5. Avoid blocking air vents: Ensure proper air circulation for NoFrost system.

Tip: Pre-freeze items in portions for easier use later.

NoFrost Technology

How the NoFrost system works and its benefits.

1. Operation: A fan circulates cold, dry air throughout the compartment, preventing humidity from condensing and forming ice.
2. Defrost Cycle: Automatically melts frost from the evaporator; water is channeled to a collection tray and evaporates.
3. Benefits: No manual defrosting needed, consistent temperature, better food preservation, energy efficiency maintained.
4. Maintenance: Keep air vents clear; ensure door seals are clean and intact.

WARNING! Do not cover or block the air vents inside the freezer.

Energy Saving Tips

Maximize efficiency and reduce operating costs.

• Set optimal temperature: -18°C (0°F) is sufficient for long-term storage.
• Use SuperCool only when necessary (e.g., after shopping).
• Ensure door seals are airtight: test by closing door on a piece of paper; it should be held firmly.
• Allow hot food to cool to room temperature before freezing.
• Open door as infrequently and briefly as possible.
• Keep freezer well-stocked (but not overloaded) for better thermal mass.
• Ensure adequate ventilation around the appliance.

Care & Cleaning

Unplug before cleaning. Use mild, non-abrasive cleaners.

1. Exterior: Wipe with soft, damp cloth. Dry thoroughly.
2. Interior: Remove all food. Clean shelves and drawers with solution of warm water and mild detergent. Rinse and dry.
3. Door Seals: Clean gently with water and dry to maintain elasticity.
4. Condenser Coils (rear or bottom): Vacuum dust periodically to maintain efficiency.
5. Defrost Drain (if accessible): Check and clear if necessary (though NoFrost minimizes this need).

CAUTION! Never use sharp tools, abrasive cleaners, or harsh chemicals. Do not pour water directly into the appliance.
