Introduction of equipment DEXP
Correct initial setup of a household refrigerator is the foundation for its durable and silent operation for many years. After delivering the unit to the kitchen and removing the shipping tapes from the outer surface, it is necessary to allow the compressor and oils to stand in a vertical position. This adaptation period usually takes from two to four hours, which allows the refrigerant system to stabilize before the first start.
When you turn on the device, you will notice that modern models DEXP immediately begin to increase in temperature, which is indicated by the operation of the compressor and the absence of sound notifications on the control panel. It is important not to load the chambers with products immediately, but to allow the equipment to reach the specified cooling mode when empty. This will take several hours, during which you should not open the doors frequently.
Successful initial calibration all systems ensure that food is stored under optimal conditions, preserving freshness and vitamins. Owners often neglect basic placement rules, which can lead to motor overheating and increased power consumption.
Installation and initial start-up rules
Before you begin fine-tuning temperature conditions, you should make sure that the physical placement of the device is correct. The refrigerator must stand on a flat surface, which is checked by the building level. Adjusting the support legs allows you to compensate for uneven floors, ensuring that the door fits tightly to the body and the magnetic seal closes correctly.
The distance from walls and furniture plays a critical role in air circulation around the condenser. If the unit is built into a niche or stands close to the wall, the efficiency of heat transfer decreases, forcing compressor to work with increased load. This can lead to rapid wear of parts and increased electricity bills.
After turning on the power, the control panel may blink or beep, which is normal behavior of electronics at startup. Some models require manual activation of cooling if the device was in demo mode in the store.
⚠️ Attention: Never plug in the refrigerator immediately after transporting it in a horizontal position. The oil from the compressor must completely drain back into the crankcase, otherwise water hammer and failure of the unit may occur.
Make sure that the outlet to which the equipment is connected has reliable grounding. The use of extension cords or tees is not recommended, as they can cause poor contact and heating of the wiring during peak loads at engine start.
Control of electronic panel and display
Modern refrigerators DEXP are equipped with convenient touch or push-button control panels located on the outside of the door or inside the camera. The interface may differ depending on the model, but the logic of operation remains similar for most devices of this brand. The main screen displays the current temperature in the refrigerator and freezer compartments.
To change parameters, a button with a thermometer image or caption is usually used Temp. A short press allows you to select a compartment, and subsequent presses change the numerical value. Some models require holding the button for 3 seconds to unlock the panel from accidental pressing by children.
- 🔹 The button Freezer is solely responsible for setting the freezer compartment.
- 🔹 The indicator Eco signals the economy mode operation.
- 🔹 The snowflake symbol indicates the fast freezing mode.
- 🔹 Flashing numbers may indicate that the temperature is outside the acceptable limits.
If the display goes out or stops responding to presses, the protection may have tripped or there has been a failure in the electronic module. In such cases, completely disconnecting the device from the network for 10–15 minutes helps. After turning on again, the system should reboot and restore the factory settings.
Optimal setting of temperature conditions
The main task of the user is to set parameters in which the products do not spoil, but also do not freeze unnecessarily. For the main refrigerator compartment, the standard range is +2 to +5 degrees Celsius. It is at these values that the growth of bacteria slows down, but the structure of the products is not disturbed.
In the freezer, the temperature should be below -18 degrees. This value ensures long-term storage of meat, fish and semi-finished products without loss of their taste. If you plan to freeze large volumes of fresh food, it is recommended to temporarily activate the mode Super Freeze, which lowers the temperature to -24 degrees.
⚠️ Attention: Too low a temperature in the refrigerator compartment (below 0 degrees) will lead to freezing of vegetables and fruits, as well as the formation of ice on the back wall.
Adjustment is carried out smoothly, in steps of one degree. You should not expect an instant change in the climate inside the chambers - the compressor needs time to stabilize the new parameters. Frequently changing settings disorients the automation and leads to excessive energy consumption.
☑️ Checking the temperature conditions
Pay attention to the distribution of cold: it is usually warmer on the upper shelves, and colder on the lower ones. Place perishable products, such as meat and fish, on the lower levels or in the freshness zone, if provided by the design of your model DEXP.
Special functions and additional modes
Many refrigerator models offer advanced functionality for various use scenarios. The “Vacation” mode allows you to switch the refrigerator compartment to an economical operating mode, while the freezer continues to function normally. This is an ideal solution for long business trips. DEXP offer advanced functionality for various use cases. The “Vacation” mode allows you to switch the refrigerator compartment to an economical operating mode, while the freezer continues to function normally. This is an ideal solution for long business trips.
The quick freezing function is useful when you bring home a lot of fresh food. It turns on the compressor at maximum power for several hours. After automatic or manual disabling of this mode, the device returns to standard settings.
| Operating mode | Description of function | Recommended time of use |
|---|---|---|
| Eco | Economical energy consumption | Constantly, with standard loading |
| Super Freeze | Intensive freezing | 2-4 hours after loading the freezer |
| Vacation | Vacation mode | During a long absence |
| Smart | Automatic adjustment | For everyday use |
Some advanced models support control via Wi-Fi and a mobile application. This allows you to remotely monitor the status of equipment, receive notifications about open doors or temperature changes. To activate this function, you must follow the instructions for pairing the devices.
Secrets of the freshness zone
In some DEXP models, the freshness zone (zero chamber) has a separate air circulation system. Do not fill it tightly with products, otherwise cold air will not be able to wash the packages, and the preservation effect will disappear.
Error diagnostics and fault codes
The refrigerator electronics constantly monitor the condition of sensors and systems. When anomalies are detected, alphanumeric codes or flashing indicators may appear on the display. For example, the code F1 often indicates a malfunction of the temperature sensor in the refrigerator compartment, and F2 in the freezer.
If you see a flashing temperature icon, this may mean that the door has been open too long or is not closed tightly. First of all, check the tightness of the seal and the absence of foreign objects that interfere with closure. Also, the reason may be loading warm products that sharply increased the internal temperature.
- ❗ Sensor error: requires calling a technician to replace the element.
- ❗ Communication failure: try to reboot the refrigerator.
- ❗ Problems with No Frost: check the cleanliness of the air ducts.
⚠️ Attention: If the error code appears again after reboot device, do not attempt to disassemble the refrigerator yourself. This may void the warranty and worsen the breakdown.
It is important to understand that software failures are rare, but they are possible. A complete de-energization for 15–20 minutes often “cures” a frozen controller, resetting temporary errors in the operating logic.
Frequently asked questions (FAQ)
Why does the DEXP refrigerator make a loud sound when operating?
The noise can be caused by several reasons: uneven installation, condenser tubes touching the back wall, or the operation of a fan in the system No Frost. Check the adjustment of the legs and make sure that the appliance is not standing close to the furniture.
How often do you need to defrost a refrigerator with the No Frost system?
The system No Frost automatically removes moisture, so there is no need for regular defrosting. However, once or twice a year it is recommended to carry out general cleaning and washing of the chambers for hygiene.
What to do if ice forms on the back wall?
The formation of a “fur coat” or ice on the back wall may indicate a defrost malfunction, damage to the door seal, or opening the refrigerator too often in hot weather. Check the tightness of the door closure.
Is it possible to install a DEXP refrigerator in an unheated country house?
Most household refrigerators are designed to operate in climate class SN-T or N-ST. Operation at temperatures below +10 degrees can lead to solidification of the oil in the compressor and breakdown, so in winter they cannot be turned on in an unheated room.
