Loading and Organizing

For optimal freezing and energy efficiency:

1. Pre-cool warm food: Allow 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 freezing date.
4. Organize by category: Use shelves for prepared meals, door bins for smaller items.
5. Do not overload: Ensure air circulation around packages.
6. Maximum loading: Do not exceed freezing capacity (18 kg/24h).

Tip: Place newer items at the back/bottom to use older items first (FIFO).

Energy Saving Tips

1. Set optimal temperature: -18°C is sufficient for long-term storage.
2. Minimize door openings: Plan removal of items to reduce cold loss.
3. Ensure door seals are clean and tight: Test by closing door on paper; if paper slips easily, seals may need replacement.
4. Position away from heat sources: Ovens, radiators, direct sunlight increase energy consumption.
5. Allow hot food to cool before freezing.
6. Keep condenser coils clean (located at rear or underneath).

Maintenance & Defrosting

1. Condensation drain: Check occasionally for blockages (if applicable).
2. Door seals: Clean with mild detergent; check for damage.
3. Interior: Remove shelves and bins for periodic cleaning (see Care section).
4. Exterior: Clean with damp cloth.

Note: If ice forms despite NoFrost, ensure door is closing properly and ambient temperature is within climate class range.

Care & Cleaning

Unplug appliance before cleaning.

1. Exterior: Use soft cloth dampened with mild detergent. Do not use abrasive cleaners.
2. Interior: Remove all food. Wash shelves, bins, and interior surfaces with warm water and mild detergent. Rinse and dry thoroughly.
