17When refrigerator is first used or at starting, it canproduce stronger drones because its running is notsteady, and the sound shall become smaller, asrunning stabilizes.The sound produced at compressor working, andthe tap-tap sound when compressor starts orcloses: all these are normal.When refrigerator is used for the first time, or whenin starting, it can give out bigger sound becausethe appliance is not in steady running state. Thesound shall become diminished as its runningbecomes steady.When liquid refrigerant flows in evaporator, it canproduce the sound similar to water flowing. Thiskind of sound usually occurs at the evaporator andcompressor parts: when refrigerator stops working,the liquid refrigerant flow back, it shall also producethe continuous or interrupted "gurgling waterflowing" sound.Question answeringSometimes, the appliance housing gets hot,especially for the first use after switching it on. Butthis is not a defect, it is just designed for preventingdew, rust, and for energy saving. It is normal.When carrying out the defrosting cycle, the waterfallen down on heating element can give out thesound of "hiss" or "tittering". At the end of defrosting,it is possible to produce slight "crackling". At thesame time, evaporator can produce the sound of"boiling" or "gurgling". This is normal state causedby defrosting.hissitteringboilingDaDaboiling16Stop usageLeave for holiday* If the holiday is for a short time, take out those foodthat are susceptible to be deteriorated, set propertemperature position, determine whetherrefrigerator doors have been closed well.* If you are to be out for a long time holiday, it isnecessary to disconnect the power supply of therefrigerator, take out food, and clean the interiorafter melting frost inside, open refrigerator doorsafter wiping, to prevent small food remainsproducing bad smell.When moving* Pull out power plug, to disconnect power supply* Take out all food from the refrigerator* Use adhesive tapes to fix movable parts such asshelves in the refrigerator compartment, humiditymaintaining box, and freezer drawers* Close well refrigerator doors, and fix them withadhesive tapes, so as to prevent its openingduring movement* During moving refrigerator, maximum angle of tiltshall not exceed 45°(the angle with the verticaldirection) to avoid causing damage to refrigerationsystem, and influencing normal usage.Note: In no case,should the refrigerator be placed flat.
