Buying a new refrigerator is always a joyful event, marking an update to kitchen appliances and improved food storage conditions. However, the joy of your purchase can quickly turn to disappointment if you ignore the critical initial launch phase. Many owners make the same mistake: they rush to fill the shelves with products and put the unit into operation immediately after delivery, without thinking about the internal physical processes that must be stabilized.
Ignoring the rules of preparation compressor and refrigerant for work can lead to a shortened service life of expensive equipment or even its breakdown in the first month of operation. In this article we will analyze in detail why you should not rush, how to properly prepare the internal chambers and what installation nuances will guarantee the quiet and efficient operation of your new equipment for many years.
Compliance with simple but mandatory procedures before first use is not a whim of the manufacturers, but a technical one a necessity dictated by the laws of physics and the design features of refrigeration machines. Let's figure out what exactly happens to the equipment during transportation and how to minimize the risks.
Why you can’t turn on the refrigerator immediately after delivery
The main reason why manufacturers categorically do not recommend turning on the unit immediately after delivery lies in the device of the compressor. This is the heart of the refrigerator, inside which there is compression oil that provides lubrication of rubbing parts. During transportation, especially if the box with the equipment was tilted or shaken, this oil could move from the compressor crankcase to the circuits refrigerant and heat exchangers.
If you start the engine in such a situation, the compressor will begin to work "on dry”, which will lead to rapid wear of the piston group and possible jamming. In addition, oil entering the circulation system can create an oil plug that will disrupt the normal circulation of freon, reducing cooling efficiency or causing overheating of the system.
⚠️ Attention: An attempt to start a compressor with migrated (displaced) oil can lead to water hammer, which is fatal to the mechanical part of the engine.
The second important aspect is the temperature regime. If delivery was made during the cold season, sudden temperature changes may cause moisture to condense inside electronic components and on contacts. Switching on wet electronics under voltage may result in a short circuit. Therefore acclimatization equipment in the room is necessary not only to drain the oil, but also to equalize the temperature of all components to room temperature.
How long does it take to defend the equipment
The time required to completely restore the normal state of the refrigeration system directly depends on the transportation conditions and the ambient temperature. There is no single figure for all cases, but there are clear recommendations that should be followed for different situations.
If the refrigerator was transported in an upright position and was not subjected to strong shaking, it is enough to let it stand in the off state for 2-4 hours. This time is usually enough for the remaining oil trapped in the tubes to flow back into the compressor crankcase under the influence of gravity. In this case stabilization it happens quickly and without risks.
It’s a completely different matter if the equipment was transported lying on its side or strongly tilted. In this position, the oil is guaranteed to flow deep into the evaporator and condenser. The rule here is simple: for every hour of transportation in a horizontal position, a minimum of 2-3 hours of settling in a vertical position is required. However, the minimum threshold in any case should not be less than 8-12 hours.
What to do if the refrigerator was delivered in winter?
If the equipment was brought in from the cold, do not turn it on immediately, even if it has been standing for 12 hours. Let it come to room temperature for another 3-4 hours after it has thawed. The condensation on the control board should completely evaporate.
Particular attention should be paid to winter delivery. Even if the box was in a warm car, being outside while unloading could cool the internal components. Running a cold compressor in a warm room creates thermal stress. Let the equipment stand with the doors open for at least a day if it is frozen.
Preparing the installation site and checking stability
Before unpacking the refrigerator and connecting it, you need to prepare the place where it will stand. Operating efficiency heat exchanger directly depends on the quality of ventilation around the housing. If the unit stands close to the wall or in a niche without gaps, the compressor will work with overload, trying to compensate for the lack of heat removal.
The optimal distance from the back wall of the refrigerator to the wall is at least 5-7 centimeters. Side gaps must also be at least 2-3 cm. For built-in models, the requirements are even stricter: it is necessary to comply with the dimensions of the ventilation ducts specified in the specific model. technical data sheet specific model.
| Installation type | Gap at the back (min) | Gap on the sides (min) | Gap at the top (min) |
|---|---|---|---|
| Free-standing | 5-7 cm | 2-3 cm | 5 cm |
| Recessed (in a niche) | according to instructions | per instructions | according to instructions |
| Recessed (under the countertop) | 5 cm | contact with furniture | 10 cm (ventilation duct) |
The second important point is the horizontal installation. The floor in the kitchen is rarely perfectly level, so using a spirit level when adjusting the legs of the refrigerator is mandatory. An incorrect tilt angle may result in the door not closing tightly on its own and the compressor vibrating more than usual.
⚠️ Attention: Adjust the height of the legs only after the refrigerator is fully loaded with food or weight simulators. An empty refrigerator may “settle” differently, and the settings will be lost.
Hygienic treatment of internal chambers
The inside of a new refrigerator may have a specific smell of plastic, factory grease or packaging materials. In addition, during the assembly process, dust could have settled on the shelves and walls. Before loading the first products, it is necessary to thoroughly sanitation all surfaces.
For washing, use a warm solution of baking soda or a mild detergent without abrasive particles. It is strictly forbidden to use aggressive chemicals, chlorine-containing products or hard sponges, which can damage the antibacterial coating or plastic. Pay special attention to the door seal - factory dust often accumulates in the folds of rubber.
☑️ Refrigerator preparation checklist
After washing, be sure to wipe all surfaces dry and Leave the doors open for several hours to completely remove odors. If the smell of plastic persists, you can use activated carbon or a crust of black bread, left inside for a day before turning it on.
Initial start-up and testing functionality
When the settling time is up, the place is prepared, and the chambers are washed, the moment of truth comes - the first turn on. Connect the refrigerator to a separate socket grounding connection. It is not recommended to use extension cords or tees as compressor inrush currents can be high and poor contact in the adapter can cause heat and fire.
After connecting to the network, you will hear the characteristic sound of the engine starting. Let the refrigerator run idle (without food) for at least 2-3 hours. During this time, the system should reach operating mode, and the thermostat will turn off the compressor when the set temperature is reached. If the motor has not turned off once in 3-4 hours, there may be a freon leak or the thermostat is faulty.
Check the operation of additional functions: whether the lamps are on, whether the fan is spinning (in models No Frost), whether the temperature is displayed correctly on the display. During the first hours of operation, the unit may operate louder than usual - this is normal, since it cools a large volume of warm air.
Typical mistakes during first use
Even knowing the rules, people often make mistakes that ruin all preparations. One of the most common is loading a large amount of warm food immediately after switching on. The refrigerator will try to cool them, working at maximum capacity, which can lead to overheating of the compressor in the first, most important hours of operation.
Another mistake is ignoring the instructions for a specific model. Modern refrigerators with inverter compressors or system Smart Cooling may have their own initial setup features that differ from classic models. For example, some “smart” refrigerators require time to calibrate sensors before starting active operation.
Also, users often forget to remove shipping bolts or fasteners, if any (although this is rare in household refrigerators, it is more common in wine cabinets). Be sure to check the package and remove all fixing elements, otherwise vibration during operation will be destructive.
Is it possible to transport a refrigerator lying down?
Technically it is possible, but it is extremely undesirable. If there is no other way out, place the refrigerator only on its side opposite the side where the tubes exit the compressor (usually indicated by an arrow on the body). After such transportation, the settling time should be at least 12-24 hours.
Why does the refrigerator hum after switching on?
The first start-up is always accompanied by a louder hum, since the compressor works continuously until it cools the chambers to the set temperature. You may also hear the sound of refrigerant gurgling - this is normal. If the noise does not subside after 5-6 hours or is accompanied by knocking, call a technician.
Do you need to wash the refrigerator before turning it on for the first time?
Yes, definitely. Particles of installation dust, the smell of plastic and packaging may remain inside. Washing with warm water and soda will remove dirt and prevent the first products from absorbing foreign odors.
What to do if the refrigerator does not turn off after the first start?
In the first 2-4 hours of operation, this is normal - active cooling is in progress. If the engine hums for more than 6-8 hours without a break and it is not cold inside, the thermostat may be faulty or there is a freon leak. In this case, you need to turn off the device and contact the service center.
