The first launch of new household appliances is always an exciting moment that requires careful attention to detail. Refrigerators Liebherr are famous for their reliability and sophisticated electronics, so getting started correctly guarantees a long service life for the unit. Many users make the mistake of starting active operations immediately after unpacking, which can lead to damage to the compressor.
In this material we will analyze in detail all the stages, starting from the moment the device is delivered to the kitchen. You will learn why you need to wait a certain time, how to set the temperature correctly and what the indicators on the control panel mean. A competent approach to the first start-up will help to avoid typical problems and provide ideal storage conditions for your products from the first minutes.
Particular attention should be paid to preparing the installation site and checking the voltage in the network. Unstable electricity or improper placement of the device can negate all the benefits of a premium brand. Let's look at the process step by step to eliminate any risks.
Preparatory stage before the first start
Before connecting the power cord to the outlet, you need to make sure that the device was transported and installed correctly. If the refrigerator was transported lying down or at an angle, oil from the compressor could flow into the refrigerant circulation system. In this case immediate switching on it is strictly prohibited, as this will lead to water hammer and failure of the motor.
Leave the device in a vertical position in the room where it will be operated for at least 4-6 hours. This time is necessary for the oil to drain back into the compressor crankcase. It is also important to remove all transport elements: tape, foam pads and protective films.
⚠️ Attention: Do not install the refrigerator close to a wall or furniture. For normal operation of the cooling system Liebherr a gap of at least 5-7 cm is required at the back and sides for free air circulation.
Check the integrity of the door seals. They should fit snugly around the entire perimeter of the body. If you notice any creases or dirt, wipe them with a soft, damp cloth. The cleanliness of the seal affects the tightness of the chamber and energy consumption.
Electrical connection and safety requirements
Refrigerators Liebherr sensitive to voltage changes. For safe operation, it is recommended to use a separate grounded outlet. Using extension cords or power strips of poor quality may cause unstable operation of electronics or even fire.
Make sure that the voltage in your network meets the requirements indicated on the technical label located inside the camera or on the back wall. Typically this is a range 220-240 V at a frequency 50 Hz. If power surges often occur in your area, it is advisable to install a stabilizer.
After connecting the cord to the outlet, do not rush to load the products. Various indicators may light up on the control panel to indicate that the self-test is in progress. In modern models with a display, a welcome message or brand logo may appear.
| Parameter | Normal value | Action in case of deviation |
|---|---|---|
| Main voltage | 220-240 In | Use a stabilizer |
| Settling time | 4-6 hours | Wait until turned on |
| Room temperature | +10...+32 °C | Do not place batteries |
| Gap at the wall | 5-7 cm | Move the case aside |
Primary activation and temperature setting
After you are convinced that the connection is safe, you can proceed to activation. In most models Liebherr turning on occurs automatically when power is applied. However, some series require manually pressing a button on the control panel. Factory settings are usually set to the optimal mode: for the refrigerator compartment and for the freezer compartment. Let the device run idle for 6-12 hours. During this time, the unit will reach the required temperature, and the automation will turn off the compressor. On/Off or Power on the control panel.
Factory settings are usually set to optimal mode: +5°C for the refrigerator compartment and -18°C for the freezer. Let the device run idle for 6-12 hours. During this time, the unit will reach the required temperature, and the automation will turn off the compressor.
If your model is equipped with a system NoFrost, you may hear periodic fan noise or crackling noise - this is normal. This is how air circulates and the evaporator defrosts. Do not open the doors often during the first hours of operation, so as not to disturb the temperature balance.
☑️ Check before loading
To configure the parameters, use the touch buttons or the rotary encoder, depending on the series. Click on the + or - symbols until the desired value is reached. Remember that changing the settings does not take effect instantly, but after the completion of the current compressor operating cycle.
Interpretation of indicators and sound signals
Modern refrigerators Liebherr are equipped with an advanced diagnostic system. When you first turn it on, you may experience flashing lights or beeps. Most often, this is a signal Alarm, which indicates an increase in the temperature inside the chambers.
Since you are starting an empty refrigerator that has not yet cooled down, the temperature alarm is a normal situation. To turn off the sound signal, press the button Alarm or Info on the panel. The indicator will continue to light or flash until the temperature drops to the set temperature.
⚠️ Attention: If the emergency temperature indicator lights up red 12 hours after switching on, check that the doors are tightly closed and that there are no obstacles to air circulation.
It is also worth paying attention to the operating mode indicators. The symbol SuperFrost means accelerated freezing, and SmartFrost a special ice formation technology. In normal operation, these indicators should be turned off.
What does a flashing exclamation mark mean?
This is a universal fault or warning symbol. If it flashes along with the temperature indicator, the cooling process is in progress. If it lights up constantly after 24 hours of operation, diagnostics are required.
Loading food and entering operating mode
You can load food into the refrigerator only after it reaches operating mode. You can check this using indicators or simply by measuring the temperature with a thermometer placed in a glass of water in the center of the chamber. For the refrigerator compartment, the norm is +4...+6°C.
Do not fill the chamber completely with food on the first day. The heat load from large amounts of warm or room temperature food will cause the compressor to run continuously, which is not desirable for a new unit. Distribute supplies evenly without blocking the ventilation holes.
It is better to place food in the freezer in small portions, activating the function SuperFrost several hours before. This will ensure quick freezing and preserve the structure of the food. After complete freezing, do not forget to turn off the accelerated mode if it does not have an automatic shutdown.
Following the loading rules prolongs the life of the compressor and preserves the freshness of the products. Lieber Herr is famous for its freshness zones, such as BioFreshwhere a special microclimate is maintained. Place meat, fish, vegetables and fruits in these areas for maximum shelf life.
Frequently asked questions and simple troubleshooting
During operation, users often encounter issues that are not breakdowns. For example, heating the side walls of the case is a normal process of heat removal by the capacitor. You may also hear the sound of refrigerant gurgling, which indicates that the system is operating properly.
If the refrigerator makes a loud knocking or vibration, check the adjustment of the support legs. The device must stand strictly horizontally, but with a slight tilt back to allow the doors to close themselves. Use a building level for fine adjustments.
If a plastic smell appears in the first days of use, ventilate the chambers and wipe them again. This is a residual phenomenon from new materials that quickly passes. If the smell is strong and chemical, contact your service center.
⚠️ Attention: Specifications and control interfaces may vary depending on the specific model and year of manufacture. Always check the official user manual supplied with your device.
Correct operation from the very beginning is the key to ensuring that your Liebherr will delight you with silent operation and ideal cold for many years. Do not ignore electronic signals and keep the capacitor at the back of the device clean.
Why does the refrigerator not turn on immediately after connecting to the network?
In some models with electronic control, after power is applied, it takes time to start the system (up to 2-3 minutes). Also check that the plug is firmly inserted into the socket and that there is voltage in the network. If the power indicator is on, but the compressor is silent for more than 10 minutes, the surge protection may have tripped.
Do you need to defrost a Liebherr refrigerator before turning it on for the first time?
No, new refrigerators, especially those with the NoFrost system, do not require defrosting before turning it on for the first time. On the contrary, the inside of the cells should be dry and clean. You only need to defrost during operation if the model does not support automatic defrosting, but for modern Liebherrs this is rare.
What to do if the red temperature indicator is on?
The red indicator indicates that the temperature in the chamber is higher than safe. The first time you turn it on, this is normal until the refrigerator cools down. Press the mute button. If the indicator does not go out after 24 hours of operation of the empty refrigerator, check that the door is tightly closed or call a technician.
Is it possible to turn on a refrigerator in a freezer at sub-zero temperatures?
Most Liebherr refrigerators are designed to operate in a climate class from +10°C to +32°C (or +43°C). Operation in an unheated room at a temperature below +10°C can lead to solidification of the oil in the compressor and disruption of the thermostat, which will disable the equipment.
