After completing the defrosting procedure and thoroughly washing the chambers your two-chamber refrigerator a critical moment comes - the correct start and adjustment of the temperature regime. Many equipment owners Atlant make the mistake of believing that it is enough to simply plug in the device and set the regulator to the middle position, however, the process of entering the operating mode requires a more careful approach to preserve the compressor.
Incorrect initial settings can cause the food in the main compartment to spoil due to too high a temperature, or cause excessive ice to form in the freezer if the thermostat does not operate correctly during the first cooling cycle. It is important to understand that thermostat after a long period of inactivity it needs stabilization, and the refrigerant must be evenly distributed throughout the system.
In this article we will analyze in detail the algorithm of actions for models with mechanical and electronic control, explain the physical processes occurring inside the unit during the first hours of operation, and point out the nuances that will help extend the service life of your refrigeration equipment. Compliance with the sequence of actions ensures that the equipment reaches its nominal values exactly as intended by the plant engineers.
Physics of the process: why you can’t rush to load
Immediately after turning on the compressor, the refrigerant begins to circulate through the system, but to achieve nominal temperature it takes time inside the cameras. In two-chamber models Atlant with one compressor, the cold first accumulates in the evaporator of the freezer, and only then the cooled air begins to actively circulate in the refrigeration compartment.
If you load the products immediately, the thermal the inertia of a large volume of food will force the compressor to work without stopping for many hours, which creates an extreme load on the motor-compressor and can lead to its overheating or even failure. Heat transfer in an empty chamber it happens much faster and safer for the technical components of the unit.
In addition, the walls of the chambers and internal shelves must also cool down to operating temperature, since plastic and metal have their own heat capacity and will initially give off heat to the air, interfering with rapid cooling. Only after the empty refrigerator has worked for the allotted time can you begin gradual loading, monitoring the thermometer readings.
⚠️ Attention: It is strictly forbidden to load warm or hot foods into a refrigerator that has just been defrosted and turned on. This will cause a sharp jump in temperature, the formation of condensation on the internal walls and force the compressor to work in overload mode, which reduces the service life of the equipment.
How long do you need to wait?
Depending on the ambient temperature (temperature in the room) and the volume of the chamber, the primary cooling of an empty two-chamber refrigerator Atlant takes from 2 to 4 hours. Complete stabilization of the temperature at all points of the volume can take up to 12 hours.
Action algorithm for models with mechanical control
In most models Atlant with mechanical control, the thermostat is a rotary knob with a digital designation from 1 to 7 (or from Min to Max). After defrosting and turning on the device, it is necessary to set the regulator knob to the middle position, usually this is a number 3 or 4, which corresponds to a temperature of about +4...+5°C in the refrigerator compartment.
It is not recommended to immediately turn the knob to the maximum (number 7), trying to speed up the cooling process, as this can lead to freezing of products to the rear wall and the formation of a “snow coat” even in No Frost systems if defrosting is not operating correctly. Thermostat Thermostat
After setting the handle to the middle position, let the refrigerator run idle for at least 2-3 hours. During this time, the compressor must make several cycles of turning on and off, which indicates the correct operation of the automation and the achievement of the specified temperature parameters inside the chambers.
☑️ Initial start of the mechanics
Setting up electronic control and display
Modern two-chamber refrigerators Atlant are often equipped with an electronic control unit with a digital display, where the temperature can be set with an accuracy of a degree. Immediately after turning on the power, the current indicators may flash on the display or the alarm indicator will light up, which is a normal signal that the chambers are still warm.
To set the optimal mode, use the control buttons (often indicated as Temp or up/down arrows) and set the value to +3°C or +4°C for the refrigerator compartment and -18°C for freezer. Electronics refrigerator itself optimizes the operation of the compressor and fans to achieve these values in the most energy-efficient way.
Some models have a “Super Freeze” or “Quick Cooling” function, which can be activated for a short time (3-5 hours) immediately after defrosting to speed up the temperature rise, but do not forget subsequently, manually turn off this mode so as not to overfreeze the food and not waste extra electricity.
Table of recommended temperature conditions
For proper storage of different groups of products, it is important to understand what temperature should be maintained in different zones of the refrigerator. Below is a reference table that will help you set Thermostat depending on what you plan to fill the chambers with in the first place.
| Storage area | Recommended temperature | Position regulator (mechanical) | Shelf life (approximate) |
|---|---|---|---|
| Freezer compartment | -18°C and below | 5-6 (or -18 on the display) | Up to 12 months |
| Shelf for meat/fish | 0...+2°C | Freshness zone | 2-3 days |
| Middle shelves | +3...+5°C | 3-4 (standard) | 3-5 days |
| Door shelves | +5...+8°C | Depends on the load | 1-2 days (milk) |
It is worth noting that the position of the regulator (numbers 1-7) does not mean the temperature in degrees, but only indicates the intensity of the compressor. Number 1 is the least cooling, number 7 is the maximum. The exact temperature in degrees is shown only by models with digital display or an external thermometer.
Typical errors when starting up for the first time
One of the most common mistakes is ignoring the settling time. After defrosting and washing, moisture remains inside the refrigerator, and the refrigerant in the system may have shifted. If you turn on the unit immediately and start loading it, this can lead to water hammer in the compressor or incorrect readings from the humidity sensors.
Also, users often forget to check the position of the refrigerator itself. After defrosting, the unit could be moved, and if it is not level, the door may not fit tightly, or condensation will flow not into the gutter, but onto the floor. Casing distortion disrupts air circulation and the operation of the defrosting system.
- 🔌 Forgot to check the density seals fit after washing, which causes warm air to enter the chamber.
- ❄️ We set the regulator to minimum (1), wondering why the food was spoiling, although the compressor was working.
- 🚪 They often opened the door during the first hours of operation, disrupting the temperature rise process and forcing the motor to work without rest.
Time to reach operating mode and control
Full return of a two-chamber refrigerator Atlant to operating mode after defrosting takes an average of 4 to 6 hours, but the final stabilization of temperature at all points in the volume can last up to a day. At this time, you should not load the chamber completely; it is better to add products gradually, in small portions.
You can control the process not only by feeling, but also using a household thermometer placed on a glass of water on the middle shelf. This will give an objective picture of how accurately thermostat keeps the specified range and whether there are any significant deviations that could arise after a long period of inactivity.
If, after 6-8 hours of operation at medium settings, the refrigerator does not cool properly or, conversely, freezes food tightly, you may need calibration or checking the tightness of the circuit, since hidden defects could appear after defrosting.
⚠️ Attention: If after 12 hours of operation the refrigerator compressor does not turn off at all, and the temperature in the chambers does not drop below +10°C, immediately unplug the device. This may indicate a freon leak or a compressor malfunction, and further operation is useless and dangerous.
Features of loading products after setup
When you are convinced that the temperature in the chambers has stabilized, you can start loading. Start with foods that require less strict temperature conditions, and arrange them so as not to block the ventilation openings, especially in models with the system No Frost or Frost Free.
Do not overcrowd the refrigerator on the first day. A sharp increase in thermal mass will require the compressor to operate at its maximum capacity for a long time. It is better to fill the volume gradually throughout the day, giving the system cooling time to cope with heat influx.
Check that the food does not touch the back wall of the refrigerator compartment, where the evaporator is located. Contact with a cold surface can lead to local freezing of the contents of bags or cans, even if the overall temperature in the chamber is positive.
What should you do if an extraneous sound appears after setting up?
After defrosting and turning on for the first time, gurgling or crackling sounds may be heard. This is normal: the refrigerant is redistributed, and the plastic elements expand or contract due to temperature changes. If the sound resembles a knocking, grinding or humming becomes unbearable, check whether the pipes are touching the back of the wall, and make sure that the refrigerator is stable.
Is it possible to speed up cooling with a fan?
Theoretically, by directing the fan into the open chamber of an empty refrigerator, you can quickly cool down the internal volume. However, manufacturers Atlant do not recommend doing this, as this can lead to dust and moisture getting on the electrical contacts and disrupt the natural heat transfer process calculated by engineers.
Do you need to change the position of the regulator in winter?
If the refrigerator is in in an unheated room or in the kitchen, where in winter the temperature drops below +16°C, the mechanical thermostat may not work correctly (the compressor will rarely turn on). In such cases, you may need to set the knob to lower values (5-6) or use a special winter mode, if provided by the model.
Following these simple but important rules will allow your two-chamber refrigerator Atlant quickly return to full operation after defrosting. Correct temperature setting is the key to the long life of the compressor and maintaining the freshness of your products for a long time.
