Daikin 24,000 BTU Oterra Series Ductless Mini Split Air Handler | R32 | Heat Pump

The Daikin FTXF24AXVJU is a 24,000 BTU-class wall-mounted indoor air handler for a compatible Oterra Series single-zone ductless heat pump system. With a nominal capacity of 2 tons, it is intended to provide direct heating and cooling for larger individual zones without conventional ductwork. Potential applications include living areas, open-plan rooms, offices, workshops, finished basements, additions, apartments, and light commercial spaces.

This listing is for the indoor air handler only. The unit does not contain a compressor and cannot heat or cool a space independently. A complete system requires the approved Daikin outdoor heat pump, refrigerant piping, communication wiring, condensate drainage, electrical components, and other installation materials.

The matched outdoor heat pump also supports automatic defrost operation during applicable heating conditions.

This model has a published low indoor sound pressure level of approximately 39 dB(A), depending on operating mode and fan speed. The indoor cabinet measures approximately 39-9/16 inches wide, 11-11/16 inches high, and 10-3/4 inches deep. Published unit weight is approximately 30.5 pounds.

Compatibility and Installation Notes

The FTXF24AXVJU is designed to pair with the Daikin RXF24AXVJU Oterra Series outdoor heat pump. The complete matched system has published ratings of up to 21 SEER2, 12 EER2, and 9.1 HSPF2. These ratings apply to the approved indoor-and-outdoor combination rather than the air handler alone.

The matched system uses 208/230V, single-phase, 60 Hz electrical service. Refrigerant connections are listed as 1/4 inch for the liquid line and 5/8 inch for the gas line. The indoor unit also requires an appropriately sized and routed condensate drain.

Installation should be completed by a qualified HVAC professional according to Daikin instructions and applicable codes. The installer must verify the outdoor-unit match, required electrical circuit, refrigerant line sizing and length, communication wiring, drainage, mounting clearances, and requirements for handling R32 A2L refrigerant.

A professional load calculation should be used to confirm capacity. Square footage estimates alone do not account for climate, insulation, ceiling height, windows, occupancy, and heat-producing equipment.
