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 personnel.

When working on air-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.

INSTALLATION

Unit is shipped in the vertical discharge configuration. To

convert to horizontal configuration, remove screws from side

duct opening covers and remove covers. Using the same

screws, install covers on vertical duct openings with the insula-

tion side down. Seals around duct openings must be tight. See

Fig. 1.

Step 1 — Provide Unit Support

ROOF CURB — Assemble and install accessory roof curb in

accordance with instructions shipped with curb. See Fig. 2. In-

stall insulation, cant strips, roofing felt, and counter flashing as

shown. Ductwork must be attached to curb, not to the unit. The

accessory thru-the-bottom power and gas connection package

must be installed before the unit is set on the roof curb. If field-

installed (thru-the-roof curb) gas connections are desired, use

factory-supplied 3/4 in. pipe coupling and gas plate assembly to

mount the thru-the-roof curb connection to the roof curb. Gas

connections and power connections to the unit must be field in-

stalled 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 connec-

tions to the basepan in accordance with the accessory installa-

tion instructions.

Ensure voltage listed on unit data plate agrees with electri-

cal supply provided for the unit.

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 condition. 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 clos-

ing the gas valve.

Before performing service or maintenance operations on

unit, turn off main power switch to unit and install lockout

tag. Electrical shock could cause personal injury.

IMPORTANT: The gasketing of the unit to the roof curb

is critical for a watertight seal. Install gasket supplied

with the roof curb as shown in Fig. 2. Improperly

applied gasket can also result in air or water leaks and

poor unit performance.

48TJE,TJF004

48TJD,TJE,TJF005-007

Single-Package Rooftop Heating/Cooling Units

Curb should be level. Unit leveling tolerances are shown in

Fig. 3. This is necessary for unit drain to function properly. Re-

fer to Accessory Roof Curb Installation Instructions for addi-

tional information as required.

SLAB MOUNT (Horizontal Units Only) — Provide a level

concrete slab that extends a minimum of 6 in. beyond unit cab-

inet. Install a gravel apron in front of condenser coil air inlet to

prevent grass and foliage from obstructing airflow.

NOTE: Horizontal units may be installed on a roof curb if

required.

Step 2 — Field Fabricate Ductwork — Secure all

ducts to roof curb and building structure on vertical units. Do

not connect ductwork to unit. For horizontal applications, field-

supplied flanges should be attached to horizontal discharge

openings and all ductwork should be secured to the flanges. In-

sulate and weatherproof all external ductwork, joints, and roof

openings with counter flashing and mastic in accordance with

applicable codes.

Ducts passing through an unconditioned space must be in-

sulated and covered with a vapor barrier.

If a plenum return is used on a vertical unit, the return

should be ducted through the roof deck to comply with applica-

ble fire codes.

A minimum clearance is not required around ductwork.

Cabinet return air static shall not exceed –.30 in. wg with

EconoMi$er, or –.35 in. wg with Durablade Economizer, or

–.45 in. wg without economizer.

These units are designed for a minimum continuous return-

air temperature of 50 F (dry bulb), or an intermittent operation

down to 45 F (dry bulb) (in heating mode), such as when used

with a night set-back thermostat.

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

connections do not determine the use of drain connections;

either drain connection can be used with vertical or horizontal

applications.

When using the standard side drain connection, make sure

the plug (Red) in the alternate bottom connection is tight before

installing 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. See Fig. 4. The piping for

the condensate drain and external trap can be completed after

the unit is in place.

All units must have an external trap for condensate drain-

age. Install a trap at least 4-in. deep and protect against freeze-

up. If drain line is installed downstream from the external trap,

pitch the line away from the unit at 1 in. per 10 ft of run. Do not

use a pipe size smaller than the unit connection (3/4 in.).

Step 4 — Rig and Place Unit — Inspect unit for

transportation damage. File any claim with transportation

agency. Keep unit upright and do not drop. Spreader bars are

not required if top crating is left on unit. Rollers may be used to

move unit across a roof. Level by using unit frame as a refer-

ence. See Table 1 and Fig. 5 for additional information.

Lifting holes are provided in base rails as shown in Fig. 6.

Refer to rigging instructions on unit.

All panels must be in place when rigging and lifting.

POSITIONING — Maintain clearance around and above unit

to provide minimum distance from combustible materials,

proper airflow, and service access. See Fig. 6. A properly posi-

tioned unit will have the following clearances between unit and

roof curb: 1/4-in. clearance between roof curb and base rails on

each side and duct end of unit; 1/4-in. clearance between roof

curb and condenser coil end of unit. (See Fig. 2, section C-C.)

Do not install unit in an indoor location. Do not locate unit

air inlets within 10 ft of exhaust vents or other sources of con-

taminated air or as local codes require.

Be sure that unit is installed so 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 from

higher level runoff and overhangs.

Flue vent discharge must have a minimum horizontal clear-

ance of 4 ft from electric and gas meters, gas regulators, and

gas relief equipment.

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.

Adequate combustion-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 Standards Institute) Z223.1, and NFPA

(National Fire Protection Association) 54 TIA-54-84-1.

In Canada, installation must be in accordance with the

CAN1- B149 installation codes for gas burning appliances.

After unit is in position, remove rigging skids and shipping

materials.

Step 5 — Install Flue Hood — Flue hood is shipped

screwed to the burner compartment access panel. Remove

from shipping location and using screws provided, install flue

hood and screen in location shown in Fig. 7.

For units size 004-006 being installed in California Air

Quality Management Districts, which require NOx emissions

of 40 nanograms/joule or less, a field-installed low NOx kit

must be used.

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 en-

titled National Fuel Gas Code. In Canada, installation must be

in accordance with the CAN1.B149.1 and CAN1.B149.2 in-

stallation codes for gas burning appliances.

For natural gas applications, gas pressure at unit gas

connection must not be less than 4 in. wg or greater than

13.0 in. wg while unit is operating. On 48TJ005,006,007 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 sully piping for 0.5 in. wg maximum pressure drop.

Do not use supply pipe small than unit gas connection. Support

gas piping as shown in the table in Fig. 8. For example, a 3/4-in.

gas pipe must have one field-fabricated support beam every

8 ft. Therefore, an 18-ft 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.

Step 7 — Make Electrical Connections

DISCONNECT BOX LOCATION — The field-supplied dis-

connect box may be mounted on the unit’s end panel or on the

corner post. Mount disconnect box on the left side of the rating

plate when mounting on the unit’s end panel. Do not mount the

disconnect box over the unit rating plate. When mounting

disconnect box on corner post, secure disconnect box to corner

post and condenser coil top cover. See Fig. 7.

A disconnect box mounting space is available when an op-

tional or accessory condenser coil grille is used. Mount the dis-

connect on the sheet metal provided with the condenser coil

grille. The sheet metal is located adjacent to the corner post on

the left side of the power wiring access panel.

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-

ply, the transformer must be rewired by disconnecting the black

wire from the 230-v terminal wire on the transformer and con-

necting it to the 200-v red terminal of the transformer.

Refer to unit label diagram for additional information. Wir-

ing leads are provided for field service. Use copper conductors

only when splice connectors are used.

When installing units, provide a disconnect per NEC.

All field wiring must comply with NEC and local require-

ments. In Canada, electrical connections must be in accordance

with CSA (Canadian Standards Association) C22.1 Canadian

Electrical Code Part One.

Install field wiring as follows:

1. Connect ground lead to chassis ground connection when

using separate ground ties.

2. Install conduit between disconnect and side panel. Insert

conduit through power supply knockout opening. See

Fig. 9.

3. Connect power lines to power wiring leads.

4. Pigtails are provided for field power connections and are

located inside the burner access panel. See Fig. 10 and 11.

Use factory-supplied splices or Underwriters’ Laborato-

ries (UL) approved copper connector.

Unit cabinet must have an uninterrupted, unbroken electri-

cal ground to minimize the possibility of personal injury if

an electrical fault should occur. This ground may consist of

electrical wire connected to unit ground lug in control com-

partment, or conduit approved for electrical ground when

installed 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.

NOTES:

1. Dimension in ( ) is in millimeters.

2. Hook rigging shackles through holes in base rail, as shown in

detail ‘‘A.’’ Holes in base rails are centered around the unit cen-

ter of gravity. Use wooden top skid when rigging to prevent rig-

ging straps from damaging unit.

3. Unit weights do not include economizer. See Table 1 for econo-

mizer weights.

All panels must be in place when rigging.

Voltage to compressor terminals during operation must be

within voltage range indicated on unit nameplate (see Table 2).

On 3-phase units, voltages between phases must be balanced

within 2% and the current within 10%. Use the formula shown

in the legend for Table 2, Note 2 to determine the percent of

voltage imbalance. Operation on improper line voltage or ex-

cessive phase imbalance constitutes abuse and may cause dam-

age to electrical components. Such operation would invalidate

any applicable Carrier warranty.

FIELD CONTROL WIRING — Install a Carrier-approved

accessory thermostat assembly according to installation in-

structions included with the accessory. Locate thermostat

assembly on a solid wall in the conditioned space to sense aver-

age temperature in accordance with thermostat installation

instructions. 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. 12).

NOTE: For wire runs up to 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 ft, 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 at the

thermostat.

Feed control wires through the raceway located between the

condenser coil top cover and burner side panel. See Fig. 10.

Connect control wires to corresponding screw terminals, the

low-voltage connections located inside low-voltage access

panel. See Fig. 12 for connections. The low-voltage connec-

tions provide the UL required clearance between high- and

low-voltage wiring.

HEAT ANTICIPATOR SETTINGS — Set heat anticipator

settings at .14 amp for the first stage and .14 amp for second-

stage heating, when available.

NOTES:

1. In compliance with NEC requirements for multimotor and combination

load equipment (refer to NEC Articles 430 and 440), the overcurrent

protective device for the unit shall be fuse or HACR breaker. Canadian

units may be fuse or circuit breaker.

2. Unbalanced 3-Phase Supply Voltage

Never operate a motor where a phase imbalance in supply voltage is

greater than 2%. Use the following formula to determine the percent

of voltage imbalance.

% Voltage Imbalance

Example: Supply voltage is 460-3-60.

AB = 452 v

BC = 464 v

AC = 455 v

= 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 of voltage imbalance.

= 1.53%

This amount of phase imbalance is satisfactory as it is below the max-

imum allowable 2%.

temperature at which you want the mechanical cooling (com-

pressors) to be disabled. Locate the mechanical cooling lock-

out (MECH CLG LOCKOUT) potentiometer. To disable this

feature, turn the potentiometer counterclockwise (CCW) to the

OFF position. Otherwise, set the value between 10 and 60 F.

Mechanical cooling will not operate when the outdoor air tem-

perature is below this value. See Fig. 38.

Dry Bulb Changeover Set Up — Determine the dry bulb

changeover set point from Table 3. The settings are A, B, C

and D. Locate the ECON SP potentiometer and set the dry

bulb changeover set point. See Fig. 38. When the OAT is

above this set point, the damper is limited to minimum position

setting.

Table 3 — Changeover Set Points

*Field-installed accessory.

If a potentiometer fails, its setting will default to the values in

Table 4.

Table 4 — Default Potentiometer Settings

Ventilation Air (Minimum Position Set up) — If ventilation

air is not required, proceed to Step 5. If ventilation air is

required, perform the following:

1. The indoor fan must be on to set the ventilation air. Either

put the thermostat in the continuous fan mode or jumper

the R and G terminals at the rooftop unit connection

board.

2. Locate the minimum position (MIN POS) potentiometer.

Turn the potentiometer full CCW to fully close the out-

door air dampers. Turn the potentiometer gradually

clockwise (CW) to the desired position. See Fig. 38.

3. Replace the filter access panel. See Fig. 26. Ensure the fil-

ter access panel slides along the tracks and is securely

engaged.

4. Calculate the minimum airflow across the EconoMi$er.

a. Calculate % of outside air using the following

formula.

% Outdoor air through EconoMi$er

b. Divide total CFM by percentage outdoor air, this

gives outdoor air volume in CFM.

5. Turn on base unit power.

NOTE: The EconoMi$er begins operation three min-

utes after power up.

6. See Fig. 39 for barometric relief damper characteristics.

Step 9 — Adjust Evaporator-Fan Speed — Ad-

just evaporator-fan rpm to meet jobsite conditions. Table 5

shows fan rpm at motor pulley settings. Table 6 shows motor

performance. See Table 7 for Accessory/FIOP Static Pressure.

Refer to Tables 8-29 to determine fan speed settings.

DIRECT-DRIVE MOTORS — The evaporator-fan motor

factory speed setting is shown on label diagram affixed to base

unit. If other than factory setting is desired, refer to label dia-

gram for motor reconnection. See Fig. 40 for direct drive motor

location.

BELT-DRIVE MOTORS — Fan motor pulleys are factory set

for speed shown in Table 1. See Fig. 41 for belt drive location.

NOTE: Before adjusting fan speed, make sure the new fan

speed will provide an air temperature rise range as shown in

Table 1.

To change fan speed:

1. Shut off unit power supply and tag disconnect.

2. Loosen belt by loosening fan motor mounting nuts. See

Fig. 41.

3. Loosen movable pulley flange setscrew (see Fig. 42).

4. Screw movable flange toward fixed flange to increase

speed and away from fixed flange to decrease speed.

Increasing fan speed increases load on motor. Do not ex-

ceed maximum speed specified in Table 1.

5. Set movable flange at nearest keyway of pulley hub and

tighten setscrew. (See Table 1 for speed change for each

full turn of pulley flange.)

To align fan and motor pulleys:

1. Loosen fan pulley setscrews.

2. Slide fan pulley along fan shaft.

3. Make angular alignment by loosening motor from

mounting.

To adjust belt tension:

1. Loosen fan motor mounting nuts.

2. Slide motor mounting plate away from fan scroll for

proper belt tension (1/2-in. deflection with 8 to 10 lbs of

force).

3. Tighten motor mounting nuts.

4. Adjust bolt and tighten nut to secure motor in fixed

position.
