Turning on a new household appliance always causes slight excitement, especially when it comes to complex equipment such as industrial or household refrigerator. Models from the brand Polair have proven themselves to be reliable equipment, but correct primary activation is critical to the longevity of the compressor. Errors at the startup stage can lead to a reduction in the life of the unit or incorrect operation of the cooling system in the future.
Before pressing the power button, you must make sure that the device has stood in an upright position for a sufficient amount of time after transportation. The oil in the compressor must drain into the crankcase, and the refrigerant must be distributed throughout the system. Ignoring this rule often causes the failure of expensive components.
In this article we will analyze in detail the algorithm of actions for various series of equipment Polair, consider the nuances of setting up the controller and answer frequently asked questions from users. The exact sequence of actions depends on the type of installed control panel (mechanical or electronic), so it is important to determine the modification of your device before starting work.
Preparation of equipment for the first launch
The first stage is not electricity, but physical preparation. After delivery, the refrigerator Polair must settle. If the device was transported in a horizontal position or with a strong tilt, the waiting time increases to 24 hours. For vertical transportation, 4-6 hours are enough.
Carefully inspect the case for mechanical damage that may have occurred during loading. Make sure that the protective film and shipping tapes are completely removed from the internal shelves and the evaporator. The presence of foreign objects inside the chamber may block air circulation.
Check the integrity of the door seals. They should fit snugly around the entire perimeter. If the door does not close tightly, the compressor will work in increased mode, trying to achieve the set parameters, which will lead to overheating.
⚠️ Attention: It is strictly forbidden to plug in the device if the power cord or plug is visible. This may result in a short circuit or electric shock.
Choose the correct installation location. The distance from the back of the refrigerator to the wall should be at least 10-15 cm to ensure free air convection. Side clearances are also important for models with side ventilation.
Connecting to the electrical network and checking the voltage
Refrigerators Polair are sensitive to voltage changes in the network. Before connecting, it is recommended to measure the parameters in the outlet using a multimeter. The rated voltage should be in the range of 220-240 Volts with a frequency of 50 Hz.
Use only a separate outlet with grounding. Prohibited use extension cords, tees and adapters, as they may not withstand the starting current of the compressor and cause a fire. If the outlet does not have a grounding, you need to call an electrician to organize it.
Industrial models often require connection through a separate circuit breaker. This provides additional protection and allows you to quickly de-energize the equipment in the event of an emergency without access to the common panel.
After connecting the plug to the socket, do not rush to start the unit right away. Allow the electronics to undergo initial diagnostics. On some models with electronic control, the power indicator may light up, but the compressor will start with a delay.
The switching algorithm for different types of control
Control interfaces for refrigerators Polair vary depending on the year of manufacture and series. Mechanical thermostats require manual turning of the knob, while electronic controllers require programming.
For mechanically controlled models, the process is simple: turn the thermostat knob clockwise until you hear a characteristic click. Usually this position is indicated by a number or a line. After this, you should hear the sound of the compressor starting.
In electronic models, you must press and hold the power button (often indicated by the power symbol) for 3-5 seconds. The controller screen should light up, displaying the current temperature inside the chamber.
☑️ Check before starting
If after switching on the indicators flash and no cold is generated, refer to the table of error codes below. Different flashing combinations indicate specific malfunctions of the sensors or compressor.
| Control type | Action to turn on | Success indicator | Possible problem |
|---|---|---|---|
| Mechanical | Turn the knob to the right | Relay click, compressor hum | Thermostat malfunction |
| Electronic (Eliwell) | Long press "Power" | Illuminated display | Controller failure |
| Digital controller | Button combination | Beep | Low battery |
| Remote (RU) | Activation on the remote control | The "Operation" lamp lights up | Communication loss |
It is important to understand that Digital controller can have a protective delay for turning on the compressor (usually 3-6 minutes) after power is applied. This is a normal protection function that prevents frequent engine restarts.
Setting the temperature mode
After a successful start, you must set the correct temperature. For refrigerators, the optimal range is considered to be from +2 to +6 degrees Celsius. For freezers - from -18 degrees and below.
Setting is carried out through the control panel. Use the Up and Down arrow buttons to change values. After selecting the desired parameter, press the confirmation button (often indicated as "Set" or "Enter").
Do not try to immediately set the lowest possible temperature. This will create excessive load on the system. It is better to set the average value and let the unit come into operation for several hours.
Control the cooling process using an independent thermometer placed on the middle shelf. The readings of the built-in sensor and the real thermometer may differ by 1-2 degrees, which is an acceptable error.
⚠️ Attention: A sharp change in temperature settings (more than 5 degrees at a time) can lead to the formation of condensation on products and damage to packaging. Change modes smoothly.
Initial loading and entering the mode
An empty refrigerator gains temperature faster, but this does not mean that it can be immediately filled with food. Allow the device to work at least one full cycle of turning the compressor on and off without load.
Loading should be done in small portions. If you place a large amount of warm food in the chamber, the compressor will work continuously, trying to compensate for the heat gain. This may cause it to overheat and trigger the thermal relay.
Distribute food evenly without blocking the ventilation holes. Cold air should circulate freely throughout the entire volume of the chamber. In models Polair with the NoFrost system, this is especially important to prevent the formation of ice jams.
The time to reach the operating mode depends on the volume of the chamber and the ambient temperature. On average, this process takes from 6 to 12 hours. Complete temperature stabilization at all points in the volume may take up to 24 hours.
What to do if the compressor hums but does not start?
If you hear a hum, but there is no characteristic click or start, the piston may be stuck or the start relay is faulty. Try unplugging the device for 15 minutes, then turning it on again. If the situation repeats, call a specialist.
Typical errors and ways to eliminate them
Even with proper activation, unforeseen situations may arise. Users often encounter flashing indicators or a lack of cooling when the fan is running.
One of the common problems is the door not closing tightly. In this case, the corresponding symbol may light up on the display, and the inside will feel warm. Check if there is anything obstructing the seal and level the device.
If an error code appears on the display (for example, E1, E2), this indicates a malfunction of the temperature sensor. In such cases, the refrigerator may go into emergency mode or completely turn off the compressor.
Noise during operation can also be alarming. A slight gurgling sound from the refrigerant is normal. However, a strong knock, vibration or piercing whistle requires immediate shutdown and diagnostics.
Why does the Polair refrigerator not turn on after a power surge?
Modern models are equipped with protection, but with a strong surge, the fuse on the control board could burn out or the controller itself could fail. Check the integrity of the fuse in the plug (if any) or call a specialist to diagnose the electronics.
How long should the compressor run in the first cycle?
When first started without load, the compressor can run for 30-40 minutes, then turn off for 10-15 minutes. When fully loaded, the operating time can increase to 1-1.5 hours. The main thing is that there are on and off cycles.
Is it possible to turn on a Polair refrigerator via a UPS?
It is not recommended to use a regular computer UPS, since the shape of the output signal (sine wave) may not be suitable for the compressor. You need specialized pure sine wave inverters designed for inductive loads.
What does a flashing light on the panel mean?
Frequent flashing usually indicates that the permissible temperature inside the chamber has been exceeded. This may be caused by an open door, warm food being loaded, or a faulty cooling system. Give the appliance time to restore mode.
Do you need to defrost the Polair refrigerator before turning it on for the first time?
No, new refrigerators are delivered dry. Defrosting is required only during operation if the model is not equipped with an automatic defrosting system. However, it is hygienically necessary to wipe the internal surfaces with a damp cloth before use.
