GENERAL

This installation instruction contains basic unit installation

information, including installation of thermostats and remote

temperature sensors.

For additional information and service instructions, refer to

the Controls and Troubleshooting literature also enclosed in

this literature packet.

The 48ZT, ZW units are equipped with standard integral

economizer and high-capacity power exhaust.

The 48Z6,Z8 units are equipped with factory-installed

return!exhaust fans.

The staged gas control (SGC) option adds the capability to

control the rooftop unit's gas heating system to a specified sup-

ply air temperature set point for purposes of tempering a cool

mixed-air condition.

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.

Before performing service or maintenance operations on

unit, turn off main power switch to unit. Electrical shock

could cause personal iniury.

Do not try to light any appliance. Do not touch any electri-

cal switch; do not use any phone in your building. Ilmnedi-

ately call your gas supplier from a neighbor's phone.

Follow the gas supplier's instructions. If you cannot reach

your gas supplier, call the fire department.

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.

Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.

Catalog No. 04-53480044-O1 Printed in U.S.A. Form 48Z-7SI Pg 1 6-08 Replaces: 48Z-4SI

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.

INSTALLATION

Jobsite Survey EComplete 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.

Do not lift unit with forklift truck. Move unit with over-

head rigging only.

Curb Gasketing

SIZE 030-050 UNITS -- After ductwork has been connected

to the roof curb, attach adhesive-backed gasketmg 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 055-105 UNITS -- After ductwork has been connected

to the roof curb, apply gasket material (1/:-in. thick x ll/:-in.

wide neoprene) where indicated.

Single-Thickness Gasketing (See Fig 6-8 for Item Num-

bersl -- 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 with 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).

Field-Fabricated Ductwork

Unit Placement EInspect unit for transportation dam-

age. 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.

Check unit dimensional drawings for unit arrangement and

lnmimum 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.

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 between the exhaust hood and any obstruc-

tion. 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-6.

Roof Mount _Check building codes for weight distribu-

tion requirements. Unit weight is shown in Tables 1A-1C and

2. 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 dram to function

properly, curb must be level or within tolerances shown m

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.

Slab Mount _Provide a level concrete slab that extends

beyond unit cabinet at least 6 inches. Make a slab 8 in. thick

with 4 in. above grade. Use gravel apron m front of condenser

coil air inlet to prevent grass and foliage from obstructing

airflow. Ensure that slab is of sufficient height to allow for con-

densate trap of 4 in. on sizes 030-070 or 7 m. on sizes 075-105.

For vertical supply and return units, tools or parts could

drop into ductwork and cause an injury. Install a 90-degree

turn 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.

The 48ZG, ZN, ZT, ZW, Z6,Z8 units are designed for vertical

supply/return only. Field-fabricated ductwork must be attached

to the roof curb, on to the support steel, prior to the final rigging

and installation of the unit. Supply and return duct dhnensions

are shown in Fig. 1-3.

To attach ductwork to roof curb, insert duct approximately 10

to 11 m. 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. The return duct must have a 90-degree

elbow before opening into the building space if the unit is

equipped with power exhaust.

Design supply duct strong enough to handle expected static

pressures.

Rigging _Do not drop unit; keep upright. Use spreader

bars over unit to prevent sling or cable damage. Sheets of ply-

wood placed along the condenser coils will provide additional

protection. All lifting lugs MUST be used when lifting unit.

Level by using unit frame as a reference. See Fig. 9-13 for m-

formation. Unit and accessory weights are shown in Tables 1A-

1C and 2. Weight distribution and center of gravity can be

found in Fig. 14.

Fig. 14 -- Weight Distribution and Center of Gravity

Condensate Drain Connections -- There are a to-

tal of five dram connections required on each unit: one primary

dram (on right-hand side of the unit) and four secondary drains

(two on each side of unit).

PRIMARY DRAIN -- The primary drain is a 2-in. NPT pipe

connection located on the right-hand side of the unit looking at

the unit from the return air end. See Fig. 15-24.

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-m. for size 075-105 units. See Fig. 24 and 25. 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 sfinilar sealant around the pipe joint at the con-

nector in the base rail.

SECONDARY DRAINS (Units Installed on

Curb) -- There are two secondary dram connections on each

side of the unit. See Fig. 26. There are secondary drains on

each side of the unit in the filter section and one on each side of

the unit in the supply fan section. There are labels marking

each location on the unit base rail. See Fig. 15-23.

Locate the four P/4-m. 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 11/4in. half coupling welded to the plate.

At each secondary drain hole location, there is a 13/s-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. 27. Do not attach any dram 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. 28. Provide a

mmilnum size of ½-in. pipe for secondary drams. Use a trap at

least 4-m. deep for size 030-070 units and 7-in. deep for size

075-105 units. Apply a bead of RTV or similar sealant around

the dram assemblies.

Consult local plumbing codes for direction onjoining multi-

ple dram lines. Total size of any combined line does not need

to exceed nominal 2-m. size of primary dram 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 dram connections required

on each side of the unit. See Fig. 26. There are secondary

drams on each side of the unit in the filter section and one on

each side of the unit m the supply fan section. There are labels

marking each location on the unit base rail. See Fig. 15-23. Pri-

or to final positioning of the unit, apply a bead of RTV or simi-

lar sealant around each secondary drain hole in the bottom of

the unit base rail. Then position the unit into final location.

Locate the four 11/4-m. 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 m. 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/s-in. hole saw) and for

the mounting screws (use 3/j6-in. drill bit).

3. Install a dram 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. 28. Pro-

vide lnimmum size of ½-m. pipe for secondary drains.

Use a trap at least 4-in. deep for size 030-070 units and

7-in. deep for size 075-105 units.

5. Apply a bead of RTV or similar sealant around the drain

assemblies.

Consult local plumbing codes for direction onjoining multi-

ple drain lines. Total size of any combined line does not need

to exceed nominal 2-in. size of primary dram 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.

Field Wire Routing

UNIT SIZES 030-050 -- 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. NPT coupling for field power and a 3/4-in. NPT

coupling for 24 v control wiring are provided in the basepan.

There are two 45/8-in. knockouts 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 45/8-in. knockouts to the field-

supplied disconnect and then back into the unit through the oth-

er knockout. See Fig. 39 for recolrnnended disconnect location.

If power wiring is brought through the side of the unit, route

wiring from field-supplied disconnect through top 45/s-in.

knockouts into unit.

If control wiring is to be brought in through the side of the

unit, a 7/s-in. diameter hole must be drilled in the corner post

next to the control box.

UNIT SIZES 055-105 -- 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 and 41.

A 45/32-in. hole for field power wiring and a 7/s-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 and 41 for recolmnended disconnect location.

Field Electrical Connections

IMPORTANT: The 48ZN,ZW, Z8 units generate, use,

and can radiate radio frequency energy. If units are not

installed and used in accordance with these instructions,

they may cause radio interference. They have been

tested and found to comply with limits of a Class A

computing device as defined by FCC (Federal Cogunu-

nications Colrnnission) regulations, Subpart J of Part 15,

which are designed to provide reasonable protection

against such interference when operated in a cogunercial

enviromnent.

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 [Maxhnum Overcurrent Pro-

tection] 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. 42 for power wiring connections to the unit power ter-

minal 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 a separate control

box behind the control box door for all units. See Fig. 43.

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. 44 for power wiring con-

nections to the unit disconnect and equipment ground.

DISCONNECT SIZE QUANTITY...MAXIMUM WIRE SIZE

(MCM)

200 Amps 1 ,,,300

400 Amps 1 ,,,600

600 Amps 2,,,600

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 7-16

for unit electrical data.

Use the following formula to determine the percentage of

voltage imbalance.

Voltage hnbalance

= 100 x max voltage deviation from average voltage

average voltage

Example: Supply voltage is 460-3-60.

A B C AB = 452 v

BC = 464 v

AC = 455 v

Average Voltage = 455 + 464 + 455

1371

= 457

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 hnbalance:

% Voltage Imbalance = 100 x 45----5-

= 1.53%

This amount of phase imbalance is satisfactory as it is be-

low the maximum allowable 2%.

I IMPORTANT: If the supply voltage phase hnbalance is I

more than 2%, contact local utility ilmnediately. I

Unit failure as a result of operation on hnproper line voltage

or excessive phase imbalance constitutes abuse and may cause

damage to electrical components.

LIST_O

Air Pressure Tubing- Before options such as inlet

guide vanes (IGV), variable frequency drive (VFD), and/or

modulating power exhaust can operate properly, the pneumatic

robing for pressure sensing must be installed. Use fire-retardant

plenum robing (field-supplied). All control devices use V4-in.

robing. Tubing must be mn from the appropriate sensing loca-

tion (in the duct or in the building space) to the control device

location in the unit.

INLET GUIDE VANES -- The tubing for the duct pressure

(DP) control option should sample supply duct pressure about

2/3 of the way out from the unit in the main trunk duct, at a

location where a constant duct pressure is desired.

The duct pressure is sensed by a pressure transducer. The

output of the pressure transducer is directed to the unit control

module. On all sizes, the DP transducer is located in the unit

auxiliary control box. See Fig. 45 and 46 for auxiliary control

box location. See Fig. 47 and 48 for auxiliary control box

details. Use a nominal a/4-in, plastic robing.

VARIABLE FREQUENCY DRIVE -- The robing for the

duct pressure (DP) control option should sample supply duct

pressure about 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. 45 and 46 for auxiliary

control box location. See Fig. 47 and 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. 45 and 46 for auxiliary control box location.

See Fig. 47 and 48 for auxiliary control box details. Use a nom-

inal 1/4-m. plastic tubing.

For instructions on adjusting BP control set points, refer to

the Controls and Troubleshooting book.

RETURN/EXHAUST POWER EXHAUST -- The tubing

for the building pressure (BP) control (achieved via the return!

exhaust power exhaust option) should sample building pres-

sure in the area near the entrance lobby (or other appropriate

and sensitive location) so that location is controlled as closely

to design pressures 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. 46 for auxiliary control box location. Fig. 49

for auxiliary control box details. Use a nominal 1/4-in. plastic

robing.

For instructions on adjusting BP control set points, refer to

the Controls and Troubleshooting book.

Compressor Mounting

SIZES 030-090 -- Each compressor is supported on

4 springs. The springs are compressed for shipment. After the

unit is installed, the holddown nuts need to be loosened for nor-

mal operation. See Fig. 55 for compressor mounting details.

Loosen each bolt using nut indicated until the flatwasher

(3/s-in.) can be moved with finger pressure. Do not remove the

locknuts. Check each compressor mounting to ensure all 4

springs have been loosened properly.

SIZE 105- Compressors are mounted on rails and held

down by rail bolts during shipment. After unit is installed, loos-

en the rail bolts to allow the rails and compressors to float free-

ly on the springs located under the rails. See Fig. 56 and 57.

Gas Piping -- Unit is equipped for use with natural gas

only. Installation must conform with local building codes, or in

the absence of local codes, with the National Fuel Gas Code

(NFGC), ANSI Z223.1.

A 1&-in. NPT tapping plug, accessible for test gage connec-

tion, must be field installed hmnediately upstream of gas sup-

ply connection to unit, but after manual gas valve. See Fig. 58.

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.

Disconnect gas piping from unit 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 con-

dition. If gas valve is subjected to pressure greater than

0.5 psig, it must be replaced.

Optional Staged Gas Control -- The 48Z030-105

large rooftop units may be ordered with an optional factory-

installed staged gas control system that monitors heating opera-

tion of the rooftop. The control system is composed of several

components as listed in sections below. Table 17 shows 48Z

Series staged gas implementation.

Refer to the Unit Controls and Troubleshooting book for in-

formation on configuring staged gas control.

control, and an output for fan control. The thermostat may also

include time of day scheduling or use scheduling routines built

into the (_mfortLink TM 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 TB203

connections, see Fig. 67.

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. 18AWG cannot be directly connected at the thermostat

and will require a junction box and splice at the thermostat.

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.

NOTE: Humidity and CO2 sensors must be powered from

isolated 24-v power supplies.

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) is shipped standard with

every unit, and is located in the main control box. Space tem-

perature sensor wires are to be connected to terminals in the

unit main control box.

Jumper MUST be in place between pins 1 and 3, 3 and 4

or inaccurate readings could result.

To connect the space temperature sensor, see Fig. 68.

SPACE TEMPERATURE SENSOR (T-56) -- The space tem-

perature sensor (P/N 33ZCT56SPT) wires are connected to

terminals in the unit main control box.

Jumper MUST be in place between pins 1 and 3, 3 and 4

or inaccurate readings could result.

To connect the space temperature sensor, see Fig. 68.

COMMUNICATING SPACE TEMPERATURE SENSOR

(T-58)--The colmnunicating space temperature sensor (P/N

33ZCT58SPT) is wired to the Carrier Comfort Network _-R:

(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. 69.

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. How-

ever, space temperature reset can be accomplished with only

one sensor.

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 (VAVUnits Only -- Not Neces-

salTFor Digital Air Volume Applications) -- Variable air vol-

ume (VAV) units using opthnal start (morning warm-up) and/

or occupied heating require that room terminals be controlled

to the fully open position 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 closure or opening (depending on

how the field-supplied power source is set up) to open the room

terminals. The field connections for the HIR are at TB201 ter-

minals 7 and 8. See Fig. 70.

Option and Accessory Control Wiring -- The Z

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.

Figures 70-80 contain wiring information on the following

features:

• Heat interlock relay (Fig. 70)

• Outdoor air enthalpy switch (Fig. 71)

• CO2 space sensor (Fig. 72)

• Filter status switch (Fig. 73)

• Fan status switch (Fig. 74)

• Space humidity sensor (Fig. 75)

• Return air humidity sensor (Fig. 75)

• Return air CO2 sensor (Fig. 76)

• Return air smoke detector (Fig. 77)

• Smoke control -- fire shutdown (Fig. 78)

• Smoke control- purge (Fig. 79)

• Smoke control -- evacuation (Fig. 79)

• Smoke control -- pressurization (Fig. 79)

• CCN connections (Fig. 80)

Carrier Comfort Network (CCN) Interface -- The

48ZN,ZW,Z8 units can be connected to the CCN system if de-

sired. The colmnunication 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 colmnunicafion

bus in a daisy chain arrangement. The positive pin of each

system element COlrnnunication 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 signal ground 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 Navigator TM device or field

service computer. There is also another RJ14 LEN (Local

Equipment Network) connection that is used to download soft-

ware. Consult CCN Contractor's Manual for further

information.

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 20 for cables that meet the requirements.

IMPORTANT: When connecting the CCN colrnnunica-

tion bus to a system element, use a color coding system for

the entire network to simplify installation and checkout.

The following color code is recolrnnended:

SIGNAL CCN BUS CONDUCTOR COMM1 PLUG

TYPE INSULATION COLOR PIN NO.

+ RED 1

GROUND WHITE 2

- BLACK 3

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 colmnunication

bus cables must be tied together. If the colmnunication bus is

entirely within one building, the resulting continuous field

must be connected to a ground at one point only. If the colmnu-

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. 80):

1. Turn offpower to the control box.

2. Cut the CCN wire and strip the ends of the red (+), white

(ground) and black (-) conductors. (Ira different network

color scheme is used, substitute appropriate colors.)

3. Wire the CCN to the screw terminals on the COMM

board as follows (Fig. 80):

a. Secure the red (+) wire to CCN screw terminal +

on the COMM board.

b. Secure the white (ground) wire to CCN screw

terminal C on the COMM board.

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 21 and Fig. 78 and 79.

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. 78 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 offthe power exhaust fans (if installed as option

or accessory)

This allows the space to be overpressurized relative to adja-

cent zones and prevents or slows entry of smoke into this space

from adjacent zones. See Fig. 79 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.

See Fig. 79 for wiring.

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. 79 for wiring.

SMOKE CONTROL INSTALLATION -- hnplementation 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

ovemde standard factory control sequences. See Table 21 and

Fig. 78 and 79 for more information.
