(Patent application: No.2005-99663, 2005-365293, 200510127096.9, 11/342,117) 24 Hour Natural Water Circulation System (N.W.P.W.) ChungHo purification systems are designed to allow water to continuously flow for 24 hours within the water purifier by adopting a natural circulation method. This mode, called N.W.P.W. applies the natural weight of water pressure in order to supply clean and fresh water at all times. - Page 5 Infrared Water Level Detection Sensor Infrared OLC sensor is applied in IGUASSU ICE 500. It provides more improved detection accuracy than traditional mechanical detection types, thus allowing stable water level detection. The signal is connected to a controller in order to automatically adjust purified water levels. (Patent: No.426182) Safety Function (Ice Dispensing &...
- Page 6 Noise Prevention Operating noise level is significantly lowered due to applying a dual noise prevention material, and utilizing a shock mitigation structure at ice storage house, etc. System Display Functions and Safety Reinforcement The safety features of the product have been enhanced in order to prevent various problems. The system will inform the user(s) of abnormal occurrences through a flashing display icon and by automatically stopping the ice making function, cold water function, and water purification function when an abnormality in the system is detected.
