4. Press AUTO button to start making soft 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℃).

Conversion function between
ice-cream mode and yogurt mode
How to set non-load
1) The default mode is the ice-cream mode.
2) The modes can be distinguished by checking LED's; lighting for the ice-cream mode,
and blinking for the yogurt mode.
① Pressing 'FREEZING CONTROL LEVEL' button for two seconds converts
to other mode (The buzzer sounds when conversion is complete).
② The yogurt mode is used for freezing stronger than the ice-cream mode.
Press the freezing adjusting switch for five seconds after supplying power in the MIX OUT
(no material) condition to enter into the program.
Perform non-load setting for each of the following cases:
1) New installation
2) Moving the system to other position, and reinstalling the system
3) After replacing parts relevant to producing ice-cream
(e.g., Desher motor, LUG POM and compressor)

Carburetor control
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 more the ingredients, the lower the overrun is.
information
For your
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 closed.
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 to enhanced over run
After the ice cream is created, it should be changed
to small, midium or bigger hole.
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
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.
For your
information
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.

2. If the machine is close to the wall and has no ventilation, it can stop. Please,
secure it at least 20~50cm from the wall.
3. Check whether the carburetor hole is blocked and if so clean out the hole.
4. Check whether the temperature in the ventilation hole (inhalation hole) is high.
Set the inhalation temperature of the condenser lower than 38
℃
.
Soft ice cream
is thin!
1. Check whether the carburetor is inserted.
2. In case there are no sales for more than 3 hours, the soft ice cream can be melted and made one more time
by using the recycling function (cover the carburetor hole during recycling).
The noise is
disturbing!
1. This product is an industrial machine and has some operation noise when compared to household appliances.
This product is designed to generate noise that is less than 70dB.
the customer satisfaction team in case abnormal noise is generated during machine operation.
2. A clicking sound can be generated during the initial operation.
This is the sound of plastic blade (dasher blade)that cleans the wall of the cylinder while making soft
ice cream.
Soft ice cream dose
not come out
enough!
1. Is the raw material need lamp blinking? In the case of MIX LOW, the ejection amount can become small.
In the case of MIX LOW, replenish the raw material.
2. The ejection amount can change by carburetor hole. The ejection amount can be large when a large
hole is used.
3. Did you set up ice cream level too high?
(If you increase the level, you may have lower amount of ice cream,
If you decrease the level, you may get more amount of ice cream)
Soft ice cream
comes out too
much!
1. Soft ice cream becomes thin and ejection amount may become large as time passes.
Remake soft ice cream by using the recycling function to solve the problem.
2. Ejection amount can change by carburetor hole.
The ejection amount can be small when a small hole is used.
3. Did you set up ice cream level too low?
(If you control a high level, you may have lower amount of ice cream,
If you control a low level, you may get more amount of ice cream)
If setting up the ice cream too high, no ice cream can be discharged
Overrun is not
working correctly.
1. Be sure to familiarize yourself with the user instruction.
2. Overrun will be improved by replacing the carburetor with one having smaller holes.
3. In case to operate the machine for a long time, If soft serve mix left 2/3 capacity of cylinder, it may cause
bad overrun, therefore to increase it, please draw about half amount of the soft serve mix and then
please make new ice cream. After that, you can produce soft ice cream with good overrun. But, if there
is less than 1/3 amount of ice cream in cylinder, it might cause over freezing and can’t draw any soft ice
cream.
When having bad
texture of soft ice
cream
1. When you use soft ice cream ingredient with high milk fat, it makes a bit of milk fat chunk inside ice
cream. If you have low sales volume, please adjust the carburetor hole at the smallest hole to prevent
from it.
Soft ice cream
has gone bad.
1. This product must be cleaned daily.
The remaining raw material must be wasted and new raw material must be used to make Soft ice cream.
The manufacturer is not responsible if this is not observed.
When having dark
color of ice cream
1. Did you insert the carburetors?
You can make good overrun when using small size carburetor hole.
2. You can make soft ice cream with good overrun by opening carburetor hole and by discharging (drawing)
ice cream several times.
