The Ductless Split-Type Multi-Poise Crossover Air Handler Indoor Unit R454B 1.5 Ton 18,000 BTU 208/230V 1 Phase 60 Hz (45MUAAQ18XX3) is a Bryant Puron Advance crossover ducted indoor unit engineered for applications where installers need the flexibility of a multi-poise air handler combined with ductless heat pump pairing capability. This 1.5 ton unit supports upflow, downflow, and horizontal installation, making it ideal for tight mechanical rooms, attic platforms, or retrofit ducted zones requiring directional airflow flexibility. Its R454B coil is designed to match with Bryant ductless and crossover outdoor heat pump systems, providing reliable heating and cooling performance across multi-register duct layouts. For job fit, technicians should verify outdoor compatibility, confirm line-set sizing and routing, evaluate system static pressure, and maintain service access to the blower, coil, filtration area, and condensate components.
