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.

![](asset-2.png)
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.

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

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.

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
![](asset-1e.png)
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.

![](asset-31.png)
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.

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

ch_uging procedure.
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.
Example: (Fig. 48)
Outdoor Temperature .............................. 85 F
Suction Pressure ............................... 80 psig
Suction Temperature should be ...................... 77 F
