System functions like adaptive optimalstart, nighttime free
cooling, buildingsmoke control modes, occupied heat-ing and IAQ
support are resident in thecontrols and can be easily
integratedinto the control system strategy.Environmentally
balancedPuron refrigerant (R-410A) is an HFCrefrigerant that does
not contain chlo-rine that is damaging to the ozone layer.This
refrigerant is a safe, efficient, andenvironmentally balanced
refrigerant.Quality and reliabilityExcellent full and part load
efficienciesare achieved by using multiple scrollcompressors and
indoor coils withintertwined dual refrigerant circuits.The
compressors are equipped withcrankcase heaters and protected
byelectronic sensors and logic to controlminimum on and off times
and reverserotation. The refrigerant circuits areboth electrically
and mechanically inde-pendent, to provide standby capabilityshould
one circuit require service.Novation® heat exchanger technologyThe
Novation heat exchanger designwith microchannel condenser coil is
arobust, cost effective alternative to tradi-tional coil design for
standard applica-tions. Microchannel coils are also sturdierthan
other coil types, making them eas-ier to clean without causing
damage tothe coil.Due to the compact, all-aluminumdesign,
microchannel coils reduce over-all unit operating weight. The
stream-lined microchannel coil also reducesrefrigerant charge by up
to 40%.Microchannel coils are not recom-mended by Carrier for
marine, coastal,or industrial environments, unless
aCarrier-approved coating is applied.
Variable capacity digital scroll compressorIn air conditioning
applications, theload may vary significantly, requiring ameans to
vary the system coolingcapacity for optimal system perfor-mance and
control. The 48/50P serieslarge rooftop units with digital
scrollcompression provide a highly efficientmeans of capacity
control using scrollcompressors. The digital compressortechnology
provides smooth, vibrationfree operation by axially unloading
thecompliant scrolls. By varying theamount of time that the scrolls
areunloaded, the unit is able to preciselymatch the system capacity
to the spaceload. This feature can reduce energyconsumption,
provide better dehumidi-fication, reduce compressor cycling,and
improve comfort in the space.Humidi-MiZer® adaptive
dehu-midification systemCarrier’s Humidi-MiZer adaptive
dehu-midification system is an all-inclusivefactory-installed
option that can beordered with any Weathermaster®commercial rooftop
unit.This system expands the envelope ofoperation of the rooftop to
provideunprecedented flexibility that will meetyear-round comfort
conditions. TheHumidi-MiZer adaptive dehumidificationsystem has the
industry’s only dual dehu-midification mode setting. The
Weather-master rooftop, coupled with theHumidi-MiZer adaptive
dehumidificationsystem, is capable of operating in normaldesign
cooling mode, subcooling mode,and hot gas reheat mode.Normal design
cooling mode will oper-ate under the normal sequence ofoperation.
Subcooling mode will oper-ate to satisfy part load type
conditions
by providing both cooling andenhanced dehumidification. Hot
GasReheat mode will operate when thereis a demand for
dehumidification butno demand for space cooling. Hot GasReheat mode
will provide neutral airfor maximum dehumidification opera-tion
without over-cooling the zone.The Weathermaster 48/50P Seriesnext
generation version of Carrier’sHumidi-MiZer system includes
refriger-ant modulating valves that provide vari-able flow bypass
around the condenser.This innovative feature ensures exactcontrol
of the supply-air temperatureas the unit lowers the evaporator
tem-perature to increase latent capacity.Additionally, when the
space requiresdehumidification only, the Humidi-MiZersystem can
increase hot discharge gasbypass to the Humidi-MiZer coil in
orderto heat the air to the exact neutral staterequired – no
overcooling or overheatingwith similar latent capacity as that
pro-vided in the full subcooling mode. Greenspeed intelligence
optionGreenspeed intelligence allows lowambient mechanical cooling
and maxi-mizes unit mechanical cooling efficiencyby continuously
monitoring refrigerantcircuit efficiency and ambient conditionsto
optimize condenser fan operation. Greenspeed also reduces the unit
acous-tic footprint through the condenser fanspeed modulation,
included low soundcondenser fans, and factory installedcompressor
sound blankets. Staged/modulating gas controlStaged and modulating
gas controloptions provide a supply air temperingheat function
during conditions of lowmixed air temperature while the systemis
still in Ventilation mode.

These low, mixed air conditions occurwhen the outdoor
temperature is lowand the outside-air damper is in its min-imum
position, so that the mixing ofcold outside air and return air
results inmixed-air temperatures below 50°F.Both staged and
modulating gas con-trol options will raise the air tempera-ture
leaving the unit up to thetempering mode set point. Modulatinggas
control option offers an enhancedcontrol of leaving air temperature
setpoint by continuously modulating theheat load. The modulating
gas controlreduces the burners on/off cycles intempering mode. The
staged gas control option also pro-vides additional control stages
of heat-ing operation during the normal spacedemand heating
function. The modu-lating gas control option provides con-tinuous
heating modulation to satisfythe space demand for heat. Design

applications, such asreplacement or sound-sensitive applica-tions.
The horizontal installation allowssound to be attenuated before the
ductpenetrates the roof.
Exhaust and return optionsFor applications requiring
mechanicalexhaust, all 48/50P series units withan economizer are
available with non-modulating (CV) or modulating powerexhaust. The
75-100 ton units are alsoavailable with high capacity powerexhaust
for higher airflow or staticrequirements. Multiple exhaust
fancontrol methods are available. For applications requiring high
returnduct static pressure (>0.5 in. static) afactory installed
return fan is availablefor all 48/50P units with an economizerand
vertical return. The return fan helpsovercome the return duct
static pres-sure, which allows a reduction in thesupply fan motor
capacity. The returnfan option includes a VFD for CFM off-set
control or building static pressurecontrol. Superior space pressure
control is pro-vided by specifying one of the modulat-ing power
exhaust or return fansystems. Modulating power exhaustand return
fan systems control exhaustfan airflow rates to maintain a
user-established space pressure set point.The ComfortID™
solutionThe 48/50P ComfortLink controls fullysupport the ComfortID
system. TheComfortID system is a completely inte-grated control
system that uses state-of-the-art Direct Digital Controls (DDC)
tocontinually monitor and communicatethe varying heating and
cooling condi-tions in each zone of the building.The ComfortID
system capabilities gowell beyond temperature control. Byadding
humidity, CO2, or other IAQ sen-sors, indoor air quality and
consistentcomfort conditions can be tailor-madefor each zone.
Proper ventilation basedon number of occupants can be
preciselymaintained. Using the ComfortID systemfor
demand-controlled ventilation (DCV)allows for compliance with
ASHRAE(American Society of Heating, Refriger-ating and
Air-Conditioning Engineers)standard 62 and helps keep energy
costsdown. The ComfortID system does notmerely monitor air quality
— it maintainsair quality, adjusting to promote
buildinghealth.Indoor air quality (IAQ)All units incorporate a
sloped, stainlesssteel condensate drain pan to preventstanding
water from accumulating insidethe rooftop air-conditioning unit.
Thecondensate pan has a recessed nonfer-rous condensate drain
connection.Interior cabinet surfaces (except insupply fan discharge
section) are insu-lated with a flexible fire-retardant dual-density
fiberglass blanket, coated on
the air side. The coating contains anEnvironmental Protection
Agency(EPA) registered immobilized anti-microbial agent to
effectively resist thegrowth of bacteria and fungi.Double wall
construction in the air-stream is available as an option. Dou-ble
wall construction with Agion1 anti-microbial coating can also be
provided.These units and controls have beendeveloped to provide the
design com-munity with the flexibility to meet indi-vidual job
needs for both comfort andIAQ. The design features include:•
Optional two position OA damper or
integral economizer for the introduc-tion of high quality
ventilation air.
• Optional OA station to control theeconomizer to meet the
requiredventilation airflow.
• Multiple filter options, including car-tridge filters and MERV
15 bag filters.
• Multiple cooling capacity options tohelp match the unit size

Installation and serviceabilityAccess panelsAll full-size access
panels are hinged foreasy access to serviceable components.No
fasteners need to be removed fromany units, which reduces servicing
timeand prevents roof leaks caused by dis-carded screws puncturing
the roof.Electrical connectionsSingle point electrical connections
arestandard on all units. Electrical serviceaccess can be made
through roof curbor side of unit. All 48P units provide asingle
point gas connection.Run testingTo ensure a successful start-up,
everyrooftop unit is factory run tested.Unit designUnit design is
ETL and ETL, Canada,listed according to UL (Underwriters
Lab-oratories) Standard 1995.Scrolling marqueeWhen using the
standard scrolling mar-quee, serviceability becomes even
easier,including:• local or remote alarm and alert
monitoring• self-diagnostic run testing to confirm
control and component operation• expedited troubleshooting and
unit
repair through self-diagnostic dis-play of unit troubleshooting
alertand alarm codes with expanded textdescriptions to immediately
identifyreason for unit outage
• filter maintenance alarm• monitoring of supply-air fan run
time, permitting easy service sched-ule planning
TransducersServiceability is further facilitated withsuction and
discharge pressure trans-ducers. These allow suction pressureand
discharge pressure to be monitoredremotely with alarm capability.
Thesetransducers also control condenser headpressure to maintain
the minimum dif-ferential pressure required across thethermostatic
expansion valve (TXV) forproper operation, which reduces
energyconsumption.Non-fused disconnectA factory-installed non-fused
discon-nect (NFD) option is available to simplifyunit installation
and improve unit ser-viceability. The location of the NFD in
the main control box simplifies fieldpower supply routing into
the unit. TheNFD incorporates an access panel inter-lock feature,
ensuring that all power tothe unit will be disconnected before
aservice person opens the control box.Gas heat units (48P units)The
48P units are gas heating units,using natural gas combustion, with
twoheat sizes available for every unit.The unit heating systems
employ multi-ple heat exchanger sections, with eachsection equipped
with a 2-stage redun-dant gas valve and independent igni-tion
control, with all sections operatingin parallel.Units with gas
modulating heating areequipped with an additional modulatinggas
valve installed downstream of the2-stage redundant gas valve.Heat
exchangerThe tubular steel heat exchanger designoptimizes heat
transfer for improved effi-ciency. The tubular design permits
multi-ple passes across the supply air path.Each tube has an
individual inshotburner, ensuring uniform combustion ineach tube of
the heat exchangers. Tubesare dimpled to create a turbulent gas
flowto maximize heat efficiency and toensure uniform surface
temperatures forreduced corrosion effects, improveddurability and
long-life service. Heatexchanger material is aluminized steel
orstainless steel, for improved corrosionresistance and
reliability.Integrated gas unit controllerThe IGC (integrated gas
unit controller)ignition and safety control system isused on each
heat exchanger section.The IGC, unique to Carrier rooftopunits,
simplifies system evaluation andtroubleshooting by providing
systemstatus and visual fault notification via anon-board LED
(light-emitting diode).Ignition is initiated by a direct
sparkignition system; flame status is deter-mined by flame
rectification process.Combustion fan operation is proven bya Hall
Effect speed sensor circuit forunits equipped with 2-stage or
stagedgas heat. For units equipped with mod-ulating gas heat,
combustion fan oper-ation is proven with a pressure switch.Safeties
include flame rollout and limitswitch. Auto reset with manual
lockoutis also provided for repeated limitswitch trips. The IGC
also preventsshort-cycling due to thermostat jiggle
by ensuring a full minute heating cycleoperation on each call
for heat.Gas heat systemThe induced draft fan system draws
hotcombustion gas through the heatexchanger tubes at the optimum
rate forthe most effective heat transfer and com-bustion process.
The heat exchangeroperates under a negative pressure, pre-venting
flue gas leakage into the indoorsupply air.Flue outlet hoods with
wind baffles arelocated on the side of the unit, to mini-mize the
effects of wind on heatingoperations.Standard units use 2-stage
control forunoccupied, morning warm-up andoccupied space
heating.Additional control stages for heatingoperation are
available by specifyingthe staged gas control option.Modulating
control option is availableby specifying the modulating gas
con-trol option.A single hinged panel gains access to thecomplete
heat exchanger assembly andcontrols, for improved serviceability.A
single point gas connection providesfor easy installation.An LP
(liquid propane) conversionaccessory can be field-installed on
gasunits without staged or modulating gascontrol option (sizes
030-070 for verti-cal low heat units and sizes 030-050for vertical
high heat units).Optional modulating gas heatThe modulating gas
heat option moni-tors unit supply-air temperature andcontrols the
unit heat exchanger toprovide first-stage demand heatingcontrol,
with modulation to maintainuser-configured heating supply air
tem-perature set point.The option also provides full-firedemand
heating on heating controlcommand and tempering heat control,based
on user-configured ventilationsupply air temperature set point,
toeliminate cold draft conditions with lowmixed-air
temperatures.The modulating gas control optionconsists of a

LP — Liquid Propane
NOTES:1. Ratings are approved for altitudes to 2000 ft. At
altitudes over 2000
ft, ratings are 4% less for each 1000 ft above sea level.2. At
altitudes up to 2000 ft, the following formula may be used to
calcu-
late air temperature rise:
3. At altitudes above 2000 ft, the following formula may be
used:
4. Minimum allowable temperature of mixed air entering the
heatexchanger during half-rate (first stage) operation is 35°F.
There is nominimum mixture temperature limitation during full-rate
operation.
5. Temperature rise limits: see table.6. On VAV (variable air
volume) applications set the zone terminals to
provide minimum unit heating airflow as indicated in the table
uponcommand from Heat Interlock Relay (HIR) function.
