Buying a new refrigerator is always a joyful event, marking an update of household appliances and an improvement in food storage conditions. However, the euphoria of the acquisition should not overshadow the need to comply with strict technical regulations when launching for the first time. Errors at the unpacking or installation stage can lead to compressor failure long before the end of the warranty period.
Modern units, whether budget models or premium Side-by-Side systems, require careful attention to transportation and preparation for work. Many users make the fatal mistake of plugging the device into the network as soon as it is in the kitchen. This is strictly prohibited for equipment that was tilted during delivery.
In this article we will analyze all the stages: from checking the integrity of the case upon receipt to the first loading of products. You will learn why settling time is a critical parameter and how to correctly set temperature conditions for maximum energy efficiency.
Visual inspection and check of equipment
The first thing that needs to be done immediately after delivering the equipment to the apartment is a thorough external inspection. Couriers are often in a hurry, and your task is not to miss mechanical damage that could occur along the way. Dents on the body can be not only a cosmetic defect, but also a sign of an impact that can damage the internal tubes of the cooling system.
Open the doors and carefully examine the interior space. The plastic of shelves and drawers must be intact, without cracks or chips. Pay special attention to the door seal: it should fit snugly around the entire perimeter and not have any creases. If you find defects, do not sign the acceptance certificate without making notes about this.
- 🔍 Check the integrity of the glass shelves for microcracks.
- 🚚 Make sure that the transport bolts and compressor clamps are removed (if they were).
- 📄 Keep the warranty coupon and instructions in an accessible place.
⚠️ Attention: If, during an external inspection, traces of oil are visible under the refrigerator or a strong smell of freon is felt, immediately stop the installation and call specialists. This may indicate depressurization of the circuit.
Don't forget to check the package. In some models, egg trays, bottle racks or special trays may lie separately inside the chambers, rather than being installed in place. It is better to check the presence of all elements with the list in the user manual.
Transportation and rest time: a critical stage
The most important question that owners have: how long should the refrigerator sit for after purchase before turning it on? The answer directly depends on the position in which the transportation was carried out. Oil from the compressor, when tilted or shaking, could get into the refrigerant circulation circuit, and it needs time to drain back into the crankcase.
If the equipment was transported strictly vertically, the waiting time is minimal. However, in reality, elevators and doorways often require the body to tilt. In this case, stabilization of liquids comes into effect. Ignoring this stage can lead to water hammer in the compressor at startup. temperature adaptation rule and stabilization of liquids. Ignoring this step may result in water hammer in the compressor upon startup.
Let's consider the dependence of the standing time on transportation conditions in the table below:
| Transportation conditions | Ambient temperature | Recommended settling time |
|---|---|---|
| Vertical | Warm season (+20°C and above) | 1–2 hours |
| Vertical | Cold season (below 0°C) | 3–4 hours (after being brought into the heat) |
| Inclined | Any | 4–8 hours |
| Lying position | Any | 12–24 hours |
It is worth noting that if the refrigerator is brought in from the cold, you cannot turn it on immediately, even if it has stood for the required time. Sudden temperature changes can cause condensation on the electronic control boards, resulting in a short circuit.
Installation and alignment of the housing
Correct installation affects not only the appearance, but also the operation of the compressor and the self-closing door system. The refrigerator must be placed on a flat, hard surface. Tile or linoleum can slide, so it is important to ensure that the unit is stable.
The front support legs are used to adjust the height. They are usually unscrewed with a key or by hand, depending on the model. The rear wheels or stops can also be adjusted, but less frequently. The main goal is to achieve a strictly horizontal position, which is checked by a building level.
- 📐 Use a building level to check the horizontal position along the top edge.
- 🚪 Adjust the legs so that the door opens freely and slams itself when opened up to 30 degrees.
- 🌬️ Ensure the gap between the back of the refrigerator and the wall is at least 5-7 cm for air circulation.
Improper installation often causes increased noise and vibration. If the refrigerator is skewed, the oil in the compressor is distributed unevenly, which increases wear on the rubbing parts. In addition, a skewed door may not provide a seal, and ice may build up.
⚠️ Attention: Do not install the refrigerator near heat sources (radiators, stoves) or in direct sunlight. This forces the compressor to work with increased load, increasing energy consumption.
Primary processing and disinfection
Before loading products, the internal space must be prepared. New materials, plastics and seals may have a specific technical smell. In addition, dust may have accumulated on the shelves during storage or transportation.
For cleaning, use a weak solution of baking soda or a mild detergent. Aggressive chemicals, abrasive powders and chlorine-containing substances can damage the internal plastic coating and rubber seals. After wet cleaning, the doors should remain open until completely dry.
☑️ Preparation for the first start
Pay special attention to the system No Frostif it is present. Although these models do not require defrosting, the condensate drainage channels must be clean when first started. Make sure that there is no debris in the drainage hole (if it is accessible for inspection).
If the smell of plastic persists after the first wash, you can use the traditional method: place lemon slices or an open pack of activated carbon inside. This will help absorb extraneous odors before use.
First start-up and setting the temperature
After the refrigerator has settled, warmed up and been washed, the moment of truth comes - the first turn on. Plug the power cord into a separate grounded outlet. The use of extension cords and tees is not recommended, as the starting currents of the compressor can be high.
Plug in the unit, but do not open the doors yet. Let it run idle. Modern inverter compressors can start out very quietly, so place your hand on the side wall to feel the vibration or heat from the condenser.
Why does the refrigerator hum when you first turn it on?
In the first minutes of operation, a stronger hum or gurgle may be heard. This is normal: the refrigerant begins to circulate through the system, and the compressor returns to operating mode. After 15-20 minutes, the sound should become quieter.
Adjust the temperature according to the instructions. The optimal temperature for the main compartment is +4°C, and for the freezer -18°C. You should not immediately set the minimum values if the chamber is still warm - this will create an extra load.
- ❄️ Set the thermostat to the middle position for initial cooling.
- ⏱️ Let the refrigerator operate for 2-3 hours without loading food.
- 🌡️ Check the temperature inside after 4-5 hours using a thermometer.
It is important to understand that reaching the set temperature takes time. In an empty chamber, the air cools faster, but the plastic itself and the shelves still retain the heat of the room. Therefore, loading with products should occur gradually.
Loading with products and operating modes
When the refrigerator has been idle for several hours and has reached temperature, you can begin loading. However, you shouldn’t fill all the shelves to capacity at once. A sudden influx of large quantities of warm food will force the compressor to work at its limit.
Distribute the food evenly. It is better to place heavy bottles and cans on the lower shelves or in door niches designed for them. Do not block the openings of the ventilation system inside the chamber, especially in models with No Frost, otherwise the cold will not circulate correctly.
Monitor the operation of the unit in the first week. If you notice that the refrigerator is running non-stop, excessive frost forms on the walls, or food in different corners of the chamber has different temperatures, you may need to adjust the settings or check the seals.
What to do if the refrigerator does not cool after the first turn on?
If after 5-6 hours of operation the temperature inside has not dropped, check whether the doors are tightly closed. Make sure the thermostat is not set to low. If the problem persists for more than 12 hours, contact the service center - there may be a manufacturing defect or a freon leak.
Is it possible to place a refrigerator on a balcony?
Most refrigerators are designed for operation in the SN-N-ST-T climate class, which implies an ambient temperature from +10°C to +38°C (or +43°C). Installation on an uninsulated balcony in winter or under the scorching sun in summer will damage the equipment and void the warranty.
Do you need to wash the refrigerator before first use?
Yes, definitely. Interior surfaces may have come into contact with dust, packaging materials, and the hands of assemblers. Use a soft cloth and a mild soap solution, then rinse thoroughly and wipe dry.
Why can’t you turn on the refrigerator immediately after transportation?
During transportation, oil from the compressor may have flowed into the pipe system. If you turn on the unit immediately, the compressor will try to compress the liquid (oil and freon), which will lead to water hammer and failure of the piston group. It is necessary to allow the oil to drain back.
What temperature should be in the new refrigerator?
The optimal temperature in the main chamber is from +2°C to +5°C. For long-term storage of food in the freezer, it is necessary to maintain -18°C or lower. The exact values depend on the type of food you plan to store.
