WARNING
■
When an abnormality (such as a burning smell) occurs, stop operation and turn the breaker OFF.
Continued operation in an abnormal condition may result in troubles, electric shocks or fire.
Consult the service shop where you bought the air conditioner.
■
Do not attempt to repair or modify the air conditioner by yourself.
Incorrect work may result in electric shocks or fire.
Consult the service shop where you bought the air conditioner.
If one of the following symptoms takes place, call the service shop immediately.
Case Explanation
The outdoor fan rotates while the air
conditioner is not in operation.
■
After operation is stopped:
•
The outdoor fan continues rotating for another 60 seconds for system protection.
■
While the air conditioner is not in operation:
•
When the outdoor temperature is very high, the out door fan starts rotating
for system protection.
The operation stopped suddenly.
(OPERATION lamp is on)
■
For system protection, the air conditioner may stop operating on a sudden
large voltage fluctuation.
It automatically resumes operation in about 3 minutes.
“ ” is displayed on the remote
controller, and the displayed contents flash
for several seconds when an operation but-
ton is pressed.
When three short “beep” sounds are issued
in the case of wireless remote controller.
•
The air conditioner is controlled by the central equipment.
Flashing of the displayed contents indicates that the remote controller is
invalid for control.
COOL/HEAT cannot be changed over.
•
When the display shows “ ”
(CHANGEOVER UNDER CONTROL),
it shows that this is a slave remote
controller.
•
When the cool/heat changeover
remote control switch is installed
and the display shows “
”
(CHANGEOVER UNDER CONTROL).
When a long “beep” sound is issued in
the case of wireless remote controller.
•
Refer to page 13.
•
This is because cool/heat changeover is controlled by the cool/heat
changeover remote control switch. Ask your Daikin dealer where the
remote control switch is installed.
The liquid crystal of the remote control-
ler shows “
” immediately after the
power supply is turned on.
•
This shows that the remote controller is in normal condition.
This continuoues for one minute.
The compressor in the outdoor unit does
not stop after a short HEATING operation.
•
This is to prevent oil and refrigerant from remaining in the compressor.
The unit will stop after 5 to 10 minutes.
The inside of an outdoor unit is warm
when the unit has stopped
•
This is because the crankcase heater is warming the compressor even
while the outdoor unit is stopped so that the compressor can start smoothly.
When the air conditioner has not been used
(the power has been off) for a long time.
•
For protecting the mechanism, supply the power for 6 hours at first, then
operate the air conditioner.
Warm air exits the unit even though it is off.
You can feel hot air coming out of the unit.
•
Multiple units are operating on the same system, so if a unit in another
room is operating, some refrigerant will flow through the stopped units, too.
Call the service shop immediately.
■
After a power failure
The air conditioner automatically resumes operation
in about 3 minutes. You should just wait for a while.
■
Lightning
If lightning may strike the neighbouring area, stop oper-
ation and turn the breaker OFF for system protection.
■
The power cord is abnormally hot or damaged.
■
An abnormal sound is heard during operation.
■
The safety breaker, a fuse, or the earth leakage breaker
cuts off the operation frequently.
■
A switch or a button often fails to work properly.
■
There is a burning smell.
■
Water leaks from the indoor unit.
Turn the breaker OFF
and call the service
shop.
