How to Use the MG121

Before You Start

Proper preparation ensures smooth operation and extends the life of your machine. Begin by placing the MG121 on a stable, level surface with at least 10 cm of ventilation space around it. Use a grounded outlet that matches the rated voltage – the outlet capacity must be ≥15A.
Next, add sugar by opening the 4 container lids and using the dedicated funnel. Add sugar from left to right: white, red, yellow, blue. Maximum capacity is 300g per container. Install the transparent cover by aligning it with the metal positioning heads and pressing down until it clicks into place. Finally, check the water tray – it must be clean, dry, and properly placed, as the machine will not start without it.

Important: Use only dedicated granulated cotton candy sugar. Do not use powdered sugar, rock sugar, or brown sugar.Standard Startup

Power on the machine – the bottom light strip will glow yellow in a breathing pattern, indicating standby mode. Press and hold the Power/Make button for 5 seconds until the light strip turns green. Wait for the light panel to stabilize to a single solid color – startup is now complete.
The machine automatically enters standby mode after 3 minutes of no operation. Press any button to wake it up.

Making Cotton Candy – Step by Step

Start by inserting the paper stick into the robotic arm. Press the color selection button to choose from 64 combinations – or skip this step for random colors. Short-press the Make button to begin. The machine completes the cotton candy in approximately 50 seconds, then the robotic arm moves to the pick-up position for you to remove your cotton candy.

After each cycle, the heater head spins at high speed for 10 seconds to clear residual sugar – the machine is then ready for the next one.

Adjusting Sugar Output

If you notice excessive flying strands or the size is too small, turn the knob to the right (blue) by 1–2 gears. If there is too much fluff, no output, or the size is too large, turn the knob to the left (red) by 1–2 gears. For size adjustment, press “+” to increase size or “-” to restore default. Make 1–2 cotton candies after each adjustment and observe the effect.

Important Safety Tips

Do not open the transparent cover while the machine is running, and never add sugar or perform maintenance during operation. Replace the water tray promptly – removing it automatically stops the machine. Do not place any objects on top of the device.

Pro Tips for Outdoor & Night Market Operation

Practical tips beyond the standard manual – for real-world vending.

High-Temperature Outdoor Operation

When operating in hot weather above 30°C (86°F), place the machine under a canopy or umbrella to avoid direct sunlight, which can affect heating stability. Allow slightly longer cooling time between batches, and monitor the water tray more frequently – replace it as needed. Keep spare sugar in a cool, dry container, as heat and humidity cause clumping that can block the feeding system. Ensure at least 15 cm of ventilation space around the machine in outdoor settings for proper heat dissipation.

Extended Night Market Operation

Prepare 2–3 spare water trays for quick swaps during busy periods. During peak hours, pre-make a small batch and display them to reduce customer wait times. Night markets often have unstable power, so use a voltage stabilizer (≥15A) to protect your machine. The MG121’s LED ring light naturally attracts attention – position the machine so the light is visible from a distance. Use downtime (10–15 minute lulls) to wipe down the machine and clear sugar debris.

General Vending Tips

Display 2–3 finished cotton candies on the counter – visual appeal drives impulse buys. Use the 64 color combinations to offer variety and charge a premium for special mixes. Know your peak hours: weekends and evenings are prime time, so stock extra sugar and paper sticks before busy periods.

Cleaning and Maintenance

Warning: Always power off the machine, unplug it, and allow the heater head to cool completely before cleaning.

Daily Cleaning (After Each Use)

Power off and unplug the machine, then let the heater head cool. Remove the transparent cover and wipe it with a damp cloth. Take out the water tray, wash it with warm water and neutral detergent, dry it, and put it back in place. Finally, wipe the machine body with a damp cloth and clean up any sugar strands or debris.

Regular Maintenance

The heater head should be cleaned after 200–300 cotton candies – contact SUNZEE support for disassembly instructions and never use sharp tools to scrape the surface. Clean the sugar feeding tube and module once a month using a soft brush, compressed air, or hot water for blockages, and wipe dry before reassembly. When replacing sugar, empty remaining sugar from the containers – do not wash with water – and remove all clumps before adding new sugar.

Long-Term Storage

For long-term storage, empty all sugar containers and clean thoroughly. Store the machine in a dry, ventilated, cool place and cover it with a dust cover. Power on and run the machine once every 3 months to prevent moisture damage.
