Features
    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 LMU540HV outdoor condenser with three concealed duct indoor units. These units are designed for installation in short-run ducting with low 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.
  • 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 LMU540HV'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:
  • LMDN186HV: 1/4" x 1/2" Line Set (Qty 3)
  • 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.
  • Product Includes
    • (1) LG - 54k BTU - Outdoor Condenser - For 2-8 Zones (LMU540HV)
    • (3) LG - 18k BTU - Low Static Concealed Duct Unit - For Multi-Zone (LMDN186HV)
    • (3) LG Wired Remote Control Extension Cable - 32 Feet (PZCWRC1)
    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.
    • 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.
    Adding these accessories to your order will provide a complete, ready-to-install mini split system.

What is the maximum length of the tubing from the outside unit to the inside unit?
Anthony 
from New Jersey 
August 15, 2016
Answer
This condenser requires the use of one or more branch boxes. There is a maximum piping to both branch boxes of 180.4 ft. The maximum length to any one indoor unit from a branch box is 49.2 ft. The maximum total line set length is 475.7 feet.

There are more restrictions to be aware of. Please see page three of the LMU540HV Submittal for more details about line set installation requirements.

Can the LG system deliver heat down to 5 degrees? If so, are the BTU ratings listed the same at this temp?
Andrew S. 
from Massachusetts 
July 24, 2016
Answer
LG outdoor units do not shut down based on outdoor temperature*. They will deliver heat at 5 degrees, and lower. However, their output will decrease as temperature drops toward freezing and below. For specific details on capacities at different outdoor temperatures, you can reference the Engineering Manual. If you need any help interpreting the manual, feel free to email or call us.

*The units will shut down if operating pressures in the systems are unsafe. Once pressures return to safe levels, the units will resume operation.
