Buying a new refrigerator is always a joyful event, marking the beginning of comfortable operation of household appliances. However, the euphoria of the purchase often makes one forget about critically important rules, the violation of which can lead to the breakdown of an expensive unit in the very first days of operation. Many users make the fatal mistake of plugging the device into the network immediately after delivery, without taking into account the physical processes occurring inside the cooling system.
Modern models, whether budget Indesit or premium Liebherr, require compliance with a certain algorithm of actions before the first launch. Ignoring these rules, such as settling time or checking shipping bolts, may void the manufacturer's warranty and lead to failure. compressorIn this article, we will analyze in detail all the stages of preparation so that your refrigerator will serve for many years without failure.
It is important to understand that the installation process is not just “plugging a plug into a socket.” This is a set of measures, including site preparation, correct positioning of the body and primary diagnostics. Only by observing all technical nuances will you ensure stable operation refrigerant and efficient cooling of products.
The first thing the owner faces after purchase is logistics. Even if the refrigerator was transported carefully, internal components could become dislodged. Therefore, the algorithm of actions begins long before the moment of connection to the power grid. Particular attention should be paid to how exactly the transportation was carried out, since the need for additional time to stabilize the oil directly depends on this.
Transportation and settling time before starting
The main enemy of the compressor is the incorrect position during transportation. If the refrigerator was transported lying down, oil from the compressor inevitably flows into the cooling circuit, in particular into the evaporator and condenser. An attempt to start the unit in this condition will result in the compressor running “dry” or trying to push through the hydraulic plug, which can lead to instant failure.
The time required for settling directly depends on how exactly the equipment was transported and at what temperature. If transportation was carried out in a vertical position, 2-3 hours is enough. If the refrigerator was lying, it will take much more time for it to drain the oil back into the compressor crankcase.
⚠️ Attention: If transportation was carried out at temperatures below -5°C, the standing time should be increased to 4-5 hours after being brought into a warm room to avoid condensation on electrical components.
Why you can’t turn it on immediately?
The oil in the compressor has a high viscosity. With a sharp start, it does not have time to be distributed over the rubbing parts, causing backing and rapid wear. In addition, oil that gets into the refrigerant system disrupts heat transfer.
There is a common misconception that modern synthetic oils do not require settling. This is wrong. The physics of the process is the same for all types of lubricants used in refrigeration units. Give the equipment time to adapt to the room temperature and return the working fluids to the standard zones.
Preparing the place and unpacking the equipment
Before bringing the refrigerator into the kitchen, you need to make sure that the chosen location meets the manufacturer's requirements. Installation close to the wall or in a niche without gaps will lead to overheating condenser and increased energy consumption. Air must circulate freely around the heat exchanger, which is most often located on the back wall or on the sides of the case.
The unpacking process requires care. Remove all cardboard, foam pads and tape. Pay special attention to the interior space: there are often shelves, drawers and documentation there. Do not forget to remove all transportation locks, if they are provided by the design for doors or internal elements.
☑️ Checking the installation location
It is important to check the condition of the floor. If it is uneven, the refrigerator will vibrate and make noise. Most models, such as Bosch or LG, come with adjustable supports. They must be unscrewed so that the body is stable and the doors close tightly due to a slight tilt back.
Initial inspection and removal of shipping elements
After the refrigerator has settled, it is necessary to conduct a thorough visual inspection. Check the integrity of the case, the absence of dents and scratches. There should be no foreign objects inside the chamber, except for standard shelves. Make sure all plastic protective films are removed from the interior walls, otherwise odor and cleanliness may be affected.
A critical step is to check the back of the unit. There is a compressor, which is often secured with special bolts or brackets during transportation. If they are not removed before turning them on, vibration during operation will be transmitted to the entire body, causing loud noise and destruction of fasteners.
| Element | Location | Action | Consequences of ignoring |
|---|---|---|---|
| Transport bolts | Compressor base | Unscrew with a wrench | Vibration, noise, suspension breakdown |
| Shelf clamps | Inside cameras | Remove the tape/stops | Displacement of shelves, broken glass |
| Protective film | Internal walls | Remove completely | Foreign smell, stickiness |
| Packaging foam | Between boxes | Remove | Impaired air circulation |
Some models, for example, from the brand Haier, may have additional clamps for vegetable boxes. Carefully study the instructions for a specific model so as not to miss a single element. The absence of these parts in working order is the key to quiet operation.
Connecting to the electrical network and checking the voltage
A refrigerator is an energy-intensive device that requires a stable voltage. It should only be connected to a separate grounded outlet. The use of extension cords, tees and low-quality surge protectors is strictly not recommended, as they can cause a fire or unstable operation of the electronics.
Before plugging the plug into the outlet, make sure that the power cord is not damaged and the outlet is working properly. Modern inverter compressors are sensitive to voltage surges. If your network experiences frequent fluctuations, it is advisable to install a voltage stabilizer.
⚠️ Attention: Do not plug the refrigerator into the same outlet as powerful appliances (microwave, electric kettle) to avoid overloading the wiring.
After connecting, you will hear a quiet hum - this is the compressor starting. In the first minutes of operation, the system may make various sounds: gurgling of refrigerant, clicking of relays. This is fine. However, if you hear a loud knock or metallic clanging, the device must be turned off immediately.
First startup and setting temperature modes
After power is applied, the indicators on the control panel will light up. Depending on the model, this may be a digital display or a series of LEDs. The initial temperature setting is key. You should not immediately set the minimum values, this will create an excessive load on the system.
Optimal action algorithm:
- 🧊 Set the average temperature value for the refrigerator compartment (usually +4°C).
- ❄️ For the freezer compartment, the fast freezing mode or standard value is recommended -18°C.
- ⏱️ Let the refrigerator idle for at least 2-3 hours before loading food.
Many modern models, such as Samsung with system No Frost, have a quick diagnostic function. When you first turn it on, it may last several minutes. Don't interrupt this process. Electronics calibrates sensors and checks the operation of fans.
It is important to control thermostat operation. If after 3-4 hours of operation the chamber walls do not become cold and the compressor does not turn off even once, there may be a refrigerant leak or a malfunction of the thermostat. In this case, you should contact the service.
Loading food and checking the tightness
After the refrigerator has been idle and reached the required temperature, you can start loading. Do not fill the chambers completely with products at once. A sharp change in the thermal balance will cause the compressor to wear out. Load the products gradually, in small portions.
Be sure to check the tightness of the door. To do this, you can use a simple test with a sheet of paper: hold the sheet between the seal and the body and try to pull it out. If the sheet is easily removed, it means that the seal does not fit tightly and the hinges need to be adjusted.
⚠️ Attention: It is prohibited to place hot foods in the refrigerator! This disrupts the temperature regime and can lead to spoilage of already chilled food.
Distribute food evenly on the shelves without blocking the ventilation openings. Air circulation inside the chamber is the main condition for proper operation of the system No Frost or static cooling. Compliance with these rules will extend the life of your unit.
Frequent errors when first turned on
Despite the presence instructions, users continue to make common mistakes. The most common is ignoring the settling time. People rush to cool drinks or food faster, forgetting about the risks to equipment. The second mistake is installing the refrigerator near the radiator or in direct sunlight.
Incorrect temperature settings are also common. Users turn the knob to maximum, believing that this will cool the food faster. In fact, this only increases the operating time of the compressor without a significant gain in cooling speed.
- 🚫 Starting ahead of time (less than 2-4 hours after transport lying down).
- 🚫 Installation on an uneven floor without adjusting the legs.
- 🚫 Using extension cords and cheap power cords filters.
- 🚫 Loading with hot products during the first hours of operation.
Avoid these mistakes, and your refrigerator will become a reliable assistant in the kitchen. Remember that proper installation is an investment in the longevity of the equipment.
The myth about defrosting
Many people believe that modern refrigerators do not need to be defrosted. This is not entirely true. No Frost systems do not require defrosting from ice, but you need to wash the chambers and check the drain holes at least once every six months.
Questions and answers (FAQ)
How long should you wait before turning it on if the refrigerator was transported vertically?
If the equipment was transported strictly in a vertical position, it is enough to wait 1-2 hours. This time is necessary to stabilize the refrigerant and adapt the electronics to room temperature.
Is it possible to plug in a refrigerator via an extension cord?
Manufacturers categorically do not recommend using extension cords. They may not withstand the starting current of the compressor, which will lead to melted contacts or a fire. It is better to install an additional outlet near the installation site.
Why does the refrigerator hum loudly after the first turn on?
In the first hours of operation, noise can be caused by pumping refrigerant through the system and the operation of fans. If the noise does not subside after a day or is accompanied by vibration of the case, check whether the transport bolts have been removed.
Do you need to wash the refrigerator before first use?
Yes, definitely. Factory dust or plastic smell may remain inside. Wipe the interior surfaces with a damp cloth with a mild detergent or soda solution, then wipe dry.
What to do if the refrigerator does not cool after 5 hours of operation?
Check whether the door closes tightly and whether the ventilation holes are blocked by food. If the technical parameters are normal, but there is no cold, there may be a freon leak during delivery. A call from a specialist is required.
