Your Carrier Packaged Heat Pump rooftop unit (RTU) was designed by customers for customers. With no--strip screw
collars, handled access panels, and more we’ve made your unit easy to install, easy to maintain and easy to use.
Easy to install:
All WeatherMastertunits are field--convertible to horizontal air flow; no special kit required on 04--09 models. Supply
duct kit required for 12 size only. Convertible airflow design makes it easy to adjust to unexpected job site complications.
Lighter units make easy replacement. Carrier 3 -- 10 ton 50HCQ rooftops fit on existing Carrier curbs dating back to 1989.
Also, our large control box gives you room to work and room to mount Carrier accessory controls.
Easy to maintain:
Easy access handles by Carrier provide quick and easy access to all normally serviced components. Our “no--strip” screw
system has superior holding power and guides screws into position while preventing the screw from stripping the unit’s
metal. Take accurate pressure readings by reading condenser pressure with panels on. Simply remove the black, composite
plug, route your gauge line(s) through the hole, and connect them to the refrigeration service valve(s). Now, you can take
refrigeration system pressure readings without affecting the condenser airflow.
Easy to use:
The newly designed, master terminal board by Carrier puts all your connections and troubleshooting points in one
convenient place, standard. Most low voltage connections are made to the same board and make it easy to find what you’re
looking for and easy to access it.
Reliable:
Each unit comes with precision sized and tested scroll compressor that is internally protected from over temperature and
pressures. Each refrigerant circuit is further protected with a high pressure, loss of charge and freeze protection switch. In
addition, a liquid line filter drier and suction line accumulator protects each circuit. Each unit is factory tested prior to
shipment to help ensure units operation once properly installed.

FACTORY OPTIONS AND/OR ACCESSORIES (cont.)
Economizer (dry bulb or enthalpy)
Economizers save money. They bring in fresh, outside air
for ventilation; and provide cool, outside air to cool your
building. This is the preferred method of low ambient
cooling. When coupled to CO2sensors, economizers can
provide even more savings by coupling the ventilation air
to only that amount required.
Economizers are available, installed and tested by the
factory, with either enthalpy or dry bulb temperature
inputs. There are also models for electromechanical as
well as direct digital controllers. Additional sensors are
available as accessories to optimize the economizers.
Economizers include gravity controlled, barometric relief
which equalizes building pressure and ambient air
pressures. This can be a cost effective solution to prevent
building pressurization.
CO2Sensor
Improves productivity and saves money by working with
the economizer to intake only the correct amount of
outside air for ventilation. As occupants fill your building,
the CO2sensor detects their presence through increasing
CO2levels, and opens the economizer appropriately.
When the occupants leave, the CO2levels decrease, and
the sensor appropriately closes the economizer. This
intelligent control of the ventilation air, called Demand
Control Ventilation (DCV) reduces the overall load on the
rooftop, saving money.
Smoke Detectors
Trust the experts. Smoke detectors make your application
safer and your job easier. Carrier smoke detectors
immediately shut down the rooftop unit when smoke is
detected. They are available, installed by the factory, for
supply air, return air, or both.
Louvered Hail Guards
Sleek, louvered panels protect the condenser coil from
hail damage, foreign objects, and incidental contact.
Convenience Outlet (powered or unpowered)
Lower service bills by including a convenience outlet in
your specification. Carrier will install this service feature
at our factory, powered or unpowered. Provides a
convenient, 15 amp, 115V GFCI receptacle.
Non--fused Disconnect
This OSHA--compliant, factory installed, safety switch
allows a service technician to locally secure power to the
rooftop.
Power Exhaust Pressure Relief
Superior internal building pressure control. This
field--installed accessory may eliminate the need for
costly, external pressure control fans.
PremierLink
This CCN controller regulates your rooftop’s performance
to tighter tolerances and expanded limits, as well as
facilitates zoning systems and digital accessories. It also
unites your Carrier HVAC equipment together on one,
coherent CCN network. The PremierLink can be factory
installed, or easily field--installed.
RTU Open, Multi--protocol Controller
Connect the rooftop to an existing BAS without needing
complicated translators or adapter modules using the RTU
Open controller. This new controller speaks the 4 most
common building automation system languages (Bacnet,
Modbus, N2, and Lonworks). Use this controller when
you have an existing BAS.
Time Guard II Control Circuit
This accessory protects your compressor by preventing
short--cycling in the event of some other failure, prevents
the compressor from restarting for 30 seconds after
stopping. Not required with PremierLink, RTU Open, or
authorized commercial thermostats.
Motorized 2--Position Damper
The new Carrier 2--position, motorized outdoor air damper
admits up to 100% outside air. Using reliable, gear--driven
technology, the 2--position damper opens to allow
ventilation air and closes when the rooftop stops, stopping
unwanted infiltration.
Manual OA Damper
Manual outdoor air dampers are an economical way to
bring in ventilation air. The dampers are available in 25%
and 50% versions.

FACTORY OPTIONS AND/OR ACCESSORIES (cont.)
Motormaster Head Pressure Controller
The Motormaster motor controller is a low ambient, head
pressure controller kit that is designed to maintain the
unit’s condenser head pressure during periods of low
ambient cooling operation. This device should be used as
an alternative to economizer free cooling when
economizer usage is either not appropriate or desired. The
Motormaster will either cycle the outdoor fan motors or
operate them at reduced speed to maintain the unit
operation, depending on the model.
Alternate Motors and Drives
Some applications need larger horsepower motors, some
need more airflow, and some need both. Regardless of the
case, your Carrier expert has a factory installed
combination to meet your application. A wide selection of
motors and pulleys (drives) are available, factory
installed, to handle nearly any application.
Thru--the--Base Connections
Thru--the--base connections, available as either an
accessory or as a factory option, are necessary to ensure
proper connection and seal when routing wire and piping
through the rooftop’s basepan and curb. These couplings
eliminate roof penetration and should be considered for
main power lines, as well as control power.
Electric Heaters
Carrier offers a full line of field--installed accessory
heaters. The heaters are very easy to use and install. All
are pre--engineered and certified.
Hinged Access Panels
Allows access to unit’s major components with
specifically designed hinged access panels. Panels are:
filter, control box, fan motor and compressor.

NOTES:
1. Outdoor sound data is measured in accordance with
AHRI standard 270 ---95.
2. Measurements are expressed in terms of sound power.
Do not compare these values to sound pressure values
because sound pressure accounts for specific environ-
mental factors which do not match individual applica-
tions. Sound power values are independent of the envir-
onment and therefore more accurate.
3. A---weighted sound ratings filter out very high and very
low frequencies, to better approximate the response of
an “average” human ear. A ---weighted measurements for
Carrier units are taken in accordance with 270---95.

* Section 313 of the Energy Independence and Security Act of 2007 (EISA 2007) mandates that the efficiency of general pur-
pose motors we use in our Light Commercial Rooftops rated at 5.0 HP and larger be increased on or after December 19,
2010. We will offer both high and standard efficient motors until inventory is depleted and then shift over solely to the high
efficient motors only.
