3. Setup Instructions
3.1 Unpacking
- Carefully remove all packaging materials, including foam and tape.
- Inspect the refrigerator for any shipping damage. If damage is found, do not operate the unit and contact customer service.
- Remove any internal packing materials, such as tape securing shelves or door racks.
3.2 Placement
- Place the refrigerator on a flat, stable surface that can support its weight when fully loaded.
- Ensure there is at least 4 inches (10 cm) of space around the back and sides of the unit for proper air circulation. This is crucial for the efficiency of the absorption cooling system.
- Avoid placing the unit in direct sunlight or near heat sources (e.g., ovens, radiators) as this can affect cooling performance.
- Important: After moving the refrigerator, allow it to stand upright for a minimum of 12 hours before plugging it into a power source. This allows the refrigerant to settle.
3.3 Reversible Door Installation
The door hinge can be reversed to open from either the left or right side. This process requires basic tools (screwdriver) and careful handling. Refer to the detailed diagram below for guidance.
