Buying a new refrigerator LG is always a joyful event, marking a kitchen renovation and improved food storage conditions. However, between the moment the box is delivered to the apartment and the full operation of the unit lies a critical stage - correct installation. Many owners mistakenly believe that it is enough to simply bring the device into the kitchen, remove the packaging and plug it into an outlet, ignoring the technical nuances specified in the manual. Incorrect installation can lead to increased noise, vibration, rapid wear of the compressor, or even leaks if the model is equipped with a system with an ice maker. In this article, we will look in detail at how to prepare a room, level the equipment and put it into operation so that it serves you for many years without failures.
Incorrect installation can lead to increased noise, vibration, rapid wear of the compressor, or even leaks if the model is equipped with a No Frost with ice maker. In this article we will look in detail at how to prepare a room, level the equipment and put it into operation so that it serves you for many years without failures.
Compliance with all technological clearances and transportation rules is foundation a long service life of your equipment. Even the most expensive model can fail ahead of time if you ignore the basic requirements for ventilation and stability.
Preparing the room and choosing a location
The first step is to carefully select a location for placing refrigeration equipment. The place should be protected from direct sunlight, as ultraviolet radiation negatively affects the plastic of the case and can cause fading or deformation of the seals. In addition, it is not recommended to install equipment in close proximity to heating devices, such as central heating radiators, ovens or gas stoves.
If it is impossible to avoid proximity to it, it is necessary to ensure reliable thermal insulation. To do this, a special screen is installed between the refrigerator and the heat source or an increased distance is maintained. It is also important to consider that the floor at the installation site must be level and support the significant weight of the unit filled with products.
A critically important parameter is to ensure correct air exchange. Heat exchangers located on the rear wall or in the base must be freely blown with air for effective heat removal. Violation of this rule leads to overheating of the compressor and increased electricity consumption.
- 📏 The minimum distance to the rear wall should be at least 5-7 centimeters for free air circulation.
- 🔥 The distance to the stove or oven should be at least 30 centimeters, or installed heat-insulating shield.
- 💡 Lighting in the installation area should not heat the upper part of the case, especially if the control panel is located there.
⚠️ Attention: It is strictly forbidden to install the refrigerator in a niche without ensuring air inflow and outflow, as well as in unheated rooms where the temperature drops below +10°C, as this violates the viscosity of the compressor oil.
Transportation and unpacking of equipment
After delivering the equipment to its destination, it is necessary to give it time to acclimatize, especially if it was transported in the cold season. Sudden temperature changes can cause condensation to form inside electrical circuits, which will result in a short circuit when first turned on. Experts recommend waiting 2 to 4 hours before unpacking.
Remove the transport packaging carefully, using a utility knife or scissors, being careful not to damage the paintwork of the case. Pay special attention to removing the tape from the doors - do it smoothly so as not to tear off the handles or decorative elements. There may be shelves, trays and documentation inside the camera that need to be removed before installation.
It is important to check the completeness and absence of external mechanical damage. If you find dents or chips, it is better to fix them in the presence of delivery service employees. It is also worth inspecting the condenser (black grille at the back) for the integrity of the tubes.
Transportation in a horizontal position is acceptable, but requires special care during subsequent vertical placement. Oil from the compressor may have flowed into the cooling circuit, and it needs time to drain back into the engine crankcase.
Alignment and adjustment of supports
A stable position of the refrigerator is the key to quiet operation and proper closing of the doors. If the device is placed on an uneven floor, the doors may open spontaneously or, conversely, not fully adhere to the body, which breaks the seal of the chamber. To correct the position, adjustable supports located in the front lower part of the unit are used.
The leveling process is carried out by rotating the support legs. In some models LG to do this, it is enough to turn the leg itself by hand, in others you may need a key or a screwdriver. The goal is for the front legs to be twisted out a little more than the rear legs, creating a slight tilt of the body back.
This tilt angle ensures that the doors automatically close under the influence of gravity if they are open less than 45 degrees. This also reduces the stress on hinges and seals. You can check the horizontality using a building level placed on the top cover or inner shelf.
- 🔧 The front supports should be unscrewed so that the body leans back by about 2 degrees.
- 🚪 The door should close tightly on its own if released in the half-open position.
- ⚖️ The device should not wobble when lightly pressing on the corners of the case.
☑️ Checking the installation
Do not forget that after being fully loaded with products, the weight of the unit will increase and the position of the supports may change slightly. Therefore, it is better to carry out the final adjustment after the chambers are filled.
Connection to the water supply (for models with an ice maker)
Owners of advanced models LG with the function of an automatic ice maker and water dispenser must arrange a connection to the cold water supply system. This process requires caution, since any error in the tightness of the connections can lead to flooding of the kitchen.
For connection, use a special hose included in the kit and a shut-off valve. It is best to tap into the water supply through a tee installed under the sink. It is important to use only food-grade materials and fittings intended for drinking water supply to avoid harmful substances getting into the water.
After connecting all the elements, you must open the valve and carefully check the joints for leaks. It is recommended to place a dry cloth under the connections and wait 10-15 minutes. If the paper remains dry, then the system is sealed.
| Parameter | Requirement | Note |
|---|---|---|
| Water pressure | from 1 to 7 bar | High pressure requires a reducer |
| Water temperature | +4...+30°C | Cold water only |
| Hose diameter | 1/4 inch | Standard for refrigerators |
| Pipe material | Copper or plastic | Steel is not recommended |
⚠️ Attention: Before the first water intake, it is necessary to drain the first 2-3 liters of liquid in order to flush the system and remove coal dust from the new one filter.
How to replace a water filter?
To replace the water filter, turn it counterclockwise until it stops, remove the old cartridge, remove the protective cover from the new one and insert it until it clicks. After replacement, also spill water.
First start-up and setting temperature modes
After the refrigerator is installed, leveled and connected (if required), you can proceed to the first start-up. Insert the plug into a grounded outlet with a voltage of 220-240 volts. Do not use extension cords and tees, since the refrigerator is an energy-intensive device and requires reliable contact.
Immediately after turning on, the compressor may not start working immediately, but after a few minutes - this is normal, the electronics conduct self-diagnosis. The indicators on the control panel will light up, and after a while the standard temperature regime will be established. It is recommended not to load the chamber with food on the first day so that the unit gains cold on empty.
Modern models LG equipped with intelligent control systems, such as Smart Diagnosis quick freezing modes. Check out the settings menu: usually the optimal temperature for the refrigerator compartment is +3...+4°C, and for the freezer -18°C and lower.
It is important to check the operation systems No Frost. After several hours of operation, no ice or drops of water should form on the walls. If you notice excessive freezing, check the tightness of the doors and the absence of obstacles to air circulation inside the chambers.
Typical installation errors and their consequences
Even careful study of the instructions does not always guarantee an ideal result, and users often make repeated mistakes. One of the most common is ignoring the removal of transport bolts or compressor clamps, if they are provided for in the design. This leads to strong vibration and noise when the engine is running.
Another common mistake is installing the refrigerator close to the wall or in a cabinet niche without gaps. As a result, heat is not removed, the refrigerator works for wear, trying to reach the set temperature, which reduces the life of the compressor by several times. It is also dangerous to place heavy objects on top of the device, which can disrupt the geometry of the case.
Some users try to speed up the defrosting or cleaning process by using hair dryers or sharp objects to chip ice. This is strictly prohibited, as the evaporator can be damaged and the refrigerant will escape, making repairs economically unfeasible.
- ❌ It is forbidden to turn on the device immediately after horizontal transportation without settling.
- ❌ Do not wash the internal plastic parts with hot water or aggressive chemicals.
- ❌ It is not recommended to overload the shelves beyond the limit specified in the product passport.
⚠️ Attention: Technical characteristics and installation requirements may vary depending on the specific series of the refrigerator. Always check the official user manual included with your model.
How long should you wait before using it for the first time?
If the refrigerator was transported in an upright position, It is enough to wait 2-3 hours for the temperature sensors to stabilize. If the device was lying on its side, the waiting time increases to 4-8 hours so that the compressor oil completely drains into the engine crankcase.
Why does the LG refrigerator hum or vibrate?
Most often the reason lies in incorrect alignment of the supports. Make sure that all four legs are firmly in contact with the floor and that the body is tilted back slightly. Also check whether the condenser pipes are touching the wall or other objects.
Is it possible to place a refrigerator on a heated floor?
Manufacturers do not recommend installation on floor heating systems, as this disrupts the temperature regime of the compressor and increases energy consumption. If there is no alternative, you must use a thermally insulating stand.
What to do if the door does not close tightly?
Check whether food or dishes are preventing it from closing. If the compartment is empty, try adjusting the height of the front supports by lifting the front of the refrigerator. Also check the cleanliness of the sealing rubber.
