SAFETY CONSIDERATIONS

Installation and servicing of air-conditioning equipment can be

hazardous due to system pressure and electrical components.

Only trained and qualified service personnel should install, repair,

or service air-conditioning equipment.

Untrained personnel can perform basic maintenance functions of

cleaning coils and filters and replacing filters. All other operations

should be performed by trained service personnel. When working

on air-conditioning equipment, observe precautions 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.

Recognize safety information. This is the safety--alert symbol

. When you see this symbol on the furnace and in

instructions or manuals, be alert to the potential for personal

injury.

Understand the signal words DANGER, WARNING, and

CAUTION. These words are used with the safety--alert symbol.

DANGER identifies the most serious hazards which will result in

severe personal injury or death. WARNING signifies a hazard

which could result in personal injury or death. CAUTION is used

to identify unsafe practices which may result in minor personal

injury or product and property damage. NOTE is used to

highlight suggestions which will result in enhanced installation,

reliability, or operation.

ELECTRICAL SHOCK HAZARD

Failure to follow this warning could cause personal

injury or death.

Before performing service or maintenance operations

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

lockout tag. Ensure electrical service to rooftop unit

agrees with voltage and amperage listed on the unit

rating plate.

!WARNING

FIRE, EXPLOSION HAZARD

Failure to follow this warning could death and/or

property damage.

Disconnect gas piping from unit when leak testing at

pressure greater than 1/2psig. Pressures greater than 1/2

psig will cause gas valve damage resulting in hazardous

condition. If gas valve is subjected to pressure greater than

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

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

less, a unit connected to such piping must be isolated by

manually closing the gas valve(s).

!WARNING

INSTALLATION

Unit is shipped in the vertical discharge configuration. To convert

to horizontal discharge application, remove duct opening covers.

Using the same screws, install covers on duct openings in

basepan of unit with insulation-side down. Seals around

openings must be tight. (See Fig. 1.)

C06108

Fig. 1 --- Horizontal Conversion Panels

Step 1 —Provide Unit Support

ROOF CURB

Assemble and install accessory roof curb in accordance 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. If electric control power

or gas service 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.

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

IMPORTANT: The gasketing of the unit to the roof curb is critical

for a watertight seal. Install gasket supplied with the roof curb as

shown in Fig. 2. Improperly applied gasket can result in air leaks and

poor 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 required.

SLAB MOUNT (Horizontal Units Only)

Provide a level concrete slab that extends a minimum of 6 in.

beyond unit cabinet. Install a gravel apron in front of

condenser-coil air inlet to prevent grass and foliage from

obstructing airflow.

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

required.

ALTERNATE UNIT SUPPORT

When the curb or adapter cannot be used, support unit with

sleeper rails using unit curb or adapter support area. 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

discharge units. Do not connect ductwork to unit. For horizontal

applications, field-supplied isolation flanges should be attached to

horizontal discharge 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

accordance with applicable codes.

Ducts passing through an unconditioned space must be insulated

and covered with a vapor barrier.

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

ducted through the roof deck to comply with applicable fire

codes.

A minimum clearance is not required 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 economizer.

These units are designed for a minimum continuous return-air

temperature in heating of 50_F (dry bulb), or an intermittent

operation down to 45_F (dry bulb), such as when used with a

night setback 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_F. Indoor

comfort may be compromised when these lower air temperatures

are used with insufficient heating temperature 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 connections do not

determine the use of drain connections; either drain connection

can be used with vertical or horizontal applications.

When using the standard side drain connection, ensure the plug

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

the unit.

To use the bottom drain connection for a roof curb installation,

relocate the factory-installed plug (Red) from the bottom

connection to the side connection. The center drain plug looks

like a star connection, however it can be removed with a 1/2-in.

socket drive extension. (See Fig. 4.) The piping for the

condensate drain and external trap can be completed after the unit

is in place.

All units must have an external trap for condensate drainage.

Install a trap 4-in. deep and protect against freeze-up. If drain line

is installed downstream from the external trap, pitch the line away

from the unit at 1 in. per 10 ft of run. Do not use a pipe size

smaller than the unit connection (3/4in.). (See Fig. 5.)

Step 4 —Rig and Place Unit

Inspect unit for transportation damage, and file any claim with

transportation agency. Keep unit upright and do not drop.

Spreader bars are not required if top crating is left on unit, and

rollers may be used to move unit across a roof. Level by using

unit frame as a reference. See Table 1 and 2 and Fig. 6 for

additional information. Operating weight is shown in Table 1 and

2 and Fig. 6.

ELECTRICAL SHOCK HAZARD

Failure to follow this warning could result in personal

injury or death.

Unit cabinet must have an uninterrupted, unbroken

electrical ground to minimize the possibility of personal

injury if an electrical fault should occur. This ground may

consist of electrical wire connected to unit ground lug in

control compartment, or conduit approved for electrical

ground when installed in accordance with NEC (National

Electrical Code), ANSI/NFPA (National Fire Protection

Association), latest edition, and local electrical codes. Do

not use gas piping as an electrical ground.

!WARNING

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 from the 230-v terminal on the

transformer and connecting it to the 200-v terminal from the

transformer.

Refer to unit label diagram for additional information. Pigtails

are provided for field service. Use factory-supplied splices or UL

(Underwriters’ Laboratories) approved copper connector.

When installing units, provide a disconnect per NEC.

All field wiring must comply with NEC and local

requirements.

Install conduit through side panel openings indicated in Fig. 8.

Route power lines through connector to terminal connections as

shown in Fig. 12.

Voltage to compressor terminals during operation must be within

voltage range indicated on unit nameplate (also see Tables 3 and

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

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

Tables 3 and 4, Note 3 to determine the percent voltage

imbalance. Operation on improper line voltage or excessive phase

imbalance constitutes abuse and may cause damage to electrical

components. Such operation would invalidate any applicable

Carrier warranty.

NOTE: If accessory thru-the-bottom connections and roof curb

are used, refer to the Thru-the-Bottom Accessory Installation

Instructions for information on power wiring and gas connection

piping. The power wiring, control wiring and gas piping can be

routed through field-drilled holes in the basepan. The basepan is

specially designed and dimpled for drilling the access connection

holes.(SeeFig.2.)

field control wiring

Install a Carrier-approved accessory thermostat assembly

according to installation instructions included with the accessory.

Locate 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 subbase terminals through connector on unit to low-voltage

connections (shown in Fig. 13 and 14).

Connect thermostat wires to matching screw terminals of

low-voltage connection board. (See Fig. 13 and 14.)

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

Wire Gauge) insulated wire (35_Cminimum).For50to75ft,use

no. 16 AWG insulated wire (35_C minimum). For over 75 ft, use

no. 14 AWG insulated wire (35_C minimum). All wire larger

than no. 18 AWG cannot be directly connected to the thermostat

and will require a junction box and splice at the thermostat.

Pass the control wires through the hole provided in the corner

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. 15). The raceway provides the UL required clearance

between high and low-voltage wiring.

premierlink control

The PremierLink controller is compatible with Carrier Comfort

NetworkR(CCN) devices. This control is designed to allow

users the access and ability to change factory--defined settings,

thus expanding the function of the standard unit control board.

Carrier’s diagnostic standard tier display tools such as

Navigatortor Scrolling Marquee can be used with the

PremierLink controller.

The PremierLink controller (see Fig. 24 and 25) requires the use

of a Carrier electronic thermostat or a CCN connection for time

broadcast to initiate its internal timeclock. This is necessary for

broadcast of time of day functions (occupied/unoccupied). No

sensors are supplied with the field--mounted PremierLink control.

The factory--installed PremierLink control includes only the

supply--air temperature (SAT) sensor and the outdoor air

temperature (OAT) sensor as standard. An indoor air quality

(CO2) sensor can be added as an option. Refer to Table 5 for

sensor usage. Refer to Fig. 26 for PremierLink controller wiring.

The PremierLink control may be mounted in the control panel or

an area below the control panel.

NOTE: PremierLink controller versions 1.3 and later are shipped

in Sensor mode. If used with a thermostat, the PremierLink

controller must be configured to Thermostat mode.

Install the Supply Air Temperature (SAT) Sensor

When the unit is supplied with a factory--mounted PremierLink

control, the supply--air temperature (SAT) sensor

(33ZCSENSAT) is factory--supplied and wired. The wiring is

routed from the PremierLink control over the control box,

through a grommet, into the fan section, down along 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 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 discharge 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 Air Temperature Sensor (OAT)

When the unit is supplied with a factory-mounted PremierLink

control and economizer, the outdoor-air temperature sensor

(OAT) is factory-supplied and wired.

Install the Indoor Air Quality (CO2)Sensor

Mount the optional indoor air quality (CO2) sensor according to

manufacturer specifications.

A separate field-supplied transformer must be used to power the

CO2sensor.

Wire the CO2sensor to the COM and IAQI terminals of J5 on the

PremierLink controller. Refer to the PremierLink Installation,

Start-up, and Configuration Instructions for detailed wiring and

configuration information.

Enthalpy Sensors and Control

The enthalpy control (HH57AC077) is supplied as a

field-installed accessory to be used with the EconoMi$er2

damper control option. The outdoor air enthalpy sensor is part of

the enthalpy control. The separate field-installed accessory return

air enthalpy sensor (HH57AC078) is required for differential

enthalpy control.

NOTE: The enthalpy control must be set to the “D” setting for

differential enthalpy control to work properly.

The enthalpy control receives the indoor and return

enthalpy from the outdoor and return air enthalpy sensors and

provides a dry contact switch input to the PremierLink controller.

Locate the controller in place of an existing economizer controller

or near the actuator. The mounting plate may not be needed if

existing bracket is used.

A closed contact indicates that outside air is preferred to the

return air. An open contact indicates that the economizer should

remain at minimum position.

Outdoor Air Enthalphy Sensor/Enthalpy Controller

(HH57AC077)

To wire the outdoor air enthalpy sensor, perform the following (See

Fig. 27 and 28):

NOTE: The outdoor air sensor can be removed from the back of

the enthalpy controller and mounted remotely.

ECONOMI$ER IV STANDARD SENSORS

Outdoor Air Temperature (OAT) Sensor

The outdoor air temperature sensor (HH57AC074) is a 10 to 20 mA

device used to measure the outdoor-air temperature. The outdoor-air

temperature is used to determine when the EconoMi$er IV can be

used for free cooling. The sensor is factory-installed on the

EconoMi$er IV in the outdoor airstream. (See Fig. 29.) The

operating range of temperature measurement is 40_to 100_F.

48HE,HJ

Supply Air Temperature (SAT) Sensor

The supply air temperature sensor is a 3 K thermistor located at

the inlet of the indoor fan. (See Fig. 41.) This sensor is factory

installed. The operating range of temperature measurement is 0

to 158_F. See Table 6 for sensor temperature/resistance values.

Outdoor Air Lockout Sensor

The Economi$er IV is equipped with an ambient temperature

lockout switch located in the outdoor air stream which is used to

lockout the compressors below a 42_F ambient temperature. (See

Fig. 29.)

ECONOMI$ER IV CONTROL MODES

IMPORTANT: The optional EconoMi$er2 does not include a

controller. The EconoMi$er2 is operated by a 4 to 20 mA signal

from an existing field-supplied controller (such as PremierLink

control). See Fig. 37 for wiring information.

Determine the EconoMi$er IV control mode before set up of the

control. Some modes of operation may require different

sensors. Refer to Table 7. The EconoMi$er IV is supplied from

the factory with a supply--air temperature sensor and an outdoor--

air temperature sensor. This allows for operation of the

EconoMi$er 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 EconoMi$er IV and unit.

Outdoor Dry Bulb Changeover

The standard controller is shipped from the factory configured for

outdoor dry bulb changeover control. The outdoor--air and

supply--air temperature sensors are included as standard. For this

control mode, the outdoor temperature is compared to an

adjustable set point selected on the control. If the outdoor-air

temperature is above the set point, the EconoMi$er 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

dampers will be controlled to provide free cooling using outdoor

air. When in this mode, the LED next to the free cooling set point

potentiometer will be on. The changeover temperature set point is

controlled by the free cooling set point potentiometer located on

the control. (See Fig. 42.) The scale on the potentiometer is A, B,

C, and D. See Fig. 43 for the corresponding temperature

changeover values.

Differential Dry Bulb Control

For differential dry bulb control the standard outdoor dry bulb

sensor is used in conjunction with an additional accessory dry

bulb sensor (part number CRTEMPSN002A00). The accessory

sensor must be mounted in the return airstream. (See Fig. 44.)

Wiring is provided in the EconoMi$er IV wiring harness. (See

Fig. 36.)

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

compared to the return-air temperature and the lower temperature

airstream is used for cooling. When using this mode of

changeover control, turn the enthalpy setpoint potentiometer fully

clockwise to the D setting. (See Fig. 42.)

Outdoor Enthalpy Changeover

For enthalpy control, accessory enthalpy sensor (part number

HH57AC078) is required. Replace the standard outdoor dry bulb

temperature sensor with the accessory enthalpy sensor in the same

mounting location. (See Fig. 29.) 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 EconoMi$er IV controller. The set

points are A, B, C, and D. (See Fig. 45.) The factory-installed

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

on the EconoMi$er IV controller. (See Fig. 29 and 46.)

48HE,HJ

Differential Enthalphy Control

For differential enthalpy control, the EconoMi$er IV controller

uses two enthalpy sensors (HH57AC078 and

CRENTDIF004A00), one in the outside air and one in the return

air duct. The EconoMi$er IV controller compares the outdoor

air enthalpy to the return air enthalpy to determine EconoMi$er

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 EconoMi$er IV opens to

bring in outdoor air for free cooling.

(See Fig. 29.) Mount the return air enthalpy sensor in the return

air duct. (See Fig. 44.) Wiring is provided in the EconoMi$er IV

wiring harness. (See Fig. 36.) The outdoor enthalpy changeover

set point is set with the outdoor enthalpy set point potentiometer

on the EconoMi$er IV controller. When using this mode of

changeover control, turn the enthalpy setpoint 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 CO2measured 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

AQ1 terminals of the controller. Adjust the DCV potentiometers

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

sensor at the user-determined set point. (See Fig. 47.)

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

sensor, the sensor must not be grounded or the EconoMi$er IV

control board will be damaged.

Exhaust Set Point Adjustment

The exhaust set point will determine when the exhaust fan runs

based on damper position (if accessory power exhaust is

installed). The set point is modified with the Exhaust Fan Set

Point (EXH SET) potentiometer. (See Fig. 42.) The set point

represents the damper position above which the exhaust fans will

be turned on. When there is a call for exhaust, the EconoMi$er IV

controller provides a 45 15 second delay before exhaust fan

48HE,HJ

activation to allow the dampers to open. This delay allows the

damper to reach the appropriate position to avoid unnecessary fan

overload.

Minimum Position Control

There is a minimum damper position potentiometer on the

EconoMi$er IV controller. (See Fig. 42.) The minimum damper

position maintains the minimum airflow into the building during

the occupied period.

When using demand ventilation, the minimum damper position

represents the minimum ventilation position for VOC (volatile

organic compound) ventilation requirements. The maximum

demand ventilation position is used for fully occupied ventilation.

When demand ventilation control is not being used, the minimum

position potentiometer should be used to set the occupied

ventilation position. The maximum demand ventilation position

should be turned fully clockwise.

Adjust the minimum position potentiometer to allow the

minimum amount of outdoor air, 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:

(TOx

OA )+(TRxRA )=T

100 100

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 air during

occupied conditions, outdoor-air temperature is 60_F, and

return-air temperature is 75_F.

(60 x .10) + (75 x .90) = 73.5_F

2. Disconnect the supply air sensor from terminals T and T1.

3. Ensure that the factory-installed jumper is in place across

terminals P and P1. If remote damper positioning is being

used, make sure that the terminals are wired according to

Fig. 36 and that the minimum position potentiometer is

turned fully clockwise.

4. Connect 24 vac across terminals TR and TR1.

5. Carefully adjust the minimum position potentiometer

until the measured supply air temperature matches the

calculated value.

6. Reconnect the mixed air sensor to terminals T and T1.

Remote control of the EconoMi$er IV damper is desirable when

requiring additional temporary ventilation. If a

field-supplied remote potentiometer (Honeywell part number

S963B1128) is wired to the EconoMi$er IV controller, the

minimum position of the damper can be controlled from a remote

location.

To control the minimum damper position remotely, remove the

factory-installed jumper on the P and P1 terminals on the

EconoMi$er IV controller. Wire the field-supplied potentiometer

to the P and P1 terminals on the EconoMi$er IV controller. (See

Fig. 46.)

Damper Movement

Damper movement from full open to full closed (or vice versa)

takes 21/2minutes.

Thermostats

The EconoMi$er IV control works with conventional thermostats

that have a Y1 (cool stage 1), Y2 (cool stage 2), W1 (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 terminal connection board located in the

main control box.

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.

Typically the maximum ventilation rate will be about 5 to 10%

more than the typical cfm required per person, using normal

outside air design criteria.

Demand Controlled Ventilation (DCV)

When using the EconoMi$er IV for demand controlled

ventilation, there are some equipment selection criteria which

should be considered. When selecting the heat capacity and cool

capacity of the equipment, the maximum ventilation rate must be

evaluated for design conditions. The maximum damper position

must be calculated to provide the desired fresh air.

A proportional anticipatory strategy should be taken with the

following conditions: a zone with a large area, varied occupancy,

and equipment that cannot exceed the required ventilation rate at

design conditions. Exceeding the required ventilation 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-anticipatory strategy will cause the

fresh air supplied to increase as the room CO2level increases

even though the CO2set point has not been reached. By the time

the CO2level reaches the set point, the damper will be at

maximum ventilation and should maintain the set point.

In order to have the CO2sensor control the economizer damper in

this manner, first determine the damper voltage output for

minimum or base ventilation. Base ventilation is the ventilation

required to remove contaminants during unoccupied 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.

(TOx

OA )+(TRxRA )=T

100 100

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 minimum

damper position potentiometer to the correct position.

The same equation can be used to determine the occupied or

maximum ventilation rate to the building. For example, an output

of 3.6 volts to the actuator provides a base ventilation rate of 5%

and an output of 6.7 volts provides the maximum ventilation rate

of 20% (or base plus 15 cfm per person). Use Fig. 44 to

determine the maximum setting of the CO2sensor. For example,

a 1100 ppm set point relates to a 15 cfm per person design. Use

the 1100 ppm curve on Fig. 47 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 CO2sensor should be 1800 ppm. The

EconoMi$er IV controller will output the 6.7 volts from the CO2

sensor to the actuator when the CO2concentration in the space is

at 1100 ppm. The DCV set point may be left at 2 volts since the

CO2sensor voltage will be ignored by the EconoMi$er IV

controller until it rises above the 3.6 volt setting of the minimum

position potentiometer.

Once the fully occupied damper position has been determined, set

the maximum damper demand control ventilation potentiometer

to this position. Do not set to the maximum position as this can

result in over-ventilation to the space and potential high-humidity

levels.

Dehumidification of Fresh Air with DCV Control

Information 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 reduce the moisture content of the fresh air being

brought into the building when the enthalpy is high. In most

cases, the normal heating and cooling processes are more than

adequate to remove the humidity loads for most commercial

applications.

If normal rooftop heating and cooling operation is not adequate

for the outdoor humidity level, an energy recovery unit and/or a

dehumidification option should be considered.

Step 9 —Adjust Evaporator--Fan Speed

Adjust evaporator-fan speed to meet jobsite conditions.

Tables 9 and 10 show fan rpm at motor pulley settings. Tables 11

and 15 show maximum amp draw of belt-drive motor. Table 14

shows sound data. Refer to Tables 16-35 for performance data.

See Table 36 for accessory static pressure drop. See Fig. 48 for

the Humidi-MiZersystem static pressure drops.

Belt drive motors

Fan motor pulleys are factory set for speed shown in Table 1 or 2.

Check pulley alignment and belt tension prior to start-up.

To change fan speed:

1. Shut off the unit power supply and tag disconnect.

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

(See Fig. 49.)

3. Loosen movable pulley flange setscrew. (See Fig. 50.)

4. Screw movable flange toward fixed flange to increase

speed and away from fixed flange to decrease speed.

Increasing fan speed increases load on motor. Do not

exceed maximum speed specified in Table 1 or 2.

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

tighten setscrew. (See Table 1 or 2 for speed change for

each full turn of pulley flange.)

6. Adjust belt tension and align gan and motor pulleys per

guidance below.

To align fan and motor pulleys, loosen fan pulley setscrews and

slide fan pulley along fan shaft. Make angular alignment by

loosening motor from mounting.

Additional motor and fan alignment, as well as angular alignment

can be made by loosening the four motor mounting bolts from

the mounting plate.

To adjust belt tension:

1. Loosen the two motor mounting nuts as shown in Fig. 49.

Some models may have a third mounting nut located on

the opposite side of the fan motor mounting plate.

2. Slide motor mounting plate away from fan scroll for

proper belt tension (1/2-in.deflectionwith8to10lbof

force) and tighten mounting nuts.

3. Adjust lock bolt and nut on mounting plate to secure

motor in fixed position.
