Oxbox 5JMM5A0B36M31S Wall Mount Air Handler 3 Ton Ecm Motor R-454B Front Return

Product Description

The Oxbox 5JMM5A0B36M31S is a 3-ton wall-mount air handler designed for residential and light-commercial split systems. It uses an ECM (electronically commutated motor) blower for variable-speed airflow and reduced energy draw compared to standard PSC motors. The unit is rated for R-454B refrigerant, making it compatible with current low-GWP refrigerant system configurations. A front-return cabinet design suits installations where ductwork access is limited to the front of the unit. Licensed HVAC technicians install this air handler as the indoor component of a split cooling or heat pump system.

This air handler is intended for wall-mount installations in residential applications where floor space is limited or a vertical wall-hung configuration is required. The front-return design simplifies duct connections in tighter mechanical spaces. As the indoor section of a split system, it pairs with a matched outdoor condenser or heat pump. Installation typically occurs in utility rooms, closets, or garage spaces where wall-mount brackets can be secured to structural framing.

Key Features

• 3-ton nominal cooling capacity for standard residential split-system applications
• ECM blower motor delivers variable-speed airflow and lower operating amperage versus PSC alternatives
• R-454B refrigerant compatible, aligned with current low-GWP system requirements
• Front-return cabinet configuration for installations with restricted rear or side duct access
• Wall-mount design frees floor space in utility closets, garages, and mechanical rooms

Compatibility

Designed for use as the indoor air handler in a split cooling or heat pump system using R-454B refrigerant. Pair with a compatible 3-ton outdoor unit. Consult system matchup documentation to confirm rated system efficiency before installation.

Installation Notes

Installation must be performed by a licensed HVAC technician. De-energize all power at the disconnect and breaker before beginning any wiring or refrigerant connections. The unit must be wall-mounted to structural members capable of supporting its weight, and all refrigerant line connections are made via copper sweat fittings. Follow local mechanical codes and the manufacturer installation instructions for drain line, high-voltage, and low-voltage wiring requirements.
