3.4 Initial Power-On
After placement and assembly, plug the refrigerator into a dedicated power outlet. Allow the unit to stand upright for at least 2-4 hours before plugging it in to allow the refrigerant to settle. This ensures optimal cooling performance.

5. Maintenance
5.1 Manual Defrost
This refrigerator features a manual defrost system. When frost accumulates to a thickness of about 1/4 inch (6mm), the freezer compartment should be defrosted. To defrost, unplug the unit, remove all contents, and allow the frost to melt naturally. Place a towel or shallow pan to catch melted water. Do not use sharp objects to remove ice.
5.2 Cleaning
Clean the interior and exterior of the refrigerator regularly with a mild detergent and warm water. Wipe dry with a soft cloth. Avoid abrasive cleaners or solvents. Clean the door gasket to ensure a tight seal.
