Check prior to use
【 The following must be checked before using the product! 】
Install it independently with an earth leakage circuit breaker with more than 20A
and provide anexternal grounding.
(Ask a qualied electrical technician for the installation.)
The power cable should be connected before the product can operate normally.
The air suction and discharge should be facilitated so that the cooling performance
can be optimized.
Do not skip filter cleaning to ensure good-quality ice cream.
The daily cleaning of the cylinder, carburetor, hopper, agitator, dasher, piston, and other parts
is recommended.
The condenser has to be cleaned more than once a month.
The cylinder, mix tank, impeller, dasher, and piston inside the product make contact
with the ingredients, so you should clean them once every day.
● Do not block the air vent.
● Regular filter cleaning (at least once a week)

Functional description of the buttons
If you press the "Set" button lightly, you can
enter the mode to check the setting as below.
Use the“▼”and“▲”buttons to see the settings.
1-1: Check ice cream level settings
You can check the current setting for the ice cream. If the
displayed value is higher than the no-load current (1-2),
the ice cream becomes harder and if lower,
the ice cream becomes softer.
1-2: Check the ice cream default level
It is the no-load current of the dasher motor.
It is the current consumed by the dasher motor when the
ingredients are in the liquid status.
1-3 : Check the currently supplied voltage.
It is the power supplied to the machine.
If the voltage is not correct after installation,
call for service.
1-4 : Check the storage temperature in the mixing tank.
You can check the temperature inside the mixing tank.
1-5 : Check the voice announcement
You can check whether a voice announcement is available.
1-6 : Check the program version
You can check the versions of the main
PCB and the display PCB.
"n" is for the main PCB and "d" is
for the display PCB.
The soft cream level is set for the ingredients (vanilla) designated by the maker.
Depending on the ingredients, you will need to adjust it properly. Please follow the
instructions from our company when changing the level for the ingredients.

Check the temperature and the record
Functional description of the buttons
Press the "Select" button to check the different temperaturesettings
mentioned below. The item number and the temperature
will be displayed in turns.
2-1 : Temperature of the mixing tank
2-2 : Temperature of the mixing tank sensor
2-3 : Condenser suction temperature (neighboring temperature)
2-1 : Temperature of the mixing tank
The sensor located at the bottom of the mixing tank
to measure the temperature of ingredients may display
temperatures different from the actual ones if there is
no ingredient in the mixing tank or mixer.
2-2 : Temperature of the cylinder
The sensor located at the bottom front of the cylinder
may display temperatures different from those of
the ingredients or the ice cream.
2-3 : Ambient temperature of the condenser
The sensor located in front of the condenser can measure
the temperature of the ambient air entering the condenser
and the recommended installation conditions as well.
If 2-3 is too high, an error may occur.
This error is caused by poor environmental conditions
(clearance, cleaning, ventilation, etc.).
You should install the machine according to the manufacturer's recommendation.

Functional description of the buttons
Press the "Set" button for three seconds to enter the setting change
mode as follows.
Use the "▼" and "▲" to enter the password and use the "Set" button
to move to each item. When the display blinks, use "▼" and "▲" to
change the value and use the "Set" button to leave the item. Press
and hold the "Set" button for three seconds to leave the value change
mode.
Change the setting
3-1 : Adjust the soft cream level
This item is used to adjust the target current of the soft cream.
If the value is lower, the ice cream becomes softer. If the level is
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.
For your
information
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.

How to make soft ice cream
1. Open the top cover and pour ingredient
into the hopper tank.
※ Fill the ingredient bellow max level.
2. After pouring the mix, please insert the carburetor body
and carburetor tube into the hole in the hopper.
3. Close carburetor hole and apply impellers on the shaft
in the hopper.
4. Press AUTO button to start making soft ice cream.
● The smaller the carburetor 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 carburetor 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℃).

information
5. Please open the carburetor hole when
the ice cream level reaches at 100%.

How to adjust the carburetor
The carburetor has two components.
The one inserted into the hopper is“BODY”with a“TUBE”going
into the body.
The tube is open on both sides and cannot be inserted in the
wrong direction.
The carburetor hole is opened.
Match the projecting part on the upper“BODY”to the upper part
of the "TUBE" without a hole so that the hole in the lower part of the
“BODY”is plugged.
Conditions : When making ice cream for the first time
The carburetor is set to a bigger hole.
Match the projecting part on the upper“BODY”to the big hole
in the upper part of the "TUBE" without a hole so that the hole in the
lower part of the“BODY”matches the big hole.
This is to minimize overrun and increase the ingredient for the
continuous making of ice cream.
Conditions : For operation
The carburetor is set to a smaller hole.
Match the projecting part on the upper“BODY”to the smaller
hole in the upper part of the "TUBE" without a hole so that the hole
in the lower part of the“BODY”matches the smaller hole.
This is to increase overrun and decrease the ingredient when
demand for ice cream is low.
Conditions : For operation
The carburetor is set to a medium-size hole.
Match the projecting part on the upper“BODY”to the medium-size
hole in the upper part of the "TUBE" without a hole so that the hole in
the lower part of the“BODY”matches the smaller hole.
This is to set medium overrun and ingredient.
Conditions : For operation
Even if overrun is improved with a smaller hole, the amount of ice cream may vary depending
on the amount of ingredient in the hopper.
The smaller the amount of ingredient that the hopper has, the bigger the overrun will become,
and vice versa.
