that the fan is set to the minimum speed when it is first
switched on and that it is maintained for at least one day.
Failure to carry out the above procedure could
cause, only for the first day of use, a malfunction of
the evaporating panels with consequent outflow
of water drops from the ducts.
In the first few hours after the cooling system is first put
into operation, an unusual smell may be felt, due to the
wetting of the treated cellulose materials that make up
the evaporative panels. The duration of this phenome-
non is however limited to a few hours and the substances
emitted are not harmful in any case.
The fan motor may also emit a particular smell for a short
period of time, caused by the initial heating and residues
of oils or paints on the surface of the motor itself.
