12. Installation and debugging

1) Installation

• Cut off and dismantle the packing belt of the fastened carton. Get rid of the carton and take down the packaging bag to check whether the appearance of the machine is damaged and whether the accessories are complete with reference to the list.
• The machine should be placed evenly and stably, and after that, please lock the brake of the front wheel tightly.
• Install the handle to the liquid outlet valve according to the product structure diagram. Then install the assembled liquid outlet valve on the machine and tighten it with the fixing nuts.
• Working conditions: Ambient temperature: 5–40℃; material feeding temperature: 2–35℃ (Note: The material feeding temperature will directly influence the refrigerating capacity and outputs.)
• Supply voltage: 200–400 V (The deviation of rated supply voltage cannot be too high or too low. If it is too high or too low, the machine will alarm (buzzing), and the machine cannot start.)
• Supply frequency: 50 ±1 Hz
• Placing conditions: The machine should be placed in a cool and ventilated location and avoid heat sources and direct sunshine. The distance between the air exhausting side of the machine and the wall or other similar obstacles should be over 1 m, and the rest of the sides of the machine should be over 0.3 m away from the wall or other similar obstacles, so that the cool air can flow into the machine and exhaust the hot gas to ensure the condensation cycle of the machine.
• The machine should not be located in a dusty place. Please keep the place clean and tidy, and regularly clear away the dust on the condenser.
• Requirements for power supply wiring: Please ensure the power supply circuit of the machine is equipped with short-circuit protection and earth leakage protection devices.
• Please ensure the power line is not less than 2.5 mm² and is a copper core wire (excluding exceptionally high-power machines, whose power line should not be less than 4.0 mm² and should be a copper core wire), and the power line should not be too long. When the power line is too small or too long, its load will become too large and cause a voltage drop, thus affecting the service life of the machine’s components.

In other words, when you start the left jam pump, the right one will automatically switch off, and vice versa. When you do not need the jams, please keep in mind to switch off the “Jams” key before making ice cream.

6. Ice cream making method

• At present, in China, ice cream is usually made by mixing the ice cream materials with water. Please mix them in strict accordance with the ratio printed on the ice cream bag (generally 1 kilogram of ice cream material should be mixed with 2.5–3 kilograms of purified water).
• Place the mixed ice cream pulp down for 15 minutes and then evenly pour it into the two material cylinders on the top of the machine. It is required that the pulp does not cake, so that it can smoothly flow into the refrigerating cylinder through the feeding hole of the puffing tube.
• Pull down the left and right handles to let the two discharge holes flow out 2–3 cups of ice cream pulp naturally. Then pour it into the top material cylinders to prevent water from freezing at the discharge mouth, as it will influence the making of ice cream.
• Switch on the power supply. As the machine enters the standby state, press the “Cleaning” key and let the machine run for about 3–5 minutes. After that, press the “Stop” key to stop the machine.
• Press the “Auto” key. As the machine enters the refrigeration and moulding state, press the “Soft or Hard” key to choose the hardness of the ice cream as you want (note: during the prior cleaning state, you must closely observe the current hardness value displayed. If the current value is displayed as 3.5, then the hardness of the ice cream should be set between 4.5 and 5.5. If it is displayed as 4.0, then the hardness should be set between 5.0 and 5.5.
• When the actual measured hardness of the ice cream reaches the set value, the machine will automatically stop operation and enter the standby state. At this time, you can press the “Time” key to set the time as required for the cycle of automatic refrigerating. The automatic refrigerating cycle is set at 3–9 minutes. Each time you press the key, 1 minute is increased. Until it reaches 9 minutes, if you press the key again, the machine will return to the 3-minute state (note: when it is hot, it is better to set the stop time shorter, and vice versa).
• Take one ice cream cone or cup and place it at the valve outlet. As you pull down the material discharge handle, the ice cream will be extruded. After a while, pull back the handle, and it is OK.

7. Maintenance and repair

To guarantee the health of ice cream consumers, improve the service life of the machine components, and avoid unnecessary troubles, you must clean the refrigerating cylinder once a day.

• The cleaning of the refrigerating cylinder
• Press the “Cleaning” key to discharge all the pulp inside the cylinder. Press the “Stop” key to stop the machine.
• Add an appropriate amount of disinfectant to warm water. Then pour the mixture into the two material cylinders respectively, each with basically the same amount of solution.
• Press the “Cleaning” key again and let the machine stir for about 5 minutes. Then, discharge the cleaning solution.
• Clean the machine 2–3 times with clear water and then stop the machine.
• Switch off the power supply. Dismantle the components and clean them.
• Screw off the four nuts used to fix the liquid outlet valves and dismantle the valve components.
• Pull out the handle, steady pins, handle, piston, and valve seal in turn from the liquid outlet valve components.
• Pull out the stirring shaft from the refrigerating cylinder.
• Clean all the dismantled components and replace the damaged ones in time if there are any.
• After cleaning, apply Vaseline to the components that need lubrication according to the following diagram.
• Then assemble the components in the reverse order of dismantlement.

2) Body cleaning

Since consumers require a beautiful appearance and a clean and sanitary machine, please keep the appearance clean at all times. You can use a warm towel to scrub the body to remove dirt and spots, but avoid washing it directly with water in case the appliance breaks down.

3) Condenser cleaning

After the machine works for a period of time, the condenser will be covered with dust, thus affecting heat dissipation and making the refrigerating effect worse (which is embodied by the output of ice cream dropping at the same time or being hard to take shape). Please have it cleaned once every three months (if the working environment is poor, please clean it once every month) by professional workers. Before cleaning the condenser, please switch off the power supply and take care not to damage the condenser fins.

4) Adjustment of the belt

After the machine works for a period of time, the driving belt of the stirring system may be stretched longer, so timely adjustment of the belt should be made by professionals. Before adjustment, you must cut off the power supply. Then dismantle the enclosure plates to adjust the belt tension nuts and ensure appropriate tightness. If you still feel the belt is too loose after adjustment, please replace it with the same type of belt.

Notes: After a long time of use, it is normal for the driving belt to wear down, which is not included in the after-sales service of our products. When the driving belt becomes longer, the following phenomena may occur: the machine does not work, hardness changes, big noise, glue smell, etc. Please have it adjusted in time by yourself or by professionals. If necessary, please replace it. The time interval for adjustment and replacement depends on the machine’s utilisation rate.
