How should the Pozis refrigerator work when turned on for the first time: a complete guide

Purchasing a new refrigerator Pozis is an important step, and the first turning on equipment often raises questions even among experienced users. How to distinguish normal operation of equipment from a potential malfunction? How long should it take to cool down? Why does the compressor run non-stop and the indicators blink differently than in the instructions? These points are critical for the proper operation and durability of the device.

Unlike household appliances of other brands, refrigerators Pozis have a number of features in the first start-up algorithm. For example, the system No Frost in models Pozis RK-149 or Pozis RF-177 may make unusual sounds when initially setting climate zones. And in the line Pozis Fresh with a freshness zone, the first cooling cycle takes 20-30% longer due to additional sensors. Let's figure out what exactly should happen to the equipment in the first hours of operation, what parameters are considered normal, and what is worth paying attention to.

Important: the algorithms for the first start-up may differ slightly depending on the year of manufacture of the model and the firmware version. If your refrigerator was manufactured before 2022, some steps (such as sensor calibration) may occur differently. For accurate information, always check the passport of a specific model.

Preparing for the first turn on: what to do before starting

Before connecting the refrigerator Pozis to the network, you must complete several mandatory steps. Neglecting them can lead to malfunctions of the compressor or system No Frost.

First, after delivery, the equipment must stand in a vertical position for at least 4-6 hours (for models with an inverter-type compressor - up to 12 hours). This is because the oil in the system may have moved during transportation. In models Pozis RK-103 i Pozis RF-132 ignoring this rule often leads to increased noise in the first day of operation due to uneven distribution of lubricant.

• 📦 Unpack the refrigerator and remove all transport fastenings (staples, tapes, foam inserts). In models Pozis Fresh they often forget to remove the shelf clamps - this can interfere with normal air circulation.
• 🧹 Wipe the internal surfaces with a weak solution of soda (1 tablespoon per 1 liter of water). Avoid aggressive detergents - they can damage the antibacterial coating in models Pozis BioFresh.
• 🔌 Check the outlet: it must be grounded and withstand a load of at least 10A. For refrigerators with a Super Freeze function (for example, Pozis RF-188), a separate power line is recommended.
• ⚖️ Make sure that the refrigerator is level. The permissible slope is no more than 1°. In models with an electronic display (series Pozis Smart), an incorrect installation angle can cause false sensor errors.

Special Pay attention to the back wall of the refrigerator. In models with a system No Frost (for example, Pozis RK-167) there must be at least 5 cm between the wall and the furniture for normal air circulation. If this is not done, the compressor will work with increased load, which will reduce its resource.

⚠️ Attention: if the refrigerator Pozis was delivered in a horizontal position (lying down), the settling time before turning on increases to 18-24 hours. This is due to the risk of oil getting into the refrigerant circuit.

First minutes after switching on: what should happen

When you first connect the refrigerator Pozis to the network, a self-test procedure starts. In models with electronic control (series Pozis Smart i Pozis Fresh) this process takes from 30 seconds to 2 minutes. Here's what happens at this time:

1. Initialization of sensors. The refrigerator checks the functionality of the thermostats in the freezer and refrigerator compartments. In models with a freshness zone (for example, Pozis RF-177W), the humidity sensor is additionally tested.
2. Calibrating the compressor. Inverter models (Pozis RK-149 Inverter) determine the optimal starting power. In the first 5-10 minutes of operation, the compressor may make louder sounds than usual.
3. Activation of the No Frost system. The fans start running at full power to distribute the cold evenly. This may be accompanied by a short-term hum.

The following indicators may be displayed on the display (if any) at this moment:

In models without a display (for example, Pozis RK-103) the start of work is signaled only by the sound of the compressor starting and a slight vibration. If in the first 5 minutes after turning on the refrigerator is completely silent, check whether it is connected to the outlet and whether the circuit breaker in the panel has tripped.

Noise and sounds: what is normal and what is not

Refrigerators Pozis, especially during the first hours of operation, can make various sounds. Most of them are normal, but some signal problems. Let's take a closer look.

Normal sounds:

• 🔊 Compressor hum — constant low-frequency sound (20-50 dB). In inverter models (Pozis Inverter) it is more uniform, in conventional models - with pauses.
• 💨 Fan noise - a slight buzzing (especially noticeable in systems No Frost). In models Pozis RF-177 may sound like a “whistle” at high speeds.
• 💧 Gurgling or liquid pouring is the sound of refrigerant circulating through the tubes. More often heard in the first day.
• 🔄 Relay clicks -short metallic sounds when the compressor is turned on/off.

Sounds requiring attention:

• ⚠️ Knocking or rattling — may indicate incorrect installation (check the levelness of the floor) or loose compressor mounts.
• ⚠️ High-pitched whistle —a refrigerant leak is possible (especially if accompanied by poor cooling).
• ⚠️ A constant buzzing without pauses — the compressor is operating at maximum power. Reasons: high room temperature or sensor malfunction.

In models Pozis Fresh with a system Twin Cooling (double cooling) may be observed on the first day. periodic increase in noise up to 55 dB —this is normal, since the system sets up independent circuits for the refrigerator and freezer compartments. If the noise does not decrease after 24 hours, check whether the air channel is blocked by food.

Why is the new Pozis refrigerator louder than the old one?

Modern models (especially those with No Frost) have more powerful fans to distribute the cold evenly. In addition, new compressors often operate at higher speeds during the first 24 hours to quickly stabilize the temperature. After 2-3 days, the noise level should decrease to 38-42 dB (standard for Pozis).

If you are concerned about the noise level, use a sound level meter app (for example Decibel X). For refrigerators Pozis normal indicators:

• Day: up to 45 dB
• Night: up to 40 dB
• In mode Super freezing: up to 50 dB (temporarily)

Temperature conditions: how long does it take for the Pozis refrigerator to cool

One of the most frequently asked questions: “How long should the refrigerator run Pozis when first turned on to reach operating mode?" The answer depends on the model, the volume of the chambers and external conditions.

On average, the temperature stabilization process takes:

• 🕒 2-4 hours — for compact models (Pozis RK-103, volume up to 200 l)
• 🕓 6-8 hours — for medium refrigerators (Pozis RF-177, volume 250-350 l)
• 🕔 10-12 hours — for large models with No Frost and a freshness zone (Pozis RF-188 Fresh, volume from 400 l)

Important: these terms are valid at room temperature (20-25°C). If the refrigerator is turned on in a hot room (above 30°C), the cooling time increases by 30-50%. In models with the function Climate Control (for example, Pozis Smart), the Hot Climatemode is automatically activated, which speeds up the process.

To speed up the process, you can use several tips:

1. Do not load the refrigerator with food at once. Let it run empty for 2-3 hours.
2. Set the temperature control to the middle position (usually this is 3-4 on the scale or +4°C on the display).
3. Avoid opening the door frequently in the first 6 hours.

⚠️ Attention: if after 24 hours the temperature in the freezer has not dropped below -12°C, and the compressor is running without stopping, this may indicate thermostat malfunction or refrigerant leak. In this case, diagnostics from a service center are required.

Indication and errors: interpretation of signals on the display

Refrigerators Pozis electronically controlled and equipped with a self-diagnosis system that displays error codes on the display. During the first day of operation, temporary indicators may appear that are not malfunctions.

Normal indicators in the first 24 hours:

• 🔄 COOL or FREEZE —active cooling mode.
• ❄️ Super Cool or Super Freeze —accelerated cooling (turns off automatically).
• 🔋 HI or LO —high/low temperature in the chamber (disappears after stabilization).

Error codes that require attention:

• ⚠️ E1 —problem with the temperature sensor of the refrigerator compartment. In models Pozis Smart may appear when the sensor is frozen (solved by defrosting).
• ⚠️ E2 —faulty freezer compartment sensor. Often occurs due to incorrect installation (misalignment of the case).
• ⚠️ E3 - communication error between modules (requires a reboot or firmware update).
• ⚠️ E4 - problem with the system No Frost (fan or heater). In models Pozis RF-177 may appear when the air channel is blocked.

If an error appears on the display, first try the following:

1. Unplug the refrigerator for 5-10 minutes, then turn it on again.
2. Check that the doors are tightly closed (in models with magnetic seals sometimes require adjustment).
3. Make sure that the refrigerator is not standing close to the wall (there should be at least 5 cm of clearance).

In models without a display (for example, Pozis RK-103), malfunctions are indicated red indicator on the panel control or continuous hum of the compressor. If the indicator flashes for more than 5 minutes, this is a reason to contact service.

Typical mistakes when turning on the refrigerator for the first time and how to avoid them

Even experienced users sometimes make mistakes that complicate the first startup of the refrigerator Pozis. Here are the most common of them and ways to prevent them:

• ❌ Switch on immediately after delivery. As already mentioned, the refrigerator should sit for 4-12 hours. Otherwise, oil from the compressor may enter the refrigerant circuit, which will lead to increased wear of parts. If the refrigerator is on a slope, the door may not close tightly, causing the compressor to constantly run. Use a building level to check. increased wear of parts.
• ❌ Ignoring the level. If the refrigerator is on a slope, the door may not close tightly, causing the compressor to constantly run. Use a building level to check.
• ❌ Loading warm products. Placing uncooled dishes or a large number of products into the chamber immediately after switching on increases the cooling time by 30-50%.
• ❌ Blocking of ventilation grilles. In models with No Frost (for example, Pozis RF-188), blocking of the air channels leads to freezing of the evaporator and the error E4.
• ❌ Using extension cords. Refrigerators Pozis are sensitive to power surges. Connecting via an extension cord may cause a malfunction of the electronic module.

Another common mistake is incorrect temperature setting. Many users set the maximum cold (7 on the regulator or -24°C), believing that this will speed up the process. In fact, this leads to:

• Increased load on the compressor
• Freezing of food in the freezer
• Increase in energy consumption by 20-30%

Optimal settings for the first turn on:

• Refrigerator compartment: +4°C or position 3-4 on the mechanical regulator
• Freezer compartment: -18°C or position 4-5
• Mode Super freezing: activate only 6 hours after the first turn on

⚠️ Attention: in refrigerators Pozis with function Smart Diagnosis (models 2023+) incorrect settings on the first day may be recorded in the device memory as “standard”. This will lead to incorrect operation of energy saving algorithms. If you are in doubt about choosing a mode, use the factory settings (Default).

What to do in the first 24 hours: step-by-step checklist

To ensure that the first start of the refrigerator Pozis goes smoothly, follow this algorithm:

1. 0-2 hours: The refrigerator is running empty. Check that that:
   • The compressor has started (a slight hum is heard)
   • There are no errors on the display (except for temporary indicators HI/LO)
   • The doors close tightly (check the seals)

2-6 hours: You can load food, but not more than 50% of the volume. Avoid warm dishes. In models with No Frost check that the ventilation holes are not blocked.

6-12 hours: The temperature in the freezer should stabilize. chamber - up to -16°C, in the refrigerator - up to +5°C. If the values are far from normal, check the settings.

12-24 hours: The refrigerator should enter operating mode (10-15 minutes of operation, 5-10). minutes of rest). The noise does not exceed 45 dB.

If you notice deviations from this graph, use the table below:

For models with the function Smart Control (for example, Pozis Smart Inverter), you can use the mobile application Pozis Home for temperature monitoring and diagnostics. The application will show cooling graphs and warn about possible problems.

FAQ: answers to frequently asked questions about the first start-up

How long should the compressor run when first turned on?

In the first 2-4 hours, the compressor can work almost non-stop - this is normal. Then it should go into cyclic mode: 10-20 minutes of work, 5-15 minutes of pause. If the compressor does not turn off for more than 6 hours, check:

• Room temperature (should not be higher than 30°C)
• Door closure tightness
• Temperature settings (should not be at maximum)

In models with with an inverter compressor (Pozis Inverter), the pauses may be shorter (2-5 minutes), but the compressor itself is quieter.

Why does the new Pozis refrigerator hum a lot?

In the first day the hum may be louder than usual due to:

• Compressor calibrations (especially in inverter models)
• Fan operation No Frost at maximum power
• Refrigerant circulation through the system

If the noise does not decrease after 24 hours, check:

• Evenness of installation (use a level)
• Gaps between the refrigerator and the furniture (minimum 5 cm at the back)
• No vibration when touching the body

For models Pozis RF-177 and RF-188 the permissible noise level in the first day is up to 50 dB.

Is it possible to immediately load food into a new refrigerator?

Not recommended. Optimal algorithm:

1. The first 2 hours - the refrigerator runs empty.
2. The next 4 hours - you can load up to 50% of the volume, but only cooled products.
3. After 6-8 hours - full load.

Exception: models with the function Fast Cooling (for example, Pozis Smart) can be loaded after 1 hour, but no more than 30%.

What to do if the E1 error flashes on the display?

Error E1 indicates problem with the refrigerator temperature sensor. Try:

1. Unplug the refrigerator for 10 minutes, then turn it on again.
2. Check whether food is blocking the ventilation holes (in models with No Frost).
3. Make sure the door closes tightly (check the seal).

If the error does not disappears, the sensor may have frozen over. In this case:

1. Defrost the refrigerator for 12-24 hours (unplug it, leave the doors open).
2. Wipe the sensor (usually it is located on the back wall of the refrigerator compartment).
3. Turn on the refrigerator again.

If E1 lights up after defrosting, the sensor needs to be replaced (contact the service center).

How to check if the freezer is working correctly?

To check:

1. Place the thermometer in the center of the freezer (for example, between products).
2. After 12 hours, check the readings. Norm for most models Pozis:
• Pozis RK-103: -16...-18°C
• Pozis RF-177/188: -18...-20°C
• Pozis Fresh: -20...-22°C (in mode Super
