Maintenance
Unplug the appliance before carry-
ing out any maintenance opera-
tion.
Warning
This appliance contains hydrocarbons in its
cooling unit maintenance and recharging
must therefore only be carried out by autho-
rised technicians.
Defrosting
Bleeding part of the moisture of cooling
chamber in form of frost and ice goes with
the operation of the refrigerator.
Thick frost and ice has an insulating effect,
so it reduces cooling efficiency as the tem-
perature increases and it needs more ener-
gy.
At this type of appliance defrosting cooling
compartment is automatic without any exter-
nal intervention.
The thermostatic control interrupts the opera-
tion of compressor at regular intervals for
more or less time - during this cooling is
interrupted - temperature of the cooling com-
partment increases and defrosting occurs.
After defrosting the thermostatic control
restarts operation of the system.
Melting water flows through defrost water
outlet into the evaporative tray maintained on
the top of compressor and evaporates due to
warmth of it.
Check and clean the outlet of
melting water coming during
defrosting regularly. If it is
clogged the melting water gath-
ered can cause earlier failure as it
can go to the insulating of the
appliance.
Clean the melting water outlet with the sup-
plied pipe scraper that can be seen in the fig-
ure. The pipe scraper has to be stored in the
outlet.
Occasionally check the defrost water outlet
not to be clogged up.
The most typical case of clogging up in the
defrost water outlet when you put food
wrapped in some paper into the appliance
and this paper contacts back plate of cooling
compartment 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. dur-
ing heatwaves, the refrigerator tem-
porarily happens to operate constant-
ly - during this the automatic defrost-
ing is ineffective.
Remaining small ice and frost stains on back
plate of the cooling compartment after
defrosting period is not abnormal.
Cleaning
Never use metal objects for clean-
ing your appliance as it may get
damaged.
NEVER use detergents, abrasive powders,
highly perfumed cleaning products or wax
polishes to clean the interior as these will
damage the surface and leave a strong
odour.
