Water purification system providing an integrated ice making function
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. With an ice making mechanism
featuring an ice tray which utilizes the freezing point method as well as reverse osmotic water purification.
(Patent application: No.2005-99663, 2005-365293, 200510127096.9, 11/342,117)
24 Hour natural water circulation system (N.W.P.W.)
This function of ChungHo purification systems is designed to allow water to continuously flow for 24
hours within the water purifier by adopting a natural circulation method. This mode, entitle 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 purified water to the ice making unit. The freezing point principle states that purest water freezes at 0℃ while non-pure water will
freeze at a temperature below that.
Energy saving function
The economically designed Iguassu Ice delivers purified water to the ice making unit in order to make
pure ice while simultaneously sending cooled water to 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 application. This addition has been integrated into the already stellar system with customer convenience in
mind. The easy-to-use sensor application allows for effortless and enjoyable drinking water with ice.
6
Infrared water level detection sensor
With improved detection accuracy, as compared to existing mechanical detection types, the infrared
OLC sensor applies an electronic water level sensor that was developed for stable water level detection. The signal is connected to a controller in order to automatically adjust purified water levels.(Patent: No.426182)
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 ice making environment.
4 H₂O(Ambient water/Cold water/Hot water/Ice) 1 product!
With improved convenience, the Iguassu ice offers more production and supply power by providing
purified ambient water, cold water, hot water, and ice from the same product.
Product
Features
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 a furthered safety procedure, you will find 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 off the hot water even though 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
occurring. 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.
7
Power saving function
Selecting the power saving function during hot water operation activates the light detection sensor which functions in accordance with the levels of light around the water purifier. By activating the
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 development, 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.
Product
Features
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 satisfaction in preferred temperature from the first drink.
8
Beep function
This provides customers a convenient reminder that a system setting has been changed as sounded
via beeping(ding~, dingdong~, etc.) and as applied via system touch sensors.
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.
Convenience in use
Function operations are designed as simply as possible in order to maximize convenience.
Environment Friendly Coolant
The Iguassu Ice has adopted an environmentally friendly cooling system in the new R-134a, a coolant
that will not add to the problems of ozone layer destruction and global warming.
Default function
Designed to automatically convert to cold water mode when in queue.

When the product is installed in a dark place, and the power saving function is set, then hot water
system may not operate even during daytime. (Install it at bright place.)
Use the following water quality ramge.
- Water Pressure : 7~120 psi (0.5~8.4 kgf/cm2)
- Water Temperature : 39 ~ 100°F (4~38°C)
- pH : 5 ~ 10 - Hardness : 300 ppm or less - Evaporation remains : 500 ppm or less
- Water Quality : Biologically safe water quality
If you do not use water quality within the above range without prior discussion of our company, the
product can be excluded from the stated warranty period.
When transporting the product, do not tilt it over 45°.
Severe tilting can be the cause of reduced performance.
A bad wall outlet or plug may cause an electric shock or fire, do NOT use them.
Do not connect hot water(over 100°F) to this product.
Leave approximately 8 in, between the wall, sides and rear surfaces of the product so that
ventilation may be smoothly performed for safe operation of product.
When connecting tubing hose, take care so that the tubing hose is not be bent or pressed down
by heavy objects, etc
If tubing hose in blocked, water does not flow smoothly and may cause malfunction of the product.
Adjust the hose so that the water discharged from the drainage hose may not splash onto the
product’s surroundings.
Brine water, or the water coming out through drainage lines, can easily be applied towards other water related needs, such as in bathroom cleaning, house cleaning laundering, washing, etc. in order to
prevent waste of water. However, never use the brine water as drinking water or for cooking of food.
Raising the brine water and drain water over 1 ft. above the installation surface, or connecting
them over 6 ft. away from the water purifier can hinder a smooth drainage process. In order to
install the product in a location where the brine water and drained water line are located a distance of over 6 ft. from each, the user will inevitably have to install a separate drainage pump.
8
When installing another product (water purifier, shower softener, etc.) at the same location and
the water is derived from the same installation source, prepare an independent drain line for
each product.

10-6 Understanding the Ice Making Process and Operation
The ice making system of the IGUASSU ICE automatically operates according to designed program
settings after applying power to the product.
1
2
3
If power is supplied to the product by inserting the power plug, then ice making automatically operates without any manual setting.
Upon the initial application of power, if the level of purified water goes above proper operating levels,
then all the ice created from the machine will be automatically removed by deicing action.
In order to be produced 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
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.
Product
Usage
Ice making action
This refers to the making of ice by way of an ice tray by supplying cold refrigerant onto the ice
tray as it is filled with water.
22
Harvest action
This refers to an action to separate the ice created in the ice tray by supplying hot refrigerant
onto the tray.
5
When the ice storage house 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 house.
7
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).
