Maintenance & Defrosting

The NoFrost system eliminates the need for manual defrosting. Water from defrosting evaporates automatically.

  1. Regular cleaning: Clean interior and door seals periodically (see Care & Cleaning).
  2. Check door seals: Ensure they are clean and intact to maintain efficiency.
  3. Condensation drain: No user service required under normal operation.
  4. Ventilation: Keep air vents at rear clear of dust and obstructions.

WARNING! Never use sharp objects to remove ice (not required with NoFrost). Do not use electrical devices inside to speed defrosting.

Energy Saving Tips

Keep door closed as much as possible. Ensure door seals tightly. Position away from ovens and heaters. Allow hot food to cool before freezing. Set optimal temperature (-18°C). Regularly defrost if ice buildup occurs (minimal with NoFrost).

Care & Cleaning

Unplug before cleaning. Use mild detergent and warm water. Dry thoroughly.

  1. Interior: Wipe shelves, walls, and bins with a soft cloth.
  2. Door seals: Clean gently to remove food residue.
  3. Exterior: Wipe with a damp cloth; use approved stainless steel cleaner if applicable.
  4. Condenser coil (rear): Vacuum dust periodically to maintain efficiency.

CAUTION! Do not use abrasive cleaners, solvents, or steam cleaners. Never pour water inside or over the appliance.
