Refrigeration equipment Pozis has proven itself to be a reliable and durable equipment that can operate for years without serious failures. However, even the most modern models require periodic maintenance, in particular, complete defrosting of the freezer. Many owners are wondering how to safely perform this procedure without damaging the compressor and cooling system. The shutdown process is not complicated, but requires adherence to a clear algorithm of actions to maintain the functionality of the unit.
First of all, you need to understand that forced shutdown devices from the mains should be done only after removing the products. This is a basic safety rule that is often ignored in a hurry. If you plan to simply turn off the appliance during the holidays, the procedure will be different from that required for a major defrost. In both cases, it is important to act consistently to avoid unpleasant odors, leaks or damage to electronics.
In this article we will analyze in detail all the stages of preparation, the shutdown process itself and the subsequent startup of the equipment. We will look at the nuances of working with various models, including those equipped with the No Frost or Low Frostsystem. We will also pay attention to issues related to transportation and long-term storage of equipment in a switched off state. The right approach will extend the life of your refrigerator and maintain food freshness.
Preparatory stage before turning off
The procedure should begin long before your hand reaches for the fork or temperature regulator. The first step is always to clear the interior space of perishables. If you plan to defrost, the food must either be eaten or transferred to another cold place, for example, in a thermal bag with ice or to a neighbor. For equipment with a system complete defrosting this is critically important, since the process can take from 10 to 24 hours.
After the chambers are released, it is necessary to remove all removable elements: shelves, drawers, egg trays and containers on the door. Plastic parts can become brittle due to sudden changes in temperature, so it is better to wash them separately at room temperature. In addition, removing the shelves will provide better air access to the interior walls, which will speed up the melting of the ice. It is also better to remove the glass shelves to avoid the risk of damage from falling pieces of ice.
⚠️ Attention: Never try to speed up the ice melting process by using a hairdryer, fan heater, or, especially, sharp objects like a knife. Mechanical damage to the evaporator located behind the rear wall will lead to a refrigerant leak and costly repairs, which are often not economically feasible.
It is also important to prepare the area around the refrigerator. Cover the floor with absorbent rags or put down rags, since when the “fur coat” melts, a significant amount of water is formed. Make sure that there is easy access to an outlet nearby and that the doors can be opened wide without obstruction. If the room is hot, you can open the windows to create a draft, but do not direct the flow of hot air directly onto the plastic seals.
Algorithm for properly disconnecting from the network
The very moment of disconnecting from electricity seems trivial, but there are technical nuances here too. First you need to set the thermostat to the “0” or “Off” position. This action signals the electronics or mechanical relay to stop the cooling cycle. Suddenly pulling the plug from the socket while the compressor is running can cause a voltage surge and unwanted load on the engine start relay.
After moving the regulator to the zero position, wait 2-3 minutes. During this time, the refrigerant in the system will have time to distribute and the pressure will equalize. Only after this pause can you remove the plug from the socket. If the refrigerator model is Pozis equipped with electronic control, wait until the indicators on the display go out completely. Some modern models have built-in protection, but compliance with this rule is a sign of proper operation.
If you plan long-term storage or transportation, it is better to fix the plug on the body or put it in a bag with documents so that it does not get lost. For models with the system Drip defrosting immediately after switching off, you need to open the doors and lock them in the open position. This will prevent the appearance of a musty smell and mold inside the chambers during idle time.
☑️ Checklist before turning off
The compressor takes time (usually 10-15 minutes) to restore pressure in the system. If you turn on the unit earlier, the engine may burn out or go into protection. This interval is necessary for correct operation refrigerant and lubrication of the rubbing parts of the compressor.
Features of defrosting various Pozis models
Equipment Pozis is available in various modifications, and the maintenance process may vary. The main difference lies in the cooling system: drip, low-temperature (Low Frost) or full No Frost. Understanding your model type will help you avoid mistakes. For example, in refrigerators with drip system ("crying wall"), ice periodically freezes on the back wall of the main chamber, which melts during pauses in the compressor.
Freezers in such models, as a rule, require manual defrosting. Ice is constantly growing here, and ignoring this leads to increased energy consumption and reduced freezing efficiency. In models with a system Low Frost ice forms much more slowly due to the special design of the evaporator and air circulation, but periodic defrosting is still necessary, usually 1-2 times a year.
| System type | Frequency of defrosting | Does it need to be drained water | Features |
|---|---|---|---|
| Drip (Main) | Automatic | No (through the groove) | Only for the refrigerator compartment |
| Manual (Freezer) | 1-2 times a year | Yes, manually | Requires complete shutdown |
| No Frost | As needed (cleaning) | No | Defrosting only for sanitation |
| Low Frost | once a year | Yes, a little | Less ice than manual |
For models with a system No Frost the concept of “defrosting” transforms into “spring cleaning”. Ice does not freeze in them due to the constant circulation of dry air, but dust and bacteria can accumulate on the evaporator, which is hidden behind a plastic panel. It is also recommended to turn off such units once a year for thorough washing and disinfection of internal surfaces.
What to do if the ice does not melt?
If after 12-15 hours of natural thawing an ice crust remains, you can speed up the process by placing bowls of hot (not boiling water!) water inside the chambers. Close the door for 10-15 minutes, then repeat. This will safely soften the ice without the risk of damaging the plastic.
Care for internal chambers and seals
The period when the refrigerator is turned off and empty is the ideal time to carry out hygiene procedures. Invisible bacteria can accumulate inside, causing unpleasant odors. To clean, use a weak solution of baking soda or a special household appliance cleaner. Aggressive chemicals, abrasive powders and solvents can damage the plastic coating of the chambers and make it cloudy.
Particular attention should be paid to the rubber seal on the doors. It is in its folds that mold most often settles. Wipe the seal with a soft cloth soaked in vinegar or hydrogen peroxide. If the rubber has lost its elasticity and begins to crumble, it must be replaced, otherwise the refrigerator will no longer maintain the temperature and the compressor will work without interruption.
After washing, all surfaces must be wiped dry with a clean rag. Remaining moisture may cause condensation to form when first turned on. Refrigerator doors Pozis must remain open until all hard-to-reach places are completely dry. This usually takes several hours. Do not rush to put food in immediately after switching on.
⚠️ Attention: When cleaning the drainage hole (usually located at the bottom of the rear wall of the refrigerator), use a special flexible brush or a cotton swab. Do not pierce the channel with a hard wire, so as not to damage the internal water drainage tube, the restoration of which will require disassembling the case.
Actions during long-term downtime or transportation
If you leave for the country for the winter or move, the operating rules change. A refrigerator Pozisleft on unattended can cause a fire in the event of a power surge or faulty wiring. Therefore, in case of prolonged absence, the equipment must be turned off. However, simply unplugging the cord is not enough - you need to prepare the unit for “sleep mode.”
After thorough defrosting and washing, the refrigerator doors should not be closed tightly. They need to be fixed in the slightly open position. To do this, you can use a piece of foam rubber, a rolled up towel, or special shipping tape placed between the body and the door. This will ensure air circulation and prevent the appearance of musty odors and mold inside the enclosed space.
When transporting, it is important to maintain a vertical position. The refrigerator Pozis can be tilted no more than 40 degrees. If it is placed on its side, oil from the compressor may leak into the refrigerant circuit. When turned on again, this will cause oil shock, which can damage the compressor. If transportation on its side was unavoidable, before turning on the unit must stand upright for at least 24 hours.
First start after defrosting or downtime
Starting the refrigerator after a long period of inactivity or defrosting is a crucial moment. Make sure that the unit is installed level, with a slight tilt to the rear, so that the doors close automatically under the influence of gravity. Check that nothing is preventing the seal from sealing tightly. Plug in the device and set the thermostat to the middle position. Do not load food immediately.
Idling should last at least 2-3 hours, but it is better to leave the refrigerator empty overnight. During this time, it will reach the required temperature, and the automation will turn off the compressor. Only after the first “on-off” cycle can you start loading products. This is especially important for models with electronic controlthat need time to calibrate sensors.
If after turning on you hear unusual sounds (gurgling, loud knocking) or the refrigerator does not freeze for 5-6 hours, you need to contact a service center. It is possible that components have shifted or freon has leaked during defrosting or transportation. Normal operation is accompanied by a quiet hum of the compressor and rare clicks of the relay.
How long should the refrigerator dry after washing?
To completely evaporate moisture from hard-to-reach places, including the drainage system and the space behind the plastic panels, it is recommended to dry the refrigerator with the doors open for at least 4-6 hours. If wet cleaning was carried out with a large amount of water, it is better to leave it overnight.
Is it possible to use a vacuum cleaner to remove ice?
You can use a household vacuum cleaner to remove ice, but only in the blowing mode (if there is such a function) with warm air. It is strictly forbidden to suck up moisture and pieces of ice with a regular vacuum cleaner - this will lead to damage to the vacuum cleaner motor. However, it is safer to let the ice melt naturally.
What to do if an unpleasant odor appears after turning it on?
An unpleasant odor may indicate bacteria or oil getting into the system (if the refrigerator was lying down). Wipe the chambers with citric acid solution or activated carbon. If the smell is chemical or burning, immediately turn off the device and call a technician.
Do the door hinges need to be lubricated?
Yes, if you notice that the door has become difficult to open or creaks. Use safe silicone oil or special grease for refrigerators. Do not use edible oils (sunflower, olive), as they oxidize over time, thicken and begin to smell unpleasant.
