4-Ton Single-Stage Cooling – Reliable Commercial Cooling

The Trane 5TTA4048A3 provides 48,000 BTUH of nominal cooling capacity to help maintain comfortable indoor temperatures during warm-weather operation. The outdoor condensing unit is designed for use with approved matched indoor systems and AHRI-rated TXV/EEV indoor systems. The 5TTA4048A3 is part of Trane's 14 Single-Stage air conditioner platform.

ClimaTuff® Scroll Compressor – Dependable Cooling Performance

The ClimaTuff® scroll compressor provides the compression required for reliable cooling operation. The compressor incorporates internal over-temperature and pressure protection, a centrifugal oil pump, and a design intended to provide low vibration and noise. The 5TTA4048A3000A operates on 208/230V, three-phase, 60 Hz power, with a minimum branch circuit ampacity of 16.2 amps and a maximum branch circuit protection rating of 25 amps.

Spine Fin™ Coil – Efficient Outdoor Heat Transfer

The outdoor Spine Fin™ coil is designed to provide low airflow resistance and efficient heat transfer. The 5TTA4048A3 uses a 27.5-inch outdoor fan with a 1/5 HP motor. Louvered panels protect the outdoor coil on all four sides, helping provide durable construction for outdoor installation.

R-454B Refrigerant – Modern Refrigeration Platform

The Trane 5TTA4048A3 uses R-454B refrigerant and is factory charged with approximately 6 pounds, 10 ounces of refrigerant for the specified factory charging configuration. Trane states that the outdoor unit factory charge includes the outdoor condensing unit, 10 feet of tested connecting line, and the smallest rated indoor evaporative coil match. Proper system charge should always be verified according to the unit nameplate and applicable Trane charging procedures, with a specified subcooling target of 10°F.

Split System Installation Design

The split system configuration separates the outdoor condensing unit from the indoor evaporator coil or air handler, providing flexibility for equipment placement and installation. The 5TTA4048A3 uses 7/8-inch O.D. gas and 5/16-inch O.D. liquid service valve connections, with 7/8-inch O.D. gas and 5/16-inch O.D. liquid rated line sizes. Trane offers 25-, 30-, 35- and 50-foot refrigerant line sets. The current installation and operation literature specifies a maximum total refrigerant line length of 150 feet, including lift, with a maximum vertical change of 50 feet. For other line lengths and applications, Trane recommends using its applicable Refrigerant Piping Application Guide or Refrigerant Piping Software Program.

Controls & Comfort

The system includes condenser fan and compressor controls along with low- and high-pressure protection. The 5TTA4 platform supports Comfort-R™ mode with approved matched indoor equipment. As specified in the current installation literature, cooling operation for the 3- to 5-ton models has an operating range of 55°F to 120°F outdoor ambient temperature. Appropriate matched indoor equipment and optional controls should be selected according to the intended operating conditions.

Commercial Applications

The Trane 5TTA4048A3 is designed for commercial and light commercial split-system cooling applications requiring a nominal 4-ton outdoor condensing unit and 208/230V three-phase electrical service. Its outdoor-rated construction, durable galvanized-steel cabinet, weather-resistant finish, and compatibility with approved matched indoor systems make it suitable for a variety of commercial installations.

Service & Maintenance

The unit incorporates service-oriented refrigeration controls and accessible components to support installation and maintenance. A factory-supplied, field-installed liquid-line drier is standard. The outdoor coil is protected on all four sides by louvered panels, while properly selected isolation is recommended when mounting the unit on a roof to help reduce sound or vibration transmission to the building structure. Optional accessories include an anti-short cycle timer, evaporator defrost control, rubber isolator kit, extreme-condition mounting kit, sound enclosure, seacoast kit, low-ambient kit, and service valve panel cover.
