This user manual provides essential information for the safe and efficient operation of your new Liebherr GP 1366 freestanding upright freezer. Please read these instructions carefully before installation, first use, or maintenance to ensure optimal performance and to prevent damage or injury. Keep this manual in a safe place for future reference.
2. Safety Information
Always adhere to the following safety guidelines to prevent accidents and ensure the longevity of your appliance:
- Electrical Safety: Ensure the freezer is connected to a properly grounded electrical outlet with the correct voltage. Do not use extension cords or multiple socket adapters. Disconnect the appliance from the power supply before cleaning or maintenance.
- Ventilation: Ensure adequate air circulation around the appliance. Do not block ventilation openings.
- Flammable Materials: Do not store explosive substances or products containing flammable propellants (e.g., aerosol cans) inside the freezer.
- Children: This appliance is not intended for use by persons (including children) with reduced physical, sensory, or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety. Children should be supervised to ensure that they do not play with the appliance.
- Disposal: When disposing of the appliance, ensure that the refrigerant circuit is not damaged. Contact your local authority for information on proper disposal methods.
3. Setup and Installation
Proper installation is crucial for the performance and safety of your freezer.
3.1 Unpacking
Carefully remove all packaging materials. Inspect the freezer for any signs of transport damage. If damage is found, contact your supplier immediately. Keep packaging materials out of reach of children.
3.2 Placement
- Place the freezer on a firm, level surface to prevent vibrations and noise.
- Ensure sufficient ventilation space around the appliance. Maintain a minimum distance of 5 cm from walls and other appliances.
- Avoid placing the freezer near direct sunlight, heat sources (e.g., ovens, radiators), or in areas with extreme temperature fluctuations.
3.3 Electrical Connection
Before connecting, ensure the voltage and frequency indicated on the rating plate match your household power supply. The appliance must be properly grounded. Do not connect the freezer to the power supply for at least 4 hours after moving it to allow the refrigerant to settle.
3.4 Initial Startup
After the waiting period, plug in the freezer. The internal temperature will gradually decrease. Allow the appliance to run for several hours (e.g., 4-6 hours) before loading it with food to ensure it reaches the optimal freezing temperature.

Each drawer is filled with various frozen food items, such as vegetables, meat, and prepared meals, and is labeled with a number for organization. The control panel is located at the top of the unit.
4. Operating Instructions
Understanding the controls and proper food storage techniques will maximize your freezer's efficiency.
4.1 Control Panel
The control panel, located at the top of the freezer, typically includes:
- Temperature Display: Shows the current internal temperature.
- Temperature Adjustment Buttons: Used to set the desired freezing temperature.
- SuperFrost/Fast Freeze Button: Activates rapid freezing for fresh food.
- Alarm Indicator: Illuminates or sounds if the internal temperature rises above a safe level.
Refer to the specific markings on your appliance's control panel for detailed functions.
4.2 Freezing Fresh Food
- Only freeze fresh, undamaged food.
- Package food in airtight containers or freezer bags to prevent dehydration and flavor transfer.
- Do not exceed the maximum freezing capacity stated in the specifications.
- For best results, activate the SuperFrost/Fast Freeze function several hours before placing large quantities of fresh food into the freezer.
4.3 Storage of Frozen Food
- Organize food using the transparent drawers for easy access and inventory management.
- Label all packages with the date of freezing and contents.
- Adhere to recommended storage times for different food types to maintain quality and safety.
5. Maintenance and Cleaning
Regular maintenance ensures optimal performance and hygiene.
5.1 Cleaning the Interior
- Disconnect the freezer from the power supply before cleaning.
- Remove all food and drawers.
- Clean the interior with a soft cloth, lukewarm water, and a mild, food-safe cleaning agent. Avoid abrasive cleaners or solvents.
- Dry all surfaces thoroughly before reconnecting the power.
5.2 Defrosting
This freezer requires manual defrosting when a layer of ice approximately 5 mm thick has formed. Excessive ice buildup reduces efficiency.
- Disconnect the freezer from the power supply.
- Remove all frozen food and store it in a cool place (e.g., wrapped in blankets or in another freezer).
- Leave the freezer door open to allow the ice to melt naturally. Place towels or a shallow tray at the bottom to collect water. Do not use sharp objects or heating devices to speed up defrosting.
- Once defrosted, clean and dry the interior thoroughly before reconnecting power and returning food.
5.3 Power Outage
In case of a power outage, keep the freezer door closed to maintain the internal temperature for as long as possible. The insulation will help keep food frozen for several hours. Check food quality before consumption after a prolonged outage.
6. Troubleshooting
Before contacting customer service, review these common issues and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Freezer not cooling | No power supply; thermostat set too high; door not closed properly. | Check power plug and fuse; adjust thermostat to a colder setting; ensure door is fully closed and seal is intact. |
| Excessive ice buildup | Door left open too long; warm food placed inside; faulty door seal. | Defrost the appliance; ensure door is closed quickly; allow food to cool before freezing; check and replace door seal if necessary. |
| Unusual noises | Appliance not level; objects touching the back wall; normal operating sounds. | Adjust leveling feet; ensure nothing is touching the back; gurgling/hissing sounds are normal for refrigerant. |
