Oxbox J5MXCC009AC6HC Multi-position Cased Evaporator Coil 3.0 to 5.0 Ton R-454B C-cabinet All Aluminum

Product Description

The Oxbox J5MXCC009AC6HC is a multi-position cased evaporator coil rated for 3.0 to 5.0 tons of cooling capacity, designed for residential split systems using R-454B refrigerant. The all-aluminum coil construction improves corrosion resistance and heat transfer efficiency compared to copper-fin designs. It ships in a C-cabinet configuration and accommodates upflow, downflow, and horizontal installations, making it adaptable to a wide range of air handler and furnace applications. Licensed HVAC technicians install this coil as part of a split cooling or heat pump system, pairing it with a compatible outdoor condensing unit and matching indoor air handler or furnace blower.

This coil is built for residential central air applications where R-454B low-GWP refrigerant is required, reflecting current industry transitions away from R-410A. The C-cabinet form factor fits standard residential installations where cabinet width and depth constraints apply. The multi-position design allows the contractor to orient the coil to match the existing ductwork layout without requiring a separate coil model for each application. Uncrated dimensions are 21 inches wide by 17.5 inches high by 20 inches deep, and the unit ships at approximately 44 pounds net weight.

Key Features

• All-aluminum coil construction for corrosion resistance and efficient heat transfer
• Multi-position installation: upflow, downflow, and horizontal configurations supported
• R-454B refrigerant compatible, meeting current low-GWP requirements
• C-cabinet cased design for straightforward duct integration
• Brazed and threaded refrigerant connections with 3/4-inch gas line and 3/8-inch liquid line sizing
• 3/4-inch NPT condensate drain connection

Compatibility

Designed for use with R-454B split cooling and heat pump systems in residential applications. Compatible with the Oxbox J5MXC cased coil product family. Refer to the system manufacturer's matchup documentation to confirm ARI-rated system combinations before installation.

Installation Notes

Installation must be performed by a licensed HVAC technician certified to handle refrigerants under EPA Section 608 requirements. Shut down all electrical power to the air handler or furnace and close the refrigerant service valves before disconnecting or connecting the coil. Refrigerant connections are brazed and threaded — follow industry-standard brazing practices and ensure the system is properly evacuated and leak-tested before charging with R-454B. Verify condensate drain lines are properly trapped and pitched per local mechanical codes before returning the system to service.
