V. THE AIRFLOW DIRECTION DIFFERS FROM
THE REMOTE CONTROLLER DISPLAY.
• The airflow flaps do not swing when the
remote controller displays the swing opera-
tion.
<HEATING OPERATION>
This is because the airflow direction is controlled
so it is horizontal right after the operation starts
or when the indoor temperature is higher than
the set temperature to prevent air from blowing
directly toward your body.
After a while, the swing operation starts.
(Refer to "MOVEMENT OF THE AIRFLOW
FLAP" on page 7.)
• The airflow direction display of the remote
controller differs from the actual operation of
the airflow flaps.
<COOLING and PROGRAM DRY OPERA-
TIONS>
When the operation in a downward airflow direc-
tion is set, the airflow direction differs from the
display for a period of time to prevent the flaps
from getting frosted.
After a while, the airflow direction changes to the
set direction.
(Refer to "MOVEMENT OF THE AIRFLOW
FLAP" on page 7.)
<HEATING OPERATION>

set direction.
(Refer to "MOVEMENT OF THE AIRFLOW
FLAP" on page 7.)
VI. AIRFLOW FLAPS DO NOT CLOSE.
• The airflow flaps do not close even when
operation stops.
If the air discharge is set downward, to avoid
condensation on the flaps, the flaps once close
and then open again.
After a while they close again.
VII.WHITE MIST COMES OUT OF A UNIT
• When humidity is high during COOLING
OPERATION (In oily or dusty places)
If the inside of an indoor unit is extremely con-
taminated, 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. This oper-
ation requires a qualified service person.
Check the usage environment.

• When the operation is switched to the HEAT-
ING OPERATION during or after the DEFROST
OPERATION.
Moisture generated by defrost becomes steam
and will float around.
When the remote controller display shows
" ", the unit is in DEFROST OPERATION.
VIII.NOISE OF AIR CONDITIONERS
• A ringing sound after the unit starts.
This sound is generated when the motors for
driving the airflow flaps are working.
It will quiet down after about a minute.
• A continuous flow "Shuh" sound is heard
when the systems is in COOLING or
DEFROST OPERATION.
This is the sound of refrigerant gas flowing
through both indoor and outdoor units.
• A "Shuh" sound which is heard at the start or
immediately after the stop of operation or
which is heard at the start or immediately
after the stop of DEFROST OPERATION.
This is the noise of refrigerant caused by flow
stop and flow change.
During HEATING OPERATION, the system
switches to DEFROST OPERATION automati-
cally. The remote controller shows "
After 6 to 8 minutes (maximum 10 minutes), the
system returns to its original operation.
• A continuous flow "Shah" sound is heard
when the system is in COOLING OPERATION
or at a stop.
Moisture removed from the indoor air during the
COOLING OPERATION is drained. (The drain-
ing device is provided as an optional part.)
• A "Pishi-pishi" squeaking sound is heard
when the system is in operation or after the
stop of operation.
Expansion and contraction of plastic parts
caused by temperature change makes this noise.
IX. DUST FROM THE UNITS
• Dust may blow out from the unit after starting
operation from long resting time.
Dust absorbed by the unit blows out.
X. THE UNITS GIVE OFF ODORS
• During operation
The unit absorbs the smell of rooms, furniture,
cigarettes, etc., and then emits them.
If odor is a concern, you can set to zero airflow
rate when the indoor temperature reaches the
set temperature.
For details, contact your Daikin dealer.
