Initial launch of a new one Installing a refrigerator is not just plugging into a socket, but a complex process that requires compliance with time and technical regulations. If you have just unpacked the series unit Liebherr Premium, you will have to perform a number of preparatory steps that will ensure the durability of the compressor and the safety of the products. Ignoring the rules for adapting equipment to room temperature can lead to irreversible damage to the cooling system.
Modern models of the German brand are equipped with complex electronics that require correct initialization after transportation. Unlike old mechanical devices, it is important here not only to wait for the oil to melt, but also to correctly activate SmartSteel or SmartFrost systems. Let's look at how to prepare your device for operation without risking expensive equipment.
The very first thing you need to do is let the equipment settle. The waiting time directly depends on the transportation conditions: if the refrigerator was transported in a vertical position, 2-3 hours are enough, while horizontal transportation requires up to 12 hours. This is necessary in order to compressor oil glass back into the engine crankcase.
⚠️ Attention: An attempt to turn on the compressor immediately after horizontal transportation can lead to water hammer, since oil will enter the refrigerant circuit, which is almost guaranteed to damage the unit.
After the equipment has been left in a warm room, it is necessary to conduct a visual inspection and remove all shipping elements. Pay special attention to the interior and back wall, where fixing tapes or foam inserts are often hidden. Only after complete removal of the packaging can you begin placement.
Installation of the refrigerator Liebherr requires compliance with strict ventilation rules. Air must circulate freely around the housing, especially in the area of the heat exchanger, which in modern models is often hidden in the side walls. The minimum distance to walls and furniture should be at least 5-7 cm at the back and sides.
If you plan to integrate appliances into a kitchen set, make sure that there are special ventilation grilles in the base and upper part of the niche. Lack of cold air flow will lead to overheating of the compressor and increased energy consumption. Correct heat exchange is the key to quiet operation and saving electricity.
When the location has been chosen and the equipment has survived, you can begin the actual launch. The first step is to connect to the power grid. Please note that Liebherr Premium is sensitive to voltage surges, so using a high-quality surge protector or stabilizer would be a reasonable precaution.
After connecting to the outlet, the indicators on the control panel will light up, indicating that power is supplied. At this moment, do not rush to load the products - the refrigerator requires time to reach the set temperature. This process usually takes from 4 to 8 hours depending on the volume of the chamber and the ambient temperature in the room.
It is important to ensure that the doors are tightly closed during the initial cooling. If you hear a characteristic gurgling or hissing sound, do not be alarmed, this is the refrigerant starting to circulate. Such sounds are normal for modern environmentally friendly cooling systems and do not indicate a malfunction. R600a. Such sounds are normal for modern environmentally friendly cooling systems and do not indicate a malfunction.
Setting temperature conditions is a critical step on which the shelf life of products depends. For the refrigerator compartment, the optimal value is considered to be between +3°C and +5°C, while for the freezer compartment the standard is -18°C. Series models Premium often have separate cooling circuits NoFrostthat allow you to set parameters independently.
For precise adjustment, use the touch panel or rotary control, depending on the specific modification. On digital models, changing the value by one degree may take several seconds - wait until the signal is confirmed. You should not immediately set extremely low temperatures, this will create an extra load on the system.
Particular attention should be paid to the function SuperCool (Super cooling). This mode allows you to quickly cool a large amount of food by temporarily reducing the temperature in the chamber. It is worth activating it several hours before loading products, and after filling the chamber, do not forget to turn it off to avoid freezing.
⚠️ Attention: Long-term operation in SuperCool mode without loading warm products will lead to the formation of excessive ice on the evaporator and an increase in energy consumption.
In the freezer compartment the SuperFrostmode works in the same way. It is necessary for initial freezing or loading of large volumes of fresh products. The system will automatically turn off after a certain time or after reaching the specified parameters, however, some models require manual disabling of the function.
☑️ Check before loading products
Modern refrigerators Liebherr are equipped with a self-diagnosis system that displays error codes or warning signals on the display. If you see a flashing light or hear an intermittent beep, this may indicate that the door is not closed tightly or the temperature inside is too high.
A common mistake made by users is to ignore the "Open Door" signal. If the refrigerator cannot seal the circuit within 60 seconds, it will sound an audible warning. Make sure that the products do not interfere with the tight fit of the seal, and that the seal itself is clean and free of damage. The seal is also worth checking the operation of the system (if it is provided by the model). This technology reduces ice formation but requires proper initial setup. If you notice that ice is still growing faster than usual, the seal may be broken or the defrost sensor is faulty. seal clean and undamaged.
It is also worth checking the operation of the system SmartFrost (if provided by the model). This technology reduces ice formation but requires proper initial setup. If you notice that ice is still growing faster than usual, the seal may be broken or the defrost sensor may be faulty.
| Parameter | Recommended value | Acceptable range | Impact on products |
|---|---|---|---|
| Refrigerator compartment temperature | +4°C | +2°C ... +6°C | Optimal for meat, dairy products |
| Freezer temperature | -18°C | -16°C ... -24°C | Long-term storage without loss of properties |
| BioFresh zone (zero) | 0°C ... +2°C | Strictly according to the sensor | Fresh vegetables, fruits, fish |
| Holding time after transportation | 4-12 hours | Depends on the tilt | Saving compressor |
What do the flashing indicators mean?
If the temperature symbol is flashing, it means that the current value is higher than the set value. This is normal during the first hours of operation or after loading warm products. If the lock symbol is flashing, child protection is activated.
After the refrigerator has entered operating mode, it is recommended to carry out an initial loading with food. However, this must be done gradually. You should not immediately fill an empty, just turned on unit with a full volume of room temperature products - this will create a critical load on the compressor.
Distribute the products evenly, without blocking the ventilation holes inside the chambers. Air should circulate freely between the shelves. For models with the system VarioSpace you can easily rearrange the shelves to place large items, but it is better to do this before it is fully loaded.
Pay attention to the storage areas: it is better to place meat and fish on the coldest shelves (usually the lower ones or in the BioFresh zone), and vegetables and fruits in special drawers with controlled humidity. Correct zoning will extend the freshness of products several times.
⚠️ Attention: Technical characteristics and location of controls may vary depending on the specific model and year of manufacture. Always check the official instructions included with your device.
Regular maintenance begins from the moment you turn it on for the first time. Make sure that there is no dust accumulating on the rear grille and that there are no foreign odors inside the chambers. Modern filters AirClean effectively eliminate odors, but require periodic replacement or activation.
If you are planning a long absence, you can switch the refrigerator to economy mode or turn off only the refrigerator compartment, leaving the freezer running. This function is available in many models Liebherr Premium through the settings menu.
The correct start of operation is 90% of success in the further operation of the equipment. Following simple rules of exposure, temperature settings and load distribution will allow your refrigerator to serve for decades without repairs or replacement of components.
Is it possible to place a refrigerator on a heated floor?
Technically it is possible, but this will increase energy consumption. It is recommended to use a thermal insulating underlay between the floor and the device to prevent heat transfer through the bottom.
How long can you not turn on a Liebherr refrigerator after delivery?
If the refrigerator was transported in an upright position, it is enough to wait 2-3 hours. If it was lying on its side, it is necessary to pause for at least 8-12 hours to allow the oil to drain into the compressor. The exact time is often indicated on the transport sticker.
Why does the refrigerator make a loud noise immediately after turning on?
In the first minutes of operation, the compressor may operate at high speeds to quickly cool the chambers. There may also be noise from the circulating refrigerant. If the loud hum does not subside after a few hours or is accompanied by vibration, check the level of the feet.
Do you need to wash the inside of the refrigerator before using it for the first time?
Yes, definitely. Wipe the interior surfaces with a soft cloth soaked in a weak soda solution to remove the smell of new plastic and factory dust. After this, wipe the chambers dry and leave the doors open for 30 minutes to ventilate.
What to do if the red alarm indicator is on?
The red indicator signals that the temperature in the freezer has risen above a safe threshold. Check if the door is closed tightly and if you have loaded a lot of warm food. If the indicator does not go out after entering the mode, contact service.
