Ductless Split-Type Multi-Poise Crossover Air Handler Indoor Unit R454B 1.5 Ton 18,000 BTU 208/230V 1 Phase 60 Hz Light-Commercial

The Ductless Split-Type Multi-Poise Crossover Air Handler Indoor Unit R454B 1.5 Ton 18,000 BTU 208/230V 1 Phase 60 Hz Light-Commercial (DLFUAAH18XAK) is designed to allow a ductless heat pump outdoor unit to serve conventional ducted air distribution in small commercial or multi-room residential applications. This unit operates on 208/230 volt single-phase power and supports upflow, downflow, or horizontal installation, providing flexibility for mechanical rooms, attic platforms, or ceiling-mounted applications. The R454B indoor coil must be paired with a compatible R454B outdoor heat pump, and refrigerant and capacity alignment must be verified during system design. For installation, technicians should confirm electrical supply requirements, plan condensate routing based on mounting orientation, design ductwork suitable for multi-register airflow, and maintain service access to the blower assembly, coil section, filter path, and condensate connection for reliable commissioning and long-term service.
