START-UP CHECKLIST ........................ CL-I

Untrained personnel can perform basic maintenance func- tions of cleaning coils and filters and replacing filtet.s. 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 may apply.

Follow all safety codes. 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 and install lockout tag. Ensute voltage listed on unit information plate agrees with electrical supply to rite unit. Electrical shock could cause serious personal injury.

INSTALLATION

Unit is shipped in the vertical configuration. To convert to hotizont_dconfiguration, remove side duct opening covers. Us- ing the same screws, install covers on vertical duct openings with the insulation-side down. Seals around duct openings must be tight.

Step 1 -- Provide Unit Support

ROOF CURB -- Assemble and inst_dlthe accessoty roof curb in accordance with instructions shipped with the curb. See Fig. 1. Install insulation, cant strips, roofing felt, and counter

flashing as shown. Ductwork must be attached to the curb. If electric or control power is to be routed through the basepan,

attach the accessory thru-the-bottom service connections to the basepan in accor&mce with the accessory installation instruc-

tions. Connections must be installed before the unit is set on roof curb.

SAFETY CONSIDERATIONS

Installation and servicing of air-conditioning equipment can

be hazardous due to system pressure and electtic_d compo- nents. Only trained and qualified service personnel should

install, repair, or service ai>conditioning equipment.

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

also result in air leaks and poor unit performance.

The roof curb should be level. Unit leveling tolerances am

shown in Fig. 2. This is necessmy for unit drain to function properly. Refer to Accessory Roof Curb Installation Instruc-

tions for additional information, as required. SLAB MOUNT (Horizontal Units Only) -- Provide a level

concrete slab that extends a minimum of 6 in. beyond file unit's cabinet. Inst_fll a gravel apron in front of the condenser coil air

inlet to prevent grass and foliage from obstructing airflow. NOTE: Horizontal units may be installed on a roof curb if

required. ALTERNATE UNIT SUPPORT -- When the curb or adapter

cannot be used, support unit with sleepers using unit curb or a&Tter support area. If sleepers 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 -- On vertic;d

discharge units, secure all ducts to the roof curb and building structure. Do not connect ductwork to the unit. For horizontal

applications, field-supplied flanges should be attached to hori- zontal discharge openings and all ductwork attached 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 in-

sulated and covered with a vapor barriel:

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 pressure (a negative condition) should not exceed 0.35 in. wg with economizer, or 0.45 in. wg without

economizer.

Step 3 -- Install Condensate Drain Line and External Trap -- Condensate di'ain connections ;ue

located at the bottom and end of the unit. Unit discharge connections do not determine the use of drain connections; use

either drain connection in vertic_d or horizontal applications.

When using the standmd end diain connection, make sure

the plug (Red) in the _dternate 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 end connection. Tile center di'ain plug looks

like a star connection, but can be removed with a I/2 in. socket drive extension. See Fig. 3. The piping for the condensate di'ain

and external trap can be completed after the unit is in place.

All units must have an extern_fl trap for condensate di'ain- age. [nstall a trap at least 4-in. deep and protect it against freeze-up. If the drain line is installed downstream from the ex- tern_d 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

(314in.). See Fig. 4. Step 4 -- Rig and Place Unit --Inspect the unit for

transportation damage. File any claim with the transportation agency. Keep the unit upright and do not diop. Spreader bars are not required if top crating is left on the unit. Rollers may be used to move the unit across a roof. Level by using the unit frame as a reference. See Table 1 and Fig. 5 for additional information. Operating weight is shown in Table 1 and Fig. 5.

Lifting holes are provided in the base rails as shown in

Fig. 5 and 6. Refer to the rigging instructions on file unit. POSITIONING --Maintain clearance m'ound and above the

unit to provide proper airflow and service access. See Fig. 6.

Position the unit on the roof curb so that the following

clearances are maintained: %-in. clearance between roof curb and base rails on each side and in duct end of unit;

3s/16-in. clearance between the roof curb and outdoor coil

end of the unit (see Fig. 1, section C-C).

Do not install the unit indoor._. Do not locate the unit's air inlet near exhaust vents or other soumes of contaminated all:

Although the unit is weatherproof, gumd against water from higher level runoff and overhangs.

After the unit is in position, remove the polyethylene ship-

ping wrapper and rigging skid.

Step 5 -- Make Electrical Connections

Unit cabinet must have an uninterrupted, unbroken electri- cal ground to minimize the possibility of personal inju U if an electrical fault should occm_ 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 actor&race with NEC (National Electrical Code) ANSI (American Nation_d Standiu_ds Institute)/ NFPA (Natiomd Fire Protection Association) 70 latest revi-

sion and local electric_d codes. Failure to follow this warn- ing could result in the installer being liable for persomd

inju U of others.

FIELD POWER SUPPLY -- All units except 208/230-v units are factory-wired for the voltage shown on the unit nameplate. If the 208/230-v unit will be connected to a 208-v power sup- ply, the transformer must be rewired by disconnecting the

black wire fiom the 230-v l/4-in, male spade temrinal on the transformer and connecting it to the 200-v l/4-in, m_de spade

terminal fiom the transformel_

Refer to the unit label diagram for additional infommtion.

Pigtails are provided for field wire connections. Use facto U-

supplied splices or a UL (Underwriters' Laboratories) ap- proved copper/aluminum connectol:

When inst_dling units, provide a disconnect per the NEC. All field wiring must comply with the NEC and local re-

quirements. In Canada, electrical connections must be made in accor&mce with CSA (Canadian Stan&_rds Association) C22.1 Canadian Electric_d Code Part One.

Inst_dl field wiring as follows:

1. Inst_dl conduit through the unit's side panel openings. For units without electric heat, install conduit between the

disconnect and control box.

2. Inst_dl power lines to terminal connections as shown in Fig. 7.

3. For units with electric heat, refer to Table 2 and Accessory Installation Instructions.

During operation, voltage to compressor terminals must

be within the range indicated on the unit nameplate (see Tables 3A-3D). On 3-phase units, voltages between phases

must be balanced within 2%, and the current within 10%. Use the formula shown in Tables 3A-3D, Note 2 on page 11 to

determine the percentage of voltage imbalance. Operation on

iml)rOl)er line voltage or (_rcessive phase imbalance constitutes abuse and may cause damage to electrical components. Such

ol)eration invalidaws an)" applicable Carrier warrant).'.

*Two heater packages required to provide kW indicated. NOTES:

1. The rated heater voltage is 240 and 480 v. If power distribution voltage varies from rated heater voltage, heater kW will vary accordingly.

2. To determine heater kW at voltages other than those shown in table, use the following formula: Heater kWnew= Heater kW rated x (unit power distribution voltage/rated heater voltage) 2

As an example:

HELD CONTROL WIRING -- Install a Carrier-approved accessory thennostat assembly according to the installation

instructions included with the accessory. Locate file thermostat assembly on a solid wall in the conditioned space to sense average temperature in accor&mce with thermostat installa-

tion instructions. NOTE: If using a Carrier electronic thermostat, set the thenno-

star configuration for "non-heat pump operation." This family of products does not require an O temfinal to energize the

reversing valve.

Route the thermostat cable or equivalent single leads of col- ored wire from the subbase termimds to the low-voltage con- nections on the unit (shown in Fig. 8A and 8B) as described in Steps 1 fllrough 4 below.

NOTE: For wire runs up to 50 ft, use no. 18 AWG (American

Wire Gage) insukited wire (35 C minimum). For 51 to 75 1l, use

no. 16 AWG insukited wire (35 C minimum). For over 75 fi, use no. 14 AWG insukited wire (35 C minimum). All wire larger than no. 18 AWG cannot be directly connected to the thermostat and will require ajunction box and splice at the thermostat.

1. If the unit is mounted on the roof curb and an accessory thin-the-curb service plate connection is used, route the

wire through connection plate.

2. Pass control wires through the hole provided on the unit (see connection D in the Connection Sizes table in

Fig. 6).

3. Feed wire through the raceway built into the comer post to the 24-v bmrier located on the left side of the control box.

See Fig. 9. The raceway provides the UL lequiled clear- ance between the high-voltage and low-voltage wiring.

PREMIERLINK TM CONTROL -- The PmmierLink control- let is compatible with Career Comfort Network® (CCN)

devices. This control is designed to allow users the access and ability to change factory-defined settings, thus expanding the function of file standiu'd unit control board. Career's diagnostic

standard tier display tools such as Navigator TM or Scrolling Marquee can be used with the PremierLink controller.

The PremielLink controller (see Fig. 15A and 15B) requires

the use of a Carrier electronic thermostat or a CCN connection for time broadcast to initiate its intermfl fimeclock. This is

necessary 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 (OAT) as standard. An indoor air quality (CO2) sensor can be added as an option. Refer to Table 5 for

sensor usage. Refer to Fig. 16 for PmmierLink controller wir- ing. The PremierLink 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 thermostat, the PmmierLink controller must be configured to Themlostat

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 wired. The wiring is routed from file 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 file flange of

the supply-air opening or in file supply air duct (as lequimd by loc_fl codes). Drill or punch a 1/2-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 airstmam downstream of file cooling coil and any heating devices. Be

sum the probe tip does not come in contact wifll any of the unit or heat surfaces.

Outdoor Air Temperature Sensor (OAT) -- When the unit is supplied with a factory-mounted PremierLink control, the

outdoor-_dr temperature sensor (OAT) is factory-supplied and wimdi

Install the Indoor Air Quality (CO_ Sensor -- Mount the optional indoor air quality (Ci2)2) sensor according to manufac- turer specifications.

A separate field-supplied transformer must be used to pow-

er the CO2 sensor:

Wile the CO2 sensor to the COM and IAQI terminals of J5

on the PremierLink controllec Refer to the PremierLink Instal- lation, Start-up, and Configuration Instructions for detailed

wiring and configuration information.
