Defrosting

Bleeding part of the moisture of cooling chambers in
form of frost and ice goes with the operation of the
appliance.
Thick frost and ice has an insulating effect, so it
reduces cooling efficiency as the temperature
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 thermostatic control interrupts 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
defrosting 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 regularly -
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 insulating
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
heatwaves, the refrigerator temporarily happens
to operate constantly - during this the automatic
defrosting does not work.
Remaining small ice and frost stains on back plate of
the refrigerator after defrosting period is not abnormal.
The freezer can not be equipped with automatic
defrosting set since the deep-frozen and frozen foods
do not endure melting temperature.
When small frost and ice occurs scrape off and
remove frost and ice coating with the supplied plastic
scraper.
When ice coating is so thick that it cannot be removed
with the plastic scraper, the cooling gill have to be
defrosted. Frequency of defrosting depends on usage
