Maintenance method of idle freezer
1. Unplug the power plug of the freezer and take out all the items stored in the freezer. Wait for the frost to melt. Be careful not to use sharp tools when defrosting. After defrosting, wipe the freezer with a clean rag from the inside to the outside. Do not leave any water in the freezer.
At the same time, it should be noted that the condenser and compressor must not be washed with water, so as not to reduce the insulation performance of the electrical appliance.
2. If the freezer is not used for a long time, the door seal should be padded with paper or other things to prevent the door seal from sticking to the box. At the same time, apply some lime powder on the door seal to prevent sticking.
3. Set the thermostat to “0” or “stop” or “Max” (strong cold point) to keep the thermostat in its natural state and prolong its service life.
4. The freezer should be placed in a ventilated and dry place to avoid direct sunlight. When moving, it should be moved upright and parallel, and should not be tilted to prevent the compressor from falling out of the cylinder.
5. If possible, it is best to power up the idle freezer once a month, let the compressor run normally for half an hour to an hour and then turn it off, and let the compressor run from time to time to prevent the machine from aging.
In winter, idle freezers can be maintained by the above methods. Don’t stop maintenance of the freezer just because the freezer is out of use.
The performance of the freezer can only be optimized by paying attention to it. When using the freezer equipment, the merchants will base on the specific situation of the store. To adjust the number of refrigerators used, due to some special reasons or seasonal factors, some refrigerators will be idle for a long time.
However, this approach may cause a lot of inconvenience to the merchant: “It is clear that the refrigerator is new and has not been used for a long time. When it is idle for a period of time and then put back into use, a problem suddenly occurs. It’s broken, and the friends who bought it at the same time have been using it without any problems.”
In fact, this situation is probably caused by improper operation when the freezer has not been used for a long time and is used again. , I would like to remind everyone that when the freezer that has not been used for a long time is used again, please do the corresponding inspection and cleaning work.
Precautions for re-use of the freezer
So, what harm may the freezer cause if it is not used for a long time, and what should be paid attention to when it is used again?
1. Possible hidden dangers after long-term shutdown
Long-term shutdown may cause the lubricating oil in the compressor to sink to the bottom and become sticky, and all working parts in the machine are in dry state. If no treatment is done at this time, and the compressor is turned on blindly, the piston of the compressor will work without lubrication, which will affect the service life of the compressor and cause economic losses.
2. How to start after long-term shutdown
Therefore, when the freezer that has been disabled in winter is restored to use, it is best to place the freezer in a room with a higher room temperature and plug in the power supply. Stop and start the compressor for a while, then unplug the power plug, and plug it back in after a while (usually 5 to 10 minutes). After repeating this for 2 to 3 times, the lubricating oil in the compressor can be sprayed on each moving part, so that they can be lubricated enough, and then the freezer can officially enter the normal working stage.
In this way, the compressor cylinder block and other moving parts can be prevented from excessive wear due to lack of oil, and the refrigerator can enter the normal working state more smoothly.
It is recommended that after the initial start-up, if you encounter abnormal noise or shutdown, failure to cool down, electricity leakage, etc., you should ask the professionals of regular enterprises to repair, do not disassemble and repair by yourself, so as not to expand the scope of the fault.
It is best to use a refrigerator, arrange a separate power line and use a dedicated socket, and cannot share the same socket with other electrical appliances, otherwise it will cause bad accidents. After the grounding device is installed and the above conditions are met, the refrigerator can be energized.
