1 48 TCGas Heat/Electric CoolingPackaged Rooftop3to15 NominalTonsProduct DataC08613the environmentally sound refrigerant2 TABLE OF CONTENTSPAGEFEATURES AND NUMBER OPTIONS AND/OR COOLING RATING RATING PERFORMANCE & WEIGHTS PRESSURE / WIRING OF Carrier rooftop unit (RTU) was designed by customers for customers. With no--strip screw collars, handled accesspanels, and more we ve made your unit easy to install, easy to maintain and easy to to install:All WeatherMakerrunits are field--convertible to horizontal air flow which makes it easy to adjust to adjust to unexpectedjob site complications. Lighter units make easy replacement. Most Carrier 48TC rooftops fit on existing Carrier curbsdating back to 1989.

2 Also, our large control box gives you room to work and roomto mount Carrier accessory to maintain:Easy access handles by Carrier provide quick and easy access to all normally serviced components. Our no--strip screwsystem has superior holding power and guides screws into position while preventing the screw from stripping the unit smetal. Take accurate pressure readingsby reading condenser pressure with panels on. Simply remove the black, compositeplug, route your gauge line(s) through the hole, and connect them to the refrigeration service valve(s).Easy to use:The newly designed, central terminal board by Carrier puts all your connections and troubleshooting points in oneconvenient place, standard. Most low voltage connections are made to the same board and make it easy to find what you relooking for and easy to access it.

3 Carrier rooftops have high and lowpressure switches, a filter drier, and 2--in (51mm)filters environmentally sound refrigerant48TC3 FEATURES AND BENEFITSSS ingle cooling stage models are available from 3 -- 10 cooling stage models are available from -- 15 up to s up to s up to to 28% lighter than similar industry units. Lighter rooftops make easier replacement connections are the same because 3 -- ton units fit on existing Carrier rooftop curbs. This saves time andmoney on replacement components and layout. Standardized components and controls make service and stocking parts compressors on all units. This makes service, stocking parts, replacement, and troubleshooting convertible airflow (3 -- 15 ton).

4 Being able to convert a unit from vertical airflow to horizontal makes it easy toovercome job site complications. 15 ton models require a simple supply duct cover to field convert from factory verticalto , belt--drive motor available. Carrier provides a factory solution for most points in the fan performance for bottom or side condensate of thru--the--base or thru--the--curb gas line gas / electrical , composite drain pan. Sloped, composite drain pan sheds water; and won t controls & control box layout. Standardized components & controls make stocking parts & service filter access , easy to use control , laminated wiring and power wiring drawings which are affixed to unit make troubleshooting , central terminal board for test and wiring , handled, panels for easy access on normally accessed service No--strip screw system guides screws into the panel & captures them tightly without stripping the screw, the panel, orthe , newly--design indoorrefrigerant header for easier maintenance and cooling (115_Fto40_For46_Cto4_C) standard on all models.

5 Winter Start Kit allows cooling operationdownto25_F(--4_C) and Motor Master to --20_F(--29_C).SHigh efficiency, gas heat with induced--draft flue exhaust draft motor ensures no flue gas can escape into the indoor air designed naturally draining heat exchanger, unlike positive pressure heat exchangers, do not need to beperiodically, manually drained. This saves labor and maintenance (51mm) disposable filters on all filter--drier on each circuit is protected with a high and low pressure factory--installed options ranging from air management economizers, 2 position dampers, plus convenienceoutlets, disconnect switch and smoke Warranty: 10 yr. aluminized heat exchanger, 5 yr. compressor, 3 yr. Novation condenser coil, 1 yr.
