3. Maintenance

WARNING! Perform maintenance operations only when the product is
switched off and disconnected from power sources.
Isotherm Built-In products are equipped with closed cooling systems, which do not
require maintenance or refrigerant refills.

3.1 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 product should always be defrosted when the layer of frost on the evaporator
reaches a thickness of 3-4 mm or more.
Switch off the product by turning the thermostat knob.
Defrosting should be performed when the products can remain as cool as possible
outside of the product compartment. Do not use sharp objects to remove ice and frost
from the evaporator, as this could damage it and result in leaks.
Only turn product back on once it has been defrosted, cleaned and thoroughly dried.
Some models are equipped with a hole at the base of the inside drawer to facilitate
condensate discharge. A towel can be placed at the base of the product during the
defrosting procedure in order to facilitate water collection.

3.2 Seasonal Maintenance

Seasonal maintenance is performed:
1st with cleaning of the condensing unit. In particular, it is necessary to brush/vacuum
out all the dust that has accumulated. This can be done using a soft brush and a vacuum
cleaner.
2nd with cleaning of the internal compartment. In particular, wash with warm water
and mild soap, drying any water/condensation that may be encountered.
