Service and maintenance features result in low costs
Servicing and maintaining a rooftop
unit has never been easier with the
new factory-installed service features.
Hinged service access panels for the
filter/indoor-fan motor, compressors,
evaporator fan, and control box areas.
Quick access to major components is
accomplished by simply unlatching and
swinging open the various panels.
Each hinged panel is permanently
mounted to the unit, thereby eliminating the concern of a dropped or windblown panel puncturing delicate roof
materials. Tie downs are provided to
ensure panels remain in place when
open.
The indoor fan system slides out for
easy access. Blower wheels, motors,
belts, and both bearings can be serviced with ease.
ComfortLink controls provide temperature and pressure readings electronically. No gages are required.
An optional 115-v Ground Fault Interrupt (GFI) receptacle as a convenient
power source for drills, lights, refrigerant recovery units, or other electrical
service tools. The option includes a
step-down transformer, so only unit
power is required.
An optional, integral, non-fused disconnect switch within the rooftop unit
reduces installation time, labor and
material costs. The externally mounted
handle incorporates power lockout
capability to further protect service
personnel.
Indoor air quality begins with
Carrier rooftops
Internally sloped condensate pans
minimize biological growth in rooftop
units in accordance with ASHRAE
(American Society of Heating, Refrigeration, and Air Conditioning Engineers) Standard 62. Two-in. filters, optional 30% pleated filters, or optional
4-in. filter capability with optional dirty
filter indicator switch provide for greater particle removal in the return air.
Accessory enthalpy controls available
for use with the optional economizers
maximize building humidity control.
Built in capability for DCV (demand
control ventilation) is standard and integrates with CO2 sensors.

IS O
The 48/50HG rooftop unit replaces
an installed Carrier rooftop unit because it fits on an existing DP, DR, HJ,
or TJ roof curb. No transition curb is
required, therefore saving from 15 to
25% on installation cost is possible.
Dedicated vertical or side-by-side
horizontal airflow units can be ordered.
No clumsy, expensive adapter curbs
are required, saving installation cost.
The 48/50HG014-028 units fit one
size roof curb. The contractor can
order and install the roof curb early in
the construction stage, before decisions on size requirements are made.
Using the Carrier ComfortLink™
controls, an installation run test can
verify a proper start up.
All units feature base rail design with
rigging holes for easier maneuvering,
rigging, and lifting on the jobsite. Durable packaging protects all units during
shipment and storage.
The units can be ordered in either
the vertical or horizontal discharge
configurations. An accessory horizontal discharge kit is also available for
easy field conversion from a vertical to
a horizontal discharge configuration.
Convenient duct openings in the
unit basepans permit side-by-side or
concentric duct connections without
requiring internal unit modification.
Factory- and field-installed electric
heaters are available in a wide range of
capacities (50HG). Gas heat is available on 48HG units in 3 sizes.
Terminal boards, located in the base
unit control box, facilitate connections
to room thermostat, outdoor thermostat(s), economizer, and electric heat.
Hinged service panels are provided,
permitting easy access.
Thru-the-curb service connections
allow power and control wiring to be
routed through the curb, minimizing
roof penetrations. Both power and
control connections are made on the
same side of the unit to simplify installation. In addition, color-coded wires
permit easy tracing and diagnostics.

Durable, dependable
construction
Integrated economizers and
outdoor air
Designed for durability in any climate,
the weather-resistant cabinets are constructed of galvanized steel and all
exterior panels are coated with a
prepainted baked enamel finish. The
paint finish is non-chalking, and is capable of withstanding ASTM (American Society for Testing and Materials)
B117 500-hour Salt Spray Test. Totally enclosed condenser-fan motors and
permanently lubricated bearings provide additional unit dependability. The
shaft-down design of the condenser
fan also ensures protection from harsh
environments.
During a call for cooling, if the
outdoor-air temperature is below the
control changeover set point, the
ComfortLink™ unit control modulates
the economizer outdoor-air damper
open to achieve the set point. If
economizer cooling is not sufficient,
additional compressor stages are energized in addition to the economizer. If
the outdoor-air temperature is above
the changeover set point, the first
stage of compression is activated and
the economizer stays at minimum position. Economizer operation is controlled by a thermistor that senses
outdoor-air temperature. An accessory
(field-installed) differential enthalpy
switch upgrade kit is also available.
For units without economizer, yearround ventilation is enhanced by a
manual outdoor-air damper. The
damper can be preset to admit up to
50% outdoor air.
In addition, the barometric relief
damper or multi-stage power exhaust
can be utilized to help maintain proper
building pressure.
Quality and reliability
To assure long life and quality performance, every rooftop unit is factory
run tested. Individual components are
also tested at many levels to assure
than only the best parts make it into
the Carrier rooftop units. A printout
accompanies each unit, indicating the
pressure and temperature of the run
test.
Reliable scroll compressors are used
with three independent refrigerant circuits on the 016,020, and 024 units
and two independent circuits on the
014 and 028 units. Multiple circuits
provide better reliability at part load
conditions and on VVT® (Variable Volume and Temperature) installations.
Redundancy and backup operation is
assured with the multiple circuit design.
Each circuit features a TXV (thermostatic expansion valve) for refrigerant
metering with removable powerhead.
The Carrier Centurion units will operate in the cooling mode from 0° F to
125 F ambient temperature.
Highly reliable pillow-block bearings
are used in the indoor fan system.
Each circuit contains a liquid line filter drier.
The Carrier McMinnville, Tennessee
(U.S.A.) plant is an ISO 9001:2000
registered facility as are many of
Carrier’s other component and assembly plants throughout the world.
Quiet and efficient operation is
provided by belt-driven evaporator
fans. The belt-driven evaporator-fan
with variable-pitch pulleys allows
adjustment to available static pressure
to meet the job requirements of even
the most demanding applications.
Multiple drive options are available to
match system airflow and static pressure requirements.
Low sound
Outdoor sound levels of 8.2 bels (014024 units) and 8.5 bels (028 units) are
the best in the industry. Low sound
levels allow for maximum installation
flexibility.
Gas heating units
Integrated gas unit controller
(IGC) (48HG models) — All ignition
components are contained in the compact IGC which is easily accessible for
servicing. The IGC control board, designed and manufactured exclusively
for Carrier rooftop units, provides
built-in diagnostic capability. An LED
(light-emitting diode) simplifies troubleshooting by providing visual fault notification and system status confirmation.
The IGC also contains an anti-cycle
protection for gas heat operation. After 4 continuous cycles on the unit
high-temperature limit switch, the gas
heat operation is disabled, and an error
code is issued. This feature greatly improves reliability of the rooftop unit.
The IGC also contains burner control logic for accurate and dependable
gas ignition. This LED fault-notification
system reduces service person troubleshooting time and minimizes service
costs. The IGC can also maximize
heating efficiency by controlling evaporator fan on and off delays.
Efficient, dependable operation —
Tubular, dimpled gas heat exchangers
optimize heat transfer for improved efficiency. The tubular design permits
hot gases to make multiple passes
across the path of the supply air. The
dimpled design creates a turbulent gas
flow to maximize heating efficiency.
The extra thick Alumagard™ heat exchanger coating provides corrosion
resistance and ensures long life. An
optional stainless steel heat exchanger
is also available.
The unsightly appearance of flue
stacks is eliminated and the effects of
wind on heating operations are diminished by the induced draft combustion
system. The inducer fan draws hot
combustion gas through the heat exchanger at the optimum rate for the
most effective heat transfer. Induced
draft heating systems are safer than
positive pressure, forced draft heating
systems. With the induced draft heating system, the heat exchanger operates under negative pressure, preventing flue gas leakage into the indoor
supply air.
During the Heating mode, the
evaporator-fan relay automatically
starts the evaporator fan after the heat
exchanger warms up to a suitable
temperature. The 30-second fan delay
prevents cold air from entering the
supply duct system when the conditioned space is calling for heat to maximize efficiency.
The direct-spark ignition system
saves operating expense when compared to pilot ignition systems. No
crossover tube is required, therefore no
sooting or pilot fouling problems can
occur.
All 48HG standard units are designed for natural gas, but an accessory
LP (liquid propane) conversion kit is
available, if required.
Safety is built in — All 48HG units
have a flame rectification sensor to
quickly sense the burner flame and ignite burners almost immediately. Fast
shutdown is a certainty since the sensor reacts quickly to any flame outage
or system failure. In the event of a
shutdown, an error code is issued at
the IGC board.
Safety is also assured due to the
heating safety controls which will shut
down the unit if there is a problem. If
excessive temperatures develop, limit
switches shut off the gas valve. After 4
continuous short cycles of the
high-temperature limit switch, the IGC
board locks out the gas heat cycle to
prevent any further short cycles. This
safety feature is provided exclusively on
Carrier rooftop units. The rollout
3
Features/Benefits (cont)
switch also deenergizes the gas valve in
the event of a flame rollout.
ComfortLink™ control
The ComfortLink control is your link
to a world of simple and easy to use
rooftop units that offer outstanding
performance and value. When used
with a space temperature sensor, the
ComfortLink control’s intelligence
maintains control over the economizer
and condenser fans and optimizes the
performance of the multiple refrigeration circuits as conditions change resulting in the following features:
• higher part load efficiency
• better control of temperature and
humidity
• superior reliability
• automatic redundancy
• high ambient cooling operation at
125 F
• low ambient cooling operation at
0° F
The ComfortLink Scrolling Marquee
is very easy to use. The messages are
displayed in easy to understand
English, no decoding is required. A
No laptop computers are required
for start-up. Time schedules are built in
and the scrolling marquee display provides easy access to set points.
The ComfortLink control accepts
input from a CO2 sensor and a smoke
detector. Both are available as factoryinstalled options or as field-installed
accessories.
ComfortLink controls are fully communicating and are cable-ready for
connection to the Carrier Comfort
Network (CCN). The control communicates at 38.4 kilobaud. This provides
high-speed communications for remote
monitoring via the internet. Multiple
Centurion rooftop units can be daisychained together using a 3-wire communication bus at the rooftop level.
The ComfortLink/CCN system is a
peer-to-peer system, rather than a polling system. This results in lower cost
installations.
The Centurion rooftop units have a
terminal strip on board, therefore, the
Centurion units can operate with a
standard thermostat. Expensive interface devices are not required.
scrolling readout provides detailed explanations of control information. Only
four, large, easy-to-use buttons are required to maneuver through the entire
menu. The readout is designed to be
visible even in the brightest sunlight. A
hand-held Navigator accessory can be
used for added service flexibility.
The ComfortLink control provides
unparalleled service diagnostic information. Temperature and pressure can
be read from the display with no need
for separate gages. Other data, such as
compressor cycles, unit run time
hours, current alarms, can also be accessed. A history of alarms is also
available for viewing.
The service run test can be very helpful when troubleshooting. The user can
run test major components to determine
the root cause of a problem. The unit
can be run-tested before an installation is
complete to ensure satisfactory start-up.
To ensure reliability, the ComfortLink
control prevents reverse compressor
rotation.

cooling capacity of 261,000 Btuh and a SHC of
195,000 Btuh. For evaporator air temperatures
other than 80 F, calculate SHC correction using formula in notes under cooling capacity tables.
Unit meets design conditions for TC and SHC.
NOTE: Unit ratings are gross capacities and do not
include the effect of indoor fan motor heat. To calculate net capacities, see Step V.
III Select heating capacity of unit to provide
design condition requirement.
In Heating Capacities and Efficiencies table, note
that 48HGD024 (low heat) unit will provide
205,000 Btuh with an input of 250,000 Btuh.
IV Determine fan speed and power requirements at design conditions.
Before entering the Fan Performance tables, calculate the total static pressure required based on unit
components. Tabulated fan performance includes
filters and wet evaporator coil. Refer to Accessory/
FIOP Static Pressure — 48/50HG014-028 table
for added pressure drops.
Calculate pressure drop:
Design External Static Pressure 1.30
Economizer Static Pressure
+ 0.10
1.40 in. wg (ESP)
Enter Fan Performance tables for 48HGD024 (low
heat units, vertical supply) at 8,000 cfm and
1.40 in. wg. The rpm is 1138 and the Bhp is 6.58.
The factory-installed optional 7.5 hp motor
and alternate drive are sufficient for this operation.
V Determine net cooling capacities.
Cooling capacities are gross capacities and do not
include indoor (evaporator) fan motor (IFM) heat. To
determine input power to the motor, enter the Fan
Performance tables for 48HGD024 (low heat units)
at 8,000 cfm and 1.40 in. wg. Input watts to the
motor are 5719.
Determine net cooling capacity and net sensible
cooling capacity using the following formulas:
IFM Heat = Input Watts x 3.412 Btuh/Watt
= 5719 x 3.412
= 19,513 Btuh
Net Capacity = Gross Capacity – IFM Heat
= 261,000 – 19,513
= 241,487 Btuh
Net Sensible Cap. = Gross Sensible Cap. – IFM Heat
= 195,000 – 19,513
= 175,487 Btuh
The calculations show that a 48HGD024 unit is the
correct selection for the given conditions.
VI Select the unit that corresponds to power
source available.
The electrical data table shows that the 460-3-60
unit is available.

Capacity (TC) . . . . . . . . . . . . . . .168,000 Btuh
Gross Sensible Heat
Capacity (SHC) . . . . . . . . . . . . . .121,000 Btuh
Required Heating Capacity . . . . . . .127,000 Btuh
Condenser Entering Air Temperature . . . . . . .95 F
Indoor Air Temperature . . . . . . 80 F edb, 67 F ewb
Evaporator Air Quantity. . . . . . . . . . . . 6,000 cfm
External Static Pressure . . . . . . . . . . . .1.45 in. wg
Electrical Characteristics (V-Ph-Hz) . . . . . 230-3-60
Horizontal supply required.
II Select unit based on required cooling
capacity.
Enter Cooling Capacities table for 50HG016 at
condenser entering temperature of 95 F, evaporator
air quantity of 6,000 cfm, and indoor air temperature of 67 F. The 50HG016 unit will provide a total
cooling capacity of 200,000 Btuh and a SHC of
149,000 Btuh. For evaporator air temperatures
other than 80 F, calculate SHC correction using formula in notes under cooling capacity tables.
Unit meets design conditions for TC and SHC.
NOTE: Unit ratings are gross capacities and do not
include the effect of indoor fan motor heat. To calculate net capacities, see Step V.
III Select electric heat.
Heating load required is 127,000 Btuh.
127,000 Btuh
= 37,220 Watts Required
3.412 Btu/W
= 37.2 kW required
Enter the Electric Resistance Heater Data table, on
page 7, for the 50HG016 unit at 230-3-60. The
50 kW (46 kW at 230 v) heater most closely satisfies
the heat required.
IV Determine fan speed and power requirements at design conditions.
Before entering the Fan Performance tables, calculate the total static pressure required based on unit
components. Tabulated fan performance includes
filters and wet evaporator coil. Refer to Accessory/
FIOP Static Pressure table for added pressure drops.
18
Enter the Accessory/FIOP Electric Heat Static Pressure — 50HG014-028 Units table at the selected
unit size, cfm, and kW heater size to determine
heater pressure drop.
Calculate pressure drop:
Design External Static Pressure 1.45
50 kW Heater Static Pressure + 0.04
1.49 in. wg (ESP)
Enter Fan Performance tables for 50HG016 (horizontal supply) at 6,000 cfm and 1.49 in. wg. The
rpm is 972 and the Bhp is 3.76 (interpolation
required). The factory-installed alternate 5 hp motor
and standard drive are sufficient for this operation.
V Determine net cooling capacities.
Cooling capacities are gross capacities and do not
include indoor (evaporator) fan motor (IFM) heat. To
determine input power to the motor, enter the Fan
Performance tables for 50HG016 at 6,000 cfm and
1.49 in. wg. Input watts to the motor are 3270
(interpolation required).
Determine net cooling capacity and net sensible
cooling capacity using the following formulas:
IFM Heat = Input Watts x 3.412 Btuh/Watt
= 3270 x 3.412
= 11,157 Btuh
Net Capacity = Gross Capacity – IFM Heat
= 200,000 – 11,157
= 188,843 Btuh
Net Sensible Cap. = Gross Sensible Cap. – IFM Heat
= 149,000 – 11,157
= 137,843 Btuh
The calculations show that a 50HG016 unit with
the 50 kW heater is the correct selection for the
given conditions.
VI Select the unit that corresponds to power
source available.
The electrical data table shows that the 230-3-60
unit is available.

NOTES:
1. Direct interpolation is permissible. Do not extrapolate.
2. The following formulas may be used:
sensible capacity (Btuh)
tldb = tedb –
1.10 x cfm
tlwb = Wet-bulb temperature corresponding to enthalpy of air leaving evaporator coil (hlwb)
total capacity (Btuh)
hlwb = hewb –
4.5 x cfm
Where: hewb = Enthalpy of air entering evaporator coil
3. The SHC is based on 80 F edb temperature of air entering evaporator coil.
Below 80 F edb, subtract (corr factor x cfm) from SHC.
Above 80 F edb, add (corr factor x cfm) to SHC.

*For standard motor with standard drive, the drive range is 485 to
613 rpm (208/230 and 460-v units) or 472 to 619 (575-v units). For
standard motor with alternate drive, the drive range is 618 to 789 rpm
(208/230 and 460-v units) or 609 to 778 (575-v units). For alternate
motor with standard drive, the drive range is 778 to 1021 rpm.

Interpolation is permissible. Do not extrapolate.
Fan performance is based on filters, unit casing, and wet coil losses.
Extensive motor and electrical testing on these units ensures that
the full range of the motor can be utilized with confidence. Using
your fan motors up to the wattage ratings shown will not result in nuisance tripping or premature motor failure. Unit warranty will not be
affected. See Evaporator-Fan Motor Specifications table on page 54

794 to 974 rpm. For alternate motor with standard drive, the drive
range is 949 to 1145 rpm. For alternate motor with optional drive, the
drive range is 1126 to 1328 rpm. All other rpms require a fieldsupplied drive.
NOTES:

watts for the alternate motor is 6438. Do not adjust motor rpm such
that motor maximum Bhp and/or watts is exceeded at the maximum
operating cfm.
Static pressure losses must be added to external static pressure
before entering fan performance table.
Interpolation is permissible. Do not extrapolate.
Fan performance is based on filters, unit casing, and wet coil losses.
Extensive motor and electrical testing on these units ensures that
the full range of the motor can be utilized with confidence. Using
your fan motors up to the wattage ratings shown will not result in
nuisance tripping or premature motor failure. Unit warranty will not
be affected. See Evaporator-Fan Motor Specifications table on
page 54 for additional information.
Use of a field-supplied motor may affect wire sizing. Contact your
Carrier representative for details.

*For standard motor with standard drive, the drive range is 485 to
613 rpm (208/230 and 460-v units) or 472 to 619 (575-v units). For
standard motor with alternate drive, the drive range is 618 to 789 rpm
(208/230 and 460-v units) or 609 to 778 (575-v units). For alternate
motor with standard drive, the drive range is 778 to 1021 rpm.
For alternate motor with optional drive, the drive range is 1000 to
1227 rpm. All other rpms require a field-supplied drive.

is 4290. Do not adjust motor rpm such that motor maximum Bhp
and/or watts is exceeded at the maximum operating cfm.
Static pressure losses must be added to external static pressure
before entering fan performance table.
Interpolation is permissible. Do not extrapolate.
Fan performance is based on filters, unit casing, and wet coil losses.
Extensive motor and electrical testing on these units ensures that
the full range of the motor can be utilized with confidence. Using
your fan motors up to the wattage ratings shown will not result in nuisance tripping or premature motor failure. Unit warranty will not be
affected. See Evaporator-Fan Motor Specifications table on page 54
for additional information.
Use of a field-supplied motor may affect wire sizing. Contact your
Carrier representative for details.

*For standard motor with standard drive, the drive range is 485 to
613 rpm (208/230 and 460-v units) or 472 to 619 (575-v units). For
standard motor with alternate drive, the drive range is 618 to 789 rpm
(208/230 and 460-v units) or 609 to 778 (575-v units). For alternate
motor with standard drive, the drive range is 778 to 1021 rpm.
For alternate motor with optional drive, the drive range is 1000 to
1227 rpm. All other rpms require a field-supplied drive.
NOTES:
1. Maximum continuous Bhp for the standard motor is 4.25 (for 208/230
and 460-v units) or 3.45 (for 575-v units). Maximum continuous Bhp
for the alternate motor is 5.75. The maximum continuous watts for
the standard motor is 3171 (for 208/230 and 460-v units) or 2574 (for
2.
3.
4.
5.
6.
575-v units). The maximum continuous watts for the alternate motor
is 4290. Do not adjust motor rpm such that motor maximum Bhp
and/or watts is exceeded at the maximum operating cfm.
Static pressure losses must be added to external static pressure
before entering fan performance table.
Interpolation is permissible. Do not extrapolate.
Fan performance is based on baffles, filters, unit casing, and wet coil
losses.
Extensive motor and electrical testing on these units ensures that
the full range of the motor can be utilized with confidence. Using
your fan motors up to the wattage ratings shown will not result in nuisance tripping or premature motor failure. Unit warranty will not be
affected. See Evaporator-Fan Motor Specifications table on page 54
for additional information.
Use of a field-supplied motor may affect wire sizing. Contact your
Carrier representative for details.

*For standard motor with standard drive, the drive range is 618 to
789 rpm (208/230 and 460-v units) or 609 to 778 (575-v units). For
standard motor with alternate drive, the drive range is 485 to 613 rpm
(208/230 and 460-v units) or 472 to 619 (575-v units). For alternate
motor with standard drive, the drive range is 778 to 1021 rpm.
For alternate motor with optional drive, the drive range is 1000 to
1227 rpm. All other rpms require a field-supplied drive.
NOTES:
1. Maximum continuous Bhp for the standard motor is 4.25 (for 208/230
and 460-v units) or 3.45 (for 575-v units). Maximum continuous Bhp
for the alternate motor is 5.75. The maximum continuous watts for
the standard motor is 3171 (for 208/230 and 460-v units) or 2574 (for

575-v units). The maximum continuous watts for the alternate motor
is 4290. Do not adjust motor rpm such that motor maximum Bhp
and/or watts is exceeded at the maximum operating cfm.
Static pressure losses must be added to external static pressure
before entering fan performance table.
Interpolation is permissible. Do not extrapolate.

*For standard motor with standard drive, the drive range is 799 to
965 rpm. For standard motor with alternate drive, the drive range is
939 to 1152 rpm. For alternate motor with standard drive, the drive
range is 945 to 1187 rpm. For alternate motor with optional drive, the
drive range is 1152 to 1366 rpm. All other rpms require a fieldsupplied drive.
NOTES:
1. Maximum continuous Bhp for the standard motor is 8.63. Maximum
continuous Bhp for the alternate motor is 11.50. The maximum continuous watts for the standard motor is 6438. The maximum continuous
watts for the alternate motor is 8579. Do not adjust motor rpm such
that motor maximum Bhp and/or watts is exceeded at the maximum
operating cfm.
2. Static pressure losses must be added to external static pressure
before entering fan performance table.
3. Interpolation is permissible. Do not extrapolate.
4. Fan performance is based on filters, unit casing, and wet coil losses.
5. Extensive motor and electrical testing on these units ensures that
the full range of the motor can be utilized with confidence. Using
your fan motors up to the wattage ratings shown will not result in
nuisance tripping or premature motor failure. Unit warranty will not
be affected. See Evaporator-Fan Motor Specifications table on

*For standard motor with standard drive, the drive range is 485 to
613 rpm (208/230 and 460-v units) or 472 to 619 (575-v units). For
standard motor with alternate drive, the drive range is 618 to 789 rpm
(208/230 and 460-v units) or 609 to 778 (575-v units). For alternate
motor with standard drive, the drive range is 778 to 1021 rpm.
For alternate motor with optional drive, the drive range is 1000 to
1227 rpm. All other rpms require a field-supplied drive.

is 4290. Do not adjust motor rpm such that motor maximum Bhp
and/or watts is exceeded at the maximum operating cfm.
Static pressure losses must be added to external static pressure
before entering fan performance table.
Interpolation is permissible. Do not extrapolate.
Fan performance is based on filters, unit casing, and wet coil losses.
Extensive motor and electrical testing on these units ensures that
the full range of the motor can be utilized with confidence. Using
your fan motors up to the wattage ratings shown will not result in nuisance tripping or premature motor failure. Unit warranty will not be
affected. See Evaporator-Fan Motor Specifications table on page 54
for additional information.
Use of a field-supplied motor may affect wire sizing. Contact your
Carrier representative for details.

*As the height above sea level increases, there is less oxygen per
cubic foot of air. Therefore, heat input rate should be reduced at higher
altitudes. Includes a 4% input reduction per each 100 ft.

*Derating of the gas heating equipment to compensate for the effects of
altitude is always required. Orifice change is not required if the fuel
heating value (at sea level) is below the limits listed in the table above.
Derating conditions must be 4% per thousand feet above sea level. For
example, at 4000 ft, if the heating value of the gas exceeds 1000 Btu/
ft3, the unit will require a 16% derating. For elevations above 6000 ft,
the same formula applies. For example, at 7000 ft, the unit will require
a 28% derating of the maximum heating value per the National Fuel
Gas Code.

Minimum Circuit Amps
Maximum Overcurrent Protection

Outdoor (Condenser) Fan Motor
Rated Load Amps
*Fuse or HACR circuit breaker.
†208/230 v 75-kW Electric Heat units must use dual-point wiring. The main table lists the
branch circuit values for the refrigeration part of the system. The following two tables list the
branch circuit values for the electric heat and values for a feeder circuit for both branch circuits.
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
max voltage deviation from average voltage
= 100 x
average voltage
Example: Supply voltage is 460-3-60.
AB = 452 v
BC = 464 v
AC = 455 v
Average Voltage =
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%.
IMPORTANT: If the supply voltage phase imbalance is more than 2%, contact your local
electric utility company immediately.
50HG Units Only (Notes 3-6)
3. The 75-kW 208/240-v electric heat can be factory installed but it must be wired separately in
the field.
4. The convenience outlet full load amps (FLA) are 5, 3 and 3 for 208/230, 460, 575-v units,
respectively.
5. The FLA load amps provided in the table for electric heaters are based on 208/240, 480 and
600 v.
6. MCA calculation for 50HG014-028 units with electric heaters over 50 kW is = 1.25 x (IFM +
Power Exhaust + Convenience Outlet FLA amps) + 1.00 x (Electric Heater FLA).

NOTES:
1. Factory wiring is in accordance with the National Electrical
Codes. Any field modifications or additions must be in compliance with all applicable codes.
2. Use 75° C min wire for field power supply. Use copper wires
for all units.
3. All circuit breakers Must Trip Amps are equal to or less than
156% RLA (Rated Load Amps).
4. Compressor and fan motors are thermally protected. Threephase motors protected against primary single-phase
conditions.
5. Red jumper wire must be added between R and W1 for
Space Temperature mode and temporarily during ServiceTest mode when the heaters need to operate.

Controls
Operating sequence
Heating
48HG Units
NOTE: The 48HG units have 2 stages of gas heat.
When the thermostat calls for heating, power is sent to W
on the IGC (integrated gas unit controller) board. An LED
(light-emitting diode) on the IGC board will be on during
normal operation. A check is made to ensure that the rollout switch and limit switch are closed and the induced-draft
motor is running. The induced-draft motor is then energized, and when speed is proven with the hall effect sensor
on the motor, the ignition activation period begins. The
burners will ignite within 5 seconds.
If the burners do not light, there is a 22-second delay before another 5-second attempt. If the burners still do not
light, this sequence is repeated for 15 minutes. After the
15 minutes have elapsed, if the burners still have not lit,
heating is locked out. To reset the control, break 24-v
power to the thermostat.
When ignition occurs the IGC board will continue to
monitor the condition of the rollout and limit switches, the
hall effect sensor, as well as the flame sensor. If the unit is
controlled through a room thermostat set for fan auto.,
45 seconds after ignition occurs, the indoor-fan motor will
be energized (and the outdoor-air dampers will open to
their minimum position). If for some reason the overtemperature limit opens prior to the start of the indoor fan
blower, on the next attempt, the 45-second delay will be
shortened to 5 seconds less than the time from initiation of
heat to when the limit tripped. Gas will not be interrupted
to the burners and heating will continue. Once modified,
the fan on delay will not change back to 45 seconds unless
power is reset to the control.
When additional heat is required, W2 closes and initiates
power to the second stage of the main gas valve. When the
thermostat is satisfied, W1 and W2 open and the gas valve
closes, interrupting the flow of gas to the main burners. If
the call for W1 lasted less than 1 minute, the heating cycle
will not terminate until 1 minute after W1 became active. If
the unit is controlled through a room thermostat set for fan
auto., the indoor-fan motor will continue to operate for an
additional 45 seconds then stop. If the overtemperature
limit opens after the indoor motor is stopped within
10 minutes of W1 becoming inactive, on the next cycle the
time will be extended by 15 seconds. The maximum delay
is 3 minutes. Once modified, the fan off delay will not
change back to 45 seconds unless power is reset to the
control.
A LED indicator is provided on the IGC to monitor operation. The IGC is located by removing the heat section side
panel. During normal operation, the LED is continuously
on.
For units with economizers, the outdoor-air damper
stays at the Economizer Minimum Position while the evaporator fan is operating. The outdoor-air damper is closed
when the indoor fan is not operating.

50HG Units
Thermostat Mode: The 50HG (low, medium, and high
electric heat) units have 2 stages of electric heat (nominal
15 kW heater is single stage). When the thermostat calls
for heating, power is applied to the W1 terminal at the
unit. The unit control will energize the indoor fan contactor
and the first stage of electric heat. On units with two-stage
heating, when additional heating is required, the second
stage of electric heat will be energized when power is applied at the W2 terminal on the unit.
Space Sensor Mode: The 50HG (low, medium, and high
electric heat) units have 2 stages of electric heat (nominal
15 kW heater is single stage). When the space sensor senses a temperature that is below the heating set point, the
unit control will energize the indoor fan contactor and the
first stage of electric heat. On units with two-stage heating,
when additional heating is required, the second stage of
electric heat will be energized when the space temperature
does not reach the desired set point within the appropriate
time. See the Controls and Troubleshooting guide for more
detail.
Cooling
Economizer Control — If the economizer is available for
cooling, the unit will always try to meet demand using the
economizer before turning on a compressor. The economizer is available for cooling when:
• the outdoor temperature is below the Economizer High
Temperature Lockout (ECL.H) and above the Economizer Low Temperature Lockout (ECL.L)
• the outdoor enthalpy is low.
If the economizer is not available for cooling, the economizer will move to the Economizer Minimum Position
(MIN.P).
If the economizer is available for cooling and yet it is unable to meet demand, the unit will continue to modulate
the economizer while cycling the compressors to increase
total cooling capacity.
If the indoor fan is not operating, the economizer will be
closed.
The 48/50HG units can also be equipped with optional
CO2 sensors for additional indoor air quality control. Consult the Controls and Troubleshooting Guide for more information on IAQ features.
Cooling Using Space Sensor (T55 or T56) Control — To
operate the unit in Space Sensor mode, Unit Control Type
must be set to Space Sensor (3) and a wire must be added
between R and W1 on TB4 (see controls schematic). While
in this mode, the unit tries to maintain the Space Temperature (SPT) at one of 4 different set points: the Occupied
Cool Set Point (OCSP), the Unoccupied Cool Set Point
(UCSP), the Occupied Heat Set Point (OHSP), or the Unoccupied Heat Set Point (UHSP). The building’s occupancy is affected by a number of different factors (see Controls
and Troubleshooting Guide for details). When the building
is occupied, the occupied set points are active. When the
building in unoccupied, the unoccupied set points are active. In Space Sensor mode, the control will switch automatically between cooling and heating to maintain temperature. However, to minimize unnecessary cool to heat and
heat to cool changes, there is a 10-minute delay after the
last stage turns off before the control will switch modes.
To maintain temperature while cooling, the unit will turn
on compressors as needed when the economizer is either
unavailable or not providing enough cooling. The minimum on-time for each compressor is 3 minutes and the
minimum off-time is 5 minutes.
Units with 3 compressors (48/50HG016,020,024)
have 3 stages of cooling. Units with 2 compressors (48/
50HG014,028) have 2 stages of cooling. The economizer
is not considered a stage of cooling even though it can provide cooling in certain situations. In general, the minimum
time between increasing stages (from 1 to 2 and from 2 to
3) is 7.5 minutes, however, the minimum time between
stages can be further reduced in certain situations (see
Controls and Troubleshooting Guide). The minimum time
between decreasing stages (3 to 1 and 2 to 0) is 5 minutes.
Consult the Controls and Troubleshooting Guide for
additional information on configuring the controls for
space sensor control and adjusting the minimum compressor on-time, minimum compressor off-time, and the
minimum time between decreasing stages.
Cooling Using Thermostat Control — Thermostat cooling
begins when the Y1 input is energized. If the economizer is
available for cooling, the economizer will try to maintain
the Supply Air Temperature (SAT) at either the Low Cool
Supply Air Set Point (LCS) for a Y1 call or the High Cool
Supply Air Set Point (HCS) for a Y2 call. If the economizer
operates at 100% for 5 minutes or the economizer cooling
is not available, the unit will begin to stage compressors.
While the compressors are operating, the economizer will
try to maintain its position at 100%. However, if low suction pressures are experienced, the economizer will begin
to close in order to protect the compressors from damage.
Three different compressor-staging algorithms are available with ComfortLink™ control. They are called
Adaptive, 1-stage Y1 and 2-stage Y1. In Adaptive mode,
once compressor staging begins (see above), at least one
compressor will run as long as there is a Y1 call. On a
three-circuit machine with only a Y1 call, the second circuit
will cycle depending upon the trend in the Supply Air Temperature (SAT). If there is a Y2 call, compressors will stage
up to the maximum number available.
The 1-stage Y1 and 2-stage Y1 modes are identical if
there are only two circuits. In both cases, the stages follow
the thermostat calls directly. The two modes differ when
three circuits are available as they are on the 016, 020,
and 024 units. In 1-stage Y1 mode, a Y1 call will cause the
first compressor stage to operate immediately (there
always is a 5-second delay between compressor starts)
while in 2-stage Y1 mode, a Y1 call will cause the first two
stages to operate immediately. For either mode, all stages
will operate immediately if there is a Y2 call.
If fan request G is energized, but Y1 is not energized, the
indoor fan will operate and the economizer position will be
maintained at MIN.P.

Application data
Ductwork
Minimum temperature (48HG only)
Ductwork should be attached to the curb on all units. Interior installation may proceed before unit is set in place on
roof. If ductwork will be attached to the unit, do not drill in
condensate drain pan area — leaks may result.
Air entering the heat exchanger in heating must be a minimum of 50 F (10 C) continuous and 45 F (7.2 C) intermittent. A field-supplied outdoor-air temperature control must
be used to initiate both stages of heat whenever the
entering-air temperature is less than 45 F.
Electric heat (50HG only)
On 50HG014-028 units with electric heat, a field-supplied
90-degree elbow must be installed on the supply ductwork
below the unit discharge connection.
Thru-the-curb service connections
Roof curb connections allow field power wires and control
wires to enter through the roof curb opening.
Thermostat/space temperature sensor (T55
or T56)
Either a 2-stage cooling thermostat or a space temperature
sensor is required for all units. A field-supplied jumper is required when using a space temperature sensor. The jumper
is placed between terminals R and W1 on the unit thermostat terminal block (TB4). Refer to wiring diagram for
details.
Heating-to-cooling changeover
All units are automatic changeover from heating to cooling
when automatic changeover thermostat and subbase or
space temperature sensors are used.
Airflow
Units are draw-thru on cooling and blow-thru on heating.
Maximum airflow
To minimize the possibility of condensate blow-off from
evaporator, airflow through units should not exceed
500 cfm/nominal ton.
Minimum airflow
The minimum airflow for cooling is 300 cfm/nominal ton.
Operation Air Quantity Limits table on page 7 for minimum airflow cfm for heating.
IMPORTANT: The minimum heating cfm must be maintained to ensure proper operation in the Heating mode.
The minimum heating cfm value takes precedence over
the minimum cooling cfm value.
Minimum ambient cooling operation
temperature
All circuits are designed to operate at outdoor temperatures down to 0° F (–17.8 C).
Maximum operating outdoor-air temperature
For cooling, this temperature is 125 F (52 C). Refer to the
Cooling Capacity tables on pages 19-21 for further details.
High altitude (48HG only)
A change to the gas orifice may be required at high altitudes. Refer to Altitude Compensation charts on page 52.
74
Internal unit design
Due to Carrier’s internal unit design (draw-thru over the
motor), air path, and specially designed motors, the full
horsepower (maximum continuous bhp) listed in the
Physical Data table and the notes following each Fan Performance table can be utilized with extreme confidence.
Using Carrier motors with the values listed in the Physical and Fan Performance Data tables will not result in
nuisance tripping or premature motor failure. The unit
warranty will not be affected.
Condenser coil protection (Enviro-Shield™)
Pre-coated aluminum-fin coils have a durable epoxyphenolic coating applied to the fin prior to the fin stamping
process to provide protection in mildly corrosive coastal
environments. Pre-coated coils have an inert barrier
between the aluminum fin and copper tube. This barrier
electrically disconnects the dissimilar metals to minimize
the potential for galvanic corrosion. This economical option provides substantial corrosion protection beyond the
standard uncoated coil construction.
Copper-fin coils provide increased corrosion resistance
in moderate coastal environments where industrial air pollution is not present. All copper coils eliminate bi-metallic
construction to eliminate the potential for galvanic corrosion. Use of copper fin coils in industrial environments is
not recommended due to potential attack from sulfur,
sulfur oxide, nitrogen oxides, carbon and several other
industrial air-borne contaminants. In moderate seacoast
environments, copper-fin coils have extended life
compared to standard or pre-coated aluminum-fin coils.
E-Coated aluminum-fin coils undergo a precisely controlled scientific process that bonds an impermeable epoxy
coating to the specially prepared fin coil surface. E-Coating
produces a smooth, consistent coating that is less brittle,
more resilient and more durable than previous postcoating
processes. E-Coated aluminum-fin coils offer economical
protection and improved coil life in many contaminated
environments.
E-Coated copper-fin coils provide maximum protection
in virtually all environments, this option combines the continuous, impenetrable barrier of the E-Coating process
with the natural resistance of an all-copper construction.
E-Coated copper-fin coil assemblies ensure long life, even
in environments that combine harsh coastal conditions
with industrial contamination.
Indoor air quality
Plugged filter indicator
An indoor air quality sensor, which senses CO2, is a
factory-installed option. The sensor in conjunction with the
economizer is used to maintain indoor air quality. By
selecting this option, the minimum economizer position
can be reduced because the control will adjust economizer
position to maintain indoor air quality to the desired set
point. A wall-mounted indoor air quality sensor is a fieldinstalled accessory.
A plugged filter indicator (filter status switch) is available as
a factory-installed option and a field-installed accessory. By
measuring the pressure differential across the evaporator
section, it signals when the evaporator filters should be
cleaned.
Enthalpy sensor
Enthalpy switches are available as field-installed accessories. If only one switch is used, it is used to measure return
air enthalpy. If two switches are used they should be wired
in a differential configuration to measure the difference in
the return and outdoor enthalpies. The enthalpy switches
signify when the outdoor air is suitable for free cooling.
Fan status
A fan status switch is available as a field-installed accessory.
By sensing the pressure differential generated by the
indoor fan, it signals the ComfortLink™ system when the
indoor fan blower is operating and therefore it is very
useful for detecting broken belts, etc.
