Oxbox 5JMM4A0B30S21S Wall Mount Air Handler 2.5 Ton Psc Motor R-454B Refrigerant

Product Description

The Oxbox 5JMM4A0B30S21S is a 2.5-ton wall-mount air handler designed for split-system residential cooling and heating applications. Built around a PSC (Permanent Split Capacitor) blower motor, this unit circulates conditioned air through the home when paired with a compatible outdoor condensing unit or heat pump. It is engineered for use with R-454B refrigerant, a lower global warming potential alternative now specified in current-generation residential HVAC equipment. Licensed HVAC technicians handle the installation and commissioning of this unit.

The 5JMM4A0B30S21S is intended for wall-mount installations where floor space or attic access is limited and a vertically oriented air handler is the preferred configuration. This makes it a practical choice in conditioned closets, utility alcoves, and mechanical spaces common in residential new construction and retrofit projects. The unit is sized for 2.5-ton system capacities and is matched to Oxbox outdoor equipment within the JMM4 product family.

Installation Notes

Installation must be performed by a licensed HVAC technician holding the appropriate EPA Section 608 certification for handling refrigerants. Shut off all power to the system at the disconnect and breaker before making any electrical or refrigerant connections. Refrigerant line connections are copper sweat-type; follow local mechanical codes and manufacturer guidelines for line sizing and evacuation procedures. Electrical connections should comply with applicable NEC requirements for low-voltage and high-voltage wiring in air-handling equipment.
