Using BioFresh & NoFrost

Optimize food storage with specialized compartments and frost-free operation.

BioFresh DrySafe: Low humidity compartment. Ideal for fish, meat, dairy, and delicatessen products.
BioFresh HydroSafe: High humidity compartment. Perfect for fruits, vegetables, and herbs.
Adjust drawers: Use the humidity control slider on the front of each BioFresh drawer.
NoFrost Operation: The system runs automatically. Ensure air vents inside are not blocked by food packages.
Defrosting: Not required. Any minimal moisture is evaporated automatically.

WARNING! Do not cover the air circulation vents inside the appliance. This ensures proper NoFrost function and even temperature.

Energy Saving Tips

Ensure efficient operation to minimize energy consumption.

Set temperature to -18°C; lower settings increase energy use.
Keep door seals clean and ensure door closes tightly.
Allow hot food to cool completely before placing inside.
Open door as infrequently and for as short a time as possible.
Ensure adequate ventilation space around the appliance.
Use SuperFreeze only when necessary.
