Modern refrigeration units of the brand Pozis are distinguished by high functionality and reliability, but their effective operation requires competent initial setup. Many users make the mistake of believing that it is enough to simply plug in the device and load food, but ignoring the operating instructions can lead to rapid damage to the equipment or poor quality food storage. The correct configuration of operating modes allows you to extend the life of the compressor and ensure an optimal microclimate inside the chambers.
The setup process begins long before you touch the control panel or temperature regulators. A critical step is to properly prepare the unit for the first start after transportation. If you have just brought a refrigerator from the store, it needs to stand in an upright position for a period of time, which directly depends on the air temperature outside and the duration of transportation. Thermoregulation and the lubricants in the compressor must take their regular places before the system is started under load.
In this material we will detail We will analyze all the stages of setting up various models of refrigerators Pozis, from mechanical thermostats to electronic control systems with a display. You'll learn how to set the ideal temperature for different compartments, what the indicators on the panel mean, and how to activate the fast freeze modes. Understanding these processes will allow you to avoid common mistakes and enjoy fresh food for a long time.
Primary preparation and installation of the refrigerator
Before you start setting the temperature conditions, you need to ensure the correct placement conditions for the refrigerator. The unit must stand on a flat, hard surface to eliminate vibrations and extraneous noise when the compressor is operating. The legs of the case are equipped with adjusting screws that allow you to set the equipment strictly horizontally, which is especially important for proper closing of the doors and operation of the system No Frostif it is provided by the model.
It is strictly forbidden to install the refrigerator close to a wall or furniture. For normal air circulation around the condenser, which is usually located on the rear wall, it is necessary to leave a gap of at least 5-7 centimeters on all sides. Insufficient ventilation leads to overheating of the radiator, increasing energy consumption and reducing the service life of the motor.
⚠️ Attention: If the refrigerator was transported at a temperature below +5°C, before turning it on, it must stand in a warm room for at least 4-6 hours. This is necessary to evaporate condensation formed inside the electrical components and prevent short circuits.
After the unit has settled and taken its place, you should wipe the internal chambers with a damp cloth using a weak solution of soda or a special dishwashing detergent. This will remove industrial dust and odors. Only after the chambers have completely dried can they be connected to the electrical network. It is recommended to use a separate socket with grounding, avoiding the use of extension cords and tees, since the starting currents of the compressor can be high.
☑️ Initial installation of the refrigerator
Adjusting the temperature in the refrigerator compartment
Main a parameter that requires user attention is the temperature in the refrigerator compartment. The optimal range for storing most products is considered to be from +2°C to +5°C. In models Pozis with mechanical control, adjustment is carried out by turning the thermostat located inside the chamber or on the top panel. The numbers on the scale (usually from 1 to 5 or from Min to Max) do not indicate degrees, but the cooling intensity.
The higher the number, the colder it will be in the chamber. However, you should not unnecessarily set the regulator to the maximum value, as this forces the compressor to work almost without interruption, which leads to its wear. Thermostat should turn off the motor-compressor when the set temperature is reached, ensuring cyclical operation. If you set the cooling to maximum, the rest cycle may not occur at all.
For models with electronic control, the setting is made through the panel on the door. Here you can set the exact value in degrees Celsius. It is recommended to set the value to +3°C or +4°C as the base value. If you notice that the food in the depths of the chamber begins to freeze, the temperature should be increased by one degree. Conversely, if the products spoil quickly, the value needs to be reduced.
| Knob position | Operating mode | Recommended application |
|---|---|---|
| Min / 1 | Minimum cooling | Warm season, light load |
| Average / 3 | Normal mode | Daily operation (standard) |
| Max / 5 | Intensive cooling | Loading a large volume of food |
| Off / 0 | Compressor shutdown | Defrosting or long-term shutdown |
Setting the freezer and the Super Freeze mode
The freezer compartment in refrigerators Pozis is designed for long-term storage of food at a temperature of -18°C and below. In most models, the temperature here is regulated together with the refrigerator compartment by one thermostat, but in two-compressor systems or models with electronics, independent settings are possible. For high-quality freezing, it is important that air circulates freely between products, so you should not fill the chamber to capacity immediately after turning it on.
One of the most useful functions is the Super Freeze (Super Freeze) mode. This mode is designed to quickly freeze fresh food or increase the supply of ice. When this function is activated, the compressor runs continuously, ignoring thermostat stop signals. The temperature in the chamber can drop to -24°C...-26°C, which allows you to create an ice crust on products that preserves their structure and beneficial properties.
You cannot always use the intensive freezing mode. This leads to excessive energy consumption and accelerated wear of parts. Activate the function Super Freeze 2-3 hours before loading fresh food and be sure to turn it off after 24 hours (or wait for automatic shutdown if the model is equipped with a timer). In some older models, the freeze mode switch has three positions: off, on, and auto.
What happens if you forget to turn off the Super Freeze?
If the Super Freeze mode is not turned off in time, the temperature in the freezer may drop below design standards, resulting in excessive freezing of the evaporator, difficulty opening drawers, and potential thermostat failure due to constant operation without rest cycles.
Features of setting up the No Frost system
Refrigerators Pozisequipped with the system No Frostdo not require manual defrosting, since moisture is removed from the chambers automatically. However, even such models require proper configuration and maintenance. The main rule for owners of equipment with this system is not to seal the ventilation holes inside the chambers and not to place products close to the back wall where the evaporator is located.
In models with electronic control, the “Vacation” or “Eco” function is often found. When activated, the temperature in the refrigerator compartment rises to +10°C...+15°C, which prevents the appearance of mold and odor, but saves energy. The freezer continues to operate normally. This is an ideal option for a long absence of owners, when there are no perishable products left in the refrigerator compartment.
Periodically, about once every six months, it is recommended to check the condition of the drainage channel, even in No Frost systems. Although the water evaporates, dust and small food particles can clog the outlet, causing puddles to form at the bottom of the compartment or under the refrigerator. Cleaning is carried out using a special brush or soft wire.
Interpretation of indicators and control panel
Modern control panels of refrigerators Pozis are equipped with a set of indicators that indicate the status of the device. Understanding their meaning helps you quickly diagnose problems. For example, a flashing temperature indicator or an audible signal often indicates that the door has remained open for more than 2-3 minutes, or the temperature inside the chambers has risen above the permissible limit.
The indicator Super Freeze (often indicated by a snowflake) is constantly on when the active freezing mode is turned on by the user. The compressor operating indicator (usually green) lights up when the motor is running. If this light does not come on at all, the refrigerator may be unplugged or the thermostat may be faulty. In models with a display, errors may be displayed in the form of alphanumeric codes such as F1, F2, etc.
If a fault code is displayed on the display or by flashing lights, do not ignore it. Each code corresponds to a specific component: temperature sensor, defrost system or control board. It is best to look for codes for your specific model Pozis (for example, RF-168, Mir, Shivaki) in the official instructions, as the designations may vary depending on the year of manufacture.
⚠️ Attention: If the indicators are flashing randomly or the refrigerator is making a series of short beeps for no obvious reason (an open door), try Disconnect the device from power for 10-15 minutes. This will allow you to reboot the electronic control module and reset the temporary software failure.
Typical errors during operation and their elimination
Even with correct initial settings, users often make mistakes during operation, which affects the quality of the refrigerator. One of the most common problems is installing hot or warm products. This creates excess load on the compressor and increases the humidity in the chamber, which leads to the formation of ice even in No Frost systems.
Another common mistake is violation of the product proximity and installation rules. Products should not block the flow of cold air. In refrigerators Pozis with a bottom freezer, cold air is often supplied from top to bottom or through special channels. If the shelves are filled to capacity, “warm pockets” may form in different areas of the chamber, where food will spoil while everything freezes in another part of the chamber.
It is also worth mentioning the problem of door seals. If the door does not close tightly due to debris getting into the grooves or deformation of the seal, the tightness is broken. The compressor will work in increased mode, trying to compensate for the heat flow, which will inevitably lead to its breakdown. Regularly checking the tightness of the door (test with a sheet of paper) should become a habit.
Why does the Pozis refrigerator work too loudly after setting up?
Increased noise immediately after switching on or changing settings may be associated with the compressor reaching maximum power to achieve the set temperature. Also check that the refrigerator's pipes are not touching a wall or furniture, and that it is level on the floor. If the noise persists after the temperature has stabilized, the compressor shock absorbers may need to be replaced or the fan checked. How often do you need to defrost a Pozis refrigerator with a drip system? will reach 5 mm. Frequent defrosting is not required, but it is also impossible to allow a thick layer of ice to form, as this impairs heat transfer and increases energy consumption.
How often should I defrost a Pozis refrigerator with a drip system?
Models with a drip system (“crying wall”) require manual defrosting approximately once every 6 months, or when the thickness of the ice crust on the back wall reaches 5 mm. Frequent defrosting is not required, but it should not be allowed to become fouled with a thick layer of ice, as this impairs heat transfer and increases energy consumption.
Is it possible to install a Pozis refrigerator in an unheated country house in winter?
Operation of most household refrigerators at ambient temperatures below +10°C is not recommended. At low temperatures, the oil in the compressor thickens, which makes starting and lubrication difficult, and the refrigerant may not circulate correctly. If the dacha is not heated, it is better to turn off the refrigerator, defrost it and leave it with the doors open until spring.
