4. Setup

1. Unpacking: Carefully remove the display cabinet from its packaging. Inspect for any shipping damage.
2. Placement: Place the unit on a stable, level countertop. Ensure there is adequate space (at least 4 inches) around the sides and rear for proper ventilation. Avoid direct sunlight or proximity to heat sources.
3. Power Connection: Connect the power cord to a dedicated 220V, grounded electrical outlet. Do not use extension cords.
4. Initial Cleaning: Before first use, clean the interior and exterior surfaces with a mild detergent and a soft cloth. Rinse and dry thoroughly.
5. Initial Operation: After cleaning, allow the unit to stand upright for at least 2 hours before plugging it in to allow refrigerants to settle. Plug in the unit and allow it to run empty for 2-4 hours to reach the desired temperature before loading products.

5. Operating Instructions

1. Power On/Off: The unit is powered on by plugging it into the electrical outlet. Use the power switch on the control panel (refer to Figure 3.3 or 3.7) to turn the refrigeration system on or off.
2. Temperature Adjustment: The temperature can be adjusted via the digital control screen. The recommended operating temperature range is 35.6℉-46.4℉ (2℃-8℃). Consult the control panel's specific instructions for setting the desired temperature.
3. Loading Products: Use the rear sliding door (refer to Figure 3.6) to place or retrieve items. This minimizes temperature fluctuations in the display area. Arrange products to allow for proper air circulation.
4. Demisting Function: The demist function is typically activated automatically or can be manually controlled via the control panel. This feature uses an electric heating wire to keep the front glass clear of condensation.
5. LED Light Operation: The internal LED yellow light can be switched on or off using a dedicated switch on the control panel to illuminate the displayed items.

6. Maintenance

• Daily Cleaning: Wipe down the interior and exterior surfaces, including glass panels, with a soft cloth and a mild, non-abrasive cleaner. Ensure no cleaning solution enters the electrical components.
• Shelf Cleaning: Remove shelves and clean them separately with warm, soapy water. Rinse and dry completely before returning them to the cabinet.
• Condenser Coil Cleaning: Periodically clean the condenser coils (located at the rear or bottom of the unit) to ensure efficient operation. Use a brush or vacuum cleaner to remove dust and debris. This should be done by a qualified technician if access is difficult.
• Door Seal Inspection: Regularly check the door seals for any signs of wear or damage. Damaged seals can lead to inefficient cooling and increased energy consumption.
• Frost-Free System: The unit features a frost-free system, minimizing the need for manual defrosting. However, ensure proper air circulation inside to prevent ice buildup.
