Daikin FVQ71CVEB Operation Manual page 15

• The remote controller displays "
air discharge stops.
This is because the system automatically
switches to DEFROST OPERATION to prevent
a decrease in heating capacity when frost on the
outdoor unit increases.
After 6 to 8 minutes (maximum 10 minutes), the
system returns to its original operation.
II. THE OPERATION SOMETIMES STOPS.
• The remote controller displays "U4" and
"U5", and the operation stops. However, it
will restart in a few minutes.
This is because communication between the
units is shut off and stops the operation due to
noise caused by devices other than the air con-
ditioner.
When the electrical noise decreases, the system
automatically restarts.
III. THE FAN SPEED IS DIFFERENT FROM THE
SETTING.
• Even if the fan speed control button is
pressed, the fan speed does not change.
During the COOLING OPERATION, the airflow
rate is lowered to prevent the carryover of
melted water. In addition, during DEFROST
OPERATION (in the HEATING OPERATION),
the unit stops discharging air so it does not blow
directly toward your body.
After a while, the airflow rate can be changed.
(The airflow rate cannot be set for the PRO-
GRAM DRY OPERATION.)
When the room temperature exceeds the set
temperature the indoor unit goes into whisper
mode. It takes some time until the airflow rate
changes.
Raise the set temperature. After a while, the air-
flow rate changes.
IV. AIR BLOW DIRECTION IS NOT AS SPECIFIED.
• Actual air blow direction is not as shown on
the remote controller.
• Automatic swing setting does not work.
This is because the airflow rate is automatically
controlled.
After a while, the airflow direction can be
changed.
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 from the
centre air outlet is controlled when the indoor
temperature is higher than the set temperature.

After a while, the swing operation starts.
", and
(Refer to "Movement of left and right airflow
flaps" on page 7.)
• The airflow direction display of the remote
controller differs from the actual operation of
the airflow flaps.
<HEATING OPERATION>
This is because the airflow direction from the
centre air outlet is controlled immediately after
the start of operation or when the indoor temper-
ature is higher than the set temperature.
After a while, the airflow direction changes to the
set direction.
(Refer to "Movement of left and right airflow
flaps" on page 7.)
VI. 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.
VII.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.
