Correct installation of household appliances is the foundation of its long and silent service. Many owners, having purchased a new unit, often ignore the leveling stage, relying on the fact that the floor in the apartment is initially flat. However, even a minimal tilt can cause serious problems in the future, from increased noise to premature wear of the compressor.
In this article we will take a closer look at why horizontal position the housing is so important for the operation of the cooling system. You will learn what tools are required for precise adjustment and how to avoid typical mistakes that even experienced craftsmen make during installation.
The alignment process seems simple only at first glance, but it requires care and adherence to the sequence of actions. Critical Let's look at this process in more detail.
Why is it important to keep the body horizontal
Ignoring the slope of the floor leads to uneven distribution of the weight of the unit. This creates excess pressure on one side of the frame, which over time can cause deformation of the frame or failure of the door seals. As a result, you risk getting a skewed door that will no longer close tightly.
Another important reason is the correct circulation of the refrigerant. Although modern systems are fairly stable, severe tilting can make it difficult for compressor oil to return to the crankcase. This is especially true for models with inverter compressorswhere the accuracy of the mechanisms is extremely high.
Finally, vibration. If the unit is positioned crookedly, the vibration from the running motor is not damped evenly. It is transmitted to the floor and walls, creating an annoying hum. Correct adjusting the supports allows you to completely eliminate this effect, making the operation of the equipment almost silent.
⚠️ Attention: If you notice that the refrigerator is standing on an uneven floor, do not try to place cardboard, wood chips or pieces of linoleum under the legs. These materials will wrinkle over time, and the equipment will warp again, and vibration will destroy the lining.
Positional stability also affects the operation of the system No Frost. If there is a strong distortion, condensation may not flow into the intended hole, but spread over the internal surfaces or flow out, forming puddles at the base.
Necessary tools for fine adjustment
Before starting work, you need to prepare a minimum set of tools. Without them, achieving an ideal result will be difficult, especially if the differences in floor height are significant. The main device here is a building level.
For most household tasks, a bubble level with a length of 40 to 60 cm is suitable. Shorter tools can give an error due to the small measurement base, and too long ones are inconvenient to place on the top cover of a narrow unit. You may also need an adjustable wrench or pliers if the adjustment is made with nuts.
In some cases, when the floor has significant uneven surfaces, the assistance of a second person may be required. One person will monitor the readings of the device, and the second will turn the adjusting screws, since the body of an empty refrigerator is light and can be pulled to the side.
Do not forget to prepare a clean rag. Before installing the device in place, it is recommended to wipe the floor and lower part of the case from dust to ensure better adhesion of the rubber pads of the legs to the surface. This will prevent unwanted sliding during operation.
Site preparation and initial inspection
The first stage is site preparation. Make sure the location you choose allows doors to open easily and has access to an electrical outlet. The distance to the wall should be at least 5-10 cm for normal ventilation of the condenser.
Carefully inspect the bottom of the unit. On most models, the front legs are threaded screw supports that are screwed into the body. Rear supports are often fixed or have a smaller range of adjustment. Your task is to compensate for uneven floors precisely due to the front screws.
If you are installing appliances in a kitchen with heated floors, make sure that the temperature in the installation area does not exceed the permissible values specified in the product data sheet. Overheating of the lower part can negatively affect the service life of the insulation and electronic components.
Check the integrity of the transportation bolts (if they are in the lower part for fixing the compressor) - they must be removed before turning on. Also remove all packaging materials, including tape and foam pads between the door and the body.
Step-by-step instructions for adjusting the legs
The alignment process requires a systematic approach. Don't try to set everything up by eye. Follow the algorithm to guarantee ideal results and stability of the structure.
☑️ Adjustment checklist
Start by installing the bubble level on the top panel of the refrigerator, placing it parallel to the front wall. Pay attention to the position of the air bubble. If it is offset to the left or right, the body is tilted to one side.
Using a wrench or your hands (if the design allows), begin to screw in or unscrew the front supports. To raise the angle, the screw must be screwed in (tighten), to lower it, unscrew it. Make small turns, constantly monitoring the change in the position of the bubble.
After leveling horizontally (along the front wall), move the tool perpendicularly to check the tilt back and forth. An important rule applies here: the refrigerator should have a barely noticeable tilt back. This is necessary so that the doors close independently under the influence of gravity.
| Type of support | Adjustment method | Tool | Feature |
|---|---|---|---|
| Threaded rod | Rotation around an axis | Wrench or pliers | Requires fixation with a lock nut |
| Screw support | Screwing into the body | Manually or with a key | Often hidden by a decorative base |
| Roller platform | Adjusting the height of the roller | Hexagon | Found in premium models |
| Fixed | Not adjustable | Absent | Used as a point supports |
When you have achieved the desired position, check the stability. Rock your body lightly. It shouldn't wobble. If there is play, it means that one of the legs does not touch the floor, and the procedure must be repeated more carefully.
Nuances for models with the No Frost system
Refrigerators with the system No Frost have a more complex internal architecture, including fans and additional moisture removal channels. For them, installation accuracy is critical, since condensate is discharged into a special tray above the compressor by gravity or using a pump.
If the angle of inclination is incorrect, water may not enter the evaporator, but accumulate inside the housing or leak out. This leads to the formation of ice in unintended places and increased humidity in the chamber.
⚠️ Attention: In models with water and ice dispensers on the door, misalignment can disrupt the operation of the mechanical liquid supply valves. Make sure that the hoses inside are not pinched due to housing deformation.
It is also worth considering the weight of the unit filled with products. An empty refrigerator may stand perfectly, but under a load of 50-70 kg the legs may turn or sag a little. Therefore, after the first load of products, it makes sense to re-check the level after 2-3 days.
What to do if the floor is very crooked?
If the difference in floor height exceeds the adjustment range of the standard legs (usually 2-3 cm), use a metal platform stand for the entire refrigerator. It is not recommended to use wooden blocks due to their hygroscopicity and tendency to rot.
Typical installation errors
One of the most common mistakes is trying to level the equipment by placing something under the rear wheels or fixed supports. As already mentioned, this is a temporary solution that quickly loses its effectiveness. In addition, this can damage the floor covering.
Another mistake is excessively twisting the front legs. If you twist them too much, the fulcrum point shifts and stability decreases. In extreme cases, the thread may jump out of its socket and the leg will fall off, causing the heavy unit to fall.
Do not forget about the decorative base. Many models have a plastic strip installed at the bottom that hides the compressor and legs. Before adjusting, it must be removed or moved, otherwise you will not be able to get to the adjustment elements, or you will damage the plastic.
Ignoring the manufacturer's instructions is another recipe for problems. The manual for specific models, for example Liebherr or Atlantmay have their own specific requirements for clearances and angles of inclination, which differ from generally accepted standards.
Checking the installation quality and final recommendations
After completing all adjustments, conduct a final test. Open the refrigerator door to a 45 degree angle and release. It should close smoothly and confidently on its own. If the door stays in place or slams too hard, the angle of inclination is incorrect.
Plug in the unit and listen. In the first minutes of operation, noise may be noticeable, but it should be uniform. If you hear rattling or knocking noises, check to see if the vibration tubes are touching the cabinet or walls. Sometimes, to eliminate the noise, it is enough to slightly change the position of the unit, moving it a centimeter.
Make sure that all the locknuts on the adjusting screws are tightly tightened. They serve to fix the position of the leg so that it does not unwind from vibration during operation. This is especially important for households with active children or pets.
Is it possible to install a refrigerator on a sloping floor without adjusting the legs?
It is strictly not recommended. Operating on a sloping floor will cause the compressor to skew, prevent oil and refrigerant circulation, and cause the doors to keep opening. This will shorten the service life of the equipment significantly.
Why does the refrigerator wobble, even if the floor is flat?
Most likely, one of the four supports does not touch the surface. This often happens when the floor itself is uneven (lumps, pits) or when the height of the legs is incorrectly adjusted. It is necessary to re-set the level.
Does it need to let the refrigerator sit after transportation before leveling?
Yes, if the refrigerator was transported lying down, it needs to stand upright for 2 to 8 hours (depending on the time of year and model) for the oil to drain into the compressor. You can equalize the level immediately, but connect it to the network only after settling.
Does the installation level affect electricity consumption?
Indirectly - yes. If the doors do not close tightly due to misalignment, the cold goes away, the compressor runs more often and longer, which increases energy consumption. Also, poor ventilation due to improper clearance near the wall affects the efficiency of heat transfer.
