SAFETY CONSIDERATIONS

Installation and sel-,Ticingof 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 ai>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 ai>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 extinguishers available for all brazing operations.

Ensum voltage listed on unit data plate agmes with electri-

c_dsupply provided for the unit.

Disconnect gas piping fi_m unit when leak

testing at pressure greater than I/2 psig. Pms-

sums greater than ]12psig will cause gas valve

damage resulting in haz_u'dous condition. If

gas valve is subjected to pressure greater than

1/2 psig, it must be replaced before use. When

_ressure testing field-supplied gas piping at

?ressures of 1/2 psig or less, a unit connected to

;uch piping must be isolated by manu_dlyclos-

ing the gas valve(s).

Before performing service or maintenance operations on

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

could cause personal injury.

INSTALLATION

Unit is shipped in the vertical configuration. To convert to

horizont_flapplication, remove side duct opening covers. Using

the same scmws, install coveLs on vertical duct openings with

the insulation-side down. Seals around duct openings must be

tight. See Fig. 1.

Step 1 -- Provide Unit Support

ROOF CURB -- Assemble and install accesso Uroof 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. If electric or

control power 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. Con-

nections must be installed befom unit is set on roof curb.

IIMPORTANT: The gasketing of the unit to the roof curb is I

critical for a watertight seal. Install gasket supplied with the I

roof curb as shown in Fig. 2. hnproperly applied gasket can

also result in air leaks and poor unit performance.

Curb should be level. This is necessary for unit drain to

function properly. Unit leveling tolerances am shown in Fig. 3.

Refer to Accessory Roof Curb Installation Instructions for

additional infomtation as requimd.

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

Catalog No. 04-53480012-01 Printed in U,S.A, Form 48HJ-32SI Pg 1 9-05 Replaces: 48HJ-28SI

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

plevent 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

adapter support alea. If sleepel_ 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 vertical

units, secure all ducts to roof curb and building structure. Do

not connect duct_'ork to unit. For horizont_fl applications, field-

supplied flanges should be attached to horizontal discharge

openings and all ductwoN secured to the flanges. Insulate 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

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 requiled around ductwork.

Cabinet return-air static pressure (a negative condition) shall

not exceed 0.35 in. wg with economizer or 0.45 in. wg without

economizel:

These units are designed for a minimum continuous return-

air temperature in heating of 50 F (c_h_bulb), or an intermittent

operation down to 45 F (r_h_ bulb), such as when used with a

night set-back thermostat.

To operate at lower return-air temperatures, a field-supplied

outdoor-air temperature control must be used to initiate both

stages of heat when the temperature is below 45 E Indoor com-

fort may be compromised when these lower air temperatures

are used with insufficient heating temperature rise.

Step 3 -- Determine Location of Drain Line

and External Trap -- The unit's 3/4-in. condensate &ain

connections are located on the bottom and end of the unit. Unit

discharge connections do not determine the use of c_h'aincon-

nections; either c_h'ainconnection can be used with vertical or

horizontal applications.

When using the standard end c_h'_dnconnection, make sure

the plug in the alternate bottom connection is tight before in-

stalling the unit.

To use the bottom drain connection for a roof curb installa-

tion, lelocate the factory-installed plug from the bottom con-

nection to the end connection. The center c_hainplug looks like

a star connection, however it can be removed with a l/2-in.

socket c_hive extension. See Fig. 4. The piping for the conden-

sate c_h'ainand external trap can be completed after the unit is in

place.

All units must have an extern_fl trap for condensate &'ain-

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

up. See Fig. 5. If drain line is installed downsheam from the

extern_fl 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.

Step 4 -- Rig and Place Unit -- Inspect unit for

transportation &unage. File any clainl with transpoltation

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

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

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

ence. See Table 1 and Fig. 6 for additional information. Operat-

ing weight is shown in Table 1 and Fig. 6.

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

and 7. Refer to rigging instructions on unit.

POSITIONING -- Maintain clearance around and above unit

to provide minimum distance fiom combustible materi_ds,

proper airflow, and service access. See Fig. 7.

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

air inlets near exhaust vents or other sources of contaminated

all:

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 fiom

higher level runoff and overhangs.

Position unit on roof curb so that the following clearances

are maintained: l/4-in, clearance between the roof curb and the

base rail inside the front and real: 0.0 in. clearance between the

roof curb and the base rail inside on the duct end of the unit.

This will result in the distance between the roof curb and the

base rail inside on the condenser end of the unit being approxi-

mately equal to Fig. 2, section C-C.

Ix_cate mechanical draft system flue assembly at least 48 in.

from an adjacent building o1 combustible material. Units hav-

ing accessory flue dischmge deflector lequire only 18 in. clear-

ance. When unit is located adjacent to public walkways, flue

assembly must be at least 7 ft above grade.

Flue gas can deteriorate building materi_ds. Orient unit so

that flue gas will not affect building materials.

Adequate combustion and ventilation air space must be pro-

vided for proper operation of this equipment. Be sure that in-

stallation complies with all local codes and Section 5.3, Air for

Combustion and Ventilation per NFGC (Natiomd Fuel Gas

Code), ANSI (American National Standards Institute) Z223.1 -

latest year and addendum Z223.1A-latest yem: In Canada, in-

stallation must be in accordance with the CANI.BI49.1 and

CAN 1.B 149.2 installation codes for gas burning appliances.

Flue vent dischmge must have a minimum horizontal clear-

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

gas relief equipment.

After unit is in position, remove shipping materials and rig-

ging skids.

Step 5 -- Install Flue Hood -- Flue hood is shipped

screwed to the burner compartment access panel. Remove

fiom shipping location and, using screws provided, inst_dl flue

hood and screen in location shown in Fig. 7 and 8.

Step 6 -- Install Gas Piping -- Unit is equipped for

use with type of gas shown on nameplate. Refer to local

building codes, or in the absence of local codes, to

ANSI Z223.l-latest year and addendum Z223. l A-latest year

entitled NFGC. In Cana&t, installation must be in accordance

with the CANI .B149.1 and CANI .B149.2 installation codes

for gas burning appliances.

For natund gas applications, gas pressure at unit gas

connection must not be less than 4.0 in. wg or greater than

13.0 in. wg while unit is operating. For liquid propane and high

heat applications, the gas pressure must not be less than

5.0 in. wg or greater than 13.0 in. wg at the unit connection.

Size gas supply piping for 0.5-in. wg maximum pressure

drop. Do not use supply pipe sm_fller than unit gas connection.

Support gas piping as shown in the table in Fig. 9. For ex-

ample, 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 3 support beams. See Fig. 9 for typic_d pipe guide

and locations of external manual gas shutoff valve.

When connecting the gas line to the unit gas valve, the

installer MUST use a backup wrench to prevent valve

&_mage.

Step 7 -- Make Electrical Connections

Unit cabinet must have an uninterrupted, unbroken electri-

cal ground to minimize the possibility of personal inju Uif

an electrical fault should occm: This ground may consist of

electrical wire connected to unit ground lug in control com-

partment, or conduit appl_)ved for electrical ground when

installed in accordance with NEC (National Electrical

Code), ANSI/NFPA (National File Protection Associa-

tion), latest edition, and local electrical codes. Do not use

gas piping as an electrical ground. Failure to follow this

warning could result in the inst_dler being liable for per-

somd inju Uof 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

supply, the transformer must be rewired by moving the black

wire fiom the 230-v orange wile on the transformer and

connecting it to the 200-v red wire fiom the transformer The

orange wire then must be insulated.

Refer to unit label diagram for additional infommtion.

Pigtails are provided for field service. Use factou-supplied

splices or UL (Undelwriters' Laboratories) approved copper

connectoL

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 Standads Associaion) C22.1 Canadian

Electrical Code Part One.

Install conduit through side panel openings indicaed in

Fig. 7. Route power lines through connector to terminal con-

nections as shown in Fig. 10.

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

anced within 2% and the current within 10%. Use the fommla

shown in Note 3 under Tables 2A-2D to determine the percent-

age of voltage imbalance. Operation on improper line voltage

or excessive phase imbalance constitutes abuse and may cause

&image to electric_fl components. Such operation would inv_fli-

&tte any applicable Carrier warranty.

NOTE: If thru-the-bottom accesso Uconnections are used,

refer to the thin-the-bottom accessol T installation instructions

for power wiring. Refer to Fig. 7 for location to &ill holes in

basepan.

FIELD CONTROL WIRING -- Install a Carrier-approved

accesso Uthermostat assembly according to inst_dlation in-

structions included with the accesso U. Ix)cate thermostat

assembly on a solid wall in the conditioned space to sense

average temperature in accordance with thermostat installation

instructions.

Route thermostat cable or equivalent single leads of colored

wire from thermostat subbase terminals to low-voltage connec-

tions on unit (shown in Fig. IIA and lIB) as described in

Steps 1-4 below.

1. ff unit is mounted on roof curb and accesso Uthru-the-

bottom connections are used, route wire through connec-

tion plate.

2. Pass control wires through the hole provided on unit (see

connection D, Connection Sizes table, Fig. 7).

3. 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. 12. The raceway provides the UL-required

clearance between high-voltage and low-voltage wiring.

4. Connect thermostat wires to screw terminals of low-

voltage connection boad (see Fig. 11A and 11B).

HUMIDI-MIZER TM ADAPTIVE DEHUMIDIFICATION

SYSTEM -- Humidi-MiZer a&_ptive dehumidification

system operation can be controlled by field installation of

aCarrier-approved humidistat (Fig. 13).

NOTE: A light commercial Thermidistat TM device (Fig. 14)

can be used instead of the humidistat if desired. The

Thermidistat device includes a thermostat and a humidistat.

The humidistat is norm_dly used in applications where a tem-

perature sensor is aheady provided (units with PremierLink TM

control).

To install the humidistat:

1. Route humidistat cable through hole provided in unit

corner post.

2. 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. 12. The laceway provides the UL-required

cle_uance between high-voltage and low-voltage wiring.

3. Use a wire nut to connect humidistat cable into low-

voltage wiring as shown in Fig. 15.

To install a Thermidistat device:

1. Route Thermidistat cable through the hole provided in

unit corner post.

2. Feed the wires through the raceway built into file corner

post to the 24-v barrier located on the left side of the con-

trol box. See Fig. 12. The raceway provides the UL-

required clearance between high and low voltage wiling.

3. A field-supplied relay must be installed between the ther-

midistat and the Humidi-MiZer circuit (recommended re-

lay: HN612KK324). The relay coil is connected between

the DEHUM output and C (common) of the unit. Refer to

Fig. 16. The relay controls the Humidi-MiZer solenoid

valve and must be wired between the Humidi-MiZer fuse

and the low-pressure switch. Refer to the installation in-

structions included with the Carrier LigN Commercial

NOTES:

1. In compliance with NEC requirements for multimotor and combination load

3. 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 volt-

age imbalance.

% Voltage Imbalance

= 100 x max voltage deviation from average voltage

average voltage

Example: Supply voltage is 460-3-60.

AB = 452 v

ABC BC = 464 v

AC =455v

Average Voltage = 452 + 464 + 455

1371

457

Determine maximum deviation from average voltage.

(AB) 457 -452 = 5 v

(BC) 464 - 457 = 7 v

(AC) 457 - 455 = 2 v

Maximum deviation is 7 v.

Determine percent of voltage imbalance,

% Voltage Imbalance =100 x 45_

= 1,53%

This amount of phase imbalance is satisfactory as it is below the maximum

allowable 2%.

IMPORTANT: If the supply voltage phase imbalance is more than 2%, con-

tact your oca e ectr cut ty company turned ate y.

NOTE: If a single power source is to be used, size wire to include power

exhaust MCA and MOCR

Check MCA and MOCP when power exhaust is powered through the unit.

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 48HJD008 unit with MCA = 38.2 and MOCP = 45, with

CRPWREXH030A01 power exhaust.

MCA New = 38.2 amps + 1.6 amps = 39.8 amps

If the new MCA does not exceed the published MOCE then MOCP would not

change. The M©CP in this example is 45 amps and the MCA New is below

45; therefore the MOCP is acceptable. If MCA New" is larger than the pub-

lished M©CP, raise the MOCP to the next larger size. For separate power, the

MOCP for the power exhaust will be 15 amps per NEC.

3. Unbalanced 3-Phase Supply Voltage

Never operate a motor where, a pbase imbalance in supply voltage is

greater than 2_, Use the following formula to determine the percent of volt-

age imbalance.

% Voltage Imbalance

= 100 x max voltage deviation from average voltage

average voltage

Example: Supply voltage is 460-3-60.

A B c AB = 452 v

BC = 464 v

AC = 455 v

Average Voltage - 482 + 464 + 455

1371

457

Determine maximum deviation from average voltage.

(AB) 487 - 482 = 5 v

(BC) 464 - 487 = 7 v

(AC) 457 - 488 = 2 v

Maximum deviation is 7 v.

Determine percent of voltage imbalance.

% Voltage Imbalance = 100 x 457

= 1.53%

This amount of phase imbalance is satisfactory as it is below the maximum

allowable 2%.

IMPORTANT: If the supply voltage phase imbalance is more than 2%, con- I

tact your local electric utility company immediately. I

N/A -- Not available

NOTE: If a single power source is to be used, size wire to include power

exhaust MCA and MOCR

Check MCA and MOCP when power exhaust is powered through the unit.

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 48HJD008 unit with MCA = 38.2 and MOCP = 45, with

CRPWREXH030A01 power exhaust.

MCA New = 38.2 amps + 1.6 amps = 39.7 amps

If the new MCA does net exceed the published MOCE then MOCP would net

change. The MOCP in this example is 48 amps and the MCA New is below

45; therefore the MOCP is acceptable. If "MCA New" is larger than the pub-

lished MOCE raise the MOCP to the next larger size. For separate power, the

MOCP for the power exhaust will be 15 amps per NEC.

CONVENIENCE OUTLET -- An optional convenience out-

let provides power for rooftop use. For maintenance personnel

safety, the convenience outlet power is off when the unit dis-

connect is off. Adjacent unit outlets may be used for service

tools. An optional "Hot Outlet" is available from the factory as

PREMIERLINK TM CONTROL -- The PremierLink control-

let is compatible with Carrier Comfoll 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 standiu'd unit control board. Career's diagnostic

standard tier display tools such as Navigator or Scrolling Mar-

quee can be used wifll the PmmierLink controflel:

The PremielLink controller (see Fig. 21A and 21 B) 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 an option. Refer to Table 3 for

sensor usage. Refer to Fig. 22 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 Themlostat mode.

Install the Supply Air Temperature (SAT) Sensor -- 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 the

PmmierLink control over the control box, through a grommet,

into the fan section, down along the back side of the fan, and

_flong the fan deck over to the supply-air opening.

The SAT probe is wire-tied to file 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 secme 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 any of the unit

or heat surfaces.

Outdoor DLy Bulb Changeover -- The standald controller is

shipped from the factory configured for outdoor dry bulb

changeover control. The outdoor air and supply air temperature

sensors tue included as stan&u'd. For this control mode, file out-

door temperature is compared to an adjustable set point selected

on file control. If the outdoor-air temperature is above the set

point, the EconoMi$er IV will adjust file outdoor-air dampers to

minimum position. If the outdoor-air temperature is below the

set point, the position of the outdoor-air &unpel.s will be con-

trolled to provide free cooling using outdoor aic When in this

mode, file LED next to file free cooling set point potentiometer

will be on. The changeover temperature set point is controlled

by the free cooling set point potentiometer located on file con-

trol. See Fig. 38. The sc_de on the potentiometer is A, B, C, and

D. See Fig. 39 for the conesponding temperature changeover

values.

Differential Dry Bulb Control -- For differential dry bulb

control file standard outdoor chy bulb sensor is used in conjunc-

tion with an additional accessory dry bulb sensor (part number

CRTEMPSN002A00). The accessoq sensor must be mounted

in the return airstream. See Fig. 40. Wiring is provided in the

EconoMi$er IV wiring htuness. See Fig. 32.

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

compared to the return-air temperature and the lower tempera-

ture air stremn is used for cooling. When using this mode of

changeover control, turn the enthalpy setpoint potentiometer

fully clockwise to the D setting. See Fig. 38.

Outdoor Enthalpy Changeover -- For enthalpy control, ac-

cessory enthalpy sensor (p_ut number HH57AC078) is re-

quired. Replace the standard outdoor @ bulb temperature sen-

sor with file accessory enthalpy sensor in the same mounting

location. See Fig. 25. When the outdoor air enfllalpy rises

above the outdoor enthalpy changeover set point, file outdoor-

air damper moves to its minimum position. Tile outdoor

enthalpy changeover set point is set with the outdoor enth_dpy

set point potentiometer on the EconoMi$er IV controllel: The

set points are A, B, C, and D. See Fig. 41. The factory-installed

620-ohln jumper must be in place across terminals SR and SR+

on the EconoMiSer IV controllel: See Fig. 25 and 42.

Differential Enthalpy Control -- For differential enth_dpy

control, the EconoMiSer IV controller uses two enthalpy sen-

sors (HH57AC078 and CRENTDIF004A00), one in the out-

side air and one in the return air duct. The EconoMiSer IV

controller compmes file outdoor air enthalpy to the return air

enthalpy to determine EconoMiSer IV use. The controller

selects the lower enthalpy air (return or outdoor) for cooling.

For example, when the outdoor air has a lower enthalpy than

the return air. the EconoMiSer IV opens to bring in outdoor air

for free cooling.

Replace the standard outside air din bulb temperature sen-

sor with the accessory enthalpy sensor in the same mounting

location. See Fig. 25. Mount the return air enthalpy sensor in

the leturn air duct. See Fig. 40. Wiring is provided in the

EconoMiSer IV wiring harness. See Fig. 32. The outdoor en-

thalpy changeover set point is set with the outdoor enthalpy set

point potentiometer on the EconoMiSer IV controllel: When

using this mode of changeover control, turn the enth_flpy set-

point potentiometer fully clockwise to the D setting.

Indoor Air Quality (IAQ) Sensor Input -- The IAQ input

can be used for demand control ventilation control based on the

level of CO 2 measured in the space or return air duct.

Mount the accessory IAQ sensor according to manufacturer

specifications. The IAQ sensor should be wired to the AQ and

AQI terminals of the controllel: Adjust the DCV potentiome-

ters to correspond to the DCV voltage output of the indoor air

qu_dity sensor fit the user-determined set point. See Fig. 43.

If a separate field-supplied transformer is used to power the

IAQ sensol: the sensor must not be grounded or the

EconoMiSer IV control bo_ud will be &imaged.

DAMPER VOLTAGE FOR MAX VENTILATION RATE

Fig. 43 -- C02 Sensor Maximum Range Setting

Exhaust Set Point Adjustment -- The exhaust set point will

determine when the exhaust fan runs based on dmnper position

(if accessory power exhaust is installed). The set point is modi-

fied with the Exhaust Fan Set Point (EXH SET) potentiometer

See Fig. 38. The set point represents the damper position above

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 unnecessary fan overload.

Minimum Position Control -- There is a minimum damper

position potentiometer on the EconoMiSer [V controllel: See

Fig. 38. 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

(To x l-Tiff) + (TR x l-Tiff) = 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 _dr

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 factory-installed jumper is in place across

terminals P and PI. If remote damper positioning is being

used, make sure that the terminals are wired according to

Fig. 32 and that the minimum position potentiometer is

turned fully clockwise.

4. Connect 24 vac across terminals TR and TRI.

5. Carelhlly adjust the minimum position potentiometer

until the measured supply air temperature matches the

calculated value.

6. Reconnect the supply-air sensor to terminals T and Tl.

Remote control of the EconoMiSer IV damper is desirable

when requiring additiomfl tempormy ventilation. If a

field-supplied remote potentiometer (Honeywell part number

$963B1128) is wired to the EconoMiSer IV controllek the

minimum position of the damper can be controlled from a re-

mote location.

To control the minimum damper position remotely, remove

the factory-installed jumper on the P and PI terminals on the

EconoMiSer IV controllel: Wire the field-supplied potentiome-

ter to the P and PI terminals on the EconoMi$er IV controller.

See Fig. 42.

Damper Movement -- Damper movement trom full open to

full closed (or vice versa) takes 2112minutes.

Thermostats -- The EconoMi$er 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

EconoMi$er 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 factoUdefault configuration for

the EconoMi$er IV control is occupied mode. Occupied status

is provided by the black jumper fiom terminal TR to terminal

N. When unoccupied mode is desired, inst_dl a field-supplied

timeclock function in place of the jumper between TR and N.

See Fig. 32. 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

EconoMi$er 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 air

Typically the maximum ventilation rate will be about 5 to

10% morn than the typical cfin 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 Ustrategy

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 CO 2 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-Tiff) + (TR x l-Tiff) = 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. 43

to determine the maximum setting of the CO 2 sensol: For ex-

ample, a 1100 ppm set point relates to a 15 cfm per person de-

sign. Use the 1100 ppm curve on Fig. 43 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 CO 2 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 the enthalpy is high. [n most cases, the norln_fl

heating and cooling processes are morn than adequate to re-

move the humidity loads for most commerci_fl applications.

If normal rooftop heating and cooling operation is not ade-

quate for the outdoor humidity level, an energy recovery unit

and/or a dehumidification option should be considered.

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

just evaporator-fan speed to meet jobsite conditions. Tables 7A

and 7B show fan rpm at motor pulley settings for standard and

_flternate motors. See Table 8 and Fig. 44 for accessory and op-

tion static pressure diops. See Tables 9A and 9B for evaporator

fan motor performance. Refer to Tables 10-23 to determine fan

speed settings. Fan motor pulleys are factory set for speed

shown in Table 1.

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

speed will provide an acceptable air temperature rise range on

heating as shown in Table 1.

To change fan speed:

1. Shut offunit power supply.

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

Fig. 45 and 46.

3. Ix_osen movable pulley flange setscrew (see Fig. 47).

4. Screw movable flange toward fixed flange to increase fan

speed and away from fixed flange to decrease fan speed.

Increasing fan speed increases load on motol: 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

lull turn of pulley flange.)

To align fan and motor pulleys:

1. Ix_osen fan pulley setscrews.

2. Slide fan pulley along fan shaft.

3. Make anguhu" alignment by loosening motor from

mounting plate.

To adjust belt tension:

1. Ix_osen fan motor mounting nuts.

2. Si'..e 008 -- Slide motor mounting plate away from fan

scroll for proper belt tension (l/2-in. deflection with one

linger) and tighten mounting nuts (see Fig. 45).

Sizes 009-014 -- Slide motor mounting plate downward

to tighten belt tension. Secure motor mounting plate nuts.

See Fig. 46.

3. Adjust bolt and nut on mounting plate to secure motor in

fixed position.
