Daikin FFA12AVJU9 Ceiling Cassette Mini Split 1 Ton R-32

Product Description

The DAIKIN FFA12AVJU9 is a 1-ton ceiling cassette indoor unit designed for ductless mini split systems using R-32 refrigerant. Part of the DAIKIN FFA Series, this unit mounts flush into a standard 2x2 ceiling grid, making it well suited for commercial and residential spaces where floor or wall-mounted equipment is not practical. The R-32 refrigerant charge offers a lower global warming potential compared to R-410A systems. Licensed HVAC technicians install and commission this unit as part of a complete mini split system.

This indoor unit is designed for ceiling cassette applications in spaces such as retail environments, server rooms, offices, hotel rooms, and residential open-plan areas. The 2x2 footprint fits standard drop ceiling grids, allowing a clean, low-profile installation. According to manufacturer data, it can be matched to a compatible VISTA outdoor unit or a multi-head outdoor unit, supporting both single-zone and multi-zone configurations.

Installation Notes

Installation must be performed by a licensed HVAC technician certified to handle R-32 refrigerant under applicable EPA Section 608 regulations. Shut down and lock out all power to the system before beginning any wiring or refrigerant line work. The ceiling structure must be verified to support the weight of the cassette unit before mounting. Refrigerant line sizing, flaring, and leak testing should follow the manufacturer's installation manual and local mechanical codes.
