FEATURES/BENEFITS
Carrier’s Centurion 48PG commercial packaged rooftop unit is
Carriers most efficient, easiest to service, and most reliable rooftop
unit utilizing Puron refrigerant.
Premium Performance
The Centurion 48PG Series provides ARI (Air Conditioning and
Refrigeration Institute) certified cooling SEERs (Seasonal Energy
Efficiency Ratios) up to 14.8, EERs (Energy Efficiency Ratio) up
to 12.5 and IPLVs (Integrated Part--Load Values) up to 13.3. Gas
heating efficiencies are as high as 82%.
The 48PG unit well exceeds ASHRAE (American Society of
Heating, Refrigeration and Air Conditioning Engineers) 90.1 and
ENERGY STARrlevels. These efficiency ratings ensure low
operating costs, qualify for attractive utility rebates in many areas
and earn credits for Leadership in Energy and Environmental
Design (LEEDt) issued by Green Building Council.
These units offer ultra--high energy efficiency and environmental
benefits by utilizing Carriers Puronr(R--410A) refrigerant that
eliminates all concerns of mandated refrigerant phase out of R--22
(HCFC) in 2010. Each unit has been specifically designed for use
with Puron refrigerant to provide years of optimum efficiency.
Easy Installation
The 48PG rooftop units accommodate easy installation.
Field--convertible units easily switch from vertical to horizontal
configuration. Units come factory standard with vertical discharge
and return duct configuration but can be easily converted in the
field for horizontal airflow. If needed, a factory option can be
ordered on larger sizes to specifically meet your exact
configuration, further saving installation costs.
The entire Centurion 48PG Series from 2 to 25 ton only uses 5
roof curb sizes. The contractor can order and install the roof curb
early in the construction stage, before decisions on size
requirements are made.
Unit controls provide optimum flexibility to meet any application
or customer requests. A choice of either base electro--mechanical
controls or the popular integrated intelligent ComfortLinkt
controls can be ordered from the factory.
Large component areas facilitate easy installation for electrical, gas
or any other field accessory that may be required.
All units feature rigid base rails with rigging holes for easier
maneuvering, rigging, and lifting to and on the job site. Durable
packaging protects all units during shipment and storage.
A full range of time saving factory--installed options are available
such as power exhaust, hail guards, breakers, smoke detectors, and
air management devices. All factory options are preengineered and
certified.
Large and accessible wiring terminal boards, located in the base
unit control box, facilitate connections to room thermostat or
sensor, outdoor thermostat(s), and economizer. Hinged service
panels are provided, permitting easy access.
Thru--the--curb power and control wiring connections route
through both the curb and unit, minimizing roof penetrations.
Connections are located in an enclosed area away from harsh
ambient conditions, eliminating water entry. Both power and
control connections are made on the same side of the unit to
simplify installation. In addition, color--coded and labeled wires
permit easy tracing and diagnostics.
The Carrier Centurion units with ComfortLink controls will
operate in the cooling mode down to 0_F ambient temperature,
eliminating the need for expensive aftermarket low ambient
controllers while providing comfort in the harshest environments.
Easy Maintenance and Service
Maintaining and servicing a rooftop unit has never been easier
thanks to the new Centurion design. Integrated hinged access
panels for the filter, indoor--fan motor/blower assembly,
compressors, control box, and gas heat areas provide quick access
to major components.
Each hinged panel has multiple heavy--duty quarter--turn
latches and is permanently mounted to the unit, thereby
eliminating the concern of a dropped or wind--blown panel
puncturing delicate roof materials. Door tie downs are also
provided to ensure panels remain stationary, eliminating any panel
blowback conditions.
Indoor fan system slides out for easy access. Blower wheels,
motors, belts, and bearings can be easily serviced and maintained.
Evaporator and condenser coils are of a single slab/single pass
design that facilitates optimum cleaning without unit disassembly
or coils separation as with hybrid type coil designs. Each coil has a
dedicated access door to ensure ease of cleaning.

Optional ComfortLink Controls
provide temperature, pressure readings and all diagnostics
electronically on the unit by utilizing a large visual display on the
Scrolling Marquee. All messages are largely displayed in full text
so no decoding is required. All sensor information can be accessed
at the Scrolling Marquee, so no gages are needed. If remote
capabilities are necessary, ComfortLink provides network
capabilities as well.
Optional Humidi--MiZertAdaptive
Dehumidification System
Carriers Humidi--MiZer adaptive dehumidification system is an
all--inclusive factory--installed option that can be ordered with any
Centurion 48PG03--28 rooftop unit.
This system expands the envelope of operation of Carrier’s
Centurion rooftop products to provide unprecedented flexibility to
meet year--round comfort conditions.
The Humidi--MiZer adaptive dehumidification system has the
industry’s only dual dehumidification mode setting. The
Humidi--MiZer system includes two new modes of operation.
The Centurion 48PG03--28 rooftop coupled with the
Humidi--MiZer system is capable of operating in normal design
cooling mode, subcooling mode, and hot gas reheat mode. Normal
design cooling mode is when the unit will operate under its normal
sequence of operation by cycling compressors to maintain comfort
conditions.
Subcooling mode will operate to satisfy part load type conditions
when the space requires combined sensible and a higher proportion
of latent load control. Hot Gas Reheat mode will operate when
outdoor temperatures diminish and the need for latent capacity is
required for sole humidity control. Hot Gas Reheat mode will
provide neutral air for maximum dehumidification operation.
Optional fan and filter indicator switches will alert necessary
personnel when filters require changing or the system fan is not
operating properly.
DedicatedhingedfilterdoorandwithanEasyGlidetslide out
filter tracks make air filter replacement easy. This eliminates the
need to reach within the unit. All filters are a standard off--the--shelf
size for easy availability and lower replacement costs.
Compressors are located in a dedicated insulated compartment that
allows troubleshooting without creating air bypass that causes
misreadings and diagnostics.
Optional EnergyXtSystem
EnergyX is a factory integrated, single piece, fully tested and
certified energy recovery system specifically designed for the PG
series rooftop product family (vertical return duct only).
The EnergyX system recycles exhausted air and provides latent
and sensible energy exchange to intake air prior to entering either
the unit DX coil or heating section. This preconditioning of air
allows even higher operating efficiencies and increased comfort
control. Operating cost savings of up to 4 tons per 1,000 cfm in
cooling and 80,000 Btu/hour per 1,000 cfm in heating can be
achieved by the EnergyX system. This also would allow for the
base unit capacity requirements reduction and installation cost
savings, while providing lower life--cycle energy consumption
during operation.
The Combined Efficiency (CEF) by ARI Guideline V can be
higher than 19.0. EnergyX Energy Recovery Whell also is rated in
accordance with ARI 1060 and has UL/CUL certification.
EnergyX system comes with the following standard features:
SDouble wall fully gasketed hinged access panels with
quarter--turn handles.
SDirect or belt drive exhaust and intake blower motors with
centrifugal fans.
SExhaust and Intake 2--in filters (exhaust filters are optional).
SSingle point electrical connection.
SRotary heat exchanger wheel with desiccant silica gel coating.
S“Stop Jog” logic that prevents dirt and contaminants from
building on the wheel by rotating the wheel while the pressure
differential is sensed (provided with Economizer bypass models
only).
SAir flow test ports to properly balance the exhaust and intake air.
SPre--assembled exhaust and intake hoods.
SFive year wheel warranty.
The following optional features are available with the
EnergyX system:
Frost protection
In extremely cold climates, this option monitors wheel pressure
drop and outside temperature. When outside air temperature is
20_F or lower and the pressure drop measurement confirms frost
build--up, the wheel activates and exhaust fan energizes to remove
accumulated frost.
Motor Status Switch
This factory option monitors the system pressure drop of all
EnergyX motors, which includes the intake, exhaust and rotating
energy wheel motors. If lack of pressure is detected, a signal is sent
to a field--supplied 24 volt indicator light advising that
maintenance is required (not available on 48PG03--07 units).
Filter Maintenance Switch
This factory--installed option monitors pressure drop through both
outside air and exhaust air filters. If excess pressure drop is
detected, a signal is sent to a field--supplied 24 volt indicator light
advising that maintenance is required (not available on 03--07
units). Exhaust filters are included.
Indoor Air Quality Begins With Carrier Rooftops
Two--in. disposable filters are factory furnished as standard in
every unit with the capability of accommodating 4--in. filters as
well as factory--installed MERV--8 pleated filters. The same track is
used so no special field kits are required on 48PG03--16 units. On
48PG20--28 units a factory--installed option is available.
Internally sloped condensate pans are self--draining to ensure
minimizing biological growth in rooftop units in accordance with
ASHRAE Standard 62.
All 48PG03--16 units use a high impact polycarbonate slide--out
condensate pan while the 48PG20--28 units use an epoxy
powder--coated steel condensate pan.
Unit uses foil--faced cleanable insulation that is securely fastened.
Selected panels are mechanically fastened for added support. All
edges are either sealed or encapsulated so no fibers enter the
airstream.
Optional tilt--out economizers (sizes 03--16) with single enthalpy
controls maximize building humidity control.
Built--in capability for DCV (demand control ventilation) is
standard and integrates with CO2sensors, both as a
factory--installed option or a field--installed accessory.
Belt--driven evaporator fans provide quiet and efficient
operation. 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 motor and drive options are available to match system
airflow and static pressure requirements.

Durable, Dependable Construction
Weather--resistant cabinets are constructed of galvanized steel
and all exterior panels are coated with a prepainted baked enamel
finish. The paint finish is a non--chalking type that provides years
of maximum aesthetic protection.
Fully--insulated cabinets include non--fibrous, foil--faced
cleanable insulation that is mechanically secured and encapsulated
in unit design.
Totally enclosed condenser--fan, gas heat vent motor, and
evaporator fan motor use permanently lubricated bearings to
provide additional unit dependability. The shaft--down design of
the condenser fan also ensures protection from the continued harsh
environments.
Quality and Reliability
To assure optimum life expectancy and performance, every rooftop
unit is factory run tested prior to shipping to the job site. Individual
components are also tested at many levels to assure than only the
best parts make it into the Carrier rooftop units. All units are
manufactured in a facility registered to ISO 9001:2000.
Reliable, fully hermetic scroll compressors with crankcase
heater(s) are mounted on a dedicated formed pad and are secured
for quiet operation.
A TXV (thermostatic expansion valve) for refrigerant metering
on each circuit allows efficient operation up to 125_Fambient
cooling temperature, with removable power head.
Each circuit contains a solid core liquid line filter drier specifically
designed for Puron refrigerant systems.
Units contain provisions to eliminate internal damage if a blower
motor belt breaks or comes off during operation. Specially located
stop bars or strategically located belt drive eliminates damages to
sensitive areas such as coils, piping and metering devices.
Standard warranty coverage provides one--year parts warranty,
5--year compressor warranty, and 10--year aluminized gas heat
exchanger warranty (15 years on stainless steel heat exchanger).
Integrated Economizers and Outdoor Air
Management
During a call for cooling, if the outdoor--air temperature is below
the control changeover set point, 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.
Gear driven, spring return, close on power loss economizers
with dry bulb or single enthalpy are available as a factory--installed
option as well as two--position motorized dampers, manual
dampers and power exhaust. All provide the flexibility to meet any
application needs or codes.
Ultra Low Sound
Outdoor sound levels of 72 dB are the lowest in the industry for
this type of equipment. Low sound levels allow for maximum
installation flexibility and greater indoor environmental comfort,
and reduce or eliminate the need for expensive sound barriers
requiredbymanyothers.
Integrated Gas Heating Unit Controller (IGC)
Provides 2--stage Heating Capacity Control on All
Sizes.
All ignition components are contained in the compact IGC that is
easily accessible for servicing. The IGC control board, designed
and manufactured exclusively for Carrier rooftop units, provides
built--in diagnostic capability. An 4 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 automatic 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 Alumagardtheat exchanger coating provides
corrosion resistance and ensures long life. An optional stainless
steel heat exchanger is also available.
The induced draft combustion system eliminates the unsightly
appearance of flue stacks and diminishes the effects of wind on
heating operations. 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.
Safety is built in
All 48PG units have a flame rectification sensor to quickly sense
the burner flame. 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.
Heating safety controls 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 switch
also de--energizes the gas valve in the event of a flame rollout.

ComfortLinktControl Option
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
controls’ intelligence maintains control over the economizer and
condenser fans and optimizes the performance of the refrigeration
circuits as conditions change resulting in the following features:
Sbetter control of temperature and humidity
Ssuperior reliability
Sautomatic redundancy
Slow ambient cooling operation to 0_F
Smore accurate diagnostics, at unit or remote
The ComfortLink Scrolling Marquee is very easy to use. The
messages are displayed in easy to understand English, no decoding
is required. A 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 handheld
Navigatortaccessory or System Pilottdevice can be used for
added service flexibility.
The ComfortLink control provides unparalleled service diagnostic
information. Temperature and pressure can be read directly 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.
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 CO2sensor 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 Networkr
(CCN) communication network. The control communicates at 38.4
kilobaud. This provides highspeed 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.
3VtControl System
The Centurion rooftop unit is linkage compatible for use with the
3V zoning system. Carriers 3V control system provides optimized
equipment control through airside linkage. Linkage allows the
Centurion rooftop unit to adjust its supply air temperature set
points and occupancy schedules to run in the most efficient
manner. The 3V zoning system maintains precise temperature
control in the space by regulating the flow of conditioned air into
the space using Carrier’s VVTRZone and Bypass Controllers.

SELECTION PROCEDURE (WITH 48PGE06 EXAMPLE)
I. Determine cooling and heating requirements at design
conditions.
Given:
SRequired Gross Cooling
Capacity(TC)................57,000Btuh
SGross Sensible Heat
Capacity(SHC)...............37,000Btuh
SRequiredHeatingCapacity........90,000Btuh
SCondenser Entering Air
Temperature................95_F Summer
SIndoor Air Temperature ......80_F edb, 67_Fewb
SEvaporator Air Quantity............1,700cfm
SExternalStaticPressure............0.60in.wg
SElectricalCharacteristics(V--Ph--Hz).....230--3--60
Vertical supply required.
II. Select unit based on required cooling capacity.
SEnter Cooling Capacities table for 48PGE06 at condens-
er entering temperature of 95_F, evaporator air quantity
of 1,700 cfm, and indoor air temperature of 80/67_F.
The 48PGE06 unit will provide a total cooling capacity
of 60,300 Btuh and a SHC of 41,800 Btuh. For evapor-
ator air temperatures other than 80_F, calculate SHC
correction using formula in notes under cooling capacity
tables.
SUnit meets design conditions for TC and SHC
SNOTE: Unit ratings are gross capacities and do not in-
clude 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
48PGE06 (medium heat) unit will provide 91,500 Btuh
with an input of 113,000 Btuh.
IV. Determine fan speed and power requirements at design
conditions.
SBefore entering the Fan Performance tables, calculate the
total static pressure required based on unit components.
Tabulated fan performance includes unit casing, filters,
and wet evaporator coil.
SCalculate pressure drop:
Design External Static Pressure 0.60
0.60 in.wg (ESP)
SEnter Fan Performance tables for 48PGE06 (medium
heat units, vertical supply) at 1,700 cfm and 0.60 in. wg.
The rpm is 826 and the Bhp is 0.6. The factory--installed
1--1/2 hp motor and standard drive are sufficient for this
operation.
V. Determine net cooling capacities.
SCooling capacities are gross capacities and do not in-
clude indoor (evaporator) fan motor (IFM) heat. To
determine input power to the motor, enter the Fan
Performance tables for 48PGE06 (medium heat units) at
1,700 cfm and 0.60 in. wg. Calculated input watts to the
motor are 613.
SDetermine Input Watts
Input Watts = (746 x Bhp)/(motor eff)
Input Watts = (746 x 0.60)/(0.73)
Input Watts = 613
SDetermine net cooling capacity and net sensible cooling
capacity using the following formulas:
IFM Heat = Input Watts x 3.412 Btuh/Watt
= 613 x 3.412
= 2091 Btuh
Net Capacity = Gross Capacity -- IFM Heat
= 60,300 -- 2091
= 58,208 Btuh
Net Sensible Cap. = Gross Sensible Cap. -- IFM Heat
= 41,800 -- 2091
= 39,709 Btuh
The calculations show that a 48PGE06 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 230--3--60 unit is
available.
