Product Features 2
The 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 method
The 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 function
The 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 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, 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

Product
Features
Infrared water level detection sensor
The 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 reinforcement
The safety features of the product have been enhanced in order to prevent various problems from
function when an abnormality in the system is detected.

Product Features
Power saving function
Selecting 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 dispensing
This 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 spout
Ambient 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 function
This provides customers with a convenient reminder that a system setting has been changed via
beeping (ding~, dingdong~, etc.).
Noise prevention
This 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.
