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 LMU541HV'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 brushless fan motors, both the outdoor and indoor units in this system produce less mechanical and electrical noise. A twin rotary compressor in the outdoor unit also limits vibration noise.
- Automated Operation
- Auto operation mode continually compares your zones' 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.
- Condensate Protection
- Condensate overflow can damage your indoor unit and your home. Internal condensate pumps with 27.5" of lift protect these indoor units through reliable, effective condensate removal.
- Improved Air Quality
- These mini split indoor units include anti-fungal filters to keep your air clean. These filters capture contaminants like dust and bacteria, and they are washable to ensure long term air quality.
- Dehumidify
- LG's multi-zone indoor units include a dehumidifying operation mode. In this mode, the units' 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.
- Recommended line set sizes for indoor unit connectivity:
- LMHN240HV: 1/4" x 1/2" Line Set (Qty 2)
- A branch box with a 3/8" x 3/4" line set connection is also required. Additional branch boxes and line sets may be required based on your configuration.
- 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.
- Branch BoxAn 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. We recommend locally purchased PVC hard pipe for the condensate drain on cassette and concealed duct units.
- 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 concealed duct ductless heat pump system pairs a powerful LMU541HV outdoor condenser with two concealed duct indoor units. These units are designed for installation in short-run ducting with high static pressures. With this system, you can add quiet zoned comfort to your home without mounting anything on your walls. Like a central system, small air registers all that your guests will see with this concealed duct heat pump system.
