Modern refrigerators Leran have proven themselves to be reliable and functional units that can ensure long-term preservation of food freshness. However, in order for the equipment to work with maximum efficiency and not fail at the most inopportune moment, the owner needs to understand the principles of its operation. Correct initial setting of parameters and compliance with operating rules is the key to long service life of the compressor and preservation of the properties of the internal coating of the chambers.
Many users are faced with questions about how to correctly set the temperature or what to do if ice freezes in the freezer. The answers to these questions lie in the design features of a particular model, be it a system No Frost or static cooling Direct Cool. In this material, we will analyze in detail all aspects of interaction with your refrigerator, from the first turn on to fine-tuning the microclimate.
You should not ignore the basic recommendations of the manufacturer, since even minor violations can lead to increased energy consumption. Understanding how your Leranworks will allow you to avoid common mistakes and save your family budget on utilities. Let's look at the key stages of setup and maintenance.
First turn on and initial setup
After delivering the refrigerator Leran home, it is critical not to connect it to the power supply immediately. During transportation, the unit may have been subjected to shaking, tilting, or even briefly lying down, which causes compressor oil to flow into the piping system. If you start the engine immediately, the oil can create a hydraulic shock, which will lead to serious damage to the compressor.
It is necessary to allow the equipment to stand in a vertical position. The settling time depends on the ambient temperature: in winter it is recommended to wait up to 4-6 hours, and in summer 2-3 hours is enough. Only after the refrigerant and oil have completely returned to the compressor crankcase can you carefully insert the plug into the socket.
⚠️ Attention: Do not use extension cords or tees to connect the refrigerator. A direct connection to a working outlet that has a grounding guarantees stable operation of the electronics and protection from power surges.
After switching on, the device will start working, but you cannot immediately load it with products. An empty chamber takes time to reach the desired temperature. Usually this process takes from 6 to 12 hours, depending on the volume of the chambers and the ambient temperature in the room.
☑️ Initial startup of the refrigerator
Managing temperature conditions in the refrigerator
One of the main functions that the refrigerator is equipped with Leranis the ability to adjust the cooling intensity. In most models, control is carried out through a mechanical regulator or electronic panel. A mechanical thermostat is usually a rotary knob with divisions from 1 to 5 or from Min to Max.
It is important to understand that the number on the regulator does not indicate degrees, but the power of the compressor. The higher the value, the lower temperature inside the chamber. For everyday food storage, the handle position in the middle of the scale or the value “3” is considered optimal. This ensures a balance between food safety and energy consumption.
If your model has an electronic control panel, adjustments are made by pressing the Temp or Modebuttons. Electronics allow you to set the exact temperature in 1-degree increments. The recommended mode for the main chamber is from +2°C to +5°C.
You should not set minimum temperature values unless absolutely necessary. Working at the limit of capabilities forces compressor to function almost without interruption, which significantly reduces its resource and increases electricity bills.
Setting the freezer compartment and Fast Freeze mode
Freezer compartment in refrigerators Leran designed for deep freezing and long-term storage of products at temperatures of -18°C and below. For quick freezing of large volumes of fresh food (meat, fish, berries), the function Fast Freeze or "Super Freeze" is intended.
When this mode is activated, the compressor goes into continuous operation, ignoring the thermostat signals to stop. This allows you to quickly reduce the temperature of food, preventing the formation of large ice crystals, which destroy the structure of tissues and lose juice during defrosting.
However, you cannot use the mode Fast Freeze always. This is an emergency mode for short-term use (usually no more than 24-48 hours). After the products have frozen, the function must be turned off manually or wait for automatic shutdown if the model supports a timer.
| Operating mode | Temperature | Duration of use | Purpose |
|---|---|---|---|
| Standard | -18°C ... -20°C | Continuous | Frozen food storage |
| Eco | -15°C ... -16°C | Long-term | Energy saving |
| Super freezing | -24°C ... -26°C | Up to 48 hours | Quick freezing of fresh food |
| Shutdown | Above 0°C | Short-term | Defrosting or washing |
You should remember that loading a large amount of warm food into the freezer without turning on the quick freezing mode can lead to a temporary increase in the temperature of the supplies already lying there, which will negatively affect their safety.
Defrosting systems: No Frost and drip
Refrigerators Leran can be equipped with two types of defrosting systems: drip (Direct Cool) and automatic No Frost. Understanding the differences between them is necessary for proper care of equipment.
In models with a drip system, an evaporator is located on the back wall of the refrigerator compartment. As the compressor operates, frost forms on it. When the compressor turns off, the frost melts and the water flows down a groove into a special hole, going into a tray above the motor, where it evaporates. The user only needs to periodically (once every 6-8 months) defrost the freezer manually.
The system No Frost (or Full No Frost) works differently. The fan constantly circulates dry, cold air through the chambers, and the evaporator is hidden and automatically defrosts every few hours. In such refrigerators, frost does not form at all, and manual defrosting is required extremely rarely, mainly only for hygienic washing.
⚠️ Attention: In refrigerators of the No Frost system, it is strictly forbidden to seal the ventilation holes inside the chamber or tightly fill the space at the back wall with food. This will disrupt air circulation and lead to spoilage of food.
Regardless of the type of system, it is important to keep the drainage hole clean. If it becomes clogged with crumbs or mold, the water will stop draining and will begin to accumulate at the bottom of the refrigerator or under the vegetable drawers.
Why does ice still appear in No Frost?
Ice in the No Frost system can only appear in two cases: if the defrost heating element or sensor is faulty, or if the door does not fit tightly and into the chamber humid air constantly enters from the room.
Arrangement of products and storage organization
Refrigerator operating efficiency Leran directly depends on how you place the products inside. Cold air should circulate freely between the products. If the shelves are packed to capacity, the temperature in different zones can vary greatly.
There is a “thermal triangle” rule: the coldest zones are at the back wall and on the lower shelves, and the warmest ones are on the door and in the upper drawers (depending on the model). Distribute products according to their storage requirements.
- 🥩 Bottom shelves: Ideal for raw meat, fish and poultry, as they have the lowest temperature, preventing the growth of bacteria.
- 🥛 Middle shelves: Designed for ready meals, dairy products, eggs and sausages products.
- 🥦 Bottom drawers: Special high humidity zone for vegetables, fruits and herbs.
- 🧃 Door shelves: The warmest place, suitable for sauces, drinks and food products preservatives.
Do not place hot pots inside the refrigerator. This causes a sharp jump in temperature, makes compressor work for wear and leads to moisture condensation, which can turn into ice.
Care, cleaning and prevention
Regular maintenance of the refrigerator Leran extends its service life and prevents the appearance of unpleasant odors. It is recommended to carry out cleaning at least once every 3-4 months, and more often if necessary.
To wash the internal surfaces, use a soft sponge and a warm solution of baking soda or low-concentrated soap. Use abrasive powders, chlorine-containing products and aggressive chemicals is prohibitedas they can damage the plastic housing and rubber seals.
Pay special attention to the rubber seals on the doors. Over time, dirt and grease accumulate on them, causing the door to no longer fit tightly. Wipe them with a soft cloth soaked in warm water. To maintain the elasticity of the rubber, you can lubricate it with silicone grease or a special rubber care product every six months.
External surfaces, especially if the refrigerator has coating Anti-fingerprint (anti-fingerprints), should be wiped with special products for stainless steel or with a damp microfiber cloth. This will preserve the neat appearance of the equipment for many years.
Frequently asked questions and answers (FAQ)
Why does the Leran refrigerator make loud sounds or gurgle?
Gurgling and overflowing of liquid is the normal sound of refrigerant moving through the pipes of the system, especially in models s No Frost. The clicking noise may come from the thermostat when turning on/off or from the plastic during thermal expansion. If the noise is not accompanied by vibration or hum, there is nothing to worry about.
What to do if ice forms on the back wall of the refrigerator?
If you have a drip system, a small layer of frost while the compressor is running is normal; it should melt when turned off. If the ice does not melt or there is too much ice, check to see if the drainage hole is clogged and make sure that you do not place food close to the back wall.
How to defrost the freezer correctly?
Unplug the refrigerator, remove all food and open the doors. Do not use a hair dryer, knife or other tools to chip the ice as this may damage the evaporator. Wait for natural melting, collect the water, wash the chamber and turn on the device again after 1-2 hours.
Is it possible to transport the Leran refrigerator lying down?
Manufacturers do not recommend transportation lying down, but if necessary, the unit can only be laid on its side (usually on the right, but it is better to check in the instructions for the specific model). After transportation in a horizontal position, the standing time before turning on should be increased to 12-24 hours.
