3 — Roof Mount Unit — Check building codes
for weight distribution requirements. Unit weight is shown in
Tables 1A-1C and 5. Unit may be mounted on class A, B, or C
roofing material.
ROOF CURB — Assemble and install roof curb as described
in instructions shipped with the accessory. Accessory roof curb
and information required to field fabricate a roof curb is shown
in Fig. 1-5. Install insulation, cant strips, roofing and counter
flashing as required. For unit condensate drain to function
properly, curb must be level or within tolerances shown in
Fig. 1-5.
STEEL BEAMS — If roof curb is not used, support unit with
steel beams along its entire length and then support steel as re-
quired. As a minimum, unit must be supported across its width
at each lifting lug location.
Step 4 — Slab Mount Unit — Provide a level con-
crete slab that extends beyond unit cabinet at least 6 inches.
Make a slab 8 in. thick with 4 in. above grade. Use gravel
apron in front of condenser coil air inlet to prevent grass and
foliage from obstructing airflow. Ensure that slab is of
sufficient height to allow for condensate trap of 4 in. on sizes
030-070 or 7 in. on sizes 075-100.
Step 5 — Install Curb Gasketing
SIZE 030-060 UNITS — After ductwork has been connected
to the roof curb, attach adhesive-backed gasketing on all end
rails, cross rails, and duct rails. Be sure all joints and corners of
gasket are square and flush to prevent possible water leaks.
Follow all applicable building codes.
SIZE 070-100 UNITS — After ductwork has been connected
to the roof curb, apply gasket material (1/2-in. thick x 11/2-in.
wide neoprene) where indicated.
Single-Thickness Gasketing (See Fig. 6-8 for Item Num-
bers) — Apply gasketing in the following places:
1. Along both side rails (1) — 2 places, full length
2. Along return air end rail (2) — 1 place
3. Around return air internal duct flange (3) — 1 or 2 places
4. Around supply air internal duct flanges (4) — 3 places
Double-Thickness Gasketing (See Fig. 6 and 8 and Detail
A-A) — Locate a line 93/4-in. from the supply air end of the
accessory curb. Apply a double-thickness of gasket material
along line per detail A-A.
NOTE: Do not apply gasket material along the outside edge of
the curb (area “X”). This pan area of the curb extends out
beneath the end of the unit’s air handler section; applying gas-
ket here develops a potential water trap area on top of the curb.
Condenser Section Roof Curb (See Fig. 7) — Apply single-
thickness gasket along both side rails (5).
Step 6 — Install Field-Fabricated Ductwork
The 48P2,P3 units are designed for vertical supply/return
only. Field-fabricated ductwork must be attached to the roof
curb, or to the support steel, prior to the final rigging and instal-
lation of the unit. Supply and return duct dimensions are shown
in Fig. 1-3.
To attach ductwork to roof curb, insert duct approximately 10
to 11 in. up into roof curb. Connect ductwork to 14-gage roof
curb material with sheet metal screws driven from inside the duct.
Secure all ducts to the building structure, using flexible duct
connectors between roof curbs and ducts as required. Ducts
passing through an unconditioned space must be insulated and
covered with a vapor barrier. Outlet grilles must not lie directly
below unit discharge.
Design supply duct strong enough to handle expected static
pressures.
Step 7 — Rig Unit — Do not drop unit; keep upright.
Use spreader bars over unit to prevent sling or cable damage.
Sheets of plywood placed along the condenser coils will pro-
vide additional protection. All lifting lugs MUST be used when
lifting unit. Level by using unit frame as a reference. See Fig. 9
and 10 for information. Unit and accessory weights are shown
in Tables 1A-1C and 5. Weight distribution and center of gravi-
ty can be found in Fig. 11.
CAUTION
Disconnect gas piping from units when leak testing at pres-
sures greater than 0.5 psig. Pressures greater than 0.5 psig
will cause gas valve damage resulting in a hazardous
condition. If gas valve is subjected to pressure greater than
0.5 psig, it must be replaced. When pressure testing field-
supplied gas piping at pressures of 0.5 psig or less, the unit
connected to such piping must be isolated by manually
closing the gas valve.
CAUTION
Do not lift unit with forklift truck. Move unit with over-
head rigging only.
WARNING
For vertical supply and return units, tools or parts could
drop into ductwork and cause an injury. Install a 90-degree
elbow in the supply and return ductwork between the unit
and the conditioned space. If a 90-degree elbow cannot be
installed, then a grille of sufficient strength and density
should be installed to prevent objects from falling into the
conditioned space. Failure to follow these instructions
could result in personal injury or property damage due to
falling objects.

Step 8 — Connect Condensate Drain — There
are a total of five drain connections required on each unit: one
primary drain (on right-hand side of the unit) and four second-
ary drains (two on each side of unit).
PRIMARY DRAIN — The primary drain is a 2-in. FPT pipe
connection located on the right-hand side of the unit looking at
the unit from the return air end. See Fig. 12-21. Fig. 22 shows
the additional length of units with an extended chassis.
With field-supplied fittings and pipe sections, plumb the pri-
mary condensate drain to the 2-in. FPT connector on the base
rail. Use a trap height of at least 4-in. for size 030-070 units
and 7-in. for size 075-100 units. See Fig. 23 and 24. Install with
a height dimension of at least 2-in. from the top of the exit pipe
from the trap section to the bottom of the connector. Apply a
bead of RTV or similar sealant around the pipe joint at the con-
nector in the base rail.
SECONDARY DRAINS (Units Installed on
Curb) There are two secondary drain connections on each
side of the unit. See Fig. 25. There are secondary drains on
each side of the unit in the filter section and on each side of the
unit in the supply fan section. There are labels marking each lo-
cation on the unit base rail. See Fig. 12-21.
Locate the four 11/4-in. drain coupling assemblies and
mounting screws (shipped in a bag taped to the basepan in the
supply fan section, located behind the access panel marked
FAN SECTION). The drain couplings are a 10-gage plate with
a 11/4 in. half coupling welded to the plate.
At each secondary drain hole location, there is a 13/8-in.
hole pre-drilled in the bottom of the base rail, surrounded by
four 0.20-in. engagement holes. Install a drain coupling assem-
bly using screws provided at each secondary drain hole loca-
tion. See Fig. 26. Do not attach any drain coupling assemblies
in the condenser section base rail.
Using field-supplied fittings and pipe sections, assemble U-
traps at each secondary drain fitting. See Fig. 27. Provide a
minimum size of ½-in. pipe for secondary drains. Use a trap at
least 4-in. deep for size 030-070 units and 7-in. deep for size
075-100 units. Apply a bead of RTV or similar sealant around
the drain assemblies.
Consult local plumbing codes for direction on joining multi-
ple drain lines. Total size of any combined line does not need
to exceed nominal 2-in. size of primary drain connection.
Fill the U-traps at the secondary drain locations prior to unit
start-up. Also check the U-traps before each cooling season to
ensure the traps are filled and functioning properly.
SECONDARY DRAINS (Units Installed on Steel Beam or
Slab) — There are two secondary drain connections required
on each side of the unit. There are secondary drains on the bot-
tom of the base rail on each side of the unit in the filter section
and on each side of the unit in the supply fan section. There are
labels marking each location on the unit base rail. See Fig. 12-
21. Drain holes will need to be drilled in these locations at the
side of the base rail. The existing secondary drain holes in the
bottom of the base rail must be sealed. Prior to final positioning
of the unit, apply a bead of RTV or similar sealant around each
secondary drain hole in the bottom of the unit base rail. See
Fig. 27. Install the metal seal plates then position the unit into
final location.

Locate the four 11/4-in. drain coupling assemblies and
mounting screws (shipped in a bag taped to the basepan in the
supply fan section, located behind the access panel marked
FAN SECTION). The drain couplings are a 10-gage plate with
a 11/4 in. half coupling welded to the plate.
After final positioning of the unit, perform the following
procedure:
1. At each of the four secondary drain locations (marked
with labels on the unit base rail), position the drain cou-
pling assembly in the side of the base rail. Mark the
screw holes and the drain hole locations on the base rail.
2. Drill holes for drain outlet (use 13/8-in. hole saw) and for
the mounting screws (use 3/16-in. drill bit).
3. Install a drain coupling assembly using screws provided
at each secondary drain hole location.
4. Using field-supplied fittings and pipe sections, assemble
U-traps at each secondary drain fitting. See Fig. 24. Pro-
vide minimum size of ½-in. pipe for secondary drains.
Use a trap at least 4-in. deep for size 030-070 units and
7-in. deep for size 075-100 units.
5. Apply a bead of RTV or similar sealant around the drain
assemblies.
Consult local plumbing codes for direction on joining multi-
ple drain lines. Total size of any combined line does not need to
exceed nominal 2-in. size of primary drain connection.
Fill the U-traps at the secondary drain locations prior to unit
start-up. Also check the U-traps before each cooling season to
ensure the traps are filled and functioning properly.

Step 11 — Route Field Wiring
UNIT SIZES 030-060 Field wiring can be brought into the
unit through the basepan and roof curb or through the corner
post in the side of the unit next to the control box.
A 31/2-in. FPT coupling for field power and a 3/4-in. FPT
coupling for 24 v control wiring are provided in the basepan.
There are two 7/8-in. pilot holes in the corner post as shown on
the certified drawings. Use these holes as pilot holes for mak-
ing the hole for field-supplied conduit in the corner post for
field power wiring.
If field power wiring is brought through the roof curb, route
wiring out through one of the holes to the field-supplied dis-
connect and then back into the unit through the other hole. See
Fig. 38 and 39 for recommended disconnect location.
If power wiring is brought through the side of the unit, route
wiring from field-supplied disconnect through top hole into
unit.
If control wiring is to be brought in through the side of the
unit, a 7/8-in. diameter hole must be drilled in the corner post
next to the control box.
UNIT SIZES 070-100 — Field wiring is brought into the unit
through the bottom of the control box. Wiring can be brought
through the roof curb through field-supplied watertight connec-
tions. See Fig. 40.
A 45/32-in. hole for field power wiring and a 7/8-in. hole for
24 v control wiring are provided in the bottom of the control
box. Field-supplied couplings must be used when routing wir-
ing into the control box.
See Fig. 40 for recommended disconnect location.
Step 12 — Make Field Electrical Connections
POWER WIRING Units are factory wired for the voltage
shown on the unit nameplate. The main terminal block is suit-
able for use with aluminum or copper wires. Maximum wire
size varies according to disconnect size.
Units without Factory-Installed Disconnect — When install-
ing units, provide a disconnect per NEC (National Electrical
Code) of adequate size (MOCP [maximum overcurrent protec-
tion] of unit is on the informative plate). All field wiring must
comply with NEC and all local codes. Size wire based on
MCA (minimum circuit amps) on the unit informative plate.
See Fig. 41 for power wiring connections to the unit power
terminal block and equipment ground. Maximum wire size is
two (2) 500 MCM (maximum wire size) conductors per pole.
Units with Factory-Installed Disconnect — The factory-
installed disconnect is an interlocking, door-type. The discon-
nect handle locks the door when it is in the ON position. The
disconnect handle must be in the OFF position to open the con-
trol box door. The disconnect is located in the control box be-
hind the control box door for all units. See Fig. 42.
All field wiring must comply with NEC and all local codes.
Wire must be sized based on MCA (minimum circuit amps) on
the unit informative plate. See Fig. 43 for power wiring con-
nections to the unit disconnect and equipment ground.
Operating Voltage — Operating voltage to the compressor
must be within the voltage range indicated on the unit name-
plate. Voltages between phases must be balanced within 2%,
and the current must be balanced within 10%. See Tables 10-25
for unit electrical data.
Use the following formula to determine the percentage of
voltage imbalance.
Voltage Imbalance
Example: Supply voltage is 460-3-60.
AB = 452 v
BC = 464 v
AC = 455 v
Determine maximum deviation from average voltage:
(AB) 457 – 452 = 5 v
(BC) 464 – 457 = 7 v
(AC) 457 – 455 = 2 v
Maximum deviation is 7 v.
Determine percent voltage imbalance:
= 1.53%
This amount of phase imbalance is satisfactory as it is be-
low the maximum allowable 2%.
Unit failure as a result of operation on improper line voltage
or excessive phase imbalance constitutes abuse and may cause
damage to electrical components.
CAUTION
Use care when drilling near condenser coil. Damage to unit
could result.
IMPORTANT: Units with VFDs (variable frequency
drives) generate, use, and can radiate radio frequency
energy. If units are not installed and used in accordance
with these instructions, they may cause radio interfer-
ence. They have been tested and found to comply with
limits of a Class A computing device as defined by FCC
(Federal Communications Commission) regulations,
Subpart J of Part 15, which are designed to provide rea-
sonable protection against such interference when oper-
ated in a commercial environment.

Step 13 — Connect Air Pressure Tubing — Be-
fore options such as the variable frequency drive (VFD) and/or
modulating power exhaust can operate properly, the pneumatic
tubing for pressure sensing must be installed. Use fire-retardant
plenum tubing (field-supplied). All control devices use 1/4-in.
tubing. Tubing must be run from the appropriate sensing loca-
tion (in the duct or in the building space) to the control device
location in the unit.
VARIABLE FREQUENCY DRIVE — The tubing for the
duct pressure (DP) control option should sample supply duct
pressure approximately 2/3 of the way out from the unit in the
main trunk duct, at a location where a constant duct pressure is
desired.
On these units, the duct pressure is sensed by a pressure
transducer. The pressure transducer output is directed to the unit
control module. On all sizes, the DP transducer is located in the
unit auxiliary control box. See Fig. 44 and 45 for auxiliary
control box location. See Fig. 46-48 for auxiliary control box
details. Use a nominal 1/4-in. plastic tubing.
Refer to appropriate base unit Controls and Troubleshooting
book for instructions on adjusting set points for duct pressure
controls.
MODULATING POWER EXHAUST — The tubing for the
building pressure (BP) control (achieved via the modulating
power exhaust option) should sample building pressure in the
area near the entrance lobby (or other appropriate and sensitive
location) so that location is controlled as closely to design pres-
sures as possible.
These units use a pressure transducer for sensing building
pressure. The BP transducer is located in the unit auxiliary con-
trol box. See Fig. 44 and 45 for auxiliary control box location.
See Fig. 46 and 47 for auxiliary control box details. Use a nom-
inal 1/4-in. plastic tubing.
For instructions on adjusting BP control set points, refer to
the Controls and Troubleshooting book.
RETURN FAN POWER EXHAUST — The tubing for the
building pressure (BP) control (achieved via the return power
exhaust option) should sample building pressure in the area
near the entrance lobby (or other appropriate and sensitive lo-
cation) so that location is controlled as closely to design pres-
sures as possible.
The units use a pressure transducer for sensing building
pressure. The BP transducer is located in the unit auxiliary con-
trol box. See Fig. 45 for auxiliary control box location. See
Fig. 48 for auxiliary control box details. Use a nominal 1/4 in.
plastic tubing.
For instructions on adjusting BP control set points, refer to
the Controls and Troubleshooting book.

Step 16 — Connect Gas Piping — Unit is
equipped for use with natural gas only. Installation must con-
form with local building codes, or in the absence of local
codes, with the National Fuel Gas Code (NFGC), ANSI
Z223.1.
A 1/8-in. NPT tapping plug, accessible for test gage connec-
tion, must be field installed immediately upstream of gas sup-
ply connection to unit, but after manual gas valve. See Fig. 53.
Natural gas pressure at unit gas connection must not be less
than 5 in. wg or greater than 13 in. wg.
Size gas supply piping for 0.5 in. wg maximum pressure
drop. Do not use supply pipe smaller than unit gas connection.
Step 17 — Configure Optional Staged Gas
or Modulating Gas Control — The 48P Series large

Step 18 — Install Flue/Inlet Hoods and
Baffles — The flue/inlet hoods and baffles are shipped in a
package taped to the basepan in the fan section. The flue (out-
let) hoods are pre-assembled. The flue deflector, inlet hoods,
and baffles require assembly.
The hoods are located on the heating section access panel as
shown in Fig. 54 (sizes 030-050), Fig. 55 (sizes 055-100 with
low heat and vertical supply), Fig. 56 (sizes 055-100 with low
heat and horizontal supply), and Fig. 57 (sizes 055-100 with
high heat). The inlet baffles are located inside the access panel
as illustrated in Fig. 58 (sizes 030-050), Fig. 59 (sizes 055-100
with modulating low heat and horizontal supply), and Fig. 60
(sizes 055-100 with modulating high heat). See Table 26 for a
list of parts used to assemble each hood and quantities of each
hood type and baffle used with each unit.
1. Remove shipping block-offs and shipping tape from all
openings in the access panel.
2. Attach flue outlet hoods (see Fig. 61) to access panel us-
ing screws provided. Hoods are placed over each com-
bustion outlet.
3. Install flue deflector baffle inside flue deflector hood. See
Fig 62 for V-type deflector and Fig. 63 for curve-type
deflector. For V-type deflector, screw the baffle and hood
together with screw provided. Refer to Table 26 for
usage.
4. Install flue deflector hood assembly over each flue outlet
hood. See Fig. 64. Observe the offset mounting hole loca-
tions in the deflector hood flanges when attaching hood to
panel. Holes in the mounting flange must be at the bottom
when attached.
5. Inlet hoods are shipped unassembled and must be assem-
bled on the access panel (see Fig. 65-67). Flanges of the
hood top and sides should be installed on the inside of the
access panel openings with the screws provided. The
sides should be placed on the inside of top hoods for all
hood assemblies (6-in., 14-in., and 30-in.). Attach speed
clips to screen. Insert screen into bottom opening of 6-in.
and 14-in. hoods and secure it with 3 screws. To ease the
installation, the 30-in. hood screen may be inserted from
inside of access panel (gas section door) into bottom
opening of hood. Secure with 5 screws. Attached view
port cover over 14-in. inlet hood opening (Fig. 66). Se-
cure with two screws.
6. Install inlet baffle on the access panel with the screw(s)
provided. See Fig. 68 for 14-in baffle and Fig. 69 for
30-in baffle. Attach 14-in baffle from the outside of the
access panel. The 30-in baffle should be installed from in-
side of the access panel. Secure with three screws.
Step 19 — Install Supply-Air Thermistors
(Staged and Modulating Gas Units Only) —

Step 20 — Install Optional Motormaster® V
Control — The Motormaster V control is a motor speed
control device which adjusts condenser fan motor speed in re-
sponse to varying liquid refrigerant pressure. A properly applied
Motormaster V control extends the operating range of air-condi-
tioning systems and permits operation at lower outdoor ambient
temperatures.
The optional Motormaster V controls are factory-installed.
Field-fabricated and installed wind baffles are also required for
units in areas with prevailing winds of more than 5 mph and
where temperatures drop below 32 F. The Motormaster V con-
trol permits operation of the unit to an ambient temperature of
–20 F. The control regulates the speed of one or two 3-phase fan
motors depending on unit size. Replacement of the fan motor on
most units is not necessary.
INSTALL FIELD-FABRICATED WIND BAFFLES
On size 040-060 units, in areas with prevailing winds of
more than 5 mph and where temperatures drop below 32 F,
wind baffles must be field fabricated to ensure proper cooling
cycle operation at low-ambient temperatures with Motormaster
V controls. Wind baffles are not needed on size 030, 035, and
070-100 units. See Fig. 70 for baffle details. Use 20-gage galva-
nized sheet metal, or similar corrosion-resistant material for the
baffles. Use field-supplied screws to attach baffles to unit.
Screws should be 1/4-in. diameter or larger. Screws should not
be more than 1/2-inch in length. Drill required screw holes for
mounting baffles.

CEM (controls expansion module)
Navigator™ hand-held display
CONTROL WIRING The unit can be controlled with a
Carrier-approved accessory electro-mechanical or electronic
thermostat that has two stages of cooling, two stages of heating
control, and an output for fan control. The thermostat may also
include time of day scheduling or use scheduling routines built
into the ComfortLink™ controls.
Install the thermostat according to the installation instruc-
tions shipped with the accessory thermostat. Locate thermostat
assembly on a solid interior wall to sense average temperature.
Route thermostat cable or equivalent leads of colored wire
from subbase terminals through conduit into the low voltage
connections in the main control box. For thermostat TB201
connections, see Fig. 71.
NOTE: For wire runs up to 50 ft, use no. 18 AWG (American
Wire Gage) 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 at the thermostat
and will require a junction box and splice at the thermostat.
Variable Air Volume (VAV) Units — The 48P3,P5
units may be used in applications with additional control fea-
tures, options, or accessories. Refer to the appropriate accesso-
ry installation instructions for more information on installing
that accessory. Refer to the Controls and Troubleshooting man-
ual for more information concerning installation and configura-
tion of options and accessories. Control options and accessories
available for VAV units are:
enthalpy sensor
enthalpy switch
relative humidity sensor
CEM (controls expansion module)
Navigator hand-held display
VAV CONTROL WIRING The recommended types of
control wiring are shown below:
SENSORS — Sensors should be wired using single twisted
pairs of 20 AWG (American Wire Gage) conductor cable rated
for the application, except for the T-56 accessory sensor which
requires 3-conductor cable.
HUMIDITY CONTROL AND HOT WATER AND
STEAM VALVES — These devices require 20 AWG twisted
pair conductor cables rated for the application for the 4 to
20 mA signal.
SPACE TEMPERATURE SENSOR (T-55) — The space tem-
perature sensor (P/N 33ZCT55SPT), if used, is wired to termi-
nals in the unit main control box. To connect the space temper-
ature sensor, see Fig. 72.
SPACE TEMPERATURE SENSOR (T-56) — The space tem-
perature sensor (P/N 33ZCT56SPT), if used, is wired to termi-
nals in the unit main control box. To connect the space temper-
ature sensor, see Fig. 72.
COMMUNICATING SPACE TEMPERATURE SENSOR
(T-58) The communicating space temperature sensor (P/N
33ZCT58SPT) is wired to the Carrier Comfort Network®
(CCN) connections on TB202.
SPACE TEMPERATURE AVERAGING — Applications that
require averaging using multiple space temperature sensors can
be satisfied using either 4 or 9 sensors as shown in Fig. 73.
NOTE: Only Carrier sensors may be used for standard T-55
space averaging. Sensors must be used in multiples of 1, 4, and
9 only, with total sensors wiring not to exceed 1000 ft.
NOTE: Do not use T-56 sensors for space temperature averag-
ing because the 5-degree offset function will not work in a
multiple sensor application.
HEAT INTERLOCK RELAY (VAV Units Only — Not Neces-
sary for Digital Air Volume Applications) — Variable air vol-
ume (VAV) units using morning warm-up and/or occupied
heating require that room terminals be controlled to a position
that provides the minimum required heating cfm or greater
when the unit goes into Heating mode. The HIR (heat interlock
relay) function is provided for this control. When the unit goes
into Heating mode, the HIR is energized to provide switch clo-
sure or opening (depending on how the field-supplied power
source is set up) to open the room terminals. The field connec-
tions for the HIR are at TB201 terminals 9 and 10. See Fig. 74.
Option and Accessory Control Wiring — The P
Series units may be used in applications with additional control
features, options, or accessories. Refer to the Controls and
Troubleshooting manual for more information concerning
installation and configuration of options and accessories.

Carrier Comfort Network® (CCN) Interface —
The 48P Series units can be connected to the CCN system if
desired. The communication bus wiring is supplied and
installed in the field. It consists of shielded, 3-conductor cable
with shield wire.
The system elements are connected to the communication
bus in a daisy chain arrangement. The positive pin of each
system element communication connector must be wired to the
positive pins of the system element on either side of it, the
negative pins must be wired to the negative pins, and the signal
pins must be wired to common pins. Wiring connections for
the CCN system should be made at the terminal block using the
screw terminals. The board also contains an RJ14 CCN plug
that can be used to connect a field service computer. There is
also another RJ14 LEN (Local Equipment Network) connec-
tion that is used to download software or connect a Naviga-
tor™ device.
NOTE: Conductors and drain wire must be 20 AWG minimum
stranded, tinned copper. Individual conductors must be insu-
lated with PVC, PVC/nylon, vinyl, Teflon, or polyethylene. An
aluminum/polyester 100% foil shield and an outer jacket of
PVC, PVC/nylon, chrome vinyl, or Teflon with a minimum
operating temperature range of –4 to 140 F (–20 C to 60 C) is
required. See Table 28 for cables that meet the requirements.
Table 28 — CCN Connection Approved
Shielded Cables
The following color code is recommended:
NOTE: If a cable with a different color scheme is selected, a
similar color code should be adopted for the entire network.
At each system element, the shields of its communication
bus cables must be tied together. If the communication bus is
entirely within one building, the resulting continuous field
must be connected to a ground at one point only. If the commu-
nication bus cable exits from one building and enters another,
the shields must be connected to grounds at the lightning
suppressor in each building where the cable enters or exits the
building (one point per building only).
To connect the unit to the network (Fig. 84):
1. Turn off power to the control box.
2. Cut the CCN wire and strip the ends of the red (+), white
(common) and black (–) conductors. (If a different net-
work color scheme is used, substitute appropriate colors.)
3. Wire the CCN to the screw terminals on the COMM
board as follows (Fig. 84):
a. Secure the red (+) wire to CCN screw terminal +
on the COMM board.
b. Secure the white (common) wire to CCN screw
terminal C on the COMM board.

Optional UPC Open Installation
WIRING THE UPC OPEN TO THE MS/TP NET-
WORK The UPC Open controller communicates using
BACnet on an MS/TP network segment communications at
9600 bps, 19.2 kbps, 38.4 kbps, or 76.8 kbps.
Wire the controllers on an MS/TP network segment in a dai-
sy-chain configuration. Wire specifications for the cable are
22 AWG (American Wire Gage) or 24 AWG, low-capacitance,
twisted, stranded, shielded copper wire. The maximum length
is 2000 ft.
Install a BT485 terminator on the first and last controller on
a network segment to add bias and prevent signal distortions
due to echoing. See Fig. 85-87.
To wire the UPC Open controller to the BAS network:
1. Pull the screw terminal connector from the controller's
BAS Port.
2. Check the communications wiring for shorts and
grounds.
3. Connect the communications wiring to the BAS port’s
screw terminals labeled Net +, Net -, and Shield.
NOTE: Use the same polarity throughout the network
segment.
4. Insert the power screw terminal connector into the UPC
Open controller's power terminals if they are not current-
ly connected.
5. Verify communication with the network by viewing a
module status report. To perform a module status report
using the BACview keypad/display unit, press and hold
the “FN” key then press the “.” Key.
To install a BT485 terminator, push the BT485 on to the
BT485 connector located near the BACnet connector.
NOTE: The BT485 terminator has no polarity associated with
it.
To order a BT485 terminator, consult Commercial Products
i-Vu® Open Control System Master Prices.
MS/TP WIRING RECOMMENDATIONS — Recommen-
dations are shown in Tables 29 and 30. The wire jacket and UL
temperature rating specifications list two acceptable alterna-
tives. The Halar specification has a higher temperature rating
and a tougher outer jacket than the SmokeGard specification,
and it is appropriate for use in applications where the user is
concerned about abrasion. The Halar jacket is also less likely to
crack in extremely low temperatures.
NOTE: Use the specified type of wire and cable for maximum
signal integrity.
Smoke Control Modes — Rooftop units can be used
for aid in building smoke control in the event of a building fire.
The available functions include: Fire Shutdown, Pressuriza-
tion, Evacuation, and Smoke Purge. These functions are
enhanced when multiple rooftop units are used to zone a build-
ing. See Table 31 and Fig. 82 and 83.
FIRE SHUTDOWN Fire Shutdown mode terminates all
unit operation (cooling, heating, supply fan, and power
exhaust). This mode prevents recirculation of contaminated air
back into the space. The mode will not allow admission into
the space of unsuitable outside air. See Fig. 82 for wiring.
PRESSURIZATION — Pressurization mode is intended to
keep smoke out of a zone. The factory-installed optional econ-
omizer is required for this function. Pressurization is accom-
plished by the following:
opening the economizer (option)
running the supply fan (optional inlet guide vanes open
or optional VFD at normal duct static pressure set point)
closing the power exhaust dampers (if installed as option
or accessory)
shutting off the power exhaust fans (if installed as option
or accessory)
Table 29 — MS/TP Wiring Recommendations
LEGEND
IMPORTANT: A shorted CCN bus cable will prevent
some routines from running and may prevent unit from
starting. If abnormal conditions occur, unplug the connec-
tor. If conditions return to normal, check CCN connector,
and run new cable if necessary. A short in one section of
the bus can cause problems with all system elements on
the bus.

This allows the space to be overpressurized relative to adjacent
zones and prevents or slows entry of smoke into this space
from adjacent zones. See Fig. 82 for wiring.
EVACUATION Evacuation mode removes smoke or un-
desirable air from interior spaces without reintroducing unsuit-
able air. The factory-installed optional economizer with option/
accessory power exhaust is required for this function. Evacua-
tion is accomplished by the following:
turning the supply fan off
opening the economizer (option required)
running the exhaust fans (option or accessory required)
opening the exhaust dampers.

SMOKE PURGE — Smoke Purge mode removes smoke
from the interior spaces and replaces it with fresh outside air.
The factory-installed optional economizer with option/
accessory power exhaust are required for this function. Smoke
purge is accomplished by the following:
turning supply fan on
opening the economizer (option required)
running the exhaust fans (option or accessory required)
opening the exhaust dampers
See Fig. 82 for wiring.
SMOKE CONTROL INSTALLATION — Implementation of
the various smoke control modes on these units requires the in-
staller to modify the unit wiring to add contacts (via either
manual switches or relays) that will selectively interrupt and
override standard factory control sequences. See Table 31 and
Fig. 81 and 82 for more information.
