5.2 Temperature Control (Super Cool & Super Freeze)
Use the electronic controls to set your desired temperature. For rapid cooling or freezing, utilize the special functions:
- Super Cool: This system can quickly lower the refrigerator temperature and maintain it at 2°C for 6 hours, allowing rapid cooling of stored food. This function ensures the preservation of flavor and nutrients in fresh foods and is excellent for quickly chilling beverages.
- Super Freeze: Super Freeze rapidly lowers the temperature and freezes food much faster than usual. This function preserves the natural flavor of foods, their original texture, and all beneficial vitamins and minerals.

6. Maintenance
6.1 Cleaning
Regularly clean the interior and exterior of your refrigerator. Unplug the appliance before cleaning. Use a soft cloth with a mild detergent and warm water. Avoid abrasive cleaners or solvents. Dry all surfaces thoroughly.
6.2 Defrosting
Due to the Total No Frost feature, manual defrosting is not required for this appliance. If ice buildup occurs, check if the door is sealing properly or if the temperature setting is too low.
6.3 Care
Periodically check the door seals for any damage or gaps. Clean the condenser coils at the back of the refrigerator annually to ensure efficient operation. When going on vacation, empty the refrigerator, unplug it, clean it, and leave the doors slightly ajar to prevent odors.
7. Troubleshooting
If you experience issues with your refrigerator, consult the following common troubleshooting tips before contacting service:
- Refrigerator not cooling: Check if the power cord is securely plugged in, the circuit breaker is not tripped, and the temperature control is set correctly. Ensure the door is closed properly.
- Unusual noises: Minor noises are normal during operation. If the noise is loud or unusual, check if the refrigerator is level and not touching a wall or other objects.
- Excessive frost/ice buildup: Although it has Total No Frost, check if the door is frequently opened or not sealing correctly.
- Water on the floor: Check the drain pan and ensure the drain hose is not blocked.
