MALFUNCTION

 

OF

 

THE

 

AIR

 

CONDITIONER

The following symptoms do not indicate air conditioner malfunction.

The system does not operate

The system does not restart immediately after the ON/OFF
button is pressed.
If the OPERATION lamp lights, the system is in its normal
operating condition.
It does not restart immediately because one of its safety devices
actuates to prevent the system from being overloaded.
The system will turn on again automatically after three minutes.

The system does not restart immediately when the
TEMPERATURE SETTING button is returned to its former
position after pushing.
It does not restart immediately because one of its safety devices
actuates to prevent the system from being overloaded.
The system will turn on again automatically after three minutes.

The system does not start when the display shows "

"

(EXTERNAL CONTROL ICON) and it flashes for a few seconds
after pressing an operation button.
This is because the system is controlled or disabled by another
controller with a higher priority.
When the display flashes, it indicates that the system cannot be
controlled by this indoor unit.

The system does not start immediately after the power supply is
turned on.
Wait one minute until the micro computer is prepared for
operation.

The outdoor unit has stopped.
This is because the room temperature has reached the set
temperature. The unit switches to fan operation.

"

" (EXTERNAL CONTROL ICON) is displayed on the

remote controller and the actual operation is different from the
remote controller setting.
For multi split models, the micro computer executes the following
control depending on the operation mode of other indoor units.
-

Before you start to operate, the other indoor unit(s) is (are) 
already operating. When the operation mode of this unit is 
different from your choice, the indoor unit of your room may 
be put in waiting condition. (Fan: Stop, Horizontal flap: 
Horizontal position)

-

When the total cooling capacity of all indoor units which are 
operating is beyond the capacity limit of the outdoor unit, your 
indoor unit will be put in waiting condition. (Fan and 
horizontal flap: Same as setting: (cooling only model only))

-

After cooling mode operation of the unit of your room, when 
other unit(s) start to operate, the unit of your room may 
operate as follows: Fan: L tab, Horizontal flap: Horizontal 
position.

The fan speed is different from the setting. Pressing the fan
speed contol button does not change the fan speed.
When the room temperature reaches the set temperature in
heating mode, the capacity supply from the outdoor unit has
stopped and the indoor unit operates in fan only mode (L tab). In
case of multi split, the indoor unit alternately operates fan stop
and fan only mode (L tab).
This is to prevent the cool air from being blown directly onto
anyone present in the room.

Air blow direction is not as specified

Actual air blow direction is not as shown on the remote
controller.

Automatic swing setting does not work. 

Refer to the manual of the remote controller.

White mist comes out of a unit

When humidity is high during cooling operation (In oily or dusty
places).
If the inside of an indoor unit is extremely contaminated, the
temperature distribution inside a room becomes uneven. It is
necessary to clean the inside of the indoor unit. Ask your dealer
for details on cleaning the unit. This operation requires a
qualified service person.

When the system is changed over to HEATING OPERATION
after DEFROST OPERATION.
Moisture generated by DEFROST becomes steam and exits.

Noise of air conditioners

A "ringing" sound is heard after the unit is started.
This sound is generated by the temperature regulator working. It
will quiet down after about a minute.

A continuous low "hissing" sound is heard when the system is in
COOLING or DEFROST OPERATION.
This is the sound of refrigerant gas flowing through both indoor
and outdoor units.

A "hissing" sound which is heard at the start or immediately after
the stop of operation or which is heard at the start or
immediately after the stop of DEFROST OPERATION.
This is the noise of refrigerant caused by flow stop and flow
change.
