A50 TCQ*07, 08, 12, 14 Electric Cooling Rooftop Units with Heat Pump andOptional Electric Heat with Puron (R-410A) RefrigerantProduct DataWeatherMaker Single Packaged RooftopHeat Pump Units6 to Nominal Tons2 The 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 to installAll WeatherMaker units are field-con-vertible to horizontal air flow whichmakes it easy to adjust to unexpected jobsite complications. Lighter units makeeasy replacement. Carrier 6 to ton50 TCQ rooftops fit on existing Carriercurbs dating back to 1989. Also, ourlarge control box gives you room to workand room to mount Carrier to maintainEasy access handles by Carrier providequick and easy access to all normallyserviced components.

2 Our no-strip screw system has superior holdingpower and guides screws into positionwhile preventing the screw from strip-ping the unit s to useThe central terminal board puts all yourconnections and troubleshooting pointsin one convenient place, standard. Mostlow voltage connections are made to thesame board and make it easy to findwhat you re looking for and easy toaccess it. Carrier rooftops have highand low pressure switches, a filter drier,and 2-in. (51 mm) filters standard. EER up to IEER up to with Single speedindoor fan motor and up to 2-speed/VFD indoor fan motor. 6 - ton units fit on existing Car-rier Rooftop curbs making the utilityconnections the same. This savestime and money on replacement jobs. Standardized components and lay-out. Standardized components andcontrols make service and stockingparts easier.

3 Scroll compressors on all units. Thismakes service, stocking parts,replacement, and trouble-shootingeasier. Crankcase heater on all modelsprovides added protection in allapplications. Precision-sized suction line accumu-lator provides high reliability by pre-venting liquid from entering thecompressor during low ambient con-ditions and reverse cycle switch over. Field convertible from vertical tohorizontal airflow configuration onall models. No special kit requiredon 07-12 models. Supply duct kitrequired for 14 model only. 4-way reversing valve rapidlychanges the flow of refrigerant toquickly changeover from cooling toheating and heating to cooling. Easy-adjust, belt drive motor avail-able on all sizes. There s no need forfield-supplied drives or motors. Provisions for bottom or side con-densate drain.

4 Capable of thru-the-base or thru-the-curb electrical routing. Dependable time / temperaturedefrost logic provides a defrostcycle, if needed, every 30, 60, 90,or 120 minutes and is adjustable. Single -point electrical connection. Sloped, composite drain pan won trust and is self draining. Standardized controls and controlbox layout. Standardized compo-nents and controls make stockingparts and service easier. Clean, large, easy to use control box. Standard coils are copper round tube,aluminum plate fin with optional coilcoatings and copper fin design. Color-coded wiring. Large, laminated wiring and powerwiring drawings which are affixed tounit make troubleshooting easy. Single , central terminal board fortest and wiring connections. Fast-access, handled, panels for easyaccess to the blower and blowermotor, control box, and compressors.

Outdoor sound data is measured in accordance with AHRI stan-dard Measurements are expressed in terms of sound power. Do notcompare these values to sound pressure values because soundpressure accounts for specific environmental factors which do notmatch individual applications. Sound power values are indepen-dent 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 an average humanear.
