  • Page 7 Features & Benefit MPS(Multi Power System) Variable Control : (Except A2UC146FA0,A2UH146FA0) Big Energy Saving with MPS Variable Control • Basic Principle of MPS Variable Control MPS control provides comfortable and convenient environment as there are two compressors with 60&40% load sharing with on compressor of small capacity always working to maintain the set temperature conditions & meanwhile other compressor is at rest if the load is low whereas in conventional system the only compressor is working with ON/OFF cycles.
  • Page 8 Features & Benefit Air Purifying System (ppm) - It not only removes microscopic contaminants & dust, but it Normal Filter also removes house mites, pollen, and pet fur to help pre- vent allergic diseases like asthma.It provides odor free, dust free and allergy free air.
  • Page 9 Features & Benefit Ultra-Slim design(Depth 129mm) 129 mm Thinnest Turbo Fan 3-Dimensional Cooling System New Cube 3-Dimension cooling system of ART COOL has Indirect Cooling mode for sleep operation. Being in sleep operation, cool air is discharged only right/left side! Indirect cooling ensures you nice sleep.
  • Page 10 Cooling, Heating & Fan Operation: - LG multi air conditioners can provide cooling, heating & fan operation. In the cooling mode, it cools the air with an operation range of 18~30°C. In the heating mode, it heats the air with an operation range of 16~30°C. In the fan operation mode, only indoor fan will run at the selected speed, outdoor fan and compressor will be off.
