Purchasing new household equipment is always an event that requires a careful approach, especially when it comes to large-sized equipment. Correct initial activation of the model Atlant 4421 directly affects the service life of the compressor and the quality of freezing products in the future. Many owners make the mistake of believing that simply plugging the cord into an outlet is enough, but ignoring the rules of transportation and temperature adaptation can lead to refrigerant failure or failure of the electronics.
The startup process includes several critical steps: from checking the integrity of the case after delivery to setting the optimal temperature conditions. Particular attention should be paid to the settling time required for the compressor oil to drain. If you skip this stage, the unit may operate with increased noise or may not start at all, which will require expensive repairs.
In this article we will analyze in detail the algorithm of actions for the model Atlant XM 4421so that you can safely and efficiently start operating your equipment. Compliance with all recommendations will allow you to avoid typical mistakes and ensure stable operation of the device for many years without the need to call a technician.
Checking the equipment after transportation
Before connecting the device to the electrical network, it is necessary to conduct a thorough external inspection. Even if delivery went smoothly, hidden defects may only become apparent upon careful examination. Make sure that there are no dents, scratches or chips on the case that could disrupt the tightness of the thermal insulation. Atlant 4421 there are no dents, scratches or chips that could disrupt the tightness of the thermal insulation.
Check the integrity of the seals on the doors of the refrigerator and freezer compartments. The elastic band should fit snugly around the entire perimeter, without cracks or creases. If the door does not fit tightly, the cold will escape, forcing the compressor to work in increased mode, which will significantly reduce its resource.
⚠️ Attention: If during inspection, mechanical damage to the housing or a violation of the door geometry is detected, do not turn on the device. Contact the store or delivery service to file a claim, since the operation of a damaged unit does not guarantee the safety of the products.
Remove all shipping elements, which inexperienced users often forget to remove. The chambers may contain foam pads, tape, or silica gel packs. Also check the presence and position of the internal shelves and trays - they must be securely fixed in their grooves.
Rules for standing before turning on
One of the most important questions that worries buyers: how long should the refrigerator stand Atlant 4421 before turning on. The answer depends on the position in which the transport was carried out. During transportation, oil from the compressor may have entered the refrigerant circuit, and it needs time to return to its original position.
If the device was transported in a vertical position, the minimum settling time is 2-3 hours. This is enough to stabilize the internal pressure and settle the vibration that occurs during vehicle movement. However, if possible, it is better to wait 4 hours to be completely sure.
The situation changes dramatically if Atlant 4421 was transported lying down. In this case, the oil is guaranteed to flow into the evaporator tubes. The minimum waiting time in this case increases to 8–10 hours, and in the cold season it is better to wait a day. An attempt to start the compressor ahead of time will lead to water hammer - a condition when incompressible oil enters the cylinder of a working piston.
Do not rush things. Prolonged downtime of the device will not harm it, while premature startup can be fatal to the cooling system. Remember that the compressor is the heart of your refrigerator, and its replacement is often comparable in cost to the price of a new unit.
Preparation for the first start
After the settling time has expired, it is necessary to properly prepare the internal space. Before loading the chambers for the first time with products, Atlant 4421 you need to wash them thoroughly. Use a weak solution of baking soda or a mild detergent without aggressive abrasives or strong odors.
Wipe all shelves, drawers and interior walls with a damp cloth, and then wipe them dry with a clean cloth. This will remove production dust and possible packaging odors. Pay special attention to the ventilation holes on the back wall - they must be free for normal air circulation.
| Parameter | Standard value | Permissible deviation |
|---|---|---|
| Main voltage | 220–230 V | ±10% |
| Current frequency | 50 Hz | ±1 Hz |
| Minimum distance to the wall | 5 cm | At least 3 cm |
| Operating time before loading | 2 hours | 1.5–3 hours |
Install the refrigerator on a flat surface. Use a building level to check levelness. Height adjustment is made using the front support legs, which can be twisted or unscrewed. Correct installation will prevent the appearance of vibration and excess noise during compressor operation.
☑️ Preparation for the first start-up
The process of first connection to the network
When all the preparatory stages have been completed, you can proceed to the actual connection. Plug the power cord into a separate grounded outlet. It is not recommended to use extension cords or tees, as the starting currents of the compressor can be high, and weak contact will lead to heating and melting of the wires.
After connecting to the network Atlant 4421 it will not begin to cool instantly. Modern models are often equipped with a protection system that blocks the compressor from starting for several minutes to equalize the pressure in the system. You may hear a quiet click or hum - this is normal operation of the automation.
The indicator lights on the front panel should light up. If the model is equipped with electronic control, the display will show the current temperature readings. In mechanical models, the green network indicator will light up. If the indicators do not light, check for voltage in the outlet.
⚠️ Attention: During the first hours of operation, the refrigerator may make sounds of gurgling or liquid flowing. This is normal - the refrigerant begins to circulate through the system. However, loud knocking or grinding noises require immediate shutdown and inspection.
Leave the empty refrigerator running for 2 to 3 hours. During this time, it will reach the required temperature, and the automation will turn off the compressor. Only after the first cooling cycle can you start loading products. Sharp loading with warm products will cause the motor to wear out.
Setting temperature modes
The model Atlant 4421 can be equipped with both mechanical and electronic controls. If you have a mechanical version, there is a thermostat inside the refrigerator compartment with a scale from 1 to 7 (or Min/Max). For the first start, it is recommended to set the regulator to the middle position - usually this value is 3 or 4.
For electronic models, the setting is made through the panel on the case. The optimal temperature for the refrigerator compartment is +4°C, and for the freezer - minus 18°C. You should not immediately set the minimum values, as this will create an excessive load on the unit.
What does the Super Freeze function mean?
The Super Freeze mode forces the compressor to operate continuously to quickly freeze a large volume of products. Do not use this mode constantly, as it significantly increases energy consumption and wear on the compressor.
It is important to distribute the food evenly without blocking the ventilation holes. Cold air should circulate freely inside the chambers. If the shelves are filled to capacity immediately after switching on, the temperature in the center of the chamber may remain high, which will lead to food spoilage.
Typical mistakes when starting up for the first time
Failure to follow the instructions often leads to problems that could be easily avoided. One of the most common mistakes is ignoring the settling time. Users forget that the oil must return to the compressor crankcase, and turn on the device immediately after skidding.
Another mistake is installing the refrigerator close to the wall or in a niche without gaps. Atlant 4421, like any other equipment, requires heat removal from the condenser located at the back or on the sides. Lack of ventilation will lead to overheating and frequent engine starts.
Incorrect initial loading is also common. People put hot pots or large amounts of room temperature food into a refrigerator that has not yet cooled down. This causes a sharp jump in load and the formation of ice, which will then be difficult for the system to cope with.
Why does the Atlant 4421 refrigerator hum loudly after switching on?
Humming can be caused for several reasons: improper installation (shipping bolts not unscrewed or legs not adjusted), touching the pipe body or walls, or the operating characteristics of the compressor. If the noise does not stop after eliminating external factors, diagnostics are required.
How long does it take the refrigerator to reach temperature for the first time?
Usually the primary cooling process takes from 2 to 4 hours depending on the room temperature. Complete freezing of the freezer to -18°C can take up to 10–12 hours of continuous operation.
Can Atlant 4421 be connected to the network via an extension cord?
Manufacturers do not recommend using extension cords, especially cheap or old ones. If you cannot do without them, make sure that the cross-section of the extension cable corresponds to the power of the refrigerator, and that the contacts in the socket are tight. It is better to use a surge protector with protection against power surges.
