After purchasing a new refrigerator or turning it on again after transportation, it is extremely important not only to wait until the mode is reached, but also to set the temperature parameters correctly. Optimal setting directly affects the service life compressor and quality of food storage. If you have just connected the unit to the network, rushing to select modes can lead to overloading the system.
In two-chamber brand models Atlant the control system may differ depending on the type of compressor and the year of manufacture of the device. Modern electronic panels require precise calibration, while mechanical controls operate like a thermostat. Understanding the operating principle of your model will allow you to avoid common mistakes, such as the formation of an ice coat or insufficient cooling.
In this material we will analyze in detail the algorithm of actions for various series of equipment, explain the physics of the cooling process and point out nuances that even experienced users often forget about. A competent approach to the initial setup will save energy and keep your supplies fresh.
Preparing for the first start-up and entering the mode
Before setting specific numbers on the display or turning the thermostat knob, you need to make sure that the unit is physically ready for operation. After delivery, the equipment cannot be turned on immediately, especially if it was transported at low temperatures or in a horizontal position. The oil in the compressor must drain into the crankcase, and the refrigerant must stabilize.
After the device has stood for the required time (usually from 2 to 4 hours, but it is better to wait longer), it is connected to the network. At this point temperature mode should be set to medium values or to the “Off” position if the instructions require pre-warming the electronics. Starting an empty refrigerator at maximum power may cause false sensor signals.
⚠️ Attention: If the refrigerator has been turned off for a long time, the first operation of the compressor may be accompanied by an unusual hum. This is normal, but if the noise does not subside after 15 minutes, check the stability of the legs and the absence of contact with the furniture.
The initial entry into cooling mode takes different times. For an empty chamber this may take 4 to 8 hours. During this period, you should not open the doors often, as heat exchange is disrupted, and thermostat cannot correctly read the temperature of the air inside the volume.
Differences in control: Mechanics versus Electronics
All two-chamber models Atlant are divided into two large groups by type of management. In mechanical models, you will see a round regulator with marks or numbers from 1 to 7 (or Min/Max). There are no exact degrees here, only conditional cooling intensity. Electronic models are equipped with a display on the outer panel of the door, where you can set the exact temperature for each chamber separately.
In mechanics, the operating principle is simple: turning the knob changes the moment at which the thermostat contacts open. The higher the number, the lower the temperature must drop for the compressor to turn off. In electronics, the process is monitored NTC sensors, which transmit signals to the control board. This allows you to maintain the climate with an accuracy of 0.5 degrees.
Users of electronic panels should be more careful when turning it on for the first time. Often, the quick freeze mode or demo mode is activated by default and needs to be disabled. Mechanical regulators are more “rough”, but also less likely to fail due to power surges.
Why are the numbers on the mechanics not equal to degrees?
The numbers on a mechanical thermostat (1-7) do not indicate degrees Celsius, but the degree of tension of the thermostat spring. The number 7 means that the compressor will work almost non-stop until the temperature becomes extremely low, which can lead to freezing of the evaporator.
Optimal temperature values for a two-chamber system
To ensure safe storage of products and proper operation of the compressor, it is necessary to set the parameters recommended by the manufacturer. In the refrigerator compartment, the ideal range is considered to be from +2 to +5 degrees Celsius. In the freezer, especially if you are planning long-term storage, the temperature should not exceed -18 degrees.
If you set the temperature in the refrigerator compartment too low (for example, +1 or 0), food may freeze, and a thick layer of ice will form on the back wall even in No Frost systems due to condensation. Too high a temperature (+7 and above) promotes the growth of bacteria.
The following modes are relevant for the freezer:
- 🧊 -18°C —standard mode for long-term storage of frozen foods (meat, fish, vegetables).
- ❄️ -24°C —fast freezing mode (Super Freeze), activated temporarily for fresh products.
- 🌡️ -6°C —temperature for short-term storage or “Vacation” mode in some models.
The upper shelves are always warmer than the lower ones. Therefore, it is better to place perishable products closer to the back wall and at the bottom.
| Storage area | Recommended temperature | What to store | Shelf life (approximate) |
|---|---|---|---|
| Freezer compartment | -18°C and below | Meat, fish, semi-finished products | up to 12 months |
| Bottom shelf of the refrigerator | +2..+4°C | Raw meat, fish, milk | 1-3 days |
| Middle shelves | +4..+6°C | Ready meals, sausages, cheese | 3-5 days |
| Door shelves | +7..+9°C | Sauces, drinks, eggs | depends on the product |
Instructions for setting up a mechanical thermostat
Owners of models with mechanical control (KShD, KXM series and many older models Atlant) need to focus on the position of the handle. Usually it is located inside the refrigerator compartment, at the top left or right, or on the top panel of the case.
After turning on the empty refrigerator, set the regulator to the middle position (usually number 3 or 4). Let the unit operate in this mode for about 5-6 hours. Then load the products and evaluate the results in a day. If food freezes near the back wall, reduce the power (turn counterclockwise). If the milk turns sour quickly, add (clockwise).
The setting process looks like this:
- 🔧 Find the thermostat inside the chamber or on the body.
- 🎛️ Set the knob to “3” (medium).
- ⏳ Wait 6-8 hours of operation without frequently opening the doors.
- 🥛 Check the temperature of the food or use a household thermometer.
Do not immediately turn the knob to maximum (7 or Max). This will force the compressor to work continuously, which after transportation can lead to its overheating and emergency shutdown via the thermal relay.
☑️ Initial start of mechanics
Setting up electronic controls and display
In modern two-chamber refrigerators Atlant with electronic control (XM, XMA series and others with a display) adjustment is made via touch or push-button panels. After turning on the power, the display may not light up immediately or flash - this is the process of system self-diagnosis.
To set the temperature, buttons with the “Refrigerator” and “Freezer” or “Temp” icons are usually used. Pressing the button changes the value on the display. Holding the button for 3-5 seconds often activates additional functions or child lock.
Recommended action algorithm:
- After turning on, wait for the indicators to glow steadily.
- Press the refrigerator compartment setting button and set +4°C.
- Similarly, set the freezer to -18°C.
- If the alarm indicator is on (a red flashing triangle or an exclamation mark), do not be alarmed - it will go out when the temperature inside drops to normal.
⚠️ Attention: In some models with electronics, after a power surge or a long period of inactivity, it may malfunction time on the display. Although this does not affect cooling, for the correct operation of some functions (for example, defrost indication), it is better to set the time according to the instructions.
The electronics allow the use of special modes such as “Vacation” (Eco) or “Super Freeze”. The “Vacation” mode turns off the refrigerator compartment, leaving the freezer to work, which saves energy when you are not at home.
Super Freeze mode and other special functions
Many models Atlant are equipped with a quick freezing function. On mechanics this is a separate button next to the thermostat, on electronics it is the corresponding menu item. When this mode is activated, the compressor works non-stop, ignoring the readings of the refrigerator compartment thermostat, in order to cool the freezer as quickly as possible.
This mode should be used with caution. After turning on a fresh portion of food for freezing, the “Super Freeze” mode should be turned on 2-3 hours before loading (to cool the chamber) or immediately after. But the most important thing is that you need it manually turn off after 24 hours (or wait for automatic shutdown in advanced models). If you forget to do this, the compressor may burn out from overload, and the food in the refrigerator compartment may freeze.
The “Vacation” mode is also worth mentioning. It is useful if you are leaving for a long time. The refrigerator compartment stops cooling (the temperature there rises to +10..+15°C, which prevents the appearance of mold and odor), and the freezer continues to operate normally. This is an ideal setting for saving resources.
Typical errors and troubleshooting
Even following the instructions, users often encounter problems. One of the most common is to install the refrigerator close to the wall or in a niche without gaps. For the correct operation of the heat exchanger (condenser), which is often located on the side walls or behind, an air flow is necessary. If the gaps are broken, the refrigerator will wear out and not reach the set temperature.
Another mistake is loading warm food into the refrigerator that has just been turned on. This creates a huge thermal load. The compressor will work for hours, trying to reduce the temperature, which is extremely undesirable in the first day of operation. Load the food gradually, in small portions.
If after setting the temperature (more than 10-12 hours have passed) the refrigerator does not freeze, and the compressor works constantly or does not turn on at all:
- 🔌 Check the tightness of the door seals.
- 🌡️ Make sure that The thermostat is not set to minimum (1 or Min).
- 🔊 Listen: can you hear the sound of a running motor or the gurgling of refrigerant.
⚠️ Attention: Characteristics and control interfaces may vary slightly depending on the specific modification and year of manufacture of your model. Always check the paper instructions included in the kit, or find the version on the manufacturer's official website using the exact model number.
Questions and answers (FAQ)
How long after switching on can you load products?
It is recommended to wait at least 4-6 hours after the first switch on so that the empty refrigerator reaches operating temperature. Loading warm products before this time will cause the compressor to work with overload.
Why does the red light on the panel light up after turning on?
This is an indicator of increased temperature. It lights up immediately after switching on, since it is still warm inside. The light should go out on its own when the temperature in the chambers reaches the set values (usually after 3-6 hours).
Is it possible to turn on the refrigerator at full power immediately after delivery?
It is strictly not recommended. After transportation, the oil in the compress should be distributed and the refrigerant stabilized. Turning it on to maximum can lead to water hammer in the cooling system. Start with average values.
What to do if ice freezes in the refrigerator compartment?
Most likely, the temperature is set too low (close to 0°C or at the thermostat maximum). Try raising the temperature by 1-2 degrees. Also check if the drainage channel is clogged and if the door closes tightly.
Is it necessary to defrost an Atlant refrigerator with No Frost?
The No Frost system prevents the formation of ice on food and walls, but it is recommended to completely defrost and wash the chamber at least once a year for hygiene and maintenance of the condensate drainage system.
