High-quality installation of household appliances is the foundation of its long and silent operation. Many owners of new kitchen appliances make the mistake of believing that it is enough to simply bring the unit into the kitchen and plug it into an outlet. However, ignoring the horizontal position of the housing can lead to serious consequences, including increased wear of the compressor and violation of the tightness of the doors. Correct tilt ensures natural closing of the doors and correct outflow of oil in the system.
In this article we will analyze in detail how to level a two-chamber refrigerator, using available tools. You will learn why a slight roll back is important, how to adjust the support legs and what nuances exist for models of different brands, such as Indesit, Beko or LG. Compliance with these rules will help to avoid unnecessary noise and vibrations in the very first days of operation.
The installation process does not require calling a technician and takes only 15-20 minutes. The main thing is to understand the physics of the compression system and door hinges. If the unit is positioned crookedly, the load on the motor is distributed unevenly, which leads to overheating and eventual breakdown. Let's look at the main stages of preparation and direct adjustment.
Why it is important to maintain horizontality during installation
The main reason why it is necessary to strictly observe horizontality lies in the design of the compressor. Inside the motor-compressor there is oil, which must circulate throughout the system in strictly defined volumes. If the refrigerator is warped on one side, oil can accumulate in one of the circuits, depriving the compressor of lubrication. This leads to dry friction of parts and rapid failure of an expensive unit.
The second critical aspect is the operation of the doors. Modern models are equipped with an automatic closer system, but it only works correctly at a certain angle of inclination of the entire body. If the top is pushed forward, the doors will no longer seal tightly against the seal when open. This is fraught with constant loss of cold and freezing of ice.
⚠️ Attention: Installing a refrigerator without taking into account horizontal position may result in denial of warranty service. Service centers often check the installation level when diagnosing a compressor malfunction.
In addition, vibration is the main enemy of household appliances. When the unit is stable on all four supports, vibrations are damped by the housing and shock absorbers. If one of the legs hangs in the air or, on the contrary, is overloaded, a resonance occurs. Noise and hum during operation, this is the first sign that the equipment is installed incorrectly.
Necessary tools for checking and adjustment
Before starting physical impact on the equipment, you need to prepare the tools. The basic device is a building level. For household needs, a bubble model with a length of 40-60 cm is quite suitable. A more advanced solution would be a laser level, but it is rarely lying around in the closet of the average user.
You may also need a wrench or pliers if the legs are adjusted not manually, but through a threaded connection with a lock nut. In some models, for example, in rulers Samsung or Bosch, a special key is provided for the front legs, included in the kit.
- 📏 Construction level (bubble or laser) for checking planes.
- 🔧 Adjustable wrench or set open-end wrenches for fixing nuts.
- 🧤 Thick work gloves to protect your hands from sharp edges of the bottom.
- 📱 Smartphone with a level application (as a temporary alternative).
If you are moving a heavy unit on tiles, place a piece of thick cardboard or a special one under the legs transport platform so as not to scratch the coating. Rubber pads The legs should also not be damaged.
Surface preparation and preliminary check
The first step is assessing the installation site. The floor should have no visible bumps or holes. If you are installing equipment on linoleum, make sure there is no debris underneath that could create misalignment. To check, use a level by placing it on the floor in different directions.
After the refrigerator is put in place, do not rush to twist the legs. Allow the equipment to stand upright for at least 2-3 hours, especially if it was lying on its side during transportation. The oil should drain into the compressor crankcase. Only after this can you begin fine tuning.
Check the distance to the walls and furniture. For correct operation of the cooling system, a gap of at least 5-10 cm is required from the rear wall to the radiator. If the refrigerator is built into a niche, make sure that the ventilation openings are not blocked. Improper air circulation negates all leveling efforts.
| Check parameter | Normal value | Permissible deviation | Consequences of violation |
|---|---|---|---|
| Tilt back | 1-2 degrees | up to 3 degrees | Doors do not close themselves |
| Disk to the left/right | 0 degrees | not allowed | Door misalignment, noise |
| Gap to the wall | 5-10 cm | minimum 3 cm | Compressor overheating |
| Stability | All 4 legs on the floor | no | Vibration, humming |
Visually inspect the bottom. Some models have shipping bolts or clamps that must be removed before installation. Also check the condition of the adjustable supports: they should be screwed in and out without excessive force.
Step-by-step instructions: how to level the refrigerator
The adjustment process begins with the front supports. In most two-chamber models, it is the front legs that are adjustable, while the rear legs are often simple fixed wheels or stops. Your task is to lift the front part of the unit, creating the necessary obstruction back.
Take a level and place it on the top panel of the refrigerator parallel to the facade. The bubble should be strictly in the center or have a minimal deviation towards the walls (if the floor is flat). Then rotate the level 90 degrees to check the slope from left to right. There should be no deviations here at all.
☑️ Leveling algorithm
To adjust, grab the upper part of the front leg and rotate it. In some models Haier or Atlant the leg rotates entirely, in others there is an adjusting bolt under the bottom, which is turned with a key. Clockwise rotation usually raises the angle, counter-clockwise - lowers it.
⚠️ Attention: Do not lift the refrigerator by the door handle or the condenser from the back! This can cause thin metal to deform and tubes to rupture. Lean only on the side walls of the case.
After each adjustment, rock the case slightly. It should stand monolithically, without swaying. If the refrigerator stands on four points of support and does not swing, then you have achieved stability. If one leg does not reach the floor, twist it until it touches, but make sure that the opposite corner does not come off the surface.
Adjusting doors and checking tightness
The correct tilt of the body directly affects the operation of the doors. If installed correctly (tilt back about 2 degrees), the open door should close on its own if you release it at an angle of about 30-45 degrees. This is ensured by gravity and the design of the hinges.
If the doors do not close themselves, it means that the front part is lowered too low or the floor at the installation site slopes forward. In this case, you need to unscrew the front adjustable supports a little more. If the doors close too abruptly and with a bang, the angle of inclination may be too large.
Check the tightness of the seal around the entire perimeter. To do this, you can use a sheet of paper: clamp it between the door and the body and try to pull it out. The paper should come out with force. If in some place the paper flies out freely, it means that the seal is broken there, possibly due to the skew of the door leaf.
What to do if the doors are skewed?
If the body is level, but the doors hang crookedly, the hinges themselves will need to be adjusted. Loosen the hinge mounting bolts, level the door and tighten the bolts again. Some models have adjusting washers under the hinges.
Pay attention to the bottom edge of the door. It should not touch the base of the refrigerator or the floor covering when opening. If it touches, this is a signal that the refrigerator needs to be raised even higher, or (in rare cases) the height of the hinges adjusted.
Elimination of noise and vibration after installation
Even a perfectly level refrigerator can make sounds if it touches a wall or furniture. Vibration during compressor operation is transmitted to the housing, and from it to surrounding objects. Make sure there is an air gap between the back wall and the wall of the room.
Check that the condenser tubes are not touching each other from the back. Sometimes they may become dislodged during transportation. Lightly tapping the tubes against each other creates a characteristic metallic ringing sound. Carefully, trying not to bend them, separate the tubes or place a piece of foam rubber between them.
- 🔊 Check whether the compressor is vibrating on the shelf or other parts inside the niche (for built-in models).
- 📦 Make sure that inside the refrigerator bottles and containers do not touch each other friend.
- 🏠 Make sure that the floor under the refrigerator does not “play” (relevant for wooden floors).
If after all the manipulations there is still a hum, try placing special anti-vibration pads made of thick rubber under the legs. They dampen high-frequency vibrations and protect the floor covering from being crushed.
Frequent errors when installing refrigeration equipment
One of the most common mistakes is ignoring the manufacturer's instructions. The model data sheet Liebherr or Siemens may indicate specific requirements for clearances or angle of inclination that differ from the generally accepted ones. Always check the documentation.
The second mistake is alignment only “by eye”. Visually, the floor may appear level and the refrigerator may appear to be standing upright. However, the human eye is often deceiving. Using a level is a must, which takes seconds, but saves years of equipment service.
The third mistake is trying to level the refrigerator by placing cardboard, rags or wooden blocks under the legs. This is strictly prohibited! Such materials cake over time, absorb moisture and can cause a fire or sudden misalignment. Adjustment should be made only with standard screw supports.
⚠️ Attention: If the floor in the room has a strong natural slope (more than 3 degrees), using the refrigerator may not be possible without first leveling the floor with a screed. Under such conditions, the oil will not return to the compressor.
Also, do not forget about cleanliness. Before final installation, vacuum the area under the refrigerator. Dust and animal hair clogged under the bottom will make it difficult to access for future inspection of the legs and may cause an unpleasant odor.
FAQ: Frequently Asked Questions
Does the refrigerator need to be positioned perfectly horizontally or is it necessary to tilt it?
Perfect horizontal is required only along the left-right axis. Along the front-to-back axis, a slight tilt back is required (about 2 degrees) so that the doors close themselves under the influence of gravity and ensure tightness.
Is it possible to use a refrigerator if one leg is broken or lost?
It is not recommended to operate equipment with a missing support. This will lead to distortion of the housing, disruption of the compressor and doors. You can temporarily place a hard, non-deformable material (for example, a coin or a piece of tile), but it is better to order an original spare part.
Why does the refrigerator hum after installation, although it did not hum before?
Most likely, the balance is upset. Check that all four legs are firmly on the floor. If the unit swings, the compressor works with increased load, transmitting vibration to the housing. Also check the gap to the wall.
How often should you check the installation level of the refrigerator?
It is enough to check the level immediately after installation and then once a year during general cleaning. If you often wash the floor under the refrigerator and move it, check the position of the legs every time after returning the equipment to its place.
