LG continues to demonstrate global leadership in innovation and technology with their advancements in home comfort solutions. The LGRED° Heat ductless heat pump system boasts superior heating performance in extreme cold weather climates. The KUSXA241A is a single zone mini split outdoor condenser capable of supplying ductless heating and cooling to any room in your home. With inverter technology and quiet operation this well-rounded mini split outdoor condenser is an easy choice for any system.

• Gold Fin Condenser
• Inverter Technology

Enhanced Connectivity

LG's new R-32 mini split units require a 5-conductor cable (Not Included) instead of the standard 4-conductor, improving communication reliability and enabling a new leak detection feature.

Low Ambient Operations

This outdoor unit supports cooling operations down to 5 degrees Fahrenheit and heating operations down to -13 degrees Fahrenheit. There is also a defrost feature, which removes frost from the condenser coil in frigid conditions.

Integrated Base Pan Heater

Base pan heaters come factory installed on all LGRED° outdoor condensers in order to mitigate the risk of damage caused by freezing condensate.

Quiet Design

Thanks to a brushless direct current motor and a twin rotary compressor, the unit is significantly quieter than traditional air conditioning systems. These components reduce mechanical sound, electrical sound, and vibrations within the unit.

Frequently Asked Questions

Q: What are the operating temperature ranges?

A: The unit operates in:

• Cooling Mode: Operates between 5°F and 118°F
• Heating Mode: Operates between -13°F and 64°F

Q: What are the key features of the LGRED Single Zone Mini Split Outdoor Condenser Unit?

A: Notable features include:

• High efficiency with inverter technology, a variable-speed compressor, and an electronic expansion valve for precise refrigerant control.
• Quiet operation, using a brushless DC motor and twin rotary compressor to reduce sound and vibration.
• Enhanced durability via a corrosion-resistant Gold Fin™ coating on the heat exchanger.
• Cold climate readiness, including a factory-installed base pan heater to prevent freezing and damage.
• Smart connectivity, requiring a 5-conductor cable for stable communication with the indoor unit and featuring built-in leak detection.

Q: What accessories are required for installation?

A: The following components are typically needed:

• Line set: Double-insulated tubing for refrigerant flow
• Drain tubing: For removing condensate
• Disconnect box and whip kit: For electrical connection to your home’s fuse box
• Connecting wire: To deliver power and signals from the condenser to the indoor unit
• Outdoor condenser pad or wall bracket: To keep the unit off the ground and ensure stable mounting

Q: What are the electrical requirements for this unit?

A: Electrical requirements are:

• Voltage: 208–230V
• Phase: Single-phase
• Frequency: 60Hz
• Wiring for Outdoor Unit (ODU): 3 x 12 AWG cable required

Q: How does inverter technology improve performance?

A: Inverter technology uses a variable-speed compressor to continuously adjust refrigerant flow, maintaining consistent temperatures and eliminating energy-wasting on/off cycles. This provides better comfort and energy efficiency than traditional systems.

Q: What is the purpose of the Gold Fin protection?

A: The Gold Fin coating on the heat exchanger prevents corrosion, extending the lifespan of the unit—especially beneficial in coastal or high-humidity environments.

Q: How does the base pan heater function in cold climates?

A: The factory-installed base pan heater prevents water from freezing in the drain pan. This helps protect the unit and ensures reliable operation in sub-freezing temperatures.

Pros

• Good capacity for rooms/areas that are medium to large—24,000 BTU cooling + 27,000 heating gives solid performance.
• Efficient operation thanks to good SEER2/EER2/HSPF2 ratings; lower running costs in many climates.
• R-32 refrigerant and leak detection help make the unit more environmentally conscious and safer.
• Quiet operation especially at lower fan speeds—less disruptive indoors.
• Useful features like auto-restart, sleep mode, timer give better convenience.
• Flexible piping length helps if indoor and outdoor units are far apart.

Cons

• While efficient, SEER2 of ~17.5 is good but not top-tier; in very hot climates or for extreme efficiency goals, higher rated units may perform better.
• Headroom for heating drops at very low ambient temperatures; performance may degrade when it’s extremely cold.
• Installation cost and complexity can be higher: needs proper electrical supply (voltage, breaker), professional setup, plus indoor unit + mounting.
• Outdoor unit will have some noise, especially on high settings; may be noticeable outdoors or nearby.
• Upfront cost (equipment + installation) is significant; payback depends on usage and climate.

Conclusion

The LG KUSXA241A is a strong, well-balanced mini-split condenser for applications where you need both cooling and heating capacity in moderate to large spaces. It strikes a good mix of performance, efficiency, and modern features (leak detection, remote modes etc.).
