High-Capacity Direct-Drive Outdoor Fan
The outdoor fan utilizes a 27.5-inch propeller blade with a direct-drive single-speed motor (1/5 HP) operating at approximately 850 RPM. Airflow is rated at 4841 CFM at 0.0 in. w.g., supporting efficient condenser heat rejection and consistent cooling performance under standard air, dry coil conditions. 

Spine Fin™ All-Aluminum Outdoor Coil
The outdoor coil features Trane’s Spine Fin™ design with 1 row at 24 FPI and 24.93 sq. ft. of face area. This all-aluminum construction enhances heat transfer efficiency while maintaining low airflow resistance. Louvered panels protect the coil on all four sides for long-term durability. 

R-454B Refrigerant & Charging Specifications
The 5TTR5042A1000A utilizes R-454B refrigerant with an approximate factory charge of 5 lb, 1 oz. The unit includes 7/8" O.D. gas and 5/16" O.D. liquid connections and is charged to a 10°F subcooling specification for accurate installation and commissioning.
