8-2 AT THE END OF THE SEASON
On a clear day, use fan operation for around half a
day to thoroughly dry out the interior of the unit.
• Refer to chapter 6 for details on fan operation.
Turn off the power.
• When the power is shut off, the characters in the
remote controller display disappear.
• When the power is on, the unit consumes up to
several dozen Watts of power.
Turn off the power to conserve energy.
Clean the exterior.
• See the operation manual included with the
indoor unit for details on how to clean it.
9. FOLLOWING SYMPTOMS ARE NOT
AIR CONDITIONER TROUBLES
9-1 THE SYSTEM DOES NOT OPERATE
• The air conditioner does not start immediately
when restart the operation after stop the oper-
ation or change operation mode after set the
operation mode.
If the operation lamp lights, the system is in nor-
mal condition.
To prevent overloading of the compressor motor,
the air conditioner starts 5 minutes after it is turned
ON again in case it was turned OFF just before.
• If “Centralized Control” is displayed on the
remote controller and pressing the operation
button causes the display to blink for a few
seconds.
This indicates that the central device is controlling
the unit.
The blinking display indicates that the remote
control cannot be used.
• The system does not start immediately after
the power supply is turned on.
Wait one minute until the micro computer is pre-
pared for operation.
9-2 IT STOPS SOMETIMES
•
The remote controller display reads “U4” or “U5”
and stops but then restarts after a few minutes.
This is because the remote control is intercepting
noise from electrical appliances other than the air
conditioner, and this prevents communication
between the units, causing them to stop.
Operation automatically restarts when the noise
goes away.
9-3 COOL/HEAT CANNOT BE CHANGED
OVER
• When the display shows
“”
(changeover under control).
It shows that this is a slave remote controller.
Refer to “Setting the master remote controller”.
• When the cool/heat selector switch is
installed and the display shows
“”
(changeover under control).
This is because cool/heat changeover is con-
trolled by the cool/heat selector. Ask your Daikin
dealer where the remote control switch is installed.
9-4 FAN OPERATION IS POSSIBLE, BUT
COOLING AND HEATING DO NOT
WORK
• Immediately after the power is turned on.
The micro computer is getting ready to operate.
Wait 10 minutes.
9-5 THE FAN STRENGTH DOES NOT COR-
RESPOND TO THE SETTING
• The fan strength does no change even if the
fan strength adjustment button in pressed.
During heating operation, when the room temper-
ature reaches the set temperature, the outdoor
unit goes off and the indoor unit changes to whis-
per fan strength.
This is to prevent cold air blowing directly on occu-
pants of the room.
The fan strength will not change even if the button
is changed, when another indoor unit is in heating
operation.
9-6 THE FAN DIRECTION DOES NOT COR-
RESPOND TO THE SETTING
• The fan direction does not correspond to the
remote control display.
The fan direction does not swing.
This is because the unit is being controlled by the
micro computer. Refer to “Adjusting the air flow
direction”.
9-7 WHITE MIST COMES OUT OF A UNIT
Indoor unit
•
When humidity is high during cooling operation.
If the interior of an indoor unit is extremely con-
taminated, the temperature distribution inside a
room becomes uneven. It is necessary to clean
the interior of the indoor unit. Ask your Daikin
dealer for details on cleaning the unit. This opera-
tion requires a qualified service person.

- Electrical work 7
- English 3 7
- For refrigerant leakage consult your dealer refrigerant leakage in excess of the level of con centration limits may result in oxygen deficiency when the air conditioner is installed in a small room it is necessary to take proper measures so that the amount of any leaked refrigerant will not exceed the limiting concentration even if it leaks 7
- Make sure that the air conditioner is located in a sufficiently ventilated place not surrounded by obstacles 7
- Make sure that the drainpipe is installed prop erly to drain water if no water is discharged from the drainpipe while the air conditioner is cooling operation the drain pipe may be clogged with dust or dirt and water leakage from the indoor units may result stop operating the air conditioner and consult your dealer 7
