Buying new household appliances is always accompanied by joy, but also by a certain amount of anxiety, especially when it comes to large-sized equipment. Immediately after delivery, many owners make the mistake of trying to fill the shelves with products and put the unit into operation as quickly as possible, but rushing in this matter is unacceptable. Incorrect actions in the first hours of operation can significantly reduce the life of the compressor and disrupt the operation of the cooling system, which will lead to expensive repairs.
There are several critically important nuances, ignoring which often causes the failure of modern equipment. In this article, we will look in detail at how to properly prepare the unit for work, how long you need to wait after transportation, and what stages a competent one includes first launch. Following simple rules will help you avoid common mistakes and ensure a long life for your new assistant.
First of all, it is worth understanding that the logistics of household appliances often involves tilting them or even turning them over, which is strictly prohibited in working condition. Oil from the compressor can leak into the refrigerant circuit, and if you turn on the device immediately, water hammer can damage the expensive unit. Therefore, before connecting the cord to the outlet, it is necessary to carry out a number of preparatory procedures.
Adaptation of equipment after transportation
Transporting a refrigerator, especially in winter or over long distances, is a serious stress for its internal mechanisms. Vibration, shaking and changes in the position of the housing lead to displacement of oil in the compressor, which enters the evaporator and condenser tube system. If you apply power to the engine at this moment, it will operate in oil starvation mode, and the coolant itself, mixed with oil, can clog thin capillaries.
The time required for acclimatization directly depends on how exactly the unit was transported. If the equipment was transported strictly in an upright position, without strong shaking or tilting, then the minimum settling time is about 2-3 hours. This is enough for the oil to flow back into the compressor crankcase, and for the electronics to stabilize after temperature changes.
⚠️ Attention: If the refrigerator was transported lying down or at a strong slope, the waiting time should be increased to 12-24 hours. In winter, it is also recommended to extend this period, since oil that has thickened in the cold takes more time to return to its original state and warm up to room temperature.
In addition, if the equipment came into the room from the cold, you should not rush to turn it on. A sharp temperature change will cause condensation to form on the internal and external elements of the case, as well as on electrical contacts. Moisture inside the electrical circuit can cause a short circuit during the first start-up.
You should also not forget about the external inspection. While the equipment is "resting", carefully check the body for dents, paint chips or damage to the door seals. Any defects discovered after delivery must be recorded with the courier service until the acceptance certificate is signed.
Choosing the right place for installation
The correct location of the refrigerator is not only a matter of aesthetics, but also a necessary condition for the effective operation of the cooling system. During operation, the engine generates heat, which must be freely dissipated into the environment. If you leave minimal gaps between the walls of the unit and the furniture, the compressor will work hard, trying to maintain the set temperature.
Modern models are often equipped with a system No Frostthat requires good air circulation. The minimum distance from the back wall to the wall should be at least 5-7 cm, and it is advisable to leave at least 2-3 cm of free space on the sides. Some manufacturers indicate more stringent requirements in the technical data sheet, so checking the documentation will not be superfluous.
It is strictly not recommended to install the refrigerator in close proximity to heating devices. Heating radiators, gas stoves or ovens create local areas of elevated temperature, which confuses the sensors and forces the motor to work almost non-stop. This leads to excessive energy consumption and rapid wear of parts.
| Surface type | Recommended gap | Permissible ambient temperature |
|---|---|---|
| Smooth wall | 5-7 cm | up to +32°C |
| Niche in furniture | 10 cm (back) | up to +30°C |
| Room corner | 15 cm (side) | up to +25°C |
| Near the window (sun) | Not recommended | Curtains required |
The floor on which the equipment is installed must be smooth and hard. If the floor is uneven, the refrigerator will wobble, causing vibration and noise when the compressor operates. Adjusting the legs allows you to compensate for small differences in height, but if there are serious defects in the coating, it is better to think about repairing it or moving the equipment.
Removing shipping elements and packaging
Before you begin setting up, you must empty the unit of all packaging materials. Manufacturers use a variety of securing elements to protect moving parts and fragile surfaces during transportation. Cardboard, tape, or foam left inside may block ventilation holes or interfere with the operation of mechanisms.
Carefully inspect the interior shelves and drawers. Manufacturers often secure them with tape or foam inserts to prevent the glass from breaking. Also check the space between the door and the body - there may be spacers there that prevent the door from opening spontaneously. All these elements must be carefully removed and disposed of.
Particular attention should be paid to the outer protective film. On many new models, plastic covers not only the handles, but also the control panel, and sometimes the inside of the doors. If this film is not removed, it may melt from the heat generated by the running motor, or simply prevent the seals from sealing tightly.
⚠️ Attention: Do not use sharp objects such as knives or blades to remove tape and stickers from the body. You can damage the paintwork or scratch the plastic, which will ruin the appearance of the equipment. Use mild solvents or special adhesive removers.
After removing all fasteners, wipe the internal surfaces with a damp cloth. Even if the chamber appears visually clean, production dust or particles of packaging foam may have settled on it. For the first cleaning, warm water with the addition of a mild detergent is sufficient.
Initial washing and disinfection
Hygiene is an important aspect of the operation of any devices that come into contact with food. Even if the refrigerator is new and just unpacked, its internal surface requires mandatory treatment. During the production, storage and delivery process, microparticles of dust, factory grease or bacteria may have gotten inside.
For washing, use warm water and a neutral detergent, for example, a weak solution of soda or a special product for caring for refrigerators. Aggressive chemicals, abrasive powders or chlorine-containing substances can damage the plastic coating of the chambers and rubber seals, making them brittle.
Thoroughly wash all shelves, vegetable drawers and containers on the door. If they are removable, it is better to take them out and wash them separately under the tap. After washing, be sure to wipe all surfaces dry with a clean cloth to avoid excess moisture getting inside before turning it on.
What should you not wash the refrigerator with?
Do not use gasoline, acetone, formic acid or abrasive cleaners. They can corrode the plastic, change its color or break the tightness of the seals. It is also not recommended to use hot water, as a sudden temperature change can lead to cracks in glass or plastic.
After completing cleaning, leave the doors open for a while so that all surfaces are completely dry and the smell of new plastic or rubber disappears. This odor is not dangerous, but can be transferred to highly absorbent products, such as butter or milk.
The process of first switching on and setting up
When all the preparatory steps have been completed, you can proceed to the most important moment - the first switching on. Make sure that the outlet to which the equipment will be connected is working, grounded and meets the power requirements. The use of extension cords or tees is not recommended as they can cause poor contact and overheating.
Insert the plug into the outlet. At this moment, you may hear a quiet click or hum - this is normal, the compressor starts working. On modern electronically controlled models, the display or indicators will light up immediately. If your model has a child lock feature, you may need to activate or deactivate it to access the settings.
For the first hours of operation, the refrigerator should operate idle, without loading food. This is necessary for the system to reach operating temperature conditions and for the sensors to read readings correctly. Usually this process takes from 2 to 6 hours, depending on the volume of the chambers and the ambient temperature in the room.
☑️ Checking the first start
During this period, do not open the doors unless absolutely necessary. Each opening leads to warm air getting inside, which increases the load on the compressor and delays the time to reach the desired temperature. Let the equipment quietly work out the full cooling cycle.
Operation control and loading with products
After the refrigerator has been empty for several hours, it is necessary to check the efficiency of its operation. Touch the side walls inside the chamber - they should be cold. The temperature in the freezer compartment should be below -18°C. If the model is equipped with a digital display, check the readings with the set values.
Loading of products should occur gradually. Don't fill all the shelves at once with large amounts of warm food. A sharp increase in temperature inside the chambers will force the compressor to work in increased mode for a long time. It is better to load food in small portions throughout the day.
Distribute food evenly, do not clog the ventilation holes. Cold air should circulate freely throughout the entire volume. If you notice that a “coat” of ice has formed on the back wall (in models without No Frost) or, conversely, the food in one corner is melting, this is a signal of incorrect settings or overload.
⚠️ Attention: During the first day of operation, the refrigerator may make unusual sounds: gurgling, clicking, crackling. This is due to the expansion and contraction of materials, as well as the movement of refrigerant through the system. If the noise is not accompanied by vibration of the case and is not constantly loud, this is normal.
Typical errors when starting up for the first time
Even careful study of the instructions does not always guarantee the absence of errors, since users often rely on intuition. One of the most common mistakes is ignoring settling time. The desire to quickly start using your purchase is understandable, but saving 4 hours of time may be worth the cost of a new compressor.
Another common mistake is installing the refrigerator close to the wall or in a niche without gaps. Owners forget that equipment “breathes”, and lack of ventilation leads to overheating. As a result, the refrigerator hums more than usual, and its sides can be very hot to the touch.
Also, many people forget to remove the shipping bolts or clamps from the compressor, if they are provided for in the design (although in modern household models this is less common than in washing machines, but it’s worth checking). Running the engine with locked shock absorbers will result in severe vibration and tube destruction.
Do not underestimate the importance of installation level. If the refrigerator is crooked, the door may not close tightly on its own. This leads to continuous operation of the motor, freezing of the seal and the formation of condensation on the floor.
What to do if the refrigerator does not turn on?
Check the presence of voltage in the outlet, the integrity of the power cord and the tightness of the plug. Make sure there are no power surges in the network. If everything is in order, but the equipment does not respond, perhaps the internal protection has worked or there is a manufacturing defect - contact the service center.
Frequently asked questions (FAQ)
Is it possible to turn on the refrigerator immediately after delivery if it was carried vertically?
Yes, if the refrigerator was carried strictly vertically, without tilting it more than 40 degrees, and there was no strong shaking, then it is enough to let it stand for 2-3 hours to stabilize the temperature of the electronics and oil. However, if there are doubts about the accuracy of transportation, it is better to play it safe and wait more time.
Do you need to wash the refrigerator before turning it on for the first time?
Absolutely. Particles of industrial dust, packaging or plastic smell may remain inside. Wipe the interior surfaces with a damp cloth and mild detergent and wipe dry. This will ensure hygienic storage of food.
Why does the refrigerator hum loudly during the first hours of operation?
When first started, the compressor works at full power to cool the empty volume of the chambers to the set temperature. This creates increased noise. In addition, the refrigerant actively circulates through the system, which may be accompanied by gurgling. Usually, after a few hours, when the temperature stabilizes, the noise will decrease.
How long can you load food?
It is recommended to fully load food no earlier than 4-6 hours after switching on, but it is better to wait a day. This will allow the system to fully reach operating mode and avoid unnecessary load on the compressor.
What to do if the refrigerator was transported in winter?
If the equipment comes into the heat from the cold, it needs to be given time to warm up to room temperature (at least 3-4 hours) to avoid condensation on the electrics. After this, you need to wait some more time for the oil to drain (at least 2-4 hours, preferably more), and only then turn it on.
