Purchasing a new refrigerator is always a joyful event, marking the renewal of household appliances in the kitchen. However, the process of installing a brand unit Biryusa requires special attention to details that are hidden from view during the first inspection. We are talking about special fasteners that secure the moving parts of the compressor during transportation. These details are critical for the safety of the device on the road, but are absolutely contraindicated for its normal operation.
Many users mistakenly believe that it is enough to simply plug in the device after unpacking. This dangerous misconception can cost you expensive repairs or a complete replacement of the compressor. Transport bolts The spring suspension of the motor is rigidly fixed, preventing it from dampening vibrations. If they are not removed, the refrigerator will operate at extreme noise levels and will quickly fail. In this article, we will analyze in detail where exactly these elements are located in various models and how to dismantle them correctly.
Design features of the rear panel
In order to find the fixation points, you need to approach the refrigerator from the back. It is there, on the lower part of the housing, that the compressor unit is located. Depending on the specific series of refrigerators Biryusa, the design may differ, but the general principle remains the same. The fastener is always in close proximity to the motor, holding its frame relative to the metal housing.
Usually you will see two to four bolts passing through the eyes on the compressor frame and screwed into the housing or special brackets. Their heads are often hexagonal in shape, which makes installation easier at the factory, but may require the user to have the appropriate tools. Thread diameter These elements are usually 10 or 12 millimeters, which makes them massive enough to support the weight of the motor when shaking.
In some modern models with system No Frost or improved sound insulation, access to the bolts can be partially covered with a decorative plastic cover or mesh. In this case, you will need to carefully remove this element to gain full access to the fastener. Do not use excessive force, the plastic can be brittle, especially if the refrigerator has just been brought in from the cold.
⚠️ Attention: Before starting any dismantling work, make sure that the refrigerator is unplugged from the electrical outlet. Although the bolts are located far from electrical contacts, compliance with safety precautions when working with household appliances is a mandatory rule.
It is important to note that the location of the bolts is symmetrical relative to the center of the compressor. This ensures even load distribution during transportation. If you see one bolt on the left, then with a high degree of probability a similar element will be present on the right side of the motor frame.
Step-by-step instructions for dismantling
The process of removing shipping fasteners does not require complex technical skills, but requires accuracy and the right tool. To work, you will need a wrench (usually 10 or 12 mm) or a socket with a wrench. In some cases, if access is limited, a flathead screwdriver may be useful to pry off washers or protective sleeves.
Start by loosening the bolts by turning them counterclockwise. Do not unscrew them completely at once. First make a few turns on each bolt to evenly release the tension from the compressor frame. Abruptly removing the fixation on one side can lead to distortion and damage to the suspension springs.
☑️ Algorithm for removing bolts
After the bolts are unscrewed, carefully inspect the holes. Often rubber or plastic bushings are removed along with the metal rod. They also need to be removed as they are part of the transport system. If you leave the bushings in the holes, they can interfere with the normal vibration of the case during operation.
The final step is the installation of plastic plugs. The refrigerator Biryusa always comes with special decorative lids that cover the resulting holes. This not only improves the aesthetic appearance of the rear panel, but also prevents dust and moisture from entering the housing in the area of the engine compartment.
Model differences and series specifics
The plant Biryusa produces a wide range of refrigeration equipment, and the design of fasteners may vary. In classic models with a top freezer, the bolts are most often located horizontally, passing through the side eyes of the frame. In models with a bottom freezer or Side-by-Side type, the fastening pattern can be vertical.
Below is a table systematizing information on the location of fasteners depending on the type of structure:
| Model type | Quantity bolts | Location | Tool |
|---|---|---|---|
| Classic (2 chambers) | 4 pcs. | Rear, horizontal | Key 10 mm |
| Small-capacity (single-chamber) | 2-3 pcs. | Rear, at the base | Key 12 mm |
| Built-in series | 4 pcs. | Bottom frame | Head 10 mm |
| Red Line Series | 3 pcs. | Asymmetrical | Key 12 mm |
It is worth considering that in new modifications the manufacturer can change the suspension design. For example, in some budget series, transport brackets may be used instead of bolts, which must be completely unscrewed. Always carefully study operating instructionsthat comes with your specific device.
Nuances of old models
In Biryusa refrigerators produced before 2010, there was often a design where the transport bolts had additional fixing nut. It must be loosened first before unscrewing the main rod. Modern models do not have such a nut.>
If you are the owner of a rare or old model, and the standard circuit is not suitable, try to visually track the vibration path from the compressor to the housing. Transport fasteners will always be on the line where this vibration breaks, rigidly connecting the moving and stationary parts.
Consequences of ignoring dismantling
The question “what will happen if you don’t unscrew the bolts?” This is the question asked by anyone who doubts the need for this procedure. The answer is clear: operating the refrigerator with the transport locks installed will lead to serious mechanical damage. A compressor, deprived of the ability to absorb shock, will transfer all the vibration to the housing and pipelines.
The first sign of a problem will be an unnaturally loud hum and rattling, which intensifies when the engine starts. However, noise is just the tip of the iceberg. Constant vibration without shock absorption leads to fatigue failure of the metal tubes of the evaporator and condenser. The risk of tube rupture and refrigerant leakage when the compressor is running with bolts increases by 90% in the first month of operation.
⚠️ Attention: Operating the compressor with a fixed suspension causes overheating windings and rapid wear of bearings. This can lead to the motor burning out long before the warranty period expires.
In addition, vibration is transmitted to the floor and furniture, which can cause destruction of the floor covering or loosening of the kitchen unit. Therefore, removal transport bolts is not just a formality, but a necessary condition for the long life of the equipment.
Where to store the dismantled fasteners
After successful dismantling, owners often have a question: where to put these massive bolts? Throwing them away is strictly not recommended. In the event of a breakdown or move, you will need to fix the compressor again, and the lack of standard fasteners will create big problems.
The optimal place for storage is inside the refrigerator or freezer, in a bag with documents. However, remember that there may be condensation when you first turn it on, so it is better to use a sealed bag. Some users attach the bolts with tape to the back wall of the refrigerator itself, but this is not always aesthetically pleasing or reliable.
If you plan to sell the refrigerator in the future, having a full set of shipping elements will significantly increase the liquidity of the device. Buyers are often afraid to take equipment without original fasteners, fearing hidden damage to the compressor during previous transportation.
Frequent errors during installation and startup
Even after removing the bolts, users often make mistakes that nullify all efforts. One of the most common is connecting the device to the network too early. If the refrigerator was transported lying down or simply shaken strongly, the oil in the compressor needs time to drain into the crankcase.
The second mistake is ignoring the alignment of the legs. After removing the transport locks, the housing becomes movable on springs. It is necessary to correctly align the support legs so that the refrigerator is stable and has a slight tilt back for proper closing of the doors.
Also, do not overload the refrigerator with food during the first day of operation. Let the compressor come into operation and cool the chambers without unnecessary heat load. This will extend the resource Turks and ensure a stable temperature.
Questions and answers (FAQ)
Is it possible to unscrew only two bolts out of four?
No, this unacceptable. All transport elements must be removed. The bolts left will continue to rigidly fix part of the frame, which will lead to distortion of the compressor during operation and its rapid failure.
What to do if the plugs for the holes are lost?
You can operate the refrigerator without them, but it is better to close the holes so that dust does not get inside. You can use a piece of electrical tape, a plastic plug of a suitable size, or order a set of plugs from a service center.
Do you need to lubricate the threads of bolts before storing them?
It is not necessary to lubricate the threads, since the bolts are stored in a dry place. However, if you live in a region with high humidity, a light layer of machine oil will prevent corrosion of the metal over years of storage.
Does the Biryusa refrigerator hum immediately after turning it on without bolts?
A slight hum in the first minutes of operation is normal, the refrigerant is being pumped. However, there should not be any strong rattling or vibration radiating to the floor. If the noise persists, check whether the tubes are touching the housing or each other.
