Installation

Unpack and remove all packaging materials. Position in a suitable location.

  1. Choose location: Place on a solid, level floor away from heat sources and direct sunlight.
  2. Adjust feet: Use a wrench to adjust the feet until the appliance is perfectly level.
  3. Ventilation: Ensure at least 5 cm clearance at back and sides for air circulation.
  4. Electrical connection: Plug into a grounded 220-240V AC outlet. Do not use an extension cord.
  5. Door reversal (if needed): Follow instructions in separate door reversal leaflet.

WARNING! The appliance is heavy; use two people for moving. Ensure it is level to guarantee proper door seal and operation.

First-Time Setup

After installation, allow the appliance to stand upright for at least 4 hours before connecting to power.

  1. Initial power on: Plug in the appliance. The control panel will illuminate.
  2. Set temperature: Press the temperature button to set desired freezing level (recommended -18°C).
  3. Activate SuperFrost: If loading a large amount of unfrozen food, activate SuperFrost 24 hours in advance.
  4. Load food: Place food items inside, ensuring proper air circulation around packages.

CAUTION! Do not load the freezer with warm food immediately after switching on. Allow it to reach set temperature first.

Storage Guidelines

For optimal freezing and food preservation.

  1. Pre-cool food: Allow hot food to cool to room temperature before freezing.
  2. Package properly: Use airtight containers or freezer bags to prevent freezer burn.
  3. Label and date: Mark packages with contents and date of freezing.
  4. Do not overfill: Allow space between items for cold air circulation.
  5. Storage times: Adhere to recommended maximum storage times for different food types.

Tip: Use the upper baskets for items needed frequently and the bottom for long-term storage.

NoFrost Technology

The NoFrost system automatically prevents the formation of ice on the interior walls and food.

  1. How it works: A fan circulates cold, dry air throughout the compartment. Moisture is carried to a hidden evaporator where it condenses and is evaporated away.
  2. Benefits: No need for manual defrosting. Consistent temperature and humidity levels.
  3. Note: A thin layer of hoarfrost on food packages is normal and not a malfunction.

WARNING! Never attempt to remove ice or frost with sharp objects. If ice does build up (e.g., due to faulty door seal), contact service.

Energy Saving Tips

Ensure door seals are clean and intact. Set temperature to -18°C; lower settings increase consumption. Allow hot food to cool before freezing. Position away from heat sources. Do not open door unnecessarily or for prolonged periods.

Care & Cleaning

Disconnect from power before cleaning.

  1. Interior: Wipe with a soft cloth dampened with warm water and mild detergent. Rinse and dry.
  2. Exterior: Clean door and handle with a soft, damp cloth. Use proprietary stainless steel cleaner if applicable.
  3. Door seals: Wipe carefully to remove food residue and ensure a tight seal.
  4. Condenser (rear): Vacuum dust from the grille periodically to maintain efficiency.

CAUTION! Do not use abrasive cleaners, scouring pads, or solvents. Never pour water inside or over the appliance.
