After transporting and installing the kitchen set, the moment of truth comes - the first start-up of the equipment. Built-in Liebherr refrigerator requires compliance with certain rules before connecting to the mains, so that the compressor reaches operating mode without overload. Ignoring simple steps can lead to a shortened service life of the unit or incorrect cooling in the first hours of operation.
Modern models of the German brand are equipped with sophisticated electronics and innovative freshness preservation systems, such as Liebherr BioFresh. Proper activation of these systems directly affects how long foods remain healthy. In this article we will analyze the entire process from unpacking to setting the exact temperature conditions.
It is important to understand that the activation procedure may vary slightly depending on the series of the device and the year of manufacture. Be sure to let the equipment stand upright for a minimum 4 hours after transportation, so that the oil in the compressor flows into the crankcase. This is a critical step that cannot be skipped if the refrigerator was transported lying down or tilted strongly.
Preparing for the first start and checking the installation
Before pressing the power button, you need to make sure that the installation is correct. Built-in appliances Liebherr are sensitive to overheating, so the presence of ventilation gaps in the cabinet niche plays a decisive role. Check that the base grille is not clogged with construction dust and provides air flow to the condenser.
Make sure that the device is level. Adjusting the legs allows you to compensate for uneven floors, which is necessary for proper closing of the doors and operation of the system NoFrost. If the door is skewed, the seal may not fit tightly, which will lead to the formation of ice.
- 🔌 Check the integrity of the power cord and the absence of visible damage to the insulation.
- 📏 Make sure that the necessary gaps are left around the body for air circulation according to the instructions.
- 🧼 Wipe the internal chambers with a damp cloth and neutral detergent to remove factory dust.
⚠️ Attention: Do not connect the device to the network through an extension cord or tee. Use only a separate outlet with grounding to avoid overheating of the wiring.
The procedure for activating the power and control panel
The activation process depends on the type of control of your model. In modern built-in refrigerators Liebherr there are touch panels SmartTouch, mechanical rotary switches or push-button interfaces. Electronically controlled devices often require activation via the “On/Off” or “Power” button, which must be held for several seconds.
If the symbols light up on the display, but the temperatures are not yet displayed, it means that the system is undergoing a self-diagnosis process. The electronics checks the sensors and the health of the fans. At this time, the compressor may not start immediately - this is normal behavior of the smart control system.
In models with a mechanical regulator inside the chamber (usually a rotary knob with numbers from 1 to 5 or from Min to Max), switching on occurs automatically when voltage is applied. Here it is important to immediately set the middle position, for example, number 3, so as not to overload the motor at start.
☑️ Initial start-up
Setting up temperature modes and functions
After a successful launch, the setup phase begins. For the refrigerator compartment, the optimal temperature is considered to be from +4°C to +5°C. The freezer must be set to -18°C for long-term food storage. Make fine adjustments using the "+" and "-" buttons on the control panel.
The activation of the freshness zone deserves special attention. BioFresh. This technology maintains temperatures around 0°C and high humidity, which is ideal for vegetables, fruits, meat and fish. This function is activated using a separate button or through the menu, depending on the interface of your model.
Some models are equipped with a mode SmartFrost or a quick freezing function FrostMatic. These options are useful when initially loading a large number of products. Activate them in advance so that the camera quickly reaches the desired temperature mode.
| Camera | Recommended t°C | Function | Purpose |
|---|---|---|---|
| Refrigeration | +4...+5°C | SuperCool | Quick cooling of drinks |
| Freezer | -18°C | FrostMatic | Blast freezing of food |
| BioFresh | 0...+2°C | HydroBreeze | Preservation of vitamins in fruits |
| VarioZone | Flexible | FlexiUse | Transformation of space |
What is Vacation mode?
Vacation mode switches the refrigerator compartment to an economical operating mode with a temperature of about +14°C, preventing the appearance of mold and odor while the freezer continues to operate in normal mode.
Time to enter operating mode and loading with products
Do not rush to fill the shelves immediately after switching on. An empty refrigerator Liebherr needs 2 to 6 hours to stabilize the temperature in all zones. The exact time depends on the volume of the chambers, the ambient temperature in the room and the compressor model.
Loading with warm products immediately after switching on will force the compressor to work at its limit, which can lead to protection or breakdown. Wait until the temperature indicators stop flashing on the display and the set values are recorded.
- 🥩 Place meat and fish in the BioFresh zone or on the bottom shelf of the main chamber.
- 🥛 It is better to store dairy products on the middle shelves, where the temperature is most stable.
- 🍺 Drinks can be placed on the door, but do not store foods that require strict temperature control there.
⚠️ Attention: If you load a lot of food at once, turn on the Super Freeze or Super Cool mode a few hours beforehand.
Diagnostics of possible problems when turning on
Sometimes after turning on the user may encounter non-standard behavior of the equipment. For example, a loud sound is heard or the emergency indicator lights up. This often indicates that the door is not closed tightly or the temperature inside has not yet reached the set parameters.
If the refrigerator hums too loudly, check that all shipping bolts have been removed (if your model had them) and that the body is level. Vibration can be transmitted to the furniture frame, increasing the noise. Also make sure that the tubes and wires do not touch the compressor from the back.
If an error code appears on the display (for example, F or E with a number), refer to the instructions. Often the codes indicate problems with the temperature sensors or defrost system. Self-repair of electronics without qualifications may lead to loss of warranty.
Frequently asked questions (FAQ)
Why does the Liebherr refrigerator not turn on immediately after connecting to socket?
Modern models have a compressor start delay to protect the electrical network. Also check that the door is closed tightly and that the power light is on. If after 15 minutes there is no work, check for voltage in the socket.
How long can you not open the refrigerator after turning it on for the first time?
It is advisable not to open the doors during the first 2-3 hours of operation. This will allow the unit to gain cold faster without heat flow from outside. Complete stabilization of the food temperature takes up to 24 hours.
What to do if the red alarm indicator is on?
The red indicator signals an increase in the temperature in the chamber. Make sure that the door is tightly closed, the Holiday mode is turned off and enough time has passed since it was turned on. If the indicator does not go out after a day, call a technician.
Is it possible to turn on a Liebherr refrigerator in an unheated room?
Most household models are designed to operate in climate class SN-T (from +10°C to +43°C). Operation at temperatures below +10°C can lead to oil freezing in the compressor and failure. Special models are needed for garages.
