Daikin FTXC18BVJU9 Mini-split Indoor Unit 18000 Btu R-32

Product Description

The DAIKIN FTXC18BVJU9 is an 18,000 BTU wall-mounted indoor unit from the Entra R-32 series, designed for use in ductless mini-split heat pump systems. Rated at 1.5 tons and operating on 208/230V single-phase power, this unit delivers both heating and cooling through an inverter-driven compressor system that modulates output to maintain setpoint temperature. It uses R-32 refrigerant, which carries a lower global warming potential than R-410A. At 19 pounds and compact in profile, it is intended for wall-mounted installation in residential and light commercial spaces. A wireless controller is included.

The FTXC18BVJU9 is suited for single-zone ductless mini-split installations in residential living spaces, bedrooms, offices, and light commercial rooms where ducted systems are impractical or unavailable. It pairs with a compatible Daikin outdoor condensing unit to form a complete heat pump system capable of year-round heating and cooling. The inverter-driven operation allows the system to maintain consistent zone temperatures without the energy waste of single-stage cycling.

Compatibility

Designed for use with a compatible Daikin outdoor condensing unit as part of a single-zone ductless mini-split heat pump system. Consult Daikin system pairing documentation to confirm the correct outdoor unit match before installation.

Installation Notes

Installation must be performed by an EPA Section 608 certified HVAC technician due to the R-32 refrigerant, which is classified as mildly flammable (A2L). Shut off all electrical power to the circuit before mounting the indoor unit or making refrigerant line connections. Follow NEC requirements for dedicated circuit sizing based on the system nameplate amperage. The indoor unit requires proper wall backing, leveling, and condensate drain routing during the rough-in phase before line-set connection.
