Use

Remember that a newly purchased freezer should not be turned on immediately after placing it in the intended location. You have to wait for at least four hours, and after turning on the freezer, you have to wait a few more hours for the required temperature to be reached, and only then, with small time intervals, can you put in the products to be frozen. For additional information on the use of a particular freezer, see its instruction manual.
The optimal temperature must be set in the freezer -18 ˚C (please also refer to the instructions of the manufacturer in the user manual), as each degree the temperature is decreased increases energy consumption by around 5%.
It is not recommended to fill the freezer compartment but to leave free space for air to circulate.
Wrapping food carefully helps reduce moisture loss and prevent freezer burn.
Try opening the freezer door/lid as rarely as possible and do not leave it open for long periods of time. Otherwise, warm air will enter the freezer, making it necessary to lower the temperature again, which will increase electricity consumption.
It is recommended to turn off the freezer in advance before a storm or expected power outages. This is especially true if it is equipped with an electronic display and buttons as the electronics are most sensitive to power outages. The products in the freezer will stay cold for a while even if it is turned off. Manufacturers state that after turning off the freezers, products will remain frozen for about 24 hours; however, various tests show that this should not be completely relied upon, especially in the case of vertical freezers.
