Installation

Unpack and inspect contents. Position in a suitable location.

1. Choose Location: Place on a level, solid floor away from heat sources and direct sunlight. Ensure adequate ventilation around the unit.
2. Adjust Feet: Level the appliance using the adjustable front feet.
3. Set Door Swing (if needed): Reverse the door using the supplied hinge kit and instructions.
4. Electrical Connection: Plug into a dedicated 120V AC, 60Hz grounded outlet. Do not use an extension cord.
5. Initial Standby: Let the appliance stand upright for at least 4 hours before first switching on.

WARNING! The appliance is heavy; use two people for moving and installation to avoid injury.

First-Time Setup

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

1. Power On: Plug in the appliance. The control panel will illuminate.
2. Set Temperature: Use the '+' and '-' buttons to set the desired freezer temperature (recommended -18°C / 0°F).
3. Activate SuperFrost: Press the SuperFrost button 24 hours before loading large quantities of unfrozen food.
4. Configure Alarm: Test the door alarm by holding the door open for more than 2 minutes.
5. ECO Mode: Consider activating ECO mode for energy-efficient operation in stable conditions.

CAUTION! Do not overload the appliance during initial cool-down. Allow temperature to stabilize first.

Alarm: Sounds if the door is ajar or if there is a significant temperature rise. Press the Alarm button to silence it (does not solve the underlying issue).

ECO Mode: Optimizes compressor run time for lower energy consumption in stable environments.

Storage Organization

Organize food for optimal freezing and easy access.

1. Use drawers for smaller items, frozen vegetables, and prepared meals.
2. Use shelves for larger items like meat packages, pizzas, and baked goods.
3. Label and date all packages before storing.
4. Do not block air vents inside the cabinet.
5. Allow hot food to cool to room temperature before freezing.
6. Leave space between packages for air circulation during initial freezing.

Tip: Group similar foods together (meats, vegetables, ready meals) for efficient inventory management.

SuperFrost Function

This function rapidly lowers the temperature to prepare for freezing fresh food, preserving texture and nutrients.

1. Activation: Press the SuperFrost button at least 24 hours before adding a large amount of unfrozen food (more than 5kg). The LED will light up.
2. Loading: Once the SuperFrost period is complete (or after 24 hours), load the food to be frozen. Spread packages across shelves/drawers for best results.
3. Deactivation: The function switches off automatically after approx. 65 hours. You can also press the SuperFrost button again to deactivate it manually. The LED turns off.

WARNING! Using SuperFrost increases energy consumption. Use only when necessary for large loads.

Alarm System

The freezer is equipped with a visual and audible alarm.

Door Alarm: Triggers if the door is left open for more than approximately 2 minutes. Close the door firmly to deactivate.

Temperature Alarm: Triggers if the internal temperature rises significantly above the set point (e.g., due to power failure, door ajar, or system fault).

Power Failure Indicator: A symbol may appear on the display after power is restored, indicating a previous interruption.

Silencing the Alarm: Press the Alarm button on the control panel. Investigate and resolve the cause immediately.

Care & Cleaning

Unplug the appliance before any cleaning. Never use sharp tools, abrasive cleaners, or solvents.

1. Interior: Defrost manually if ice buildup exceeds 5mm. Remove food, turn off appliance, and leave door open. Speed up by placing bowls of warm water inside. Wipe out water with a soft cloth. Dry thoroughly before restarting.
2. Exterior & Door Seals: Clean with a soft damp cloth and mild detergent. Wipe door gaskets carefully to maintain seal.
3. Condenser Coil (rear): Vacuum the rear grille periodically to remove dust for efficient operation.
4. Drawers & Shelves: Wash with warm soapy water, rinse, and dry completely before reinstalling.

CAUTION! Do not use electrical appliances inside the freezer to speed up defrosting. Never scrape ice with sharp objects.
