Correct initial setup of a household refrigerator Pozis is a critical stage on which the durability of the compressor and the quality of food storage directly depend. Many owners make the mistake of starting active operation immediately after connecting it to the network, forgetting about the need to stabilize the refrigerant. If you have just brought equipment from the street, especially in winter, it needs time to acclimatize.
Modern models of the Russian brand, be it classic Pozis RK-139 or two-chamber Pozis RK-102, are equipped with reliable thermostats, however, their factory settings may not correspond to your current needs or temperature conditions in room. Thermoregulator is the main control that requires your attention during the first hours of operation. Ignoring the basic rules for setting the temperature regime can lead to rapid spoilage of food or the formation of excessive ice.
In this material we will analyze in detail the process of setting up various modifications, explain how to properly regulate cooling depending on the load of the chambers, and consider the nuances of the operation of electronic and mechanical control systems. A competent approach will allow you to avoid common problems, such as freezing of the rear wall or insufficient cooling of the upper shelves.
Primary preparation and placement of equipment
Before you begin setting temperature conditions, it is necessary to ensure the correct operating conditions. The refrigerator must be placed on a flat, stable surface. Misalignment of the housing can lead to a loose fit of the door, which will cause constant operation of the compressor and freezing of the evaporator. Use a building level to check the horizontal position.
It is important to ensure free air circulation around the condenser, which is usually located on the back wall or sides of the case. The minimum distance from the wall to the back panel should be at least 5-7 centimeters. If the appliance is built-in, you must strictly observe the dimensions of the ventilation gaps indicated in the passport of the specific model Pozis.
⚠️ Attention: If the refrigerator was transported at subzero temperatures, it is prohibited to plug it into the network earlier than 4-6 hours after being brought into a warm room. The oil in the compressor must warm up and drain into the crankcase, otherwise water hammer may occur.
After installing and aligning the legs, wipe the internal chambers with a damp cloth using a weak soda solution. This will remove industrial dust and odors remaining after factory production. Only after the cameras have completely dried can you begin to connect the power.
☑️ Ready to turn on for the first time
Adjusting the mechanical thermostat
Most models Pozis with a drip defrosting system use a mechanical thermostat. It is a rotary knob located inside the refrigerator compartment, often next to the ceiling light or on the top wall. The adjustment scale is usually graduated with numbers from 0 to 7 or from Min to Max.
Position “0” means that the refrigerator is turned off and electricity is not supplied to the compressor. To start working, the knob must be turned to the position corresponding to the average value, usually numbers 3 or 4. Thermostat in this position it will maintain a temperature of about +4..+5°C, which is optimal for storing most products.
It is not recommended to immediately set maximum cooling (numbers 6-7). This will force the compressor to work without stopping, which will lead to heavy accumulation of ice on the rear wall and possible freezing of food. The adjustment should be carried out smoothly, taking breaks between switchings of at least 30-40 minutes to stabilize the temperature background.
If you notice that the food in the refrigerator compartment begins to freeze, and a thick ice crust forms on the back wall, you need to reduce the value on the thermostat. Conversely, if (the compressor) works rarely and the temperature inside rises, the knob should be turned towards higher numbers.
Setting the electronic control and display
More modern models, such as Pozis RK-168 or series Smartcan be equipped with an electronic control unit with digital display. In such units, settings are made by pressing buttons on the front panel of the door or inside the chamber. There are no abstract numbers here, you set the exact temperature in degrees Celsius.
To change the settings, you usually need to press and hold the setting button (often indicated as Set or a thermometer symbol) for 3-5 seconds until the numbers on the screen begin to flash. After this, use the “+” and “-” buttons to set the desired value. Standard recommendation for the refrigerator compartment - +3°C or +4°C.
| Operating mode | Temperature (HC) | Temperature (MK) | Description |
|---|---|---|---|
| Standard | +4°C | -18°C | Daily food storage |
| Eco / Economy | +6°C | -12°C | With small loads to save money |
| Super cooling | +2°C | -18°C | For quick cooling of drinks |
| Super Freeze | +4°C | -24°C | For freezing fresh food |
Electronics allows you to more accurately control the operation of the unit, but it is sensitive to power surges. If the display goes dark or shows chaotic characters, try unplugging the device for 10-15 minutes to reboot the controller.
Super Freeze function
One of the key functions that requires correct settings is the mode Super Freeze. It is designed to quickly freeze large quantities of fresh food placed in the freezer. When this mode is activated, the compressor operates continuously, ignoring the thermostat readings.
In models with mechanical control, a separate button (often yellow) or an additional position on the regulator is provided to enable this function. In electronics, the mode is activated through the menu.
⚠️ Attention: Do not leave the “Super Freeze” mode on for longer than 48-72 hours. Prolonged operation at maximum power without interruption reduces the life of the compressor and may trigger the thermal protection relay.
After fresh food is completely frozen (usually after 24 hours), the function must be forcibly turned off. In some models with intelligent control, the timer turns off this mode automatically, but you shouldn’t rely on this - it’s better to check the indicator yourself.
What happens inside during Super Freeze?
In this mode, the fan (if there is No Frost) runs at maximum speed, and the compressor does not turn off even when the target temperature is reached. The refrigerant circulates with maximum intensity, lowering the temperature in the freezer to -24..-26°C.
Setting the freshness zone and zero chamber
Many refrigerators Pozis are equipped with a special freshness zone (zero chamber), where the temperature is maintained at about 0°C and certain humidity. This is an ideal place for storing meat, fish, dairy products and vegetables, which quickly spoil in a regular compartment.
In some models, this zone is adjusted automatically, in others there is a separate damper control or a switch for the “Meat/Fish” and “Vegetables/Fruits” modes. For meat and fish, the humidity should be lower so that the surface of the products does not become airy, and for vegetables it should be higher so that they do not wilt.
If you find that food is freezing in the freshness zone, check whether the load is blocking the outlet of cold air. It is also worth (slightly) increasing the temperature in the main compartment of the refrigerator, since the freshness zone directly depends on the general temperature background of the chamber.
Common errors and their elimination
Even with correct settings, users may encounter problems that are often mistaken for a malfunction. For example, the formation of condensation on external walls or inside chambers. In most cases, this indicates a violation of the temperature regime or operating rules, and not a breakdown.
A common mistake is to install the refrigerator next to (heat sources), such as radiators or gas stoves. In this case, even the maximum setting of the thermostat will not help to achieve the desired temperature, and the compressor will work for wear.
- ❄️ Increasing "fur coat": Check the tightness of the door seal and make sure that you do not put hot products inside.
- 🔊 Extraneous noise: Make sure that the refrigerator is level and does not touch furniture; check if the shelves are vibrating.
- 💧 Water on the floor: Check the drainage hole on the back wall - it should not be clogged with crumbs or ice.
If you have followed all the recommendations for setting up, but the refrigerator continues to work incorrectly (does not turn off, does not freeze, makes strange sounds), it may require diagnostics by a specialist. Independent repair of complex components without the appropriate skills is prohibited.
Frequently asked questions (FAQ)
What temperature should be set in the Pozis refrigerator in the summer?
In the summer, when the ambient temperature (ambient temperature) is high, it is recommended to set the thermostat to a value slightly above average (for example, 2-3 instead of 4-5 for mechanics, or +5°C for electronics). This will compensate for heat inflows and prevent overheating of the compressor, although the products will be stored at a slightly higher, but safe temperature.
Why is the red light on after setting?
The red indicator usually signals an increased temperature in the chamber. This is normal immediately after switching on or loading a large amount of warm food. The light should go out after a few hours. If it is constantly on, check that the door is tightly closed and the position of the thermostat.
Can a Pozis refrigerator be used as a freezer?
No, refrigerators Pozis are not designed to operate in freezer-only mode. Disabling the refrigerator compartment (if such a function exists) is only possible temporarily. Constant operation of only the freezer will lead to an incorrect defrost cycle and failure of the system.
How often do you need to defrost a refrigerator with a drip system?
Models with a drip system (“Crying wall”) require manual defrosting approximately 2-4 times a year, depending on the humidity in the room and the frequency of opening the door. A complete shutdown for defrosting is necessary when the layer of ice on the back wall becomes too thick.
