Installation

Unpack and inspect contents. Place on level, stable floor.

Choose location: Away from heat sources, with adequate ventilation on all sides.
Level the appliance: Adjust front feet to ensure proper door closure.
Set door hinge: Decide left or right opening; reverse if needed (see separate instructions).
Clean interior: Wipe inside with mild solution before first use.
Let it stand: After transport, let the freezer stand upright for several hours before plugging in.

WARNING! The freezer is heavy; use two people for moving. Ensure proper ventilation space around the unit.

First-Time Setup

After installation, plug into a dedicated power outlet.

Initial cooling: Turn on the freezer and set to desired temperature (recommended -18°C / 0°F).
SuperCool: Activate SuperCool function via control panel to rapidly cool the empty cabinet.
Load food: Once target temperature is reached, load food items, avoiding blocking air vents.
Alarm test: Familiarize yourself with the temperature alarm function.

CAUTION! Do not overload the freezer. Allow air circulation around food packages.

Connecting to Power

Use a properly grounded, dedicated wall outlet.

Ensure voltage matches appliance rating (220-240V~, 50Hz).
Do not use extension cords or multi-plug adapters.
Plug in securely. The control panel should illuminate.

Tip: For long absences, you can set the freezer to a slightly colder temperature, but it is not recommended to disconnect it.

Using the Freezer

Optimize storage for efficiency and food preservation.

Pre-cool food: Let hot food cool to room temperature before freezing.
Package properly: Use airtight containers or freezer bags to prevent freezer burn.
Organize: Place newer items behind older ones (FIFO). Label packages with date and contents.
Use shelves and bins: Adjust shelves to accommodate different sized items.
SuperCool: Activate this function several hours before adding a large quantity of unfrozen food.
Maximize storage: Do not block the internal air circulation vents.

WARNING! Do not store flammable, volatile, or explosive substances. Do not place heavy objects on top of the appliance.

NoFrost Technology

This system automatically prevents ice formation on the interior walls and food. A fan circulates dry air, and any moisture is collected on a hidden evaporator and periodically melted away. The water drains into a collection tray and evaporates. Benefit: No need for manual defrosting. Interior remains clear of ice. Energy consumption remains stable.

Care & Cleaning

Unplug the appliance before any cleaning. Use only mild, non-abrasive cleaners.

Exterior: Clean with a soft damp cloth and mild detergent. Dry thoroughly.
Interior: Empty the freezer. Clean shelves and bins with warm water and baking soda solution. Rinse and dry.
Door seals: Wipe clean to ensure a tight seal.
Condenser (rear): Vacuum dust from the rear grille periodically to maintain efficiency.

CAUTION! Never use sharp tools, steam cleaners, or abrasive/scouring agents. Do not pour water over the appliance.

Regulatory Information

This appliance complies with relevant EU Directives and standards. The refrigerant (R600a) is flammable but contained within a sealed system. Dispose of the appliance according to local WEEE (Waste Electrical and Electronic Equipment) regulations. For service, contact an authorized Liebherr service partner.

Troubleshooting

Symptom	Possible Cause	Corrective Action
Appliance not cooling	Not plugged in / Power outage / Incorrect setting	Check plug and power; ensure temperature setting is correct (e.g., -18°C).
Temperature alarm sounds	Door left open / New food load / Power failure	Check door seal; close door firmly; alarm will stop when temperature returns to normal.
Unusual noise	Appliance not level / Items touching rear wall / Normal compressor/fan sound	Level the appliance; ensure packages are not touching the interior rear wall.
Water inside or under appliance	Blocked drain hole / Defrost water collection tray full	Check and clear the drain hole (if accessible); ensure the appliance is level so water flows to tray.
Door does not seal properly	Dirty seal / Appliance not level / Door hinge misaligned	Clean door gasket; re-level the appliance; check door alignment.

Reset: Unplug for 5 minutes, then plug back in to reset electronics if display is erratic.

Service: Contact authorized Liebherr service. Do not attempt repairs yourself, especially involving the refrigerant circuit.
