Buying a new refrigerator is always a joyful event, marking the beginning of a comfortable life, but it is in the first hours of operation that the foundation for the durability of the unit is laid. Many owners make the fatal mistake of plugging in equipment immediately after delivery, not knowing about the hidden risks that can lead to breakdown of an expensive compressor. Correct initial installation requires patience and adherence to a clear algorithm of actions, ignoring which often becomes the reason for refusal of warranty service. Modern models are complex engineering systems that are sensitive to transport influences and temperature changes. In order for your
Modern models Liebherr, Bosch or Indesit They are complex engineering systems that are sensitive to transport influences and temperature changes. To your refrigerator to serve properly for many years, it is necessary to competently carry out preparatory work, which includes acclimatization, removal of preservation materials and initial start-up without load. In this article, we will analyze each stage in detail so that you can avoid common mistakes.
Transportation and acclimatization time of equipment
The first and most critical stage is the time interval after delivery of the device to the premises. The fact is that during transportation, especially if the refrigerator was tilted at an angle of more than 40 degrees, oil from the compressor could flow into the refrigerant circulation circuits. If you turn on the unit immediately, the compressor will work “dry,” which will lead to its rapid failure or water hammer.
Settling time directly depends on transportation conditions and ambient temperature. If the device was transported in an upright position, it is enough to let it stand for 2-3 hours. However, during horizontal transportation or a strong tilt, this period must be increased to 8-12 hours, and in winter, when the equipment has come from frost to heat, experts recommend waiting up to 24 hours for complete warming up and evaporation of condensation inside the electronics.
You should not rush to connect, even if visually the device seems ready for use. Condensation, formed on the internal elements due to a sharp temperature change, must completely evaporate so as not to cause a short circuit. This is especially true for models with a system No Frost, where electronic control boards are located in close proximity to the evaporators.
⚠️ Attention: If you brought the refrigerator in the cold in winter, do not unpack it immediately in a warm room. Let the package sit in the hallway or stairwell for 30-40 minutes to avoid moisture forming inside the case due to warm air condensing on cold surfaces.
It is also important to consider that different manufacturers may give their own recommendations on this matter. For example, some brands indicate specific requirements for their compressor models. Always check the documentation, as User's Manual specific requirements for your compressor models. Always check the documentation as the minimum settling time for inverter compressors is often at least 4 hoursregardless of the transport position.
Removing packaging and preparing the internal space
After the device has settled, it is necessary to carefully remove it from the transport protection. Inside the chamber there are often foam inserts, paper pads and plastic bags that protected shelves and drawers during delivery. All these elements must be removed, since they not only occupy useful volume, but can also block air circulation.
Particular attention should be paid to the fixing elements. Some models have special shipping bolts or tape that hold doors and interior shelves in place. Forgetting to remove the securing tape from the drawers or not removing the spacers between the walls can lead to deformation of the plastic or failure of the doors to close tightly in the future.
- 📦 Remove all external films, tape and cardboard corners from the body.
- 🧼 Remove all shelves, drawers and containers for a thorough washing.
- 🔍 Check the presence of small parts in the packaging bags (for example, egg trays or keys for adjusting the legs).
- 🚫 Make sure that there are no foreign objects or fasteners left inside.
Cleaning the internal surfaces is a mandatory procedure before first use. Even if the refrigerator looks clean, there may be traces of factory grease, dust, or a new smell on the plastic and metal. To wash, use warm water with the addition of a mild detergent or baking soda solution, avoiding aggressive chemicals and abrasive sponges.
☑️ Primary processing of the refrigerator
After washing, all removable elements must be wiped dry and installed in their places according to the diagram in the instructions. Make sure the shelves are level and locked in place and that the vegetable drawers move freely without getting stuck in the guides. Only after complete assembly can you proceed to the next stage.
Selecting an installation location and leveling the case
The correct location of the refrigerator affects its operating efficiency and level of energy consumption. The unit should not be placed close to a wall or furniture, since the condenser (grid at the back) requires free air flow to operate. The minimum distance to the back wall should be at least 5-7 cm, and on the sides - 5 cm.
A critically important point is the horizontal alignment of the case. Uneven installation causes the doors to skew, which can cause them to fit loosely or open spontaneously. In addition, vibration from an incorrectly installed compressor will be transmitted to the floor and furniture, creating annoying noise.
For adjustment, use the front support legs, which can usually be twisted or unscrewed. By rotating them, achieve a position so that the refrigerator is stable and does not wobble when pressed lightly. Many models also have the function of tilting the body slightly back so that the doors close themselves under the influence of gravity.
Do not place the refrigerator in close proximity to heating appliances such as radiators, ovens or stoves. You should also avoid direct sunlight on the housing, as this forces the compressor to work with increased load, trying to compensate for external heating.
First switching on and checking the operation of the compressor
After completing all the preparatory work, you can move on to the most crucial moment - the first switching on to the electrical network. It is recommended to use a separate grounded outlet, avoiding the use of extension cords or low-quality surge protectors that may not withstand inrush currents.
When starting up for the first time, do not load the refrigerator with food. Let it run idle for 5-8 hours. During this time, the unit should reach the required temperature in the chambers, and you will be able to assess the noise level and the absence of extraneous sounds. The hum of the compressor, the gurgling of the refrigerant and the periodic clicking of the relay are considered normal.
Pay attention to the operation of the system No Frost (if there is one). In idle mode, you may hear the sound of a running fan or a crackling noise caused by thermal expansion of the plastic - these are normal phenomena. However, a piercing whistle, knocking or vibration radiating to the floor requires immediate shutdown and contacting service.
| Check parameter | Normal state | Alarm signal |
|---|---|---|
| Operation sound | Uniform humming, quiet gurgling | Loud knocking, clanging, squealing |
| Heating of the side walls | Warm to the touch (the circuit is working) | Very hot or completely cold |
| Vibration of the body | Barely noticeable or absent | Severe trembling, movement from place |
| Cooling | The appearance of cold after 30-60 min | No cold after 2 hours |
During the primary cooling process, check the tightness of the doors. To do this, you can clamp a sheet of paper between the seal and the body: it should be removed with noticeable force along the entire length of the perimeter. If the paper slides freely, it means the door is warped or the seal is damaged.
Setting the temperature mode
Modern refrigerators allow you to flexibly adjust the climate inside the chambers. After the device has run idle and reached base temperatures, you can set the optimal values. For the main compartment, the standard recommendation is a range from +3 to +5 degrees Celsius.
Control can be carried out by a mechanical regulator (knob with numbers from 1 to 7) or an electronic display. Remember that on mechanical regulators the number does not indicate degrees, but the cooling power: the higher the number, the colder it is. The optimal middle position is usually a value of 3 or 4.
It is recommended to set the temperature in the freezer to -18 degrees. This value is considered the “gold standard” for long-term food storage, since at this temperature the growth of bacteria stops and the beneficial properties of food are preserved. Lower temperatures (-24°C) are needed only for the fast freezing function.
What is the freshness zone?
The freshness zone (zero chamber) is a special compartment where the temperature is maintained at about 0°C and high humidity. Ideal for storing meat, fish, cheeses and herbs, extending their shelf life by 2-3 times compared to a regular shelf.
If your model has a function Eco Mode or “Vacation”, read the instructions before activating. These modes change the algorithm of the compressor to save energy, but may not be suitable for storing perishable products in large volumes immediately after purchase.
Loading with products: rules and restrictions
After a successful test run, you can begin loading the refrigerator with products. This should be done gradually, without filling all the shelves at once to capacity. A sharp change in the thermal balance can force the compressor to work in increased mode, which is undesirable in the first days of operation.
Distribute food correctly: prepared meals and dairy products - on the middle shelves, meat and fish (in airtight containers) - on the lower shelves, and fruits and vegetables - in special drawers below. Do not place hot or warm foods inside, as this will disrupt the temperature regime and increase energy consumption.
- 🥛 Place dairy products closer to the back wall, where it is colder.
- 🥩 Store raw meat only in closed containers on the bottom shelf.
- 🍅 Vegetables and place fruits in the lower drawers, after drying them.
- 🚫 Do not overcrowd the refrigerator, air should circulate freely.
⚠️ Attention: Do not fill the freezer with a large amount of room temperature food on the first day. It is better to freeze in small portions using the “Super Freeze” mode, if it is provided for in the design.
Following the loading rules will not only extend the life of the equipment, but will also ensure the best quality of storage of your products. Uniform weight distribution is also important for the stability of shelves, especially glass ones, which can crack under uneven load.
Frequently asked questions when starting up for the first time
Is it possible to plug in the refrigerator immediately after delivery if it has not been tilted?
Even if the refrigerator was transported strictly vertically, manufacturers still recommend waiting at least 2-3 hours. This is necessary to stabilize the pressure in the system and adapt the electronic components to room temperature, especially if delivery was carried out during the cold season.
Why do the side walls of the refrigerator get very hot when you first turn it on?
Heating of the side walls (up to 40-50 degrees) in the first hours of operation is an absolutely normal process. In modern models, the condenser (heat exchanger) is often built into the side walls of the case. Active heat generation indicates that the cooling system is working correctly and removing heat from the chambers.
How long does it take the refrigerator to reach temperature for the first time?
The time it takes to reach operating mode depends on the volume of the chambers and the temperature in the room. Typically it takes 4 to 8 hours to reach stable temperatures. Complete stabilization of the thermal regime and the formation of a “cold reserve” can take up to 24 hours.
Do you need to wash the inside of a new refrigerator before use?
Absolutely. Inside the new refrigerator there may be industrial dust, a plastic smell, or traces of factory grease. Wiping with a damp cloth with a mild detergent or soda solution will remove these contaminants and ensure hygienic food storage.
