Setup
Unpacking
Carefully remove all packaging materials, including tape and temporary labels. Dispose of packaging responsibly. Ensure no parts are left inside the refrigerator or freezer compartments.
Placement
Position the refrigerator on a firm, level floor. Allow at least 2 inches (5 cm) of space between the back and sides of the refrigerator and any adjacent walls or cabinets for proper air circulation. Avoid placing the appliance in direct sunlight or near heat sources.

Leveling
Use the adjustable leveling feet at the bottom of the refrigerator to ensure the appliance is stable and level. A level refrigerator operates more efficiently and prevents door alignment issues.
Power Connection
Plug the refrigerator into a dedicated, grounded 115V, 60Hz AC outlet. Do not use extension cords or adapter plugs. Allow the refrigerator to stand for at least 4 hours before plugging it in to allow refrigerants to settle.
Operating
Temperature Control
Your refrigerator features electronic temperature controls for precise temperature management in both the fresh food and freezer compartments.
- Refrigerator Temperature Control: Located inside the fresh food compartment, this control allows you to adjust the cooling level. Settings typically range from 'Cold' to 'Coldest'.
- Freezer Temperature Control: A separate dial or slider in the freezer compartment allows you to set the desired freezer temperature, usually from 'Min' to 'Max'.

Maintenance
Cleaning
- Interior: Clean the interior regularly with a solution of mild soap and warm water. Rinse thoroughly and dry. Remove shelves and drawers for easier cleaning.
- Exterior: Wipe the exterior surfaces with a soft cloth and mild detergent. For the black finish, avoid abrasive cleaners that could scratch the surface.
- Door Gaskets: Clean the door gaskets (seals) with a damp cloth to ensure they remain pliable and maintain a tight seal.
Defrosting
This top-freezer refrigerator is designed with an automatic defrost system for the fresh food compartment. The freezer compartment may require occasional manual defrosting if excessive ice buildup occurs. Refer to the full manual for detailed defrosting instructions if needed.
Troubleshooting
Before contacting service, review the following common issues and their solutions:
- Refrigerator Not Cooling: Check if the power cord is securely plugged in. Ensure the temperature controls are set correctly. Verify that the door is fully closed and not obstructed.
- Unusual Noises: Minor noises like humming or gurgling are normal as the refrigerant circulates. Loud or persistent noises may indicate an issue; ensure the refrigerator is level and not touching walls.
- Internal Light Not Working: Check if the bulb needs replacement. Ensure the refrigerator is receiving power.
- Excessive Ice Buildup in Freezer: Ensure the freezer door is sealing properly. Avoid leaving the door open for extended periods.
