Food Storage Guidelines

For optimal food preservation and energy efficiency.

1. Pre-cool hot foods before placing in freezer.
2. Package foods airtight to prevent freezer burn and odor transfer.
3. Label packages with contents and date.
4. Distribute items evenly across shelves.
5. Do not overload; leave space for air circulation.
6. Recommended storage times: Meat (6-12 months), vegetables (8-12 months), bread (3-6 months).

Tip: Use SuperFrost function when adding large quantities of unfrozen food.

NoFrost Technology

Automatically prevents ice formation inside freezer compartment.

1. How it works: Circulates cold, dry air to remove moisture before it can form ice.
2. Benefits: No manual defrosting needed; consistent temperature; better food preservation.
3. Maintenance: Ensure air vents are not blocked by food items.
4. Note: A thin layer of frost may appear temporarily during high humidity; this will clear automatically.

WARNING! Do not attempt to manually defrost; NoFrost system handles it automatically.

Energy Saving Tips

Maximize efficiency and reduce electricity consumption.

• Set temperature to -18°C; lower settings increase energy use.
• Ensure door seals are clean and tight.
• Open door as briefly as possible.
• Place freezer in cool location away from heat sources.
• Allow hot foods to cool before freezing.
• Regularly clean condenser coils (located at rear).

Care & Cleaning

Unplug before cleaning. Use mild soap solution; never use abrasive cleaners or solvents.

1. Exterior: Wipe with damp cloth; dry thoroughly.
2. Interior: Remove all food; clean shelves and compartments with baking soda solution (1 tbsp per liter water).
3. Door seals: Clean with water only to maintain elasticity.
4. Condenser coils: Vacuum dust every 6 months for optimal efficiency.
5. Defrost drain: Check and clean if necessary (located at rear inside).

CAUTION! Never use sharp objects to remove ice; NoFrost system prevents buildup. Do not clean with steam or high-pressure cleaners.
