When installing yourself or When moving large household appliances, owners are often faced with incomprehensible design elements, the purpose of which is not obvious without technical documentation. One of these elements is back stop, which can be found on the back wall or in the lower part of the body of refrigerators of the brand Atlant. Many users mistake this part for a transport lock, intended only for protection during transportation, and rush to dismantle it immediately after unpacking.
However, haste in this case can lead to unstable operation of the unit and the appearance of extraneous sounds. Back stop in refrigerators Atlant performs a critical function in stabilizing the position of the compressor and the entire refrigeration chamber relative to the walls and floor. Understanding the principle of its operation will allow you to avoid common installation mistakes and extend the service life of the motor.
In this article we will analyze in detail the design features of this unit, consider typical problems that arise from incorrect adjustment, and give step-by-step instructions for setting it up. You will find out why the gap between the back wall and the wall of the room should be at least 5-7 centimeters, and how exactly the stop helps to comply with this requirement in small-sized kitchens.
Design features and purpose of the stop
Refrigerators Atlant, like many other models of modern household appliances, are equipped with a stabilization system, which often goes unnoticed. Rear stop is a plastic or metal element integrated into the back panel or base frame. Its main task is to prevent the body from moving forward when opening the doors, especially when they are equipped with closers or the seals have high resistance.
The design of the stop is designed to transfer force from the door leaf to a fixed support (wall or floor), eliminating tipping unit. In some models Atlant this element also serves as a limiter that prevents the equipment from being moved too close to the wall, which is necessary for air circulation. Ventilation capacitor is a key factor in the durability of the compressor, and the lack of clearance can lead to overheating.
It is important to note that in a number of modifications the stop is combined with the transport bolt fastening system, which causes confusion. However, unlike temporary clamps, this element does not need to be removed after installation. It is part of the standard positioning system, which ensures geometric stability of the case during operation.
⚠️ Attention: Removing the standard back stop may lead to instability of the refrigerator. When a heavy door is opened abruptly, the unit may tilt forward, which creates the risk of objects falling from the top shelf or even the refrigerator itself overturning on the user.
Engineers Atlant have provided various options for the design of stops depending on the series of the refrigerator. In some cases it is a hard plastic tab, in others it is an adjustable leg or rubber pad. Understanding the type of your stop will help you correctly adjust the position of the equipment.
The influence of the stop on the operation of the compressor and the noise level
One of the main reasons for vibrations and humming is incorrect positioning of the housing, for which the back stop is often responsible. The refrigerator compressor Atlant during operation creates mechanical vibrations that are transmitted to the housing. If the unit is uneven or skewed, resonanceoccurs, which increases the noise significantly.
The back stop helps fix the upper part of the body, preventing it from swinging. When the refrigerator rests tightly and correctly against the wall (through the provided gasket or at a certain distance), the amplitude of vibration of the rear wall is reduced. This is especially true for models with inverter compressorsthat are sensitive to the quality of the installation.
In addition, the emphasis indirectly affects the operation of the condensate drainage system. If the tilt is incorrect, caused by lack of support at the back, water may not flow into the evaporator tray, but may flow out onto the floor. Adjusting the position of the housing taking into account the back stop ensures the correct angle of inclination necessary for gravity flow of the liquid.
- 🔇 Reducing vibration levels by fixing the upper point of support of the housing.
- ❄️ Ensuring correct heat transfer by maintaining a gap at the rear wall.
- 💧 Prevention condensate leakage by controlling the angle of inclination of the unit.
- 🛡️ Protection of wall coverings from damage when opening doors.
Transport clamps vs standard stop
A common mistake made by users is confusion between the standard back stop and the shipping bolts. The transport bolts fix the compressor or moving parts inside the housing so that they are not damaged by shaking during delivery. They must be unscrewed before connecting the device to the network.
The standard one back stop, which is discussed in this article, is part of the structure intended for use. It doesn't come off. You can visually distinguish them by their location: the shipping bolts are usually located at the bottom, closer to the compressor, and have a threaded connection with rubber bushings.
If you are in doubt whether the protruding part is a retainer, refer to the instructions Atlant for your specific model. In most cases, in the place of the removed shipping bolts, there are holes that need to be closed with plugs to avoid loss of cold and dust.
How to distinguish a shipping bolt?
The shipping bolt usually has a large head, often yellow or red, and passes through the body, fixing the springs compressor. The standard stop is a plastic protrusion or rubber foot integrated into the panel and does not have a thread for unscrewing.
Incorrectly removing the standard stop can cause the refrigerator to lose its fulcrum. This is especially critical for narrow models where the center of gravity is shifted. In such cases, even a slight force on the door can lead to tipping over.
Instructions for adjusting the position of the refrigerator
Correct installation of the refrigerator Atlant requires compliance with several technical conditions, and the back stop plays an important role here. Before starting work, make sure that the floor is level and the wall against which the equipment will stand is able to withstand load and vibration.
To adjust, you will need a building level and, possibly, a wrench to adjust the support legs. The process of adjusting the position of the body, taking into account the back stop, is as follows:
☑️ Checking the installation of the refrigerator
First install the unit in the intended location. Check the gap between the back wall and the room wall. If your model has a rear stop-limiter, it will prevent the refrigerator from being pushed in close. This is normal and necessary for air circulation.
Next, use a level, applying it to the top panel and side walls. Adjust the height of the front and rear support legs until the level bubbles are in the center position. It is important that the refrigerator stands firmly and does not wobble when lightly pressing on the corners.
Adjustment sequence:1. Loosen the locknut on the support leg (if equipped).
2. Rotate the adjusting screw to change the height.
3. Check the level.
4. Tighten the locknut to fix the position.
After adjustment, check the operation of the doors. They should open freely, but when released in the half-open position (approximately 30-45 degrees), they should close on their own due to the slight tilt of the body back. The back stop should not interfere with this process, but should prevent the entire body from moving forward.
Typical problems and methods for eliminating them
During operation, owners of refrigerators Atlant may encounter a number of problems associated with improper interaction stop and wall surface. One of the common complaints is the appearance of knocking or rattling when the compressor operates. This may mean that the stop is pressed too tightly against the wall or, conversely, leaves too much play.
If the stop is plastic and has become deformed or cracked over time, it must be replaced. Operating a refrigerator with a damaged stabilization element is unacceptable, as this leads to increased vibration of the entire box. In some cases, sticking an additional layer vibration-isolating material (for example, rubber or thick felt) onto the contact pad of the stop helps.
There is also a problem when, due to the lack of a stop or its incorrect setting, the refrigerator begins to “crawl” forward each time the door is opened. This can be treated by re-adjusting the support legs: the front legs need to be unscrewed a little more to ensure a stronger tilt of the body back.
| Problem | Probable cause | Solution |
|---|---|---|
| Strong vibration of the body | Lack of contact between the stop and the wall or uneven floor | Adjusting the legs, checking the gap |
| The refrigerator moves forward | Insufficient tilt of the body back | Increase the height of the front supports legs |
| Knock when closing the door | Hard contact of the stop with the wall | Glue the rubber gasket on the stop |
| Overheating of the compressor | Too small gap at the back walls | Move the refrigerator, check the stop-limiter |
Do not ignore extraneous sounds. Prolonged vibration can cause internal components, such as the heat exchanger tubes or the compressor itself, to become loose, resulting in costly repairs.
Maintenance of fasteners and stability
Although the backgauge does not require special maintenance, regular checks of its condition will not be superfluous. During general cleaning, when you move the refrigerator Atlant to wash the floor or back panel, inspect the contact surface of the stop. There should be no dirt, dust or traces of mold on it that may form due to condensation.
Contamination in the stop area can become a source of an unpleasant odor or even cause corrosion if the stop is metal. Wipe the element with a damp cloth and neutral detergent. Also check if cracks have appeared on the plastic.
Once every six months it is recommended to check the stability of the refrigerator. Rock your body lightly (without using too much force). If you feel play that has appeared over time, the adjusting legs may have sagged or the geometry of the floor has changed. Timely adjustment will help avoid problems in the future.
⚠️ Attention: When moving the refrigerator away for cleaning, be careful. Do not rest your entire weight on the back wall or condenser grille. Pull the unit by the lower part of the side walls or special handles, if provided by the design.
Compliance with simple operating rules and periodic monitoring of the condition of the supporting elements guarantee quiet and durable operation of your refrigerator Atlant. Remember that correct installation is the foundation for the reliable operation of any complex equipment.
Frequently asked questions (FAQ)
Is it necessary to remove the back stop when installing the Atlant refrigerator for the first time?
No, the standard back stop does not need to be removed. It is part of the structure to provide stability and proper clearance for ventilation. Only the transport bolts should be removed, which are usually marked with bright stickers or are indicated in the instructions as temporary fasteners.
The refrigerator is crooked, although the legs have been adjusted. Could it be the stop?
Yes, if the back stop protrudes too much or, conversely, is deformed, it can interfere with the correct installation of the case. Check that the fence is evenly touching the wall. If the wall is uneven, you may need to compensate for this by adjusting the front legs or using a pad for the stop.
What is the best pad for the stop if it starts to knock?
The optimal solution would be to use a self-adhesive rubber tape, felt or special vibration-isolating material. Do not use hard materials (wood, metal), as they will not dampen vibration and may increase knocking.
Can the lack of a back stop lead to compressor failure?
Indirectly - yes. The lack of support leads to increased vibration of the housing, which is transmitted to the internal units. Long-term operation under conditions of resonance can cause fatigue of the metal tubes, breakage of contacts or destruction of the compressor suspension, which will lead to its failure.
Where can I find the original stop if mine is broken?
Original spare parts for refrigerators Atlant can be purchased at authorized service centers of the brand or specialized stores of spare parts for household appliances. When ordering, be sure to indicate the exact model of your refrigerator, since the configuration of the stops may differ in different series.
