Tip: Keep an inventory list on the door to minimize search time and door-open duration.

Energy Saving Tips

Maximize efficiency and minimize operating costs.

Location: Install away from heat sources (oven, radiator, direct sunlight).
Temperature Setting: Maintain -18°C; lower settings increase energy use.
Door Seals: Check regularly for tightness. Clean seals to ensure proper closure.
Door Opening: Open door only when necessary and close quickly.
Defrosting: NoFrost system eliminates need for manual defrosting.
Ventilation: Keep rear grille and side clearances free of dust and obstructions.

WARNING! Do not use electrical devices inside the freezer to scrape ice (NoFrost makes this unnecessary).

Maintenance & Defrosting

The NoFrost system automatically prevents ice buildup in the freezer compartment. The BioFresh compartment may require occasional manual defrosting if a thin layer of frost forms.

To defrost BioFresh: Remove all food, turn off unit or set to 0°C, place towels to catch water. Allow frost to melt naturally.
Never use sharp objects or heaters to speed up defrosting.
After defrosting, wipe dry, restart unit, and reload food once temperature is reached.

Care & Cleaning

Unplug before cleaning. Use mild detergent and warm water. Do not use abrasive cleaners or solvents.

Interior: Clean shelves, drawers, and liners with soft cloth and mild solution. Dry thoroughly.
Exterior: Clean door and control panel with damp cloth. Polish stainless steel surfaces (if applicable) with recommended cleaner.
Door Seals: Wipe clean to maintain elasticity and seal.
Condenser Coil (rear): Vacuum dust periodically to maintain efficiency.

CAUTION! Never use steam cleaners, sharp tools, or harsh chemicals. Do not wash removable parts in dishwasher unless specified.
