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 KUSXA361A 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

1. High Capacity & Wide Ambient Range
   The unit provides strong cooling and heating output, and works even in cold conditions (down to around -13°F), which is excellent for climates with chilly winters.
2. Good Efficiency
   SEER2 ~18.2, EER2 ~13, decent HSPF2 (~9.6) — means reasonable running costs for a 36,000 BTU outdoor unit.
3. Durability Features
   Gold Fin coating helps with coil longevity (less corrosion, better long-term service), and the base pan heater prevents damage from condensate freeze.
4. Flexible Installation
   Long permitted line run (~246 ft) gives flexibility for indoor / outdoor placement. R-32 gas, modern features like leak detection, etc., add safety and future-proofing.
5. Quieter than Many Large Units
   While 54 dB isn’t silent, for a unit of this size it’s fairly moderate; the use of inverter tech and better compressor design helps reduce noise relative to older styles.

Cons

1. Size, Weight, & Power Requirements
   This is a large, heavy unit. Needs substantial electrical supply (208-230 V, appropriate breaker, wiring), solid mounting pad etc. The upfront installation cost will be nontrivial.
2. Noise Can Be Noticeable Nearby
   In quiet residential areas or near bedrooms, even 54 dB may be perceptible. Placement (distance, orientation, vibration isolation) becomes important.
3. Performance Gradient in Extreme Cold
   Like most heat pumps, heating capacity reduces as outdoor temperature drops far below rated conditions. If you live in very cold regions, auxiliary heat may be needed.
4. Only Part of the System
   This is just the outdoor condenser. You’ll need a matching indoor unit, line sets, controls, and proper installation labour. Total system cost will be significantly higher.
5. Upfront Investment
   Cost of purchase + installation is high; payback depends heavily on usage, energy costs, and climate.

Conclusion

The LG KUSXA361A is a strong, well-rounded choice for someone looking for a large single-zone outdoor mini-split condenser with robust heating and cooling, able to perform well in colder climates. Its efficiency, durability, and flexible installation options make it very appealing for homes or spaces where you want good performance year-round.
