Daikin 24,000 BTU Oterra Series Ductless Mini Split Condenser | R32 | Cooling Only

The Daikin RKF24AXVJU Oterra Series condenser is a two-ton outdoor unit designed for single-zone, cooling-only ductless mini-split applications. It is intended for homeowners, HVAC contractors, property managers, and light-commercial buyers who need independent air conditioning for an appropriately sized room or designated area. Typical applications include larger living spaces, offices, additions, studios, finished basements, and locations where traditional duct installation is unavailable or impractical.

This product is the outdoor condenser only. The RKF24AXVJU must be paired with the compatible Daikin FTKF24AXVJU wall-mounted indoor air handler. Refrigerant piping, electrical components, controls, condensate drainage, mounting equipment, and other installation materials are required separately unless specifically included with the purchase.

Although identified in the 24,000 BTU nominal capacity class, published performance data lists a rated cooling capacity of 22,400 BTU. Its variable output ranges from approximately 7,000 to 26,400 BTU per hour. When installed as the verified matched system, the equipment achieves ratings of up to 21 SEER2 and 12 EER2. These efficiency ratings apply to the complete RKF24AXVJU and FTKF24AXVJU combination rather than the outdoor condenser by itself.

Key Features

• Two-ton cooling class: Provides single-zone air conditioning for an appropriately sized residential or light-commercial area
• Cooling-only operation: Designed for spaces that need air conditioning without heat-pump heating
• Variable-capacity performance: Adjusts cooling output within its published range as operating conditions and cooling demand change
• Hermetic swing compressor: Uses Daikin compressor technology designed for inverter-controlled ductless operation
• R32 refrigerant system: Engineered specifically for use with compatible Daikin Oterra R32 indoor equipment
• Direct-drive outdoor fan: Uses a direct-current propeller fan to move air across the outdoor fin-tube heat exchanger

The outdoor fan provides approximately 1,879 CFM of airflow at high speed. Its published sound pressure level is approximately 55 dBA under rated operating conditions. Actual sound can vary depending on system load, placement, mounting method, clearances, surrounding surfaces, and equipment maintenance.

The ivory-white cabinet measures approximately 36-5/8 inches wide, 27-13/32 inches high, and 13-13/16 inches deep. The unit weighs approximately 101 pounds. These specifications should be considered when selecting an equipment pad, approved wall bracket, or outdoor mounting location.

Published system ratings and the verified indoor/outdoor equipment combination are documented in the AHRI certificate for the RKF24AXVJU and FTKF24AXVJU.

Compatibility and Installation Notes

The RKF24AXVJU is designed to match the Daikin FTKF24AXVJU cooling-only indoor air handler. It should not be connected to an unverified indoor unit or the FTXF24AXVJU heat-pump air handler. HVAC365 separately lists the matching FTKF24AXVJU indoor unit.

The condenser requires a 208/230-volt, 60 Hz, single-phase electrical supply. Published specifications list a minimum circuit ampacity of 14.23 amps and maximum overcurrent protection of 20 amps. Final wiring, breaker, disconnect, and grounding requirements must follow current Daikin instructions and applicable electrical codes.

Refrigerant connections are listed as 1/4 inch for the liquid line and 5/8 inch for the gas line. Maximum total piping length is approximately 98-1/2 feet, with a maximum vertical separation of 65-5/8 feet. The unit includes a listed factory R32 charge of 3.31 pounds and supports a chargeless piping length of approximately 32-13/16 feet. Any additional refrigerant must be calculated according to Daikin specifications.

The standard published cooling range is approximately 50°F to 122°F outdoors. Any low-ambient configuration requires the applicable Daikin settings and approved accessories.

Professional installation is required for placement, mounting, electrical work, piping, evacuation, leak testing, R32 refrigerant procedures, and commissioning.

Frequently Asked Questions

Does this condenser provide heating?
No. The RKF24AXVJU is a cooling-only outdoor unit.

Is the indoor air handler included?
No. The matching FTKF24AXVJU air handler is sold separately unless otherwise stated.

Can this condenser operate independently?
No. It requires the compatible indoor unit and all necessary system connections.

Does the system require ductwork?
No traditional ductwork is required, but refrigerant lines, wiring, controls, and condensate drainage are necessary.

How should the correct capacity be selected?
A qualified HVAC contractor should perform a load calculation based on the building and local climate.

Review the matching indoor equipment and installation requirements to determine whether the Daikin RKF24AXVJU fits your cooling project.
