3. Setup

3.1 Unpacking

1. Carefully remove all packaging materials, including tape and protective film.
2. Inspect the unit for any shipping damage. Report any damage to the carrier immediately.
3. Remove all internal packing materials and accessories.

3.2 Placement

• Place the refrigerator on a strong, level surface capable of supporting its weight when fully loaded.
• Ensure adequate clearance (at least 4 inches) around the back and sides of the unit for proper air circulation and heat dissipation.
• Avoid direct sunlight, heat sources, or areas with high humidity.
• The unit is designed for indoor use only.

3.3 Initial Cleaning

Before first use, clean the interior and exterior surfaces with a mild detergent and warm water. Rinse thoroughly and dry completely.

3.4 Power Connection

Connect the unit to a dedicated 115V/60Hz/1-ph electrical outlet. The unit comes with a cord and NEMA 5-15P plug. Do not use adapters or extension cords.

3.5 Initial Startup

After placement and power connection, allow the unit to sit for at least 2 hours before plugging it in. This allows refrigerants and oils to settle. Once plugged in, allow the unit to run empty for several hours to reach its operating temperature (32°F to 44.6°F) before loading products.

4. Operating Instructions

4.1 Temperature Control

The unit is equipped with an intelligent electronic controller (ETC1H) that manages the temperature. The factory preset temperature range is 32°F to 44.6°F (0°C to 7°C). Refer to the controller's specific instructions for adjusting temperature settings, if necessary. Avoid frequent and drastic temperature changes.

4.2 Loading Product

• Ensure products are pre-chilled before placing them into the refrigerator to maintain stable internal temperatures.
• Do not overload shelves. Allow space for air circulation around products.
• Avoid blocking the internal air vents.

4.3 Door Operation

The unit features a hinged locking glass door. Ensure the door is closed securely after each use to maintain internal temperature and energy efficiency. The lock provides added security for stored merchandise.

4.4 LED Lighting System

The interior LED lighting system is designed for optimal product display. It is typically controlled by the electronic controller or a dedicated switch. The low-profile, door-mounted, clip-in LED design ensures even illumination.

5. Maintenance

Regular maintenance ensures optimal performance and extends the lifespan of your refrigerator. Always disconnect power before performing any maintenance.

5.1 Regular Cleaning

• Interior: Clean the interior surfaces, shelves, and door gaskets regularly with a mild, non-abrasive detergent and warm water. Rinse thoroughly and dry completely to prevent mold and odors.
• Exterior: Wipe down the exterior surfaces with a soft cloth and mild cleaner. Avoid harsh chemicals that may damage the finish.
• Glass Door: Use a glass cleaner specifically designed for glass surfaces.

5.2 Condenser Cleaning

The condenser coil should be cleaned every 30-90 days, depending on the operating environment. A dirty condenser coil reduces cooling efficiency and increases energy consumption. Use a stiff brush or vacuum cleaner to remove dust and debris from the condenser fins. The newly designed condenser features reduced joints for improved long-term reliability.

5.3 Gasket Inspection

Regularly inspect the door gaskets for cracks, tears, or signs of wear. Damaged gaskets compromise sealing and lead to energy loss. Replace worn gaskets promptly.

5.4 Defrost Cycle

The intelligent electronic control system manages the automatic defrost cycle. Manual defrosting is generally not required. If excessive ice buildup occurs, contact qualified service personnel.

6. Troubleshooting

Before contacting service, review the following common issues and solutions:

• Unit Not Running:
  • Check if the power cord is securely plugged into a live outlet.
  • Verify the circuit breaker or fuse is not tripped.
  • Ensure the unit's power switch (if present) is in the 'ON' position.
• Insufficient Cooling:
  • Check if the temperature setting is appropriate.
  • Ensure the condenser coil is clean and free of obstructions.
  • Verify the door is closing properly and gaskets are sealing.
  • Avoid overloading the unit, which can restrict airflow.
  • Ensure ambient room temperature is within operating limits.
• Excessive Noise:
  • Check if the unit is level.
  • Ensure no objects are vibrating against the unit.
  • Fan motors may produce some operational noise; excessive or unusual noise may indicate a problem.
• LED Lights Not Working:
  • Check if the light switch (if applicable) is on.
  • Verify power supply to the unit.

If these steps do not resolve the issue, contact qualified service personnel.
