Overview for LG L4L42C07091212

LG continues to demonstrate global leadership in innovation and technology with their advancements in home comfort solutions. The LGRED° Heat ductless heat pump system boasts superior heating performance in extreme cold weather climates. The powerful LMU420HHV outdoor condenser works with LG indoor units to provide the maximum amount of comfort control for your home. With several air flow options, quiet operation, and weather protection technology, the LGRED° Heat system is accommodating to nearly every home.
  • Integrated Base Pan Heater
  • Base pan heaters come factory installed on all LGRED° outdoor condensers in order to mitigate the risk of damage caused by freezing condensate.
  • Inverter Technology
  • LG's inverter technology features an electronic expansion valve and a variable speed compressor that carefully regulates refrigerant flow, reducing energy consumption and providing consistent, accurate temperatures without overshooting or short-cycling.
  • Gold Fin Protection
  • To ensure the reliability and longevity of the LMU420HHV's heat exchanger, LG employs a Gold Fin coating that prevents corrosion and improves durability.
  • Quiet Design
  • Thanks to a brushless direct current motor and a twin rotary compressor, the LMU420HHV is significantly quieter than traditional air conditioning systems. These components reduce mechanical sound, electrical sound, and vibrations within the unit.
  • Air Flow Options
  • The LG ceiling cassettes feature three air flow options. Swing mode fluctuates air flow direction. Chaos wind cycles direct and fan speed to provide more natural circulation. Finally Swirl mode produces steady comfort though out the zone.
  • Self-Cleaning Coil
  • These wall mount units feature a self-cleaning heat exchanger coil that automatically removes dirt and moisture. This helps to prevent unpleasant odors and to combat the formation of mold.
  • 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.
  • Automated Operation
  • Auto operation mode continually compares your zone's current and desired temperatures and uses that data to intelligently adjust the unit's fan speed and refrigerant flow to provide optimal comfort.
  • Sleep Mode
  • With the sleep mode and timer functions, you can set this indoor unit to save energy at night. Sleep mode will incrementally adjust temperature for an hour before the timer function automatically deactivates the unit.
  • Condensate Protection
  • Condensate overflow can damage your indoor unit and your home. An internal condensate pump with 27.5" of lift protects the ceiling cassette through reliable, effective condensate removal.
  • 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.
  • Improved Air Quality
  • The LG ceiling cassette units use a dual filtration system to keep your air clean. A washable filter is backed up by a plasma filtration system that can attract and capture microscopic irritants for pristine air quality.
  • Hot Start
  • When the hot start function is enabled, the ceiling cassette's 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.
  • Supply Air Branch Duct Connections
  • LG cassette units feature designated cutouts for a branch duct, giving you the ability to duct up to 1/2 of the unit's airflow capacity to adjacent spaces.
  • Recommended line set sizes for indoor unit connectivity:
  • LCN097HV4: 1/4" x 3/8" Line Set
  • LCN127HV4: 1/4" x 3/8" Line Set (Qty 2)
  • LMCN078HV: 1/4" x 3/8" 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.
  • 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.
  • 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
    This product requires at least two compatible LG mini split indoor units and the following accessories for installation:Branch Box - An LG branch box is required to connect this condenser to the LG mini split indoor units.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. 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.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.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/ within 60 days of installation.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.
