Warranty Information
No warranty period is specified in the manual.
Installation: Place on a rigid, level floor in a room with 10°C-43°C, away from direct sunlight or heat. Ensure adequate ventilation (30 cm top, 10 cm rear, 5 cm sides). Ground the refrigerator. Adjust leveling legs.
Before Use: Clean inside with a soft cloth. Connect to an exclusive wall power outlet. Allow approximately 4 hours (up to 24 hours in high ambient temperature) for sufficient cooling before storing food.
Optimal Food Storage: Allow space between food items. Cool food before refrigerating. Do not block cold air vents. Use wraps or sealed containers to prevent drying and odor transfer.
Operation: Temperature is controlled automatically. Adjust freezer and refrigerator compartment dials for desired cooling. Return to 'Normal' after using 'Coldest' to prevent freezing. Caution about food freezing in the refrigerator compartment near cold air vents.
Maintenance: Clean the refrigerator monthly. Unplug, remove food, wipe with a soft cloth and mild detergent if needed. Clean door gaskets. Inspect power plug and outlet.
Troubleshooting: Refer to the table for common issues like the refrigerator not cooling, freezing, smelling, or making noise.

| If a door is shut, other doors may open. | The air duct of two compartment is connected. When close one of the door, another door may be opened by the wind pressure. This is a normal phenomenon. | - |
| Does it have any abnormal sound? | The sounds like water flowing and boiling water are sound of the cooling liquid (refrigerant). A creaking sound comes from the storage compartment. It is the sound caused by friction of the parts due to temperature change. | - |
