Daikin FTA42AAVJUD 42000 Btu Mini Split Air Handler R-32

Product Description

The DAIKIN FTA42AAVJUD is a multi-position mini split air handler rated at 42,000 BTU/h, designed for use with R-32 refrigerant systems operating at 208/230 volts, 1-phase power. The unit ships with a factory-installed disconnect, simplifying rough-in and inspection compliance. At 53.4 inches tall, 21 inches wide, and 21 inches deep, this air handler is built for installations where flexible positioning is required. It is intended for installation by licensed HVAC technicians familiar with mini split systems, low-voltage controls, and R-32 refrigerant handling procedures.

The FTA42AAVJUD is part of the Daikin SkyAir product line, targeting commercial and light-commercial applications where a ducted or multi-position indoor unit is preferred over a traditional wall-mounted cassette. Its multi-position design allows horizontal or vertical mounting to fit varied mechanical room and ceiling plenum configurations. This unit pairs with compatible Daikin SkyAir condensing units and is suited for retail, office, and similar conditioned spaces requiring higher-capacity zoned climate control.

• Compact footprint at 21 inches wide and 21 inches deep for space-constrained mechanical areas

Compatibility

Designed for use with compatible Daikin SkyAir R-32 condensing units. No additional specific model compatibility data was provided in the source information. Verify compatible outdoor unit pairings against Daikin engineering submittal documentation before installation.

Installation Notes

Installation must be performed by a licensed HVAC technician certified to handle R-32 refrigerant, as R-32 is an A2L mildly flammable refrigerant requiring specific tools, leak detection practices, and ventilation precautions per ASHRAE 15 and applicable local codes. Disconnect and de-energize all power at the service panel before servicing or connecting the unit. Confirm that line set sizing, refrigerant charge, and static pressure requirements meet Daikin specifications for the matched outdoor unit. Follow all local mechanical and electrical codes, including NEC requirements for disconnect placement and low-voltage control wiring.
