Buying a new refrigerator is always a joyful event, marking the update of household appliances in the kitchen. However, joy can quickly give way to disappointment if you ignore the basic rules for transporting and initial startup of the unit. Many owners make the fatal mistake of plugging the device into the network immediately after bringing it into the apartment, which can lead to serious damage to the compressor.
Correct installation of a refrigerator is not just a matter of aesthetics or ease of use, but a critical stage that ensures long service life of the equipment. Incorrect positioning, ignoring clearances for ventilation or neglecting the adaptation time of the oil in the compressor often become the reasons for expensive repairs.
In this article we will analyze in detail each stage: from the moment you brought the box into the hallway to loading the first products. You will learn why you shouldn’t rush, how to perfectly align your body, and what nuances exist for different types of equipment. Following these simple but important rules will allow you to avoid common mistakes.
Initial inspection and unpacking of equipment
The process unpacking should be as careful as possible so as not to damage either the refrigerator itself or the floor covering. First you need to clear the passage and prepare the place where the unit will be installed. Remove the top cardboard box, but do not remove the sides completely yet to use them as protection when moving.
Carefully inspect the case for dents, chips or scratches that may have occurred during delivery. Pay special attention to doors and handles. If you find any defects, they must be recorded in the acceptance certificate before the documents are signed by the courier. Also check the equipment: the presence of shelves, drawers, trays for eggs and documentation.
⚠️ Attention: Never use sharp objects (knives, scissors) to open the packaging close to the body. One awkward move can damage the No Frost system or ruin the coating, which will void your warranty.
Internal elements are often secured with tape or foam for protection during transportation. All these fasteners, as well as the protective film from the internal and external surfaces, must be completely removed. Leave only those elements that are indicated in the instructions as non-removable.
Choosing a location and ventilation requirements
Choosing the right location is the foundation of stable work refrigerator compartment. Modern models require free space for air circulation, since the heat removed from the condenser must go somewhere. If you install the unit in a niche without gaps or close to the wall, the compressor will work with overload.
It is strictly not recommended to place the refrigerator next to heat sources, such as radiators, ovens or stoves. You should also avoid direct sunlight, which heats the case and makes the equipment work more intensely. The ideal distance from heating devices should be at least 40-50 cm.
To ensure proper heat exchange, the following minimum gaps must be observed:
- 📏 From the back wall to the wall - at least 5-7 cm for free air circulation.
- 📏 From the side walls to the furniture - minimum 2-3 cm on each side.
- 📏 From the top of the case to the ceiling or shelf - at least 10-15 cm.
If you plan to build a refrigerator into a kitchen set, make sure that the model is designed for built-in. Free-standing models cannot be placed in a closed cabinet, as this will lead to overheating and failure of the compressor compressor.
Aligning the case and adjusting the supports
After the refrigerator is placed in its permanent place, you need to start leveling it. This is a critical stage on which the tightness of the door, the correct operation of the self-closing system and the absence of unnecessary noise during vibration depend.
Most modern models are equipped with adjustable front legs. By rotating them clockwise or counterclockwise, you can change the height of the corner of the unit. The rear mounts are usually non-adjustable, so all adjustments are made from the front. For precise work, use a building level, installing it on the top cover.
| Parameter | Recommended value | Consequences of violation |
|---|---|---|
| Tilt back | 1-2 degrees | The door will not close on its own |
| Horizontal misalignment | 0 degrees | Frame misalignment, noise, hinge wear |
| Gap at the wall | 5-7 cm | Overheating of the condenser |
The correct position is when the refrigerator stands firmly on all four supports, and its door, if opened to 45 degrees, closes smoothly and independently. If the door does not close on its own, the front legs need to be unscrewed a little more, tilting them further back.
⚠️ Attention: Do not leave the refrigerator standing only on its rear wheels or in a shaky position. This will lead to constant vibration, hum and eventual breakdown of the evaporator tubes due to resonance.
Standing time before turning on
One of the most important questions is how long after delivery the refrigerator can be turned on. The answer depends on transport conditions and ambient temperature. During transportation, especially if the equipment was placed on its side, oil from the compressor could flow into the circuits of the cooling system.
If the refrigerator was transported in an upright position and the temperature outside was above zero, it is enough to let it stand for 2-3 hours. This time is necessary to stabilize the temperature of the internal components after frost and the settling of possible suspensions in the oil.
If transportation took place in a horizontal position or there was severe frost outside (below -5°C), the settling time increases:
- ❄️ After transportation in winter - at least 4-6 hours in a warm room.
- 🛌 After transportation on its side - from 8 to 12 hours, so that the oil flows back into the crankcase.
- 🌡️ Combined conditions (winter + lying position) - up to 24 hours.
An attempt to start unit before time can lead to water hammer in the compressor. Oil that gets into the capillary tube creates a plug, and the compressor begins to work "breaking", which often ends in its combustion or destruction of the valves.
Why does oil get into the system?
When the refrigerator is tilted more than 40 degrees, liquid oil from the compressor crankcase flows into the refrigerant circuit. If you turn on the motor right away, it will try to compress the incompressible liquid, which will cause critical pressure.
First start and test of functionality
After the refrigerator has settled, you can proceed to the first start. Plug the power cord into a separate grounded outlet. The use of extension cords or tees is not recommended as compressor starting currents may be high. Make sure that there are no foreign objects inside the chamber and that the shelves are level.
Turn on the device and set the temperature to medium. For the main chamber this is usually +4...+5°C, for the freezer - -18°C. Do not load products during the first few hours of operation. It is easier for an empty refrigerator to gain the required temperature and stabilize the mode.
Pay attention to the following signs of normal operation:
- 🔊 The compressor operates smoothly, without knocking, clanging or sharp clicks.
- ❄️ The internal walls begin to cool evenly (check through 30-40 minutes).
- 💧 In some models, water may appear under the vegetable container or in the gutter - this is condensation, which is normal.
If you hear gurgling or gurgling, do not be alarmed. This is normal for modern refrigerants that circulate through the system. However, a constant loud hum or vibration of the case indicates improper installation or defect.
☑️ Check after the first start
Loading food and final settings
You can load food only after the refrigerator has entered operating mode. Typically this process takes from 4 to 8 hours depending on the volume of the chambers and the ambient temperature. You can understand that the mode is set by the first automatic shutdown of the compressor.
Do not fill the chamber with warm products. This will create a huge load on cooling system and will lead to prolonged operation of the motor without rest. Also, do not overcrowd the refrigerator on the first day - cold air should circulate freely between the products.
Distribute products according to zoning:
- 🥩 Raw meat and fish - on the lowest shelf or in the zero temperature zone.
- 🥛 Dairy products and prepared foods - on the middle shelves.
- 🥤 Drinks and heavy bottles - on the door shelves (it's warmer there).
- 🥦 Vegetables and fruits - in the bottom drawers, where the humidity is higher.
⚠️ Attention: Manufacturers can change recommendations on temperature conditions for different series of equipment. Always check the official manual of your model refrigerator before setting specific modes (for example, "Super Freeze" or "Eco").
Frequently asked questions (FAQ)
Is it possible to place the refrigerator on linoleum or carpet?
You can put it on linoleum, but it is advisable to place a durable one a backing (for example, a piece of plywood or a rubber mat) if the legs are sharp. It is not recommended to place it on carpet, since the pile will block the access of air to the bottom of the case, which will disrupt heat transfer.
Why does the refrigerator hum after installation?
The hum can be caused by the case touching the walls or furniture, as well as an uneven floor. Check the gaps and adjust the legs. If a new compressor is humming, this may be a feature of the model, but a loud clang requires calling a technician.
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 with a solution of warm water and baking soda or a weak solution of vinegar.
What to do if the door does not fit tightly?
Check if anything is interfering with the seal (packaging, labels). Make sure the refrigerator is level. If there is no distortion, but there is a gap, the seal may have been deformed upon delivery, it can be heated with a hairdryer or replaced.
How long does it take the refrigerator to reach temperature for the first time?
The first start to operation takes longer than usual - from 4 to 10 hours. During this time, the compressor can operate almost without interruption. This is normal, do not open the door during this period.
