FAULT-FINDING
Mist and humidity are not produced:
Check that the power indicator is illuminated. If not, check
that the mains plug is fully inserted into the mains socket and
that the mains socket is functional.
Check that the mode is not switched to Mode II or Mode III
(which have periods when no mist is produced)
Check that the water tank is correctly installed, and that the
spring-plunger in the filling cap moves freely when pressed.
A stream of air is produced, but no humidity:
If there is still no humidity produced, remove the water tank,
and empty any water from the main body of the unit. Replace
the water tank and try again.
If this does not solve the problem, clean the transducer as
described in the "Maintenance" section.
Mist has a bad smell:
Clean the tank, and the transducer as described in the
"maintenance" section.
