Ductless Split-Type High Static Slim Ducted Air Handler Indoor Unit R454B 1 Ton 12,000 BTU 230V 1 Phase 60 Hz

The Ductless Split-Type High Static Slim Ducted Air Handler Indoor Unit R454B 1 Ton 12,000 BTU 230V 1 Phase 60 Hz Single-Condensing (DLFSDAH12XHK) is designed for ducted ductless heat pump applications that require higher external static capability in a compact slim-duct form factor. This unit operates on 230 volt single-phase power and is intended for longer duct runs or more restrictive duct layouts than standard low-static models, making it suitable for multi-register residential zones or light-duty commercial spaces. The R454B indoor coil must be paired with a compatible R454B single-zone outdoor heat pump, and refrigerant type and capacity alignment must be confirmed during system selection. For installation, technicians should verify electrical supply, confirm outdoor unit compatibility, design ductwork that supports higher static operation, plan condensate routing based on mounting orientation, and maintain service access to the blower compartment, coil section, filtration path, and condensate connection.
