Purchasing new household appliances is always accompanied by the expectation of comfort, but the installation process often confuses users, especially when it comes to fixing internal components. Refrigerators Biryusa are reliable units that require careful handling when first started, and the key point here is the correct removal of fasteners.
Many owners, when encountering large-sized equipment for the first time, do not know that the compressor and other moving parts are securely fixed with special screws for safe transportation. If you ignore this stage, vibration during operation it can lead to serious damage, so the issue of the location of these parts becomes critical immediately after delivery.
In this article we will analyze in detail exactly where the refrigerator Biryusa shipping bolts are located and how to safely dismantle and what nuances must be taken into account in order not to damage the housing or internal mechanisms of the unit.
Design features of compressor fixation
To understand where to look for fasteners, you need to know the design of the refrigeration circuit. In most models Biryusa the compressor, which is the heart of the system, is suspended on shock absorbers that dampen vibration during operation. However, when transported on uneven roads, these shock absorbers are not able to protect the engine from impacts and swaying.
That is why the manufacturer uses rigid clampswhich turn the movable suspension into a monolithic structure. These elements are usually long bolts that pass through the housing or special brackets, resting against the compressor frame. Their task is to completely eliminate any movement of the motor.
It is important to understand that the number of attachment points may vary depending on the series. In older models, there were often four fixation points, while in modern units there may be two or three, but the principle of operation remains unchanged. Spring suspension must be completely unlocked before turning on for the first time.
⚠️ Attention: Operation of the refrigerator with installed transport bolts leads to a sharp increase in noise and vibration levels, and can also cause pipe breaks or destruction of the compressor suspension.
Some users mistakenly believe that if the unit is quiet, then everything is in order, but this is a misconception. Running the engine on a rigid mount creates excess stress in the metal, which shortens its service life of the refrigeration unit. Therefore, a visual inspection of the rear panel is a mandatory procedure.
Location of fasteners on the rear wall
The traditional location for transportation bolts in refrigerators Biryusa is the rear panel of the case. This is where the motor-compressor and condenser unit are located, access to which is limited by a metal casing or an open grille. You will need to approach the back of the refrigerator and carefully inspect the bottom.
The bolts are usually located in the lower third of the back wall, symmetrically on the sides of the compressor or directly above it. They may be body-colored to make them less noticeable, or have a contrasting head (often yellow or red) to attract attention. In some modifications, they are closed with decorative plugs made of plastic or cardboard.
To detect fasteners, good lighting and possibly a flashlight may be required. Look behind the protruding parts of the capacitor grille. If you see the bolt heads passing through the holes in the metal and going deep into the motor, this is exactly what needs to be removed. Transport fixation always located in the area of maximum vibration.
It is worth noting that in models with a bottom freezer, the layout may differ, but the search principle remains the same - We are looking for points of rigid connection between the motor frame and the frame of the cabinet. Sometimes the bolts are not located vertically, but horizontally, screwed in from the side.
Instructions for the safe removal of bolts
The process of removing fasteners does not require complex tools, but demands accuracy. You will need a wrench (usually 10, 12 or 13 mm) or a socket with a wrench. Before starting work, be sure to disconnect the refrigerator from the power supply, if it has already been connected, and provide free access to the rear wall.
First of all, you need to unscrew the nuts that are located on the outside of the case. In some cases, spring washers or bushings may be installed under the nuts; these should be retained, although they are not usually required for reinstallation. After removing the nuts, the bolts are taken out.
☑️ Dismantling algorithm
If the bolts are rusty or stuck, do not use excessive force to avoid tearing them off carving You can use a penetrating lubricant (such as WD-40) by applying it to the threaded joint and waiting 10-15 minutes. After processing, the bolts should come out easier. In rare cases, it is necessary to remove the protective cover of the compressor by unscrewing several screws around the perimeter.
After removing all the elements, it is recommended to rock the refrigerator from side to side (without tilting too much) to make sure that the compressor is now suspended and moves freely inside its bed. This will confirm that transport fasteners has been completely removed.
The specifics of models with top and bottom freezer
The design of refrigerators Biryusa varies depending on the year of manufacture and series, which affects the location of fasteners. In classic two-chamber models with a top freezer (series 133, 134), the bolts are most often located symmetrically on the sides of the compressor on the rear wall.
In models with a bottom freezer (series 138, 139, 148, 149) the layout could be more dense. Here the bolts are sometimes hidden deeper behind the radiator grille. Also, some modern modifications use a fastening system where the bolts fix not the compressor itself, but the support frame on which it stands.
Features of old Biryusa models
In Soviet and early Russian Biryusa models, shipping bolts could be installed not only at the back, but also inside the freezer, fixing shelves or drawers. Carefully inspect the internal space if there are no fasteners at the back.
The table below will help you navigate depending on the series of the unit, although it is always better to check the exact location visually:
| Refrigerator series | Type of location | Quantity bolts | Location |
|---|---|---|---|
| Turk 133/134 | Classic | 2-4 pcs. | Rear wall, on the sides of the motor |
| Biryusa 138/139 | Bottom freezer | 2-3 pcs. | Behind bars, below |
| Biryusa 148/149 | No Frost | 2 pcs. | Side brackets |
| Turk 6/11 | Small-sized | 2 pcs. | Rear, at reasons |
You should not rely only on the table, since factory changes in the design can be made without warning. Visual inspection remains the most reliable diagnostic method.
What to do if the bolts are not found or lost
The situation when the user cannot find the transport bolts occurs quite often. This may mean that they have already been removed upon delivery by the store or by the previous owners if the equipment is used. In this case, you should check the package: sometimes the bolts are in a bag with documents or attached with tape to the inner wall of the refrigerator compartment.
If you are sure that the bolts have not been removed, but they are not in place, your model may have used a different fixation system, for example, wooden blocks or foam inserts that are removed from the inside or from below. There are models where the compressor is fixed only with cardboard gaskets that do not require unscrewing.
If the bolts are lost during repeated transportation (for example, when moving), it is not necessary to look for original ones. You can use any bolts, nuts and washers of suitable diameter and length. The main thing is to ensure rigid fixation so that during transportation the compressor does not hit the walls of the housing.
The absence of transport bolts during storage or moving is a risk, but for normal stationary operation they are not needed. Moreover, their presence in a working refrigerator is an emergency.
Consequences of operation with installed fasteners
Ignoring the need to remove transportation bolts leads to catastrophic consequences for refrigeration equipment. The first and most noticeable sign becomes excessive noise. The refrigerator begins to hum, knock and vibrate so that it can move along the floor.
Vibration is transmitted to the entire body, which can lead to the destruction of internal shelves, glass and plastic elements. But the main danger is hidden inside: constant shock loads on the compressor shaft lead to rapid wear of the bearings and jamming of the motor. Repairing or replacing the compressor in such cases is often not economically feasible.
⚠️ Attention: If you turn on the refrigerator and hear a loud metallic knock or hum, immediately unplug it and check for the presence of shipping bolts. Continuing to operate in this mode will kill the compressor in a matter of hours.
Deformation of the refrigeration circuit tubes is also possible. A rigid suspension does not compensate for thermal expansion and vibration, which can lead to microcracks in soldering and leakage refrigerant. Restoring the tightness of the system requires calling a technician and evacuation, which is an expensive procedure.
Frequently asked questions (FAQ)
Is it possible to turn on the Biryusa refrigerator immediately after delivery?
No, you cannot turn it on right away. After delivery, especially if the refrigerator was lying during transportation, you need to wait 2 to 4 hours (or better 8-12 hours if there was a negative temperature) for the oil to drain into the compressor. Also during this time you need to have time to remove the shipping bolts.
Do you need to keep the shipping bolts after installation?
Yes, they definitely need to be kept in a bag with documents. If you ever decide to move or sell your refrigerator, it will again need to be securely secured for safe transportation. Without bolts, the compressor can come off when shaking.
How many bolts should a Biryusa refrigerator have?
The number varies from 2 to 4 pieces depending on the model and year of manufacture. Most often there are 2 or 4 bolts. The exact number is indicated in the operating instructions for your specific model.
What to do if the bolt is rusty and cannot be unscrewed?
Do not use brute force. Treat the connection with penetrating lubricant (WD-40 or equivalent), wait 15-20 minutes. If it doesn’t help, you can gently heat the nut with a hair dryer (not an open fire!) so that the metal expands and try again.
Where is the instruction manual for my Biryusa model?
Paper instructions should be included. If it is lost, the electronic version for any model can be found on the manufacturer's official website in the "Support" or "Documentation" section by entering the model (for example, Biryusa 134).
