4. Installation and Setup

4.1 Unpacking

1. Carefully remove all packaging materials. Inspect the unit for any shipping damage. Report any damage immediately to the carrier and supplier.
2. Remove all protective films and tapes from the surfaces.

4.2 Placement

1. Place the display refrigerator on a sturdy, level countertop or surface capable of supporting its weight when fully loaded.
2. Ensure there is adequate air circulation around the unit, especially at the rear and sides where the compressor is located. Maintain at least 4 inches (10 cm) of clearance.
3. Avoid direct sunlight, heat sources, or areas with high humidity, as these can affect cooling efficiency.

4.3 Electrical Connection

1. Verify that the power supply matches the voltage requirements specified on the product label (220V).
2. Plug the unit into a dedicated, grounded electrical outlet. Do not use multi-outlet adapters or extension cords.

4.4 Initial Cleaning

1. Before first use, clean the interior and exterior surfaces with a mild detergent and a soft cloth. Rinse thoroughly and dry completely.
2. Ensure all glass shelves are clean and properly installed.

4.5 Initial Operation

1. After placement and cleaning, allow the unit to stand upright for at least 2 hours before plugging it in. This allows the refrigerant to settle.
2. Plug in the unit. The compressor will start, and the internal temperature will begin to drop.
3. Allow the unit to run empty for 2-4 hours to reach the desired operating temperature before loading products.

5. Operation

5.1 Powering On/Off

The main power switch is located at the rear of the unit, near the control panel. Press the switch to turn the unit on or off.

5.2 Temperature Control

The unit features a digital temperature control and display. The recommended operating temperature range is 39.2℉-50℉ (4℃-10℃).

1. Viewing Current Temperature: The digital display shows the current internal temperature.
2. Adjusting Temperature: Refer to the specific instructions on the digital controller for setting the desired temperature. Typically, there are 'Set' and arrow buttons to adjust the temperature up or down.

5.3 LED Lighting

The internal yellow LED lighting enhances product visibility. The light switch is located on the control panel at the rear of the unit. Toggle the switch to turn the LED lights on or off.

5.4 Loading and Display

• Arrange products evenly on the shelves. Do not overload shelves beyond their weight capacity.
• Ensure products do not block the internal air circulation vents, as this can impair cooling performance.
• Close the back sliding doors completely after accessing products to maintain internal temperature.

5.5 Automatic Defrost

This unit is equipped with an automatic defrost feature. During defrost cycles, the evaporator coil is heated to melt any accumulated ice. The melted water drains into an evaporation pan and is evaporated. This process is automatic and requires no user intervention.

5.6 Demisting Function

An electric heater strip is integrated into the front glass to prevent condensation and demist the display, ensuring clear visibility of your products.

6. Maintenance

Regular maintenance ensures the longevity and efficient operation of your display refrigerator.
