A new household appliance in the kitchen is always a joy and an expectation of comfort, but the first launch often raises questions among the owners. Refrigerators Liebherr are famous for their reliability and complex electronics, which require proper activation before operation. Unlike old mechanical models, modern units of the German brand have many digital functions that must be configured immediately after connecting to the power supply.
Before pressing the power button, it is extremely important to make sure that the device has stood in an upright position for the required time after transportation. Oil in the compressor it takes time to drain back into the crankcase, otherwise starting the engine can lead to its rapid failure. Typically, manufacturers recommend a pause of 2 to 4 hours, but in the cold season it is better to increase this interval.
The activation process not only starts cooling, but also conducts self-diagnosis of the system. If you ignore the preparation steps, smart electronics may lock up or generate false alarms. Let's look at each step in detail so that your equipment will serve for many years without failures or breakdowns.
Preparation for the first start and checking the conditions
Installing a refrigerator is not just placing it in the kitchen, but a set of measures to ensure stable operation of the compressor. First of all, it is necessary to remove all transport elements: tape, foam stands and fixing tapes inside the cameras. Pay special attention to drawer latches and shelves, which are often forgotten to be removed, which leads to plastic deformation during vibration.
The location of the device plays a critical role in heat transfer. The rear grille of the condenser should be at least 5-10 cm from the wall for free air circulation. If the refrigerator is built-in, make sure that the ventilation holes in the furniture are not blocked and comply with the instructions for the specific model Liebherr.
⚠️ Attention: It is strictly forbidden to connect the device to the electrical network through an extension cord or tee. Use only a separate grounded outlet that can withstand the compressor's inrush currents.
After installation on a flat surface, check that the housing is level using a building level. Height adjustment is carried out by twisting or unscrewing the front support legs. Correct installation ensures that the doors will close on their own under the influence of gravity, ensuring tightness.
☑️ Check before turning on
Connecting to the electrical network and primary activation
When the preparatory steps are completed, you can proceed to the electrical connection. Insert the plug into the outlet - the indicators on the control panel should light up. On models with a display SmartDevice or TouchDisplay the screen will light up, showing the brand logo or the current temperature in the chambers.
In some models, activation occurs automatically immediately after power is applied. However, if the device was in transport mode (demo mode), it must be taken out of this state. This often requires a long press on the power button or key combination specified in the manual.
After applying voltage, the compressor may not start immediately. Electronics checks sensors and security systems, which takes from a few seconds to a couple of minutes. At this moment a characteristic click is heard relay, after which the engine starts working, creating a slight hum.
For the first hours of operation, the refrigerator can operate in enhanced mode. This is normal, since the system needs to cool the internal volume from room temperature to the set values. Do not load the chambers with food during this period, let the equipment return to operating mode.
Setting the temperature and functions
Modern refrigerators Liebherr allow you to flexibly adjust the climate in each zone. The standard temperature for the refrigerator compartment is +4...+5°C, and for the freezer - -18°C. The parameters are changed through the touch panel or mechanical controls depending on the series.
The function SuperFrostis designed for quick freezing of fresh products. When activated, the compressor works continuously, lowering the temperature in the freezer to extreme values. This mode should be used only when loading a large volume of products, having previously defrosted the chamber, if necessary.
| Function | Purpose | Recommended operating time |
|---|---|---|
| SuperFrost | Quick freezing | Until 65 hours (automatic shutdown) |
| SmartFrost | Reduce ice formation | Continuous |
| Holiday Mode | Vacation mode (saving) | Long absence |
| SuperCool | Fast cooling | Up to 12 hours |
Don't forget about the function Holiday Mode (Vacation mode). If you are away for a long time, this mode maintains the temperature in the refrigerator compartment at about +14°C, preventing the appearance of mold and odor, while the freezer continues to operate as normal.
Use of SmartDevice and Wi-Fi system
Many modern models are equipped with a module SmartDevicethat allows you to control the refrigerator via a smartphone. To activate this function, you need to download the application Liebherr SmartDevice and register the device. This opens up access to remote temperature monitoring and setting modes.
The pairing process usually looks like this: on the refrigerator panel, press the button with the Wi-Fi or SmartDevice symbol until a sound signal appears. Then, in the application on your phone, select the model and enter the code displayed on the device display.
⚠️ Attention: The Wi-Fi module consumes electricity even in standby mode. If you don't plan to use remote control, the SmartDevice feature can be turned off in Settings to save energy.
Through the app, you can receive notifications about an open door, a change in temperature, or the need to defrost. This is especially useful when you're out and about and want to make sure your food is safe. The system can also suggest optimal settings depending on the load on the cameras.
What to do if the phone does not see the refrigerator?
Make sure that your router operates in the 2.4 GHz band (many modules do not support 5 GHz). Also check if your firewall is blocking the connection. Try bringing the phone closer to the front panel of the refrigerator.
Diagnosis of possible startup problems
Even if turned on correctly, situations may arise that require attention. If you hear a loud knocking or vibration immediately after starting, check whether the refrigerator is level and is not touching the walls of the cabinet or furniture. Compressor vibration can be transmitted to the body, increasing the noise.
Sometimes users are faced with a situation where the red alarm indicator is on. This means that the temperature inside the chambers has not yet reached the set values. In the first hours of operation after switching on, this is a normal phenomenon, and the signal should go out on its own after cooling.
If the alarm does not stop for more than 24 hours, the door seal may be damaged or it is not closed tightly. Check to see if anything is preventing the sash from sealing tightly. Also, the cause may be a malfunction of the sensor or a refrigerant leak, which requires calling a technician.
Recommendations for operation on the first day
First 24 hours are critical for the correct temperature balance to develop. During this period, it is not recommended to open doors unnecessarily and load large amounts of warm food. Let the equipment run idle so that it stabilizes the internal climate.
Pay attention to the operation of the system NoFrost or SmartFrost. You may hear periodic clicks or the sound of liquid flowing - this is the refrigerant switching valve or defrost heating element operating. Such sounds are a sign that the complex cooling system is working properly.
After the refrigerator has been running for a day, check the temperature of the food using an external thermometer. The readings must correspond to the values set on the display. If the difference is significant, calibrate or contact the service center.
How long should you wait before loading food?
Complete cooling of an empty refrigerator to the set temperatures takes from 4 to 12 hours, depending on the volume of the chambers and the ambient temperature in the room. It is better to load food after the appliance has worked for at least 6 hours and returns to normal mode.
Why are the side walls of the refrigerator hot?
In modern models Liebherr the capacitor is often built into the side walls of the case. Their heating to 40-50°C in the first hours of operation or during active freezing is the norm and indicates intensive heat removal.
Is it possible to turn on the refrigerator immediately after transportation?
It is strictly not recommended. The oil should drain into the compressor crankcase. If you turn on the device immediately, a water hammer may occur, which will lead to breakdown of the compressor. The minimum settling time is 2 hours, the optimal is 4 hours.
