Oxbox J5MXCB004AC6HC Multi-position Cased Evaporator Coil 1.5 to 3.0 Ton R-454B

Product Description

The Oxbox J5MXCB004AC6HC is a B-cabinet, multi-position cased evaporator coil rated for 1.5 to 3.0 ton systems and designed specifically for use with R-454B refrigerant. Built with an all-aluminum coil construction, it handles heat exchange and dehumidification in the indoor air handler section of a split-system cooling or heat pump setup. A factory-installed R-454B refrigerant sensor ships with the unit, reducing field modification time. Licensed HVAC technicians working on residential or light-commercial split systems are the primary installers. The coil supports upflow, downflow, and horizontal orientations, making it adaptable to a range of air handler configurations without requiring a separate coil for each application.

This coil is suited for residential split-system installations where the air handler may be positioned in a utility closet, attic, basement, or crawl space. Its multi-position capability means a single coil covers upflow, downflow, or horizontal configurations, which is useful for contractors stocking one SKU across multiple job types. The J5MXCB004AC6HC is part of the Oxbox J5MXC cased coil series, which offers 11 available models to cover a range of system sizes and cabinet configurations. It is intended for pairing with a compatible R-454B outdoor condensing unit or heat pump.

Compatibility

Designed for use with R-454B refrigerant split systems and heat pumps in the 1.5 to 3.0 ton capacity range. Compatible with Oxbox J5MXC series system configurations. Verify cabinet width and refrigerant type on the outdoor unit before installation. Consult the Oxbox system matchup guide to confirm rated system efficiency with the specific condensing unit being paired.

Installation Notes

Installation should be performed by a licensed HVAC technician holding the appropriate EPA Section 608 certification for handling regulated refrigerants. Shut off power to the air handler and the outdoor unit at the disconnect before beginning coil replacement or new installation. Confirm the cabinet orientation and drain pan position match the intended airflow direction before securing the coil in place. Follow local mechanical codes and the manufacturer installation manual for refrigerant line sizing, drain line routing, and leak-check procedures.
