2.3 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, cleaned and
thoroughly dried. A towel can be placed at the base of the refrigerator during the
defrosting procedure in order to facilitate water collection.
3. Maintenance
Isotherm Drawer refrigerators are equipped with closed cooling systems, which do
not require maintenance or refrigerant refills.
The compressor is specifically designed for mobile applications and guarantees
maximum performance and durability. In the winter, the refrigerator must be stored
inside the vehicle, but the compressor will not work at temperatures near or below
0°C. Seasonal maintenance is limited to the cleaning of the condensing unit behind
the refrigerator. In particular, it is necessary to brush/vacuum out all the dust that
has accumulated due to the fan. This can be done using a soft brush and a vacuum
cleaner. It is important to keep the inside of the refrigerator clean by washing it
with warm water and mild soap and by drying any water/condensation that may be
encountered.
To keep the surface of the door in good conditions and intact, make sure that it is
always dry and clean.
In order to prevent damage to the electrical/mechanical components and/or the
formation of mould, when shutting off the refrigerator for extended periods of
