Ductless Split-Type Multi-Poise Crossover Air Handler Indoor Unit R454B 5 Ton 60,000 BTU 208/230V 1 Phase 60 Hz

The Ductless Split-Type Multi-Poise Crossover Air Handler Indoor Unit R454B 5 Ton 60,000 BTU 208/230V 1 Phase 60 Hz (45MUAAQ60XX3) is a high-capacity crossover indoor unit intended for large ducted applications served by ductless heat pump outdoor systems. This model operates on 208/230 volt single-phase power and supports upflow, downflow, and horizontal installation, allowing placement in commercial utility rooms, ceiling platforms, or large retrofit ducted configurations. The R454B coil is designed for Puron Advance systems and requires confirmation of outdoor unit pairing, refrigerant compatibility, and capacity matching during system design. For installation, technicians must account for condensate drainage based on orientation, duct system sizing appropriate for higher airflow demand, electrical supply verification, and sufficient clearance for access to the blower section, coil area, filtration path, and drain connection during commissioning and service.
