2. FCC Information
CAUTION: Modifications not expressly approved by the responsible party could void the user's authority to operate the equipment.
This device complies with Part 15 of the FCC Rules, subject to two conditions: 1) This product may cause harmful interference. 2) This product must accept any interference received, including interference that may cause undesired operation.
WARNING: Changes or modifications not expressly approved by the responsible party could void the user's authority to operate the product.
Note: This product has been tested and found to comply with the limits for a Class B digital device pursuant to Part 15 of the FCC Rules, designed to provide reasonable protection against harmful interference in a residential installation.
This product generates, uses, and can radiate radio frequency energy. If not installed and used per instructions, it may cause harmful interference to radio communications. No guarantee is made that interference will not occur. If interference occurs, users are encouraged to try correcting it by:
- Reorienting or relocating the receiving antenna.
- Increasing the distance between the product and receiver.
- Connecting the product to a different circuit than the receiver.

3. The Unpacking and Inspection of New Machines
- Cut and unpack straps and planks securing the carton. Remove the carton and foam board, and check the machine for damage. Note: The machine must not be tilted more than 45° during handling.
- Open the cylinder head and check if all accessories are complete against the packing list.
II. Using Environment
- Minimum ambient temperature: 5°C; Maximum ambient temperature: 35°C. Do not use in high moisture areas or where exposed to rain. Avoid places with sulfuric acid (like hot springs) or high salt content (like bays).
- Material temperature: at least 5°C, up to 40°C. Low temperature storage is recommended for improved ice cream production efficiency.
- Choose a well-ventilated location on a level and solid surface.
- Ensure at least 80 cm of space behind the ice cream machine and at least 30 cm of space on each side to allow cold air intake and hot air escape for the condensation cycle. Clean the condenser dust regularly.
Note: The machine may be shaken during transportation; it is best to let it stand for 4 hours after smoothing.
III. Electrical Connection
- Determine the required wire size for the connection circuit based on power requirements. All internal lines are pre-connected. Connect wires to the power cord at the rear and connect the ground wire. Note: All external wiring, plugs, and sockets must meet national standards.
- The incoming power supply voltage deviation should not be too high or too low. If it is, the indicator light (red) will flash and alarm (beep), and the cooling function will not start.
- Check the machine's nameplate on the rear panel to ensure the specified voltage matches the local power supply voltage.
- Entrust a qualified electrical construction unit to connect the ground wire to prevent electric shock in case of malfunction or leakage. (The grounding wire is typically yellow-green).
- Do not damage or process the power cord. Avoid bundling, stretching, bending, or twisting it.
- If the machine malfunctions, turn off the power. If a trip occurs, contact the store or service personnel.

IV. Sanitary and Parts Cleaning of Ice Cream Machine
- Use hygienic raw materials to avoid health risks.
- Do not return dispensed ice cream to the tank, as it may be harmful.
- Operators must wash hands and wear clean attire to ensure health.
- Clean parts before first use or after prolonged periods of non-use.
Use food detergent and a cleaning brush for dismantled parts, paying special attention to the O-ring groove. Note: Do not damage or lose parts. Avoid hot water or dishwashing detergent for resin parts to prevent deformation. Do not soak parts in detergent for over 30 minutes. Wash dirty parts carefully. The blade is very sharp; handle with care.
V. Assembly Method of Parts
- Agitator Assembly: Assemble the square shaft and bellows of the agitator by fitting the bellows into the square shaft (refer to Figure I). Rotate the square shaft after inserting the freezing cylinder to align the inner square hole.
- Stirrer Installation: Install the stirrer on the machine (refer to Figure J). After inserting the freezing cylinder, rotate the stirrer to align the square shaft and press it to ensure it is installed correctly.
- Discharge Valve Assembly: Assemble the discharge valve (refer to Figure K). Note: Ensure the seal ring is installed.
- Water Tank Installation: Install the water tank as shown (Figure L). Note: Ensure the control power switch is off during assembly.
Diagram Descriptions:
- Figure I: Illustrates the assembly of the agitator's square shaft and bellows.
- Figure J: Shows the installation of the stirrer within the freezing cylinder.
- Figure K: Depicts the assembly of the discharge valve.
- Figure L: Shows the installation of the water tank.
VI. Ice Cream Manufacturing Method
- Prepare ice cream slurry and pour it into the tanks at the top of the machine. Note: Slurry should not agglomerate.
- Turn on the power. The machine enters standby. Press "Wash" to run for 3-5 minutes. Then, press the handle to dispense 2-3 cups of slurry into the upper tank to prevent freezing at the discharge opening. Note: Prepare slurry according to the ice cream powder proportion.
- Press "Set" → "User setting" → "Hardness" to adjust ice cream hardness as needed. Note: Refer to machine "warm tips" for adjustment guidance.
- Press the "Auto" button to enter the cooling state. Press the "Fresh" button to cool the slurry in the feed chute.
- When the set hardness is reached, the machine automatically stops and rests. During rest (3-9 minutes), press "Set" → "User setting" → "Automatic restart time" to set the next refrigeration cycle. The time increases by one minute per press, resetting to 3 minutes after 9 minutes. Note: Set a short time in hot weather and a longer time in cold weather.
- Place an egg cone or cup at the outlet valve. Press the discharge handle to dispense ice cream, then push the handle back.
- If residual slurry or ice cream remains for a long time, press the "Fresh" button to keep it at a low temperature. For hygiene and energy saving, clean the machine daily, ensuring no residual ice cream remains.
- If cooling is complete and hardness is too high, or the freezing cylinder does not stir with no discharge, turn off the power, wait 30 seconds, press the "Thaw" button. After thawing, press "Cleaning". If material discharges normally, press "Start" again (for models with this feature).
VII. Ice Cream Machine Cleaning and Maintenance Methods
I. Cleaning of the Freezing Cylinder and Tank
To ensure consumer health and machine longevity, the freezing cylinder must be cleaned and disinfected after each use.
- Press the wash button to discharge all slurry from the tank, then press stop.
- Pour hot water and an appropriate amount of disinfectant into the tank, filling it to about 70%.
- Press the wash button again and stir for about 5 minutes before draining the cleaning solution.
- Rinse with hot water 2-3 times and stop.
- Use a cleaning brush for the chute discharge port and carefully clean the liquid level sensor with a clean cloth and brush. If cleaning is insufficient, the material shortage alarm may not function correctly. Remove the mixing blade, clean the rotating shaft and head with a clean cloth, and thoroughly clean the groove inside the rotating shaft with a brush. Wipe the tank with a clean cloth.
II. Washing and Unloading Parts
Turn off the power supply. Unscrew the four nuts of the discharge valve and remove the assembly. Detach the handle fixing pin, handle, valve rod, and sealing ring. The agitator is withdrawn from the freezing cylinder, and parts are disassembled for cleaning. Reinstall parts in reverse order.
III. Body Cleaning and Maintenance
Turn off the control switch power before cleaning the body. Wipe with a dry, soft cloth. For stubborn dirt, use a warm towel sprayed with food detergent, then wipe off residue. Clean the lower part of the machine and the base. Regarding the drain pipe, if it contains liquid from raw materials, it may indicate a defective motor shaft; contact the store or maintenance personnel. Note: Do not use polishing powder, gasoline, or hot water, as they can damage the surface. Do not use water directly to avoid leakage or accidents. Check the power cord monthly for damage.
IV. Cleaning and Maintenance of the Condenser
The condenser can accumulate dust, affecting heat dissipation and cooling efficiency. It should be cleaned every two months, preferably by a professional. Always turn off the power before cleaning and avoid damaging the condenser fins.
