8. SEASONAL MAINTENANCE
CAUTION
• Do not touch the air inlets or aluminum fins of
the outside or indoor units.
Touching them may result in injury.
• Do not wash the outside or indoor units with
water.
An electric shock or fire may result.
• Watch your steps at the time of air filter clean-
ing etc.
If the scaffold is unstable, you may fall or topple
down, thus causing injury.
• Be sure to stop the operation, and turn the
breaker off before cleaning.
This may cause electric shock and injury.
• Consult with the dealer for cleaning the inte-
rior of the indoor units.
Incorrect cleaning may damage the plastic parts
and cause failures, such as water leakage, and an
electric shock may result.
8-1 AT THE BEGINNING OF THE SEASON
Check
• Are the indoor and outside unit intake and outlet
vents blocked?
Remove anything that might be blocking them.
Clean the exterior.
• See the operation manual included with the
indoor unit for details on how to clean it.
Turn the power on.
• When the power comes on, the characters in the
remote controller display appear.
(To protect the unit, turn the power on at least 6
hours before operating it. This makes operation
smoother.)
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 restarting or changing 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 1 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.
