Installation

Useful Instruction for Transport

To prevent oil in the hermetic compressor from flowing into the cooling circuit, always carry, store, and handle the machine in a vertical position, following packaging instructions.

If the machine was accidentally placed in a non-vertical position during transport, keep it upright for approximately 30 minutes before operating to allow oil to flow back into the compressor.

Unpacking

Remove wooden case board and plastic covering. Ensure the machine has not been damaged. Remove plastic film from stainless steel panels (if applicable).

Important: Keep packaging away from children as it can be dangerous. Dispose of packaging according to local regulations.

Positioning

• Do not install the machine in areas where water jets are used.
• Place the machine on a horizontal and sturdy surface.
• Install the machine in locations overseen by trained personnel.
• For good ventilation, maintain a distance of 20cm (7 inches) between the unit and walls or other objects. Increase this distance if obstacles are a heat source.
• When the dispenser is in place, press the brake on the wheels to keep it level (refer to FIG. 1).

Assembling

1. Remove the bottom pallet from the machine.
2. Place shelves onto the shelves.

Electrical Connection

Before inserting the plug, read the following precautions:

• Ensure the machine is properly connected to an efficient grounding system, compliant with current safety standards.
• Verify the voltage matches the "serial number" label on the chassis.
• The available current must be sufficient for the machine's maximum requirement.
• Use only approved multiple outlets compliant with current safety standards if necessary.

If in doubt, consult only specialized technicians. By law, the machine must always be grounded.

How to Use

Before use, clean the machine carefully as it comes into contact with food.

Functioning

1. Ensure the main switch is in the [1] position, then plug in the machine.
2. Before starting, ensure sliding doors are properly closed.
3. Turn the main switch to [1]; the condensing unit will start automatically.
4. For lighting, press the lighting button located on the thermostat.
5. If condensation forms on front curved glasses, turn the switch to [1] for defogging.

Working Temperature Adjustment

To reset the temperature, follow these steps:

CAUTION: It is not recommended to reset the temperature controller frequently.

Display and Controls: The display shows temperature. Buttons include SET, ▲ (up), ▼ (down).

1. Set Temperature:
   • Press SET button; the set temperature is displayed.
   • Press ▲ or ▼ button to modify and store the value. Press SET again to exit and display the cold room temperature.
   • If no button is pressed for 10 seconds, the cold room temperature will be displayed.
2. Illumination: Press the light button; it turns on. Press again to turn it off.
3. Manual Defrost: Press and hold the defrost button for 6 seconds to start or stop defrosting.
4. Display Evaporator Temperature: Press the button and hold for 6 seconds; the evaporator temperature is displayed. After 10 seconds, the cold room temperature is resumed.
5. Working LED: On during refrigeration; Off when cold room temperature is constant; Flashes during delay start.
6. Defrost LED: On during defrosting; Off when defrosting stops; Flashes during defrost delay display.
7. Parameter Setup:
   • Press and hold SET for 6 seconds to enter parameter setup mode (E1 flashes).
   • Press SET sequentially to select parameters: E1, E2, E3, E4, E5, E6, F1, F2, F3, F4.
   • Press ▲ or ▼ to display and modify parameter values.
   • If no button is pressed for 10 seconds, the cold room temperature is displayed.

Maintenance

Observe the Ambient Temperature

The machine is suitable for ambient temperatures between 16°C and 32°C.

Cleaning

Clean the interior of the machine frequently for health standards and quality of beverages or foods.

Caution: Do not clean the machine by water jet.

1. Before cleaning, remove the power plug.
2. Do not use abrasive powders that might impair interior parts.
3. Use neutral soap and warm water to wash interiors. Rinse carefully to remove soap residue.
4. To maintain high working performance, leave the machine turned on night and day to avoid deposit.

Caution: Do not use organic solvents (petrol, alcohol, etc.) as they may damage the machine and create explosive vapours. Do not use sharp-edged objects for cleaning.

The machine can be cleaned with a damp towel but should never come into direct contact with water. Ensure it is dried completely after cleaning.

Instructions for Disposal

When replacing an old machine, comply with the following:

Old machines contain valuable raw materials that can be reclaimed by recycling.

Render Old Machine Unusable:

1. Pull out the mains plug.
2. Cut off the mains cable and discard with the mains plug.

Caution: Refrigerants and gases in thermal insulation must be disposed of professionally. Ensure refrigeration tubing is not damaged prior to disposal. Please discard the machine according to local authority regulations.
