3. Setup
3.1 Unpacking
- Carefully remove all packaging materials.
- Inspect the refrigerator for any shipping damage. Report any damage immediately to your supplier.
- Remove all protective films and tapes from the surfaces.
3.2 Placement
- Place the refrigerator on a firm, level surface capable of supporting its weight when fully loaded.
- Ensure adequate ventilation around the unit. Maintain a minimum clearance of 10 cm (4 inches) from walls or other objects to allow for proper air circulation, especially at the rear and top.
- Avoid placing the refrigerator in direct sunlight or near heat sources (e.g., ovens, radiators) to ensure efficient operation.
- Allow the refrigerator to stand upright for at least 2-4 hours before plugging it in. This allows the refrigerant to settle.

4. Operating Instructions
4.1 Power On
- After allowing the unit to stand for the recommended time, plug the power cord into a grounded electrical outlet.
- The digital display will illuminate, and the compressor will start.
4.2 Temperature Control

5. Maintenance
Regular maintenance ensures the longevity and efficient operation of your refrigerator.
5.1 Cleaning
- Interior: Clean the interior regularly with a mild, food-safe detergent and warm water. Rinse with clean water and dry thoroughly to prevent odors and bacterial growth. Remove shelves and shelf supports for easier cleaning.
- Exterior: Wipe down the stainless steel exterior with a soft cloth and a stainless steel cleaner. Avoid abrasive cleaners or scouring pads that can scratch the surface.
- Door Seals: Inspect and clean door seals regularly to ensure a tight seal. A damaged or dirty seal can lead to energy loss and inefficient cooling.
5.2 Condenser Coil Cleaning
- The condenser coils, typically located at the rear or bottom of the unit, should be cleaned periodically (e.g., every 3-6 months) to remove dust and debris.
- Always unplug the refrigerator before cleaning the condenser coils.
- Use a brush or vacuum cleaner to gently remove accumulated dust. Clean coils improve energy efficiency and cooling performance.
5.3 Defrosting
- If excessive ice buildup occurs, manually defrost the unit.
- Unplug the refrigerator and remove all contents. Leave the door open to allow ice to melt naturally.
- Do not use sharp objects or heating devices to accelerate defrosting, as this can damage the cooling system.
- Once defrosted, clean and dry the interior before restarting the unit.
