Operation of brand refrigeration equipment Atlant requires periodic maintenance, the key stage of which is a complete shutdown of the power supply and subsequent defrosting. Despite the fact that many modern models are equipped with automatic defrost systems, ignoring the scheduled shutdown can lead to a decrease in heat transfer efficiency and increased energy consumption. Equipment owners need to clearly understand the difference between a short-term blackout and the deep defrosting procedure, since these processes require different approaches to organizing safety.
The process of preparing the unit for "rest" begins long before you unplug the cord from the outlet. Critical important plan the time in advance work, since the full cycle, including defrosting the evaporator, washing the chambers and drying, can take from 12 to 24 hours. This time is necessary so that the ice crust accumulated on the walls of the evaporator completely melts naturally, and there is no moisture left inside the system that can cause corrosion or a short circuit when restarted.
In this manual we will analyze in detail the algorithm of actions for various modifications of refrigerators Atlant, including models with a drip system and technology No Frost. Following the sequence of operations will avoid damage to the compressor, deformation of the plastic elements of the internal volume and the appearance of unpleasant odors in the future. Let's consider the technical nuances that are often overlooked when independently servicing household appliances.
Preparatory stage before turning off the power
The first step is to free the internal space of the refrigerator and freezer compartments from food. All perishable goods should be removed, since during the defrosting process the temperature inside the chambers will rise above the permissible storage values. Removable shelves and boxes made of plastic or glass should be removed immediately to prevent them from cracking due to temperature changes or accidental impact during cleaning.
Necessary also free up space around the refrigerator. Move the housing away from the wall at least 50-70 centimeters to provide free access to the rear condenser grille and compressor compartment. This action is necessary for high-quality ventilation and safe cleaning of hard-to-reach places where dust often accumulates, impairing heat transfer.
⚠️ Attention: It is strictly forbidden to try to speed up the process of thawing ice using a hairdryer, hot water or sharp objects (knives, screwdrivers). Mechanical impact can lead to breakdown of the evaporator tubes through which the refrigerant circulates, which will lead to expensive repairs or complete disposal of the unit.
Prepare a container to collect melt water. Depending on the design of your model Atlant, this may be a baking tray installed under the freezer, or special gutters for draining condensate. Stock up on absorbent rags or towels in advance to quickly remove water flowing onto the floor, preventing swelling of the floor covering or moisture getting on electrical contacts.
Sequence of turning off the power supply
The procedure for turning off the power is simple, but requires compliance with a certain sequence to preserve the resource of the electronic control module. First you need to set the thermostat to the "0" or "Off" position. On electronically controlled models, press and hold the power button on the display panel until the lights turn off. This allows the system to correctly complete the current cycle of compressor operation.
Only after the unit has entered standby mode can you remove the power cord plug from the electrical outlet. Important: Never pull on the cord itself, pulling out the plug, as this can lead to a break in the internal wires and damage to the insulation. If the outlet is located in a hard-to-reach place, use an extension cord or temporarily move furniture aside to gain direct access to the power source.
For models with the system No Frost the pause before turning it on again should be at least 10-15 minutes, however, with complete defrosting, this interval increases significantly. If you plan to simply turn off the refrigerator while on vacation, just disconnect the cable, first making sure that the doors are tightly closed, although modern recommendations from manufacturers advise leaving them slightly open for ventilation.
Defrosting technology for different cooling systems
The defrosting algorithm directly depends on the type of cooling system installed. In refrigerators Atlant with a drip system (crying evaporator), the main ice forms on the back wall of the refrigerator compartment and on the floor of the freezer. Here the process is faster, since the icing area is usually smaller. It is enough to leave the doors open, and after a few hours the ice will begin to melt rapidly.
Units with the No Frost system (or Low Frost) require a more careful approach. Although they are equipped with automatic defrosting heating elements, with manual defrost it is necessary to give time to the air ducts hidden behind the plastic panels to warm up. Ice can be hidden in hard-to-reach places in ventilation ducts, and its complete removal is critical for proper air circulation.
The table below shows comparative characteristics of the processes for different types of systems:
| Parameter | Drip system | No Frost system | Combined |
|---|---|---|---|
| Defrost time | 8-12 hours | 12-24 hours | 12-18 hours |
| Ice location | HK back wall, MK floor | Evaporator behind the panel | MK floor and rear wall |
| Risk of damage | High (thin evaporator) | Average (plastic elements) | Average |
| Frequency of procedures | 1-2 times a year | 1 time a year (prevention) | 1 time a year year |
When working with a freezer pay special attention to the condition of the rubber sealswhich, with prolonged contact with melting water, may lose elasticity. After the ice has completely melted, it is recommended to wipe them with a weak solution of vinegar or a special rubber care product to extend their service life.
Cleaning the drainage system and removing moisture
One of the most common reasons for the appearance of puddles under the refrigerator or the formation of a “fur coat” in the future is clogging of the drainage hole. In refrigerators Atlant it is usually located at the bottom of the rear wall of the refrigerator compartment. During defrosting, the bulk of the condensate drains through it, so its cleanliness is vital.
To clean, use a soft rubber bulb or a special flexible brush-brush, which is often included with the equipment. Do not use metal wires, as they can easily pierce the plastic drainage tube located inside the housing. Rinse the channel with warm water, pouring it through the funnel, and make sure that the water flows freely into the drip tray above the compressor.
☑️ Checklist for preparing for washing
After the ice has melted, thoroughly wipe all surfaces dry. Leftover moisture in corners or under drawers can be an ideal breeding ground for bacteria and mold. Pay special attention to the corners of the freezer, where water can stagnate due to the design features of the tray.
Sanitary treatment of internal chambers
After moisture has been removed, the disinfection stage begins. To wash the interior surfaces of the refrigerator Atlant it is best to use a baking soda solution (1 tablespoon per 1 liter of water) or a mild soap. Aggressive chemicals, abrasive powders and solvents can damage the plastic coating and leave a persistent chemical odor that is transferred to the products.
Removable elements - glass shelves, plastic containers and bottle holders - should be washed separately in the bathroom or under the tap. Before installing the glass back into the chamber, it must be completely dry and warmed up to room temperature to avoid thermal shock when the device is turned on.
⚠️ Attention: When cleaning, it is strictly not recommended to use chlorine-containing products (for example, "Belizn") to treat plastic parts. Chlorine reacts with polymers, making them brittle and brittle, which leads to rapid failure of drawers and shelves.
To remove persistent odors, if they have already appeared, you can use activated carbon laid out in a saucer, or special odor absorbers. After wet cleaning, be sure to wipe all surfaces with a dry, clean cloth so that there are no streaks or drops of moisture left.
Rules for restarting and starting up
Before turning on the refrigerator Atlant after defrosting, make sure that it is completely dry and all removable elements are in place. Doors must be tightly closed. Connection to the network should be done only after the equipment has been turned off for as long as it was working before (or at least several hours) so that the oil in the compressor flows into the crankcase if transportation was carried out. With normal defrosting, 15-30 minutes are enough.
It is better to do the first start without loading food. Let the refrigerator run idle for 2-3 hours until it reaches operating temperature and automatically turns off (or goes into keep warm mode). This will allow you to check the tightness of the system and the correct operation of the thermostat.
Why can’t you load food right away?
Loading warm food or a large amount of food into a refrigerator that has just been turned on causes the compressor to wear out without stopping, which can shorten its service life. Let the unit return to mode.
If, after turning on, you hear unusual sounds (gurgling, loud clicks) or notice that the refrigerator does not turn off for more than 5-6 hours, this may indicate a malfunction. In normal operation, modern models Atlant gain temperature quickly enough thanks to efficient refrigerants.
Preservation of the refrigerator during long-term inactivity
If you need to turn off the refrigerator Atlant on for a long period (for example, when moving or being away for a long time), defrosting alone is not enough. After thorough washing and drying (drying), the refrigerator and freezer doors should not be left tightly closed.
Inside a closed space without air circulation, mold and mildew instantly develop, which are then extremely difficult to remove. The doors should be fixed in the ajar position by 5-10 centimeters. To do this, you can use a soft cloth or a special fastener, if provided by the design.
Pack the equipment in plastic or original packaging, but not hermetically - there must be air access. The storage place should be dry and protected from direct sunlight, since ultraviolet radiation destroys plastic and painted metal surfaces.
Frequently asked questions (FAQ)
How long should you keep the Atlant refrigerator turned off after defrosting before turning it on?
The minimum waiting time is 15-30 minutes. This is necessary to equalize the pressure in the system and drain oil into the compressor if verticality has been disrupted. If the refrigerator was simply defrosted without moving, it is enough to wait until the internal chambers are completely dry.
Is it possible to defrost an Atlant freezer with a hair dryer?
Using a hair dryer is permissible only at a minimum temperature and from a long distance, directing the air flow exclusively to the ice, and not to plastic parts or rubber seals. However, manufacturers do not recommend this method due to the risk of local overheating and deformation of the plastic of the evaporator.
What to do if the refrigerator does not freeze after defrosting?
Check whether the doors are tightly closed and whether the power indicator is on. Let the equipment work without load for 3-4 hours. If the cold does not appear, and the compressor runs constantly or does not start at all, the sensor may have been damaged during cleaning or an electronics failure has occurred - in this case, a call to the technician is required.
Do you need to lubricate the seals after washing?
Yes, it is recommended to do this 1-2 times a year. Use special silicone grease or glycerin. This will preserve the elasticity of the rubber, ensure a tight fit of the door and prevent cracking of the material.
Is it dangerous to defrost a refrigerator on the balcony in winter?
Yes, it is dangerous. Sudden temperature changes can lead to microcracks in metal and plastic. In addition, at low temperatures, the oil in the compressor thickens, and starting after such a “rest” may be difficult. Defrost appliances only at room temperature.
