Buying new household appliances is always a joyful event that promises comfort and freshness of products. However, the euphoria of the purchase often causes owners to make critical mistakes in the very first minutes of use. Improper starting of the compressor or ignoring simple transportation rules can reduce the service life of an expensive unit significantly. It is important to understand that the installation process does not end with unpacking the box.
Modern refrigerators, whether classic models Indesit or smart systems Samsung with inverter motors, require careful attention to the physical laws of thermodynamics and mechanics. Errors during the initial connection often lead to failure of the compressor, depressurization of the circuit, or incorrect operation of the electronics. In this article we will analyze each stage in detail: from the moment the equipment is brought into the apartment to the loading of the first products.
You will find out why settlement time is a critical parameter, how to avoid problems with the electrical network and why you need to check the tilt level of the case. Proper preparation will ensure quiet operation and energy efficiency of the device for many years. Do not rush to turn on the retail fork immediately until you become familiar with the technical nuances.
Transportation and settling time of equipment
The most important stage, which is often ignored in a fit of joy, is the adaptation of equipment to new conditions. If the refrigerator was transported in a horizontal position or simply tilted strongly when being carried into an elevator, oil from the compressor could leak into the refrigerant circulation system. An attempt to start the unit in this condition will lead to water hammer or dry operation of the compressor, which is guaranteed to disable it.
The time required for settling directly depends on the ambient temperature and the position during transportation. In winter, when equipment is brought in from the cold, it is necessary to wait not only for the oil to drain, but also to equalize the temperature of the internal components. A sharp temperature change can cause the formation of condensation on the control board, which will lead to a short circuit when turned on.
- ❄️ When transporting vertically in the warm season, it is enough to let the equipment stand for 2-3 hours.
- 🚚 If the unit was lying horizontally, the minimum waiting time increases to 8-12 hours.
- 🌨️ In winter, after being brought in from the street, the refrigerator must remain warm for at least 24 hours before turning it on.
⚠️ Attention: Do not try to speed up the heating process using heaters or hair dryers. Uniform heating of plastic and metal should occur naturally to avoid deformation of seals and microcracks.
Choice of installation location and ventilation
The correct location of the refrigerator in the kitchen space is the key to its effective operation. During operation, the compressor generates heat, which must be freely removed from the condenser. If the equipment is installed in a niche without gaps or pressed tightly against the wall, heat transfer is disrupted and the motor begins to wear out, trying to compensate for overheating.
It is critically important to ensure free air circulation around the housing. Modern models often have hidden or side radiators, but even then, minimal clearances are required. The distance to the back wall should be at least 5-7 cm, and to the side walls and upper cabinets - at least 10 cm. This will allow air to circulate freely and cool the heating elements. Avoid installing the refrigerator near heat sources such as an oven or radiators. Increased ambient temperature causes the compressor to turn on more often and work longer, which increases energy consumption. If it is impossible to rearrange the equipment, use heat-insulating screens between the refrigerator.

| Parameter | Minimum distance | Consequences of violation |
|---|---|---|
| To the rear wall | 5-7 cm | Condenser overheating, noise |
| Up to side walls | 5-10 cm | Case heating, increased flow rate |
| Top (up to cabinet) | 10-15 cm | Insufficient air draft |
| To the stove/oven | 15-20 cm | Critical overheating of the compressor |
Checking the electrical network and grounding
The refrigerator is an energy-intensive device that is sensitive to voltage changes. An unstable electrical network is one of the main reasons for the failure of compressors and electronic control units. Before connecting, make sure that the socket is working properly, does not spark and holds the plug tightly. The use of extension cords and tees is highly undesirable, as they can become a source of heat and fire.
Particular attention should be paid to grounding. Many modern models, especially those with system No Frost and electronic control, require a grounding loop. Without grounding, static electricity can accumulate on the metal case or a leakage current may occur, which is dangerous for the user and harmful to the electronics of the device.
If your house has old wiring without grounding, it is recommended to install a residual current device (RCD) on the line supplying the kitchen. This device will instantly turn off the power at the slightest current leak, preserving equipment and protecting residents. It is also worth checking the voltage in the network: it should be in the range of 220-230 Volts.
⚠️ Attention: It is strictly forbidden to connect the refrigerator to the same outlet with powerful consumers, such as a microwave oven or electric kettle. A power surge when turning on the second device can damage the compressor.
☑️ Checking the electrical network
Level installation and door adjustment
After the refrigerator has settled and a place has been selected, it is necessary to set it strictly level. Incorrect tilting of the body leads to the fact that the doors no longer close tightly or, conversely, open by themselves. This breaks the seal of the chamber, the compressor works continuously, trying to maintain the set temperature.
To adjust, use a building level, applying it to the top shelf inside the refrigerator or to the upper end of the case. Adjustment is carried out by unscrewing or tightening the front support legs. The correct position is when the front legs are slightly higher than the back legs, creating a slight slope back. This ensures the door closes naturally under the influence of gravity.
If the doors are skewed, check the tightness of the seal around the entire perimeter. In new models, factory deformation of the seal is often found, which can be eliminated by heating it with a hairdryer or simply closing the door tightly for several hours. Also make sure that the shelves are installed level and do not interfere with closing.
- 📏 Use a bubble level to check horizontality.
- 🚪 The door should open to approximately 45 degrees and return to the closed position on its own.
- 🔧 Adjust the legs with the key going to kit, or pliers.
What to do if the door still does not close tightly?
Check if there is anything inside (products, shelves) in the way. If there are no obstructions, the opening side of the door may have been reversed upon delivery and the hinges were not installed correctly. In this case, you will need to reinstall the loops.
First launch and setting temperature conditions
When all the preparatory stages have been completed, you can proceed to the first launch. Plug in the refrigerator and listen: in the first minutes of operation, you can hear the gurgling of refrigerant or the quiet hum of the compressor - these are normal operating sounds. However, an extraneous clang, knock or high-pitched whistle should alert you.
Modern refrigerators are often equipped with electronic controls. After turning on, the display may blink or show the current temperature in the chamber, which is still high. Take your time loading products. Let the unit run idle for at least 2-4 hours so that it reaches operating temperature conditions and the automation records the on-off cycles.
Adjust the temperature conditions according to the instructions. For the main compartment, the optimal temperature is +2...+4°C, for the freezer - -18°C and below. Do not immediately set the minimum values unless absolutely necessary, as this will increase the time of the first cooling cycle.
Critical important: when first starting, do not completely fill the refrigerator with food. Loading warm products will disrupt the temperature balance and force the compressor to work in extreme mode.Typical connection errors
Even following the instructions, users often make mistakes that can cost warranty or repair. One of the most common is ignoring the operating instructions for a particular brand. For example, some models LG or Bosch have specific requirements for transporting the compressor, which differ from the general rules.
Another mistake is the use of household chemicals to remove the factory film and odor immediately after installation. Aggressive solvents can damage plastic and rubber seals. It is better to use a weak soda solution or special products for household appliances.
Also, do not forget about checking the system No Frost. If after the first cycle of operation ice or a “fur coat” forms on the back wall of the main chamber, this may indicate a malfunction or incorrect installation. In this case, it is better to call a warranty technician without waiting for the problem to worsen.
- 🚫 Starting earlier than the recommended settling time.
- 🔌 Connection through cheap low-quality surge protectors.
- 🌡️ Setting the temperature too low in the first hours work.
⚠️ Attention: If you notice a burning or plastic smell when you first turn it on, immediately unplug the device. This may be burnout of the factory lubricant (normal in small quantities) or a wiring defect (dangerous).
Why can the refrigerator hum loudly after installation?
A loud hum is often associated with improper level installation or touching the condenser tubes to the wall or cabinet. Also, the reason may be transportation bolts if they have not been removed (relevant for some models with suspended compressors).
Frequently asked questions (FAQ)
Is it possible to immediately load food into a new refrigerator?
No, it is absolutely not recommended. The refrigerator must run empty for at least 2-4 hours to reach operating temperature. Loading warm products will create excess load on the compressor and can lead to food spoilage due to long cooling.
What to do if the refrigerator was transported lying down?
If the refrigerator was lying down, oil could leak into the cooling circuit. It is necessary to let it stand in a vertical position for at least 8-12 hours (preferably a day) before turning it on. This will allow the oil to drain back into the compressor.
Do you need to wash the refrigerator before first use?
Yes, definitely. Factory dust or the smell of plastic or packaging may remain inside. Wipe the internal surfaces with a soft cloth soaked in a weak solution of soda or a special product and let dry.
Why do the side walls of the refrigerator heat up?
This is normal for many modern models. Condenser tubes are often mounted in the side walls, which release heat. The main thing is that the heating is uniform and not scalding, and that clearances for ventilation are maintained.
Is it possible to connect a refrigerator via an extension cord?
Manufacturers do not recommend using extension cords. If you cannot do without them, use only high-quality surge protectors with grounding and a wire cross-section corresponding to the power of the device. Twists and cheap extension cords are prohibited.
