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.

Catalog No. 04-53480014-01 Printed in U.S.A, Form 48T-5SI Pg 1 9-05 Replaces: 48T-3SI

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.

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- age. Instull a tru l) at least 4-in. deep and prowct against fi'eeze- Ul).I/ drain line is installed downstmam /?om the exWrlml trap,

pitch the fine awayfl'om the unit at 1 in. per lOft q/run. Do not

use a pipe s£e smaller than the unit connection (J/4 in.).

Do not install unit in an indoor location. Do not locate unit air inlets near exhaust vents or other sources of contalninated all:

Be sure that unit is installed such that snow will not block the combustion intake or flue outlet.

Unit may be installed directly on wood flooring or on Class A, B, or C roof-covering material when roof curb is used.

Although unit is weatherproof, guard against water fiom

higher level runoff and overhangs.

Flue vent dischaqq, e must have a minimum hoH;ontul clear- ance qf4 fi,fmm elecTHc and gas mewrs, gas mgulawt:_, and

gas milerequipment.

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.

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.

Outdoor Air Enthalpy Sensor/Enthalpy Controller (HH57AC077) i To wile the outdoor air enthalpy sensoit

perform the following (see Fig. 18 and 19): NOTE: The outdoor air sensor can be removed from die back

of die enthalpy controller and mounted remotely.

1. Use a 4-conductor. 18 or 20 AWG cable to connect the enthalpy control to the PlemierLink controller and power

transforme_:

2. Connect the following 4 wires from the wire harness located in rooftop unit to the enth_dpy controller:

a. Connect the BRN wire to the 24 vac terminal (TRI)

on enthalpy control and to pin 1 on 12-pin harness.

b. Connect the RED wire to the 24 vac GND terminal

(TR) on enthalpy sensor and to pin 4 on 12-pin harness.

c. Connect the GRAY/ORN wire to J4-2 on Premier-

Link controller and to terminal (3) on enthalpy sensoE

d. Connect the GRAY/RED wire to J4-1 on Premier-

Link controller and to terminal (2) on enthalpy sensol:

NOTE: If installing in a Carrier roollop, use the two gray wires provided from the control section to the economizer to connect PremierLink controller to termimds 2 and 3 on enthalpy sensol:

Return Air Enthalpy Sensor i Mount the return-air enth_dpy sensor (HH57AC078) in the return-air duct. The return air sensor is wired to the enthalpy controller (HH57AC077). The outdoor enthalpy changeover set point is set at the controllel:

To wire the return air enthalpy sensor, perform the follow-

ing (see Fig. 18):

1. Use a 2-conductor, 18 or 20 AWC_ twisted pair cable to connect the return air enthalpy sensor to the enthalpy

controller.

2. At the enthalpy control remove the factory-installed resistor from the (SR) and (+) terminals.

3. Connect the field-supplied RED wire to (+) spade connector on the return air enth_dpy sensor and the (SR+) terminal on die enthalpy controller Connect the BLK wire to (S) spade connector on the return air enth_dpy sensor and the (SR) termimd on die enthalpy controlle_:
