The Ice Cream Dispenser has been fully inspected and tested at the factory prior to shipping.
If you detect damage to the wooden package or apparent distortion of the shape of the system
after unpacking the product, immediately inform your distributor or manufacturer.
Find the serial number marked on the packing and the machine before starting installation.
Inform us of the serial number if you have any inquiry. Request the dealer or service provider
for assistance when the machine is to be moved.
1. Remove the wooden packing, taking care not to damage the exterior of the Ice Cream
Dispenser.
2. Remove the wooden packaging and the protective tapes and make sure that all parts of
the system are complete.
※ When tilting or moving the machine, take care not to overturn the machine.
1. Avoid sloping or irregular surface.
- Installation on a sloping or an irregular surface may result in machine overturning, malfunction,
or failure.
2. Avoid direct sunlight, rain, snow, and wind.
- Otherwise, re or electric shock may occur due to the ice cream or rain water.
3. Avoid the direct inuence of sea wind and hazardous gases.
- Ice cream buyers may complain or le a claim.

- Consult with the engineers of the company for the details of installation of the system to ensure optimal
performance of the system (change of the installation site of the system also requires consultation with
the engineer of the company).
- Do not install the system on a place with adverse conditions such as uneven oor, place exposed to direct
light, or place with too much dusts or direct splashing of water.
● Electrical connection
1. Connect the main power for single-phase
power distribution box.
Install an earth leakage breaker (with capacity of
30A or higher) in the distribution box.
◆
Earth shall be provided for the safe operation of the system.
◆
Maintain space of 50cm or more each between
the walls and the right and rear sides, 20cm or more
between the left of the system.
◆ Precisely seat the rubber feet at the bottom to
prevent slipping
2. Remove the screws of the left side cover
and remove the cover of the inside control
box by the same method.
3. Plug in the power cord and measure voltage at the ends of
two power cords (L, N) of termnal block.
4. Measure the phase voltages.
They should match the voltage displayed in
'1-3'. If not, then using a straight headed
driver, adjust the PCB variable resistancel
ocated in the control box at the bottom front
of the product as shown in the gure on the right.
Measurement must be taken by a qualied electrician and adjust voltage to values displayed in '1-3'.
Otherwise, icecream will be too waterly or too thick.

●
Check the followings after connecting the feed and discharge water lines:
1. Feed water pressure should be between 1~3kgf/㎠.
▶If the water pressure is too high, water may leak at connections.
2. If the temperature can go down below 10℃, provide a means to prevent freezing.
▶Freezing can cause water leakage or failure of the system.
3. There should be a tap water valve when you connect the system to tap water.
Close the tap water valve if there is water leak due to a defect of the tap on top of the product.
1. Coil teon tape 5~10 times around the thread of
water supply connector.
2. Fir rubber packing in the corrugated tube nut
of the feed water line and join it to the water
inlet of the product.
Tighten the nut rmly with a tool.
3. Pay special attention to protecting Section “A”
from damage when assembling the tools.
● Water Supply Connection
The raw water supply valve may vary depending on the installation environment of the system.
Measurement must be taken by a qualied electrician and adjust voltage to values displayed in '1-3'.
Otherwise, icecream will be too waterly or too thick.

For long-term storage
1. Drain raw ice cream liquid, clean the machine, and assemble the dasher cover and dasher
assay while the body is still wet from cleaning.
2. Lock the water supply valve. The power supply must be connected at this point, so check if it is.
3. Disconnect the water supply valve from the side of
the machine to drain any remaining water in
the line. (Figure 1)
4. Unscrew the quick valve cover from the lower part
of the left panel and have a basket ready at the
outlet hose.
5. Turn and open the quick valve inside of the valve
cover counter-clockwise.
This will allow the water to flow from the outlet hose.
(Figure 2)
6. Press the "AUTO" button and keep the machine
running for 5~10 minutes.
7. Press the "STOP" button on the front to stop the machine.
8. After water is completely drained, lock the water valve (Figure 1)
and quick valve (Figure 2) and close the cover.
(About 1.3~1.5 liters of water will be drained.)
9. To reuse the machine, lock the quick valve again (Figure 2) and reconnect the water
supply line (Figure 2)
(Up to 10 minutes until the high-pressure switch is activated and
the machine stops.)
(The basket is for collecting the water that may spill
on the ground.)
(Refer to the user instruction for the cleaning method.)
Waring
●The machine will be out of order if water gets frozen due to sub-zero temperature in winter.
Be sure to drain water before storing the machine.
●The manufacturer will not be responsible for the freezing and bursting of the machine without
draining water. Be sure to keep the following precautions to avoid charging of excessive
repair cost:
●Be sure to check the following when connecting the water supply line!
1. The pipe must have a diameter bigger than Φ12.7mm.
2. Check if the pressure is between 0.3 and 0.5 Mpa on the water pressure gauge after
connecting the line. (The water pressure gauge is on the back of the machine.)
3. If pressure is lower than 0.3 Mpa when operating the machine, control the flow of
the main valve to ensure stable operation.
4. The high-pressure cut-out switch (HPS) of the machine will be activated to stop and
protect the machine unless pressure is strong enough.
Remember to maintain the proper water pressure.

Check prior to use
【Make sure to check them prior to use 】
Install it independently in an earth leakage circuit breaker with more than 20A and
provide an external grounding.
(Ask a qualied electrical technician for the installation.)
The power cable should be connected before the product can be operated normally.
If you intend to leave it unused for a long time, wash it and turn off the water supply
valve and turn off the earth leakage circuit breaker.
The air suction and discharge should be facilitated so that the cooling
performance can be optimized.
For better taste of soft ice cream, do not miss the lter cleaning time.
It is recommended to clean the cylinder, the mixing tank,the impeller, the dasher,
the caburator, the cup sensor, the piston every day.
Clean the condenser at least once a month or more often.
※This does not apply to 'ISI-300TW' (water cooled model).
This product is for 1PH / 220V, 60Hz
● Do not block the air vent.
● Periodic lter cleaning
● Clean the condenser once a month.
