Purchasing new refrigeration equipment is always an event that marks the beginning of a comfortable life, but the correctness initial start-up directly affects the durability of the compressor and the quality of cooling products. Refrigerators Pozis have proven themselves to be reliable equipment, but even the most advanced unit requires compliance with certain rules when first connecting to the electrical network. Ignoring simple but critical preparation steps can lead to a reduction in the service life of the motor or incorrect operation of the defrost system.
Before proceeding to directly plugging the plug into the outlet, you must make sure that all preparatory conditions dictated by the physics of the refrigerant are met. In this article, we will look in detail at how to prepare equipment for operation, how long you need to wait after delivery, and how to adjust the temperature for maximum efficiency.
Particular attention should be paid to transportation conditions, since the position of the refrigerator when moving determines the need for a pause before starting. If you delivered the device in a vertical position, the waiting time will be minimal, while horizontal transportation requires a much longer wait for the oil to drain into the compressor crankcase.
Preparation of the installation site and unpacking
The first step before switching on is the proper installation of the unit in the intended place. The refrigerator Pozis must be located on a flat, stable surface, away from direct sunlight and heating devices. Distance to the wall must be at least 5-7 centimeters to ensure free air circulation around the condenser, which is critical for effective heat transfer.
After installation, it is necessary to remove all transport elements, which inexperienced users often forget to remove. We are talking about plastic clips, tape, foam pads and, most importantly, internal fasteners that hold shelves and drawers in place during transport. Packing materials left inside can block airflow and lead to local overheating.
⚠️ Attention: Never turn on the refrigerator if the protective film has been removed from the heat exchanger on the rear wall (if it is provided for in the design), as this will interfere with heat removal.
Check the integrity of the door seals - they must fit tightly to the body around the entire perimeter. If you notice creases or a loose fit immediately after unpacking, try heating the deformed area with a hairdryer at low temperature or leaving the door closed for several hours - the rubber should straighten out.
☑️ Preparing for the first launch
Temperature adaptation and time expectations
The key point in the question of how to properly turn on the refrigerator Pozisis to observe the time interval between delivery and power supply. This rule is due to the need to return compressor oil to the engine crankcase. During transportation, especially in a horizontal position, the oil mixes with the refrigerant and spreads through the pipeline system.
If you start the compressor immediately while the oil is in the circuit, water hammer or dry operation may occur, which will lead to rapid wear of the rubbing parts or jamming of the piston group. The holding time depends on the method of transportation:
- 🚛 Vertical transportation: if the refrigerator was transported standing, it is enough to let it stand for 2-3 hours to stabilize the temperature and drain the remaining oil.
- 🛌 Horizontal transportation: when lying down, the waiting time increases to 8-12 hours, and in some cases (in winter) it is recommended to stand the unit up to 24 hours.
- ❄️ Winter delivery: If the equipment came into the room from frost, do not turn it on for at least 4-5 hours until the insides warm up to room temperature to avoid damage to the wire insulation.
⚠️ Attention: Failure to comply with the soaking time frame is the most common cause of compressor failure in the first month of operation and may be grounds for refusal of warranty service.
It is also important to take into account the temperature conditions in the room. The optimum temperature for refrigerators Pozis is considered to be from +16 to +32 degrees Celsius. Installing the unit in an unheated room (for example, on a balcony) requires clarification in the instructions whether a particular model supports operation in such conditions (climate class).
Why should the oil drain?
Compressor oil has a high viscosity and when the housing is tilted, it flows into the evaporator and condenser. If you start the engine, the oil in the tubes will create resistance to the movement of the refrigerant, and the compressor itself will remain without lubrication, which will cause metal-to-metal friction.
First connection to the electrical network
After you have waited the required time and prepared the place, you can proceed to the electrical connection. The socket into which the refrigerator will be plugged in Pozismust be grounded and meet power requirements (usually up to 2 kW). It is highly not recommended to use extension cords or tees, as they can cause poor contact, heating and even fire.
When connecting, pay attention to the power cord - it should be straightened and not touch hot parts of the refrigerator, such as the condenser grille on the back wall. Modern models often provide a system of protection against power surges, but additional installation of a stabilizer or voltage control relay in the panel will never be an unnecessary safety measure.
At the moment of switching on, you can hear the characteristic sound of the compressor starting or the gurgling of refrigerant - these are normal operating sounds. However, if you hear a loud metallic clanging or buzzing sound that lasts more than 10-15 seconds without switching to quiet mode, the device should be turned off immediately and contact service.
Setting the thermostat and operating modes
Immediately after turning on, the refrigerator will begin to gain temperature, but for the system to operate correctly, you must set the settings correctly. Depending on the model Pozis (mechanical or electronic control panel), the setup process may differ. Mechanical models use a rotary regulator with numbers from 1 to 5 or 7.
It is important to understand that the numbers on the mechanical regulator do not indicate degrees, but cooling intensity. The higher the number, the colder it will be in the chamber. For the initial start-up, it is recommended to set the regulator to the middle position (usually 3 or 4) so as not to overload the compressor during the first hours of operation.
In models with electronic control, the setting is made via the display. Here you can select a specific temperature for the refrigerator and freezer compartments separately. Standard recommended values:
| Chamber | Recommended temperature | Operating mode |
|---|---|---|
| Refrigerator compartment | +2...+4 °C | Standard / Eco |
| Freezer camera | -18 °C and below | Frozen / Super-freeze |
| Zero zone (BioFresh) | 0 °C | For meat and fish |
| Vacation mode | +10...+15 °C | Economical |
You should not immediately load the cameras with products after turning them on. Let the unit run idle for 2-4 hours so that it reaches operating mode and stabilizes the temperature in all volumes.
Loading products and entering mode
The refrigerator should be fully loaded with food only after it has been idle for several hours. Suddenly introducing a large volume of warm food will cause the compressor to work hard for a long time trying to compensate for the heat. It is better to load the chambers gradually, in small portions.
When placing products, follow the rules of product proximity and air circulation. Do not place food close to the back wall of the refrigerator, especially if the evaporator is located there - this may lead to freezing of the packaging or spoilage of the food. There should be a gap of 1-2 centimeters between the products and the walls.
The rule for the freezer is: the tighter the packing, the better, but only after the initial freezing. It is not recommended to immediately fill an empty freezer with warm food - it is better to freeze bags of water in advance or use the Super Freeze (Super Freeze) mode, which forcibly turns on the compressor at maximum power.
⚠️ Attention: Do not store open products with a strong odor (fish, spices, smoked meats) in the refrigerator compartment without sealed packaging, since the smell can be absorbed into the plastic parts of the case and seals, which will then be difficult to get rid of.
Typical errors when starting up for the first time
Even careful study of the instructions does not always guarantee the absence of errors, especially if the user is in a hurry. One of the most common problems is trying to turn on the refrigerator immediately after bringing it into the house in winter. Condensation formed on internal electronic components due to temperature changes can cause a short circuit.
Another common mistake is installing the refrigerator close to the wall or in a niche without gaps. In this case, heat exchange the refrigerator stops turning off, trying to reach the set temperature, which leads to excessive energy consumption and overheating of the motor.
Also, users often ignore the tilt level. If the refrigerator is not level, the door may not close on its own or, conversely, may slam shut too abruptly. In addition, an incorrect tilt can disrupt the flow of condensate into the evaporator, which will lead to the appearance of puddles under the drawers.
Frequently asked questions (FAQ)
Is it possible to turn on the Pozis refrigerator immediately after defrosting?
Yes, if defrosting was carried out as planned and without moving it itself unit. In this case, it is enough to wipe the chambers dry and turn on the device 15-20 minutes after the end of defrosting to dry the moisture.
Why does the refrigerator hum after the first turn on?
In the first hours of operation, the hum may be more pronounced as the system enters operating mode. If the hum is not accompanied by vibration of the case and gradually subsides, this is normal. If the sound increases, check whether the shipping bolts have been removed and whether the refrigerator is level.
Does it need to be washed before turning on the new refrigerator?
Absolutely. There may be a technical smell of plastic and grease inside. Wipe all surfaces with warm water with baking soda or a mild detergent, then wipe dry and ventilate the chambers open for several hours.
What to do if the refrigerator does not cool after turning on?
Wait 4-6 hours. During the first hours of operation, the refrigerator may not show visible cooling results, especially if the room is hot or it was loaded with food at once. If after 6 hours the chamber is warm and the compressor is working, contact service.
