The purchase of new household appliances is always accompanied by a wait, but immediately after delivery it is important not to rush into loading products. Correct initial operation of the device determines its service life and the efficiency of the compressor over many years. Many owners make the mistake of plugging the unit into the network instantly, which can lead to serious damage, especially if transportation was carried out in a horizontal position.
Modern models, whether reliable Liebherr or affordable Indesit, require some time to stabilize technical fluids and temperature balance. Ignoring simple preparation rules may void the manufacturer's warranty. In this article, we will analyze in detail all the stages: from unpacking to setting up optimal operating modes.
The first thing you need to do is to ensure that the device rests after moving. If the refrigerator was transported lying down, oil from the compressor could flow into the refrigerant circulation system, and it takes time to drain back into the engine crankcase. For vertical transportation, this period is shorter, but is still necessary for acclimatization of the electronics.
It is important to understand that Initial launch is stress for the compressor, so it must occur without load. Empty shelves will allow the system to quickly reach the set temperature, after which you can gradually fill the chambers with products. Do not neglect to study the instructions, as different brands may have their own nuances in management.
Initial preparation and unpacking
The process of mastering the technology begins long before connecting the cable to the outlet. External inspection of the case for dents and scratches is only the first stage. It is much more important to remove all transport elements that secure the moving parts inside the unit. People often forget to remove the tape from the internal shelves or the fasteners from the drawers, which can lead to their breakage the first time the door is opened.
Particular attention should be paid to the ventilation system. On the back wall or in the base there may be technological plugs or a protective film that blocks air access to the condenser. If these elements are not removed, heat transfer will be damaged, which will lead to overheating of the compressor and increased energy consumption.
⚠️ Attention: Be sure to remove all pieces of mounting tape from the internal surfaces. Over time, glue residues can absorb food odors and become a source of unpleasant odors that are difficult to remove.
After a visual inspection, it is necessary to thoroughly wash all removable elements. Factory dust, packaging foam residue, and chemical odors from new plastic must be eliminated. Use warm water with mild detergent or baking soda. Aggressive chemicals can damage the coating of shelves made of glass or plastic.
☑️ Initial preparation of the refrigerator
It is important to let the internal chambers dry completely before turning on. Humidity inside a confined space can contribute to the development of mold even before use. Wipe the surfaces with a dry soft cloth and leave the doors open for 15-20 minutes in a ventilated area.
Installation and proper placement
The choice of installation location is a critical factor in the durability of the equipment. The refrigerator should not be placed close to a wall or furniture. For normal operation of the heat exchanger, free air circulation is required. The minimum distance to the back wall should be at least 5-7 centimeters, and on the sides - about 10 centimeters.
The surface level plays a key role in the operation of the door mechanism and the tightness of the closure. If the floor is uneven, the door may not fit tightly, causing ice to form and the compressor to run continuously. Use a building level to check the horizontal position and adjust the height of the legs using a special wrench or screwdriver.
It is not recommended to install the unit near heat sources such as radiators, stoves or ovens. You should also avoid direct sunlight, which heats up the case and forces cooling system to work at its limit. The kitchen niche should be well ventilated.
The electrical network must also meet the requirements. The socket must be grounded and located in an accessible location so that, if necessary, you can quickly turn off the device. The use of extension cords and tees is undesirable, as they can heat up under load and create a risk of short circuit.
For models with the system No Frost it is important to ensure stability. Vibrations when the compressor operates on an uneven floor can create noticeable noise. After adjusting the legs, try to slightly rock the body - it should stand solidly and not wobble.
First switching on and setting the temperature
After the device has stood in a vertical position (at least 2-4 hours if transported standing, and up to 24 hours if lying down), you can begin the first launch. Plug the cord into the outlet and activate the device. On modern control panels, the indicators will light up and the compressor will start in a few minutes.
The first few hours of operation should be idle. Do not load the chambers with products immediately. Allow the system to cool down and shut down automatically. This will allow you to evaluate how well the temperature is maintained and whether there are any extraneous noises or vibrations. Normal time for the first cooling cycle can take from 4 to 8 hours.
| Storage area | Recommended temperature | What to store |
|---|---|---|
| Top shelf | +4...+6°C | Ready meals, dairy products |
| Middle shelf | +2...+4°C | Meat, fish, sausages |
| Bottom shelf | 0...+2°C | Perishable foods |
| Door | +5...+10°C | Drinks, sauces, eggs |
| Freezer | -18°C and below | Frozen semi-finished products |
The temperature setting depends on the model. In mechanical systems, this is controlled by a rotary knob numbered 1 to 7, where a higher number means a lower temperature. In electronic models, such as Samsung or LG, the temperature is set exactly in degrees through the display.
The optimal temperature in the main chamber is considered to be from +3 to +5 degrees Celsius. Lower values can lead to freezing of vegetables, and higher values can lead to the growth of bacteria. In the freezer, the standard is -18°C, which ensures long-term storage without loss of product quality.
Rules for loading products
When the refrigerator is in mode, you can begin filling. The main rule is not to overload the cameras on the first day. A sudden change in the thermal balance will cause the compressor to work without stopping, which is harmful to the new engine. Load food gradually, in small portions.
Distribute food according to temperature zones. The door is warmest, so there is room for sauces, drinks and foods with preservatives. Store ready-made dishes and milk on the upper shelves, and raw meat and fish on the lower shelves so that the juice does not drip onto other foods. It is better to keep vegetables and fruits in special boxes with humidity control.
⚠️ Attention: Never place hot or warm foods inside a working refrigerator. This sharply increases humidity and temperature, forcing the equipment to wear out, and can lead to spoilage of products already lying nearby.
Use the correct packaging. Products should be covered with lids or cling film so that odors do not mix and moisture does not settle on the walls. Raw meat is best stored in deep containers on the bottom shelf. Tight packaging also prevents food in the systems from drying out No Frost.
Do not overcrowd the shelves. Cold air should circulate freely between the products. If air flow is blocked, some areas may become warmer, causing the contents to spoil. Leave small gaps between packages.
Energy saving and efficient operation
Modern refrigerators have a high energy efficiency class, but improper use can reduce these advantages to zero. Frequent and prolonged opening of the door leads to loss of cold and the compressor turning on. Try to imagine in advance what you are taking in order to minimize the time the door is open.
Check the condition of the sealing rubber bands. If they are dirty or damaged, the seal is compromised. Wipe the seals with a soft, damp cloth once a month. To extend the life of the rubber, you can lubricate it with a special compound or glycerin so that it does not dry out or crack.
The myth of the empty refrigerator
There is an opinion that an empty refrigerator consumes less energy. This is not entirely true. A unit filled with products maintains temperature better, since the products act as cold accumulators. However, you cannot load it with warm foods. It is optimal to keep the refrigerator filled to 60-70%.
Regularly defrost the device, if so provided by the design. Even systems No Frost require preventive cleaning and shutdown once a year to wash and check the drainage holes. Clogged drainage is a common cause of puddles under the refrigerator.
Keep the condenser (grids at the back or bottom) clean. A layer of dust several millimeters thick significantly impairs heat transfer. Vacuum the back wall or plinth grille every 6 months. This is a simple procedure that extends the life of the compressor.
Typical operating mistakes
One of the most common mistakes is installing a refrigerator on an unheated balcony or in a garage. The climate class of the device determines the permissible range of ambient temperatures. Operation at temperatures below +10°C or above +32°C (unless an extended class is specified) leads to thickening of the oil in the compressor or incorrect operation of the thermostat.
The use of sharp objects to remove ice in chambers with manual defrosting is strictly prohibited. A puncture in the evaporator will lead to a freon leak and costly repairs, which are often not economically feasible. Defrost only naturally or using a hairdryer at a minimum temperature (without directing the hot jet at the plastic).
Ignoring strange sounds is another mistake. Humming, clicking or gurgling noises may be normal, but persistent knocking or vibration indicates a problem. Diagnostics early helps to avoid replacing expensive components. If the sound appears immediately after installation, check whether the cabinet is touching furniture or walls.
Do not store medications in the refrigerator unless this is indicated in the instructions for the drug. Temperature fluctuations when opening the door can ruin medications. It is also not recommended to store tropical fruits (bananas, pineapples) there, which turn black and spoil at low temperatures.
How long should the refrigerator sit after delivery?
If transportation was carried out in an upright position, 2-4 hours is enough. If the refrigerator was lying on its side or back, you need to let it stand for 8 to 24 hours. This is necessary to drain the oil into the compressor and equalize the pressure in the system.
Why is a new refrigerator loud?
In the first days of operation, the compressor may function more intensely than usual, gaining temperature. Noise can also occur due to uneven installation or the body touching furniture. If the loud hum does not subside after a week, you should call a technician.
Is it possible to place a refrigerator next to the battery?
It is highly not recommended. The minimum distance to heating devices should be at least 50 cm. The proximity of the heat source forces the compressor to work almost without interruption, which sharply increases energy consumption and wear of parts.
Do you need to wash a new refrigerator before use?
Absolutely. Factory dust, packaging particles and plastic odors may remain inside. Washing with warm water and soda or a mild detergent will remove these contaminants and ensure hygienic food storage.
What to do if an unpleasant odor appears in the refrigerator?
Wash the chambers with a solution of vinegar or citric acid. Place activated carbon, citrus peels or a special odor absorber. Check to see if food has gotten into the drainage hole.
