Trane 3 Ton 15 SEER2 / 11.7 EER2 Commercial Split Air Conditioning System | 460V 3 Phase - R454B - Two Stage

Reliable 3-Ton Commercial Split Air Conditioner for Light Commercial Buildings with Flexible Installation

The Trane 5TTA4036A4 / 5TAM5C03AC21 split system is a nominal 3-ton commercial split air conditioner designed to provide dependable cooling for appropriately sized offices, retail spaces, and other light commercial applications. Combining the Trane 5TTA4036A4 outdoor condensing unit with the 5TAM5C03AC21 indoor air handler, this split system separates the outdoor heat-rejection equipment from the indoor air-distribution components to provide installation flexibility. The outdoor unit's Spine Fin™ condenser coil, durable cabinet construction, and compressor protection features support reliable cooling operation, while the indoor air handler distributes conditioned air through a compatible duct system.

• Nominal 3-Ton Cooling Capacity – Provides approximately 36,000 BTU/h of nominal cooling capacity for properly sized light commercial spaces.
• Single-Stage Cooling Operation – Provides straightforward cooling operation through a conventional single-stage compressor system.
• Spine Fin™ Condenser Coil – Uses an all-aluminum coil design to support heat transfer and resist corrosion.
• Separate Indoor and Outdoor Equipment – Allows the condensing unit and air handler to be positioned according to building layout and installation requirements.
• Ducted Air Distribution – Connects to compatible ductwork to distribute conditioned air throughout the served space.
• Durable Outdoor Cabinet – Galvanized steel construction, a weather-resistant finish, and a DuraTuff™ base help protect the outdoor unit.
• Integrated Compressor Protection – Compressor protection features help safeguard operation against specified high-pressure, low-pressure, and temperature conditions.
• Service-Oriented Design – Outdoor service access and refrigerant connections are designed to facilitate installation and routine maintenance.

Nominal 3-Ton Cooling Capacity – Dependable Commercial Comfort

The Trane 5TTA4036A4 / 5TAM5C03AC21 split air conditioning system combines a nominal 36,000 BTU/h outdoor cooling unit with a compatible indoor air handler. During cooling operation, the indoor coil absorbs heat from the building's air, while the outdoor condenser rejects that heat to the surrounding environment. The system's single-stage cooling design provides conventional on/off compressor operation. Actual cooling capacity and operating efficiency depend on the approved matched equipment combination, airflow, refrigerant piping, and installation conditions.

Outdoor Condensing Unit – Reliable Cooling Performance

The Trane 5TTA4036A4 outdoor unit is designed for split-system cooling applications and incorporates a compressor, condenser coil, outdoor fan, and refrigeration-system controls. The Spine Fin™ condenser coil supports heat rejection through its all-aluminum construction, while the outdoor fan moves air across the coil to facilitate heat transfer. Compressor protection features and refrigerant-system controls support dependable operation when the equipment is correctly installed and maintained. Confirm the precise electrical ratings, compressor specifications, and certified performance data against the manufacturer documentation for the complete model combination.

Condenser Coil and Refrigeration Controls – Efficient Heat Transfer

The outdoor condensing unit uses Trane's Spine Fin™ condenser coil technology, featuring an all-aluminum coil construction designed to provide heat transfer with corrosion-resistant materials. The outdoor refrigeration system also incorporates a liquid-line filter-drier and compressor protection features. These components support refrigerant-system operation and help protect critical equipment components. The exact efficiency rating, refrigerant charge, and approved operating limits should be verified using the product-specific technical documentation and matched-system performance data.

Split System Configuration – Flexible Installation Design

The split system design separates the outdoor condensing unit from the indoor air handler, allowing the installer to plan equipment placement around the building's available space, duct routing, electrical service, and maintenance clearances. The indoor air handler connects to compatible ductwork and refrigerant piping to provide conditioned-air distribution. Correct equipment matching, refrigerant line sizing, condensate drainage, electrical connections, and airflow setup are essential to achieve the intended performance. Installation must follow the applicable Trane instructions and local mechanical and electrical codes.

Thermostat Compatibility – Practical Comfort Control

The Trane 5TTA4036A4 / 5TAM5C03AC21 system uses conventional HVAC control principles for cooling operation. A compatible thermostat signals the system to operate when cooling is required, and the indoor blower circulates air through the evaporator coil and connected ductwork. Thermostat selection must account for the outdoor unit's electrical and control requirements, the indoor air handler configuration, and any optional accessories. The system's control capabilities and available blower settings should be confirmed in the documentation for the exact matched equipment.

Light Commercial Applications – Adaptable Ducted Cooling

The Trane 5TTA4036A4 / 5TAM5C03AC21 is intended for appropriately sized applications where a ducted split air conditioning system is suitable. Potential applications include small offices, retail establishments, and similar commercial spaces requiring centralized cooling. Its separate indoor and outdoor components allow equipment placement to be planned around building requirements. Final equipment selection should be based on a cooling-load calculation, ventilation requirements, duct design, electrical supply, and the manufacturer's approved system combinations.

Service & Maintenance – Durable Construction and Accessible Components

The outdoor condensing unit features a weather-resistant cabinet, protective louvered panels, a DuraTuff™ base, and a Spine Fin™ condenser coil. The refrigeration system incorporates a liquid-line filter-drier and compressor protection features. These design elements support equipment durability and routine servicing. Regular maintenance should include inspection and cleaning of the indoor and outdoor coils, inspection of filters and condensate drainage, verification of electrical connections, and assessment of refrigerant-system operation by a qualified HVAC technician. Service clearances, inspection intervals, and maintenance procedures should follow the manufacturer's installation and service documentation.

Warranty

Warranty coverage for the Trane 5TTA4036A4 / 5TAM5C03AC21 system must be confirmed against the applicable Trane commercial product warranty for the exact equipment models and installation. Parts and compressor coverage, warranty duration, registration requirements, exclusions, and eligibility conditions may vary according to product classification, purchase channel, installation location, and applicable warranty terms. Consult the official warranty documentation supplied with the equipment or obtain confirmation from an authorized Trane representative before relying on specific warranty periods.
