    Features 6RWU0-05B 5. Features The following features can be found in PTAC (Packaged Terminal Air-Conditioners) :- n 2 -Way Air Flow Direction n Indoor Fan Speed Setting n Washable Filters n Two Fan Motors n Low Noise at High Air Volume n LED Diagnostics and Self Diagnostics n High Efficiency Compressor n Indoor Room Freeze Protection...
  • Page 17 Low Noise at High Air Volume New Blowers and Fans which are bigger and stronger than earlier ones operate at low rpm’s and have higher efficiency. High Efficiency Compressor LG Rotary compressors have low noise, low vibration and higher efficiency and reliability. Energy save mode This feature employs a programmable logic which enables the unit to minimize power consumption.
  • Page 18 Features 6RWU0-05B Electric Heater Electric heaters are used in cold regions when instant heating is required in the room. In such cases, electric heaters are preferred over heat pump models which sometimes require long times to achieve the desired heating effect. Electric Heater are of two types –...
  • Page 19 This feature extends the overall life of the compressor by preventing the short cycling of the air-conditioner. When the com- pressor restarts, LG PTAC is designed to give it a minimum of three minutes to have a time of equalizing the refrigerant pressures for optimizing the cycle.
  • Page 20 Formation of ice reduces the airflow through the coil and hence the efficiency of the air conditioning unit. The LG PTHP employs an active reverse cycle defrost function to melt the ice off the outdoor coil for ensuring room comfort conditions and savings from extended operation.
