23MaintenanceDefrostingBleeding part of the moisture of cooling chambers in form of frost and icegoes with the operation of the applince.Thick frost and ice has an insulating effect, so it reduces cooling efficiency asthe temperetaure increases in the cooling chambers, they need more energy.At this type of appliance defrosting the cooling surface of the refrigerator isautomatic without any external intervention. The termostatic control inter-rupts the operation of compressor at regular intervals for more or less time -during this cooling is interrupted - the temperature of the cooling surfacegoes above 0°C due to interior heating load of the compartment, so defrost-ing occurs. When the surface temperature of the cooling surface has reached+3 - +4°C the thermostatic control restarts operation of the system.Melting water flows through defrost water outlet leaded through the backinto the evaporator tray maintained on the top of compressor and evaporatesdue to its warmth.Check and clean the outlet of meltingwater coming during defrosting regu-larly - a label inside the appliancewarns you for this. If it is clogged themelting water gathered can causeearlier failure as it can go to the insu-lating of the appliance.Clean the melting water outlet with thesupplied pipe scraper that can be seenin the figure. The pipe scraper has to bestored in the outlet.The most typical case of clogging up inthe melting water outlet when you putfood wrapped in some paper into theappliance and this paper contacts back plate of the refrigerator and freezesto it. If you remove the food right at this moment the paper will tear and itcan cause clogging up in the outlet by getting into it.So you are asked to be careful - because of the above - when placing foodswrapped in paper into the appliance.In case of increased demand e. g. during heatwawes, the refrigerator tem-porarily happens to operate constantly - during this the automatic defrost-ing does not work.Remaining small ice and frost stains on back plate of the refrigerator afterdefrosting period is not abnormal.Defrosting of the freezer is automatic in this model.
