Setting freezer compartment in the Biryusa refrigerator

Brand refrigerators Biryusa are deservedly popular due to their reliability and adaptability to domestic operating conditions, however, the correct initial setup of the freezer compartment often raises questions among new owners. Proper temperature control is a critically important task, since it directly affects the shelf life of meat and fish products, as well as the energy consumption of your device. Many users mistakenly believe that it is enough to simply plug in the appliance, but to achieve optimal compressor performance and maintain food quality, a number of sequential actions must be performed.

During operation, you may encounter the need to change the standard factory settings, for example, when the summer heat sets in or, conversely, severe winter frosts, if the refrigerator is in an unheated room. Understanding the principles of operation of the thermostat and the system quick freezing will allow you not only to save on electricity bills, but also to significantly extend the life of the compressor itself. In this article, we will analyze in detail all the stages of setup, the nuances of the operation of mechanical and electronic control panels, and also point out typical mistakes that inexperienced users make.

Before you start actively loading products, you need to let the equipment get into operating mode, which is especially important for models with a drip thawing system. Incorrect load distribution in the first hours of operation can lead to incorrect readings by the temperature sensor, causing the unit to operate under overload. Let's look at how to properly prepare and configure your refrigerator for long-term and efficient service.

Primary preparation and placement of equipment

The first step before any setup is the correct installation of the refrigerator Biryusa on the prepared place. The device must stand strictly horizontally, which is checked by the building level, since skewed housing can disrupt the circulation of refrigerant and the operation of the doors. If the door does not close tightly due to the slope of the floor, warm, humid air will constantly enter the freezer, which will lead to the formation of a thick ice crust and malfunction of the thermostat.

After transportation, especially if it was carried out at sub-zero temperatures, the refrigerator should not be turned on immediately. The oil in the compressor must drain into the crankcase and warm up to room temperature, otherwise a hydraulic shock is possible, which can damage the engine. Typically, manufacturers recommend keeping the equipment in an upright position for 2 to 4 hours before starting it for the first time, but in winter it is better to increase this time.

⚠️ Attention: Do not install the refrigerator close to a wall or furniture. For normal operation of the condenser (grids at the back or on the sides), a gap of at least 5-7 cm is required for free air circulation.

It is also important to take into account the temperature conditions in the room where the unit will be located. Most models Biryusa are designed for operation in the SN-T climate class, which means operation at ambient temperatures from +10 to +38 degrees Celsius. Installation in an unheated garage or on a balcony in winter will require the use of a special winter kit or heating the thermostat zone, otherwise the compressor may simply not start.

Adjusting a mechanical thermostat

In classic models of refrigerators Biryusa the temperature is controlled using a mechanical thermostat, which is usually a rotary knob inside the refrigerator compartment or on the front panel. The regulator scale is most often graduated with numbers from 1 to 5, 6 or 7, where the numbers indicate not degrees Celsius, but the cooling intensity. The higher the number you set on the regulator, the colder it will be in the freezer and refrigerator compartments.

For during normal storage of food under normal conditions, it is recommended to set the regulator knob to the middle position, usually the numbers 2 or 3. If you set the maximum value (for example, 5 or 7), the compressor will work almost without interruption, trying to achieve extremely low temperatures, which will lead to increased energy consumption and accelerated wear of components.

• 🌡️ Position 1-2: Minimum cooling, suitable for storing a small amount of food or during the cold season.
• ❄️ Position 3-4: Optimal mode for daily use and standard freezer load.
• 🧊 Position 5-7: Maximum cold mode, used only for quick freezing or at very high temperatures in the room.

It is worth remembering that changing the position of the thermostat knob does not give an instant result. The compressor needs time to change its operating cycle, and the air in the chambers needs time to cool or warm up to a new set temperature. Therefore, you should not turn the regulator every half hour, expecting an instant effect; you should evaluate the result of the setting no earlier than after 5-6 hours of operation.

Using the fast freezing mode

Function Super Freeze or “Quick freezing” is one of the key tools for refrigerator owners Biryusa, allowing Freeze large quantities of fresh food for a short time without losing their structure. When this mode is activated, the thermostat ignores the current temperature in the chamber and forces the compressor to work continuously until you manually turn off the function or the emergency timer goes off (usually after 24-48 hours).

This mode must be used in advance, before adding products. It is recommended to turn on the fast freeze button several hours (optimally 3-4 hours) before you place meat, fish or berries in the freezer. This will create a supply of cold, and the products will freeze evenly, which will prevent large ice crystals from rupturing cellular tissues.

Sequence of actions:
1. Press the "Super Freeze" button on the control panel.
2. The corresponding indicator (usually yellow or red) will light up.
3. Load the food into the freezer.
4. After 24 hours, turn off the mode to return to normal operation.

It is important not to forget to turn off the fast freezing mode in a timely manner. If you leave it on constantly, the temperature in the freezer may drop below -24...-26 degrees, which will lead to excessive freezing of the evaporator and the compressor working at its limit. In some older models, this mode does not have auto-shutoff, so user control is required.

Setting up electronic controls and display

Modern models Biryusa are equipped with electronic control units with digital displays, where the temperature is set in degrees Celsius, which greatly simplifies control of the microclimate inside the chambers. In such systems, the freezer compartment is configured independently of the refrigerator compartment, which allows flexible control of storage modes. To change parameters, the “Mode” or “Freezer” button is usually used, and the values ​​are adjusted with the “+” and “-” buttons.

The optimal temperature for the freezer is considered to be the range from -18 to -20 degrees Celsius. With such indicators, most bacteria and microorganisms are inactive, and products can be stored for months without loss of taste. Reducing the temperature below -24 degrees has no practical meaning for domestic use and only increases energy consumption.

If A flashing indicator or sound signal lights up on the display, this often indicates an increase in the temperature in the chamber above the permissible threshold (usually above -10...-12 degrees). In this case, it is necessary to check the tightness of the door closure, the presence of products covering the sensor, or the amount of warm food loaded. Electronics Biryusa are sensitive to power surges, so it is recommended to use a surge protector to protect the control board.

Why is the alarm indicator blinking?

If the indicator is blinking and the temperature is normal, you may have recently opened the door or loaded a lot of warm water products. The system simply records a temporary increase in temperature. If the blinking continues for a long time when the door is closed, check the seal or call a technician.

Seasonal features of operation

Operating the refrigerator Biryusa in different climatic conditions requires correction of the thermostat settings. In the summer, when the temperature in the apartment rises, the heat transfer of the condenser deteriorates, and the compressor takes more time to cool the chambers. During this period, it is advisable to shift the regulator towards lower temperatures (large numbers on the scale) to compensate for the heating.

In winter, the situation can be diametrically opposite, especially if the refrigerator is in the kitchen with frequently opened windows or in the hallway. At low indoor temperatures, the compressor may turn on too rarely, which will lead to defrosting of food in the freezer. In such cases, the regulator should be moved to the minimum cooling position (number 1 or 2) to give the motor the opportunity to work more often, but in short cycles.

• ☀️ In summer: Increase the cooling power, make sure that direct sunlight does not fall on the case.
• ❄️ In winter: Make sure that the temperature in the room does not drop below +10 degrees, otherwise the oil in the compressor will thicken.
• 🌧️ In the off-season: Return the regulator to the middle position (3 or 4) for standard operation.

It is also worth considering air humidity. In damp rooms (for example, in a private house or country house), condensation may appear on the outer walls of the freezer, and ice may form more actively inside. In such conditions, it is not recommended to set the maximum cooling power so that the temperature difference between inside and outside is not critical.

Repair and maintenance

During the process of setup and operation, users may encounter a situation where the freezer Biryusa grows with a thick layer of snow and ice, even with proper operation. Most often, this is not due to a breakdown, but to a violation of the tightness of the circuit or improper installation of products. If you see a “fur coat” more than 5-7 mm thick, it is necessary to defrost it, since ice is a heat insulator and interferes with effective cooling.

Another common problem is insufficient cooling when the thermostat is set correctly. The reason may be that the ventilation holes between the chambers are clogged (in models with one compressor) or the freezer is tightly loaded to the top, which blocks the circulation of cold air. Products should lie freely without blocking the air flow.

⚠️ Attention: Never use sharp objects (knife, screwdriver) to chip ice in the freezer. Damage to the evaporator will lead to failure
