Operation Biryusa 120 requires periodic attention, since this model belongs to the class of equipment with a manual defrosting system. Ignoring the formation of a snow coat on the evaporator leads to increased energy consumption and reduced compressor efficiency. The owner must independently control the thickness of the ice and carry out the thawing procedure when a critical value of 5-7 millimeters is reached.
The process of a full cycle of disconnecting the unit from the power supply is necessary to restore heat exchange and extend the service life of refrigeration equipment. Unlike modern systems No Frost, here moisture from the products settles on the back wall of the chamber, turning into a dense layer of frost. Regular maintenance guarantees the preservation of freshness of products and stable temperature conditions inside the chambers.
Frequency of defrosting and signs of the need for the procedure
You can visually determine the moment when intervention is required. The snow coat grows unevenly, but its appearance on the back wall of the freezer compartment is the first signal. If you ignore this sign, the ice will begin to occupy the useful volume and worsen the contact of the evaporator with the air. Biryusa refrigerator requires intervention, it can be done visually. The snow coat grows unevenly, but its appearance on the back wall of the freezer compartment is the first signal. If you ignore this sign, the ice will begin to occupy the useful volume and worsen the contact of the evaporator with air.
The frequency of the procedure depends on environmental conditions and the mode of use of the equipment. In the hot season or when doors are opened frequently, ice formation occurs more intensely. The standard maintenance interval is once every 3-6 months, but the specific timing is dictated by the actual condition of the unit.
⚠️ Attention: If the ice crust has reached a thickness of more than 1 centimeter, the compressor begins to work almost non-stop, trying to compensate for the loss of cooling capacity.
There are a number of indirect signs indicating that that defrosting is already overdue. Owners often notice that food in the freezer has become less freezing (freezing), and the engine operating time has increased. A characteristic hum or vibration may also appear due to system overload.
Preparatory stage before turning off the power
Before starting active actions, it is necessary to properly prepare model 120 for the procedure. This will minimize the risk of food spoilage and protect the kitchen floor from flooding. First, you should empty the chambers of the contents by putting the food in thermal bags or bowls with ice if defrosting takes place in the summer.
It is important to prepare a place in advance for collecting melt water. The design Turk is not always equipped with an external drainage hole, so water will flow to the bottom of the chamber. Place a flat tray under the unit or cover the floor with absorbent rags and towels.
- 🧊 Remove all shelves and drawers for separate washing with warm water.
- 🔌 Disconnect the appliance from the electrical network by removing the plug from sockets.
- 🚪 Leave the doors of the freezer and refrigerator compartments completely open.
- 🧹 Prepare soft rags and a basin to collect the draining water.
Don't forget to check the stability of the refrigerator. During defrosting, it should not wobble, and the doors should be locked in the open position so as not to slam from a draft. This will provide safe access to internal surfaces.
Natural defrosting: safe and recommended method
The most gentle way to (remove) ice for an evaporator is natural defrosting. The process takes from 8 to 24 hours depending on the thickness of the ice layer and the room temperature. At this time, you should not interfere with the operation of the unit or try to speed up the process mechanically.
The water will gradually flow down, so periodically check the fullness of the placed containers or the condition of the rags. If you use natural method, the risk of damaging thin radiator tubes is reduced to zero. This is especially important for older models, where the metal can be thinned by corrosion.
While waiting, you can start cleaning the vacated shelves and drawers. Use mild detergents without abrasive particles. After washing, rinse the plastic thoroughly and let it dry so that there are no foreign odors left in the chamber.
Accelerated methods and prohibited techniques
Sometimes time plays against the owner, and there is a need to speed up the process. There are safe ways to do this, but there are also methods that are strictly prohibited by manufacturers Biryusa. Understanding the difference between them will save the equipment from expensive repairs.
A safe accelerator is to use a fan directed into an open chamber, or containers with hot water (not boiling water) mounted on wooden planks. The heat will circulate and the ice will begin to melt faster. The main thing is not to pour water directly on the ice.
⚠️ Attention: It is strictly forbidden to use sharp objects (knives, screwdrivers, chisels) to chip ice. One awkward movement can puncture the evaporator, which will lead to a freon leak and complex repairs.
It is also not recommended to use a hair dryer at maximum temperatures or heaters in close proximity to plastic. A sharp change in temperature can cause deformation of internal panels or cracking of plastic structural elements.
Why should you not pour boiling water?
Pouring boiling water onto an ice block is dangerous due to the risk of thermal shock (thermal shock) for plastic and rubber seals, as well as due to the fact that water can instantly turn into steam and damage electrical contacts.
Moisture removal and sanitary treatment
After all the ice has melted, it is necessary to carefully remove any remaining moisture. Even a small puddle at the bottom can become a source of unpleasant odors or mold in the future. Use a dry soft cloth to wipe all accessible surfaces.
Pay special attention to the drainage hole, if it is designed in the refrigerator compartment. It can be carefully cleaned with a special soft brush or cotton swab to ensure free flow of condensate in the future.
| Processing stage | Tools | Recommended product | Purpose |
|---|---|---|---|
| Washing shelves | Sponge, basin | Soda solution or mild detergent | Removing dirt |
| Wipe the walls | Microfiber | Warm water | Condensation removal |
| Disinfection | Spray, fabric | Specialized spray for refrigerators | Elimination of bacteria |
| Drying | Dry towel | No | Preparation for switching on |
If there was an unpleasant substance inside the chambers odor, you can use activated carbon or special odor absorbers. Place them in the corners of the chambers before closing the doors during the drying stage.
Starting the refrigerator after defrosting
The final stage is the correct start of the unit. Make sure all interior surfaces are completely dry. Turning on a wet appliance can lead to a short circuit or the formation of a new ice crust instantly.
Plug in the refrigerator, but do not load food immediately. Let it run idle for 1-2 hours so that it reaches the required temperature and the compressor turns off automatically. Only after this can you add food.
☑️ Ready to start
During the first hours of operation, the unit may make a little more noise than usual - this is normal for a system that has just gone through a cycle of defrosting and filling with refrigerant. After a few hours, the operating mode will stabilize.
Frequent errors and precautions
Many users make typical mistakes when trying to save time. For example, leaving the light on in the chamber during defrosting. The light bulb produces heat, but also creates a risk of short circuiting if water gets in.
Another mistake is using aggressive chemicals to remove ice. Salt or chemicals can damage the metal coating of the evaporator, accelerating corrosion. For Biryusa 120 only clean water and neutral products are suitable.
⚠️ Attention: Technical characteristics and design of the drainage system may vary slightly in different modifications of the model. Always check the data sheet for your specific device before using chemicals.
Regular care and maintenance intervals will allow your refrigerator to serve for many years without loss of efficiency. Taking good care of your equipment pays off with stable operation and low energy bills.
What to do if it doesn’t cool after defrosting?
If, after turning on and going through a full cycle, the compressor works, but there is no cold, the evaporator may have been damaged during cleaning or a power surge has occurred. A call from a specialist is required.
How long does it take to completely defrost Biryusa 120?
The time depends on the thickness of the ice and the temperature in the room. The process usually takes 10 to 24 hours with natural thawing. Using fans can reduce this time to 4-6 hours.
Is it possible to defrost a refrigerator without unplugging it?
No, this is strictly prohibited by safety rules and instructions. The compressor must be de-energized to avoid electric shock and motor damage if water gets in.
Do you need to wash the inside of the refrigerator after each defrost?
Yes, this is a hygienic necessity. As the temperature rises, bacteria begin to actively multiply. Wiping with a weak solution of soda or vinegar disinfects surfaces.
What to do if water does not drain into the drain?
The drainage hole is probably clogged. It needs to be carefully cleaned with a soft wire or a brush, after defrosting the ice cap with warm water.
