NoFrost Technology

Automatic defrosting system eliminates manual defrosting.

How it works: A fan circulates cold air while a heater periodically melts frost on evaporator.
Water drainage: Melted frost water evaporates automatically.
Benefits: Consistent temperature, no ice buildup, better food preservation.
Maintenance: Ensure air vents are not blocked by food items.

Note: Slight humming during defrost cycle is normal.

Energy Saving Tips

Maximize efficiency to reduce electricity consumption.

Set optimal temperature: -18°C is sufficient for most foods.
Minimize door openings: Plan removal of items quickly.
Check door seals: Ensure they are clean and tight.
Allow hot food to cool before freezing.
Position away from ovens, radiators, direct sunlight.
Keep condenser coils (rear) dust-free.

Care & Cleaning
