SAFETY CONSIDERATIONS

Installation and servicing ah-conditioning equipment can be

hazardous due to system pressure and electrical components.

Only tlained and qualified service personnel should install,

repair, or service air-conditioning equipment.

Untrained personnel can pedorm 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 ah-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 _dl brazing operations.

Before performing service or maintenance operations on

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

tag on disconnect. Ensure voltage listed on unit &Lta plate

agrees with electrical supply provided for the unit. Electri-

cal shock could cause serious personal injury.

INSTALLATION

Unit is shipped in the vertical dischguge configuration. To

convert to horizontal configuration, remove screws from side

duct opening covers and remove covers. Using the same

screws, install covers on vertical duct openings with the

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, not to unit.

If electric or control power is to be routed through rite basepan,

attach the accessory thru-the-bottom service connections to the

basepan in accor&mce with the accessory installation instruc-

tions. Connection must be installed b@re unit is set on roof

(_rb.

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 _dso result in air leaks and poor unit

pedbrmance.

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

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

Refer to Accessory Roof Curb Installation Instructions for

additional infomtation as required.

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

Catalog No. 04-53500010-01 Printed in U,SA. Form 50T-5SI Pg 1 9-05 Replaces: 50T-3SI

SLAB MOUNT (Horizontal Units Only) -- Provide a level

conclete slab that extends a minimum of 6 in. beyond unit

cabinet. [nst_dl 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 file curb or

a&_pter cannot be used, support the unit with sleepers using the

curb or adapter support area. If sleepel.s ctmnot be used, sup-

poll 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 _fll

ducts to roof curb and building structure on vertical discharge

units. Do not connect dm_'ork to unit. For horizontal applica-

tions, field-supplied flanges should be attached to horizontal

discharge openings and all ductwork should be attached to the

flanges. Insulate and weatherproof all extern_d 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 requiled around ductwoN.

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

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

economizel:

Step 3 -- Install External Trap for Condensate

Drain -- The unit's 3/4-in. condensate drain connections are

located at the bottom and side of the unit. Unit discharge

connections do not determine the use of &'ain connections;

either drain connection can be used with vertical or horizont;fl

applications.

When using the standard side drain connection, make sure

the red plug in the alternate bottom connection is tight before

inst;dling the unit.

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

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

connection to file side connection. See Fig. 4. The piping for

the condensate drain and external trap can be completed after

the unit is in place. Tile center drain plug looks like a star

connection, howevek it can be removed with a l/2-in, socket

drive extension.

All units must have an extern;d trap for condensate drain-

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

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

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

use a pipe size sm;dler than the unit connection (3/4-in.). See

Fig. 5.

Step 5 -- 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_wed for electrical gl_mnd when

installed in accordance with NEC (National Electrical

Code), ANSI/NFPA (American Natiomd Standards

Institute/National Fire Protection Association), latest

edition (in Cana&L, Canadian Electrical Code CSA

[Canadian Standards Association] C22.1 ), and local electri-

cal codes. Ftdlure to follow this warning could result in the

installer being liable for pel_onal 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 from 230-v l/4-in, spade terminal and connecting it to

200-v V4-in. spade terminal of transformel_

See Tables 2A and 2B. Refer to unit label diagram for

additional information. Pigtails are pl_wided for field wire con-

nections. Use factou-supplied splices or UL (Undel_ritel_'

Laboratories) approved copper/aluminum connectol_

When inst_dling units, provide a disconnect per NEC.

All field wiring must comply with the NEC and local

requirements.

Inst_dl field wiring as follows:

1. Inst_dl conduit through side panel openings. For units

without electric heat, install conduit between disconnect

and contl_l box.

2. Inst_dl power lines to terminal connections as shown in

Fig. 8.

Power wiring leads are located inside power wiring access

panel.

FIELD CONTROL WIRING -- Install a CmTier-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 aver-

age temperature in accordance with thermostat installation

instructions. Connect thermostat wires to terminal board.

Route thermostat cable or equiv¢dent single leads of colored

wire from subbase terminals to low-voltage connections on

unit (shown in Fig. 9).

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

Wile Gage) insulated wire (35 Cminimum). For 50 to 75 ft,

use no. 16 AWG insulated wire (35 Cminimum). For over

75 fl, use no. 14 AWG insulated wire (35 Cminimum). All

wire lmger 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 wiles 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. 10. The laceway provides the UL

required clearance between high- and low-voltage wiling.

NOTE: If thin-the-bottom power connections are used refer to

the accessory installation instructions for information on power

wiring. Refer to Fig. 6A and 6B for &illing holes in basepan.

IMPORTANT: Optiomfl factory-installed, _flternate

evaporator-fan motors are not available for 50TFF,

NOTES:

1. In compliance with NEC requirements for multimotor and combination load equipment (refer to

NEC Articles 430 and 440), the overeurrent protective device for the unit shall be fuse or HACR

breaker. Canadian units may be fuse or circuit breaker.

2. Unbalanced 3-Phase Supply Voltage

Never operate a motor where a phase imbalance in supply voltage ts greater than 2% Use the

following formula to determine the percent of voltage imbalance.

% Voltage Imbalance

= 1OO x max voltage deviation from average voltage

average voltage

Example: Supply voltage is 460-3-60.

AB = 452 v

AB C BC = 464 v

(_ AC = 455 v

Average Voltage = 452 + 464 + 455

3

1371

3

= 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.

7

% Voltage Imbalance = 100 x --457

= 1.53%

This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%.

I IMPORTANT: If the supply voltage phase imbalance is more than 2%, contact your local I

electric utility company immediately. I

3. For units with power exhaust: If a single power source is to be used, size wire to include

power exhaust MCA and MQCR Check MCA and MOCP when power exhaust is powered

through the unit (must be in accordance with NEC 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 50TFF0O6--5 unit with MCA = 28.9 and MOCP = 35, with

CRPWREXHO30AO0 power exhaust.

MCA New = 28.9 amps + 1.6 amps = 30.5 amps

If the new MCA does not exceed the published MOCk then MOCP would not change. The

MOCP in this example is 35 amps, the MCA New is below 35, therefore the MOCP is accept-

able. If "MCA New" is larger than the published MOCP, raise the MOCP to the next larger

size. For separate power, the MOCP for the power exhaust will be 15 amps per NEC.

NOTES:

1. In compliance with NEC requirements for multimotor and combination load equipment (refer to

NEC Articles 430 and 440), the overcurrent protective device for the unit shall be fuse or HACR

breaker. Canadian units may be fuse or circuit breaker.

2. Unbalanced 3-Phase Supply Voltage

Never operate a motor where a phase imbalance in supply voltage is greater than 2% Use the

following formula to determine the percent of voltage imbalance.

% Voltage Imbalance

= 100 x max voltage deviation from average voltage

average voltage

Example: Supply voltage is 460-3-60.

AB = 452 v

AB C BC = 464v

AC = 455 v

Average Voltage = 452 + 464 + 455

3

1371

3

= 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.

7

% Voltage Imbalance = 100 x --

457

= 1.53%

This amount of phase imbalance is satisfactory as it is below the maximunl allowable 2%.

I IMPORTANT: If the supply voltage phase imbalance is more than 2%, contact your local I

electric utility company immediately. I

3. For units with power exhaust: 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 (must be in accordance with NEC 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 50TFFO06--5 unit with MCA = 28.9 and MOCP = 35, with

CRPWREXHO3OAO0 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

MOCP in this example is 35 amps, the MCA New is below 35, therefore the MOCP is accept-

able. If "MCA New" is larger than the published MOCP, raise the MOCP to the next larger

size. For separate power, the MOCP for the power exhaust will be 15 amps per NEC.

1. In compliance with NEC requirements for multimotor and combination load equipment (refer to

NEC Articles 430 and 440), the overcurrent protective device for the unit shall be fuse or HACR

breaker. Canadian units may be fuse or circuit breaker.

2. Unbalanced 3-Phase Supply Voltage

Never operate amotor where aphase imbalance in supply voltage is greater than 2% Use the

following formula to determine the percent of voltage imbalance.

% Voltage imbalance

= 100 x max volta[le deviation from average voltage

average voltage

Example: Supply voltage is 460-3-60.

AB = 452 v

AB C BC = 464v

AC = 455 v

Average Voltage = 452 + 464 + 455

3

1371

=-- 3

=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.

7

% Voltage imbalance = 100 x 45_

= 1.53%

This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%.

I IMPORTANT: If the supply voltage phase imbalance is more than 2%, contact your local I

electric utility company immediately. I

3. For units with power exhaust: 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 (must be in accordance with NEC 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 50TFFO06---5 unit with MCA = 28.9 and MOCP = 35, with

CRPWREXHO3OAO0 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

MOCP in this example is 35 amps, the MCA New is below 35, therefore the MOCP is accept-

able. If "MCA New" is larger than the published MOCP, raise the MOCP to the next larger

size. For separate power, the MOCP for the power exhaust will be 15 amps per NEC.

NOTES:

1. In compliance with NEC requirements for muffimotor and combination load equipment (refer to

NEC Articles 430 and 440), the overcurrent protective device for the unit shall be fuse or HACR

breaker. Canadian units may be fuse or circuit breaker.

2. Unbalanced 3-Phase Supply Voltage

Never operate a motor where a phase imbalance in supply voltage ts greater than 2% Use the

following formula to determine the percent of voltage imbalance.

% Voltage hnbalance

= 100 x max voltage deviation from average voltage

average voltage

Example: Supply voltage is 460-3-60.

AB = 452 v

AS C BC = 464 v

_) AC = 455 v 452 + 464 + 455

Average Voltage = 3

1371

3

= 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.

7

% Voltage Imbalance = 100 x --457

= 1.53%

This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%.

I IMPORTANT: If the supply voltage phase imbalance is more than 2%, contact your local

electric utility company immediately. I

3. For units with power exhaust: 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 (must be in accordance with NEC 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 50TFFOO6m5 unit with MCA = 28.9 and MOCP = 35, with

CRPWREXHO3OAO0 power exhaust.

MCA New = 28.9 amps + 1.6 amps = 30.5 amps

If the new MCA does not exceed the published MOCR then MOCP would not change. The

MOCP in this example is 35 amps, the MCA New is below 35, therefore the MOCP is accept-

able. ff "MCA New" is larger than the published 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.

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.

7

% Voltage Imbalance = 100 x 45_

= 1.53%

This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%.

JIMPORTANT: If the supply voltage phase imbalance is more than 2%, contact your local J

electric utility company immediately. I

3. For units with power exhaust: 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 (must be in accordance with NEC 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 50TFFO06---5 unit with MCA = 28.9 and MOCP = 35, with

CRPWREXHO30AO0 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

MOCP in this example is 35 amps, the MCA New is below 35, therefore the MOCP is accept-

able. If "MCA New" is larger than the published MOCP, raise the MOCP to the next larger

size. For separate power, the MOCP for the power exhaust will be 15 amps per NEC.

PREMIERLINK rM CONTROL -- Tile PremierLink control-

let is compatible with Career Comfort Network® (CCN)

devices. This control is designed to allow usel5 file access and

ability to change factory-defined settings, thus expanding the

function of the stan&trd unit control board. CmTier's diagnostic

standard tier display tools such as Navigator TM or Scrolling

Marquee can be used with the PremierLink contmfler.

The PremierLink contmfler (see Fig. 15A and 15B) requires

the use of a Canier electronic thermostat or a CCN connection

for time broadcast to initiate its intermfl fimeclock. This is

necessary for broadcast of time of day functions (occupied/

unoccupied). No sensors am supplied wifli the field-mounted

PremierLink control. The factory-installed PmmierLink con-

trol includes only file supply-air temperature (SAT) sensor and

the outdoor air temperature ((-)AT) sensor as standard. An

indoor air qutflity (CO2) sensor can be added as tin option.

Refer to Table 3 for sensor usage_ Refer to Fig. 16 for

PremierLink controller wiring. The PmmierLink control may

be mounted in the control panel or an area below the control

panel.

NOTE: PremierLink controller versions 1.3 and later me

shipped in Sensor mode. If used with a thennostat, the

PremierLink controller must be configured to Thermostat mode.

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

the unit is supplied with a factou-mounted PremierLink con-

trol, the supply-air temperature (SAT) sensor (33ZCSENSAT)

is factou-supplied and wired. The wiring is muted fl_)m the

PremierLink control over the control box, through a grommet,

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

along the fan deck over to file 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 I/_-in. hole in the flange or duct.

Use two field-supplied, self-diilling screws to secure the sensor

probe in a horizontal orientation.

NOTE: The sensor must be mounted in the discharge airstream

downstream of file 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 (OAT) Sensor -- When the unit is

supplied with a factou-mounted PremierLink control, the

outdoor-air temperature sensor (OAT) is factou-supplied and

wimdi

Install the Indoor Air Quality (CO2'_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 CO 2 sensol:

Wire the CO 2 sensor to the COM and IAQI terminals of J5

on the PremierLink controller Refer to the PremierLink [nstal-

lation, 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 accesso Uto be

used with the economizer damper control option. The outdoor

air enthalpy sensor is part of the enthalpy control. The separate

field-installed accessory return mr enthalpy sensor

(HH57AC078) is required for differential enthalpy control.

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

diffemnfial 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 diy contact switch input to the PremierLink control-

lel: Locate the controller in place of an existing economizer

controller or near the actuatol: The mounting plate may not be

needed if existing bracket is used.

A closed contact indicates that outside air is prefened to the

return ail: An open contact indicates that the economizer

should remain at minimum position.

ECONOMISER IV STANDARD SENSORS

Outdoor Air Temperature (OAT) Sensor -- The outdoor air

temperature sensor (HH57AC074) is a 10 to 20 mA device

used to measme the outdoor-air temperature. The outdoor-air

temperature is used to determine when the EconoMiSer IV can

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

EconoMiSer IV in the outdoor airstream. See Fig. 19. The

operating range of temperature measurement is 40 to 100 E

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. 31. This sensor is factory installed. The

operating range of temperature measurement is 0 ° to 158 E See

Table 4 for sensor temperatme/resistance values.

The temperature sensor looks like an eyelet terminal with

wires running to it. The sensor is located in the "crimp end"

and is sealed from moisture.

Outdoor Air Lockout Sensor -- The EconomiSer IV is

equipped with an mnbient temperature lockout switch located

in the outdoor air stream which is used to lockout the compres-

sors below a 42 F ambient temperature. See Fig. 19.

ECONOMI$ER IV CONTROL MODES

IMPORTANT: Tile optional EconoMiSer2 does not

include a controllel: The EconoMiSer2 is operated by a 4 to

20 mA signal from an existing field-supplied controller

(such as PremierLink TM control). See Fig. 27 for wiring

information.

Determine tile EconoMiSer IV control mode befole set up of

the control. Some modes of operation may requile diffelent sen-

sors. Refer to Ntble 5. The EconoMiSer IV is supplied from the

factory 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 c_m be added to allow for different types

of changeover control and operation of the EconoMiSer IV and

unit.

Outdoor Dry Bulb Changeover -- The stan&_rd controller is

shipped from the factory configured for outdoor dry bulb

changeover control. The outdoor air and supply air temperature

sensors are included as stan&_rd. For this control mode, the

outdoor temperature is compmed 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 dampel.s will

be controlled to provide free cooling using outdoor all: 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. 32. The scale on the potentiometer is A,

B, C, and D. See Fig. 33 for the conesponding temperature

changeover values.

Differential Dry Bulb Control -- For differenti_d @ bulb

control the stan_lard outdoor dry bulb sensor is used in conjunc-

tion with an additiomd accessory @ bulb sensor (part number

CRTEMPSN002A00). The accessory sensor must be mounted

in the return airstream. See Fig. 34. Wiring is provided in the

EconoMiSer IV wiring harness. See Fig. 26.

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 set point poten-

tiometer fully clockwise to the D setting. See Fig. 32.

Outdoor Enthalpy Changeover -- For enthalpy control, ac-

cessory enthalpy sensor (part number HH57AC078) is re-

quired. Replace the stan&_rd outdoor dry bulb temperature sen-

sor with the accessory enthalpy sensor in the same mounting

location. See Fig. 19. When the outdoor air enthalpy rises

above the outdoor enthalpy changeover set point, the outdoor-

tdr dmnper moves to its minimum position. The outdoor

enthalpy changeover set point is set with the outdoor enthalpy

set point potentiometer on the EconoMiSer IV controllec The

set points are A, B, C, and D. See Fig. 35. The factory-installed

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

on the EconoMiSer IV controllel: See Fig. 19 and 36.

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 return air duct. The EconoMiSer IV

controller compares the outdoor air enthalpy to the return air

enth_dpy 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 enth_dpy than

the return ail, the EconoMiSer IV opens to bring in outdoor air

for free cooling.

Replace the standard outside air dry bulb temperature sen-

sor with the accessory enthalpy sensor in the same mounting

location. See Fig. 19. Mount the return air enth_dpy sensor in

the return _dr duct. See Fig. 34. Wiring is provided in the

EconoMi$er IV wiring hmness. See Fig. 26. The outdoor en-

thalpy changeover set point is set with the outdoor enthalpy set

point potentiometer on the EconoMiSer IV controller. When

using this mode of changeover control, turn the enthalpy 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 controller Adjust the DCV potentiome-

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

quality sensor at the user-determined set point. See Fig. 37.

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

[AQ sensor, the sensor must not be grounded or the

EconoMiSer IV control board will be dmnaged.

Exhaust Set Point Adjustment -- The exhaust set point will

determine when the exhaust fan runs based on &_mper position

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

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

See Fig. 32. 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 allows the &tmper to reach the appro-

priate position to avoid unnecessary fan overload.

Minimum Position Control -- There is a minimum &tmper

position potentiometer on the EconoMiSer IV controllel: See

Fig. 32. The minimum dmnper position maintains the mini-

mum airflow into the building during the occupied period.

When using demand ventilation, the minimum damper 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 _llow the

minimum amount of outdoor air. as requiled by local codes, to

enter the building. Make minimum position adjustments with

at least 10 F temperature difference between the outdoor and

leturn-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 1---_ ) + (TR x 1---_-_-) = T M

To = Outdoor-Air Temperature

OA = Percent of Outdoor Air

T R= Return-Air Telnperature

RA = Percent of Return Air

T M= Mixed-Air Temperature

As an example, if local codes require 10% outdoor air

during occupied conditions, outdoor-air temperature is

60 IF.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. [f remote dmnper positioning is being

used, make sure that the terminals are wired according to

Fig. 26 and that the minimum position potentiometer is

turned fully clockwise.

4. Connect 24 vac across terminals TR and TRI.

5. Carefully adjust the minimum position potentiometer

until the measured mixed-air temperature matches the

calculated value.

6. Reconnect the supply air sensor to terminals T and TI.

Remote control of the EconoMiSer IV dmnper is desirable

when requiring additional temporary ventilation. If a

field-supplied remote potentiometer (Honeywell Dut number

$963B1128) is wired to the EconoMiSer IV controller, the

minimum position of the damper can be controlled fi_m 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 EconoMiSer IV controllel:

See Fig. 36.

Damper Movement -- Damper movement from full open to

lull closed (or vice versa) takes 21/2 minutes.

Thermostats -- The EconoMiSer IV control works with con-

ventional thermostats that have a YI (cool stage 1), Y2 (cool

stage 2), WI (heat stage 1), W2 (heat stage 2), and G (fan). The

EconoMi$er [V control does not support space temperature

sensors. Connections me made at the themlostat terminal con-

nection board located in the main control box.

Occupancy Control -- The factory default configuration for

the EconoMiSer IV control is occupied mode. Occupied status

is provided by the black jumper from terminal TR to terminal

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

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

See Fig. 26. When the timeclock contacts are closed, the

EconoMiSer IV control will be in occupied mode. When the

timeclock contacts are open (removing the 24-v signal from

terminal N), the EconoMiSer IV will be in unoccupied mode.

Demand Controlled Ventilation (DCV) -- When using the

EconoMi$er IV for demand controlled ventilation, there me

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 cal-

culated to provide the desired fresh ail:

29

Typically tile maximum ventilation rate will be about 5 to

10_ ,more than the typical cfm required per pe_on, using

normal 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 lequired ventilation rate

for maximum occupancy. A proportional-anticipatory strategy

will cause tile fresh air supplied to increase as the room CO2

level increases even though the CO 2 set point has not been

reached. By the time the CO 2 level reaches 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, first detemfine file damper voltage out-

put for minimum or base ventilation. Base ventilation is the

ventilation required to remove contaminants 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 thele should be at least a

10 degree difference in outside and leturn-air temperatures.

OA RA

(Tox 1-]"_) +(TRx I'T_)=TM

To = Outdoor-Air Temperature

OA = Percent of Outdoor Air

TR = Return-Air Temperature

RA = Percent of Return Air

T M= Mixed-Air Temperature

Once base ventilation has been detemfined, set the mini-

mum dmnper 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 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-

httion rate of 20% (or base plus 15 cfln per person). Use Fig. 37

to determine the maximum setting of the CO 2 sensor For ex-

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

sign. Use the 1100 ppm curve on Fig. 37 to find the point when

the CO 2 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

EconoMiSer IV controller will output the 6.7 volts from the

CO 2 sensor to the actuator when the CO 2 concentration in the

space is at 1100 ppm. The DCV set point may be left at 2 volts

since the CO 2 sensor voltage will be ignored by the

EconoMiSer IV controller until it rises above the 3.6 volt set-

ting of the minimum position potentiometel:

Once the fully occupied dmnper position has been deter-

mined, set ti3e maximum dalnper demand control ventilation

potentiometer to this position. Do not set to the maximum posi-

tion as this can result in over-ventilation to the space and poten-

tial high-humidity levels.

CO, Sensor Configuration -- The CO 2sensor has preset

standard voltage settings timt can be selected anytime after the

sensor is powered up. See Table 6.

Use setting 1 or 2 for Carrier equipment. See Table 6.

1. Press Clear and Mode buttons. Hold at least 5 seconds

until the sensor enters the Edit mode.

The custom settings of the CO 2sensor can be changed any-

time after the sensor is energized. Follow the steps below to

change file non-stan&trd settings:

1. Press Clear and Mode buttons. Hold at least 5 seconds

until the sensor enters the Edit mode.

2. Press Mode twice. The STDSET Menu will appem:

3. Use the Up/Down button to toggle to the NONSTD menu

and press Entel:

4. Use the Up/Down button to toggle through each of the

nine variables, starting with Altitude, until file desired set-

ting is reached.

5. Press Mode to move through the variables.

6. Press Enter to lock in the selection, then press Mode to

continue to the next vmiable.

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 recovely 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 normal

heating and cooling processes am morn than adequate to m-

move the humidity loads for most commemial 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.

PRE-START-UP

F;filure to observe the following warnings could result in

serious personal injuu:

1. Follow recognized safety practices and wear protective

goggles when checking or servicing refrigerant system.

2. Do not operate compressor or provide any electric

power to unit unless compressor terminal cover is in

place and secured.

3. Do not remove compressor terminal cover until all

electrical sources are disconnected.

4. Relieve all pressure from system before touching or

disturbing anything inside compressor termimd box if

refiigerant leak is suspected around compressor ter-

minals. Use accepted methods to recover refiigerant.

5. Never attempt to repair soldered connection while re-

fiigerant system is under pressure.

6. Do not use torch to remove any component. System

contains oil and refiigerant under pressure. To remove

a component, wear protective goggles and proceed as

follows:

a. Shut off electrical power to unit.

b. Recover refiigerant to relieve all pressure from

system using both high- and low-pressure ports.

c. Cut component connection tubing with tubing

cutter, and remove component from unit.

d. Carefully unsweat remaining tubing stubs

when necessary. Oil can ignite when exposed

to torch flame.

Proceed as follows to inspect and prepale the unit for initkd

st_ut-up:

1. Remove all access panels.

2. Read and follow instructions on _dl WARNING.

CAUTION, and INFORMATION labels attached to (or

shipped) with unit.

3. Make the following inspections:

a. Inspect for shipping and handling damages such

as broken lines, loose parts, or disconnected wires.

b. Inspect for oil at all refrigerant tubing connections

and on unit base. Detecting oil generally indicates

a refrigerant leak. Leak-test all refrigerant tubing

connections using electronic leak detector, halide

torch, or liquid-soap solution.

c. Inspect all field-wiring and factory-wiring con-

nections. Be sure that connections are completed

and tight. Ensure no electrical wiring is in contact

with refrigerant tubing or sharp edges.

d. Inspect coil fins. If damaged during shipping and

handling, carefully straighten fins with a fin comb.

4. Verify the following conditions:

a. Make sure that condenser-fan blades are correctly

positioned in fan orifice. Refer to Condenser-Fan

Adjustment section on page 52 for more details.

b. Make sure that air filters are in place.

c. Make sure that condensate drain trap is filled with

water to ensure proper drainage.

d. Make sure that all tools and miscellaneous loose

parts have been removed.

START-UP

Unit Preparation- Make sure that unit has been in-

stalled in accordance with inst;_llation instructions and applica-

ble codes.

Return-Air Filters- Make sure correct filters ale in-

stalled in unit (see Tables IA and IB). Do not operate unit

without return-air filters.

Compressor Mounting- Compressors are internally

spring mounted. Do not loosen or remove compressor hold-

down bolts.

Internal Wiring- Check all electric_d connections in

unit control boxes; tighten as requiled. Ensure wiring does not

come in contact with sharp metal edges.

Refrigerant Service Ports -- To service refrigerant

service ports, remove access panel. Each unit system has

4 Schrader-type service ports: one on the suction line, one on

the liquid line, and two on the compressor discharge line.

Be sure that caps on the ports are tight. The Schmder-type

valve that is located under the high-pressure switch does not

have a Schrader core.

High Flow Refrigerant Valves -- Two high flow

valves are located on the hot gas tube coming out of the

compressor and the suction tube going into the compressol:

L;uge black plastic caps identify these valves with O-rings

inside screwing the cap and onto a brass body. No field access

to these wdves is available at this time. Ensure the plastic caps

remain on the valves and are tight or the possibility of refriger-

ant leakage could occm:

Compressor Rotation-- On 50TFF,TM007 scroll

compressor units, it is important to be certain compressor is

rotating in the proper direction. To determine whether or not

compressor is rotating in the proper direction:

1. Connect service gages to suction and discharge pressure

fittings.

2. Energize the compressol:

3. The suction pressure should diop and the discharge

pressure should rise, as is normal on any start-up.

If the suction pressure does not diop and the discharge

pressure does not rise to norlnal levels:

1. Note that the evaporator fan is probably _dso rotating in

the wrong direction.

2. Turn off power to the unit. Install lock-out tag.

3. Reverse any two of the unit power leads.

4. Reapply power to the unit.

The suction and discharge pressme levels should now move

to their normal start-up levels.

NOTE: When the compressor is rotating in the wrong direc-

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

provide cooling.

Cooling- Set space therlnostat to OFF position. Set

system selector switch at COOL position and fan switch at

AUTO. position. Adjust thermostat to a setting below room

temperature. Complessor st;uts on closure of contactoc

Check cooling effects at a setting below room temperature.

Check unit charge. Refer to Refrigerant Charge section,

page 52.

Reset thermostat at a position above room temperature.

Compressor will shut off.

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

position. Resetting thermostat at a position above room

temperature shuts unit off tempor_uily until space temperature

exceeds thermostat setting.

Safety Relief- A soft solder joint in tile suction line at

the low-pressure sel-vice port provides pressure relief under

abnormal temperature and pressure conditions.

Ventilation (Continuous Fan) -- Set fan and systeln

selector switches at ON and OFT positions, respectively.

Evaporator fan operates continuously to provide constant air

circulation.

Operating Sequence

COOLING. UNITS WITHOUT ECONOMIZER -- When

thermostat calls 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

starts. The outdoor-fan motor runs continuously while unit is

cooling.

HEATING, UNITS WITHOUT ECONOMIZER -- Upon a

request for heating from the space therlnostat, terminal WI will

be energized with 24 v. The IFC and heater contactor (HCI)

are energized.

COOLING, UNITS WITH ECONOMISER IV -- When free

cooling is not available, the complessors will be controlled by

the zone thermostat. When flee cooling is available, the

outdoor-air dmnper is modulated by the EconoMi$er IV

control to provide a 50 to 55 F supply-air temperatme into the

zone. As the supply-air temperatme fluctuates above 55 or be-

low 50 E the &_mpers will be modulated (open or close) to

bring the supply-air tempemtme back within the set point limits.

Integrated EconoMi$er IV operation on single-stage units re-

quires a 2-stage thennostat (YI and Y2).

For EconoMi$er IV operation, there must be a therlnostat

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 E then the outdoor-air cklmper posi-

tion will be lully closed. If the supply-air temperature contin-

ues to fall, the outdoor-air dmnper will close. Control returns to

normal 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 accesso UCO 2 sensors are connected to the

EconoMiSer IV control, a demand controlled ventilation strate-

gy will begin to operate. As the CO,_ level in the zone increases

above the CO2 set point, the minimum position of the &_mper

will be increased proportionally. As the CO 2 level decreases

because of the inclease in fresh all: the outdoor-air damper will

be proportionally closed. Dmnper position will follow the high-

er demand condition from DCV mode or free cooling mode.

Damper movement from full closed to lull open (or vice

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

If fiee cooling can be used as determined fiom the appropri-

ate changeover command (switch, dUbulb, enthalpy curve,

diffelential dUbulb, or differential enthalpy), a call for cooling

(YI closes at the thermostat) will cause the control to modulate

the &impels open to maintain the supply air temperature set

point at 50 to 55 E

As the supply-air temperature diops below the set point

range of 50 to 55 E the control will modulate the outdoor-air

dampers closed to maintain the proper supply-air temperature.

HEATING, UNITS WITH ECONOMISER IV -- When the

room telnperature 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

damper moves to the minimum position.

COOLING. UNITS WITH ECONOMISER2, PREMIER-

LINK TM CONTROL AND A THERMOSTAT -- When free

cooling is not available, the compressols will be controlled by

the PremierLink control in response to the YI and Y2 inputs

from the thermostat.

The PremierLiuk 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.

• Euthalpy must be LOW (may be jumpered if an euthalpy

sensor not available).

• Economizer position is NOT forced.

Pre-cooling occurs when the is no call from the therlnostat

except (3. Pie-cooling is defined as the economizer modulates

to provide 70 F supply ;tic

When fiee cooling is available the PremierLiuk control will

control the compressors and economizer to provide a supply-

;fir 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 ale 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.

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

economizer will go to minimum position for 3 minutes or

until SAT > 68 E

• 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-installed accessory CO 2 sensors ;ue connected to the

PremierLink 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

cklmper will be increased proportionally. As the CO 2 level

decreases because of the increase in fresh ;fir, the outdoor-air

&_mper will be proportionally closed.

49

HEATINGUNITSWITHECONOMISER2,PREMIER-

LINKTM CONTROL AND A THERMOSTAT -- When the

thermostat calls for heating, termimfl WI is energized. The

PremierLink control will move the economizer damper to the

minimum position if there is a call for G and closed if there is a

call for W 1without Ca.The IFC and heater contactor (HC 1) tue

energized.

When the thermostat is satisfied and WI is deenergized, the

IFM stops after a 45-second time-off delay unless G is still

maintainedi

COOLING. UNITS WITH ECONOMI$ER2, 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 c_dcula-

tion as indicated by Fig 40.

The PremierLink controller will use the following informa-

tion to deterraine 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 tv.

• 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 damper is

positioned through the use of a Proportional Integral (PID)

control process to provide a calculated supply-air temperature

into the zone. The supply air will maintain the space tempera-

ture between the heating and cooling set points as indicated in

Fig. 41.

The PremierLink controller will integrate the compressoLs

stages with the economizer based on similar 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-

pare space temperature and space set point.

When outside-air temperature conditions require the econo-

mizer to close for a compressor stage-up sequence, the econo-

mizer control integrator is reset to zero after the stage-up se-

quence is completed. This prevents the supply-air temperature

from diopping 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 the economizer space set point is a

c_dculated 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. 41.

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

dmnper moves to minimum position. The operating sequence

is complete. The ECSR is recalculated every 30 seconds.

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

dmnper opens and closes, the power exhaust fans will be

energized and deenergized.

If field-installed accessory CO 2 sensors gue connected to

the PremierLink TM control, a PID-controlled demand ventila-

tion strategy will begin to operate. As the CO2 level in the 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 ECONOMI$ER2, PREMIERLINK

CONTROL AND A ROOM SENSOR -- EveU40 seconds

the controller will calculate the required heat stages (maximum

of 3) to maintain supply-air temperature (SAT) if the following

qualifying conditions am met:

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

• COOL mode is not active.

• OCCUPIED, TEMP.COMPENSATED START or HEAT

mode is active.

• SAT reading is available.

• Fire shutdown mode is not active.

If all of the above conditions gue met, the number of heat

stages is c_dculated; otherwise the required number of heat

stages will be set to 0.

If the PremierLink controller determines that heat stages am

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

NO CHARGE -- Use standard evacuating techniques. After

ew_cuating system, weigh in the specified amount of refriger-

ant. (Refer to Tables IA and lB.)

LOW CHARGE COOLING -- Use Cooling Ch;u'ging Charts,

Fig. 46-49. Vary refrigerant until the conditions of the appropri-

ate chart am met. Note the charging chart is different from type

norm_dly used. Chmt is based on chalging the units to the cor-

rect superheat for the vtuious operating conditions. Accurate

pressure gage and temperature sensing device ;ue required.

Connect the pressure gage to the service port on the suction

line. Mount the temperature sensing device on the suction line

and insulate it so that outdoor ambient temperature does not

affect the reading. Indoor-air cfln must be within the normal

operating range of the unit.

TO USE COOLING CHARGING CHART- Take the out-

door ambient temperature and read the suction pressure gage.

Refer to appropriate chart to determine what suction tempera-

ture should be. If suction temperature is high, add refrigerant. If

suction temperature is low, carelidly recover some of the

chtuge. Recheck the suction pressure as charge is adjusted.
