Keeping food fresh directly depends on how correctly the operating parameters of your refrigeration equipment are set. For owners of Belarusian brand equipment Atlant this issue is especially acute, since the model range covers both old mechanical regulators and modern electronic control systems. Understanding the physical processes of cooling will help avoid spoilage of stocks and excessive consumption of electricity.
Owners often wonder why food in one chamber freezes, while in another, on the contrary, it quickly deteriorates. The answer lies in the uneven distribution of cold and the incorrect position of the thermostat knob. Optimal temperature conditions is a balance between preserving taste and food safety. In this article we will look at how to configure your Atlant refrigerator for ideal operation.
It is necessary to take into account that different models may have their own design features. Old two-chamber units with a drip defrosting system require more careful attention to settings than modern systems No Frost. Let's figure out what are the reference values for different storage areas.
⚠️ Attention: If you have just installed the refrigerator or defrosted it, do not try to immediately set the ideal settings. Allow the equipment to operate for 5-6 hours in standard mode to stabilize the refrigerant in the system.
Standard temperature standards
According to technical regulations and recommendations of household appliance manufacturers, the temperature in the main refrigeration chamber should be maintained in the range from +2 to +5 degrees Celsius. It is under these conditions that pathogenic bacteria multiply slowest, allowing products to remain safe for consumption for a long time. For a freezer, the standard value is -18 degrees and below.
However, if you own a model Atlant with a system No Frost, it is worth remembering the nuances of air circulation. In such units, cold air is pumped by a fan, which can lead to local hypothermia of products standing at the back wall. Therefore average temperature in the chamber it may be slightly higher than that set on the display, but at the walls it will always be lower.
It is important to distinguish between the concepts of “storage temperature” and “freezing temperature”. If the freezer compartment is set to -12 or -14 degrees, this is acceptable for short-term storage, but for long-term freezing of meat and fish, a value no higher than -18°C is required. At higher temperatures, enzymatic processes in products continue, albeit slowed down.
Setting a mechanical thermostat
In most classic models Atlant (for example, the KSh-268, KSh-270 series), control is carried out using a rotary knob located inside the chamber or on the body. The scale usually contains numbers from 1 to 7 (or from Min to Max). Many users mistakenly believe that the number indicates degrees, but this is only the conditional power of the compressor.
The higher the number on the regulator, the more intense the motor-compressor works and the colder it becomes inside. Golden mean for everyday use in the warm season it is usually on division 3 or 4. If you turn the knob to the maximum (6 or 7), the compressor will work almost without stopping, which will lead to freezing of products at the back wall and increased noise.
In winter, when the room is cool, the load can be reduced by moving the regulator to division 2 or 3. This will prevent the unit from turning on too often. However, if the apartment is hot, you may need to shift the setting closer to 5 to compensate for heat gain.
There is a common misconception that the handle needs to be turned sharply. You shouldn’t do this: adjust the position smoothly, giving the system 30-40 minutes to react after each change. Mechanical thermostat has inertia, and you can’t expect instant results.
Electronic unit control
Modern models Atlantequipped with electronic control allow you to set the temperature with an accuracy of degrees. The interface can be represented by LED indicators or a full-fledged display. Here you set exactly the target value, and the “smart” electronics decide when to turn on the compressor.
For the main camera, it is recommended to set the value to +3 or +4 degrees. This is the most versatile mode. If you plan to store a lot of perishable products (meat, fish, dairy products), you can reduce the value to +2°C. For storing drinks and ready-made dishes that do not require strict cold, it is permissible to raise the temperature to +5°C.
In the freezer compartment of electronic models, it is optimal to keep -18°C. The Super Freeze function (usually indicated by a snowflake or the letter F) automatically lowers the temperature to -24°C for several hours before returning to the set values. This mode should only be used when loading a large amount of fresh food.
⚠️ Attention: In electronic models, the indicator on the display may flash after changing the settings. This means that the adaptation process is underway. Do not change the settings again until the display stabilizes; this usually takes about 10-15 minutes.
Some advanced models allow you to independently adjust the temperature in different zones or activate the “Vacation” mode. In the latter case, the main chamber can be turned off or switched to energy-saving mode +15°C while the freezer continues to operate normally.
Table of food storage by temperature zones
Inside the refrigerator, the temperature is unevenly distributed. Knowing the features of air circulation in your Atlanta, you can wisely arrange your supplies. Cold air is heavier than warm air, so it is always colder below than on the upper shelves. The door is the warmest place due to contact with room air when opening.
Below is a table that will help you figure out where and what is best stored to extend shelf life:
| Storage area | Approximate t°C | What to store | Shelf life (approximate) |
|---|---|---|---|
| Top shelf | +5...+7°C | Ready meals, drinks, confectionery | 2-3 days |
| Middle shelves | +3...+5°C | Dairy products, sausages, cheeses, bread | 3-5 days |
| Bottom shelf (above the drawers) | +2...+3°C | Raw meat, fish, semi-finished products | 1-2 days |
| Shelves on the door | +7...+10°C | Sauces, butter, eggs, bottled drinks | Depends on the product |
| Zero zone (Bio Fresh) | 0...+1°C | Fresh vegetables, herbs, chilled meat | up to 10-14 days |
Using this scheme, you will prevent a situation where milk sours faster than expected, and meat loses color. Correct zoning there is no room inside the chamber less important than the overall thermostat setting. Also, do not overcrowd the refrigerator: for effective operation, the cold needs space to circulate.
☑️ Checking the correct loading
Seasonal adjustments and environmental influences
The temperature in the room where the refrigerator is located directly affects the frequency of the compressor switching on. In summer, when the apartment is +25...+28°C, equipment has to work more intensely. During this period, a slight adjustment of the regulator may be required in the direction of increased cold, especially if you notice that food has begun to deteriorate faster.
In winter, the situation is the opposite. If the refrigerator is located near a heating radiator or in a kitchen with a gas stove, heat gain can be significant even in winter. However, if the unit is located in an unheated corridor or on a balcony (which is only allowed for climate class SN or T), the oil in the compressor may thicken and it will stop starting.
For models Atlant with one compressor this is typical dependence: the colder it is in the freezer, the colder it is in the refrigerator compartment. Therefore, in winter, when the house is cool, the thermostat knob often has to be switched to weaker mode (numbers 2-3) so that vegetables do not freeze in the main chamber.
⚠️ Attention: Do not install the refrigerator close to the wall or furniture. A gap of at least 5-7 cm is necessary to remove heat from the condenser (grids at the back). Violation of this rule leads to overheating and incorrect operation of the temperature sensor.
In the off-season, when the heating is not yet (or no longer) working, and it is damp and cool outside, watch out for the formation of condensation. During such periods, humidity is high, and incorrect settings can lead to freezing of the “coat” even in systems with automatic defrosting.
Diagnostics of temperature problems
How can you tell if the refrigerator is not working correctly? The first sign is a change in the consistency of the products. If bread freezes in the main chamber or milk turns into an icy porridge at the back wall, the temperature is too low. If the butter has become soft, like plasticine, and the kefir has begun to bubble, the cold is not enough.
Frequent turning on and off of the compressor (a cycle of less than 10-15 minutes) also indicates a problem. This may be caused by a malfunctioning thermostat, a freon leak, or a leak in the door seal. In such cases, simply resetting the handle will not help - you will need repair or replacement of parts.
What to do if the refrigerator is too cold?
If the food freezes and the regulator is at a minimum, try checking the door seal. If it does not fit tightly, warm air enters, causing the compressor to work harder, but due to poor circulation, there may be ice in some areas and heat in others. Also check that the ventilation holes inside the chamber are not blocked by food.
Another important aspect is defrosting. Even modern systems No Frost require prevention. If the evaporator becomes overgrown with ice, heat exchange is disrupted. In models with manual defrosting (“crying” evaporator), a layer of ice more than 5 mm thick significantly impairs operating efficiency.
Frequently asked questions about settings (FAQ)
Why does ice form on the back wall of the Atlant refrigerator?
This may be a sign that the temperature is set too low (knob on 6-7), or the defrost sensor is faulty. Ice also appears if you put hot food in the chamber or frequently open the door to let in moist air. In drip systems, slight ice formation and drainage is a normal operating process.
What temperature should be set in the freezer for long-term storage of meat?
For long-term storage (more than 1 month), it is recommended to set the temperature to -18°C or lower. At -12°C, meat can be stored for no more than 2-3 weeks, after which it begins to lose taste and structure.
Is it possible to turn off the freezer and leave only the refrigerator working?
In most models Atlant with one compressor, it is impossible to completely turn off the freezer, since the refrigerant circulates along both circuits. However, many electronic models have a “Vacation” function or the ability to separately regulate the temperature of the freezer, raising it to -5...-8°C to save energy if it is empty.
Does the amount of food in the refrigerator affect the temperature?
Yes, it does. An empty refrigerator heats up faster when the door is opened. A full chamber (but not crammed!) holds the cold better, since the products act as cold accumulators. However, air must circulate between the products.
