Daikin FDMA09AVJU9 Concealed Ducted Air Handler 9000 Btu

Product Description

The DAIKIN FDMA09AVJU9 is a single-zone concealed ducted air handler from the Aurora Series, rated at 9,000 BTU/h cooling and 10,900 BTU/h heating. It installs horizontally within a ceiling cavity, soffit, or utility space and distributes conditioned air through standard residential ductwork with no visible indoor head. Operating at 208-230 volts, single phase, 60 Hz, it uses R-32 refrigerant and delivers a high-speed airflow of 401 cubic feet per minute. External static pressure is adjustable from 0.12 to 0.60 inches WG, allowing the unit to handle longer or more complex duct runs than a standard wall-mount mini-split. Licensed HVAC technicians install and commission this unit as part of a matched Daikin outdoor system.

The FDMA09AVJU9 is suited for residential and light-commercial single-zone applications where a visible indoor head is not acceptable or practical. Typical installations include bedrooms, office suites, server rooms, and additions where existing ductwork or new short-run duct can be routed through the ceiling plenum or a framed soffit. The unit covers spaces up to approximately 350 square feet. It operates at a measured sound pressure of 32 dB(A) at high speed, making it appropriate for noise-sensitive environments. The fan offers three switchable speed steps - high, medium, and low - at 401, 338, and 279 CFM respectively.

Installation Notes

Installation must be performed by a licensed HVAC technician familiar with mini-split ducted systems and local mechanical codes. Power down and lock out the electrical circuit before making any wiring connections. Refrigerant handling requires EPA Section 608 certification; do not break the refrigerant circuit without proper recovery equipment. Verify duct static pressure requirements and select the appropriate external static pressure setting on the unit to match the duct system design before startup.
