NoFrost Technology

Automatic system prevents ice formation on walls and food.

Benefits: No manual defrosting needed; consistent temperature; better food preservation.
Maintenance: Ensure air vents inside are not blocked by food packages.
Indicator: Frost symbol may appear briefly during defrost cycle (normal operation).

WARNING! Do not attempt to manually defrost or scrape ice as none should form. If frost appears, contact service.

Alarm Functions

Visual and audible alerts for various conditions.

High Temperature Alarm: Sounds if interior temperature rises above -12°C (adjustable). Door Open Alarm: Activates if door is open for more than 2 minutes. Power Failure Indicator: Flashing temperature display after power restoration indicates interruption occurred. To reset: Press ALARM button; check food safety if alarm was triggered.

Care & Maintenance

Unplug unit before any cleaning. Exterior: Clean with mild detergent and soft cloth. Interior: Empty and clean annually with baking soda solution (2 tbsp per liter warm water).

CAUTION! Never use abrasive cleaners, solvents, or sharp objects. Do not pour water into drainage channels.

Energy Saving Tips

Keep temperature at -18°C; lower settings increase energy use.
Ensure door seals are clean and tight; test with paper strip.
Allow hot food to cool before freezing.
Defrost food in refrigerator compartment, not at room temperature.
Keep unit away from ovens, heaters, and direct sunlight.
Minimize door opening frequency and duration.
