With "no- strip•screw" collars, handled access panels, and more we've made your unit easy to install, easy to maintain, easy to use, and easy to love. Easy to install: . All WeatherMaker units are convertible to horizontal air flow; no special adapter curbs are necessary. Convertible airflow design makes it easy to adjust to unexpected job -site complications. Lighter units make easy replacement. Carrier 3 -6 ton `I'C 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: . . • Carrier's easy :access handles provide qui and easy access to all.normall serviced c .y omponents. 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: • • Carrier's newly designed, piaster terminal board 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. Carrier rooftops have high and low pressure switches, a filter drier, and 2" filters standard. • FEATURES AND BENEFITS - • . • Up to 28% lighter than similar industry units. Lighter rooftops make easier replacement jobs: • 3 -6 ton units fit on existing Carrier small rooftop curb. This saves time and money on replacement jobs. i • Standardized components and layout. Standardized components and controls make service and stocking parts easier. • • Scroll compressors on all units. This makes service, stocking parts, replacement, and trouble- shooting easier. . • Field convertible airflow (3 -6 tons). Being able to convert a unit vertical airflow to horizontal makes it easy to overcome job site complications. • Easy - adjust, belt -drive motor available. Carrier provides a factory solution for most points in the fan performance table. . There's no need for field- supplied drives or motors. . , • Provisions for bottom or side condensate drain. • Capable of thru -the -base or thru- the -curb gas -line routing. • • Single -point gas / electrical connection. U • • Sloped, composite drain pan. Sloped, composite drain pan sheds water; and won't rust. coo Tr Standardized controls and control box layout. Standardized components and controls make stocking parts and service easier. • • Clean, easy Louse • control box. • Color -coded wiring. • . , • Large, laminated wiring and power drawings which are affixed to unit make troubleshooting easy. • Single, central terminal board for test and wiring connections. . • • Fast- access, handled, panels for easy access to the blower and blower motor, control box, and compressors. • "No- strip" screw system guides screws into the panel and captures them tightly without stripping the screw, the panel, or the unit. • Exclusive, newly- design indoor refrigerant header for easier maintenance and replacement. • Mechanical cooling (115 °F / 46 °C - 25 °F / -4 °C) on Direct Digital Controller (DDC) (PremierLink "" or RTU -MP controller). • Mechanical cooling (115 °F / 46 °C - 25°F/ -4 °C) on Electro - Mechanical (E /M) models, with winter start kit. . • High efficiency, gas heat with induced -draft Clue exhaust (3 -6 tons). • Induce draft motor ensures no flue gas can escape.into the indoor air stream. , • Carrier's naturally draining heat 'exchanger, unlike positive pressure heat exchangers, do not treed to be periodically, manually drained. This saves labor. and maintenance expense. , . • 2" (51mm) throw away'filters on all units. • Refrigerant filter- drier. • High and low pressure switches.

External static pressure is the static pressure difference between the return duct and the supply duct plus the static pressure caused by any FlOPs or accessories. 3. Tabular data accounts for pressure loss due to clean filters, unit casing, and wet coils. Factory options and accessories may add static pressure losses, as shown in Table 14. Selection software is available, through your salesperson, to help you select the best motor /drive combination for your application. 4. The Fan Performance tables offer motor /drive recommendations. In cases when two motor /drive combinations would work, Carrier recommended the lower horsepower option. 5.
