3. Setup
3.1 Unpacking
- Remove all packaging materials, including protective films and tapes.
- Check the appliance for any transport damage. Report any damage immediately to your retailer.
3.2 Placement
- Place the freezer on a firm, level surface.
- Ensure adequate ventilation around the appliance. Leave at least 10cm clearance at the back and sides for proper air circulation.
- Avoid placing the freezer in direct sunlight or near heat sources (e.g., radiators, ovens).

3.3 Leveling
Adjust the front leveling feet to ensure the appliance is stable and level. This prevents vibrations and excessive noise.

- Activate this function several hours before placing large quantities of fresh food into the freezer.
- The quick freeze function will automatically switch off after approximately 24 hours, or it can be manually deactivated.
4.4 Food Storage Guidelines
- Always wrap food properly to prevent dehydration and odor transfer.
- Do not place hot food directly into the freezer. Allow it to cool down first.
- Avoid overloading the drawers, as this can impede air circulation.
- Refer to the packaging for recommended storage times of frozen foods.
5. Maintenance
5.1 Cleaning

- Exterior Cleaning: Wipe the exterior surfaces with a damp cloth and a mild detergent. Dry with a soft cloth.

5.2 Defrosting
This appliance features a frost-free system, which means manual defrosting is generally not required. Any minor frost build-up will be automatically removed.
5.3 Door Seal Care
Regularly check and clean the door seals to ensure they are free from food particles and remain flexible. A clean, tight seal helps maintain energy efficiency.
5.4 Power Outage
In case of a power outage, keep the freezer door closed to maintain the internal temperature for as long as possible. The freezer can typically keep food frozen for several hours if the door remains shut.
