Oxbox J5AC5018A1000 Split System Air Conditioner Condenser 1.5 Ton 18000 Btu R-454B 14.3 SEER2

Product Description

The Oxbox J5AC5018A1000 is a 1.5-ton single-phase split system air conditioner condenser rated at 18,000 BTU/h. It operates on R-454B refrigerant and carries a 14.3 SEER2 efficiency rating, meeting current federal minimum efficiency standards for residential central cooling systems. This outdoor condensing unit is the core component of a split system installation and is paired with a compatible indoor air handler or coil to complete the refrigerant circuit. Licensed HVAC technicians install and commission this unit as part of a matched split system assembly.

The J5AC5018A1000 is designed for residential single-phase split system applications where a 1.5-ton cooling load is appropriate. It is compatible with matched Oxbox indoor air handlers and TXV coils to form a complete split AC system. Compatible indoor components noted in product listings include the J5AH4P18A1A00 air handler, the 5JMM4A0A24S21SA air handler, and the 5AYTXVH3A1836A TXV coil, as well as the J5GXCC005AC6HU coil. Consult the Oxbox submittal sheet for the full list of rated matched-system combinations before specifying equipment.

• 14.3 SEER2 efficiency rating meets current federal minimum efficiency requirements
• R-454B refrigerant — A2L lower-GWP refrigerant per current industry transition standards
• Single-phase electrical configuration for standard residential power supply
• Designed as part of a matched split system for rated efficiency and warranty compliance

Compatibility

Compatible indoor components identified in product data include the Oxbox J5AH4P18A1A00 air handler, the 5JMM4A0A24S21SA air handler, the 5AYTXVH3A1836A TXV coil, and the J5GXCC005AC6HU coil. Always verify matched-system combinations against the published Oxbox submittal documentation to confirm rated SEER2 performance for the specific combination installed.

Installation Notes

Installation must be performed by an EPA Section 608 certified HVAC technician due to the R-454B refrigerant classification as a mildly flammable A2L refrigerant — follow all applicable local codes and refrigerant-handling requirements for A2L systems. Disconnect and lock out all electrical power to the system before making any electrical or refrigerant connections. This condenser must be installed as part of a rated matched system to achieve the published SEER2 rating and to maintain warranty compliance. Refer to the Oxbox installation instructions and the applicable sections of ASHRAE 15 and local mechanical codes for clearance, mounting, and refrigerant circuit requirements.
