Features
- Inverter Technology
- LG's multi-zone outdoor condensers are designed with powerful, efficient inverter technology. An electronic expansion valve and a variable speed condenser compressor carefully regulate the refrigerant flow, reducing energy consumption.
- Gold Fin Protection
- To ensure the reliability and longevity of the LMU303HV'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.
- Improved Air Quality
- All of LG's wall mounted multi-zone mini split indoor units keep your air clean with a washable anti-fungal filter.
- 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
- With built in Wi-Fi, you have the ability to control your LG air conditioner with smart enabled devices. Simply download the SmartThinQ® app on your smart device to get started.
- Dehumidify
- LG's mini split 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.
- Recommended line set sizes for indoor unit connectivity:
- LMN078HVT: 1/4" x 3/8" Line Set (Qty 2)
- LMN248HVT: 1/4" x 1/2" 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.
- 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.
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 LMU303HV 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.

The U.S Department of Energy has raised the minimum rating requirements starting in 2023 that include updated testing conditions and metrics to better reflect real-world conditions. SEER2 (Seasonal Energy Efficiency Ratio) is a measurement of cooling efficiency over a typical cooling season. It is useful for comparing energy efficiency of cooling systems. The higher the SEER2, the more energy efficient the system.
