Features
- Inverter Technology
- LG's outdoor condensers are designed with efficient inverter technology. An electronic expansion valve and a variable speed compressor carefully regulate the refrigerant flow, reducing energy consumption and allowing for consistent, accurate temperatures.
- Gold Fin Protection
- To ensure the reliability and longevity of the LMU543HV's heat exchanger, LG employs a Gold Fin coating that prevents corrosion and improves durability.
- Low Ambient Operations
- This outdoor unit supports cooling operations down to 14 degrees Fahrenheit and heating operations down to -4 degrees Fahrenheit. There is also a defrost feature, which removes frost from the condenser coil in frigid conditions.
- Quiet Design
- Thanks to a brushless direct current motor and a twin rotary compressor, the LMU543HV is significantly quieter than traditional air conditioning systems. These components reduce mechanical sound, electrical sound, and vibrations within the unit.

- Line Set - This double insulated tubing transfers refrigerant efficiently between your outdoor condenser and indoor units.
- Branch Box - An LG branch box is required to connect this condenser to LG mini split indoor units.
- Drain Tubing - Drain tubing facilitates the reliable and effective removal of condensate from your system. It connects your indoor units to drain locations of your choosing.
- Disconnect Box & Electrical Whip Kit - The Disconnect Box & Whip Kit provides a safe and simple way to connect your outdoor condenser to your fuse box.
- Connecting Wire - This durable, insulated wire provides power to your indoor units from your outdoor condenser.
- Outdoor Condenser Plastic Pad or Wall Bracket - We recommend outdoor condensers should not be placed directly on the ground. An outdoor condenser pad or wall bracket will provide a stable way to mount your condenser free from obstructions and debris. Adding these accessories to your order will provide a complete, ready-to-install mini split system.
LG's devotion to providing efficient ductless solutions can be seen in their Multi F MAX outdoor condenser. The LMU543HV is a multi-zone mini split outdoor condenser capable of supplying ductless heating and cooling for up to eight rooms in your home. With inverter technology and nearly two dozen compatible indoor units in a variety of styles, the LMU543HV is a great choice for nearly any applications.
