2. Setup and Installation

2.1 Unpacking

Carefully remove the unit from its packaging. Inspect for any shipping damage. Retain packaging materials for future transport if necessary.

2.2 Placement

• Place the display case on a stable, level surface capable of supporting its weight (approximately 52.5 kg when empty).
• Ensure adequate ventilation around the unit, especially at the rear where the compressor is located. Avoid placing it directly against a wall or in an enclosed space without airflow.
• Keep the unit away from direct sunlight, heat sources (ovens, stoves), and areas with high humidity.
• Allow at least 10 cm of space around the sides and rear for proper air circulation.

2.3 Initial Cleaning

Before first use, clean all interior and exterior surfaces with a mild detergent and warm water. Rinse thoroughly and dry completely. Do not use abrasive cleaners or sharp objects.

2.4 Power Connection

• Ensure the power supply matches the unit's requirements: 1N/PE 220-240 V / 50 Hz.
• Plug the unit into a grounded electrical outlet. Do not use extension cords or adapters.
• After plugging in, allow the unit to stand for at least 2-4 hours before turning it on. This allows the refrigerant to settle.

3.2 Temperature Control

The unit features a digital thermostat for electronic temperature regulation. The factory-set temperature range is 2°C to 8°C.

• Viewing Current Temperature: The digital display continuously shows the current internal temperature.
• Setting Temperature:
  1. Press the "SET" button once. The display will show the current set point.
  2. Use the "Up" (▲) or "Down" (▼) arrow buttons to adjust the desired temperature.
  3. Press "SET" again to confirm the new setting, or wait a few seconds for the display to revert to the current temperature, saving the change automatically.

3.3 Loading GN Containers

The display case is designed to hold 10 GN 1/4 containers. Ensure containers are properly seated for efficient cooling. Avoid overfilling containers, as this can impede air circulation and cooling performance.

4. Maintenance

Regular maintenance ensures optimal performance and longevity of your refrigerated display case.

4.1 Daily Cleaning

• Disconnect the unit from the power supply before cleaning.
• Remove all GN containers and food items.
• Clean the interior and exterior surfaces with a soft cloth, mild detergent, and warm water.
• Wipe down the glass cover and side panels.
• Rinse thoroughly with clean water and dry completely to prevent water spots and bacterial growth.
• Do not use abrasive cleaners, steel wool, or harsh chemicals, as these can damage the stainless steel and glass surfaces.

4.2 Defrosting

This unit features manual defrosting. Frost buildup can reduce cooling efficiency.

• When frost accumulation becomes noticeable (e.g., 5mm thick), disconnect the unit from power.
• Remove all food items and GN containers.
• Allow the frost to melt naturally. You can place towels to absorb water. Do not use sharp objects or heating devices to speed up defrosting, as this can damage the evaporator.
• Once defrosted, clean and dry the interior thoroughly before reconnecting power and resuming operation.

4.3 Condenser Cleaning (Periodic)

The condenser coils, located at the rear or bottom of the unit, should be cleaned periodically (e.g., every 3-6 months) to ensure efficient operation. Dust and debris can accumulate, reducing cooling capacity and increasing energy consumption.

• Disconnect power.
• Carefully access the condenser area (refer to service manual if unsure).
• Use a soft brush or vacuum cleaner to remove dust and lint from the condenser coils.
• Ensure all vents are clear.
