Features/Benefits
Every compact one-piece
unit arrives fully assembled,
charged, tested, and ready to
run.
48 Series — gas heat models
All ignition components are contained
in the compact IGC (integrated gas
controller) which is easily accessible for
servicing. The IGC control board, de-
signed and manufactured exclusively
for Carrier rooftop units, provides
built-in diagnostic capability. An LED
(light-emitting diode) simplifies trouble-
shooting by providing visual fault notifi-
cation and system status confirmation.
The IGC also contains an exclusive
anti-cycle protection for gas heat oper-
ation. 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 great-
ly improves reliability of the rooftop
unit.
The IGC also contains burner con-
trol logic for accurate and dependable
gas ignition. The LED is visible without
removing the unit control box access
panel. This LED fault-notification sys-
tem reduces service person trouble-
shooting time and minimizes service
costs. The IGC also maximizes heating
efficiency by controlling evaporator-fan
on and off delays.
Tubular, dimpled gas heat exchang-
ers 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 efficient in-shot burners and
all ignition components are contained
in an easily removable, compact
assembly.
The California Air Quality Manage-
ment Districts NOx requirement of
40 nanograms/joule or less is met on
004-006 size Low NOx models.
The extra thick Alumagard™ heat
exchanger coating provides corrosion
resistance and ensures long life
(optional stainless steel heat exchang-
ers are available).
The unsightly appearance of flue
stacks is eliminated and the effects of
wind on heating operations are dimin-
ished 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. 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 condi-
tioned space is calling for heat to
maximize efficiency.
The direct-spark ignition system
saves operating expense when com-
pared to pilot ignition systems. No
crossover tube is required, therefore no
sooting or pilot fouling problems can
occur.
All standard units are designed for
natural gas, but an accessory LP (liquid
propane) conversion kit is available.
All units have a flame rectification
sensor to quickly sense the burner
flame and ignite burners almost imme-
diately. 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
switch also deenergizes the gas valve in
the event of a flame rollout.
Quiet, efficient operation and
dependable performance
Compressors have vibration isolators
for quiet operation. Efficient fan and
motor design permits operation at low
sound levels.
Unit sizes 008-028 offer lower utility
costs through part-load operation us-
ing 2 or 3 stages of cooling.
Quiet and efficient operation is pro-
vided by belt-driven evaporator fans
(standard on all units over 5 tons). The
belt-driven evaporator-fan is equipped
with variable-pitch pulleys which allow
adjustment within the rpm ranges of
the factory-supplied pulleys.
Increased operating efficiency is
achieved through computer-designed
coils featuring staggered internally
enhanced copper tubes. Fins are
ripple-edged for strength, lanced, and
double waved for higher heat transfer.
Durable, dependable
construction
Designed for durability in any climate,
the weather-resistant cabinets are con-
structed of galvanized steel and bond-
erized, and all exterior panels are coat-
ed with a prepainted baked enamel fin-
ish. The paint finish is non-chalking,
and is capable of withstanding ASTM
(American Society for Testing and Ma-
terials) B117 500-hour Salt Spray
Test. All internal cabinet panels are
primed, permitting longer life and a
more attractive appearance for the
entire unit.
In addition, all size 004-014 units
are designed with a single, continuous
top piece to eliminate any possible
leaks at seams or gasketing. Totally en-
closed condenser-fan motors and per-
manently lubricated bearings provide
additional unit dependability.
Easy installation and
conversion
All units are shipped in the verti-
cal duct configuration for fit-up to
standard roof curbs. The contractor
can order and install the roof curb early
in the construction stage, before deci-
sions on size requirements are made.
All units feature a base rail design
with forklift slots and rigging holes for
easier maneuvering. Durable packag-
ing protects all units during shipment
and storage.
The units can be easily converted
from a vertical to a horizontal duct con-
figuration by relocating the panels sup-
plied with the unit (size 004-014 only).
To convert 004-014 units from
vertical to horizontal discharge, simply
relocate 2 panels. The same basic unit
can be used for a variety of applica-
tions and can be quickly modified at
the jobsite.
To convert 015-028 units from
vertical to horizontal discharge, use the
optional horizontal supply/return
adapter roof curb (48HJ015,017 and
48TM016-028) or accessory conver-
sion kit (48HJ020-028).
Convenient duct openings in the
unit basepans permit side-by-side or
concentric duct connections (see
Application data section) without re-
quiring internal unit modification.
NOTE: On units using horizontal sup-
ply and return, the accessory baromet-
ric relief or power exhaust MUST be
installed on the return ductwork.
Thru-the-bottom service connec-
tion capability comes standard with
the rooftop unit to allow power and
control wiring and gas connections to
be routed through the unit’s basepan,
thereby minimizing roof penetrations
(to prevent water leaks). (Thru-the-
bottom gas connection requires thru-
the-bottom accessory kit.) Power, gas
and control connections are made on
the same side of the unit to simplify
installation.
The non-corrosive sloped conden-
sate drain pan (size 004-014)
permits either an external horizontal
side condensate drain (outside the roof
curb) or an internal vertical bottom
drain (inside the roof curb). Both
options require an external, field-
supplied P-trap.
Standard 2-in. throwaway filters
are easily accessed through a remov-
able panel located above the air intake
hood. No tools are required to change
unit filters.
Belt-driven evaporator-fan motors
(optional on TM units under 6 tons)
allow maximum on-site flexibility with-
out changing motors or drives.
Low voltage wiring connections
are easily made thanks to the large ter-
minal board which is located for quick,
convenient access.
In addition, color-coded wires permit
easy tracing and diagnostics.
Proven compressor reliability
Design techniques feature computer-
programmed balance between com-
pressor, condenser, and evaporator.
Carrier-specified hermetic compres-
sors are equipped with compressor
overcurrent and overtemperature pro-
tection to ensure dependability.

All units have Carrier’s exclusive
Acutrol™ (004-014) or TXV (thermo-
static expansion valve) metering device
(015-028) which precisely controls re-
frigerant flow, preventing
slugging and flood-back, while main-
taining optimum unit performance. Re-
frigerant filter driers are standard.
Integrated economizers and
outdoor-air dampers
Available as options or accessories,
economizers and manual outdoor-air
dampers introduce outdoor air which
mixes with the conditioned air, improv-
ing indoor-air quality and often reduc-
ing energy consumption.
During a first stage call for cooling, if
the outdoor-air temperature is below
the economizer control changeover
set point, the mixed-air sensor modu-
lates the economizer outdoor-air damp-
er open to take advantage of free cool-
ing provided by the outside air. When
second-stage cooling is called for, the
compressor is 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 damper stays at minimum
position.
Accessory upgrade kits allow for
control by differential dry-bulb temper-
ature (outdoor vs return), outdoor air
enthalpy changeover, or more precise
differential enthalpy control.
Units can be equipped with different
economizer options to meet specific
controls applications. The factory-
installed or field-installed EconoMi$er IV
and EconoMi$er2 are available. The
EconoMi$er IV is used with the stan-
dard rooftop unit controls and includes
an industry standard, stand-alone,
solid-state controller. The control can be
used with a CO2 sensor for DCV (de-
mand control ventilation) operation. For
direct digital control (DDC) applications,
the EconoMi$er2 can be operated using
PremierLink controls or a third party
controller. The EconoMi$er2 includes
4 to 20 mA actuator capability for de-
mand control ventilation applications.
All economizers incorporate a paral-
lel blade, gear-driven damper system
for efficient air mixing and reliable con-
trol. In addition, the standard damper
actuator includes a spring return to
provide reliable closure on power loss.
The economizers for sizes 004-014 are
equipped with up to 100% barometric
relief capability for high outdoor air-
flow operations. Economizers for unit
sizes 004-014 are available, factory-
installed, for vertical return only. Econ-
omizers for unit sizes 015-028 are
compatible for vertical or horizontal re-
turn. An optional field-installed baro-
metric relief package is available for
size 015-028 units.
In addition, single-stage power
exhaust is available as a field-installed
accessory for EconoMi$er IV to help
maintain proper building pressure.
For units without economizer, year-
round ventilation is enhanced by an op-
tional manual outdoor-air damper. On
004-014 units, a 25% or 50% manual
damper is available as a field-installed
accessory. Unit sizes 015-028 are
equipped with a manual 25% damper.
Service options (48HJ004-
017 and 48TM004-028 units
only)
Servicing a rooftop unit has never been
easier with the factory-installed service
options for these rooftop units. These
options include the following:
• Hinged access panels are provided
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 elimi-
nating the concern of a dropped or
wind-blown panel puncturing deli-
cate roof materials. The 4 extended
access panels are also equipped with
‘‘tie back’’ retaining devices to hold
the door in the open position while
servicing the unit.
• An external, covered, 115-v Ground
Fault Interrupt (GFI) receptacle is
provided as a convenient power
source for drills, lights, refrigerant
recovery units, or other electrical
service tools. A factory-supplied step
down transformer is connected to
the “load” side of the unit main
power connection (size 004-014).
For sizes 015-028, connect the out-
let to a field-supplied and properly
fused branch circuit power supply.
• Slide out “motor-drive-blower”
reduces service time (only on
48HJ017).
• An integral non-fused disconnect
switch within the rooftop unit
reduces installation time, labor and
material costs. Safety is assured by
an interlock which prevents access
to the control box unless the switch
is in the OFF position. In addition,
the externally mounted handle
incorporates power lockout capabil-
ity to further protect service
personnel.
Carrier PremierLink™ controls
add reliability, efficiency, and
simplification (48HJ004-017
and 48TM004-028 units only)
The PremierLink direct digital controls
can be ordered as a factory-installed
option or as a field-installed accessory.
Designed and manufactured exclusively
by Carrier, the controls can be used to
actively monitor and control all modes
of operations, as well as monitor the
following diagnostics and features: unit
number, zone temperature, zone set
point, zone humidity set point, dis-
charge air temperatures, fan status,
stages of heating, stages of cooling,
damper position, outdoor-air tempera-
ture, outdoor humidity level, filter
status, fire shutdown status, IAQ (in-
door air quality) set point, enthalpy sta-
tus, differential enthalpy status, heat/
cool lockout, cfm set point, pre-
occupancy purge, economizer controls
and early morning warm-up.
This controller has a 38.4K baud
communications capability and is com-
patible with ComfortLink™ controls,
CCN (Carrier Comfort Network®) and
ComfortVIEW™ software. The Scroll-
ing Marquee and Navigator™ display
are optional tools that can be used for
programming and monitoring the unit
for optimal performance. The addition
of the Carrier CO2 sensor in the condi-
tioned space provides ASHRAE
(American Society of Heating, Refrig-
eration, and Air Conditioning Engi-
neers) 62-99 compliance and Demand
Control Ventilation.
The PremierLink peer-to-peer, Inter-
net ready communicating control is de-
signed specifically for Constant Volume
(CV) and Variable Volume and Temper-
ature (VVT®) applications. This com-
prehensive controls system allows all
Carrier 3 to 25 ton rooftops with a
3-wire communications bus to be daisy
chained together on a roof to create a
fully functional HVAC (heating,

ventilation, and air conditioning) auto-
mation system.
Indoor-air quality (IAQ) begins
with Carrier rooftops
Sloped condensate pans minimize
biological growth in rooftop units in
accordance with ASHRAE Standard
62. Two-inch filters with optional dirty
filter indicator switch provide for
greater particle reduction in the return
air. The face-split evaporator coils
improve the dehumidification capabili-
ty of standard units, maximize building
humidity control.
Optional proportional reacting CO2
sensor is available with the Econo-
Mi$er IV outdoor air damper option/
accessory to aid the IAQ benefits.
Humidi-MiZer™ adaptive
dehumidification system
(48HJ004-014)
Carrier’s Humidi-MiZer adaptive dehu-
midification system is an all-inclusive
factory-installed option that can be
ordered with any Weathermaster®
48HJ004-014 rooftop unit to meet
the demand for providing a flexible and
high performing solution to accommo-
date all of these design related issues.
This system expands the envelope of
operation of Carrier’s Weathermaster
48HJ004-014 rooftop products to
provide unprecedented flexibility to
meet year-round comfort conditions.
The Humidi-MiZer adaptive dehumidi-
fication system has the industry’s only
dual dehumidification mode setting.
The Humidi-MiZer system includes two
new modes of operation. The Weath-
ermaster 48HJ004-014 rooftop cou-
pled with the Humidi-MiZer system is
capable of operating in normal design
cooling mode, subcooling mode, and
hot gas reheat mode. Normal Design
Cooling mode is when the unit will
operate under its normal sequence of
operation by cycling compressors to
maintain comfort conditions. Subcool-
ing mode will operate to satisfy part
load type conditions when the space
requires combined sensible and a
higher proportion of latent load con-
trol. Hot Gas Reheat mode will oper-
ate when outdoor temperatures
diminish and the need for latent capac-
ity is required for sole humidity control.
Hot Gas Reheat mode will provide
neutral air for maximum dehumidifica-
tion operation.
Exclusive MoistureMi$er™
dehumidification package
(48HJ015,017 and 48TM016-
028 only)
The MoistureMi$er dehumidification
package is a result of recent advances
by Carrier in controlling comfort levels.
This factory-installed option significant-
ly improves the dehumidification capa-
bility of the rooftop unit and helps con-
trol humidity levels in the building.
This option provides increased dehu-
midification by cooling the hot liquid re-
frigerant leaving the condenser coil. The
MoistureMi$er package consists of a
subcooling coil located on the leaving-air
side of the evaporator coil. The location
of this coil in the indoor airstream en-
hances the latent capacity of the
48HJ015 and 017 and 48TM016-028
units by as much as 40%. Many build-
ings suffer from humidity damage or
poor indoor air quality due to humid
conditions. The improved latent capacity
provided by the MoistureMi$er option
reduces the building’s humidity, eliminat-
ing potential property damage and mak-
ing the space more comfortable.
The MoistureMi$er option is the
ideal IAQ option for hot and humid
regions. The operation of the
MoistureMi$er package can be con-
trolled by a field-installed, wall mount-
ed humidistat or Thermidistat™ device.
The circuit activates only when needed
(using the accessory humidistat) as op-
posed to some dehumidification sys-
tems that operate continuously. The
humidistat can be set for any humidity
level between 20% and 80% relative
humidity.The Thermidistat device can
be set for any humidity level between
50% and 90% relative humidity.
COBRA™ energy recovery
units (sizes 004-014 only)
Carrier’s factory-installed optional
COBRA units recover energy from the
building exhaust air and pre-condition
ventilation air for the rooftop unit dur-
ing winter and summer operation.
These units are designed to satisfy the
higher ventilation requirements and
other building codes while minimizing
energy costs.
Factory installation of the 62AQ
section provides the benefit of reduced
field-installation time, single point
power connections, and the assurance
of a factory test for the complete
COBRA unit. The COBRA energy
recovery section requires less mainte-
nance than other energy recovery
systems and can be serviced by any
qualified refrigeration technician.
The COBRA energy recovery units
utilize Carrier’s high-efficiency
48HJ004-014 rooftop units and pro-
vide 3 to 121/2 tons of cooling capaci-
ty with the capability to pre-condition
600 to 3000 cfm of outdoor air.
Indoor-air quality (IAQ) generally re-
fers to the level of pollutants inside a
building. These pollutants include ciga-
rette smoke, carbon dioxide exhaled by
occupants, radon gas, car exhaust,
paint fumes, and odors.
Concern over increased indoor air
pollutants has been spurred by several
issues: 1) changes in new building
construction methods and retrofit of
older buildings have reduced air
infiltration rates; 2) Synthetic materials
release airborne particles, odors,
and chemicals; and 3) HVAC systems
that bring in minimal fresh air.
In 1989, IAQ concerns caused
ASHRAE to recommend increased
ventilation for all public buildings.
Simply introducing fresh air into a
building, however, is not always
practical or cost effective. Additional
ventilation can overload HVAC
systems and increase energy costs.
Carrier’s COBRA energy recovery
unit solves this dilemma by providing
increased fresh air while keeping
increased costs to a minimum. In
addition, the COBRA energy recovery
unit helps reduce humidity levels,
which helps to prevent deterioration of
building materials and retards the
growth of mold and mildew.
The COBRA energy recovery unit
provides the best solution to retaining
the energy-conserving benefits of to-
day’s tighter building construction
while improving indoor-air quality.
