The appliance and environment

This appliance does not contain gasses which could
damage the ozone layer, in either its refrigerant circuit or
insulation materials. The appliance shall not be discarded
together with the urban refuse and rubbish. Avoid damag-
ing the cooling unit, especially at the rear near the heat
exchanger. Information on your local disposal sites may
be obtained from your municipal authorities.
The materials used on this appliance marked with the
sympol are recyclable.

Maintenance

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 interven-
tion. 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 plate goes above 0 °C due to interior heating load
of the compartment, so defrosting occurs. When the sur-
face 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
earlier failure as it can go to the insulating of the
appliance.
defrosting regularly
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 refrig-
erator 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 heat-
waves, the refrigerator temporarily happens to oper-
ate constantly. During this the automatic defrosting is inef-
fective.
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 defrost-
ing 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
possibly cool place or replace them into another refriger-
ator.
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:
