Unpacking and Placement

1. Remove all packaging materials, including foam and adhesive tape.
2. Inspect the freezer for any shipping damage. Report any damage to the retailer immediately.
3. Place the freezer on a firm, level floor in a dry, well-ventilated area.
4. Ensure there is at least 5 inches (12.7 cm) of space around the freezer for proper air circulation. Avoid placing it near heat sources or in direct sunlight.
5. Allow the freezer to stand upright for at least 4-6 hours before plugging it in. This allows the refrigerant fluids to settle.
