Modern two-chamber models Atlant with a system No Frost or combined cooling are often equipped with two independent compressors. This solution allows the cooling circuits of the refrigerator and freezer compartments to be separated, providing more precise temperature control. However, sooner or later the owners are faced with the question: how to correctly turn off such a unit? Situations can be different: planned defrosting, general cleaning, long-term absence of owners or preparation for transportation.
Incorrect shutdown of equipment can lead to serious consequences, including failure of the compressor or violation of the tightness of the system. Unlike single-circuit models, it is important to take into account the operating features of two motors. Inverter and classic piston engines require a different approach to stopping and subsequent starting. Understanding these nuances will extend the life of your equipment.
In this article we will analyze in detail the algorithm of actions for safely turning off the refrigerator Atlant. We will look at physical methods of de-energizing, software settings and rules for preparing for transportation. We will also pay attention to what absolutely cannot be done, so as not to damage the refrigerant or electrical part.
Why do you need to turn off a two-compressor refrigerator
The main reason for a complete shutdown is the need for defrosting. Despite the presence of the system No Frost, ice may accumulate in the evaporators over time, especially if the tightness of the door seals is broken. In models with a drip system, defrosting is required regularly. A complete power outage is necessary for at least 24 hours to completely evaporate moisture from hard-to-reach units.
Another common scenario is a long absence of owners. If you are going on vacation or a business trip for more than a month, leaving a running refrigerator unattended is risky. Power surges or leaking water supply hoses (if there is a dispenser) can lead to fire or flooding of neighbors. In such cases, it is better to de-energize the equipment.
The third important aspect is transportation. When moving, the refrigerator must not only be turned off, but also properly prepared. Dual-compressor models Atlant are sensitive to the position during transportation, since oil from the compressors can get into the refrigerant circuit. This requires special attention to the settling time before restarting.
⚠️ Attention: Do not try to turn off only one of the two compressors, leaving the second one running, unless this is provided for in the special “Vacation” mode. Mechanical interference with the operation of one motor will upset the pressure balance in the system.
Physical disconnection from the power supply
The most reliable and safest way to turn off the refrigerator is to physically break the electrical circuit. In dual-compressor models, both motors are powered from the same outlet, so it is enough to remove the plug from the network. However, this must be done correctly to avoid sparking or damaging the contacts.
First, make sure your hands are dry and the floor around the outlet is not flooded. Grasp the plug body, not the wire, and remove it smoothly, without jerking. If the fork is tight, you can rock it slightly from side to side. Sudden movements can damage the internal contacts of the socket.
If access to the socket is difficult or it is located high, the machine can be used in an electrical panel. Find the appropriate switch labeled “Kitchen” or “Outlets” and turn it to the “Off” position. This is especially convenient if the refrigerator is built into the kitchen unit.
- 🔌 Always pull the plastic body of the plug, avoiding tension on the cable itself.
- ⚡ Before removing the plug, make sure that there are no active errors on the control panel.
- 🛑 Do not use wet cloths or gloves when contact with the electrical network.
Using the “Holiday” mode and electronic control
Many modern models Atlant with electronic control are equipped with a special “Holiday” function. This mode does not turn off the refrigerator completely, but puts it into an economical state. The freezer compartment continues to operate in normal mode, keeping food frozen, and the refrigerator compartment goes into standby mode with a temperature of about +15°C.
The mode is activated through the control panel. Typically you need to press and hold the snowflake or "H" button for 3-5 seconds. The corresponding indicator will light up on the display. In this state, energy consumption is reduced to a minimum, and the risk of unpleasant odors in the empty chamber is eliminated.
It is important to understand the difference between the "Vacation" mode and a complete shutdown. If you need to clean the floors under the refrigerator or go away for a year, the Vacation mode will not work - it requires a network connection. Complete shutdown is necessary for defrosting and transportation.
Preparing for defrosting and cleaning
The process of defrosting a two-compressor refrigerator requires consistency. First you need to empty the chambers of food. If you plan to store food while cleaning, prepare insulated containers or ask neighbors to take some of the supplies.
After removing food and turning off the power, open all doors. This will ensure air circulation and speed up the melting of the ice. Do not use hair dryers, knives or other sharp objects to speed up the process - this can damage the evaporator, especially in the compressor operating area.
While defrosting is in progress, you can start cleaning the external surfaces and seals. Use a soft cloth and neutral detergent. Aggressive chemicals can corrode plastic and rubber parts, which will lead to loss of tightness.
☑️ Checklist for preparing for defrosting
Rules for transportation and storage without cold
If the refrigerator Atlant turns off for transportation, it is critical to observe time intervals. After operation, the compressors are under pressure and the oil is distributed throughout the system. A sharp step after transportation can lead to water hammer.
During transportation, the refrigerator must be in a vertical position. An inclination of more than 40 degrees is prohibited, as this will ensure that oil flows into the refrigerant circuit. If it is impossible to transport vertically, the tilt angle should be minimal and the transportation time should be short.
After delivery and installation in a new place, the refrigerator cannot be turned on immediately. Two-compressor models require time to stabilize temperatures and drain oil back into the engine crankcases.
| Transportation conditions | Settling time (summer) | Settling time (winter) |
|---|---|---|
| Vertical | 2-4 hours | 4-6 hours |
| At an angle of up to 40° | 6-8 hours | 10-12 hours |
| Horizontally (not recommended) | 12+ hours | 24+ hours |
⚠️ Attention: If the refrigerator was transported in an open car or unheated body in winter, allow it to warm up to room temperature for at least 4 hours before turning it on. Condensation inside the electronics can cause a short circuit.
Typical mistakes when turning off equipment
One of the most common mistakes is trying to immediately turn on the refrigerator after defrosting or transporting it. Owners forget that the compressor needs time to return oil. Starting “dry” or with oil in the circuit significantly reduces the engine life.
Another mistake is pulling the plug by the wire. Over time, this leads to a break in the wires inside the cable at the base of the plug. Such damage is dangerous due to sparking and melting of the insulation. Always grasp the plastic part only.
Also, users often ignore the need to secure the doors during transportation. If the doors of a two-compartment refrigerator are opened while traveling, they may come off or damage the hinges. Be sure to use adhesive tape or a special shipping tape.
What to do if the refrigerator makes a strange sound after turning on?
If after turning on you hear gurgling or hissing, this is normal, the refrigerant is moving. If you hear a metallic knock or buzz that does not stop after 5 minutes, immediately turn off the device and call a technician.
Frequently asked questions (FAQ)
Is it possible to turn off an Atlant refrigerator with two compressors at night?
Do not do this regularly recommended. Frequent on and off cycles place unnecessary stress on compressor starting currents. If the goal is to save energy, this is ineffective, since after turning on the refrigerator will work at maximum to restore the temperature, consuming a lot of energy.
Do you need to remove the plug from the socket if there is a button on the case?
In most models Atlant the button on the case is a control or defrost button, not complete circuit break. It may leave electronics energized. For complete safety (fire and electrical), it is better to remove the plug from the socket.
How long can you not turn on the refrigerator after washing?
After normal defrosting and washing, it is enough to wait 1-2 hours for the moisture on the contacts to dry and the water to evaporate from pallet After transportation, the waiting time depends on the transportation position (see table above).
Does frequent shutdown affect the service life of two compressors?
Yes, it does. Compressor life is measured by the number of operating hours and starting cycles. Each start means wear and tear on the starting winding and mechanics. However, scheduled shutdowns for defrosting (1-2 times a year) will not cause significant harm.
