II. White mist comes out of a unit
• When humidity is high during cooling operation.
(In oily or dusty places)

the temperature distribution inside a room becomes
uneven. It is necessary to clean the inside of the indoor
unit. Ask your Daikin dealer for details on cleaning the unit.

OPERATION after DEFROST OPERATION.
Moisture generated by DEFROST becomes steam and

This sound is generated by the temperature regulator
working. It will quiet down after about a minute.

indoor units.

immediately after the stop of operation or which is
heard at the start or immediatly after the stop of
DEFROST OPERATION.
