7. Guide to Operating the Ice Maker
Fig. 10 Switch
Fig. 11 Ice cube
Initial operation
① Open the water supply valve connected with the ice maker.
② Insert the plug of the ice maker into the electric outlet.
③ Open the door and turn the switch at the lower end of the
product to the “ICE” position.”
④ Discard the first batch of ice.
⑤ Good-quality ice is produced 1-2 hours later.
Using the ice maker
Use of the ice maker is very simple. Simply turn the switch at
the lower end of the product to the “ICE” position.
The product automatically starts ice production, which continues
until the ice container has been filled with ice. Remove the ice
using an ice gourd and insert the gourd into the holder on the
inside of the container (If you place the container in the ice,
it may be covered over by ice).
The ice maker produces 24 pieces of ice every 30 minutes.
Also, the produced ice drops down into the ice container;
water is supplied to the ice maker and the water is also
drained.
Important Information : Do not put anything other than
ice in the ice container. Wine or beer bottles are unsanitary
and a detached label may block the drain pipe.
Ice
The ice has a rectangular bell shape (refer to the figure).
Newlyproduced ice is clear and transparent. The inside of the ice
is sometimes cracked; however, such cracks commonly occur in
the production process and disappear with time.
Ice stored in the container for a long time may gather frost on
the outside and look muddy. This is normal ice and, once water
is poured on the ice, such frosting disappears.
Ice container
The product continues making ice until the level of ice reaches
the temperature sensing tube(right side). It then ceases operation.
The model with a drain pump drains away melted ice when the
ice maker is turned off. The pump works for only several seconds.

16
Operation time
It takes about 20-35 minutes to produce a set of 24 ice pieces. The length of one cycle
of the ice maker (ice production and ice removal) differs depending upon the cleanness
of the ice maker, the surrounding temperature, and the temperature of the water supplied
to the ice maker. It takes about 10-12 hours to fill the empty ice container with ice.
Ice production
The ice production process largely consists of two cycles-ice production and ice removal.
24 pieces of ice are produced with each cycle of ice production and ice removal.
When water is sprayed on to the surface of the frozen iceforming mold, the ice production
cycle is started. When ice is removed and water is supplied to ice maker, the ice removal
cycle is started. The time taken for both cycles together is about 20-35 minutes.
Ice production cycle
As the ice production cycle progresses, the compressor exhausts the refrigerant, the fan
motor circulates the air, and the pump motor circulates water. When the surface of
the ice-forming mold absorbs the heat from the water, the heat moves to the part to
which the fan supplies water. The heat is transferred to the air and the heated air is
removed from the ice maker. At the same time, ice is produced on the surface of the ice
-forming mold (at the upper end of the ice maker). When the surface of the ice-forming
mold has sufficiently cooled, the ice production cycle stops and ice removal is started by
the program installed in the ice maker.
Ice removal cycle
The compressor works during the progression of the ice removal cycle, but the pump motor
and fan motor are stopped. The hot gas valve and water supply valve work. When the two
valves are opened and the frozen surfaces are heated, ice drops down into the container.
Then the ice removal cycle is stopped and the ice production cycle is started again by
the program installed in the ice maker.
How to use water for ice maker
The ice maker starts its work with the fixed quantity that has been fed into the water
container. When water is sprayed on to the surface of the ice-forming mold, the water not
containing mineral impurities freezes and attaches to the ice-forming mold. The water
containing impurities drops down into the water container. During the progression of the ice
production cycle, the mineral impurity level in the water in the water container rises.
During the progression of the ice removal cycle, water is fed to the ice maker, thereby
diluting the water in the container, and washes a part of the concentrated minerals
through the drain pipe.

[ Cautions for cleaning the external panel(stainless steel) ]
※ How to remove rust
How to clean rusted parts
1. Rust spots in early stage
- Rust spots in early stage mean that the stainless steel itself is not severely affected,
thus mild detergent or any commercially available cleaning agent will restore original
state. Rust will be removed with ease and at low cost if regular cleaning is done
at appropriate intervals.
2. Red rust
- Rust spots that are not removed after a short period of time will turn into thick reddish
-brown rust and will damage the surface of the stainless steel. These are much harder
to remove and the surface will not be fully restored; thus, it is important to remove rust
spots early on.
If commercially available cleaning agents do not work, use sandpaper or a stainless
steel brush to remove the rust before applying the agent for easier removal.
This process requires treatment, such as refurbishment after cleaning.
3. Rust from iron
- Rust from coming into contact with welding spatter, rust from the metal bar above
the stainless steel part, or contact between the stainless steel parts and general metal
parts are caused galvanic corrosion. This causes the metal to rust first, and it will
eventually cause the stainless steel to rust too if it is not removed. As such, make sure
to clean and remove rust immediately with a mild detergent. However, when the rust
has gotten really bad, it must be removed with 15% nitric acid solution
or commercially available stainless steel cleaner.
4. Rust from exhaust gas or acid rain
- In environments, such as a factory complex or heavy transport sites, the product
will become contaminated in a short amount of time due to exhaust fumes or acid rain
and rust spots will quickly form. Light rust can be washed off with a mild detergent or
soapy water, but heavy rust will require 15% nitric acid solution or commercially available
stainless steel cleaner.
5. Rust from salt deposit
- In environments, such as windowsills or pipes on the porches of an apartment complex,
that are close to the seashore where the product may be directly exposed to the sea
winds, STS304 or STS316 will get rusted in no time, and this will occur much faster
than in other types of environments. These cases require special treatment, such as
using painted stainless steel or regular cleaning.
6. Rusts from disinfectants or cleaning agents
- Sites, such as pools or public baths, that use chlorine-based agents to sterilize the water,
especially those for cleaning bathrooms, contain chlorine content that attaches to
and rusts the stainless steel surface. Thus, it is important to thoroughly wash off such
agents after using them, and a 15% nitric acid solution or commercially available
stainless steel cleaner are required for removing this type of rust.

1. Empty the ice tank and prepare a cleaning
solution by distilling 30g of neutral
dishwashing detergent with 8L of warm water
(35~45℃). Soak a clean cloth in the solution
and clear the inside of the ice tank.
Pour an appropriate amount of the solution
into the draining pipe, and then wait until
it dries naturally.
* Press the switch to set it to “Ⅱ”(WASH) when cleaning the product;
this will repeat the process of supplying water for about 2 minutes and operating
the circulation pump 3 times, enabling easier cleaning.
