Buying a new refrigerator is always a joyful event, marking the updating of household appliances and improving food storage conditions. However, the joy of the purchase can be overshadowed if you ignore the basic rules of transportation and initial launch. Many owners make the mistake of believing that it is enough to simply insert the plug into the outlet and load the products, but a technically complex device requires a more careful approach.
Incorrect start-up can lead to failure of an expensive compressor, disruption of refrigerant circulation, or malfunction of the electronics. It is especially critical to follow the rules for equipment that was transported in a horizontal position or at subzero temperatures. In this article, we will analyze in detail all the stages, from unpacking to fully loading the shelves, so that your equipment will serve for many years without breakdowns.
Ignoring the settling time or a sharp temperature change can cause irreparable damage to the cooling system. Proper preparation is not just bureaucracy, but a necessary measure to maintain the warranty and performance of the unit. Let's look at what steps you need to take to safely activate your new device.
Dwell time: why you can't turn it on right away
The most common question that customers have is about the waiting time before turning it on for the first time. This is not a whim of manufacturers, but a physical necessity due to the design of the compressor. The compressor crankcase contains a special compressor oil, which during transportation can flow into the cooling system circuits, especially if the refrigerator was transported lying down.
If you turn on the unit immediately, the compressor will start to run “dry,” which will lead to rapid wear of rubbing parts and potential jamming. In addition, oil trapped in the heat exchanger will interfere with the normal circulation of the refrigerant. The settling time directly depends on the position in which the equipment was transported and what the ambient temperature was.
⚠️ Attention: If the refrigerator was transported in a horizontal position, the minimum settling time should be at least 8–12 hours. For vertical transportation, 2–4 hours are enough.
Temperature also plays an important role. If the equipment was brought in from the cold, condensation could form inside the housing and in the oil circuit. Turning on a wet electrical appliance is dangerous due to a short circuit. Therefore, if you brought a refrigerator in winter, let it stand in a warm room for at least a day, even if it was transported vertically.
What will happen if you do not wait for the time?
If you start a compressor with oil in the system, a water hammer may occur, which will disable the unit. Restoring after such damage is often not economically feasible.
It is important to understand that freon the system is under pressure, and a sudden start of the compressor with uneven distribution of liquids can break the tightness of the connections. (patience) in this case is the best investment in the durability of the equipment.
Preparation of the installation site and unpacking
Before proceeding with the electrical connection, it is necessary to properly prepare the installation site. The refrigerator must be placed on a flat, stable surface. Misalignment of the housing can lead to loose fitting of the doors, which will cause constant operation of the compressor and freezing of ice.
Use a building level to check the horizontal position. Height adjustment is usually done using the front support feet, which can be screwed in or out. Make sure that there is at least a 10 cm gap between the back of the refrigerator and the wall of the room to allow free air circulation and cooling of the condenser.
- 🧹 Thoroughly wipe the interior shelves and drawers with a damp cloth and mild detergent to remove factory dust.
- 🚚 Carefully remove all shipping packaging, including cardboard, polystyrene foam and tape.
- 🔧 Be sure to remove the fixing bolts or tapes holding the compressor or doors (if provided by the design).
- 🌡️ Check that the device is not in direct sunlight and away from heating devices.
Some models supplied with protective film on external stainless steel surfaces. It should be removed immediately, since under the influence of heat from a running refrigerator, the adhesive can polymerize, and the film will be extremely difficult to clean without damaging the coating.
Electrical connection and network requirements
The safety of operating the refrigerator directly depends on the quality of the electrical network. Modern compressors are sensitive to voltage changes, so it is recommended to connect the device to a separate outlet with mandatory grounding. The use of extension cords and tees is undesirable, as they can cause poor contact and heating.
Ideally, to protect expensive equipment, it is worth installing a voltage stabilizer or at least a surge protector with a surge protection function. If your network frequently experiences power outages, pay attention to refrigerator models with the function automatic restart or purchase an external controller.
| Parameter | Recommended value | Critical value |
|---|---|---|
| Main voltage | 220-230 V | Less than 190 V or more than 250 V |
| Grounding | Required | Absent |
| Socket type | With grounding contact | Without grounding |
| Cable length | Standard (usually 1.5-2 m) | Extended cable |
It is strictly forbidden to extend a standard network cable yourself. This not only voids the warranty, but also poses a fire risk. If the length of the wire is not enough, it is better to move the outlet or use a high-quality extension cord with a wire cross-section of at least 1.5 mm².
Initial start-up and operation check
After the refrigerator has settled down and is connected to the network, the moment of truth comes - the first start-up. An alarm indicator or sound signal may light up on the control panel indicating an increase in the temperature inside the chambers. This is normal, since the unit is still empty and warm.
Let the refrigerator run idle for at least 2-4 hours. During this time, it should reach the set temperature, and the compressor should turn off (or go into low consumption mode for inverter models). During this period, do not open the doors unless absolutely necessary, so as not to disrupt the cooling process.
Pay attention to the noise level. Modern refrigerators operate quietly, but the sound of the compressor running or refrigerant circulating (gurgling) is normal. However, extraneous knocks, body vibration or a loud hum should alert you.
⚠️ Attention: If after 5-6 hours of operation the compressor does not turn off and the temperature does not drop, check the tightness of the door seals. Perhaps the shipping tape interfered with closing.
☑️ Check after the first hour of operation
Models with the system No Frost are characterized by periodic activation of fans and defrost heaters. You may hear clicks or hissing - this is automatic operation. The main thing is that these sounds are not constant and sharp.
Setting the temperature
Correctly setting the temperature is the key to freshness of food and saving energy. You should not immediately set the minimum values, this will create an excessive load on the system. The optimal temperature for the main chamber is +4°C, and for the freezer - -18°C.
In mechanical models, adjustment is carried out by turning the thermostat, where the numbers indicate the cooling intensity, not degrees. Typically, the middle position (for example, 2 or 3 out of 5) is the most effective for everyday use.
Electronic control allows you to set the exact temperature in 1-degree increments. If you plan to store a lot of meat or fish in the freezer, you can activate the mode super freezes, but do not keep it on all the time so as not to wear out the compressor.
Remember that placing hot dishes inside is strictly prohibited. This leads to a sharp jump in temperature, condensation formation and increased load on the motor. Allow the food to cool to room temperature before putting it on the shelf.
Loading food and final checks
After the refrigerator has been idle for several hours and has returned to normal mode, you can begin loading. Do it gradually. Abruptly filling a large volume with warm (even room temperature) products can throw off the settings and force the compressor to work without rest.
Distribute products rationally: prepared meals and dairy products - on the upper shelves, raw meat and fish - on the lower ones, vegetables and fruits - in special drawers with humidity control. Do not place products close to the back wall, especially in drip models, so that they do not freeze.
- 🥩 Store raw meat in airtight containers on the bottom shelf.
- 🥛 It is better to place dairy products not on the door, but deeper in the chamber, where the temperature is more stable.
- 🍺 It is convenient to store drinks on the door, but do not subject them to defrosting cycles if the door is often opened.
On the first day, monitor the operation of the unit. If you notice that the door does not close tightly due to overfilling, or ice has formed on the walls, adjust the arrangement. Proper operation from the first days is a guarantee that the refrigerator will delight you with proper operation for many years.
Is it possible to turn on the refrigerator if it has just come out of the cold?
No, it is not possible. The refrigerator needs to warm up to room temperature (at least 4-5 hours) so that the condensation inside the electronic components evaporates and the oil in the compressor becomes fluid. Turning on a frozen unit will lead to a short circuit.
Why does the refrigerator hum after it is turned on?
The hum is the sound of the compressor operating. If the hum is monotonous and is not accompanied by vibration of the body, this is normal. If the sound is sharp, intermittent, or a knock is heard, the legs may be incorrectly positioned or there is a transportation defect.
Do you need to wash the refrigerator before first use?
Absolutely. Factory dust and the smell of plastic or packaging may remain inside a new refrigerator. Wipe all surfaces with a weak solution of soda or a special product for household appliances and wipe dry.
What to do if the refrigerator does not freeze after 10 hours of operation?
Check whether the door is tightly closed and whether the food is blocking the air duct damper. If after 12-24 hours the temperature does not drop and the compressor is running constantly, this is a reason to contact a service center; there may have been a freon leak during transportation.
