Oxbox J5MXCA003AC6HC Multi-position Cased Evaporator Coil 1.5 to 3 Tons R-454B

Product Description

The Oxbox J5MXCA003AC6HC is a multi-position cased A-cabinet evaporator coil designed for residential split-system air conditioning applications using R-454B refrigerant. Rated from 1.5 to 3 tons nominal capacity, this coil features an all-aluminum construction and ships with a factory-installed R-454B refrigerant sensor. A piston metering device is included, and the 3/8-inch liquid line connection accommodates standard split-system piping. Licensed HVAC technicians install this coil as part of a matched indoor-outdoor system, typically paired with a compatible R-454B condenser to meet current efficiency and refrigerant compliance requirements.

This coil is suited for residential split-system cooling installations where multi-position flexibility is required. The A-cabinet cased design allows installation in upflow, downflow, or horizontal configurations, making it adaptable to a wide range of air handler and furnace setups. Its 1.5 to 3 ton range covers common residential load sizes, and the factory-installed refrigerant sensor streamlines commissioning with compatible equipment. Contractors working on new installs or refrigerant-transition replacements will find this coil appropriate for jobs requiring an R-454B-rated indoor coil.

Compatibility

Designed as an OEM-style indoor evaporator coil for residential R-454B split-system air conditioning applications. Verified system pairing includes the Oxbox J5AC3024A1000 condenser in a 2-ton 24000 BTU 13.4 SEER2 configuration. Consult Oxbox system-matching documentation to confirm compatible outdoor unit models for other tonnage combinations.

Installation Notes

Installation must be performed by a licensed HVAC technician certified to handle A2L refrigerants, including R-454B, in accordance with applicable local codes and EPA Section 608 requirements. Shut down and lock out the outdoor unit and disconnect power to the air handler before removing or installing the coil. Verify refrigerant line sizing, system static pressure compatibility, and metering device match against the outdoor unit specifications before startup. Do not use this coil with refrigerants other than R-454B without manufacturer authorization.
