Label and date: Use labels to track storage time.
Allow air circulation: Do not block air vents inside the compartment.

Tip: Keep frequently used items at the front for easy access and reduce door opening time.

NoFrost Technology

The NoFrost system automatically prevents ice formation on interior walls and shelves.

Operation: A fan circulates cold air evenly; moisture is carried to an evaporator where it condenses and evaporates.
Benefits: No need for manual defrosting; consistent temperature throughout; better food preservation.
Maintenance: Ensure air vents are not obstructed by food packages.

Note: A thin layer of frost may occasionally appear but will clear automatically. This is normal.

Energy Saving Tips

Maximize efficiency and reduce electricity consumption.

Set optimal temperature: -18°C (0°F) is sufficient for long-term storage.
Minimize door openings: Plan removal of items to reduce cold air loss.
Ensure proper seals: Check door gaskets regularly for tight closure.
Place in a cool location: Away from ovens, heaters, and direct sunlight.
Allow hot food to cool before freezing.

Unplug the appliance before any cleaning. Never use abrasive cleaners or sharp objects.

Interior: Wipe with a soft cloth dampened with mild soapy water. Rinse with clean water and dry.
Exterior: Clean door and control panel with a soft, dry cloth.
