What is Nano Titanium?


Nano Titanium is a cutting-edge technology that uses a TiO2 catalyst to provide a powerful anti-bacterial and deodorizing effect.Nano Titanium particles are incredibly small (about 5nm). If you imagine the Earth’s diameter is 1 meter, then 5nm would be the size of a golf ball compared to the Earth. The filter is packed with these minute particles to firmly catch and resolve bacteria, which are approximately 1000 times larger, mold and odors.




Why is there water inside the container at the back/bottom side of the refrigerator?


The container at the back/bottom side of the refrigerator is called drain pan or evaporator pan. The water from defrosting process will be collected in it. You can just leave the water there untouched, as the water can evaporate and water level can drop or disappear itself.

Why is the side of the refrigerator body hot?

In order to prevent the refrigerator from sweating and also to ventilate the heat, especially for the new fridge, during the high-speed operation of the compressor or when the doors are opened frequently, a lot of heat is generated and emitted from the side of the fridge body.The temperature can rise quite high, but it does not pose any safety or performance problems, but please avoid touching it.




Why are there water droplets on the outside of the refrigerator?

It is not a malfunction, and the water droplets can be wiped off using a dry cloth and the installation area should be well ventilated.




Why does one door open when the other closes?

The compartments are connected by cold air pathway where the air pressure will lead to the opening of the other door when one door closes hard. This is not malfunction.

freshness of the vegetables.




Why do both crushed and cubes ices dispensed out when I select only crushed ice button?
