Automatic overheating safety device
To prevent damage and reduce safety risks the
overheating safety device switches off the fan
motor if it becomes too hot.
To indicate that the appliance is still in switched-
on position and connected to the mains, the pilot
light will remain on.
If this happens:
- Set the speed selector to position O (= Off).
- Remove the mains plug from the wall socket.
(The pilot light goes out.)
- Wait for the motor to cool down (approx.
15 minutes).
- Open the appliance. Check that the filters are
not blocked and that nothing is obstructing the
airflow.
- Check that the Rota filter can rotate freely if
moved by hand (fig. 20).
- Close the appliance. Put the mains plug back
into the wall socket and switch on.
If the automatic overheating device is activated
repeatedly, it is advisable to take the appliance to
your dealer for technical inspection.
