Storage Recommendations

For optimal freezing and energy efficiency.

  1. Pre-cool food: Allow hot food to cool to room temperature before freezing.
  2. Package properly: Use airtight containers or freezer bags to prevent freezer burn.
  3. Label and date: Mark packages with contents and date.
  4. Do not overfill: Leave space between items for air circulation.
  5. Organize: Place frequently used items in front. Use baskets for small items.
  6. Maximum load: Do not exceed maximum freezing capacity (e.g., 10 kg/22 lbs per 24 hours).

Tip: Spread new items across different shelves for faster freezing.

NoFrost Technology

Automatically prevents ice formation in freezer compartment.

  1. How it works: Circulates cold, dry air to remove moisture before it condenses.
  2. Benefits: No need for manual defrosting. Consistent temperature. More storage space.
  3. Maintenance: Ensure air vents inside are not blocked by food packages.
  4. Note: A thin layer of frost may appear temporarily after door is opened frequently; this will clear automatically.

WARNING! Do not cover or block interior air vents.

Energy Saving Tips

Close door properly after use. Ensure seals are clean and intact. Set temperature to recommended -18°C (0°F). Use SuperCool only when necessary. Place away from heat sources. Allow hot food to cool before freezing.

Care & Cleaning

Unplug before cleaning. Interior: Use mild detergent and warm water. Wipe dry. Exterior: Use soft cloth with mild cleaner. Door seals: Clean with water only; check for damage. Condenser (rear): Vacuum dust annually.

CAUTION! Do not use abrasive cleaners, solvents, or steam. Do not pour water inside or over appliance.
