Features
    LG's devotion to providing efficient ductless solutions can be seen across the Multi F line. This ceiling cassette ductless heat pump system pairs a powerful LMU540HV outdoor condenser with very efficient ceiling cassette indoor units. LG's Multi F ceiling cassette indoor units feature four air outlets which allow them to provide consistent air flow to the farthest reaches of large rooms. In addition to providing excellent coverage, the ceiling cassette indoor units also feature an exceptionally low profile. When installed, a grille less than 1" thick is the only visible clue that your room is receiving efficient heating and cooling from a ductless heat pump system.
  • 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 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 with a wind baffle, 0 degrees Farenheit. In heating operations, the unit can handle down to -4 degrees Fahrenheit.
  • 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.
  • Jet Cool
  • These LG mini split indoor units feature a Jet Cool operation mode for rapid cooling. In this mode, an indoor unit observes a set point of 64 degrees Fahrenheit while the fan operates at maximum speed for 30 minutes to quickly cool your zone.
  • Swirl Wind Mode
  • Exclusive to ceiling cassette models is Swirl Wind, which automates both air flow direction and fan speed to produce steady comfort throughout any zone.
  • 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 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.
  • Recommended line set sizes for indoor unit connectivity:
  • LCN127HV4-NOGRILLE: 1/4" x 3/8" Line Set
  • LMCN077HV-NOGRILLE: 1/4" x 3/8" Line Set (Qty 2)
  • LMCN185HV-NOGRILLE: 1/4" x 1/2" Line Set
  • 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)
    • (1) LG - 18k BTU - Ceiling Cassette - For Multi-Zone - Grille Sold Separately (LMCN185HV-NOGRILLE)
    • (1) LG - 12k BTU - Ceiling Cassette - For Single/Multi Zone - Grille Sold Separately (LCN127HV4-NOGRILLE)
    • (2) LG - 7k BTU - Ceiling Cassette - For Multi-Zone - Grille Sold Separately (LMCN077HV-NOGRILLE)
    • (4) LG Multi F Four-Way Ceiling Cassette - Ceiling Cassette Grille (PT-UQC)
    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 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. 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.
