Product Features 2The Iguassu Ice is designed for both convenience and practicality, as it utilizes compact ice making system, designed to obtain cold water for the production of lice. The system features an ice making mechanism featuring an ice tray, which utilizes the freezing point method as well as reverse osmosis water puri�cation.(Patent application: No.2005-99663, 2005-365293, 200510127096.9, 11/342,117)

24 Hour natural water circulation system (N.W.P.W.)

applies the natural weight of water pressure in order to always supply clean and fresh water.(Patent: No.105585)

Pure ice production utilizing the freezing point methodThe Freezing Point Method produces only the purest ice by supplying puri�ed water to the ice making mechanism. The freezing point principle states that the purest water freezes at 32°F while unpuri�ed water will freeze at a temperature below that.

Energy saving functionThe economically designed Iguassu Ice delivers puri�ed water to the ice making unit in order to make pure ice while simultaneously sending cooled water to the cold water tank. This allows the system to maintain a constant cold water temperature, thus inherently preventing water waste and helping to conserve energy.

Automatic ice dispenserUpon 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 applicationBreaking away from traditional button applications, the Iguassu Ice has a built- in touch sensor appli-cation. This addition has been integrated into the already stellar system with customer convenience in

Infrared water level detection sensorThe Infrared Capacitive Water Level Sensor is applied in the IGUASSU ICE 700. 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 puri�ed water levels.

Automated operation via sensor and micom

4 Functions (Ambient Water, Cold Water, Hot Water, Ice) in 1 Product!

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 ice making environment.

Standard hot water safety function (Hot water locking function + Hot water automatic selection / Release function)Setting the hot water locking function using the Hot Lock touch sensor button prevents hot water from being dispensed from the unit. This is in order to prevent burns and other unwanted injuries to children, the elderly and any other vulnerable user. As an additional safety procedure, you will �nd that upon the use of hot water and the releasing of the hot water lock, the system, after a certain period of time, will automatically shut o� the hot water although the hot water release button has been pressed.

System Display functions and safety reinforcementThe safety features of the product have been enhanced in order to prevent various problems from

function when an abnormality in the system is detected.

Power saving functionSelecting the power saving function during hot water operation activates the light detection sen-

power save function, the user will ultimately reduce power consumption at night.

Automatic water dispensingThis system function is convenient to the user because it enables ambient water, cold water, and hot water to be taken at the press of a button and placed into a container of any kind. Another new de-velopment, found in the Iguassu Ice, is the automatic selection of cold water. In many circumstances, cold water is found to be the most desired temperature of water for drinking. The system has a reset function which, shortly after selecting hot or ambient water, will automatically switch the cooler into cold water mode.

Separate water delivery from a single spoutAmbient water, cold water, and hot water come out from a single spout, but independent water hoses are applied so that ambient water, cold water, and hot water are not mixed, improving overall satisfac-

Beep functionThis provides customers with a convenient reminder that a system setting has been changed via beeping (ding~, dingdong~, etc.).

Noise preventionThis reduces system operating noise by applying a dual noise prevention material, utilizing a shock mitigation structure found at ice storage house, etc.

Wire condenser(Natural convection)Using natural convection, the system wire condensers are rated to reduce noise and thus provide further convenience for the user.

The ice making system of the IGUASSU ICE 700 automatically operates according to the designed program settings when power is applied to the unit.

When power is supplied to the product by inserting the power plug, the ice making process automatically operates without any manual setting.

then 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.

If cold water production is operating properly, the ice making system will produce the ice according to the given water supply.

Water supply action This refers to an action to supply about .25G(1ℓ) of cold water every 50 seconds into ice making mechanism in order to make ice.

Ice making action This refers to the making of ice by way of an ice tray by supplying cold refrigerant onto the ice

Harvest action This refers to an action to separate the ice created in the ice tray by supplying hot refrigerant onto the tray.

When the ice storage house is full, the ice detection sensor will automatically stop the process.

Cold temperature control is applied to prevent ice cubes from melting by periodically sending cold airinto ice storage house.

If ice in the storage house 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.

The lower the surrounding temperatures, the shorter the ice making process will become and the higher the surrounding temperatures, the longer the ice making process will become.

Do not install or use the product in temperatures below 32°F(0°C) and above 100°F(38°C).
