Overview for LG LMU543HV 3-LMN249HVT

LG's devotion to providing efficient ductless solutions can be seen across the Multi F line. This wall mounted ductless heat pump system pairs a powerful LMU543HV outdoor condenser with LG's Standard Indoor line. An easy installation process and low sound levels mean that this system provides temperature control that doesn't disrupt your home. The well-rounded indoor units feature several convenient operation modes and each includes a wireless remote controller, making it easy for you to enjoy zoned comfort.
  • 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.
  • Quiet Design
  • Thanks to a brushless direct current fan motor, both the outdoor and indoor units in this system produce less mechanical and electrical noise, allowing them to provide comfort that doesn't disrupt your home.
  • Air Flow Options
  • This unit gives you two options for automating air flow. In Swing Mode, the unit will rotate through all four air flow directions and with the Chaos Wind feature, it cycles both air flow direction and fan speed.
  • Self-Cleaning Coil
  • These wall mounted indoor units feature self-cleaning heat exchanger coils that automatically remove dirt and moisture. This helps to prevent unpleasant odors and to combat the formation of mold.
  • Jet Temperature Control
  • Getting your zone comfortable quickly is no problem thanks to the Jet Cool mode with these indoor units. With the press of a button, your system will operate at maximum output to provide rapid zoned cooling.
  • Automated Operation
  • Auto operation mode continually compares your zone's current and desired temperatures and uses that data to intelligently adjust fan speed and refrigerant flow to provide optimal comfort.
  • Sleep Mode
  • With the sleep mode and timer functions, you can set the indoor units to save energy at night. Sleep mode will incrementally adjust temperatures for an hour before the timer function automatically deactivates the units.
  • Improved Air Quality
  • These mini split indoor units use a dual filtration system to keep your air clean. A washable anti-fungal filter protects against dust and bacteria, while a 3M Micro Protection Filter captures microscopic irritants for pristine air quality.
  • Dehumidify
  • LG's multi-zone indoor units include a dehumidifying operation mode. In this mode, the unit's internal sensors monitor temperature and modify the set point and fan speed to remove moisture from the air.
  • Hot Start
  • When the hot start function is enabled on a mini split indoor unit, the fan will not engage until the outdoor condenser has had the opportunity to warm the indoor coil. This prevents the unit from blowing cold air during heating operations.
  • Built-In Wi-Fi
  • Built-In Wi-Fi allows you to control your LG air conditioner with smart enabled devices. Simply download the SmartThinQ® app on your smart device to get started.
  • Recommended line set sizes for indoor unit connectivity:
  • LMN249HVT: 1/4" x 1/2" Line Set (Qty 3)
  • Recommended line set size from outdoor unit to branch box:
  • LMU543HV: 3/4" x 3/8" Line Set
  • All LG branch boxes systems require a min of 16.4 feet of line set between the condenser and the branch box, from the branch box to the distribution box and from the distribution box to the indoor unit.
  • Product Note
    Each indoor unit will include any port adapters necessary for multi-zone installation.This product requires the following accessories for installation:Line Set - This double insulated tubing transfers refrigerant efficiently between your outdoor condenser and 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.Base Pan Heater - The base pan heater prevents ice from building up on the outdoor unit. Excessive ice build will lead to performance issues and could damage your unit.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. All Mini Split Systems require one Primary Mini Split Installation Kit. You may also require one or more Secondary Installation Kits if you have a Multi-Zone system. You will need a Secondary Installation Kit for each additional indoor unit.LG products include a 10-year warranty with the requirement that installation is completed by a licensed contractor and that the product is registered at https://lg-dfs-warranty.com/>https://lg-dfs-warranty.com/ within 60 days of installation.
