Installation

Unpack and inspect contents. Position on a level, stable floor.

1. Choose location: Place away from heat sources, with adequate ventilation (min. 5 cm clearance on sides and back).
2. Adjust feet: Use a spirit level to ensure the appliance is perfectly horizontal.
3. Set door hinge: Install door on preferred side using included hinge kit.
4. Connect to power: Plug into a grounded 220-240V AC, 50Hz outlet. Use a dedicated circuit.
5. Wait before loading: Allow the freezer to stand upright for at least 4 hours after transportation before switching on.

WARNING! The appliance is heavy; use two people for lifting and moving. Ensure the floor can support the weight.

First-Time Setup

After installation, power on the freezer and configure initial settings.

1. Initial cooling: Turn on the appliance and set to maximum cooling for the first 24 hours.
2. Set temperature: Use the control panel to set the desired freezer temperature (recommended -18°C).
3. Activate SuperCool: Press the SuperCool button before loading large amounts of unfrozen food.
4. Set child lock: Press and hold the lock button for 3 seconds to activate the control panel lock.
5. Load food: Distribute food evenly across shelves, allowing air circulation.

CAUTION! Do not block air vents inside the cabinet. Overloading can reduce efficiency.

Temperature Management

For optimal food preservation and energy efficiency.

1. Recommended temperature: Set to -18°C for long-term storage of frozen food.
2. Loading warm food: Use the SuperCool function beforehand to compensate for temperature rise.
3. Avoid frequent door openings: Plan removal of items to minimize cold air loss.
4. Check seal: Ensure the door gasket is clean and sealing properly.

Tip: Use a separate thermometer to occasionally verify the internal temperature.

NoFrost Technology

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

1. How it works: A fan circulates cold, dry air throughout the cabinet, preventing moisture from condensing and freezing on surfaces.
2. Benefits: No need for manual defrosting. Consistent temperature and humidity levels.
3. Maintenance: The evaporator behind the rear panel defrosts automatically. Ensure air vents are not blocked by food packages.

WARNING! Never use sharp objects to remove ice. If ice forms, it indicates a problem with the door seal or that the NoFrost system requires service.

Energy Saving Tips

Maximize efficiency to reduce electricity consumption.

• Position in a cool room, away from ovens or direct sunlight.
• Ensure door seals are airtight.
• Allow hot food to cool to room temperature before freezing.
• Keep the freezer well-stocked (a full freezer retains cold better), but do not overpack.
• Regularly clean the condenser coil at the back (if accessible) to maintain efficiency.

Care & Cleaning

Unplug the appliance before any cleaning.

1. Interior: Wipe with a soft cloth dampened with a mild detergent solution. Do not use abrasive cleaners.
2. Shelves and bins: Remove and wash separately with warm soapy water. Dry thoroughly before replacing.
3. Door gasket: Clean carefully with water and a soft cloth to maintain seal integrity.
4. Exterior: Wipe with a damp cloth. For stainless steel models, use appropriate cleaner.
5. Condenser: Vacuum the rear grille periodically to remove dust.

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