• When the display shows “
” (time to clean the
air filter), ask a qualified service person to clean
the filters. (Refer to the chapter “Maintenance” in
the operation manual of indoor unit.)
• Keep the indoor unit and remote controller at least
3.5ft. away from televisions, radios, stereos, and
other similar equipment.
Failing to do so may cause static or distorted pic-
tures.
• Do not use other heating devices directly beneath
the indoor unit.
If you do, they might get deformed by the heat.
7. SEASONAL MAINTENANCE
7-1 AT THE BEGINNING OF THE SEASON
Check
• Are the indoor and outdoor unit intake and outlet
vents blocked?
Remove anything that might be blocking them.
Clean the air filter and exterior.
• After cleaning the air filter, be sure to put it back in
the same position.
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.)
7-2 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 page 8 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 air filter and exterior.
• After cleaning the air filter, be sure to put it back in
the same position.
See the operation manual included with the
indoor unit for details on how to clean it.
8. FOLLOWING SYMPTOMS ARE
NOT AIR CONDITIONER TROU-
BLES
8-1 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
controller 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.
8-2 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.
8-3 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 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.
