Buying new household appliances is always a joyful event, which, however, requires the owner to comply with strict technical rules at the first start. Many users make the fatal mistake of turning on the unit immediately after they brought it home, without taking into account the physical processes that occurred with the oil and refrigerant during transportation. Incorrect activation can lead to compressor failure, capillary tube clogging or system leakage, which automatically voids the manufacturer's warranty.
Modern models Liebherr, LG or Indesit equipped with complex control systems and compressors that are sensitive to changes in pressure and temperature. In order for the device to serve the period stated by the manufacturer, it is necessary to give it time to adapt to room conditions and stabilize internal fluids before applying electrical voltage.
In this article we will analyze in detail the algorithm of actions that will help avoid costly repairs and ensure the correct operation of your equipment from the first minutes of operation. Critical Let's look at each stage of preparation and startup in detail.
Adaptation of equipment after transportation
Transporting a refrigerator is stressful for the entire cooling system, especially for the compressor, where the compressor oil is located. During movement, especially if the box was shaken, tilted or carried lying down, oil could flow from the compressor crankcase into the evaporator or condenser circuit. If you turn on the unit immediately, liquid oil entering the system can cause water hammer, which is fatal for the piston group.
The time that must be waited before turning on directly depends on the ambient temperature and the position of the equipment in the back of the truck. In winter, at sub-zero temperatures outside, the oil thickens and takes more time to warm up and spread throughout the system, even when turned off. In the summer, this process goes faster, but it cannot be ignored.
- 🕰️ If the refrigerator was transported vertically, the minimum settling time is 2-3 hours for the summer period and 4-5 hours for the winter.
- 🛌 When transporting horizontally (lying down), a minimum of 8 hours is required, and in the cold season - up to 12-15 hours for a full guarantee return oil to the compressor.
- ❄️ If the equipment comes into the room from the cold, do not turn it on for at least 4-5 hours until it has completely warmed up to room temperature to avoid condensation on the electronic boards.
Do not rush things by trying to start the unit to check the operation of the light bulb or display. Compressor oil must completely drain back into the tank, otherwise the system will operate with increased load, noise and risk of breakdown. In some models with inverter compressors, the requirements may be even stricter due to the design of the bearings.
⚠️ Attention: If you transported equipment at temperatures below -5°C, be sure to let it stand in a warm room without connecting to the network for at least 6-8 hours. Sudden heating of the internal components can lead to the formation of condensation on the contacts, which will cause a short circuit when turned on.
Initial inspection and preparation of the installation site
Before looking for an outlet, it is necessary to conduct a thorough visual inspection of the housing and the internal chamber. Make sure that the condenser tubes (usually the black grille on the back or sides) were not damaged upon delivery, as even a microscopic crack will cause a freon leak. Check the integrity of the rubber seals on the doors: they should be clean, elastic and fit tightly around the entire perimeter.
The choice of installation location plays a key role in the durability of the device. Refrigerator You cannot place it close to a wall or furniture, since air circulation is required for effective heat removal. The minimum distance from the back wall to the wall of the room should be at least 5-7 cm, and on the sides - 2-3 cm.
The floor surface should be flat and hard. If the floor is uneven, use adjustable feet to level the cabinet. This is necessary not only for aesthetics, but also for proper operation of the system No Frost and condensate drainage. An incorrect angle of inclination can lead to water accumulating inside rather than going into the drainage tray.
☑️ Initial inspection
It is also important to remove all packaging: cardboard, foam, tape and, most importantly, remove the protective film from the internal shelves and drawers. When heated, plastic can release harmful substances, and tape makes it difficult to open doors. Pay special attention to the shipping bolts or brackets on the compressor - if the manufacturer installed them, they must be unscrewed or removed before starting, otherwise vibration will destroy the fastenings.
Hygienic treatment of internal chambers
A new refrigerator, no matter how expensive and high-quality it is, requires mandatory washing before loading with food. During production and storage, factory dust, microparticles of plastic, grease or the smell of new materials may remain inside. Ignoring this step may result in off-flavors in the food in the future.
For washing, use a soft sponge and a warm solution of water with a neutral detergent or baking soda. It is strictly forbidden to use abrasive powders, hard brushes or aggressive chemicals containing acids or chlorine, as they can damage the antibacterial coating of the walls and plastic of the drawers. Thoroughly wipe down all shelves, drawers, door pockets and seals.
- 🧼 Use a baking soda solution (1 tablespoon per liter of water) to eliminate odors and disinfect.
- 💧 After washing, be sure to wipe all surfaces dry with a clean, soft cloth to prevent the formation of mold and ice.
- 🚫 Do not use hot water (above 40°C), as this can deform the thin plastic of the internal chambers.
After wet cleaning, leave the refrigerator doors open for 1-2 hours to completely dry and ventilate. This will also help to remove the specific “technical” smell characteristic of new plastic. If the smell persists, you can put activated carbon or a crust of black bread inside during the first downtime.
What should you not wash the refrigerator with?
Never use acetone, gasoline, solvents or chlorine-containing products (such as "Bleach"). They destroy the structure of the plastic, making it brittle, and can react with metal elements, causing corrosion. Also avoid melamine sponges - they act as a fine abrasive.
Electrical connection and voltage check
Connecting to the electrical network is the most critical moment. Make sure that the outlet to which you plan to connect the equipment is in working order, has grounding and corresponds to the required load. For modern refrigerators with powerful compressors and systems Smart Cooling it is recommended to use a separate outlet, without overloading the network with extensions or tees.
Grounding is a mandatory safety requirement, since the body of the refrigerator is metal, and in the event of an insulation breakdown, there may be dangerous voltage on it. If your wiring does not have grounding, it is recommended to consult with an electrician before installing expensive equipment.
| Network parameter | Norm for the Russian Federation/CIS | Risk of deviation |
|---|---|---|
| Voltage | 220-230 Volt | Compressor or control board combustion |
| Frequency | 50 Hertz | Incorrect operation timers and motors |
| Grounding | Required | Risk of electric shock when touching the housing |
If your region experiences frequent power surges, it is strongly recommended to install a voltage stabilizer or voltage control relay. Sudden changes can damage the electronic control module, the replacement of which costs significant money. Some models Bosch or Siemens equipped with built-in protection, but additional reinsurance will not hurt.
⚠️ Attention: Do not connect the refrigerator to an outlet that also includes powerful consumers (microwave, electric kettle, washing machine). The starting current of the compressor can cause a voltage drop, which will lead to malfunctions of all equipment in the kitchen.
First start-up and setting temperature conditions
After all the preparatory steps have been completed, you can plug the power cord into the outlet. On modern electronically controlled models, the display will light up and an audible signal may sound indicating that the door is open or the temperature is too high - this is normal. Mechanical models will start working immediately after power is applied.
Do not rush to load products! The first start should be in idle mode. An empty refrigerator takes from 2 to 12 hours (depending on the volume and type of cooling system) to reach the set temperature and stabilize. Loading warm products will immediately disrupt this process and cause the compressor to wear out.
- 🌡️ Set the average temperature values: +4°C for the refrigerator compartment and -18°C for the freezer.
- 🔌 Let the unit operate without load for at least 4 hours before loading food for the first time.
- 👂 Listen to the work: a quiet hum, gurgling of freon is allowed, but there should be no knocking, clanging or loud humming.
During operation, check the heating of the side walls or grilles at the back - they should be warm or hot, which indicates normal operation of the condenser. If the walls remain cold after several hours of operation, but the inside does not get cold, there may be a refrigerant leak or a compressor failure.
If your model is equipped with a system No Frost, make sure that the fans inside are working (air flow can be heard). In drip systems, check that the water does not drip onto the food, but flows into the drainage hole. At this stage, it is important to make sure that the doors close tightly and independently attract in the last centimeter of travel.
Loading food and monitoring operation
After the refrigerator has been idle for several hours and has reached temperature, you can begin to fill it. You should not load everything at once in the maximum volume - this will create a sharp temperature difference. It is better to do this gradually, allowing the system to cope with the load.
Place products according to zoning: dairy products and ready-made food - on the middle shelves, meat and fish (if you are preparing for cooking) - on the lower ones, vegetables and fruits - in special drawers below. Do not place warm food inside as this will increase humidity and load on the compressor. Air should circulate between the products; do not overcrowd the shelves.
On the first day of operation, monitor the cycle of turning the compressor on and off. It should not work constantly, but in periods: it reached the temperature - it turned off, the temperature rose - it turned on. If the motor hums without a break for more than 12 hours and does not turn off, and there is not enough cold inside, this is a sign of a malfunction.
Check the operation of the defrost system (for No Frost). A day or two after switching on, water may appear near the compressor (usually in a plastic tray) - this is normal, the condensate is evaporating. If water is pouring onto the floor, check the tilt level of the refrigerator; you may need to tighten the front legs.
Common mistakes when turning it on for the first time
Even carefully reading the instructions does not always save you from typical mistakes that users make. Most often, problems arise due to banal haste or ignorance of the physical properties of refrigerants. Understanding these mistakes will help you avoid service centers in the first year of operation.
One of the main mistakes is installing the refrigerator next to heat sources: a radiator, stove, or in direct sunlight. This forces the compressor to work almost non-stop, trying to compensate for external heat, which quickly leads to overheating and failure. It is also dangerous to place equipment in niches without ventilation.
- 🚫 Starting ahead of time: turning on immediately after delivery, ignoring the time for oil settling.
- 🔥 Installation at (heat sources): a violation of heat exchange leads to eternal operation of the motor.
- 📦 Abandoned transport fasteners: bolts on the compressor that are not allowed to be unscrewed cause severe vibration and destruction of the suspension.
Another common mistake is the use of chemical air fresheners inside the chambers. They can be absorbed into plastic and rubber seals, transferring odors to products. To eliminate odors, it is better to use natural absorbents, such as coal or special gel absorbers.
⚠️ Attention: If after the first turn on you hear a loud metal clang or smell burning wiring, immediately unplug the refrigerator from the outlet! Do not try to restart it. These are clear signs of a manufacturing defect or damage during transportation. Contact the service center under warranty.
Compliance with all the rules for the first start is an investment in the long life of your refrigerator. Proper preparation, patience during settling and proper setting of modes will allow the equipment to work quietly and efficiently for many years, keeping your food fresh.
How long can you not turn on the refrigerator after winter delivery?
If the refrigerator was delivered in winter at temperatures below -5°C, it cannot be turned on for at least 4-6 hours after being brought into a warm room. This time is necessary for condensation formed on internal parts and electronics due to temperature changes to completely evaporate. Turning on a wet appliance may cause a short circuit.
Does it need to be washed inside a new refrigerator before use?
Yes, definitely. Factory dust, packaging particles and plastic smell may remain inside. Wipe all surfaces with a damp cloth with a solution of soda or a mild detergent, then wipe dry and ventilate. This will prevent the appearance of foreign odors in the products.
Why does the refrigerator hum loudly when you first turn it on?
In the first hours of operation, the compressor may work more intensely than usual, gaining temperature. There may also be noise from the circulation of refrigerant in the pipes. However, if the hum is accompanied by vibration of the case, check whether the shipping bolts have been removed and whether the refrigerator is level on the floor.
Is it possible to place the refrigerator close to the wall?
No, it is not possible. To operate effectively, the cooling system requires heat removal. The minimum gap from the back wall to the wall of the room should be 5-7 cm, and on the sides - 2-3 cm. If there is no gap, the refrigerator will consume more electricity and will fail faster.
