SAFETY CONSIDERATIONS
Installation and servicing of air-conditioning equipment can
be hazardous due to system pressure and electrical compo-
nents. Only trained and qualified service personnel should
install, repair, or service air-conditioning equipment.
Untrained personnel can perform basic maintenance func-
tions of cleaning coils and filters and replacing filters. All other
operations should be performed by trained service personnel.
When working on air-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 extinguisher available for all brazing operations.
INSTALLATION
Unit is shipped in the vertical discharge configuration. To
convert to horizontal configuration, remove horizontal duct
opening covers. Using the same screws, install covers on duct
openings in basepan of unit with the insulation-side down.
Seals around duct openings must be tight.
Step 1 — Provide Unit Support
ROOF CURB — Assemble and install the accessory roof
curb in accordance with instructions shipped with the curb.
See Fig. 1. Install insulation, cant strips, roofing felt, and
counter flashing as shown. Ductwork must be attached to the
curb, not to the unit. If electric or control power is to be routed
through the basepan, be sure to choose the appropriate acces-
sory kit. See Fig. 1. Attach the accessory thru-the-bottom ser-
vice connections to the basepan and roof curb in accordance
with the accessory installation instructions. Connections must
be installed before the unit is set on the roof curb.
The roof curb should be level. This is necessary for the unit
drain to function properly. Unit leveling tolerances are shown
in Fig. 2. Refer to Accessory Roof Curb Installation Instruc-
tions for additional information, as required.
Before performing service or maintenance operations on
unit, turn off main power switch to unit and tag disconnect.
Ensure voltage listed on unit data plate agrees with electri-
cal supply provided for the unit. Electrical shock could
cause serious personal injury.
IMPORTANT: The gasketing of the unit to the roof curb
is critical for watertightness. Install gasket supplied with
the roof curb as shown in Fig. 1. Improperly applied
gasket can also result in air leaks and poor unit
performance.

SLAB MOUNT (Horizontal Units Only) — Provide a level
concrete slab that extends a minimum of 6 in. beyond the unit
cabinet. Install a gravel apron in front of the condenser coil air
inlet to prevent grass and foliage from obstructing airflow.
NOTE: Horizontal units may be installed on a roof curb if
required.
ALTERNATE UNIT SUPPORT — When the curb or
adapter cannot be used, support unit with sleepers using unit
curb or adapter support area. If sleepers cannot be used, sup-
port the long sides of the unit with a minimum of 3 equally
spaced 4-in. x 4-in. pads on each side.
Step 2 — Field Fabricate Ductwork — Secure all
ducts to the roof curb and building structure on vertical dis-
charge units. Do not connect ductwork to the unit. For horizon-
tal applications, field-supplied flanges should be attached to
horizontal discharge openings and all ductwork should be at-
tached to the flanges. Insulate and weatherproof all external
ductwork, joints, and roof openings with counterflashing and
mastic in accordance with applicable codes.
Ducts passing through an unconditioned space must be
insulated and covered with a vapor barrier.
If a plenum return is used on a vertical unit, the return
should be ducted through the roof deck to comply with applica-
ble fire codes.
A minimum clearance is not required around ductwork.
Cabinet return-air static pressure (a negative condition) should
not exceed 0.35 in. wg with economizer or 0.45 in. wg without
economizer.
Step 3 — Install Condensate Drain Line and
External Trap — Condensate drain connections are locat-
ed on the bottom and side of the unit. Unit discharge connec-
tions do not determine the use of drain connections; either
drain connection can be used with vertical or horizontal dis-
charge units.
When using the standard side drain connection, make sure
the plug in the alternate bottom connection is tight before
installing the unit.
To use the bottom drain connection for a roof curb installa-
tion, relocate the factory-installed plug from the bottom con-
nection to the side connection. The center drain plug looks like
a star connection, but can be removed using a 1/2-in. socket
drive extension. See Fig. 3. The piping for the condensate drain
and external trap can be completed after the unit is in place.
All units must have an external trap for condensate drain-
age. Install a trap at least 4 in. deep and protect against freeze-
up. If the drain line is installed downstream from the external
trap, pitch the line away from the 50TFQ unit at 1/4in. per ft of
run. Do not use a pipe size smaller than the unit connection.
See Fig. 4.
Step 4 — Rig and Place Unit — Inspect the unit for
transportation damage, and file any claim with the transporta-
tion agency. Keep the unit upright and do not drop it. Spreader
bars are not required if top crating is left on the unit, and rollers
may be used to move the unit across a roof. Level by using the
unit frame as a reference. See Table 1 and Fig. 5 for additional
information. Operating weight is shown in Table 1 and Fig. 5.
Lifting holes are provided in base rails as shown in Fig. 5
and 6. Refer to rigging instructions on the unit.
POSITIONING — Maintain clearance around and above the
unit to provide proper airflow and service access. See Fig. 6.
A properly positioned unit will have the following clearanc-
es: 1/4-in. clearance between the roof curb and base rails on
each side and front of the unit; 1/4-in. clearance between the
roof curb and rear of unit. (See Fig. 1, section C-C.)
Do not install the unit indoors. Do not locate the unit air in-
lets near exhaust vents or other sources of contaminated air.
Although the unit is weatherproof, guard against water from
higher level runoff and overhangs.
After the unit is in position, remove the polyethylene ship-
ping wrapper and top crating.
All panels must be in place when rigging. Unit is not
designed for handling by a fork truck. Damage to unit may
result.

Step 5 — Make Electrical Connections
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 will be connected to a 208-v power sup-
ply, the transformer must be rewired by disconnecting the
black wire from the 230-v terminal on the transformer and
connecting it to the 200-v terminal from the transformer.
Refer to the unit label diagram for additional information.
Pigtails are provided for field wire connections. Use factory-
supplied splices or a UL (Underwriters’ Laboratories)
approved copper/aluminum connector.
When installing units, provide a disconnect per the
NEC. All field wiring must comply with the NEC and local
requirements.
Install field wiring as follows:
1. Install conduit through the side panel openings. For units
without electric heat, install conduit between the discon-
nect and control box.
2. Install power lines to terminal connections as shown in
Fig. 7.
3. For units with electric heat, refer to Table 2 and Accessory
Electric Heat Installation Instructions.
During operation, voltage to compressor terminals must be
within the range indicated on the unit nameplate (also see
Tables 3A and 3B). On 3-phase units, voltages between phases
must be balanced within 2% and the current within 10%. Use
the formula shown in Tables 3A and 3B and Note 2, on page 12
to determine the percentage of voltage imbalance. Operation
on improper line voltage or excessive phase imbalance consti-
tutes abuse and may cause damage to electrical components.
Such operation invalidates any applicable Carrier warranty.
NOTE: If the unit is mounted on a roof curb and the electrical
power will be run up “thru-the-bottom,” be sure to choose the
proper accessory kit shown in Fig. 1. This kit, available from
your local distributor, ensures a reliable watertight connection.
Refer to the thru-the-bottom accessory installation instructions
for information on wiring the unit.
Unit cabinet must have an uninterrupted, unbroken electri-
cal ground to minimize the possibility of personal injury if
an electrical fault should occur. This ground may consist of
electrical wire connected to unit ground lug in control com-
partment, or conduit approved for electrical ground when
installed in accordance with NEC (National Electrical
Code), ANSI/NFPA (American National Standards Insti-
tute/National Fire Protection Association) 70 (latest year),
and local electrical codes. Failure to follow this warning
could result in the installer being liable for personal injury
of others.

Table 2 — Electric Heating Capacities
*Two heater packages required to provide kW indicated.
†Use CRSINGLE004A00 for units with convenience outlet.
**Use CRSINGLE005A00 for units with convenience outlet.
††Use CRSINGLE002A00 for units with convenience outlet.
***Use CRSINGLE002A00 for units with high-static motor
and convenience outlet.
NOTES:
1. The rated heater voltage is 240 and 480 v. If power distribution voltage varies from rated heater voltage, heater kW will vary accordingly.
2. To determine heater kW at voltages other than those shown in table, use the following formula:
Heater kW new =Heater kW rated x (unit power distribution voltage/rated heater voltage)2
As an example:
For a 16 kW heater rated at 240 v with a power distribution voltage of 215 v
kW new =16 kW (215/240)2
kW new =12.8 kW (rating at 215 v)

*Heaters are field installed only.
†Used to determine minimum disconnect size per NEC.
**Heater capacity (kW) is based on heater voltage of 208 v, 240 v and 480 v.
If power distribution voltage to unit varies from rated heater voltage, heater
kW will vary accordingly.
††Fuse or HACR circuit breaker.
***Optional disconnect switch is unavailable.
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.
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 volt-
age imbalance.
%Voltage Imbalance
Example: Supply voltage is 460-3-60.
AB =452 v
BC =464 v
AC =455 v
Determine maximum deviation from average voltage.
(AB) 457 – 452 =5v
(BC) 464 – 457 =7v
(AC) 457 – 455 =2v
Maximum deviation is 7 v.
Determine percent of voltage imbalance.
%Voltage Imbalance =100 x
=1.53%
This amount of phase imbalance is satisfactory as it is below the maximum
allowable 2%.

*Heaters are field installed only.
†Used to determine minimum disconnect size per NEC.
**Heater capacity (kW) is based on heater voltage of 208 v, 240 v and 480 v.
If power distribution voltage to unit varies from rated heater voltage, heater
kW will vary accordingly.
††Fuse or HACR circuit breaker.
***Optional disconnect switch is unavailable.
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.
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 volt-
age imbalance.
%Voltage Imbalance
Example: Supply voltage is 460-3-60.
AB =452 v
BC =464 v
AC =455 v
Determine maximum deviation from average voltage.
(AB) 457 – 452 =5v
(BC) 464 – 457 =7v
(AC) 457 – 455 =2v
Maximum deviation is 7 v.
Determine percent of voltage imbalance.
%Voltage Imbalance =100 x
=1.53%
This amount of phase imbalance is satisfactory as it is below the maximum
allowable 2%.

FIELD CONTROL WIRING — Install a Carrier-approved
accessory thermostat assembly according to installation
instructions included with the accessory. Locate the thermostat
assembly on a solid wall in the conditioned space to sense aver-
age temperature.
NOTE: If using a Carrier electronic thermostat, set the thermo-
stat configuration for “non-heat pump operation.” This family
of products does not require an O terminal to energize the
reversing valve.
Route the thermostat cable or equivalent single leads of
colored wire from the subbase terminals to the low-voltage
connections on the unit (shown in Fig. 8 and 9) as described in
Steps 1 through 3 below.
NOTE: For wire runs up to 50 ft, use no. 18 AWG (American
Wire Gage) insulated wire (35 C minimum). For 50 to 75 ft,
use no. 16 AWG insulated wire (35 C minimum). For over
75 ft, use no. 14 AWG insulated wire (35 C minimum). All
wire larger than no. 18 AWG cannot be directly connected to
the thermostat and will require a junction box and splice at the
thermostat.
1. Connect the thermostat wires to the screw terminals of
the low voltage connection board.
2. Pass the control wires through the hole provided in the
corner post.
3. Feed the wire 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 raceway provides the UL-
required clearance between the high-voltage and low-
voltage wiring.
DEFROST BOARD — The defrost board timer is set for a
30 minute defrost cycle from the factory. To adjust to a 50 or
90 minute cycle, remove the wire connected to the 30 minute
quick connect on the defrost board. See Fig. 11. Connect the
lead to the 50 or 90 minute quick connect on the defrost board,
depending on the application.
HEAT ANTICIPATOR SETTINGS — Set the first-stage
heat anticipator setting at 0.8 and set the second-stage heat
anticipator setting at 0.3.

purposes. The disconnect switch is only available for limited
applications. See electrical data tables on pages 10-15 for dis-
connect switch usage.
CONVENIENCE OUTLET — An optional convenience out-
let provides power for rooftop use. For maintenance personnel
safety, the convenience outlet power is off when the unit dis-
connect is off. Adjacent unit outlets may be used for service
tools. An optional “Hot Outlet” is available from the factory as
a special order item.
NOVAR CONTROLS — Optional Novar controls (ETM 3051)
are available for replacement or new construction jobs.
MANUAL OUTDOOR-AIR DAMPER — The outdoor-air
hood and screen are attached to the basepan at the bottom of
the unit (for shipping).
Assembly:
1. Determine the amount of ventilation required for build-
ing. Record the amount for use in Step 8.
2. Remove the filter access panel by raising the panel and
swinging it outward. The panel is now disengaged from
the track and can be removed. No tools are required to
remove the filter access panel. Remove the outdoor-air
opening panel. Save the panels and screws. See Fig. 12.
3. Separate the hood and screen from the basepan by remov-
ing the screws and brackets securing them. Save all
screws and discard the brackets.
4. Replace the outdoor air opening panel.
5. Place the hood on the front of the outdoor air opening
panel. See Fig. 13 for hood details. Secure the top of the
hood with the 6 screws removed in Step 3. See Fig. 14.
6. Remove and save the 8 screws (4 on each side) from the
sides of the manual outdoor-air damper.
7. Align the screw holes on the hood with the screw holes
on the side of the manual outdoor-air damper. See Fig. 13
and 14. Secure the hood with the 8 screws from Step 6.
8. Adjust the minimum position setting of the damper blade
by adjusting the manual outdoor-air adjustment screws on
the front of the damper blade. See Fig. 12. Slide the blade
vertically until it is in the appropriate position determined
by Fig. 15. Tighten the screws.
9. Remove and save the screws currently on the sides of
hood. Insert the screen. Secure the screen to the hood us-
ing the screws. See Fig. 14.

PREMIERLINK™ CONTROL — The PremierLink control-
ler is compatible with Carrier Comfort Network® (CCN) de-
vices. This control is designed to allow users the access and
ability to change factory-defined settings, thus expanding the
function of the standard unit control board. Carrier’s diagnostic
standard tier display tools such as Navigator™ or Scrolling
Marquee can be used with the PremierLink controller.
The PremierLink controller (see Fig. 16 and 17) requires the
use of a Carrier electronic thermostat or a CCN connection for
time broadcast to initiate its internal timeclock. This is neces-
sary for broadcast of time of day functions (occupied/
unoccupied). No sensors are supplied with the field-mounted
PremierLink control. The factory-installed PremierLink con-
trol includes only the supply-air temperature (SAT) sensor and
the outdoor air temperature (OAT) sensor as standard. An in-
door air quality (CO2) sensor can be added as an option. Refer
to Table 4 for sensor usage. Refer to Fig. 18 for PremierLink
controller wiring. The PremierLink control may be mounted in
the control panel or an area below the control panel.
NOTE: PremierLink controller versions 1.3 and later are
shippedinSensormode.Ifusedwithathermostat,thePre-
mierLink controller must be configured to Thermostat mode.
Install the Supply Air Temperature (SAT) Sensor —When
the unit is supplied with a factory-mounted PremierLink con-
trol, the supply-air temperature (SAT) sensor (33ZCSENSAT)
is factory-supplied and wired. The wiring is routed from the
PremierLink control over the control box, through a grommet,
into the fan section, down along the back side of the fan, and
along the fan deck over to the supply-air opening.
The SAT probe is wire-tied to the supply-air opening (on the
horizontal opening end) in its shipping position. Remove the
sensor for installation. Re-position the sensor in the flange of
the supply-air opening or in the supply air duct (as required by
local codes). Drill or punch a 1/2-in. hole in the flange or duct.
Use two field-supplied, self-drilling screws to secure the sensor
probe in a horizontal orientation.
NOTE: The sensor must be mounted in the discharge airstream
downstream of the cooling coil and any heating devices. Be
sure the probe tip does not come in contact with any of the unit
or heat surfaces.
Outdoor Air Temperature (OAT) Sensor — When the unit is
supplied with a factory-mounted PremierLink control, the
outdoor-air temperature (OAT) sensor is factory-supplied and
wired.
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 CO2sensor.
Wire the CO2sensor to the COM and IAQI terminals of J5
on the PremierLink controller. Refer to the PremierLink Instal-
lation, Start-up, and Configuration Instructions for detailed
wiring and configuration information.
