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 and they need more energy.
At this type of appliance defrosting the cooling plate of the
refrigerator is automatic without any external intervention.
The thermostatic control interrupts the operation of com-
pressor at regular intervals for more or less time - during
this cooling is interrupted - the temperature of the cooling
plate goes above 0 °C due to interior heating load of the
compartment, so defrosting occurs. When the surface
temperature of the cooling plate 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 evaporative tray maintained on
the top of compressor and evaporates due to its warmth.
Check and clean the outlet of melting water
coming during
- a label inside the appliance warns you for this. If it is
clogged the melting water gathered can cause earli-
er failure as it can go to the insulating of the appli-
ance.
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
defrosting regularly
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 heat-
waves, the refrigerator temporarily happens to
operate constantly. During this the automatic defrosting is
ineffective.
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.
The tray in figure is not a piece of accessories to the appli-
ance!
When ice coating is so thick that it cannot be removed with
the plastic scraper, the cooling plate has to be defrosted.
Frequency of defrosting depends on usage (generally 2-3
times a year).
Take the frozen foods out of the appliance, and put them
into a basket lined with paper or cloth. Store them in a pos-
sibly cool place or replace them into another refrigerator.
Pull out the mains plug from the mains socket, so both
parts of the appliance are out of operation.
Open the doors of both parts of the appliance and clean
the refrigerator according to 'Regular cleaning'. Maintain
and clean the freezer as following:
Sweep the melting water with a cloth or sponge off the
cooling plate. The melting water swept down gathers in the
bottom of the appliance and can be removed with a hygro-
scopic cloth or a sponge.
Wipe the surfaces after defrosting.
