Buying new household appliances is always a joyful event, but it is often overshadowed by the difficulties of initial installation, especially when it comes to large-sized equipment. Owners of equipment from a Ukrainian brand often wonder how exactly the process should go first start-up and whether there are specific nuances characteristic of this particular brand. Incorrect actions in the first hours of operation can lead to serious damage to the compressor or disruption of refrigerant circulation.
Many users make the mistake of believing that they just need to insert the plug into the socket and the unit will immediately begin to operate normally. In fact, the technique requires an adaptation period, especially after transportation, when internal oil may have shifted into the tube system. Ignoring the rules for initial startup often becomes the reason that the device fails long before the end of the warranty period.
In this material we will analyze in detail all the stages of preparation for operation, starting from unpacking and ending with setting the optimal temperature regime. You will learn why you should not rush to start up, how to check the serviceability of the main components and what signals indicate that the unit is working correctly. A competent approach to installation will ensure a long service life of your Nord and safety of products.
Transportation rules and settling time
The most critical moment after delivering the equipment to the apartment is the time interval before the first connection to the power grid. The fact is that the compressor contains oil, which during tilting or shaking during transportation could get into the cooling circuit. If you start the engine right away, it will run dry, which will lead to rapid wear of the piston group or jamming.
The time that needs to be waited directly depends on the position in which the unit was transported. If the device was standing upright and was not subjected to strong shaking, it is enough to let it stand alone for about 2-3 hours. If transportation was carried out in a supine position, this interval should be increased to 8–12 hours, and in the winter - up to a day, so that the oil completely drains back into the compressor crankcase.
⚠️ Attention: It is strictly forbidden to plug in the device immediately after bringing it into a warm room from the cold. Sudden temperature changes will cause condensation on electronic components, which may result in a short circuit. Allow the equipment to warm up to room temperature while switched off for at least 4 hours.
It is also important to consider the ambient temperature. If you brought the refrigerator from the street in the cold season, condensation can form not only outside, but also inside the insulating layers. Thermoregulator and other sensitive elements should warm up naturally, without the use of external heating devices.
Initial inspection and preparation for launch
Before Before starting active use, it is necessary to conduct a thorough visual inspection and preparation of the internal space. Manufacturers often use shipping tape, plastic clamps, and foam inserts to protect shelves and doors during moving. All these elements must be removed, as they block the normal operation of the mechanisms.
The next step is hygienic treatment. Even if the device is new, the smell of factory grease, plastic, or dust accumulated in a warehouse may be present inside. To clean the inner chambers, use a weak solution of baking soda or a mild detergent. After wet cleaning, be sure to wipe all surfaces with a dry cloth and leave the doors open for 30-60 minutes for ventilation.
- 🧼 Thoroughly wash all removable shelves, vegetable drawers and containers on the door with warm water and soap.
- 🔌 Check the integrity of the power cord and make sure that the plug is not has mechanical damage.
- 🌬️ Make sure that the ventilation holes on the back wall are not covered with packaging materials.
- 📏 Check the stability of the unit: it should not wobble, if necessary, tighten the adjustable supports.
Particular attention should be paid to the system No Frostif your model is equipped with it. Make sure the air ducts are not blocked by improperly installed shelves. Improper air circulation can lead to the formation of ice even in a working device.
☑️ Preparation for first use
Step-by-step instructions: how to turn on the refrigerator
The process of activating the device is quite simple, but requires a sequence of actions for the correct operation of the electronics and mechanics. First, make sure that the outlet to which the equipment will be connected is working and grounded. The use of extension cords or tees is not recommended, since the compressor creates a high starting load on the network when starting.
After connecting to the network, the device may emit a characteristic click or a quiet hum - this is normal, the control system begins to work. On some modern models with an electronic display, immediately after switching on, indicators will light up, signaling the transition to operating mode. If the model is mechanical, simply turn the thermostat knob to the position recommended by the instructions (usually this is the average value).
Sequence of actions:1. Make sure there is voltage in the network (220V).
2. Insert the plug into the socket as far as it will go.
3. Turn the thermostat knob clockwise.
4. Wait 10-15 minutes before starting the compressor for the first time.
This is due to the operation of the protective relay and the algorithms of the electronic control unit, which check the system before starting. Do not panic if in the first minutes of silence you do not hear the characteristic hum of the motor.
Why does the refrigerator hum immediately after turning on?
A humming or gurgling sound in the first minutes of operation is a normal physical process. The refrigerant begins to circulate through the system, passing through the expansion valve, which may be accompanied by the sounds of flowing liquid. If the noise is not accompanied by vibration of the case or knocking, there is no need to worry.
Setting the temperature mode and functions
After the device is working, you need to set the temperature correctly. For models with mechanical control, the thermostat knob usually has a scale from 1 to 7 (or from Min to Max). The optimal value for everyday work is position 3 or 4, which corresponds to a temperature of about +4..+5°C in the main chamber.
If you have a model with electronic control, the setting is made through the panel on the door. Here you can set the exact values for the refrigerator and freezer compartments separately. It is recommended to set the value in the freezer to -18°C, and in the refrigerator to +4°C. The function Super Freeze (super freezing) is useful when loading a large volume of fresh food, but should not work constantly, as this increases energy consumption.
| Knob position | Temperature mode | Recommended use |
|---|---|---|
| 1 (Min) | +8..+10°C | Storage of prepared meals, drinks |
| 3-4 (Average) | +3..+5°C | Daily food storage |
| 6-7 (Max) | 0..+2°C | Quick cooling, meat storage |
| 0 (Off) | — | Mode defrosting or turning off |
Do not immediately set the maximum cooling power. A sudden drop in temperature can cause food to freeze on shelves or glass elements to break due to thermal shock. It is better to set the medium mode and, if necessary, increase the cooling later.
Diagnostics: how to understand that the refrigerator is working
You can understand that the unit is functioning properly by several signs. First of all, this is a cyclical operation: the compressor must turn on, work for a certain time (gain cold), and then turn off. The ratio of work and rest time in normal mode is approximately 1:2 or 1:3, that is, for 10 minutes of work there are 20-30 minutes of rest.
The cooling efficiency can be assessed no earlier than 5-6 hours after switching on. By this time, the empty chambers should cool down to the specified parameters. If you put your hand on the side walls of the operating device, they may be warm or even hot - this is normal, since condenser tubes are located here, releasing heat to the environment.
- ❄️ After a few hours, a thin layer of frost should appear on the inner walls of the freezer (for a drip system) or no frost at all (for No Frost).
- 🔇 Turning off the compressor should be accompanied by silence; there may be a slight cracking of the plastic or gurgling.
- 💡 The operation indicator (light inside or on the panel) should light up only when the door is opened or light constantly, signaling power.
If the compressor operates continuously more than 2 hours without turning off, and the temperature inside does not drop, this may indicate a freon leak or a malfunction of the thermostat. In this case, specialist intervention is required.
⚠️ Attention: If you hear a loud metallic knocking, clanging or whistling sound when the compressor is operating, immediately unplug the device. Continued operation may lead to permanent engine failure. Such sounds are not the norm for working Nord equipment.
Typical errors during first startup
One of the most common errors is loading products immediately after switching on. Many users strive to fill all the shelves, forgetting that the empty volume needs time to cool. If you place warm foods or a large volume of food in a chamber that has not cooled down, the compressor will work hard trying to compensate for the heat, which can lead to overheating.
Another common mistake is installing the device close to the wall or in a niche without gaps. For effective heat exchange, the back wall and sides require free access of air. The minimum distance to the wall should be at least 5–7 cm, and on the sides - 3–5 cm. Violation of this rule leads to overheating of the condenser and reduced efficiency.
Also, users often ignore the installation level. If the refrigerator is skewed, the door may not close tightly on its own, which leads to the constant entry of warm air and the formation of a “fur coat” on the evaporator. Use a building level to check the horizontal position.
What to do if an unpleasant odor appears after turning it on?
If after the first turn on you smell burnt plastic, this may be normal in the first 15–20 minutes (factory lubricants burn out on the heating elements). However, if the smell is strong and does not go away after an hour, or there is a smell of burnt wiring, unplug the appliance immediately. Also, the smell can come from products that were stored in the warehouse, so thorough washing of the chambers before starting is necessary.
Is it possible to turn on the Nord refrigerator through an extension cord?
Manufacturers do not recommend using extension cords, especially cheap ones with a thin wire. The compressor draws high starting current, which can cause the extension cord contacts to heat up and melt, creating a fire risk. If the outlet is far away, it is better to use a high-quality surge protector with grounding and a rated current of at least 10A.
How long does it take the refrigerator to reach temperature for the first time?
Complete cooling of the internal volume to the specified parameters for the first time takes from 6 to 12 hours. This depends on the ambient temperature in the room, the volume of the chambers and the model of the refrigerator. It is better to load products for long-term storage after the device has completed at least one full cycle of on and off.
Why does the Nord refrigerator turn on and immediately turn off?
If the unit starts, makes several clicks and stalls, the thermal protection relay may be triggered due to problems with the compressor or starting capacitor. The cause may also be low voltage in the network. If this happens several times, call a specialist - repairing the electrical part yourself is dangerous.
