NoFrost Technology

Automatic defrosting system prevents ice build-up.

Operation: A fan circulates cold, dry air. Frost forms on a hidden evaporator.
Defrost Cycle: Automatically initiates at regular intervals. Heater melts frost; water is channeled to a collection tray and evaporates.
Benefits: No need for manual defrosting. Consistent temperature and humidity levels.
Maintenance: Ensure air vents inside the cabinet are not blocked by food items.

WARNING! Never use sharp objects to remove ice. If ice appears, check door seal and ensure NoFrost system is functioning.

Energy Saving Tips

Optimize usage to reduce electricity consumption.

Set correct temperature: -18°C is sufficient for long-term storage.
Minimize door openings: Plan removal of items to reduce cold air loss.
Ensure door seals are clean and tight: Test by closing door on a piece of paper; it should be held firmly.
Place in a cool location: Away from ovens, radiators, and direct sunlight.
Allow hot food to cool completely before freezing.
Keep the condenser coils (rear) clean and dust-free.

Care & Cleaning

Exterior: Clean with a soft, damp cloth and mild detergent. Dry thoroughly.
Interior: Remove all food. Wash shelves and drawers with warm soapy water. Rinse and dry.
Door seals: Wipe with water only to maintain elasticity.
Condenser: Vacuum the rear grille periodically to remove dust.
