Oxbox J5AH4P36A1B00 Multi-position Air Handler 3 Ton Psc Motor R-454B Refrigerant

Product Description

The Oxbox J5AH4P36A1B00 is a 3-ton multi-position air handler designed for residential split-system heating and cooling applications. It operates on a PSC (permanent split capacitor) blower motor and is engineered for use with R-454B refrigerant, reflecting current low-GWP refrigerant standards. Rated at 208/230 volts, single phase, 60 Hz, this unit serves as the indoor component of a split system, moving conditioned air through the duct system while the matched outdoor unit handles refrigerant compression. Licensed HVAC technicians install and commission this equipment as part of a complete split-system installation.

This air handler is suited for residential installations where flexible positioning is required. The multi-position design supports vertical upflow, vertical downflow, and horizontal configurations, making it adaptable to a range of mechanical room, closet, attic, and crawlspace installations. It is compatible with R-454B refrigerant systems and is intended to be paired with a matched outdoor condenser or heat pump and a TXV evaporator coil. One documented pairing includes the J5HP5024A1000AA heat pump and the 5AYTXVH3A1836A TXV evaporator coil.

Key Features

• 3-ton nominal cooling capacity for residential split-system applications
• PSC blower motor provides reliable, cost-effective airflow performance
• Multi-position installation: vertical upflow, vertical downflow, and horizontal orientations supported
• Compatible with R-454B refrigerant, a lower-GWP alternative to R-410A
• Rated for 208/230V, 1-phase, 60 Hz electrical supply
• Suitable for mobile home applications per available installation documentation

Compatibility

Documented for use with the J5HP5024A1000AA heat pump and the 5AYTXVH3A1836A TXV evaporator coil as part of a complete split system. Designed for R-454B refrigerant systems; verify matched outdoor unit compatibility before installation.

Installation Notes

Installation must be performed by a licensed HVAC technician in accordance with local mechanical codes and the manufacturer's installation guide. Disconnect and lock out all electrical power before servicing or making any wiring connections. Refrigerant handling requires EPA Section 608 certification; do not release R-454B to atmosphere. Ensure ductwork connections, condensate drain lines, and electrical supply are inspected and confirmed per applicable code before startup.
