The following symptoms do not indicate air con-
ditioner malfunction

HEATING OPERATION within 6 hours after the 
power is supplied to the air conditioner.
Some model series perform the following opera-
tion to protect the devices.
If the HEATING OPERATION is performed within 
6 hours after the power is supplied to the air condi-
tioner, the indoor fan stops for about 10 minutes dur-
ing the outdoor unit operation to protect the devices.
The above operation is performed not only for 
installation, but every time the power circuit 
breaker is turned off/on.
For comfortable use, do not turn off the power cir-
cuit breaker during seasonal use of the HEATING 
OPERATION.

I. THE AIR CONDITIONER DOES NOT OPERATE

• The air conditioner does not restart immedi-

ately after the ON/OFF button is pressed.

• The air conditioner does not restart 

immediately when TEMPERATURE SET-
TING button is returned to the former 
position after pushing the button.

If the OPERATION lamp lights, the air condi-
tioner is in normal condition.
It does not restart immediately because a 
safety device operates to prevent overload of 
the air conditioner.
After 3 minutes, the air conditioner will start 
again automatically.

• The air conditioner does not start when 

the display shows “

” and it 

flashes for few seconds after pressing an 
operation button.

This is because the air conditioner is under 
centralized control.
Flashes on the display indicates that the air 
conditioner cannot be controlled by the 
remote controller.

• HEATING OPERATION within 6 hours after 

power is supplied to the air conditioner.

Some model series perform the following 
operation to protect the devices.
If the HEATING OPERATION is performed 
within 6 hours after power is supplied to the 
air conditioner, the indoor fan stops for about 
10 minutes during the outdoor unit operation 
to protect the devices.
The above operation is performed not only 
for installation, but every time the power cir-
cuit breaker is turned off/on.

9. NOT MALFUNCTION OF THE 

AIR CONDITIONER

For comfortable use, do not turn off the 
power circuit breaker during seasonal use of 
the HEATING OPERATION.

• The outdoor unit stops.

This is because the indoor temperature has 
reached the set temperature. 
The indoor unit is in the FAN OPERATION.

COOLING OPERATION 
(AUTOMATIC COOLING OPERATION): 
Lower the set temperature.
HEATING OPERATION 
(AUTOMATIC HEATING OPERATION): 
Raise the set temperature.

The operation starts after a while when the 
air conditioner is in normal condition.

• The remote controller displays “

”, 

and airflow stops.

This is because the air conditioner automati-
cally switches to the DEFROST OPERATION 
to prevent a decrease in heating capacity 
when frost on the outdoor unit increases.
After maximum 10 minutes, the air condi-
tioner 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 
indoor and outdoor units or indoor units and 
remote controllers is shut off and stopped 
due to noise caused by devices other than 
the air conditioner.
When the electrical noise decreases, the air 
conditioner automatically restarts.

III. THE FAN SPEED IS DIFFERENT FROM THE 

SETTING

• Pressing the fan speed control button 

does not change the fan speed.

During the COOLING OPERATION, the low 
fan speed or a gentle wind is used to prevent 
the discharge of melt water. 
During the DEFROST OPERATION (HEAT-
ING OPERATION), the wind from the air con-
ditioner stops to prevent air discharge 
directly toward your body. After a while, the 
fan speed can be changed.
(The fan speed cannot be set for the PRO-
GRAM DRY OPERATION.)
When the room temperature reaches the set 
temperature during the HEATING OPERA-
TION, the outdoor unit stops and the indoor 
unit goes into gentle wind. 
It takes some time until the fan speed changes.
Raise the set temperature. 
After a while, the fan speed changes.
