When choosing a new household appliance or when trying to find compatible spare parts for an existing unit, users are often faced with an incomprehensible set of letters and numbers on the device nameplate. The model range of the Belarusian plant Atlant is huge, and each serial number carries encoded information about the technical characteristics of the device. Understanding this logic allows you not only to find out the model name, but also to determine the type of defrosting system, climate class and even the type of refrigerant used.
In this article we will analyze in detail the structure of the factory markings so that you can determine the key parameters of your equipment without the help of a consultant. Knowing what is hidden behind each number in the code will help you avoid mistakes when ordering spare parts or choosing an analogue. This is especially true when the original sticker on the case is damaged or worn out by time, and you have to rely on passport data or remnants of information.
Modern coding standards adopted at the factory are strictly regulated, but they have their own characteristics for different series and years of production. Once you understand the algorithm, you can easily read technical data sheets and understand exactly how one model differs from another, even if visually they look identical. This knowledge is the first step to competent operation and maintenance of your kitchen appliances.
The structure of the factory marking and its meaning
The main identifier of any refrigeration equipment Atlant is an alphanumeric code, which usually begins with a prefix. In the vast majority of cases, you will come across the designation HM, which literally stands for “Refrigerator Freezer”. It is with these two letters that the decoding path begins, and they indicate that the device belongs to the class of combined equipment.
Immediately after the letters are numbers, each of which occupies a strictly defined position and carries a specific semantic meaning. The first number after the letters indicates the total amount of usable space, the second indicates the number of chambers, and the third tells the consumer about the type of defrosting system. The remaining characters in the code refer to design features, design and modifications.
⚠️ Attention: Do not confuse the model number (for example, XM 4008-000) with the serial number of the device. The serial number is a unique identifier for a specific instance, used for warranty, while the model code describes the characteristics of the entire series.
It is important to note that there are models that are not dual-chamber. For example, if you see a code starting with MX, this means that you have a free-standing freezer. For them, the code structure will be slightly different, since the main emphasis is on the parameters of the freezer. There are also single-chamber refrigerators labeled as X, however, in the modern model range they are represented less widely.
Deciphering the first digits: volume and number of chambers
The first digit in the numeric part of the code (coming immediately after the letters XM) is an indicator of the dimensions and usable volume of the device. The factory uses a scale from 1 to 9, with each value corresponding to a specific liter range. This allows you to quickly navigate the size of the unit without resorting to measuring with a tape measure.
The second digit is responsible for the configuration of the internal space. It tells you how many independent compartments the device has. For two-chamber models, this is a critically important parameter, since it determines the presence of a separate freezer with its own evaporator or the presence of a common cooling system.
- 📏 The number 1 indicates a volume of up to 100 liters - these are compact solutions for small kitchens or offices.
- 📏 The number 2 indicates a range from 100 to 170 liters, which is the standard for narrow models.
- 📏 The number 3 indicates a volume from 170 to 250 liters - the most common class for medium-sized families.
- 📏 The number 4 and above means a volume of over 250-300 liters, typical for wide and tall models.
If the second digit in the code is 2, this means a classic two-chamber design with two doors. If it is there 1, in front of you is a single-chamber refrigerator. There are also three-chamber modifications (digit 3), which are equipped with an additional freshness zone or a separate freezer compartment in the upper part. Understanding this logic helps to immediately weed out unsuitable options when searching for spare parts.
Defrost systems: what the third number hides
The third position in the marking is one of the most important for the user, as it determines the comfort of operation and the need for manual maintenance. This is where the answer to the question lies: will you regularly have to pick up a knife to chop ice or will the system do it automatically.
The value of the number 0 or 1 in this position indicates the presence of the system No Frost (or “Complete No Frost”). This means that both the refrigerator and freezer compartments are equipped with forced air circulation technology, which eliminates the formation of ice. In such models, moisture is removed outside the chambers through the drainage system.
If the third digit is 2 or 3, this indicates a classic drip defrosting system (“Crying evaporator”) in the refrigerator compartment and manual defrosting in the freezer. In such devices, condensate on the back wall of the refrigerator freezes, and then, when the compressor is turned off, flows into a groove. The freezer will have to be defrosted manually about once every six months.
⚠️ Attention: Models with a drip system (number 2 or 3) require periodic checking of the drainage hole. If it becomes clogged with crumbs or ice, water will begin to accumulate at the bottom of the refrigerator and flow out.
There are also transitional options where there is No Frostin the freezer and a drip system in the refrigerator compartment. In marking Atlant such nuances are often reflected in subsequent digits of the code or in the name of the series, but the basic third digit sets the main vector of the technology. Modern models are characterized by a desire for a complete absence of ice, so codes with “twos” are becoming increasingly rare in premium lines.
Design features and design (4th and 5th digits)
The fourth and fifth digits in the model code are responsible for the appearance, location of controls and design features doors. These are the parameters that affect the ergonomics and fit of the refrigerator into the kitchen interior. Knowing these codes helps you understand which side the door opens from and where the handles are located.
The fourth digit often indicates the energy class or design series, but in the context of the design, the fifth digit is more important. It informs about the presence of additional functions, such as a display, a freshness zone, or design features (for example, “for embedding” or with a certain type of handles).
| Position in the code | Value | Example of characteristics |
|---|---|---|
| 4th digit | Series/Design | Classic, Premium, Line |
| 5th digit | Features | Display, Freshness zone, Reversible door |
| 6th digit | Color/Material | White, Silver, Stainless steel |
| 7th digit | Modification | Changes in configuration |
It is important to consider that the manufacturer can make changes to the design without changing the base model. Therefore, when ordering glass shelves or plastic interior elements (drawers, balconies on the door), it is better to focus on the full code, including the last three characters. They indicate a specific modification, which may differ in the color of the plastic or the shape of the handles.
The influence of color on markings
The last digits often encode the color of the case. For example, 000 is white, 010 is silver, 022 is beige. When searching for a spare part where color is important (handle, decorative panel), these numbers are critical.
Refrigerant type and climate version
Environmental standards dictate their own rules, and the plant Atlant is gradually switching to new types of refrigerants. Older models used R134a freon, which is considered relatively safe but has a high global warming potential. In the newest modifications you can find a more environmentally friendly R600a (isobutane).
The type of refrigerant is often not explicitly coded in the visible part of the model number for the consumer, but it is necessarily indicated on the technical sticker (nameplate), usually next to the amount of gas being charged. This is critical information for the repair technician: refilling a system designed for R600a with R134a gas is strictly prohibited due to differences in pressure and oil properties.
Climatic design indicates the range of ambient temperatures at which the refrigerator operates stably. For our latitudes, the following classes are most relevant:
- ❄️ N (Normal) — from +16°C to +32°C. Standard option for heated rooms.
- ❄️ SN (Subnormal) —from +10°C to +32°C. Suitable for rooms where in winter the temperature can drop below +16°C (for example, a cottage or hallway).
- ❄️ T (Tropical) - up to +43°C. A rare class, intended for very hot climates.
Information about the climate class is also contained on the nameplate, but is not always reflected in the short model code. If you plan to install a refrigerator on an unheated loggia, be sure to check for the presence of marking SN or SN-T. Using a class N model at temperatures below +10°C will result in the compressor simply not turning on, since the thermostat will “think” that the chamber is already cold enough.
☑️ Check before purchasing spare parts
Where to find information and how to read the nameplate
The main source of reliable information about your refrigerator is the factory sticker, or nameplate. In refrigerators Atlant it is most often located inside the refrigerator compartment on the right side wall. Less often it can be found on the base part in the front or on the rear wall of the case, but the internal version is standard for most series.
The nameplate contains complete information: full model code, serial number, production date, type of refrigerant and its quantity, energy efficiency class and climate class. When contacting a service center or spare parts store, you need to dictate the model code (for example, XM 4008-000), and not the serial number.
⚠️ Attention: If the sticker inside the camera has worn off or peeled off, do not try to wipe off the residue with aggressive chemicals - you can damage the plastic coating walls. It is better to carefully photograph what is left and refer to the product passport or warranty card, where the code is duplicated.
In some cases, especially on very old models or if documents are lost, you can identify the refrigerator by external features, comparing them with catalogs. However, this method is less accurate. The plant could produce the same visual model in different years with different internal contents (compressors, type of plastic), so relying on a digital code is the only reliable way of identification.
Frequently asked questions (FAQ)
What to do if the code on the sticker is not readable?
If the sticker inside the refrigerator is damaged, try to find a warranty card or instructions - there Often the model is entered manually or stamped. You can also try to find the original box, if it has survived. As a last resort, describe the characteristics (volume, presence of No Frost, location of chambers) to a specialist at the service center - they can identify the model visually.
Does the number 3 in the code mean that the refrigerator is three-chamber?
No, the third digit in the model code (for example, XM 4008) usually indicates the system defrosting. Three-chamber refrigerators (with a freshness zone) may have different designations, but the number “3” in the position of the defrosting system most often indicates a drip system. The number of cameras is usually encoded by the second digit (1, 2 or 3).
Is it possible to find out the year of manufacture by the code?
The year of manufacture is not encrypted directly in the model number (XM 4008-000). The model number indicates the series and characteristics. The year of manufacture is indicated separately on the nameplate in the “Date of Manufacture” column or encoded in the serial number, the format of which is more complex and depends on the year of manufacture (changed over time).
What is the difference between XM 4008 and XM 4009?
The difference in the last digit (8 and 9) indicates a modification. This may be a change in color, replacement of the manufacturer of some components (for example, a compressor or thermostat) with similar ones, change in the design of the handle or internal plastic. Technically, the main parameters (volume, type of defrosting) are most often identical.
Where is the serial number?
The serial number (S/N) is located on the same nameplate as the model. This is usually a long combination of numbers and letters found under or next to the "Model" line. It is unique for each specific device and is used to register the warranty.
