Purchasing a new refrigerator - This is always a joyful event, marking the beginning of comfortable operation of household appliances. However, the joy of the purchase can quickly give way to disappointment if you ignore the basic rules for commissioning the equipment. Many owners make a critical mistake by connecting the unit to the electrical network immediately after delivery, which often leads to failure of the compressor or failure of the system's tightness.
Modern models from brands like Bosch, LG or Indesit are equipped with complex cooling systems that require a special approach when first started. Improper preparation can negate all the benefits of innovative technologies and shorten the service life of an expensive device. In this article we will analyze each stage in detail: from unpacking to the first loading of products.
Ignoring simple but mandatory procedures may result in denial of warranty service. Service centers can easily determine whether the transportation or launch technology has been compromised. Therefore correct start-up this is not just a recommendation, but a necessary condition for maintaining the functionality of your new assistant in the kitchen.
Transportation and settling time: why you can’t rush
The first and most important stage is keeping the device in an upright position after delivery. During transportation, especially if the refrigerator was lying on its side, oil from the compressor could flow into the cooling system circuits or the evaporator. If you turn on the unit immediately, the compressor will run dry, which will lead to rapid wear or jamming.
The time required for the oil to drain back into the compressor crankcase directly depends on the ambient temperature and the method of transportation. In winter, when equipment is delivered in cold weather, this process takes longer, since the viscosity of the oil increases at low temperatures. In summer, a shorter interval is sufficient, but you should still not neglect the wait.
⚠️ Attention: If the refrigerator was transported in a horizontal position, the minimum settling time should be at least 4-6 hours. In winter, at subzero temperatures, it is recommended to increase this period to 12–24 hours.
In addition, a sharp temperature change can cause condensation to form inside electrical circuits. Turning on wet electronics can result in a short circuit. Therefore, even if you transported the device upright (standing), let it sit in the room for 2-3 hours to acclimatize.
It is important to understand that compressor is the heart of the refrigerator, and its resource directly depends on the conditions of the first launch. The oil film must be completely restored to ensure lubrication of the rubbing parts. Rushing in this matter saves only a few hours of time, but jeopardizes the long-term service life of the equipment.
Unpacking, inspection and preparation for installation
After the refrigerator has settled, it is necessary to carefully prepare the place for its installation and conduct an external inspection. Packaging materials such as foam, cardboard and polyethylene must be completely removed. Pay special attention to the inside - often there are shelves, drawers and documentation that need to be removed before installation.
Remove all fixing elements. Manufacturers often use tape or special brackets to secure the compressor and doors during transportation. If you forget to remove them, vibration during operation can damage the fasteners or the unit itself. Check the integrity of the case for dents and scratches that may have appeared during delivery.
- 🧼 Carefully wipe the internal surfaces with a soft cloth soaked in a weak soda solution or a special product for household appliances.
- 🔍 Inspect the door seals for creases and make sure they fit snugly throughout perimeter.
- 📦 Remove all shipping bolts and stands, if provided by the design of your model Samsung or Haier.
The choice of installation location is also critically important. The refrigerator should be placed on a flat, hard surface away from direct sunlight and heating devices. The distance to walls and furniture should be at least 5–10 cm to ensure normal air circulation around the condenser.
Hygienic treatment before first use
A new refrigerator, no matter how expensive it is, smells like plastic and factory grease inside. This odor can be transferred to foods, especially dairy products and those with a soft texture. Therefore, sanitization is a mandatory step before loading food.
For washing, use warm water with the addition of baking soda or a mild detergent without aggressive abrasives. It is strictly not recommended to use chlorine-containing products, strong acids or solvents, as they can damage the plastic inner liner and rubber seals.
| Treatment area | Recommended product | What to avoid |
|---|---|---|
| Plastic shelves | Soda solution (1 tbsp per 1 liter of water) | Acetone, gasoline |
| Glass shelves | Glass cleaner | Boiling water (risk cracks) |
| Rubber seal | Warm water | Oils, alcohol |
| Metal elements | Wet wipe | Hard brushes |
After washing, be sure to wipe all surfaces dry and leave the doors open for 30–60 minutes for complete drying and ventilation. This will help eliminate residual odors and moisture that can contribute to the development of bacteria.
First connection to the power supply and checking operation
When the refrigerator is washed, installed and dry, you can begin connecting. Make sure the outlet you plug your equipment into is grounded and meets the wattage requirements. It is not recommended to use extension cords or tees, especially cheap ones, since the starting currents of the compressor can be high.
Plug in the device. At this moment thermostat or the electronic control panel should be activated. Set the temperature to the average value (usually +4...+5°C for the main chamber and -18°C for the freezer). Let the refrigerator run idle without food.
⚠️ Attention: During the first hours of operation, the refrigerator may make unusual sounds - gurgling of refrigerant, clicking of a relay or humming of the compressor. This is normal, but if the noise becomes unbearable or a burning smell appears, turn off the appliance immediately.
☑️ Check before loading
The time of the first run without load is usually from 2 to 4 hours. During this time, the unit should reach the set temperature and automatically turn off (if it is not a No Frost system with constant maintenance, but the cycle should still be visible in silence). Only after achieving stable cold can you load food.
Setting temperature modes and functionality
Modern refrigerators offer many operating modes that need to be configured to suit your needs. Models with the No Frost system require less attention to defrosting, but are sensitive to overload. Conventional drip systems require control of the drainage hole.
If your model has a Zero Zone, configure it separately. Usually the temperature is around 0...+2°C and high humidity, which is ideal for storing meat, fish and vegetables. For long-term storage in the freezer, make sure that the temperature has reached at least -18°C.
Electronic models often have a “Super Freeze” function or Super Freeze. Use it when loading a large amount of fresh food so that it freezes quickly and does not lose its properties. However, do not keep this mode on constantly, so as not to overload the compressor.
What is dynamic cooling?
Dynamic cooling (for example, Multi Air Flow) circulates cold air throughout all levels of the chamber, preventing the formation of zones with different temperatures and accelerating the restoration of cold after opening the door.
Do not forget that loading density affects operating efficiency. The refrigerator works best when it is about two-thirds full. An empty unit loses cold faster when the door is opened, and an overfilled one prevents air circulation.
Common mistakes during first startup and their consequences
Even following the instructions, users often make mistakes that can be costly. One of the most common is to install the refrigerator close to the wall or in a niche without gaps. This leads to overheating of the condenser and increased energy consumption.
Another mistake is loading warm or hot food into the refrigerator that has just been turned on. This forces the compressor to work overtime in an attempt to cool a large amount of heat, which can lead to compressor failure. Always cool food to room temperature before placing it inside.
- ❌ Placement near a stove, oven or radiator disrupts the thermal balance.
- ❌ Using aggressive cleaning chemicals destroys the structure of plastic and rubber.
- ❌ Closing the ventilation holes inside food chambers block the air flow.
It is also worth mentioning the quality of the power supply. Voltage surges are dangerous for refrigerator electronics. If your network has unstable voltage, it is recommended to use a stabilizer or at least a surge protector with overload protection.
FAQ: Frequently asked questions
Is it possible to transport the refrigerator lying down if there is no way to put it?
Transportation in a supine position is highly undesirable, but is possible if precautions are taken. You only need to lay it on the side opposite the side where the compressor tubes exit (usually the left side when viewed from the rear). After such transportation, the settling time should be increased to 12–24 hours.
Why does a new refrigerator hum loudly in the first days?
During the break-in period, the parts rub against each other, and the noise level may be higher than usual. Also, the volume depends on the levelness of the installation. If after 3-5 days the loud hum does not subside or rattling appears, check whether the pipes are touching the back wall of the cabinet and call a technician.
Is it necessary to defrost a new No Frost refrigerator before turning it on for the first time?
It is not necessary to defrost a new No Frost refrigerator before turning it on for the first time, since there is no ice. However, it is necessary to wash its inner surface with warm water and soda to remove the smell of plastic and factory dust.
How many hours after turning on can you load food?
You can load food only after the refrigerator reaches operating temperature. This usually takes 2 to 4 hours of idle operation. You can check readiness by assessing the cold inside the chambers or waiting for the first automatic shutdown of the compressor.
What to do if the refrigerator does not cool after the first turn on?
If after 4-5 hours of operation the walls are not cold and the food does not cool, there may be a freon leak during transportation or a manufacturing defect. Disconnect the device from the network and contact an authorized service center for diagnostics.
