Buying a new refrigerator is always a joyful event, marking an update of kitchen appliances and improved storage conditions for food. However, the joy can be overshadowed if you ignore the basic rules for transporting and initial installation of the unit. Incorrect actions in the first hours after delivery can lead to serious damage to the compressor, a violation of the system's tightness, or a reduction in the service life of the device.
Many owners make the mistake of believing that it is enough to simply take the box into the kitchen, cut the tape and plug the plug into the socket. In fact, the process of how to properly install and connect a refrigerator requires compliance with time intervals, temperature conditions and geometric accuracy. Ignoring these nuances often becomes the reason that the equipment stops freezing after just a few months of operation.
In this article we will analyze in detail all the stages: from acclimatizing the device to fine-tuning the legs and checking the tightness. You will learn why you should not turn on the device immediately after winter delivery and how to ensure stable operation of the motor for many years. Compliance with these rules is the key to ensuring that your products will always be fresh, and your equipment will not require expensive repairs.
Acclimatization and exposure before the first start
The most critical point that most users forget about is the exposure time. If the refrigerator was delivered in the warm season, it needs to stand in an upright position for at least 2-3 hours. This is necessary in order to stabilize the temperature of the internal components and evaporate condensation that could form on the electrical contacts.
The situation changes dramatically if delivery was carried out in winter or in the off-season at low temperatures. In this case holding time increases to 4-6 hours, and ideally - up to a day. A sharp temperature change when turning on the compressor can lead to thermal shock of metal and plastic, as well as damage to the motor winding.
⚠️ Attention: If the refrigerator was transported lying down (which is extremely undesirable, but sometimes necessary), the settling time should be at least 8-10 hours. The oil must completely drain into the compressor crankcase, otherwise water hammer will occur.
Particular attention should be paid to models with the system No Frost. They have a lot of plastic elements and fans, which should also reach room temperature. An attempt to start the fan while the plastic is still “oak” can lead to its deformation or cracks.
Why does oil get into the cooling system?
When transported in a horizontal position, oil from the compressor flows into the cooling circuit. If you turn on the unit right away, the compressor will try to compress the liquid (oil), which will lead to valve failure or jamming of the piston group.
Selecting a location and preparing the surface
Before unpacking the unit, it is necessary to determine a permanent location for it. Correct installation of the refrigerator is impossible without taking into account ventilation requirements. During operation, the compressor generates heat, which must be effectively removed. If you place the equipment close to the wall or in a niche without an air gap, the motor will wear out.
The distance from the back wall of the refrigerator to the wall should be at least 5-7 centimeters. It is also advisable to leave gaps of 2-3 centimeters on the sides for air circulation. It is strictly forbidden to install the refrigerator next to: a gas stove, oven or heating radiators. The increased ambient temperature forces the compressor to work almost without stopping.
The floor surface should be smooth and hard. If the floor is covered with soft linoleum or carpet, it is recommended to place hard plywood or plastic plates under the legs of the refrigerator. This will prevent the coating from being pressed through and ensure stability.
Unpacking and removing shipping fasteners
After the equipment has settled, you can begin unpacking. Remove the cardboard box, top foam and protective film. Pay special attention to the inside: often manufacturers fix shelves, drawers and doors with tape or foam inserts so that they do not break during transportation.
All shipping bolts and fasteners must be removed. In some models, the compressor may be secured with special bolts from the bottom or rear (although this is less common in modern household models). If these fasteners are not removed, vibration during engine operation will destroy the fastenings.
- 📦 Remove all packaging material, including tape from the internal shelves.
- 🔩 Check for and remove shipping bolts on the compressor (if provided design).
- 🧼 Wipe the internal surfaces with a damp cloth with the addition of a weak soda solution to remove the factory smell.
- 🚪 Make sure that the doors open freely and nothing interferes with their movement.
After cleaning, leave the doors open for another 30-60 minutes. This will allow the technical odors of plastic and polyurethane foam to completely disappear. Only after this can you begin installation.
Aligning and adjusting the legs
One of the most important stages is horizontal installation. Incorrect tilting of the housing may result in the door not fitting tightly or, conversely, opening by itself. In addition, misalignment causes uneven load on the compressor and increased noise.
Use a building level to check the horizon. Adjustment is carried out using the front support legs, which can be twisted or unscrewed. The rear legs are usually non-adjustable. Achieve such a position that the bubbles of the level are strictly in the center.
☑️ Checking the level installation
There is an important nuance: many manufacturers recommend installing the refrigerator with a slight tilt back (about 2 degrees). This is necessary so that the door closes itself when opened less than 90 degrees, ensuring tightness. If you place the unit strictly level or tilted forward, the door will have to be slammed shut with force.
⚠️ Attention: Do not leave the refrigerator standing only on the front adjustable legs without support on the rear wheels or thrust bearings. This creates excess voltage in the lower frame of the case.
Connecting to the electrical network
Electrical safety is priority number one. The refrigerator is an energy-intensive appliance with an electric motor, so the wiring requirements are strict. The connection should only be made into a working outlet with grounding.
The use of various extension cords, tees and adapters is strictly prohibited, especially if they are of poor quality. Poor contact at the junction of the plug and socket leads to heating and melting of the plastic, which can cause a fire. If the outlet is far away, it is better to replace the wiring or move the connection point.
| Parameter | Requirement | Consequences of violation |
|---|---|---|
| Voltage | 220-230 V (±10%) | Electronics burnout or startup failure |
| Grounding | Required | Risk of electric shock if a breakdown occurs on the body |
| Socket type | With a grounding contact | Heating of contacts, fire hazard |
| Separate line | Recommended | Knocking out plugs during inrush currents |
If power surges often occur in your home, it is recommended to install a voltage stabilizer. The electronics of modern refrigerators, especially models with displays and systems Smart Home, are very sensitive to changes in the network.
First launch and performance check
After all preparation steps are completed, you can turn on the refrigerator. When starting for the first time, do not load food inside. Let the unit run idle for at least 2-3 hours (or better yet, leave it overnight). During this time, it should reach operating temperature.
Pay attention to the sound of the compressor running. A slight hum and periodic gurgling of the refrigerant in the tubes is allowed. However, sharp knocks, grinding or ringing of metal indicate a malfunction or incorrect installation (tubes touching the body or cabinet walls).
Check the operation of the defrosting system (if it is No Frost). After some time after switching on, large ice build-ups should not form on the back wall of the main chamber. There should also be no excess frost in the freezer.
Frequent installation errors
Even knowing the theory, people manage to make typical mistakes that nullify all efforts. One of the most common is installing a refrigerator in a niche of a kitchen unit “butt-to-wall”. Lack of ventilation leads to the fact that heat is not removed, and after a year or two the compressor fails.
Another mistake is ignoring the floor level. If the refrigerator is positioned crookedly, the oil in the compressor may flow into the cooling circuit, causing the capillary tube to clog. Also, curvature leads to skewed doors and a violation of the tightness of the seal.
- 🚫 Installation next to a battery or stove without a heat-insulating screen.
- 🚫 Using damaged or old wiring without grounding.
- 🚫 Loading with products immediately after switching on (violates the temperature regime).
- 🚫 Ignoring the instructions on the minimum distances from the walls.
⚠️ Attention: Never try to add freon yourself or rehang the doors if you do not have the skills of a master. This may lead to loss of warranty and refrigerant leakage.
Following all recommendations will allow your refrigerator to serve faithfully for many years. Correct installation is the foundation for reliable operation of the equipment.
What to do if the refrigerator vibrates a lot?
Check whether the tubes at the back of the cabinet or walls are touching. Make sure all feet are firmly planted on the floor. Sometimes vibration is transmitted from poorly secured shelves inside - correct them.
Is it possible to place a refrigerator on a glazed balcony?
It is strictly not recommended. On the balcony, the temperature often drops below +10°C or rises above +30°C, which disrupts the operation of the compressor and leads to solidification of the oil. In addition, direct sunlight destroys plastic and rubber seals.
How long after switching on can you load food?
The optimal time is after 2-3 hours of idle operation. During this time, the cameras will have time to cool to the set temperatures. If you load warm food at once, the compressor will work without stopping, trying to cool a large volume, which is harmful for it.
Why does the refrigerator make gurgling sounds?
This is a normal phenomenon caused by the circulation of refrigerant (freon) through the system pipes. In modern models with the system No Frost the sound of a running fan can also be heard. You should only worry if the sound changes to a loud knocking or grinding sound.
Do you need to wash the refrigerator before using it for the first time?
Yes, definitely. Factory dust and the smell of plastic and packaging may remain inside. Wipe all surfaces with a soft cloth soaked in a weak soda solution or a special refrigerator cleaner, then wipe dry.
What to do if the plug does not fit into the outlet?
Do not use adapters or cut off the grounding contact under any circumstances. The best solution is to replace the outlet with a suitable grounded one. If this is not possible, call an electrician to correctly solve the problem, since this is a matter of safety.
