4. Installation & Cautions

Please follow all instructions carefully.

General Cautions:

• After receiving the machine, let it stand for at least 5 hours before use.
• Ensure at least 50cm of free space on both sides of the machine for heat dissipation.
• Always fill both cylinders with mixture before operation. Operating with one or both cylinders empty is prohibited. Do not use water to test the machine.
• Allow the machine to remain stationary for 24 hours after transportation before operation.
• The power cord length should not exceed 10 meters.
• Always use both cylinders simultaneously.
• Use ice cream mixture prepared according to appropriate formulas.
• Ensure the machine operates with a stable voltage supply.

Placement:

1. Place the machine on a level, stable surface and lock the brakes.
2. Ensure good ventilation. Avoid direct sunlight and heat sources. Air outlets should be at least 1 meter away from walls or barriers. Other sides should have at least 0.5 meters clearance.
3. Avoid placing the machine in dusty environments.

Wiring:

1. Ensure the power socket is properly grounded.
2. The power supply should include a circuit breaker or other protective device against electric shock.

Power Code Requirements:

• The cross-sectional area of the power cord copper core must be:
• 18L and 20L machines: ≥ 2.5 mm²
• 36L and 48L machines: ≥ 4 mm²
• Using an under-sized power cord can lead to low voltage, overload, reduced machine performance, or damage.

Installation Steps:

1. Open the carton. A parts bag containing consumable parts (e.g., horn-shaped rubber rings, caps, O-rings, H-rings) will be found in the hopper. Keep spare parts for future use.
2. Check the nameplate on the right panel to confirm the correct model, voltage, frequency, and power.
3. Install the discharger securely. Tighten it to the machine using 4 bolts (2 long, 2 short), tightening diagonally. Ensure there is no gap between the discharger and the machine to prevent leaks during washing or operation. The sensor plate must be positioned on top of all valve stems.
4. Install the handles onto the valve stems one by one. Slowly push the steel pin through the discharger and the handles to secure them.

5. How to Make Ice Cream

1. Initial Wash:

1. Connect the machine to a 16A socket and switch on the power using the control panel switch.
2. Pour water into the hoppers to fill the cylinders.
3. Press the "CLEAN" mode. Repeat this process 2-3 times until the discharged water is clean.

2. Prepare Mixture:

You can use ready-made ice cream mixture or powder that requires mixing with water. Follow the instructions and formula on the powder packaging. Typically, mix 1kg of powder with 2.5-3kg of water. Stir thoroughly until completely dissolved and smooth, avoiding lumps. Let the mixture stand for 30 minutes. Proper preparation is crucial for the final texture and yield of the ice cream.

3. Make Ice Cream:

1. Ensure all water is completely drained from the cylinders.
2. Pour the prepared ice cream mixture into the hoppers.
3. Press the "CLEAN" button. The beater will start rotating to mix the mixture evenly. After 2 minutes, press "STOP", then press "WORK" to begin the freezing process.
4. Important Notice: Ensure the mixture level in each cylinder remains above the inlet of the discharger to prevent loud noise or damage to the machine.

6. Operation Guide

Display and Controls:

The LED display shows the progress of ice cream making. Typically, at 80% completion, the ice cream is ready for dispensing. At 100%, the machine automatically stops and returns to standby mode.

Control buttons include: "ON-OFF", "REFRIGERATION" (❄️), "CLEAN" (⚙️), "STOP", "HARD" (?), "SOFT" (☁️), "SETUP" (?).

Serving Ice Cream:

1. Place a cone or cup under the dispensing nozzle.
2. Press the handle down to dispense.
3. Slowly rotate the cone or cup in hand while dispensing.
4. Release the handle to stop dispensing.

Parameter Description:

Functional Operation:

1. Cleaning Function (⚙️):

In standby mode, press the "CLEAN" button. The stirring motor starts, and the "stirring" icon lights up. Press "CLEAN" again to stop the motor and extinguish the icon.

2. Automatic Function (❄️):

In standby mode, press the "REFRIGERATION" button. The "refrigeration" and "stirring" icons will light up, and animations will rotate. The stirring motor and balance solenoid valve start, with a 3-second delay for the main press. The balance solenoid valve stops. When the hardness reaches 99, the main press stops, the balance solenoid valve starts, and the stirring motor stops after a 5-second delay. The machine enters a waiting state. When the waiting time reaches the set cycle restart time, the process repeats. Pre-cooling of the material trough is controlled by temperature settings. If the trough temperature drops to or below the pre-cooling setting, pre-cooling stops. If it rises 2 degrees above the setting, pre-cooling resumes. Pressing "REFRIGERATION" again returns to standby, extinguishing the "refrigeration" and "stirring" icons.

3. Overnight Fresh-keeping Function:

Press the "Fresh-keeping" button. "Refrigeration" and "stirring" icons light up, and their animations flash. Pre-cooling of the cylinder and trough is temperature-controlled. If the cylinder temperature exceeds the set temperature by 2 degrees, the stirring motor, balance valve, and main press start (with a delay). The balance valve stops. When the cylinder temperature reaches the set point, the main press and stirring motor stop, and the balance valve operates with a 5-second delay. Pre-cooling of the material trough follows similar temperature controls. Once both trough and cylinder reach temperature, a 7-minute interval is required before cooling can resume. Pressing "Fresh-keeping" again returns to standby mode.

4. Parameter Setting (?):

In standby mode, long-press the "SETUP" button for 10 seconds to enter parameter setting. The display shows "P*" for parameter selection. Use the "SETUP" button to cycle through parameters and the "add/subtract" buttons to adjust values.

5. Zero Clearing (Cup Count):

In parameter setting mode, long-press both "add" and "subtract" buttons simultaneously for 5 seconds to reset the cup count and return to standby mode.

6. Alarm for Lack of Material:

During refrigeration or overnight fresh-keeping, if material runs low, the display will show "CL" and the machine will beep for 20 seconds. The machine will return to standby automatically when the set shutdown time for lack of material is reached.

Reference Speed Learning:

With empty cylinders, press the "CLEAN" button. Switch the A-B switch from A to B. Once the rotation speed stabilizes, the display will show "END", indicating successful learning. Switch the A-B switch back to A to complete the process.

Transfer Pump and Air Pump Operation:

• Transfer Pump: Starts when the machine is first powered on in refrigeration state or when the discharge switch is toggled. It stops after a specified time based on operation parameters.
• Air Pump: Operates when the mixing motor is running and switches on/off according to parameter timing. It stops when the mixing motor stops.
