Buying new household appliances is always accompanied by excitement, especially when it comes to large equipment such as refrigerator. The brand DEXP offers affordable and functional models, however, the correct operation of the device directly depends on the correctness of its initial activation. Many users make the mistake of starting to operate the unit immediately after unpacking, which can lead to serious damage to the compressor.
The process of turning on the refrigerator DEXPdoes not come down to simply pressing a button. There is a critical time interval that must be maintained before applying voltage. Ignoring this stage often causes the failure of an expensive compressorcompressor, since the oil that got into the circuit during transportation has not yet had time to drain into the crankcase.
In this article we will analyze in detail all the stages: from correct installation to fine-tuning temperature conditions through the control panel. You will learn how to activate the mode Super Freeze, what to do if the device emits beeps, and how to avoid typical mistakes that inexperienced users make when starting up for the first time.
Preparation for the first launch and waiting time
The most important stage is the period of adaptation of the equipment after delivery. If the refrigerator DEXP was transported in a horizontal position or with a strong tilt, compressor oil could leak into the cooling system. An instant start in this condition will lead to the engine running dry or water hammer, which is fatal for the unit.
The time that must be waited before plugging in depends on the transportation conditions and the ambient temperature. During the cold season, this period increases, as thickened oil returns to the reservoir more slowly. In summer, the process takes less time, but it absolutely cannot be neglected.
⚠️ Attention: If the refrigerator was brought in from the cold, let it stand in a warm room for at least 4-6 hours before turning it on. A sudden temperature change can cause condensation on electronic components, which will lead to a short circuit.
The optimal holding time for models DEXP is:
- 🕒 For vertical transportation - from 2 to 4 hours.
- 🚚 For horizontal transportation - at least 8-12 hours.
- ❄️ In winter (after the street) - up to 24 hours for complete warming up.
After the specified time has expired, make sure that the device is installed level. Use a building level to check for levelness. Incorrect installation will cause vibration, noise and incorrect closing doorswhich will break the tightness of the circuit.
Connecting to the power grid and checking the voltage
Refrigerators DEXP, like any modern equipment that is sensitive to voltage changes in the network. Before inserting the plug into the outlet, it is recommended to check the condition of the wiring. The use of extension cords or tees is undesirable, since the connections may heat up and create additional resistance.
For safe operation, it is best to use a separate one socket with grounding. If power surges often occur in your area, it is advisable to purchase a voltage stabilizer. This will extend the life of the electronic control module and compressor.
Make sure the plug fits tightly into the socket. Backlash can lead to sparking and melting of contacts. After connecting, the device may not make any sounds immediately - this is normal for models with electronic control, which require time for self-diagnosis.
⚠️ Attention: Do not plug in the refrigerator if the power cord or plug is visibly damaged. This may result in a fire or electric shock.
Setting the temperature mode and control panel
After power is applied, the refrigerator control panel DEXP is activated. Depending on the model, this may be a touch screen or mechanical controls inside the camera. The electronics will set average values by default, but for proper freezing of products they need to be adjusted.
The optimal temperature in the main chamber should be from +2 to +4 degrees Celsius. For long-term storage in the freezer compartment, we recommend -18°C. If you plan to freeze a large amount of fresh food, use the function Super Freeze (Super Freeze).
To configure, follow these steps:
- Press the button
TemporModeon the control panel. - Use arrows or taps to select the desired value.
- Confirm your selection if the model requires confirmation, or just wait a few seconds.
Some models DEXP equipped with a mode Eco, which saves energy by slightly increasing the temperature in the chambers. This mode is convenient when you are leaving for a few days and do not plan to open the refrigerator.
☑️ Setting the temperature
Indication and sound signals at start
Modern refrigerators DEXP are equipped with a self-diagnosis system that reports its status through light indicators and sound signals. When you turn it on for the first time, you may hear a single beep - this means that the control system has successfully passed the test.
If you hear repeated beeps, this may indicate that the door is not closed tightly or the temperature inside the chambers has not yet reached the set values. In the first hours of operation, thermostat will actively cool the volume, so the signals may be temporary.
Decoding of the main indicators:
- 🔴 The red temperature indicator is on - the temperature in the chamber is above normal.
- 🔵 Blue indicator - super freezing mode is active.
- 🔔 Flashing bell icon - the door is open or the sensor is faulty.
It is important to distinguish between the normal noise of the compressor and alarm signals. The compressor can operate cyclically: turn on, cool and turn off. In models with No Frost you will also hear the sound of the fan and periodic crackling noise when the evaporator defrosts.
What do the error codes on the display mean?
If codes like E1, E2 or F3 appear on the screen, this indicates a specific malfunction of the temperature sensor or defrost system. Write down the code and contact the service center without trying to disassemble the refrigerator yourself.
Table of recommended storage temperatures
Correctly setting storage zones allows food to stay fresh longer. In refrigerators DEXP with a system Multi Air Flow the temperature is distributed evenly, but the placement of products on different shelves matters.
| Storage area | Recommended temperature | What to store | Shelf life (approximate) |
|---|---|---|---|
| Top shelf | +4...+5°C | Ready food, drinks | 2-3 days |
| Middle shelf | +2...+4°C | Dairy products, sausages | 3-5 days |
| Bottom shelf | 0...+2°C | Raw meat, fish | 1-2 days |
| Door shelves | +5...+7°C | Sauces, eggs, drinks | Depends on the product |
| Freezer | -18°C and below | Frozen foods | Up to 12 months |
Do not overload shelves immediately after switching on. Allow the refrigerator DEXP to return to operating mode in an empty state or with a minimum amount of food. This will help to quickly stabilize microclimate inside the chambers.
Frequent problems during first startup and their solutions
Even if all instructions are followed, users may encounter nuances in the operation of the equipment. For example, the side walls of the refrigerator may become noticeably hot. This is not a defect, but a feature of the heat removal system, especially in models where the condenser is built into the side panels.
If the refrigerator DEXP does not turn off for a long time on the first day, this is normal. It takes time to cool the large internal volume and walls. The alarm should be sounded if the compressor operates without stopping for more than 24-30 hours in a row.
⚠️ Attention: Technical characteristics and operating algorithms may vary depending on the specific series and year of manufacture of the model. Always check the official instructions included in the packaging of your device.
List of common situations:
- 💧 Water appears on the floor - check the drainage hole in the main chamber, it should not be clogged.
- 🧊 Ice formation on the back wall - perhaps the door does not fit tightly or the temperature setting is set too low.
- 🔊 Humming or gurgling - the sound of flowing refrigerant is the norm for a working unit.
In case of difficulties malfunctions not related to user settings, it is recommended to contact an authorized service center. Self-repair may deprive you of your warranty guarantees.
Is it possible to turn on the DEXP refrigerator immediately after delivery?
Strongly not recommended. Even if the transportation was vertical, you must wait at least 2-4 hours for the oil to drain into the compressor. When transporting horizontally, the waiting time increases to 12 hours.
Why does the DEXP refrigerator make clicks during operation?
The thermal relay can make clicks when turning the compressor on and off, as well as the plastic of the case during thermal expansion. If clicks are not accompanied by other signs of failure, this is normal.
How to activate the super freezing mode?
Press the button with the image of a snowflake or the inscription Super Freeze on the control panel. The indicator will light up and the compressor will run continuously for fast cooling. Do not forget to turn off this mode manually after 24 hours if it does not turn off automatically.
What to do if the red temperature indicator is on?
In the first hours after switching on, this is normal. If the indicator is on for more than a day, check the tightness of the door closure, the presence of products blocking the airflow, and the correctness of the thermostat settings.
