Turning on refrigeration equipment after purchase or long-term transportation is a responsible process, requiring compliance with certain technical nuances. The brand Pozis has established itself as a manufacturer of reliable equipment, however, even the highest quality models require the right approach to the first launch. Errors at this stage can lead to a reduction in the service life of the compressor or a violation of the tightness of the circuit.
Modern models are equipped with effective cooling systems, but their operation directly depends on how you prepared the unit for operation. It is important not just to plug the cord into the outlet, but to carry out a set of preparatory work. This applies to stabilizing the refrigerant and checking the electrical network.
In this material we will analyze in detail the algorithm of actions that will help you safely activate your device. You will learn why standing time plays a critical role and how to adjust the temperature regime for ideal food preservation.
Preparation after transportation: waiting time
The first thing that the owner of a new equipment faces is a matter of time. When transporting a refrigerator, especially in a lying position, oil from the compressor inevitably flows into the evaporator and condenser pipe system. If you start the unit right away, the compressor will run dry, which will lead to rapid wear or jamming.
The time required for the oil to drain back into the crankcase depends on the ambient temperature and the position of the equipment during transportation. In winter, when equipment is delivered at sub-zero temperatures, the adaptation process takes longer. The oil becomes thicker, and it takes more hours for it to take its normal place.
⚠️ Attention: If the refrigerator was brought in from the cold, it is strictly forbidden to plug it into the network immediately. Sudden temperature changes can cause condensation on electrical contacts, resulting in a short circuit. Allow the device to warm up to room temperature for at least 3-4 hours.
For horizontal transportation, manufacturers Pozis recommend a pause of at least 8-10 hours, or better yet, a full day. Vertical transportation is less critical, but in this case the minimum rest is 2–4 hours. Take your time: it is better to spend extra time waiting than to change the compressor.
Remember that the refrigerant must also stabilize in the system. A sudden start can cause water hammer, which is dangerous for the compressor valves.
Selecting an installation location and electrical requirements
Before connecting the power cord, make sure that the refrigerator is installed correctly. The body must be strictly horizontal. This is necessary to ensure that the doors close automatically under the influence of gravity and ensure proper circulation of refrigerant. The legs are adjusted by rotating the support screws.
Pay special attention to the distance to walls and furniture. The rear grille of the condenser should be well washed with air. The minimum gap from the wall is 5–10 cm, and it is advisable to leave space on the sides for ventilation. Overheating of the compressor due to poor ventilation is a common cause of breakdowns.
The electrical network must correspond to the parameters specified in the device passport. Usually these are standard 220–230 V with frequency 50 Hz. It is highly not recommended to use an extension cord or connect the refrigerator to the same outlet with powerful consumers (washing machine, microwave).
The ideal solution would be to connect through a surge protector or voltage stabilizer, especially if there are surges in your network. This will protect the electronics and the compressor motor.
Initial startup and checking the operation of the compressor
After the device has settled and taken its place, you can proceed to the initial startup. Make sure that the doors are tightly closed and that there are no foreign objects or packaging materials (tape, foam, films) inside.
Insert the plug into the outlet. At this moment you may hear a slight click - this is normal, the start relay is activated. After a few seconds the compressor should start working. The characteristic hum of the motor indicates the start of the refrigeration cycle.
☑️ Check before starting
Modern models Pozis can be equipped with a No Frost or drip defrosting system. In the first minutes of operation, you may not feel the cold immediately, since the system takes time to circulate freon. However, after 10–15 minutes, the walls of the chamber should begin to cool.
Listen to the sounds of the unit operating. Quiet humming and periodic gurgling of the refrigerant in the tubes is allowed. A loud knock, clanging or high-pitched whistle indicates a malfunction or incorrect installation.
Setting the temperature mode
After successful startup, you need to adjust the temperature. Depending on the model Pozis, the control can be mechanical (thermostat with numbers) or electronic (display and buttons). The mechanical regulator is usually located inside the chamber or on the top panel.
The numbers on the mechanical regulator do not mean degrees Celsius, they indicate the cooling intensity. Typically the scale goes from 1 to 5 or from 1 to 7. Unit is the minimum cooling (warmer), and the maximum number is its cooling (colder).
For initial start-up, it is recommended to set the regulator to the middle position (for example, on 3 or 4). This will allow the system to return to operating mode without overload. After a few hours, when the temperature stabilizes, you can adjust the settings to suit your needs.
| Knob position | Intensity | Approximate temperature | Recommendation |
|---|---|---|---|
| 1 (Min) | Minimum | +8...+10 °C | For short-term storage |
| 3 (Avg.) | Optimal | +3...+5 °C | Daily use |
| 5 (Max) | Maximum | 0...+2 °C | For quick freezing |
| 0 | Off | - | The compressor does not work |
If your model has a separate freezer with a regulator Super Freeze (super freezing), do not keep it on all the time. This mode is designed for quick freezing of a large volume of food and heavily loads the compressor.
Loading food and entering the mode
After turning on the refrigerator, do not rush to fill it with food to capacity. An empty refrigerator requires 2 to 4 hours to cool the internal volume to the specified parameters. If you load warm food at once, the compressor will work hard trying to compensate for the heat.
It is recommended to wait until the first compressor shutdown (the operating cycle is completed) before starting active loading. It is better to place the first portions of food in small batches.
Is it possible to turn on an empty refrigerator?
Yes, you can and should turn on an empty refrigerator to check its operation. However, you cannot store it empty and turned off with the doors closed - mold and an unpleasant odor may appear.
Distribute the products evenly, do not block the air circulation holes (especially in models No Frost). This will ensure the same temperature in all corners of the chamber.
Diagnosis of possible problems during startup
Sometimes, after switching on, situations may arise that require intervention. For example, the refrigerator hums, but does not cool, or, conversely, is too loud. It is important to be able to distinguish normal operation from a malfunction.
If the compressor turns on, runs for a few seconds and turns off with a click, and then tries to turn on again, this may indicate a problem with the start relay or the engine itself. In this case, operation should be discontinued.
⚠️ Attention: If you smell burning conductor or see sparking in the outlet or rear panel area, immediately unplug the appliance. Do not try to disassemble the electrical part yourself unless you have the appropriate qualifications.
It is also worth checking the door seals. If they do not fit tightly, the cold will escape and the compressor will work continuously, which will lead to the formation of a “coat” of ice and excessive energy consumption.
Frequently asked questions (FAQ)
How long can the Pozis refrigerator be turned on after delivery?
The minimum waiting time is 2-4 hours for vertical transportation. If the refrigerator was lying during transportation or was brought in from the cold, the waiting time increases to 8–12 hours (and in winter it is better up to 24 hours) for the oil to drain and equalize the temperature.
Why does the refrigerator hum loudly after the first turn on?
The new compressor may work noisier in the first hours due to the grinding in of parts. Noise can also occur if the refrigerator is uneven and vibrates. Check the adjustment of the legs and the clearances to the walls.
Can the Pozis refrigerator be placed on a balcony?
Operation on an unglazed balcony is prohibited due to precipitation and extreme temperatures. On a glazed balcony, use is only possible if the temperature range specified in the instructions is observed (usually from +10 to +32 °C).
What to do if the refrigerator does not freeze after turning on?
Wait 4-6 hours. If during this time the temperature has not decreased and the compressor is running (or does not start at all), check the position of the thermostat. If the settings are correct, you will need to call a technician to check the presence of freon or the serviceability of the compressor.
Do you need to defrost the Pozis refrigerator before using it for the first time?
No, new refrigerators do not require defrosting before the first use. They are supplied dry and clean. It is enough just to wipe the internal shelves with a damp cloth and a mild detergent to remove dust.
