Buying new household appliances is always an exciting moment, especially when it comes to large-sized equipment, such as refrigerator. However, the joy of the purchase can be overshadowed if the basic rules of operation are neglected in the first hours after delivery. Many users make the fatal mistake of plugging the device into the network as soon as they brought it home and unpacked it, without thinking about the internal processes occurring in the compressor.
Transportation, even the most gentle, is stressful for a complex mechanism. Tilts, vibrations, vibrations and temperature changes can interfere with the proper circulation of refrigerant and oil. To avoid costly repairs or complete replacement of the compressor, it is necessary to clearly understand what stages the equipment must go through before the first start-up. In this article, we will analyze in detail the entire process, from unpacking to setting the temperature, so that your Indesit, Bosch or any other brand will serve for many years.
Ignoring the rules for initial start-up is the most common cause of breakdowns in the first year of operation. Statistics from service centers show that a significant percentage of calls are related to incorrect installation and startup. Let's figure out why rest interval is so important and how to prepare the unit for operation.
Why you can’t turn on the refrigerator immediately after transportation
The main reason for the need to wait lies in the design of the compressor - the “heart” of the refrigeration unit. Inside this unit there is a special oil that lubricates the rubbing parts and ensures tightness. During transportation, especially if the refrigerator was transported lying down or at an angle, this oil could leak from the compressor crankcase into the refrigerant circulation system.
If you turn on the unit immediately, the oil that gets into the circuit will create a hydraulic shock or simply cannot return to the crankcase, which will lead to the compressor running “dry”. This causes instant wear of the piston group and can cause the engine to wedge. In addition, oil in the heat exchanger (condenser or evaporator) significantly reduces cooling efficiency.
⚠️ Warning: Attempting to start the compressor with oil in the circuit may result in permanent damage that is not covered under warranty. The wizard can easily determine a violation of operating conditions based on the state of the system.
The second important aspect is the temperature regime. If delivery was carried out in winter at subzero temperatures, the internal components and the oil itself could cool below acceptable values. Cold oil becomes thick and viscous, losing its lubricating properties. A sudden start of such a mechanism is tantamount to trying to start a car engine in severe frost without warming up.
How long does it take to stand for equipment
The time required to stabilize internal systems directly depends on transportation conditions and ambient temperature. There is no single figure for all cases, but there are generally accepted standards that engineers and manufacturers adhere to. Settling It is necessary to ensure that the oil flows back into the compressor, and the temperature of all components is equal to room temperature.
The table below shows the approximate holding times depending on the season and position at transportation These data are relevant for most modern models with classic compressors.
| Transportation conditions | Season | Recommended settling time |
|---|---|---|
| Vertical position | Summer / Warm | 2–4 hours |
| Vertical position | Winter / Cold | 4–6 hours (until fully warmed up) |
| Horizontal position (on the side) | Summer / Heat | 8–12 hours |
| Horizontal position (on the side) | Winter / Cold | 12–24 hours |
It is worth noting that for models with inverter compressors requirements may be slightly less strict regarding the position during transportation, but the rule of temperature adaptation remains unchanged. If you do not know exactly how the equipment was transported (for example, you bought used or did not supervise the loaders), it is better to play it safe and wait the maximum period - a day.
Why do you need to wait longer in winter?
In winter, the problem is not only oil, but also condensation. When a cold device is brought into a warm room, moisture forms on the internal parts and electrical contacts. If you turn on the device ahead of time, a short circuit may occur. Therefore, in winter, it is important to let the equipment not just stand, but rather warm up to room temperature.
Preparation for the first launch: unpacking and inspection
Before thinking about connecting to the electrical network, it is necessary to conduct a thorough visual inspection and prepare the installation site. Correct installation affects energy consumption and noise level. First, remove all packaging: cardboard, foam plastic and, most importantly, the tape securing the doors and drawers.
There may be accessories inside the refrigerator and freezer compartments: shelves, egg trays, instructions. They need to be removed, washed with warm water and a mild detergent and dried. It is also advisable to wipe the camera itself with a damp cloth to remove factory dust or possible plastic odors. Do not use abrasives or aggressive chemicals.
- 🧼 Wash all removable shelves and drawers with warm water and soap.
- 🔍 Carefully inspect the cabinet for dents and chips that occurred during delivery.
- 🚪 Check the tightness of the doors and operation of the seals.
- 📄 Remove all shipping stickers and fasteners.
Pay special attention to the rear of the unit. Make sure the condenser (grid at the back) is not dented and the tubes are not pinched. If you find serious mechanical damage to the case, it is better not to turn on the device, but immediately contact the store to fill out a report of damage.
☑️ Check before turning on
Selecting a location and setting the level
The correct location of the refrigerator is the key to its quiet operation and effective cooling. Do not place the device close to the wall or in a niche without gaps. For normal air circulation around the condenser, it is necessary to leave free space. The minimum gaps are usually 5–10 cm from the back wall and 2–3 cm on the sides.
A critically important point is level installation. The floor under the refrigerator must be level. If the floor is uneven or tiled with joints, adjustable feet must be used. Incorrect tilt may result in the door not closing tightly on its own, or, conversely, opening too easily, breaking the seal.
Use a building level to make adjustments. Place it on the top panel of the refrigerator, first lengthwise, then crosswise. Tighten the front legs with a wrench or by hand (depending on the model) until the level bubble is exactly in the center. Many modern models have a slight natural tilt back for self-closing doors, but skewing to the left or right is unacceptable.
⚠️ Attention: Make sure that the outlet to which you plan to connect the refrigerator is working and grounded. The use of extension cords and tees is not recommended, as they can cause heating of the contacts and a fire during prolonged operation of a powerful compressor.
First switching on and setting the temperature
After the refrigerator has stood for the required time and has been set to the level, you can proceed to the most important moment - the first switching on. Insert the plug into the outlet. In modern models with electronic control, the display will immediately light up; in simpler ones, a characteristic sound of the compressor starting or a relay click may be heard.
Do not rush to load products! An empty refrigerator must run for several hours to reach the required temperature in the chambers. Typically this process takes from 2 to 4 hours, depending on the volume of the chambers and the ambient temperature in the room. Loading warm foods will immediately upset the temperature balance and cause the compressor to work overload.
It is best to set the temperature according to the instructions for the specific model. Standard values for normal operation: +2...+4°C in the refrigerator compartment and -18°C in the freezer compartment. If the model has a zone Zero Zone or “Zero chamber”, set it to 0°C for storing meat and fish without freezing.
Is this normal: sounds and heating at start-up
In the first hours of operation, a new refrigerator may behave differently than the usual old equipment. Users are often frightened by sounds that are actually a sign of normal operation of modern systems. For example, gurgling, liquid pouring or quiet hissing is the sound of circulating refrigerant freon in the tubes.
Heating of the side walls or the space between the doors may also be observed. In modern models, heating circuit pipes often pass there, preventing the formation of condensation and ice on the seals. Therefore, warm sidewalls are not a defect, but a design feature.
- 🔊 A quiet hum or vibration is the work of the compressor.
- 💧 Gurgling is the movement of refrigerant through the system.
- 🔥 Heating of the side walls is the work of the anti-condensation circuit.
- 🔨 Clicks - the thermostat or protection relay is triggered.
However, if you hear a loud knock, metal grinding or whistling, this is a reason to be wary. Also an alarming signal is the situation when the compressor runs continuously for more than 10–12 hours without turning off, and the temperature inside does not drop. In this case, you need to turn off the device and contact a service center.
Why does the refrigerator crack?
Plastic and metal have different coefficients of thermal expansion. When cooling or heating, parts may make a cracking sound. This is especially noticeable in new refrigerators and usually goes away after a few days of operation.
Common mistakes when starting new equipment
Even knowing the rules, people manage to make mistakes that shorten the life of the equipment. The most common of them is ignoring the manufacturer's instructions. Each brand (Samsung, LG, Haier) may have its own nuances, for example, the need to activate the transport mode or a specific startup sequence.
Another mistake is installing the refrigerator near heat sources: a radiator, stove, or in direct sunlight. This forces the compressor to work almost without interruption, trying to compensate for external heating, which leads to rapid failure.
Do not forget about ventilation. Built-in models require a special approach: if you do not ensure the correct inflow and outflow of air in the niche, the refrigerator will simply “suffocate” and consume many times more electricity. Always check the installation requirements in the technical data sheet.
Is it possible to transport the refrigerator lying down and after how long to turn it on?
Transporting it lying down is highly not recommended, but if there was no other choice, the settling time should be maximum - at least 12-24 hours. This is necessary so that the oil is guaranteed to flow into the compressor. If you were transporting standing, 2-4 hours is enough.
What to do if the refrigerator does not freeze after turning it on?
First, check whether the door is tightly closed and whether it is loaded with food. Let it run empty for 5-6 hours. If the temperature does not drop, there may be a freon leak during transportation or a compressor breakdown - call a technician.
Do you need to wash the inside of a new refrigerator?
Yes, definitely. During production and storage in a warehouse, dust, shavings or packaging odors could get inside. Wipe the chambers with a weak solution of soda or a special product for refrigerators, then wipe dry.
Why is a new refrigerator humming?
Modern compressors can make background noise. If the hum is uniform and quiet, this is normal. If the sound is sharp, intermittent or very loud, check whether the refrigerator is touching the wall or furniture, and whether it is level.
How long can you load food?
It is recommended to fully load food after the refrigerator has been empty for 2-4 hours and reaches operating temperature. It is better to load in small portions so as not to create a sharp temperature difference.
