  2. Use dedicated circuit; avoid extension cords.
  3. Plug directly into wall outlet.
  4. Check that power cord is not pinched or damaged.

Tip: For long absences, empty freezer, clean, disconnect power, and leave door slightly open.

Using NoFrost Technology

NoFrost automatically prevents ice buildup.

  1. Operation: Fan circulates dry air to prevent frost formation.
  2. Defrosting: Not required; system handles automatically.
  3. Water drainage: Condensed water evaporates automatically.
  4. Energy efficiency: Maintains consistent temperature without manual defrost cycles.

WARNING! Do not block air vents inside freezer. Keep food packaged to prevent drying.

Energy Saving Tips

Keep door closed as much as possible. Ensure seals are clean and intact. Position away from heat sources. Allow hot food to cool before freezing. Maintain -18°C for optimal efficiency. Regularly defrost if minimal frost appears (though NoFrost minimizes this).

Care & Cleaning

Unplug before cleaning. Use mild detergent and warm water; never use abrasive cleaners.

  1. Interior: Remove shelves and drawers; wash with soapy water.
  2. Exterior: Wipe with soft damp cloth.
  3. Door seals: Clean gently to maintain airtight seal.
  4. Condenser: Vacuum rear grille annually to remove dust.
