Suggestion of using the appliance
please store different foods according to the compartments or target storage
temperature of your purchased products.
If the refrigerating appliance is left empty for long periods, switch off, defrost,
clean, dry, and leave the door open to prevent mould developing within the
appliance.
Food needs to be packed in bags before putting into the refrigerator, and
liquids need to be packed in bottles or capped containers to avoid the problem
that the product design structure is not easy to clean.
