During this operation use the following personal safety measures:
- safety glasses
- respiratory protection mask
- gloves
5.3 Cleaning of the condenser
The condenser is a heat exchanger hence if it is dirty or clogged the air cannot pass freely into the
same, it cannot do its job properly and the efficiency of the refrigeration system falls down
proportionally. FOR THOSE REASONS IT IS IMPORTANT TO KEEP CLEAN THE CONDENSER
WHERE TYPICALLY IT MEANS TO CLEAN IT MONTHLY.
WARNING!!!
Always switch off the unit and disconnect power cord before cleaning, it is dangerous to do it
with power: fan may start suddenly at any time!
According to the model, compressor can be placed on top or at the bottom of the appliance.
Compressor on top
Use a convenient ladder to reach the condenser. Use an air jet or an aspirator with a soft dry brush if
necessary (Fig. 21) and remove any dust or fluff from the heat exchanger fins.
After cleaning, start the appliance.

5.4 Precautions for prolonged disuse
If the refrigerator should remain unused for more than 15 days please proceed as follows:
switch off the appliance and disconnect the power cord
clean the interior of the cabinet, shelves, trays, runners and supports, paying special attention to
critical areas such as articulations and magnetic sealing strips
leave doors slightly open to prevent accumulation of residual humidity
