The purchase of new household appliances is always accompanied by the joy of updating the interior and hopes for many years of service, but the euphoria of the purchase can quickly disappear if you ignore the preparatory stage before the first use.
Refrigerators of the brand Biryusa, like most models from other manufacturers, are equipped with a special system for fixing the moving parts of the unit, which protects them from damage during loading, unloading and delivery to their destination.
Ignoring the need to dismantle these fasteners leads to critical breakdowns of expensive equipment in the first minutes of operation, so it is extremely important to carefully study the design of the back panel of your device before plugging it into a socket.
Design features of the fixation system
The transportation protection system is a set metal bolts and rubber bushings that rigidly connect the frame of the refrigerator with movable compressor (motor-compressor).
Some models may use additional brackets or strips, however, the classic scheme for most units Biryusa implies the use of four bolts located in the lower part of the rear wall.
These elements are necessary so that the heavy engine does not dangle inside the housing when shaking, which could lead to broken tubes or damage to the suspension, but during operation they become unnecessary and even dangerous.
⚠️ Attention: If you If you find that the bolts have already been unscrewed before you in the store or upon delivery, be sure to check whether the special plastic plugs included in the kit are installed in their place to prevent dust from getting inside the case.
Understanding exactly how it works compressor suspensionhelps you understand the importance of the wedging procedure: without rigid fixation during operation, the engine will vibrate, creating extreme noise and destroying itself.
Necessary tools and site preparation
To carry out the dismantling procedure, you do not need complex professional tools or specific mechanic skills, a basic set that is available to any home craftsman is sufficient.
You you will need open-end wrench (most often size 13 or 14, depending on the year of manufacture of the model) or a head with a knob, as well as a container for storing the removed parts.
Prepare in advance the place where you will put the removed bolts, nuts and bushings, since the loss of even one small washers may cause the locking system to not snap into place during return transportation.
- 🔧 An appropriately sized open-end wrench or set of ratchet sockets to speed up the process.
- 🧤 Work gloves to protect your hands from possible sharp metal edges on the back wall.
- 📦 A box or thick bag to safely store all dismantled items.
- 🔦 A flashlight to better illuminate the bottom of the unit where the bolts are usually located.
Get some space around the refrigerator to allow easy access to the back wall from all sides, as you may have to tilt the unit or walk around it around.
Step-by-step algorithm for dismantling fasteners
The process of removing transport bolts from the refrigerator Biryusa is technically simple, but requires accuracy and adherence to a certain sequence of actions to achieve the result.
First, make sure that the refrigerator is level on the floor and nothing prevents you from approaching its back, then visually determine the location of the fixing elements.
Using the prepared tool, start loosening the nuts, but do not unscrew them completely at once, first just remove all four bolts to make sure that they give in.
☑️ Check before starting
After the nuts are loosened, unscrew the bolts completely and carefully remove them along with the rubber bushings, being careful not to drop them on the floor so as not to lose small parts.
Carefully inspect the holes: in some modifications, the rubber bushings may remain inside the case, and they need to be carefully pryed up and pulled out.
Table compatibility of key sizes
The sizes of fasteners may vary depending on the series and year of production of your model, so it is important to know which tool to prepare in advance.
| Refrigerator series | Fastening type | Key size | Number of bolts |
|---|---|---|---|
| Biryusa 6, 8, 10 | Threaded connection | 13 mm | 4 pcs. |
| Biryusa 14, 18 | Threaded connection | 14 mm | 4 pcs. |
| Turk 130, 131 | Combined | 13-14 mm | 4 pcs. |
| Built-in models | Specific | 10-12 mm | 2-4 pcs. |
Please note that the data in the table is for reference only, and the actual size may differ if your unit has had a compressor replaced or repaired at a service center.
Always check the size of the bolt face visually before starting work, so as not to strip the threads with the wrong wrench, which can create additional problems during future transportation.
Installing plugs and preserving components
After removing the transport bolts and rubber bushings, the resulting holes must be closed with special plastic plugs, which are usually supplied complete with documentation.
These plugs perform an important function: they prevent dust, moisture, insects and small objects from entering the housing that could damage electrical contacts or mechanisms.
If the plugs are lost or were not found in the kit, it is recommended to temporarily close the holes with pieces of clean rags or tape, but it is better to order original parts from the manufacturer.
⚠️ Attention: It is strictly forbidden to leave the holes open for a long time, as this violates the thermal insulation and can lead to corrosion of internal elements frames.
The most valuable elements in this situation are themselves transport bolts and the bushings, which must be carefully folded into a bag and put in a safe place, for example, in a refrigerator box.
The preservation of these parts is critically important, since Whenever moving, selling or servicing, you will again need to firmly fix the compressor, otherwise it will be damaged during transportation.
What to do if the bolts are rusty and cannot be unscrewed?
If you are faced with a situation where the bolts are stuck or rusted, do not use excessive force, which can break the key or damage the threads. Treat the joints with a penetrating lubricant (such as WD-40) and leave for 15-20 minutes. After the rust has soaked, try to carefully remove the bolt. If this does not help, it is better to call a technician so as not to damage the compressor tubes.
Typical errors when starting up for the first time
Many users make the mistake of believing that after unscrewing the bolts, the refrigerator can be immediately plugged in, but this is not entirely true for the correct operation of the unit.
There is a common misconception that oil the compressor must necessarily drain into the system if the refrigerator was lying during transportation, but modern models are more stable.
However, after installing and removing the fasteners, it is recommended to let the refrigerator stand in a vertical position position for a certain time before turning on.
- ❌ Error: Turning on the refrigerator immediately after removing the bolts without settling.
- ❌ Error: Trying to move the refrigerator by the top, which may disrupt the geometry of the doors.
- ❌ Error: Throwing out the transport bolts, what does impossible for safe transportation in the future.
- ❌ Error: Ignoring the noise level after starting, which may indicate that the tubes are touching the housing.
If, after removing the fastenings, you hear a strange metallic ringing or knocking sound when rocking slightly, this may mean that the compressor has moved and touched other elements structure.
Checking functionality after dismantling
After all manipulations with the bolts are completed and the plugs are installed, you can proceed to testing equipment, but this must be done gradually and carefully.
Plug in the refrigerator and during the first 15-20 minutes listen carefully to the operation of the motor: it should hum evenly, without sharp knocks, vibrations or metallic clangs.
Check whether the body vibrates excessively: slight vibration is acceptable, but if the refrigerator “walks” on the floor or rattles, perhaps it is uneven or not fully wedged.
Make sure that during the first hour of operation the internal shelves begin to cool, which indicates normal startup of the cooling cycle and circulation of the refrigerant.
If you notice that after removing the bolts, the refrigerator begins to operate louder than in the showroom, check whether the compressor tubes are touching each other or the cabinet walls.
Frequently asked questions (FAQ)
What happens if you forget to remove the shipping bolts and turn on the refrigerator?
If you turn on the refrigerator with the bolts clamped, the compressor will not be able to absorb vibrations, which will lead to rapid destruction of its suspension, broken tubes, freon leakage and motor failure. In addition, the noise level will be prohibitive.
Do you need to lubricate the bolts before reinstalling them when moving?
There is no need to specially lubricate the bolts, since they operate in a static mode during transportation. The main thing is to screw them cleanly into place and tighten them all the way to ensure rigid fixation.
Is it possible to transport the Biryusa refrigerator without shipping bolts?
It is strictly not recommended to transport the refrigerator without fixing the compressor with bolts. Even a short trip with the engine running or just dangling inside can lead to mechanical damage to the internal system.
Where can I get new bolts if the old ones are lost?
New bolts can be purchased in specialized stores of spare parts for household appliances or ordered from an authorized service center of the brand Biryusa, indicating the exact model of your refrigerator.
Does removing the bolts affect the manufacturer's warranty?
Removing the transportation bolts is a mandatory operating procedure and does not affect the warranty. On the contrary, turning on the device with bolts, leading to a breakdown, may be regarded by the service as a violation of the operating rules.
