too high, the quantity of produced ice creams may drop,
it may not be discharged or other malfunctions may
occur. Consult an engineer.
3-4 : Set the mixing tank temperature
This item is used to adjust the cooling temperature of the
ingredients in the mixing tank. The larger the number is, the
higher the storage temperature is.
The smaller the number is, the lower the storage
temperature is. If the temperature is too low,
the ingredients may freeze. If too high, they may spoil.
3-5-1 : Select a voice announcement option
You can turn on/off the voice announcement.
The ice cream level (3-1) may vary according to ingredients or sugar content. If it is high, the
machine operates too much unnecessarily to make the ice cream soft. Also, if the machine
stays in the auto mode for two or three hours without discharging any ice cream, this may
make the ice cream softer depending on the ingredients
17
Making Soft & Spaghetti ice cream
●
The smaller the caburator hole is, the higher the overrun (air content) is.
Instead, in case of continuous sales, the ingredients supply gets slower
and the soft ice cream is let out slowly.
●
The caburator hole can get clogged, so check it and wash it periodically during use.
●
The manufacturer shall not be responsible for any trouble (e.g., spoilage of materials,
overcooling, non-production of ice cream) caused by using materials in non-frozen
state (10℃).
1. Pour 2.0ℓof ingredients in the mixing tank.
The raw material must has been stored in a cooler
at a temperature 10℃ or below.
2. Plug in the caburator and block the hole.
3. Pour 2.0ℓof ingredients in the mixing tank.
open the caburator hole of the caburator tube.
4. See if the insufficient ingredient lamp is
turned off.
and Close the cover.
5. Press the "AUTO" button.

1. Control the bolt below the outlet lever to control
the speed of making ice cream.
As shown in the figure, loosen the bolt by turning
it counterclockwise to speed up the making of ice cream.
2. As shown in the figure, tighten the bolt by turning it
clockwise to slow down the making of ice cream.
※ After setting the bolt, tighten the middle nut “a” to keep
the bolt at that position and stabilize the amount and speed.
● Higher speed by loosening the bolt also means slower supply of ingredient to the cylinder
from the hopper, and ice cream may not come out at a certain point.
Thus, setting the speed at 6~8 seconds is recommended for a cup of ice cream.

A small hole can improve the overrun, but it may depend on the amount of
ingredients in the mixing tank. The fewer ingredient is in the mixing tank, the higher
the overrun becomes.
The more the ingredient is, the lower the overrun becomes.
The caburator is made up of two parts.
The part that is inserted into the hole of the mixing tank is called the
body and a tube is inserted into this. The tube has a hole at the top
and at the bottom. It can’t be inserted in the reverse direction.
The figure shows the caburator with a blocked hole.
If you align the protrusion of the upper area of the caburator body with
the area having no hole in the upper area of the tube, then the hole in
the lower area of the caburator body will be blocked.
Condition of use: Initial soft ice cream making
This figure shows the caburator aligned with a large hole.
Align the protrusion of the upper area of the caburator body with the
large hole in the upper area of the tube. Decrease the overrun and
increase the amount of ingredients injection in this way when you
need continuous vending of the product.
Condition of use: When the “Auto” mode is executed
This figure shows the caburator aligned with a small hole.
Align the protrusion of the upper area of the caburator body with the
small hole in the upper area of the tube. Then, it will be aligned with
the small hole in the lower area of the caburator body. Increase
the overrun and decrease the amount of ingredients injection in this
way when you expect a small amount of sales.
Condition of use: When the “Auto” mode is executed
This figure shows the caburator aligned with a medium hole.
Align the protrusion of the upper area of the caburator body with the
medium hole in the upper area of the tube. Then, it will be aligned with
the medium hole in the lower area of the caburator body. It will make
the overrun and the amount of ingredients injection adequate for sales.
