2.3 Standard model defrosting

Since the evaporator operates at temperatures well below freezing, ice and frost will
inevitably form upon it.
The humidity in the air, the temperature and the number of times the door is opened
will have a significant impact on frost formation.
The refrigerator should always be defrosted when the layer of frost on the
evaporator reaches a thickness of 3-4 mm or more.
Turn off the refrigerator by turning the thermostat to its 0 position.
Defrosting should be performed when the products can remain as cool as possible
outside of the refrigerator itself. Do not use sharp objects to remove ice and frost
from the evaporator, as this could damage it and result in leaks.
Only turn the refrigerator back on once it has been defrosted (not including Frost
Free models), cleaned and thoroughly dried. Remove, empty and dry the drip tray
beneath the evaporator. A towel can be placed at the base of the refrigerator during
the defrosting procedure in order to facilitate water collection.

2.4 No-Frost model defrosting

In No-Frost models, defrosting is performed fully automatically with times defined by
the manufacturer.
The No-Frost system is composed of a fan which forces air circulation inside the
trunk. The humidity inside the unit is deposited on the evaporator unit, creating
a thickness of frost that is automatically eliminated during the defrost cycle. The
condensation caused by defrosting is conveyed outside the trunk and made to
evaporate by means of a natural heating system of the condensing unit/compressor.
