Daikin FTXC12BVJU9 Mini Split Indoor Unit 12000 Btu R-32

Product Description

The DAIKIN FTXC12BVJU9 is a wall-mount ductless mini split indoor air handler rated at 12,000 BTU/h (1 ton) and designed for single-zone residential heating and cooling applications. Part of the Daikin Entra series, this unit operates on R-32 refrigerant and uses inverter-driven compressor technology to modulate output and hold setpoint temperatures without cycling on and off at full capacity. It is rated at SEER2 18.0 and runs on 208/230V 1-Phase power. Licensed HVAC technicians install this unit as the indoor half of a matched ductless mini split system, pairing it with a compatible Daikin outdoor condensing unit.

The FTXC12BVJU9 is intended for single-zone residential installations where ductwork is impractical or unavailable, such as additions, converted spaces, sunrooms, or standalone rooms requiring independent temperature control. The unit mounts high on an interior wall and connects to the outdoor unit via a refrigerant line set and low-voltage control wiring routed through a small wall penetration. R-32 refrigerant offers a lower global warming potential than R-410A, making it a compliant choice in regions adopting updated environmental refrigerant standards. Indoor sound levels start as low as 19 dB, which is well within acceptable range for occupied living spaces.

Compatibility

Designed as a single-zone indoor wall-mount air handler for use with a compatible Daikin Entra series outdoor condensing unit. This unit is sold as the indoor component only and requires a matched outdoor unit to form a complete system. Confirm outdoor unit compatibility with Daikin documentation before ordering.

Installation Notes

Installation must be performed by an EPA Section 608 certified HVAC technician due to the R-32 refrigerant charge involved. Shut off all electrical power to the circuit before mounting the indoor unit or making any electrical or refrigerant connections. R-32 is mildly flammable (A2L classification) and requires tools and procedures appropriate for A2L refrigerants per current ASHRAE and local code requirements. Follow Daikin installation documentation for line set sizing, flare specifications, and evacuation procedures before introducing refrigerant.
