Daikin FTA48AAVJUA 48000 Btu Mini Split Air Handler R-32

Product Description

The DAIKIN FTA48AAVJUA is a multi-position mini split air handler rated at 48,000 BTU/h, designed for use with R-32 refrigerant systems operating on 208/230V single-phase power. This indoor unit is part of the Daikin SkyAir line and is built for flexible installation in horizontal or vertical orientations, making it suitable for a range of commercial and light-commercial applications. Licensed HVAC technicians install this unit as the indoor evaporator component of a ductless or ducted mini split system, pairing it with a compatible Daikin outdoor condensing unit. The unit measures 21.00 inches wide, 53.40 inches tall, and 21.00 inches deep.

The FTA48AAVJUA is intended for single-zone applications where consistent temperature control across a larger conditioned space is required. Its multi-position design supports installation in mechanical rooms, utility closets, or ceiling spaces where the air handler orientation must adapt to the jobsite layout. Typical applications include commercial office suites, retail spaces, server rooms, and larger residential zones that demand a higher-capacity indoor unit. This model ships without a disconnect.

Key Features

• 48,000 BTU/h cooling capacity for high-demand single-zone applications
• Compatible with R-32 refrigerant, which carries a lower global warming potential than R-410A
• Multi-position installation flexibility - mounts in vertical or horizontal orientation
• 208/230V single-phase electrical supply suits standard commercial and residential service

• Part of the Daikin SkyAir product line, designed for ducted or ductless light-commercial deployment

Compatibility

Designed as an OEM-style indoor air handler for Daikin SkyAir single-zone mini split systems using R-32 refrigerant. Pair with a compatible Daikin outdoor condensing unit rated for R-32 and sized to match the 48,000 BTU/h capacity. Consult Daikin's current engineering submittal documentation to confirm compatible outdoor unit model numbers before installation.

Installation Notes

Installation must be performed by an EPA 608-certified HVAC technician familiar with R-32 refrigerant handling procedures; R-32 is mildly flammable (A2L classification) and requires adherence to applicable local codes and manufacturer guidelines. Shut off and lock out all power to the system before making any electrical or refrigerant connections. Confirm that the electrical supply voltage, ampacity, and overcurrent protection match the unit's nameplate requirements prior to startup. Do not install in spaces where R-32 concentration limits could be exceeded in the event of a refrigerant leak; consult ASHRAE 15 and local mechanical codes for minimum room volume requirements.
