3. Precautions

1. Required Conditions of Environment

• Ambient temperature: 10 °C ~ 38 °C.
• Relative humidity: 55% ~ 85%.

2. Power Supply

• The socket must comply with national electrical safety standards of the user's country, and a grounding device must be installed. The grounding line's cross-sectional area must be not less than 1mm².
• The wires must meet local safety standards, including wiring methods and the required safety standards of the machine.
• Ensure the power supply circuit of the machine is equipped with short circuit and leakage protection devices.
• Three-phase power supply voltage should be 220V / 50Hz.
• The cross-sectional area of the power cord cannot be less than 1.5mm².
• For 380V or 220V Three-phase machines, observe if the stirring shaft rotates clockwise. If it rotates counterclockwise, replace any two of the firewires and reconnect them to the power supply, then perform a test.

3. Installation

• The machine should only be used indoors and placed on a horizontal, dry, solid ground. Any heat source above 70 °C is not allowed within a 500mm distance.
• Fig. 3 illustrates the required clearances between the machine, walls, and other items, showing dimensions for proper ventilation and access. The inlet and outlet of the condenser should be kept clear, with no foreign matter inhaled nearby.
• After placing the machine, engage the caster brake device to prevent shifting (depending on the model).
• For safety, the machine must be operated or supervised by well-trained personnel with adequate electrical and mechanical safety knowledge, who fully understand the machine's operating requirements.
• Operators must fully understand food hygiene requirements and hold a health certificate issued by the local health management department, in line with health laws.
• Operation should adhere to hygienic requirements, including the use of qualified auxiliary tools, containers, and hygiene items like hoods, masks, and gloves.

4. Safety Rules

Notes

• The machine may be subject to shock during transport; it is advisable to use it 24 hours later.
• Keep the machine away from sunlight and high-temperature radiation heat sources.

Precautions

• For safety, the machine must be operated or supervised by well-trained personnel who fully understand its special operating requirements.
• If the machine fails or the power cord is damaged, it must be handled by the manufacturer, authorized maintenance department, or a professional qualified refrigeration serviceman.
• When the machine is not used for a long time, disconnect the power, clean parts in contact with raw material, and keep them dry.
• Keep the machine clean and sanitary; promptly clean up ice cream mixture to avoid corrosion.
• Do not rinse any part of the machine with a faucet.

Dangers

• Do not touch live plugs or switches with exposed skin, in wet environments, or with wet gloves or clothes.
• Do not operate a machine that is not properly grounded.
• Do not perform any maintenance work before disconnecting the power supply.
• Do not open the side panels before disconnecting the power supply.

Transport and Storage

• Do not tilt the machine more than 45°C while moving it, and avoid violent vibration.
• Store away from sunshine and rain. The ambient temperature should be between -15 °C ~ 55 °C, with relative humidity less than 85%.

Maintenance Area

• Access to the maintenance area requires removing the side panel (or other board).
• Maintenance should only be performed by well-trained qualified personnel.

4. The Ice Cream Ingredients

Buy ingredients directly from ice cream powder suppliers or prepare them yourself.

5. Cleaning Procedure

1. Preliminary Clean-out

1. Open the lid, twist down the screw cap on the stirring shaft, and remove the stirring shaft from the cooling cylinder.
2. Wash the cylinder, stirring shaft, and outlet with lukewarm water using a mild, non-foaming detergent that meets hygienic requirements. Scrub each part with cleaning brushes. Finally, reassemble the parts.

Note: Do not use hot water above 40 °C to wash plastic parts, as it may damage the original seals inside the machine.

2. Cleaning After Ice Cream Dispensed

After your schedule, remove any remaining ice cream in the cylinder. Open the lid, rinse the cylinder with the machine's faucet, then close the lid. Turn on the machine, press the “Cleaning” button, and let the beater run for about 3 minutes. Drain all water from the cylinder. This entire cleaning process can be repeated several times.

6. Ice Cream Processing

1. Processing

Wash, sterilize, and thoroughly rinse the machine before use.

Pour the desired volume of ice cream mixture into the cylinder. Follow the minimum and maximum volume limits allowed by the machine; for the EMB20, the minimum is 4L.

Before filling with mix, ensure the front door and ice cream gate are properly closed.

Push the "Auto” button. The machine will start processing by beating and cooling the ice cream mix. The processing time is shown on the display panel by a time indicator and can be preset. When the freezing time reaches the preset value, the machine will stop freezing automatically, indicating the ice cream is ready to be dispensed.

To dispense ice cream, hold a pan under the ice cream gate, open the gate, and push the "Dispense" button. Place the dispensed ice cream into a blast freezer.

If you wish to add ingredients like peanuts during processing, push the "P" button to stop the machine first, then push the "Auto" button to continue.

Note: The processing time is typically about 15-20 minutes for the EMB20 model. This may vary based on recipes and ambient temperature, and can be adjusted accordingly.

2. Setting of Processing Time

Push the "Set" button twice until the numbers on the control panel flicker. Then, press the “-” or “+” buttons to set the cooling time and press the “Enter” button to save the setting.

Note: If continuing to make ice cream, the second dispensing time may be shorter.

7. Maintenance

1. Forbid metal foreign bodies (e.g., metal spoons) from entering the machine, as they can damage the motor.
2. Replace the sealing ring every year.
3. Adjustment and replacement of scraper: Under normal circumstances, fine-tune the scraper annually to ensure it contacts the cylinder wall.
4. Gearbox maintenance: For high-load machines, it is recommended to add lubricating oil regularly to prevent dry grinding.
5. For air-cooled machines, clean the condenser's air network and fan every 3-6 months to ensure efficiency.
   1. Disconnect the main power supply.
   2. Use a screwdriver to remove the fixing screws from the condenser outlet plate and then remove the plate.
   3. Remove dust and fluff from the condenser with a brush.

Note: a) Never use a screwdriver or other metal object to clean parts between the fins. b) If dust is difficult to clean, contact refrigeration professionals.

(You can deal with it flexibly as you see fit.)

Cautions:

Any operation requiring the opening of the machine must be carried out with the machine stopped and disconnected from the main power supply. Repairs of electrical and freezing plants must be performed by skilled engineers.

8. Warranty Description

1. When using the machine, follow the specified methods and precautions.
2. If troubles occur during processing, refer to the troubleshooting guide. If problems persist, contact the dealer or the manufacturer.
3. Warranty is for one year from the machine's delivery date (indicated on the nameplate). If the machine malfunctions due to quality problems, dealers or the manufacturer will provide free maintenance within the warranty period.

Note: Free maintenance will not be provided if the machine is not operated correctly according to the instructions in this manual. For example, if hard objects fall into the cylinder during ice cream processing, causing damage to the cylinder or blade, free maintenance will not be offered.

9. Troubleshooting Guide

The "*" indicates that it must be repaired by the manufacturer, its authorized after-sales service department, or a professional qualified refrigeration service personnel.

Note: The company reserves the right to make improvements to all models, subject to change without notice.
