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.

Defrosting 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.
