clean the filters
using a vacuum cleaner; it is preferable
to replace the filters after a few cleanings and in any
case at least once a year;
reinstall the filters
(fig.33,34,35);
In case of prolonged inactivity of the appliance we
recommend removing the filters, to prevent the risk of
being damaged, due to the possible formation of
condensation.
Heat exchanger
The heat exchanger does not usually require regular
cleaning. The frequency of cleaning is determined by
the level of air pollution (in input and output from the
home) and the state of efficiency of the filters.
The heat exchanger should in any case be replaced
every 6 years, even if the filters have been subjected to
regular maintenance.
To access the exchanger follow the instructions below:
disconnect the appliance
from the mains power
supply;
