Starting a new one or a long time idle refrigeration equipment of the brand Polair requires adherence to a clear algorithm of actions to guarantee a long service life of the compressor and the safety of products. Simply plugging the plug into the socket is only the final step, which is preceded by an important period of adaptation of the equipment to the temperature conditions of the room. Ignoring the rules of transportation and settling time can lead to failure of the piston group or leakage of refrigerant.
Owners of commercial and household equipment are often faced with the need to correctly configure the controller, since the factory settings may not correspond to specific operating conditions. In this article we will analyze in detail the preparation process, connection steps and ways to eliminate common errors that may occur during the first start.
Particular attention should be paid to diagnosing the system before applying voltage. If the equipment was delivered in a horizontal position or at subzero temperatures, the internal components need time to return to working condition. Violation of this rule is the most common cause of failure of an expensive compressor in the first days of use.
Preparation of equipment before first start-up
Before you think about connecting electricity, it is necessary to conduct a thorough visual inspection of the case and internal chambers. Make sure that there are no mechanical damage, dents or cracks on the doors, seals and evaporator that may have occurred during transportation. Any defects in the rubber seals can lead to chamber leaks and constant operation of the compressor.
A critically important step is to observe the time interval between delivery and switching on. If the unit was transported in an upright position, the minimum settling time is 2–3 hours. In the case of horizontal transportation, this period increases to 8–12 hours so that the oil flows into the compressor crankcase.
⚠️ Attention: If the equipment was brought in from frost, do not turn it on immediately. Sudden temperature changes can cause condensation on electrical contacts, resulting in a short circuit. Allow the equipment to warm up to room temperature for 4–6 hours.
After settling, it is necessary to rinse the internal chambers with warm water with the addition of a mild detergent. Factory grease and dust must be completely removed, as they can impart an extraneous odor to the products. Wipe surfaces with a soft cloth, avoiding the use of abrasive sponges.
Correct connection to the power supply
The organization of power supply for refrigeration equipment requires compliance with safety standards. For connection, it is recommended to use a separate grounded socket located in close proximity to the unit. The use of extension cords, tees and low-quality surge protectors is strictly not recommended, since compressor starting currents can cause heating of the contacts and fire.
Make sure that the electrical parameters meet the requirements specified on the technical plate (nameplate) of the device. Usually this is voltage 220-230V with frequency 50 Hz. Voltage surges are detrimental to the electronic control unit, so if the network is unstable, it is worth considering installing a stabilizer.
The switching process is as follows:
- 🔌 Make sure that the plug is firmly inserted into socket and does not wobble.
- 🔍 Check the condition of the power cable for creases or melting.
- ⚡ If there is a separate power switch on the case, move it to position
ONorI. - 🔊 Listen: after a few seconds it should a characteristic click of the relay will be heard and the compressor will start.
It is important to ensure free circulation of air around the condenser. The gap between the rear wall of the refrigerator and the wall should be at least 7–10 cm. Overheating of the condenser due to poor ventilation, it leads to an increase in pressure in the system and an emergency shutdown.
Setting the temperature mode and controller
Most modern models Polair are equipped with electronic controllers (for example, series Evco or Dixell), which allow you to accurately regulate the temperature. After power is applied, the display will show the current temperature inside the chamber. The default mode is usually +5°C, but this can be changed depending on the type of products you are downloading.
To change settings, you must press and hold the install button (often indicated as Set) for 3-5 seconds. The temperature value will start flashing on the display. Using the navigation buttons, set the required value. After confirming the settings, the controller will go into standby mode.
There are several important parameters that may require adjustment:
- ❄️ Differential —the temperature difference between turning on and off the compressor.
- ⏱️ Fan delay —the time after which the fan turns on after starting compressor.
- 🌡️ Sensor correction —calibration of readings if the real thermometer shows different values.
| Product type | Recommended temperature | Max. storage time |
|---|---|---|
| Vegetables and fruits | +4...+6 °C | 3-7 days |
| Dairy products | +2...+4 °C | 2-5 days |
| Chilled meat | 0...+2 °C | 1-3 day |
| Frozen semi-finished products | -18 °C and below | up to 12 months. |
You should not set the minimum possible temperature immediately after turning on the empty chamber. This will create excessive load on the system. It is optimal to set the average value, load the products and only then adjust the mode if necessary.
☑️ Check before loading products
Stabilization period and first load
After turning on the empty refrigerator, a period of temperature stabilization must pass. For medium-temperature storage chambers it is about 2-3 hours, for low-temperature freezers - up to 6-8 hours. Loading products before reaching operating temperature will lead to their spoilage and increase the operating time of the compressor.
Foods should be loaded gradually. Do not completely fill the chamber with hot or warm dishes. Thermal load this may cause the formation of large amounts of condensation and a temporary increase in temperature above critical values. Products should be laid out so that they do not block the air duct openings.
⚠️ Attention: Do not load food into the chamber until the internal temperature has dropped to the set value. Early loading disrupts the circulation of cold air.
During the first day of operation, the equipment may make various sounds: gurgling of refrigerant, cracking of plastic during expansion/contraction, humming of the compressor. These are normal operating sounds. However, if you hear a loud knock or metallic clanging, you should immediately turn off the device and contact service.
Why does the refrigerator work non-stop on the first day?
In the first 24 hours, the compressor can work almost continuously, trying to cool not only the air, but also the walls of the chamber, as well as the body itself. It is normal if the temperature inside gradually decreases. If there is no cold after 24 hours, this is a malfunction.
Decoding error codes on the display
Modern controllers Polair equipped with a self-diagnosis system. If a malfunction occurs, an error code appears on the display instead of the temperature. Understanding these codes allows you to quickly identify the problem and avoid food damage.
The most common error codes:
- 🚫 E1 — Malfunction of the evaporator temperature sensor. The sensor needs to be replaced.
- 🌡️ E2 — Error in the temperature sensor in the chamber. The readings are outside the permissible range.
- 💨 E3/E4 — Problems with the defrost sensor or compressor overheating.
- 📡 E5 — Communication error between the controller and external modules (for composite units).
If the display shows an error, try rebooting the system: disconnect the refrigerator from the power supply at 10-15 minutes, then turn it on again. If the error recurs, the equipment cannot be operated, as this may lead to defrosting of the food or breakdown of the compressor.
In some cases, the error may not be caused by a breakdown, but by a temporary failure in the electronics or a broken contact due to vibration. Check the integrity of the wires connecting to the sensors, especially if the camera has been subjected to mechanical stress.
Typical problems and methods for eliminating them
During operation, users may encounter a number of situations that are not breakdowns, but require intervention. For example, if a refrigerator does not turn off, check the tightness of the door and the integrity of the magnetic seal. Also, the reason may be that the unit is installed too close to heat sources (radiators, stoves).
The formation of ice on the back wall or products often indicates a violation of operating rules. Frequently opening the door, loading warm food, or not closing the chamber tightly allows moisture to enter, which freezes on the evaporator. On models with manual defrosting, this requires periodic shutdown to remove ice.
If you notice that the equipment is making a lot of vibration noise, check the adjustment of the support legs. The unit must stand strictly horizontally. To check, use a building level or simply shake the housing - it should not wobble.
⚠️ Attention: Never use sharp objects (knives, screwdrivers) to chip ice inside the chamber. Damage to the evaporator will lead to an immediate release of freon and expensive repairs, which are often not economically feasible.
It should be remembered that technical specifications and control interfaces may vary depending on the year of manufacture of the model. Always check the data sheet of a specific product, as the manufacturer has the right to make changes to the design without notice.
Frequently asked questions (FAQ)
How long does it take for the Polyre refrigerator to gain temperature after switching on?
For medium-temperature chambers, the time to reach the mode is 2–4 hours. Freezers can reach a temperature of -18°C within 6–10 hours, depending on the volume of the chamber and the ambient temperature.
Why does the refrigerator turn on and then immediately turn off?
This may indicate a malfunction of the compressor start relay, low voltage in the network, or an overload of the system. If it happens frequently, you need to turn off the device and call a specialist.
Is it possible to turn on the Polair refrigerator immediately after delivery?
It is strictly not recommended. The oil should drain into the compressor and the refrigerant should be distributed throughout the system. The minimum settling time is 3 hours, the optimal is 12 hours.
What to do if error E1 is on?
Error E1 means a malfunction of the temperature sensor. Try rebooting the refrigerator. If the error remains, the sensor must be replaced at an authorized service center.
Is it normal that the side walls of the refrigerator heat up?
Yes, this is normal. In modern models, the capacitor is often built into the side walls of the case. Heating to 40–50°C in the active phase of compressor operation is the normal mode of heat transfer.
