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.
This appliance automatically defrosts the cooling
surface of the refrigerator 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.
Defrost water flows through the 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 defrost water outlet
regularly - a label inside the appliance
warns about for this. If it is blocked the water
gathered can cause damage to the insulation of
the appliance.
Clean the defrost water outlet with the supplied pipe
scraper that can be seen in the figure. The pipe
scraper has to be stored in the outlet.
Extra care should be taken when putting items,
especially foods wrapped in paper, in the appliance.
Blockages to the defrost water outlet often occurs
when wrapped foods are placed in the back of the
refrigerator, and the wrapping contacts the back plate
of the fridge and sticks to it.
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 normal.
When small frost and ice forms scrape off and remove
frost and ice coating with the supplied plastic scraper.
When the 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 (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 refrigerator.
