Cleaning the heat exchanger
Check the heat exchanger unit form
time to time and clean it if
necessary. A Maintenance message
will remind you. You can decide
after how many hours you want the
message to appear.
Setting the correct option will depend
on how much link and dust has
accumulated.
Select a more appropriate option if you
find that the heat exchanger is very
dirty or not very dirty at the end of the
set time.
The machine is delivered with this
option set to 400 hours.

In addition to the drying levels, the
residual moisture as a % can be
