Correct setting of the temperature regime is the foundation on which it rests the durability of your refrigerator and the freshness of your food. Many equipment owners Atlant erroneously believe that it is enough to simply turn the thermostat knob towards the maximum value to achieve ideal cold. In fact, hypothermia is as dangerous as insufficient cooling, since it can lead to damage to the structure of products and increased energy consumption.
The question of how many divisions or degrees to set the regulator does not have a universal answer for all situations. It depends on the time of year, the workload of the chambers, the model of your device, and even on where exactly the refrigerator is located in the kitchen. Understanding the operating principles of compressor and the air circulation system will help you set up the device so that it works efficiently and quietly.
In this article we will look at the technical nuances of setting up various models, including single-compressor and dual-circuit systems. You will learn how the position of the thermostat affects its operation evaporator and why it is important to maintain balance. Proper adjustment will extend the life of the motor and ensure the safety of your supplies.
Optimal temperature standards for different compartments
To ensure food safety, it is necessary to strictly adhere to the recommended temperature ranges. In the main refrigerator compartment, the temperature should be maintained between +2 and +5 degrees Celsius. It is in this range that the growth of bacteria slows down, but the products do not freeze, maintaining their structure and taste. If you set the value below +2, you risk freezing vegetables, and above +5, you will speed up the spoilage of meat and dairy products.
The freezer requires more stringent conditions. The standard value is -18 degrees and below. At this temperature, most microorganisms completely cease their vital activity, which allows food to be stored for months. Modern models Atlant often are equipped with a quick freezing function, which temporarily lowers the temperature to -24 degrees, but constantly maintaining this mode does not make sense due to the high load on unit.
It is important to take into account the distribution of cold inside the chamber. In defrosting refrigerators, the temperature at the back wall is always lower than at the door. Therefore, the shelves near the wall are designed for storing products that require strong cooling (meat, fish), and it is better to put drinks and sauces on the door that do not spoil quickly. drip system During defrosting, the temperature at the back wall is always lower than at the door. Therefore, the shelves near the wall are designed for storing products that require strong refrigeration (meat, fish), and it is better to place drinks and sauces that do not spoil quickly on the door.
⚠️ Attention: If your refrigerator is not equipped with an electronic display, but only a mechanical regulator, remember that the numbers on the handle (from 1 to 7) do not mean degrees. These are symbols of cooling power, where 1 is the minimum cold, and 7 is the maximum frost.
Setting a mechanical thermostat
Most classic models Atlant, such as series 45, 48 or 62, are equipped with a mechanical regulator. This is a round knob with divisions, usually located inside the refrigerator compartment or on the top panel. The principle of operation is simple: by turning the knob, you change the pressure in the capillary tube, which causes the compressor to turn on more often or less often.
For normal operating conditions (temperature in the kitchen is about +20...+22°C), the optimal position of the knob is at mark "3" or "4". This is the golden mean, in which the refrigerator operates normally, managing to gain cold, but not working without interruption. If you turn the knob to “6” or “7”, the compressor will work almost continuously, trying to achieve coldness that is unattainable in normal mode, which will lead to overheating.
Seasonality plays an important role when setting up the mechanics. In winter, when the room is cool, the power can be reduced. In summer, when it’s hot, the load should be increased a little, but not to the maximum. If you notice that an ice crust appears on the products, it means that the mode is too powerful, and the knob needs to be turned towards lower values.
☑️ Checking the mechanics settings
Particular attention should be paid to models with two compressors, where each regulator is responsible for its own circuit. It is important here not to confuse which pen is responsible for what, although they are usually labeled or have different color markings. Incorrect setting of one circuit can indirectly affect the operation of another through heat exchange, if the partition does not have high-quality thermal insulation thermal insulation.
Electronic temperature control
More modern series Atlant, for example, XM-4425 or XM-6025, equipped with electronic control. Here you set the exact temperature in degrees, which eliminates guesswork. The control may be located on the outer panel of the door or inside the chamber on the ceiling. The accuracy of such systems is much higher, and the temperature spread is minimal.
For the refrigerator compartment, the standard setting is +3°C or +4°C. The electronics itself will support this mode, turning the compressor on and off based on sensor signals. It is recommended to set the freezer to -18°C. The advantage of electronics is that it can compensate for voltage surges and changes in external temperature, operating in an economical mode.
If you see flashing numbers or indicators on the display, this may indicate a malfunction or defrost. In some models, when turned on for the first time or after a long period of inactivity, it takes time (up to 24 hours) for the system to reach the specified mode. You should not load the camera with food at this time, as this will disrupt the calibration sensors.
The influence of external factors on the operation of the refrigerator
The room temperature directly affects how many degrees the refrigerator needs to be adjusted to. If the kitchen is located on the sunny side or near the stove, the ambient temperature can rise significantly. In such conditions, the refrigerator requires more energy to remove heat through the condenser.
In the summer, when the apartment is hot, even at the medium setting the refrigerator can work more intensely. However, you should not immediately turn the regulator to maximum. It is better to ensure a flow of fresh air to the rear radiator grille. Pushing the refrigerator tightly against the wall worsens heat transfer, causing the motor to wear out.
In winter, the situation is the opposite. If the refrigerator is located in an unheated area (for example, on an insulated balcony, although this is not recommended by the instructions), the mechanical thermostat may simply not turn on, since it is “warm”. In such cases, it is necessary to either heat the thermostat zone (special heater) or set the knob to the maximum power position to force the cycle to start.
| Condition | Recommended position (Mechanics) | Recommended t° (Electronics) | Note |
|---|---|---|---|
| Standard conditions (+20°C) | 3 - 4 | +3...+4°C | Basic mode |
| Hot summer / Product loading | 4 - 5 | +2...+3°C | Temporary boost |
| Winter / Empty chamber | 2 - 3 | +4...+5°C | Resource saving |
| Quick freezing | Freezing mode | -24°C (temporarily) | No more than 24 hours |
⚠️ Attention: Do not install the refrigerator near heating appliances or in direct sunlight. Even the correct temperature setting will not save the compressor from overheating if ventilation conditions are violated.
Setting features for different Atlant models
Model range Atlant is extensive, and configuration approaches may vary. Single-compartment refrigerators (refrigerator compartment only) are adjusted solely by the temperature inside this chamber. Here it is important to prevent food from freezing at the back wall, so the regulator is often kept at 2-3 notches.
Two-chamber models with one compressor are the most common type. Here the temperature is regulated only in the refrigerator compartment, and in the freezer it depends on the operation of the main circuit automatically. If the refrigerator compartment is warm, then the freezer will not be cold enough. Therefore, the adjustment is always carried out in the upper chamber, using a thermometer for control.
Models with the system No Frost require a special approach. Air circulates in them forcibly, and the temperature is equalized throughout the entire volume. Here you cannot set the maximum mode, as this will lead to rapid drying of the products (moisture sublimation). For No Frost, the average setting is optimal, providing stable, but not extreme cold.
Why do two-chamber refrigerators have one handle?
In such models, one compressor drives the refrigerant through both circuits. The thermostat is located in the refrigerator compartment. When the desired temperature is reached there, the compressor turns off and cooling stops in the entire refrigerator. Therefore, by adjusting the top, you automatically adjust the bottom.
Typical mistakes when adjusting cold
One of the most common mistakes is an attempt to “speed up” the cooling of just loaded products by turning the knob to the maximum. This will not make the food freeze faster, but it is guaranteed to overload motor-compressor. Products are cooled at a certain speed, depending on the physics of the process, and not on the desire of the user.
Another mistake is ignoring the sounds of a running unit. If when set to “3” the refrigerator hums and crackles, and when set to “5” it goes silent (or vice versa), this may indicate a malfunction of the thermostat or a problem with the refrigerant. Normal operation is accompanied by cyclic turning on and off.
Also, users often forget to check the tightness of the door after changing the settings. At lower temperatures, materials may shrink, and if the seal is old, the seal will be compromised. This will lead to the formation of ice and the constant operation of the compressor, which will try to compensate for the loss of cold.
Frequently asked questions (FAQ)
Why does ice freeze on the back wall in the Atlant refrigerator?
This is a normal process for a drip defrosting system. Water flows down the wall into a groove and evaporates. However, if a thick coat of ice forms, you may have set the temperature too low (the knob is at 6-7) or the door seal that lets in moist air is damaged.
How can you tell if the temperature in the refrigerator is insufficient?
Use a regular outdoor thermometer, placing it in a glass of water on the middle shelf. If after 6-8 hours it shows above +5°C, and the knob is not at the minimum, it may be necessary to top up with freon or replace the thermostat.
Is it possible to place the Atlant refrigerator on the balcony?
The instructions do not recommend operation at temperatures below +10°C or above +32°C. On an unheated balcony in winter, the oil in the compressor will thicken, and the motor will burn out when starting, and in summer it will overheat. If there is no other way out, the balcony must be insulated.
What does a flashing temperature indicator mean?
Flashing usually signals an increase in the temperature inside the chamber above the permissible limit. This happens when you first turn it on, after defrosting, or when the door is not tightly closed. If the indicator does not stop flashing after the temperature has set, check the tightness.
