5. Air circulation: Do not overpack; allow air to circulate around items.
6. Pre-freezing: Spread items out initially, then stack once frozen.

Tip: Group similar items together for easy finding. Use airtight containers to prevent freezer burn.

NoFrost Technology

The NoFrost system automatically prevents ice buildup.

1. How it works: Cold air circulates in a closed system; moisture is collected and evaporated.
2. Benefits: No manual defrosting needed. Consistent temperature throughout. Better food preservation.
3. Maintenance: Ensure air vents inside are not blocked by food packages.
4. Indicator: No frost or ice should form on interior surfaces under normal operation.

Note: The compressor may run more frequently during defrost cycles, which is normal operation.

Energy Saving Tips

Proper use reduces energy consumption.

• Maintain temperature at -18°C; lower settings increase energy use.
• Ensure door seals are clean and tight.
• Open door minimally and briefly.
• Allow hot food to cool before freezing.
• Keep freezer at least 2/3 full for optimal efficiency (use water bottles if needed).
• Regularly clean condenser coils (located at back or bottom).
• Position away from heat sources (oven, radiator, direct sunlight).

Care & Cleaning

Unplug before cleaning. Never use sharp objects or abrasive cleaners.

1. Exterior: Clean with soft cloth dampened with mild detergent solution.
2. Interior: Remove all food. Clean with solution of 2 tablespoons baking soda per liter of warm water.
3. Shelves and bins: Remove and wash separately with mild detergent.
4. Door seals: Wipe with clean water only; check for debris that might prevent sealing.
5. Condenser coils: Vacuum dust from rear coils every 6-12 months.
6. Drain hole (if applicable): Check and clear if present.

CAUTION! Never use chemical cleaners, scouring pads, or steam cleaners. Do not pour water into interior.
