Installation

Unpack and inspect contents. Ensure proper ventilation and level placement.

  2. Adjust feet: Use adjustable front feet to level the appliance.
  3. Ventilation: Maintain minimum clearance (as per specifications) at back and sides.
  4. Electrical connection: Plug into a grounded 220-240V AC outlet.
  5. Door reversal (if needed): Follow instructions in manual to change door hinge side.

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

First-Time Setup

After installation, allow the freezer to stand upright for several hours before connecting to power.

  1. Initial power on: Connect to power. The control panel will illuminate.
  2. Set temperature: Use the temperature control buttons to set the desired freezer temperature (recommended -18°C).
  3. Activate SuperFreeze: Press the SuperFreeze button when loading a large amount of unfrozen food.
  4. Load food: Once the target temperature is reached, begin loading food items.

CAUTION! Do not load large quantities of warm food at once. Allow the appliance to reach operating temperature first.

Specifications

Controls and Settings

The electronic control panel is located on the front exterior (often on the door).

Buttons & Display: POWER/On-Off, Temperature Up/Down, SuperFreeze, Alarm Reset/Mute, Child Lock.

Temperature Setting: Adjust between -16°C and -26°C. SuperFreeze: Activates maximum cooling for approx. 24 hours or until manually turned off.

Storage and Organization

Utilize shelves and drawers for efficient organization.

  1. Shelves: Use for flat items, frozen pizzas, boxes.
  2. Drawers: Ideal for loose items like vegetables, fruits, meat packages.
  3. Door bins: Store smaller items, ice packs, or frozen herbs.
  4. Labeling: Label and date packages for easy identification.
  5. Avoid overfilling: Allow air to circulate for consistent temperature.

Tip: Group similar items together. Pre-freeze berries or herbs on a tray before bagging to prevent clumping.

NoFrost Technology

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

  1. Operation: A fan circulates dry, cold air. Moisture is carried to a hidden evaporator where it freezes.
  2. Defrost Cycle: The system periodically heats the evaporator to melt this ice. The water drains away.
  3. Benefit: No need for manual defrosting. Interior remains dry and frost-free.
  4. Maintenance: Ensure air vents inside the cabinet are not blocked by food packages.

WARNING! Never use sharp objects to remove ice. If frost appears, check door seal and ensure NoFrost system is functioning (contact service).

Energy Saving Tips

Ensure door seals are clean and intact. Set temperature to -18°C, not colder. Allow hot food to cool before freezing. Regularly defrost (if manual model) or check NoFrost system. Position away from heat sources.

Care & Cleaning

Unplug before cleaning. Use mild detergent and warm water. Dry thoroughly.

CAUTION! Do not use abrasive cleaners, solvents, or steam cleaners. Do not pour water into the appliance or over the control panel.
