The system features an ice making mechanism featuring an ice tray, which utilizes the freezing point method as well as reverse osmosis water purification. (Patent application: No.2005-99663, 2005-365293, 200510127096.9, 11/342,117) 24 Hour Natural Water Circulation System (N.W.P.W.) natural weight of water pressure in order to supply clean and fresh water at all times. (Patent: No.105585) Pure Ice Production Utilizing the Freezing Point Method The Freezing Point Method produces only the purest ice by supplying purified water to the ice making mechanism. The freezing point principle states that the purest water freezes at 32°F while unpurified water will freeze at a temperature below that. Energy Saving Function The IGUASSU ICE 500 is an energy-efficient product. It delivers purified water to the ice making system in order to make pure ice while simultaneously sending cooled water to the cold water tank. It allows the system to maintain a constant cold water temperature, thus inherently preventing water waste and helping to conserve energy. Automatic Ice Dispenser Upon pressing the ice dispenser touch sensor button, the system then slowly rotates the ice storage plate via an integrated motor in order to automatically replenish the ice supply within the storage housing. Touch Sensor Application Breaking away from traditional button applications, IGUASSU ICE 500 has a built-in touch sensor and ice. 4 Infrared Water Level Detection Sensor The Infrared Capacitive Water Level Sensor is applied in the SUPER IGUASSU ICE 900. It provides more improved detection accuracy than traditional mechanical detection sensors, 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 & Hot Water Locking Function) Setting the safety function using the LOCK/ICE touch sensor button prevents ice cubes and hot water from being dispensed from the unit. It helps to prevent again burns and other unwanted injuries to children, the elderly and any other vulnerable user. Continuous Water Dispensing Mode* The IGUASSU ICE 500 has a continuous water dispensing function, which allows users to dispense cold/ambient water continuously. The system maximizes user convenience since a set volume of water, can be dispensed at the touch of a button. *Not available for hot water. Automated Operation via Sensor and Micom This system internally provides temperature control for the ice making process/cold water process by way of an ice detection sensor, so that ice making, ice removal, and cold water operation, via Micom, may be automatically controlled in order to maintain an optimum operation. Product Features 4 Functions (Ambient Water, Cold Water, Hot Water, Ice) in 1 Product! Separate Water Delivery from a Single Spout Ambient, cold, and hot water are dispensed from a single spout, but independent water hoses are applied so that the different temperatures is not mixed, thus improving overall satisfaction in preferred temperature from the first drink. 5 Noise Prevention 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 when an abnormality in the system is detected. Automatic Water Dispensing The system is convenient to the user because it enables ambient water, cold water, and hot water to be taken at the press of a button. Beep Function It provides customers with a convenient reminder that a system setting has been changed via beeping (ding~, dingdong~, etc.). ProductFeatures Wire Condenser (Natural Convection) Using natural convection, the system wire condensers are rated to reduce noise and thus provide further convenience for the user. 6 Adoption of New Coolant - The IGUASSU ICE 500 has adopted an environmentally friendly cooling system using the R-134a coolant. Default Function Cold water, which is most frequently used, is the system’s default setting. Also, the system is designed to automatically convert to cold water mode when in queue.

(Note: When drain switch is turned ON, water purification and ice making are disabled.) 15 23 NDERSTANDING THE ICE MAKING PROCESS AND OPERATION The ice making system of the SUPER IGUASSU ICE 900 automatically operates according to the designed program settings when power is applied to the unit. 1 2 3 When power is supplied to the product by inserting the power plug, the ice making process automatically operates without any manual setting. When the level of purified water goes above proper operating levels, all the ice created from the machine will be automatically removed by deicing action. In order to produce cold water, the compressor and circulation pump must operate properly. (The cold water production process automatically operates according to designated programming.) Cold water operation This refers to an operation that makes cold water by continuously circulating and supplying water into the cold water tank. Water temperature in the cold water tank is automatically checked by the cold water temperature sensor, and if it drops below the set temperature, then the cold water operation will automatically stop. 4 If cold water production is operating properly, the ice making system will produce the ice according to the given water supply. Water supply action To supply about .25G(1ℓ) of cold water every 50 seconds into ice making tray in order to make ice. Ice making action ProductUsage Harvest action To an action to separate the ice which was made in the ice tray by supplying hot refrigerant onto the tray. 24 5 When the ice storage is full, the ice detection sensor will automatically stop the process. 6 Cold temperature control is applied to prevent ice cubes from melting by periodically sending cold air into ice storage. 7 If ice in the storage is not used for long periods of time, it may melt, and during ice dispensing, small ice cubes can come out. * TDSs(Total Dissolved Solids) of ice may increase according to the environment in which the ice is created. • Cold water will operate as normal even with the ice making function turned off. • The lower the surrounding temperatures, the shorter the ice making process will take and the higher the surrounding temperatures, the longer the ice making process will take. • Do not install or use the product in temperatures below 32°F(0°C) or above 100°F(38°C). 11 PCB Diagrams 이과수 얼음 냉온정수기 500 ͑͢͢͟;ΒΚΟ͑愕 ͑͢͢͟;ΒΚΟ͑愕 ΁ΠΨΖΣ͑΁ʹͳ͑柦笾壊 ΁ΠΨΖΣ͑΁ʹͳ͑柦笾壊 Main Main PCB PCB 11-1 MAIN PCB v CN9 적색 물받이스위치 Red Drip Tray Switch Sensor POWER PCB 백색 White CN1 Main PCB White CN17 백색 누름 Press버튼 Button CN6 WHT 토출 DOOR Discharging Door 12V BB출력 Output AA출력 Output BOutput B-출력 AOutput A-출력 GND Signal CN12 CN7 GND 1 Black 흑색 ICE만빙센서 Full Sensor Signal 2 GND 1 CN8 청색 Blue 5V 2 ICE만빙센서 Full Sensor Signal 3 CN10 청색 Blue 1 Signal 2 5V CN16 DC12V 1 White 백색 Signal 2 GND 3 PCB Diagrams CCW-Ice making CCW-제빙 GND 주위온도센서 Environ.
