Cause (This is normal)
It is the sound of the motor that moves the fl ap.
It is because of the rotation of the fan.
This is the sound of the unit changing the rotational speed of the
motor.
Cause (This is normal)
The unit's parts have a smell when it is fi rst used.
Or the deodorizing performance of the deodorizing fi lter has de-
creased.
Clean the deodorizing fi lter. (P.E-27)
The unit's interior is lined with control circuits.
This causes the unit to become warm.
Cause (This is normal)
It may have become misaligned when it was moved by hand. If it
does not work properly because it was moved by hand, stop it by
touching the "Power" button once, and start the operation again.
The fan may stop
if it is set in eco saving operation.
The rotation gradually increases.
It takes approximately 1 minute for the rotation to increase.
Separate the purifi er from the television and radio, or change the
orientation of the purifi er.
Or, use an outlet in a different location.
