Refrigerator Biryusa 129 is a popular model among Russian consumers due to its spaciousness and reliability. However, in order for the device to work as efficiently and for a long time as possible, a number of preparatory actions must be carried out immediately after purchase. Incorrect initial operation can lead to a reduction in the service life of the compressor or a violation of the temperature regime.
In this guide we will analyze in detail all the setup steps: from unpacking to setting the optimal thermostat parameters. You will learn how to correctly activate the fast freezing mode and what to do if the unit begins to make strange sounds.
Primary preparation and installation of the unit
The first step after delivering the equipment to the apartment is its unpacking and visual inspection. Make sure there are no dents on the cabinet and that the doors open freely. The shipping bolts, if they are present on the back wall, should be unscrewed, but in the model Biryusa 129 most often only the internal shelves are fixed.
It is critically important to allow the refrigerator to settle after transportation, especially if it was transported lying down. The oil in the compressor must drain back into the crankcase, otherwise water hammer may occur during startup.
⚠️ Attention: If the refrigerator was transported lying down, let it stand upright for at least 4-6 hours before plugging it in. In winter, it is better to increase this interval to 12 hours.
The choice of installation location also plays a key role. The unit should not be placed close to a wall or furniture, as it requires air circulation to cool the condenser. The minimum gap at the back should be at least 5-7 centimeters.
After installation, wipe the internal chambers with a damp cloth using a weak soda solution. This will remove the smell of new plastic and residual factory grease.
Temperature control
The main control element in Biryusa 129 is a mechanical thermostat located inside the refrigerator compartment. Typically this is a rotary knob with a number designation from 1 to 7 (or Min/Max). Understanding the principle of its operation is the key to the correct operation of the equipment.
The numbers on the regulator do not indicate degrees Celsius, they indicate the intensity of the compressor. The higher the number, the lower the temperature inside the chamber. Setting the value to the maximum (7 or Max) forces the motor to work without interruption, which can lead to freezing of products.
For standard food storage mode, the optimal position of the handle is between the divisions 3 and 4. This ensures that the temperature is maintained in the range of +2...+5°C, which is ideal for most products.
- 🌡️ Position 1 (Min): minimal cooling, used in the cold season or with low load.
- ❄️ Position 3-4: standard operating mode for daily use.
- 🧊 Position 6-7 (Max): intensive cooling mode, it is not recommended to keep it constantly.
If you notice that the food in the refrigerator compartment is freezing, you need to turn the knob towards lower values. And vice versa, if the milk quickly sours, add power.
It is worth remembering that changing the position of the thermostat does not give an instant result. The compressor needs from 1 to 2 hours to stabilize the temperature background after switching.
Using the quick freezing function
The model Biryusa 129 often has a “Super Freeze” or “Quick Freeze” function. This mode is necessary when you need to freeze a large amount of fresh food without defrosting existing stocks.
Activation is performed by a button or switch, often located next to the thermostat or on the control panel (depending on the year of manufacture of the modification). When turned on, the corresponding indicator lights up and the compressor starts working continuously.
⚠️ Attention: Do not leave the fast freezing mode on for more than 24 hours. This can lead to an overload of the electrical network and excessive freezing of the evaporator.
After the food has frozen (usually after a day), the function must be forcibly turned off, returning the refrigerator to normal operation. In some modifications, shutdown occurs automatically after a certain time.
Why can’t you freeze hot food?
Loading hot products causes a sharp jump in temperature, which causes the compressor to wear out, and also leads to the formation of ice and damage to neighboring products.
The use of this mode is justified when preparing berries, meat or mushrooms in season. The rest of the time, keep the function turned off to save energy.
Distribution of products across the storage area
Proper setting of the refrigerator is not only about the knobs, but also about proper placement of the contents. In Biryusa 129 temperature zones are distributed unevenly, and this must be taken into account.
The coldest place is located at the back wall, especially in the upper part, next to the freezer. You shouldn't store vegetables that might freeze there. The door is the warmest zone, subject to temperature changes when opening.
| Zone | Temperature | What to store |
|---|---|---|
| Top shelf | +3...+5°C | Ready food, drinks, confectionery products |
| Bottom shelf | +2...+4°C | Raw meat, fish, dairy products |
| Box (vegetable) | +5...+8°C | Vegetables, fruits, herbs |
| Door | +7...+10°C | Sauces, medicines, bottled drinks |
Do not fill the refrigerator with food to capacity. Cold air should circulate freely between the shelves and walls. If all the cracks are clogged, the temperature in some areas may rise above the safe one.
Cover food with a lid or film. This will prevent drying and mixing of odors, and will also facilitate the operation of the moisture removal system.
Elimination of noise and vibration during operation
Many users are faced with the fact that after setup Biryusa 129 it begins to buzz or vibrate loudly. Often the reason lies not in a breakdown, but in incorrect installation.
Check whether the refrigerator body is touching walls, furniture or curtains. Even a light touch can transmit vibration, increasing the hum. Also make sure that bottles and cans are not touching each other inside the chamber.
- 🔧 Check the adjustment of the legs: all four supports should be firmly on the floor.
- 🔍 Inspect the compressor from the back: the tubes should not touch each other or the housing.
- 🧹 Make sure that rear ventilation is clear: dust on the condenser causes overheating and noise.
If the hum is accompanied by clicking sounds, this may be a sign of a thermal relay or expansion of materials. However, a constant knocking requires calling a specialist.
☑️ Noise diagnostics
It is important to distinguish operating hum of the compressor and extraneous sounds. The gurgling of the refrigerant is a normal physical process that does not require intervention.
Maintenance and defrosting of the system
The refrigerator Biryusa 129 refers to the defrosting system Manual Defrost (manual defrosting) or semi-automatic (“crying” back wall in the refrigerator compartment). This means that the freezer will have to be defrosted manually periodically.
Ice more than 5 millimeters thick significantly impairs heat transfer and causes the compressor to consume more electricity. It is recommended to defrost at least once every 6 months.
⚠️ Attention: Never use a knife, screwdriver or other sharp objects to chip ice. You can damage the evaporator, and the refrigerator will stop freezing.
For quick defrosting, you can put a bowl of hot water in the chamber and close the door. The steam will speed up the melting of the ice. After the procedure, be sure to wipe the chamber dry.
Do not forget to clean the drainage hole in the refrigerator compartment. It is located at the bottom of the back wall. Clogging leads to water starting to flow onto the floor and not into a special tray.
Frequently asked questions (FAQ)
Why does the Biryusa 129 refrigerator get very hot on the sides?
In modern models, the condenser (heat exchanger) is often built into the side walls of the case. Heating up to 40-50 degrees in the first days of operation or during active freezing is a normal phenomenon, indicating heat removal.
How long should the compressor operate normally?
The operating and rest time depends on the load and temperature in the room. Typically the cycle is 10-15 minutes of work and 15-20 minutes of rest. If the motor hums constantly, check the tightness of the door seal.
Is it possible to transport Biryusa 129 lying down?
Transporting lying down is undesirable, but is permissible if precautions are taken. You only need to place it on one of the sides (usually indicated in the instructions) so that the oil does not leak into the circuit. After installation, a period of at least 6 hours is required.
What to do if water appears in the chamber?
Check whether the drainage hole is clogged. It could also be due to a door not being closed tightly or hot products being installed. If water appears constantly, the drain groove may have shifted.
