Ruud RF2TY2421STANSJB10 Wall Hung Air Handler 2 Ton R454B

Product Description

The RUUD RF2TY2421STANSJB10 is a wall-hung air handler rated for 1.5 to 2 nominal tons with a 24,000 BTU/h capacity. It is engineered to operate with R454B refrigerant, a lower global-warming-potential alternative to R-410A, and is compatible with 208/230-volt single-phase power supply. The unit includes an integrated 10kW electric heat kit, making it a complete heating and cooling air-side solution. A front-return configuration allows installation in wall recesses or tight utility spaces where duct access from the front is required. Licensed HVAC technicians install this unit in residential and light-commercial split systems.

This air handler suits residential new construction and retrofit applications where wall-hung installation is necessary due to space constraints. The front-return design makes it well suited for closet or alcove installs where a traditional bottom or rear return is not practical. At 1.5 to 2 tons nominal, it fits smaller residential zones, individual rooms, conditioned spaces, or supplemental zoning applications that require a compact, self-contained air-handling solution with electric heat.

Key Features

• R454B refrigerant compatibility aligns with current low-GWP refrigerant regulations and next-generation equipment requirements
• 24,000 BTU/h nominal capacity covers 1.5 to 2 ton system configurations
• Integrated 10kW electric heat kit provides supplemental or primary heating without a separate heater package
• Wall-hung, front-return orientation enables installation in space-restricted residential closets and alcoves
• 208/230-volt dual-voltage compatibility simplifies installation across varying residential electrical services

Compatibility

Designed for use in R454B split-system applications rated at 1.5 to 2 nominal tons. Pair with a compatible R454B outdoor condensing unit. No specific outdoor unit model numbers were provided in the product data.

Installation Notes

Installation must be performed by a licensed HVAC technician certified to handle A2L refrigerants, as R454B carries a mild flammability classification requiring adherence to current ASHRAE 15 and local mechanical code requirements. Disconnect and lock out all electrical power at the breaker before any service or installation work. Confirm supply voltage matches the unit nameplate before energizing. Verify that the wall mounting structure provides adequate load-bearing support for the hung cabinet weight before final mounting.
