Trane 5MXCC009AC6HCA Multi-position Cased Evaporator Coil 36000 to 60000 Btu/h 21 Inch Cabinet R-454B

Product Description

The Trane 5MXCC009AC6HCA is a multi-position cased A-coil evaporator designed for residential and light-commercial split-system cooling and heat pump applications using R-454B refrigerant. Rated at 36,000 to 60,000 BTU/h (3 to 5 tons nominal), this coil fits a 21-inch wide cabinet and supports upflow, downflow, and horizontal orientations from a single unit. A factory-integrated flow control check valve is included to maintain system efficiency across operating modes. The coil ships cased and is compatible with heat pump and cooling-only outdoor units. Licensed HVAC technicians handle installation as part of new system builds or refrigerant-conversion retrofits.

This coil is used in residential split-system and heat pump installations where the air handler or furnace is located indoors in a closet, utility room, attic, or crawlspace. Its multi-positional design covers the most common duct configurations without requiring a separate horizontal kit, making it a practical fit for varied installation layouts. The 5MXCC009AC6HCA is part of the Trane 5MXC Series and has been listed in complete system configurations paired with upflow gas furnaces and matching R-454B condensing units.

Key Features

• Supports upflow, downflow, and horizontal airflow configurations from one cased enclosure
• Rated for 36,000 to 60,000 BTU/h cooling capacity across 3 to 5 ton system pairings
• Designed for R-454B refrigerant, compliant with current low-GWP refrigerant requirements
• Factory-installed flow control check valve supports both cooling-only and heat pump operation
• Factory-installed R-454B refrigerant leakage sensor included per leak mitigation requirements
• 21-inch cabinet width with brazed and threaded refrigerant connections: 3/4-inch gas line, 3/8-inch liquid line

Compatibility

The 5MXCC009AC6HCA is part of the Trane 5MXC Series and has been used in documented system configurations with Trane and RunTru by Trane R-454B condensing units and upflow gas furnaces. Confirm outdoor unit tonnage, refrigerant type, and airflow requirements against the Trane system combination guide before installation.

Installation Notes

Installation must be performed by a licensed HVAC technician certified to handle R-454B refrigerant under applicable EPA Section 608 requirements. Shut down and lock out all electrical power to the air handler or furnace and the outdoor condensing unit before beginning coil installation or refrigerant line connections. Refrigerant connections are brazed and threaded — follow Trane published installation instructions for proper line-set sizing, brazing procedures, and leak testing before system startup. Refer to local mechanical codes and the manufacturer installation manual for drain pan, condensate line, and duct connection requirements.
