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.

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.

Determine the EconoMiSer IV control mode before set up of

file control. Some modes of operation may require different sen- sors. Refer to Table 5. The EconoMiSer IV is supplied from the

facto q with a supply air temperature sensor and an outdoor air temperature sensol: This allows for operation of the EconoMiSer IV with outdoor air dry bulb changeover control.

Additional accessories can be added to allow for different types of changeover control and operation of the EconoMiSer IV and unit.

Outdoor DLy Bulb Changeover -- The standard controller is shipped from the facto q configured for outdoor @ bulb

changeover control. The outdoor air and supply air temperature sensors me included as standmd. For this control mode, the outdoor temperature is compared to an adjustable set point

selected on file control. If the outdoor-air temperature is above file set point, file EconoMiSer IV will adjust the outdoor-air

dampers to minimum position. If the outdoor-air temperature is below the set point, the position of the outdoor-air &tmpers will

be controlled to provide flee cooling using outdoor till: When in this mode, the LED next to the free cooling set point potenti-

ometer will be on. The changeover temperature set point is controlled by the free cooling set point potentiometer located

on the control. See Fig. 33. The sc_de on the potentiometer is A, B, C, and D. See Fig. 34 for the corresponding temperature

changeover values.

Differential DLy Bulb Control -- For differential dly bulb control the stan&ud outdoor dry bulb sensor is used in conjunc-

tion with an additional accesso U ch7 bulb sensor (part number CRTEMPSN002A00). Tile accessory sensor must be mounted in the return airstream. See Fig. 35. Wiring is provided in the EconoMiSer [V wiring harness. See Fig. 27.

In this mode of operation, the outdoor-tfir temperature is

compared to the leturn-air temperature and the lower tempera- ture tfirstream is used for cooling. When using this mode of

changeover control, turn the enth_dpy setpoint potentiometer fully clockwise to the D setting. See Fig. 33.

Outdoor Enthalpy Changeover -- For enthalpy control, ac- cessory enthalpy sensor (p_ut number HH57AC078) is re- quired. Replace the standard outdoor chy bulb temperature sen- sor with the accessory enthalpy sensor in the same mounting

location. See Fig. 20. When the outdoor air enthalpy rises above the outdoor enthalpy changeover set point, the outdoor-

air damper moves to its minimum position. The outdoor enthalpy changeover set point is set with the outdoor enthalpy set point potentiometer on the EconoMiSer IV controller The set points are A, B, C, and D. See Fig. 36. The factory-installed 620-ohm jumper must be in place across terminals SR and SR+ on the EconoMiSer IV controllec See Fig. 20 and 37.

Differential Enthalpy Control -- For differential enthalpy control, the EconoMiSer IV controller uses two enthalpy sen- sors (HH57AC078 and CRENTDIF004A00), one in the out-

side air and one in the leturn air duct. The EconoMiSer [V controller comptues the outdoor air enthalpy to the return air

enthalpy to determine EconoMiSer IV use. The controller selects the lower enth_dpy air (return or outdoor) for cooling. For example, when the outdoor tfir has a lower enthalpy than the return tfir. the EconoMi$er IV opens to bring in outdoor air for free cooling.

Replace the standard outside air d U bulb temperatme sen-

sor with the accessory enthalpy sensor in the same mounting location. See Fig. 20. Mount the return air enthalpy sensor in

the leturn air duct. See Fig. 35. Wiring is provided in the EconoMiSer IV wiring harness. See Fig. 27. The outdoor en-

thalpy changeover set point is set with the outdoor enthalpy set point potentiometer on the EconoMiSer IV controllen When

using this mode of changeover control, turn the enthalpy set- point potentiometer fully clockwise to the D setting.

which the exhaust fans will be turned on. When there is a call for exhaust, the EconoMiSer IV controller provides a 45 _+15

second delay before exhaust fan activation to allow the damp- ers to open. This delay _fllows file damper to reach the appro- priate position to avoid unnecessaly fan overload.

Minimum Position Control -- There is a minimum damper position potentiometer on the EconoMiSer [V controllel: See

Fig. 33. The minimum damper position maintains the mini- mum airflow into the building during the occupied period.

When using demand ventihttion, the minimum dmnper po-

sition represents the minimum ventilation position for VOC (volatile organic compound) ventilation requirements. The

maximum demand ventilation position is used for fully occu- pied ventilation.

When demand ventilation control is not being used, the

minimum position potentiometer should be used to set the oc- cupied ventilation position. The maximum demand ventilation

position should be turned fully clockwise.

Adjust the minimum position potentiometer to allow the

minimum mnount of outdoor aik as required by local codes, to enter the building. Make minimum position adjustments with

at least 10 F temperature difference between the outdoor and return-air temperatures.

To determine the minimum position setting, perform the

following procedure:

1. Calculate the appropriate mixed air temperature using the following formula:

OA RA

(Tox I--F6_) +(TRx 1-Tff6-)=TM

To = Outdoor-Air Temperature OA = Percent of Outdoor Air

TR = Return-Air Temperature RA = Percent of Return Air

TM = Mixed-Air Temperature

As an example, if local codes require 10% outdoor tdr during occupied conditions, outdoor-air temperature is

60 E and return-air temperature is 75 E (60 x .10) + (75 x .90) =73.5 F

2. Disconnect the supply air sensor from terminals T and TI.

3. Ensure that the factou-installedjumper is in place across terminals P and PI. If remote damper positioning is being

used, make sure that the terminals am wired according to Fig. 27 and that the minimum position potentiometer is

turned fully clockwise.

4. Connect 24 vac across terminals TR and TRI.

5. CarefiJlly adjust the minimum position potentiometer until the measured supply air temperature matches the

calculated value.

6. Reconnect the supply _firsensor to termimds T and TI.

Remote control of the EconoMi$er IV damper is desirable when requiring additiomd temporm-y ventilation. If a field-supplied remote potentiometer (Honeywell part number $963B1128) is wired to the EconoMi$er IV controllek the

minimum position of the damper can be controlled from a m- mote location.

To control the minimum damper position remotely, remove the factory-installed jumper on the P and PI terminals on the

EconoMi$er IV controllel: Wire the field-supplied potentiome- ter to the P and PI terminals on the EconoMi$er IV controller.

See Fig. 37.

Damper Movement -- Damper movement trom full open to full closed (or vice versa) takes 2112minutes.

Thermostats -- The EconoMiSer IV control works with con- ventiomd thermostats that have a YI (cool stage 1), Y2 (cool

stage 2), Wl (heat stage 1), W2 (heat stage 2), and G (fan). The EconoMiSer IV control does not support space temperature

sensors. Connections are made at the thermostat termimd con- nection board located in the main control box.

Occupancy Control -- The facto U default configuration for the EconoMi$er IV control is occupied mode. Occupied status

is provided by the black jumper flom terminal TR to terminal N. When unoccupied mode is desired, inst_dla field-supplied timeclock function in place of the jumper between TR and N. See Fig. 27. When the timeclock contacts are closed, the EconoMi$er IV control will be in occupied mode. When the

timeclock contacts are open (removing the 24-v signal from terminal N), the EconoMi$er IV will be in unoccupied mode.

Demand Controlled Ventilation (DCV) -- When using the EconoMiSer IV for demand controlled ventilation, them are

some equipment selection criteria which should be considered.

When selecting the heat capacity and cool capacity of the

equipment, the maximum ventilation rote must be evaluated for design conditions. The maximum damper position must be cal-

culated to provide the desired fresh ail:

Typically the maximum ventilation rate will be about 5 to

10% morn than the typical chn required per person, using nor-

mid outside air design criteria.

A proportional anticipatory strategy should be taken with

the following conditions: a zone with a large area, varied occu- pancy, and equipment that cannot exceed the required ventila-

tion rate at design conditions. Exceeding the required ventila- tion rate means the equipment can condition air at a maximum

ventilation rate that is greater than the required ventilation rate for maximum occupancy. A proportional-anticipato U strategy

will cause the fresh air supplied to increase as the room CO2 level increases even though the CO2 set point has not been

reached. By the time the CO2 level roaches the set point, the damper will be at maximum ventilation and should maintain

the set point.

In order to have the CO2 sensor control the economizer

damper in this manner, fil.'stdetermine the damper voltage out- put for minimum or base ventilation. Base ventilation is the

ventilation required to remove contmninants during unoccu- pied periods. The following equation may be used to determine

the percent of outside-air entering the building for a given damper position. For best results there should be at least a

10 degree difference in outside and return-air temperatures.

OA RA

(To x l-T-ff_) + (TR x _ ) = TM

To = Outdoor-Air Temperature OA = Percent of Outdoor Air

TR= Return-Air Temperature RA = Percent of Return Air

TM= Mixed-Air Temperature

Once base ventilation has been determined, set the mini-

mum damper position potentiometer to the correct position.

The same equation can be used to deterlnine the occupied or

maximum ventilation rate to the building. For example, an out- put of 3.6 volts to the actuator provides a base ventilation rate

of 5% and an output of 6.7 volts provides the maximum venti- lation rate of 20% (or base plus 15 cfm per person). Use Fig. 38

to determine the maximum setting of the CO2 sensol: For ex- ample, a 1100 ppm set point relates to a 15cfm per person de-

sign. Use the 1100 ppm curve on Fig. 38 to find the point when the CO2 sensor output will be 6.7 volts. Line up the point on the

graph with the left side of the chart to determine that the range configuration for the CO2 sensor should be 1800 ppm. The

Dehumidification of Fresh Air with DCV Control -- Infor- mation from ASHRAE indicates that the largest humidity load

on any zone is the fresh air introduced. For some applications, a device such as a 62AQ energy recovery unit is added to re-

duce the moisture content of the fresh air being brought into the building when file enthalpy is high. In most cases, the normfd

Step 9 -- Adjust Evaporator-Fan Speed -- Ad-

just evaporator-fan rpm to meet jobsite conditions. Table 7

shows ffm rpm at motor pulley settings. Table 8 shows motor performance. See Table 9 for accessory and option static pres- sure drops. See Table 10 for evaporator-fan motor efficiency. Refer to Tables 11-40 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 diagram for motor reconnection. See Fig. 39 for direct-drive

motor location. BELT-DRIVE MOTORS- Fan motor pulleys are factory

set for speed shown in Tables IA and lB. See Fig. 40 for belt di'ive motor location.

NOTE: Before adjusting fan speed, make sure the new ffm speed will provide an air temperature rise range as shown in

Tables IA find lB. To change fan speed:

1. Shut offunit power supply.

2. Ix_osen belt by loosening fan motor mounting nuts. See Fig. 40.

3. Ix_osen movable pulley flange setscrew (see Fig. 41 ).

4. Screw movable flange toward fixed flange to increase speed and away from fixed flange to decrease speed. Increasing fan speed increases load on motol: Do not exceed maximum speed specified in Tables IA find lB.

5. Set movable flange fit nearest keyway of pulley hub and tighten setscrew. (See Tables 1A find 1B for speed change for each fifll turn of pulley flange.)

To align fan and motor pulleys:

1. Ix_osen fan pulley setscrews.

2. Slide fan pulley along fan shaft. Make angulm alignment by loosening motor from

mounting.

*Motor drive range: 875 to 1192 rpm. All other rpms require a field-

supplied drive.

Refer to this page for general Fan Performance Data notes.

NOTES:

1. Boldface indicates field-supplied drive is required,

2. Maximum continuous bhp is 1.30.

GENERAL NOTES FOR FAN PERFORMANCE DATA TABLES

1. Values include losses for filters, unit casing, and wet coils. See Table 9 for FlOP static pressure information.

2. Performance data is based on clean filters and a wet coil.

3. Extensive motor and electrical testing on these units ensures that the full range of the motor can be utilized with confidence.

Using the fan motors up to the wattage ratings shown will not result in nuisance tripping or premature motor failure. Unit

warranty will not be affected. See Evaporator-Fan Motor Perfor-

mance data in Table 8 on page 29 for additional information.

4. Use of a field-supplied motor may affect wire sizing. Contact your Carrier representative for details.

5. Interpolation is permissible. Do not extrapolate.

PRE-START-UP

Return-Air Filters--Make sure correct filters are installed in filter tracks. See Tables IA and lB. Do not operate

unit without return-air filters.

Failure to observe the following warnings could result in serious personal injury.

1. Follow recognized safety practices and wear protective goggles when checking or the servicing refrigerant system.

2. Do not operate the compressor or provide any electric power to the unit unless the compressor terminal cover is in place and secured.

3. Do not remove the compressor tenninal cover until all electrical sources are disconnected.

4. Relieve _dl pressme from the system before touching or disturbing anything inside the compressor tem_inal box if refrigerant leak is suspected around the compressor

terminals.

5. Never attempt to repair a soldered connection while the _efrigerant system is under pressure.

6. Do not use torch to remove any component. The sys- tem contains oil and refiigerant under pressure. To lemove a component, wear protective goggles and pro-

ceed as follows: a. Shut off gas and then electrical power to the unit.

Install lockout tag.

b. Relieve all pressure from the system using both

high-pressure and low-plessure ports. Recover refrigerant.

c. Cut the component connection tubing with a tubing

cuttec and remove the component from the unit.

d. Cmefully unsweat the remaining tubing stubs when

necess_uy. Oil can ignite when exposed to torch flmne.

Proceed as follows to inspect and prepare the unit for initi_fl

start-up:

1. Remove all access panels.

2. Read and follow instructions on all WARNING. CAU-

TION, and INFORMATION labels attached to, or shipped with, the unit.

3. Make the following inspections:

a. Inspect for shipping and handling dmnages such as

broken lines, loose parts, or disconnected wires, etc.

b. Inspect for oil at all refiigerant tubing connections

and on unit base. Detecting oil generally indicates a refrigerant leak. Leak-test all refrigerant tubing con- nections using an electronic leak detectol; halide torch, or liquid-soap solution.

c. Inspect all field- and factory-wiring connections. Be

sure that connections are completed and tight.

d. Inspect coil fins. If damaged during shipping and han-

dling, cm'elhlly straighten the fins with a fin comb.

4. Verify the following conditions:

a. Make sure that condenser fan blade is correctly

positioned in the fan orifice. See Condenser-Fan Adjustment section on page 58 for more details.

b. Make sure that air filter(s) is in place. c. Make sure that condensate di'ain trap is filled with

water to ensure proper drainage.

d. Make sine that all tools and miscellaneous loose parts

have been removed.

START-UP

Unit Preparation--Make sure that unit has been

installed in accordance with these installation instructions and applicable codes.

Compressor Mounting -- Compressors m'e internally

spring mounted. Do not loosen or remove compressor hold- down bolts.

Internal Wiring- Check all electrical connections in

unit control boxes. Tighten as required. Gas Piping -- Check gas piping for leaks.

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 plessure testing field- supplied gas piping at pressures of 1/2 psig

or less, a unit connected to such piping must be isolated by manu_flly closing the gas valve.

Refrigerant Service Ports-- To service refiigerant

service ports, remove compressor access panel. Each unit sys- tem has 3 Schmder-type service gage ports: one on the suction line, one on the liquid line, and one on the compressor dis- charge line. Be sine that caps on the ports me tight. The Schmder-type valve on the dischmge line is located under the low-pressure switch. Another valve is located on the dischmge line underneath the high-pressure switch. It is screwed on a Schmder fitting but there is no Schmder core.

High Flow Valves -- Located on the compressor hot gas

and suction tubes me High Flow Valves. Lm'ge black plastic caps distinguish these valves with O-rings located inside the caps. These valves cannot be accessed for service in the field. Ensure the plastic caps me in place and tight or the possibility of refrigerant leakage could occur

Compressor Rotation -- On 3-phase units with scroll

compressors, it is important to be certain compressor is rotating in the proper direction. To determine whether or not compres-

sor is rotating in the proper direction:

1. Connect service gages to suction and dischmge pressure fittings.

2. Energize the compressoc

3. The suction pressure should drop and the discharge pres- sure should rise, as is norm;fl on any st;u't-up.

If the suction pressure does not diop and the discharge pres-

sure does not rise to normal levels:

1. Note that the evaporator fan is probably also rotating in the wrong dilection.

2. Turn off power to the unit.

3. Reverse any two of the unit power leads.

4. Reapply power to the compressol:

The suction and discharge pressure levels should now move

to their normal start-up levels. NOTE: When the compressor is rotating in the wrong dilec-

tion, the unit makes an elevated level of noise and does not provide cooling.

Page 46

Cooling -- Set space thermostat to OFF position. To st_ul

unit, turn on main power supply. Set system selector switch at COOL position and fan switch at AUTO. position. Adjust ther- mostat to a setting below room temperature. Compressor starts

on closure of contacto_:

Check unit chmge. Refer to Refrigerant Charge section,

page 49.

Reset thennostat at a position above room temperature. Compressor will shut off. Evaporator fan will shut off after 30-second delay.

TO SHUT OFF UNIT -- Set system selector switch at OFF position. Resetting thermostat at a position above room tem- perature shuts unit off temporarily until space temperature ex- ceeds therlnostat setting.

Main Burners-- Main burnel_ _ue factory set and should

require no adjustment. TO CHECK ignition of main burners and heating controls,

move thermostat set point above room temperature and verify that the burners light and evaporator fan is energized. After ensuring that the unit continues to heat the building, lower the thermostat setting below room temperature and verify that the burners and evaporator fan turn off. (Fan will turn off only if fan selector switch is in the AUTO. position.)

Heating

1. Purge gas supply line of air by opening union ahead of

gas valve. If gas odor is detected, tighten union and wait 5 minutes before proceeding.

2. Turn on electrical supply and manual gas valve.

3. Set system switch selector at HEAT position and fan switch at AUTO. or ON position. Set heating temperature

lever above room temperature.

4. The induced-draft motor will start.

5. After a call for heating, the main burnel_ should light within 5 seconds. If the burner does not light, then there is

a 22-second delay before another 5-second try. If the burner still does not light, the time delay is repeated. If the

burner does not light within 15 minutes, there is a lock- out. To reset the control, break the 24-v power to WI.

6. The evaporator-fan motor will turn on 45 seconds after the burners me ignited.

7. The evaporator-fan motor will turn off 45 seconds after thermostat temperature is satisfied.

8. Adjust airflow to obtain a temperature rise within the range specified on the unit nameplate.

NOTE: The default value for the evaporator-fan motor ON/ OFF delay is 45 seconds. The Integrated Gas Unit Controller

(IGC) modifies this value when abnormal limit switch cycles occm: Based upon unit operating conditions, the ON delay can be reduced to 0 seconds and the OFF delay can be extended to

180 seconds. When one flash of the LED is observed, the

evaporator-fan ON/OFF delay has been modified.

If the limit switch trips at the stm-t of the heating cycle dur-

ing the evaporator ON delay, the time period of the ON delay for the next cycle will be 5 seconds less than the time at which

the switch tripped. (Example: If the limit switch trips at 30 sec- onds, the evaporator-fan ON delay for the next cycle will occur

at 25 seconds.) To prevent short-cycling, a 5-second reduction will only occur if a minimum of 10 minutes has elapsed since the last call for heating.

Page 47

Theevaporator-fanOFFdelaycanalsobemodified.Once

thecallforheatinghasended,thereis a 10-minute period dur-

ing which the modification can occm: If the limit switch trips dining this period, the evaporator-fan OFF delay will increase by 15 seconds. A maximum of 9 trips can occm: extending the

evaporator-fan OFF delay to 180 seconds.

To restore the original default value, reset the power to the

unit. TO SHUT OFF UNIT -- Set system selector switch at OFF

position. Resetting heating selector lever below room tempera- ture will temponuily shut unit off until space temperature falls below thermostat setting.

Safety Relief --A soft solder joint at the suction service

Schmder port provides pressure relief under abnorln_d tempera- ture and pressure conditions (i.e., fire in building).

Ventilation (Continuous Fan) -- Set fan and system

selector switches at ON and OFF positions, lespectively. Evaporator ftm operates continuously to provide constant air circulation. When the evaporator-fan selector switch is turned to the OFF position, there is a 30-second delay before the fan

turns off.

Operating Sequence

COOLING. UNITS WITHOUT ECONOMIZER -- When thermostat c_flls for cooling, terminals G and YI me energized.

The indoor-fan contactor (IFC) and compressor contactor are energized and indoor-fan motor, compressol: and outdoor fan staffs. The outdoor fan motor runs continuously while unit is cooling.

HEATING. UNITS WITHOUT ECONOMIZER --When the thermostat calls for heating, terminal Wl is energized. To pre-

vent thermostat short-cycling, the unit is locked into the Heating mode for at least 1 minute when WI is energized. The induced-draft motor is energized and the burner ignition sequence begins. The indoor (evaporator) fan motor (IFM) is energized 45 seconds after a flame is ignited. On units equipped for two stages of heat, when additional heat is need- ed. W2 is energized and the high-file solenoid on the main gas valve (MGV) is energized. When the thermostat is satisfied and WI is deenergized, the IFM stops after a 45-second time- off delay.

COOLING UNITS WITH ECONOMISER IV -- When flee cooling is not available, the complessors will be controlled by

the zone themlostat. When flee cooling is available, the outdoor-air damper is modulated by the EconoMiSer IV control to provide a 50 to 55 F supply-air temperature into the zone. As the supply-air tempemtme fluctuates above 55 or below 50 IF. the dampel_ will be modulated (open or close) to bring the sup- ply-air temperature back within the set point limits.

Integrated EconoMiSer IV operation on single stage units

requires a 2-stage thermostat (YI and Y2).

For EconoMiSer IV operation, there must be a thermostat call for the fan (G). This will move the damper to its minimum position during the occupied mode.

If the increase in cooling capacity causes the supply-air tem- perature to drop below 45 F, then the outdoor-air &tmper posi-

tion will be liflly closed. If the supply-air temperature contin- ues to ftdl, the outdoor-air dmnper will close. Control leturns to nomml once the supply-air temperature rises above 48 E

If optional power exhaust is installed, as the outdoor-air damper opens and closes, the power exhaust fans will be ener- gized and deenergized.

If field-installed accessory CO2 sensors are connected to the EconoMiSer IV control, a demand controlled ventilation strate-

gy will begin to operate. As the CO2 level in the zone increases above the CO2 set point, the minimum position of the &tmper

will be increased proportionally. As the CO2 level decreases because of the increase in fresh ail: the outdoor-air damper will

be proportionally closed. Damper position will follow the high- er demand condition fi_m DCV mode or free cooling mode.

Dalnper movement from full closed to full open (or vice

versa) will take between 11/2and 21/2 minutes.

If free cooling can be used as determined fi_m the appropri-

ate changeover command (switch, dry bulb, enthalpy curve, differential dry bulb, or differential enthalpy), a call for cooling

(YI closes at the thermostat) will cause the control to modulate the dampers open to maintain the supply air temperature set point at 50 to 55 E

As the supply-air temperature drops below the set point

range of 50 to 55 F. the control will modulate the outdoor-air &tmpers closed to maintain the proper supply-air temperature.

HEATING. UNITS WITH ECONOMISER IV -- When the room temperature calls for heat, the heating controls are ener-

gized as described in the Heating, Units Without Economizer section. When the thermostat is satisfied, the economizer

&tmper moves to the minimum position. COOLING. UNITS WITH ECONOMISER2, PREMIER-

LINK TM CONTROL AND A THERMOSTAT -- When free cooling is not available, the compressors will be controlled by the PremierLink control in response to the YI and Y2 inputs

fiom the thermostat.

The PremierLink control will use the following information

to determine if flee cooling is available:

• Indoor fan has been on for at least 30 seconds.

• The SPT. SAT. and OAT inputs must have valid readings.

• OAT must be less than 75 E

• OAT must be less than SPT.

• Enthalpy must be LOW (may be jumpered if an enthalpy sensor not available).

• Economizer position is NOT forced. Pre-cooling occurs when the is no call from the thermostat

except G Pie-cooling is defined as the economizer modulates to provide 70 F supply all:

When free cooling is awtilable the PremierLink control will

control the compressors and economizer to provide a supply- air temperature determined to meet the YI and Y2 calls from

the thermostat using the following thlee routines. The three control routines are based on OAT.

The 3 routines are based on OAT where: SASP = Supply Air Set Point

DXCTLO = Direct Expansion Cooling Lockout Set Point PID = Proportional Integral Routine 1 (OAT < DXCTLO)

• YI energized - economizer maintains a SASP = (SATLOI + 3).

• Y2 energized - economizer maintains a SASP = (SATLO2 + 3).

Routine 2 (DXCTLO < OAT < 68 F)

• If only YI energized, the economizer maintains a SASP = (SATLOI + 3).

• If SAT > SASP + 5 and economizer position > 80%, economizer will go to minimum position for 3 minutes or

until SAT > 68 E

• First stage of mechanical cooling will be energized.

• Integrator resets.

• Economizer opens again and controls to current SASP after stage one on for 90 seconds.

• With YI and Y2 energized Economizer maintains an SASP = SATLO2 + 3.

Page 48

• If SAT > SASP + 5 and economizer position >80%,

economizer will go to minimum position for 3 minutes or until SAT > 68 IF.

• If compressor one is on then second stage of mechanical

cooling will be energized. Otherwise the first stage will be energized.

• Integrator resets.

• Economizer opens again and controls to SASP after stage one on for 90 seconds.

Routine 3 ((-)AT > 68)

• Economizer is opened 100%.

• Compressors 1 and 2 are cycled based on YI and Y2 using minimum on and off times and watching the sup-

ply air temperature as compared to SATLOI and SATLO2 set points.

If optional power exhaust is installed, as the outdoor-air

damper opens and closes, the power exhaust fans will be ener- gized and deenergized.

If field-inst_dled accessory CO2 sensors ale connected to the

PremierLink TM control, a PlD-controlled demand ventilation strategy will begin to operate. As the CO2 level in the zone

increases above the CO: set point, the minimum position of the dmnper will be increased proportionally. As the CO2 level

decreases because of the increase in fresh aik the outdoor-air dmnper will be proportionally closed.

HEATING, UNITS WITH ECONOMISER2, PREMIERLINK CONTROL AND A THERMOSTAT -- When the thermostat

calls for heating, terminal Wl is energized. The PremierLink control will move the economizer damper to the minimum po-

sition if there is a call for G and closed if there is a call for WI without G In order to prevent themlostat from short cycling, the unit is locked into the heating mode for at least 10 minutes

when WI is energized. The induced-draft motor is then ener- gized and the burner ignition sequence begins.

On units equipped for two stages of heat, when additional

heat is needed, W2 is energized and the high-fire solenoid on the main gas valve (MGV) is energized. When the thermostat

is satisfied and WI is deenergized, the IFM stops after a 45-second time-off delay unless G is still maintained.

COOLING. UNITS WITH ECONOMISER2, PREMIER- LINK CONTROL AND A ROOM SENSOR -- When free

cooling is not available, the compressors will be controlled by the PremierLink controller using a PID Error reduction calcula-

tion as indicated by Fig 42.

The PremierLink controller will use the following informa-

tion to determine if free cooling is available:

• Indoor fan has been on for at least 30 seconds.

• The SPT. SAT. and OAT inputs must have valid readings.

• OAT must be less than 75 F.

• OAT must be less than SPT.

• Enthalpy must be LOW (may be jumpered if and enthalpy sensor is not available).

• Economizer position is NOT forced. When free cooling is available, the outdoor-air dalnper is po-

sitioned through the use of a Proportional Integral (PlD) control process to provide a calculated supply-air temperature into the

zone. The supply air will maintain the space temperature be- tween the heating and cooling set points as indicated in Fig. 43.

The PremierLink control will integrate the compressol:s

stages with the economizer based on simihu logic as the three routines listed in the previous section. The SASP will float up and down based on the error reduction calculations that com-

ptue space temperature and space set point.

When outside-air temperature conditions require the econo-

mizer to close for a compressor stage-up sequence, the economizer control integrator is reset to zero after the stage-up

sequence is completed. This prevents the supply-air tempera- ture from dropping too quickly and creating a freeze condition

that would make the compressor turn off prematurely.

The high space set point is used for DX (direct expansion)

cooling control, while file economizer space set point is a calculated value between the heating and cooling set points.

The economizer set point will always be at least one degree below the cooling set point, allowing for a smooth transition

from mechanical cooling with economizer assist, back to economizer cooling as the cooling set point is achieved.

The compressors may be used for initial cooling then the PremierLink controller will modulate the economizer using an error reduction calculation to hold the space temperature between the heating and cooling set points. See Fig. 43.

The controller uses the following conditions to determine

economizer cooling:

• Enthalpy is Low

• SAT reading is available

• OAT reading is available

• SPT reading is available

• OAT < SPT

• Economizer Position is NOT forced If any of the above conditions are not met, the economizer

submaster reference (ECSR) is set to maximum limit and the damper moves to minimum position. The operating sequence

is complete. The ECSR is recalculated every 30 seconds.

If an optional power exhaust is installed, as the outdoor-air

damper opens and closes, the power exhaust fans will be energized and deenergized.

If field-installed accessory CO2 sensors tue connected to

the PremierLink control, a PID-controlled demand ventilation strategy will begin to operate. As the CO, level in file zone increases above the CO2 set point, the minimum position of the

damper will be increased proportionally. As the CO2 level decreases because of the increase in flesh aik the outdoor-air

damper will be proportionally closed.

HEATING. UNIT WITH ECONOMISER2, PREMIERLINK rM CONTROL AND A ROOM SENSOR --Every 40 seconds

the controller will calculate the required heat stages (maximum of 3) to maintain supply-air temperature (SAT) if the following qu_difying conditions ale met:

• Indoor fan has been on for at least 30 seconds.

• COOL mode is not active.

• OCCUPIED, TEMRCOMPENSATED START or HEAT mode is active.

• SAT reading is available.

• Fire shutdown mode is not active. If all of the above conditions are met, the number of heat

stages is c_dculated; otherwise file required number of heat stages will be set to 0.

If the PremierLink controller determines that heat stages are

required, the economizer damper will be moved to minimum position if occupied and closed if unoccupied.

Staging should be as follows: If Heating PID STAGES=2

• HEAT STAGES=I (50% capacity) will energize HSI

• HEAT STAGES=2 (100% capacity) will energize HS2 If Heating PID STAGES=3 and AUXOUT = HS3

• HEAT STAGES=I (33% capacity) will energize HSI

• HEAT STAGES=2 (66% capacity) will energize HS2

• HEAT STAGES=3 (100% capacity) will energize HS3 In order to prevent short cycling, the unit is locked into the

Heating mode for at least 10 minutes when HS 1 is deenergizedi

When HSI is energized the induced-&aft motor is then

energized and the burner ignition sequence begins. On units equipped for two stages of heat, when additional heat is need-

ed, HS2 is energized and the high-fire solenoid on the m_fin gas valve (MGV) is energized. When the space condition is

satisfied and HSI is deenergized the IFM stops after a 45-sec- ond time-off delay unless in the occupied mode. The fan will

mn continuously in the occupied mode as required by natiomfl energy and fresh air standards.

NOTE: This procedure _equires a 9-v battery. 1.2 kilo-ohm resistol: and a 5.6 kilo-ohm lesistor which are not supplied

with the EconoMi$er IV.

IMPORTANT: Be sure to record the positions of all poten-tiometers before starting troubleshooting.

1. Disconnect power at TR and TRI. All LEDs should be off. Exhaust fan contacts should be open.

2. Disconnect device at P and PI.

3. Jumper P to PI.

4. Disconnect wires at T and TI. Place 5.6 kilo-ohm resistor across T and TI.

5. Jumper TR to 1.

6. Jumper TR to N.

7. If connected, remove sensor from terminals So and +. Connect 1.2 kilo-ohm 4074EJM checkout resistor across

terminals So and +.

8. Put 620-ohm resistor across terminals SR and +.

9. Set minimum position, DCV set point, and exhaust potentiometers fully CCW (counterclockwise).

10. Set DCV maximum position potentiometer fiJlly CW

(clockwise).

11. Set enthalpy potentiometer to D.

12. Apply power (24 vac) to terminals TR and TRI.

DIFFERENTIAL ENTHALPY-- To check differential enthalpy:

1. Make sure EconoMiSer IV prepmation procedure has been performed.
