A50 FCQ*04, 05, 06, 07 Single - Packaged Heat Pump with Optional Electric Heatand Puron Refrigerant (R-410A) Product DataWeatherMaker Single Packaged Heat Pump Rooftop3 to 6 Nominal Tons2 The New Carrier WeatherMaker Packaged heat pump rooftop units (RTU) with EcoBlue Technology were designed by customers for customers and integrate new technology to provide value added benefits never seen in this type of equipment major design features include: Patent, industry s first efficientindoor fan system using Vane Axialfan with electric commutated vari-able speed motor Reliable fixed speed scroll compres-sor on 3-5 ton sizes and 2 stagescroll technology on 6 ton sizes Upgraded unit control board withintuitive indoor fan adjustment Reliable copper tube/aluminum fincondenser coil with 5/16-in. tubingto help reduce refrigerant chargeversus prior designs New outdoor fan system with rug-ged lightweight high impact com-posite fan blade50 FCQ WeatherMaker units up to 6tons are specifically designed to fit onCarrier roof curbs that were installedback to 1989, which makes replace-ment easy and eliminates the need forcurb adapters or changing units deliver SEERs up IEERs up to and heatingHSPFs up to All models arecapable of either vertical or Carrier rooftop unit (RTU) wasdesigned by customers for no-strip screw collars, handledaccess panels, and more, the unit iseasy to install, easy to maintain, andeasy to use.

2 Precisely sized SuctionLine Accumulator to help insure reli-able operation at unit operation features include: Puron refrigerant (R-410A) Single point electrical connections optional fully integrated SystemVu controls RTU Open controller for BACnet1,LonWorks2, Modbus3 and JohnsonControls N2 3 to 5 ton models use fixed refriger-ant metering devices and 6 tonmodels use a TXV scroll compressors with internalline-break overload protection easy access tool-less filter door. Fil-ter track tilts out for filter removaland replacement. All filters are thesame size in each unitInstallation easeAll WeatherMaker units are field-convertible to horizontal airflow, whichmakes it easy to adjust to unexpectedjob-site complications. Lighter unitsmake for easy replace. Simple, fastplug-in connections to the standardintegrated unit control board (UCB).Clearly labeled connections points toreduce installation time.

3 Also, a largecontrol box provides room to work androom to mount Carrier to maintainWith the new EcoBlue Vane Axial fansystem and direct drive ECM motor,there is no longer a need to adjust beltsor pulleys as in past designs. This freesup maintenance and installation access handles by Carrier providequick and easy access to all normallyserviced components. Our no-strip screw system has superior holdingpower and guides screws into positionwhile preventing the screw from strip-ping the unit s , corrosion resistant compositedrain pan sheds water; and won t to useThe newly re-designed Unit ControlBoard by Carrier puts all connectionsand troubleshooting points in one con-venient place. Most low voltage con-nections are made to the same boardand make it easy to access it. Settingup the fan is simple by an intuitiveswitch and rotary dial rooftops have high and lowpressure switches, a filter drier, and2-in.

Do notcompare these values to sound pressure values because soundpressure depends on specific environmental factors which nor-mally do not match individual applications. Sound power valuesare independent of the environment and therefore more A-weighted sound ratings filter out very high and very low frequen-cies, to better approximate the response of average human measurements for Carrier units are taken in accor-dance with - MAXIMUM AIRFLOW RATINGS (CFM) COOLING UNITS AND ACCESSORY ELECTRIC HEAT* Electric heat modules are available as field-installed accessories for 50 FCQ UNITCOOLING STAGESOUTDOOR SOUND (dB) AT 60 DecibelUNITCOOLINGELECTRIC HEAT*MINIMUM AIRFLOW CFMMINIMUM 2-SPEED AIRFLOW (LOW SPEED)MINIMUM 2-SPEED AIRFLOW (HIGH SPEED)MAXIMUM AIRFLOW CFMMINIMUM AIRFLOW CFMMAXIMUM AIRFLOW CFM50 FCQA04900N/AN/A1500 900150050 FCQA051200N/AN/A20001200200050 FCQA061500N/AN/A25001500250050 FCQM07180012001800300018003000 Capacity ratings (cont)
