Correct startup refrigeration equipment after scheduled or emergency defrosting is a critical stage on which the durability of the compressor and the quality of freezing products directly depend. Many equipment owners Atlant make the fatal mistake of starting the unit immediately after wiping off the ice inside the chambers. Such a rush can lead to water hammer in the cooling system or overload of the engine, since the coolant and oil must return to the normal operating zones.
Two-chamber models of the Belarusian manufacturer, be it the classic series or the line with the system No Frost, have their own design features for freon circulation. Ignoring the rules for initial switching on after inactivity negates all the benefits of the cleaning performed. In this article, we will analyze in detail the algorithm of actions that will allow you to safely start your refrigerator and avoid expensive repairs.
Why you cannot turn on the refrigerator immediately after defrosting
During the defrosting period, when the unit is disconnected from the network, the oil in the compressor gradually flows into the cooling circuit. If you turn on the device immediately, the motor will start “dry” or with insufficient lubricant, which will cause critical wear of the rubbing parts. In addition, liquid refrigerant that has not had time to evaporate in the heat exchanger can enter the compressor, causing water hammer.
The equipment Atlant is equipped with reliable, but sensitive to operating conditions, motors. A sudden start in the presence of condensation on the electrical contacts also carries the risk of a short circuit. The moisture remaining in hard-to-reach places after the ice melts must completely evaporate so as not to damage the electronic control board or wiring.
Downtime is necessary not only for the oil to drain, but also to equalize the pressure in the system. Refrigerant must take its original position in the condenser and evaporator. Violation of this physico-chemical balance will result in the refrigerator working overload, trying to gain temperature, but will not be able to do this effectively.
⚠️ Attention: An attempt to force the refrigerator to start less than 2 hours after defrosting may be grounds for denial of warranty service. Service centers record traces of the compressor starting immediately after defrosting based on the condition of the oil.
There is a common myth that modern models do not have this drawback. However, the physics of operation of piston and inverter compressors used in Atlantakhdictates uniform safety rules for all climate control equipment.
Waiting time: how long should a refrigerator stand?
The main question that arises among users: how long should a refrigerator stand before turning on? For two-chamber models Atlant the minimum permissible rest interval after complete defrosting is 2 hours. This time is necessary for the oil to drain back into the compressor crankcase.
However, there are nuances that depend on the defrosting conditions. If you defrosted the unit in a cold room or in winter with the window open, the waiting time should be increased to 4 hours. A sharp temperature change requires longer acclimatization of metal and plastic.
If the refrigerator was transported in a horizontal position before defrosting, the standing time should be increased to 8–12 hours. In this position, the oil is guaranteed to flow into the pipelines, and it takes much longer to return it than when standing idle vertically.
The table below will help you navigate the optimal waiting time depending on the situation:
| Situation | Minimum waiting time | Recommended time |
|---|---|---|
| Scheduled defrosting (vertical) | 2 hours | 3-4 hours |
| Defrosting in a cold room | 3 hours | 4-5 hours |
| Transportation lying down + defrosting | 6 hours | 8-12 hours |
| Emergency shutdown (short) | 15 minutes | 30 minutes |
Preparing for the first start: checklist of actions
Before inserting the plug into the socket, you need to make sure that the interior of the refrigerator is completely ready for use. The presence of moisture is the main enemy of electrical appliances. Thoroughly wipe all surfaces, including rubber door seals and water drainage channels.
Check the integrity of the power cord and plug. After manipulating with water, drops may remain on them, which must be removed with a dry cloth. Make sure that the refrigerator is installed level, without distortions, which can cause vibration and noise when the compressor operates.
☑️ Check before turning on
Pay special attention to the drainage hole. In two-chamber models Atlant it often becomes clogged with crumbs or mucus after defrosting. Clean it with a special brush or soft wire so that condensation does not accumulate at the bottom of the refrigerator compartment.
Do not load food immediately. An empty refrigerator will reach temperature faster and easier. Loading warm products at the time of first startup will create excess load on the system, forcing the compressor to work at its limit.
Step-by-step instructions: how to turn it on correctly
The process of turning on a two-chamber refrigerator Atlant is simple, but requires consistency. First, make sure that the thermostat or electronic control panel is in the off position (usually the “0” or “Off” position). Only after this, connect the power cord to the network.
If your model is equipped with a mechanical regulator, turn the knob to the position corresponding to the average temperature (usually number 2 or 3 out of 5). For electronic models, press the power button and wait until the indicators light up. Do not immediately set the “Super Freeze” mode.
⚠️ Attention: Do not use extension cords, low-quality surge protectors or tees to connect the refrigerator. Direct connection to a separate grounded outlet is the only correct solution for powerful compressors.
After turning on, listen to the operation of the unit. The compressor should start smoothly, without loud knocking or humming noises. In the first minutes of operation, you may hear the sound of gurgling or liquid flowing - this is normal, the refrigerant begins to circulate through the system.
What should you do if the refrigerator hums immediately after turning on?
If the humming is very loud and is accompanied by strong vibration, check whether the shipping bolts have been removed (if the model is new) and whether the unit is level. Twist the legs to level them. If the noise does not stop after 10-15 minutes, the compressor may need diagnostics.
Allow the refrigerator to idle for at least 2-3 hours. During this time, it should enter operating mode and turn off (or reduce speed if it is an inverter model). Only after reaching the target temperature can you start loading products.
Setting the temperature after inactivity
Correct setting of the thermostat is the key to economical operation and safety of products. In two-chamber models Atlant with one compressor, the temperature in the refrigerator and freezer compartments is interconnected. Adjustment is carried out with one knob or one button.
For everyday use, it is recommended to set the average values. On mechanical models, this is usually the position of the knob between the numbers 2 and 3 (or 3 and 4, depending on the scale). In electronic models, the optimal temperature is +3...+4°C in the refrigerator compartment and -18°C in the freezer.
You should not immediately set the minimum possible temperature after switching on. This will force the compressor to work continuously, trying to cool the heated walls of the chamber, which will lead to overheating and increased energy consumption.
If your model has a function Super freezing, turn it on only if you need to freeze a large amount of fresh food. After completing the task (usually after 24 hours), the mode must be turned off manually, if it is not provided automatically.
Frequent startup errors and their consequences
One of the most common mistakes is ignoring the instructions and turning on the device immediately after washing. Users often forget that water may have gotten into the insulation or contacts and rush to load the products. This risks failure of not only the compressor, but also the defrosting system.
The second mistake is installing the refrigerator close to a wall or furniture. After defrosting, it is important not only to turn it on, but also to ensure the correct heat exchange conditions. The rear grille of the condenser must have a gap of at least 5–10 cm for free air circulation.
The third mistake is the use of aggressive chemicals when cleaning before turning on. Residues of bleach or abrasives can damage plastic parts and rubber seals, and their vapors can damage metal elements of the cooling system.
Loading a large volume of warm food into a refrigerator that has just been turned on is stressful for the system. The unit will work for wear, trying to compensate for the heat introduced by the products, which can lead to the formation of a “snow coat” even in models with No Frost.
Diagnostics: is everything working normally?
After the refrigerator Atlant has worked for several hours, conduct a visual inspection. Assess the uniformity of cooling: there should be no warm zones in the refrigerator compartment, and there should be no thawed food in the freezer (if they were there).
Check the operation of the No Frost system (if there is one). The air should circulate freely, without whistling or strong wind noise. There should be no ice or drops of water dripping onto the food on the back wall of the refrigerator compartment.
Pay attention to the temperature of the case. The side walls may become slightly warm - this is normal, there are defrost circuits or a condenser there. However, if the engine compartment heats up to the point where it is impossible to hold your hand, or you smell a burning smell, the device must be turned off immediately.
How long does it take for the refrigerator to gain temperature after defrosting?
Usually, a two-chamber Atlant refrigerator takes 2 to 4 hours to reach the operating cooling mode with empty chambers. Complete freezing of the products and stabilization of the temperature throughout the entire volume can take up to 12–24 hours.
Is it possible to turn on the Atlant refrigerator if it has been standing in the cold?
It is strictly forbidden to turn on the unit immediately after bringing it in from the frost. It needs to sit in a warm room for at least 4–6 hours (preferably a day) so that the oil warms up and the condensation inside the electronics evaporates. Turning on a cold compressor will lead to its breakdown.
What to do if after turning on the refrigerator does not freeze?
If the temperature does not decrease within 5-6 hours of operation, check the tightness of the door, the position of the thermostat and the presence of voltage in the network. If all the parameters are normal, but there is no cold, there may be a freon leak or a compressor breakdown, you need to call a technician.
Do you need to wash the refrigerator before turning it on for the first time after purchase?
Yes, a new refrigerator also requires preparation. It needs to be washed with warm water and soda or a weak solution of vinegar to remove the smell of plastic and factory dust, and allowed to dry before plugging it in.
