Purchasing a modern two-chamber unit from a Belarusian manufacturer often becomes a solution to the problem of storing food for a large family. Two-compressor system ensures independent operation of the refrigeration and freezer chambers, which significantly increases cooling efficiency and reduces energy consumption. Correct initial setup is a critical stage on which the service life of compressors and the quality of maintaining the freshness of products depend.
Many owners make the mistake of relying solely on the factory parameters set at production. However, operating conditions in different apartments may differ significantly: ambient temperature, frequency of door openings and shelf loading density require individual calibration. In this article, we will look in detail at how to correctly set the temperature regime, activate special functions and avoid common mistakes when starting up your Atlanta for the first time. Immediately after delivery and installation of the unit at your permanent location, do not rush to plug it into the network. Compressor oil needs time to drain into the crankcase, especially if the equipment was transported in a horizontal position. Typically, manufacturers recommend waiting from 2 to 4 hours, but in winter it is better to increase this interval to 6-8 hours in order to avoid water hammer and failure of the piston group.

Primary preparation and placement of equipment
The successful operation of any refrigeration equipment directly depends on the quality of its installation in the room. Two-compressor models Atlant are sensitive to condenser overheating, so maintaining thermal clearances is a mandatory requirement. If the rear grille is pressed tightly against the wall or covered by furniture, the efficiency of heat transfer will drop sharply, which will lead to longer operating times for the motors and higher electricity bills.
It is important to ensure free circulation of air around the cabinet. The minimum distance to the rear wall should be at least 5-7 cm, and to the side walls - about 5 cm. The floor on which the equipment is installed must be flat and hard. If the floor is uneven, use the adjustable feet on the bottom of the cabinet to level it, otherwise the doors may not seal tightly against the seal, causing ice to freeze.
⚠️ Warning: Do not install the refrigerator near heaters, radiators, or in direct sunlight. Increased ambient temperatures force compressors to work almost non-stop, which reduces their service life.
Before turning on, conduct a thorough inspection of the internal space. Remove any shipping locks, if any, and remove any plastic wrap from shelves and drawers. Wipe the internal surfaces with a soft cloth soaked in a weak solution of soda or a specialized plastic care product to eliminate the smell of a new product.
Adjusting the temperature in the refrigerator compartment
The central control element in most models Atlant is a mechanical or electronic temperature controller. In mechanical systems, it is represented by a rotary knob with divisions from 1 to 7 (or from Min to Max), usually located inside the chamber or on the top panel. Electronic control allows you to set exact values in degrees Celsius through the display on the door.
The optimal temperature for storing most products in the main chamber is considered to be from +3 to +5 degrees Celsius. When setting the regulator to the average value (usually division 3 or 4 on the mechanics), a balance is ensured between food safety and operating efficiency. If you have loaded the chamber with a large amount of warm products, you can temporarily increase the cooling, but do not forget to return the settings back.
You should not set minimum temperature values unless absolutely necessary. Working in maximum freezing mode leads to overdrying of food, loss of moisture and vitamins. In addition, constant operation at the limit of capabilities reduces the service life of door seals and the compressor itself compressor.
| Regulator position | Approximate temperature | Recommended use |
|---|---|---|
| 1 (Min) | +8...+10°C | Minimum load, economy mode |
| 3-4 (Average) | +3...+5°C | Daily operation, standard load |
| 6-7 (Max) | 0...+2°C | Fast cooling, large load |
| 0 (Off) | - | Switching off the refrigerator compartment |
If your model has a separate zone freshness or zero chamber, its setting can be done independently. In such compartments, the temperature is maintained at about 0 degrees, which is ideal for storing fresh meat, fish and vegetables that you plan to cook in the coming days.
Setting the freezer and super freezing functions
The freezer in two-compressor refrigerators Atlant works independently of the main compartment, which allows you to customize it modes separately. For long-term storage of frozen foods, the optimal temperature is -18 degrees Celsius or lower. In this mode, microorganisms do not multiply, and the products retain their properties for up to 12 months.
The function "Super freezing" (often referred to as Fast Freeze or snowflake) is intended for quick freezing of fresh products. When this mode is activated, the second compressor starts working continuously, lowering the temperature in the chamber to -24...-26 degrees. This allows you to freeze the product quickly, preventing the formation of large ice crystals that destroy the structure of the tissues of meat or vegetables.
Why is it important to freeze quickly?
During slow freezing, large ice crystals form inside the cells of the product, which break the cell walls. After defrosting, such a product loses juice, becomes flabby and loses its taste. Quick freezing creates many small crystals, preserving the structure.
You cannot always use the intensive freezing mode. This leads to increased wear and tear on equipment. Activate the function 2-3 hours before loading a large batch of fresh produce and be sure to turn it off after 24 hours (some models turn it off automatically). Long-term operation in extreme mode can lead to food freezing to the shelves and making it difficult to open the door.
⚠️ Attention: Do not load large quantities of warm food into the freezer. A sharp jump in temperature will cause the compressor to wear out, and steam from the products will turn into a snow coat on the evaporator.
Management of the No Frost and defrosting system
Most modern two-compressor models Atlant equipped with a system No Frost (or partial, Full No Frost). The main feature of such devices is that there is no need for manual defrosting. The built-in timer periodically starts the evaporator heating element, which melts the ice and the water evaporates. The user only needs to monitor cleanliness and hygiene.
Despite the automation, there are operational nuances. The No Frost system actively dries the air inside the chambers. Therefore, products that are not packaged in containers or film will quickly air out and lose moisture. Use airtight packaging for all products, especially cheeses, sausages and ready meals.
If you notice that a layer of ice or a snow coat has formed in the freezer, this may indicate a malfunction. Most often, the problem lies in a loose door fit, damage to the seal, or a malfunction of the defrost sensor. In such cases, a check of the technical condition is required, and not just another defrost.
For models with a drip defrosting system in the refrigerator compartment, it is important to periodically check the drainage hole. It is located on the back wall inside the camera. If it becomes clogged with crumbs or mold, water will start to flow onto shelves and food rather than into the evaporator. Clean the hole with a special soft brush or cotton swab as needed.
Economical operation and additional functions
The two-compressor circuit itself is more energy efficient, since each motor turns on only when a specific camera needs it. However, there are additional ways to optimize your Atlanta. For example, the “Holiday” function allows you to switch the refrigerator compartment to an economical operating mode, preventing the appearance of odors and mold while the main compartment is not in use.
When the “Vacation” mode is activated, the temperature in the refrigerator compartment rises to +10...+15 degrees, which is not enough for storing food, but enough to prevent spoilage closet The freezer continues to operate normally. This is an ideal solution for long business trips or the summer season.
☑️ Energy efficiency check
It is also worth paying attention to the location of the products. Cold air circulates inside the chambers, and if the shelves are packed too tightly, the circulation is disrupted. The compressor will run longer to cool remote corners. Leave small gaps between the food and the back wall.
Keep the condenser grill at the back of the refrigerator clean. Dust that accumulates on it over the years acts as a heat insulator, preventing heat removal. Regular (every six months) cleaning of the grill with a vacuum cleaner or dry brush can reduce energy consumption by up to 10-15%.
Diagnostics and typical configuration errors
Even a properly configured refrigerator can cause inconvenience if you ignore basic operating rules. Users often complain that the equipment “freezes poorly” or “freezes too much.” In 80% of cases, the problem lies not in a breakdown, but in an incorrectly selected temperature mode or incorrect loading.
If the food in the refrigerator compartment freezes, check whether it is adjacent to the back wall. In drip systems, the evaporator is located there, and the temperature at the wall may be lower than the overall temperature in the chamber. Move items closer to the center of the shelf.
⚠️ Warning: If your refrigerator is making loud knocking, gurgling, or humming sounds that were not present before, do not ignore it. Perhaps the geometry of the case was broken during transportation or the compressor shifted.
Another common mistake is installing the refrigerator on a soft floor covering (carpet, thick linoleum) without a hard backing. This may cause vibration and noise. Use a special anti-vibration stand or make sure that the legs are firmly on the base.
If a persistent unpleasant odor appears that cannot be eliminated by washing, try using special odor absorbers or folk remedies (activated carbon, soda, citrus peels). The smell can be absorbed into the plastic elements of the interior, so it is better to carry out preventive maintenance regularly.
Frequently asked questions (FAQ)
How long should the Atlant refrigerator sit after transportation in winter?
If the refrigerator was transported at subzero temperatures, it must be allowed to warm up to room temperature within 3-4 hours before turning on. This is necessary so that the condensation formed inside the electronics evaporates, and the oil in the compressor becomes liquid enough for normal operation.
Why is a two-compressor refrigerator louder than a single-compressor one?
In fact, two-compressor models often operate quieter, since each compressor has less power and turns on less often. However, if you hear noise, check to see if the cabinet is touching furniture or walls. Also, the noise level depends on the model of the compressor and the quality of the installation.
Is it possible to turn off one of the chambers in a two-compressor refrigerator?
In most models Atlant with mechanical control, you can independently turn off the refrigerating or freezer compartment by moving the corresponding control to the “0” or “Off” position. On electronically controlled models, this function may or may not be available through a menu. Read the instructions for the specific model.
How often do you need to defrost an Atlant refrigerator with the No Frost system?
The No Frost system does not require defrosting to remove ice, as this happens automatically. However, sanitary defrosting and washing are recommended to be carried out 1-2 times a year to remove bacteria, mold and odors, as well as to check the cleanliness of the drainage channels.
