Defrosting
Bleeding part of the moisture of cooling chambers in form of frost and ice
goes with the operation of the applince.
Thick frost and ice has an insulating effect, so it reduces cooling efficiency as
the temperetaure increases in the cooling chambers, they need more energy.
At this type of appliance defrosting the cooling surface of the refrigerator is
automatic 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 surface
goes 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 back
into the evaporator tray maintained on the top of compressor and evaporates
due to its warmth.
Check and clean the outlet of melting
water coming during defrosting regu-
larly - a label inside the appliance
warns you for this. If it is clogged the
melting water gathered can cause
earlier failure as it can go to the insu-
lating of the appliance.
Clean the melting water outlet with the
supplied pipe scraper that can be seen
in the figure. The pipe scraper has to be
stored in the outlet.
The most typical case of clogging up in
the melting water outlet when you put
food wrapped in some paper into the
appliance and this paper contacts back plate of the refrigerator and freezes
to it. If you remove the food right at this moment the paper will tear and it
can cause clogging up in the outlet by getting into it.
So you are asked to be careful - because of the above - when placing foods
wrapped 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 after
defrosting period is not abnormal.
Defrosting of the freezer is automatic in this model.
