When you think there is
something wrong
The following symptoms do not indicate air conditioner
malfunction:
Symptom 1: The system does not operate
Example Reason
The system does not restart
immediately after the ON/
OFF button is pressed.
If the OPERATION lamp
lights, the system is in
normal condition. It does not
restart immediately because
a safety device operates
to prevent overload of the
system. After 3 minutes, the
system will turn on again
automatically.
If operation stops as a result
of changing the temperature
setting, there will be a delay
before operation restarts
if the setting is lowered (in
COOLING) or raised (in
HEATING) again.
It does not restart
immediately because a
safety device operates to
prevent overload of the
system.
After 3 minutes, the
system will turn on again
automatically.
If the reception beep is
rapidly repeated 3 times
(It sounds only twice when
operating normally.)
Control is set to the optional
controller for centralized
control.
If the DEFROST lamp on
the indoor unit’s display is lit
when heating is started.
This indication is to warn
against cold air being
blown from the unit. There
is nothing wrong with the
equipment.
The outdoor unit stops. Because the room
temperature reaches to the
set temperature. The indoor
unit goes into FAN operation.
Symptom 2: The unit stops once in a while
Example Reason
The remote controller
indicates “U4” and “U5”, the
unit stops. Within several
minutes the unit restarts.
Due to electrical noise
other than that from
the air conditioner, the
communication between the
units is cut off and the unit
stops.
When the noise is gone, the
unit automatically restarts.
Symptom 3: No changeover is available between
HEATING and COOLING modes
Example Reason
The indoor unit makes a
long beep sound.
When operation changeover
is under control, the control
is set to the mode that
cannot be carried out.
Symptom 4: Air ow rate cannot be obtained as set
Example Reason
During HEATING operation,
even if the FAN SPEED
CONTROL button is
pressed, the air ow rate
does not change.
When the room temperature
reaches the indoor unit set
temperature, the outdoor
unit stops and the air ow
rate of indoor unit drops to
the minimum.
This is to avoid the cold air
from getting in contact with
the people in the room.
Symptom 5: Air discharge direction is not as set
Example Reason
The remote controller
indication and the air
discharge direction is not the
same.
Air discharge direction swing
is impossible.
Because it is controlled by
microcomputer. Refer to
“AIR FLOW DIRECTION
ADJUST” on page 5.
Symptom 6: Only a part of indication shows
Example Reason
Even if the unit is operated,
only the operation indication
shows, or even if the
indication shows, soon after,
the indication other than that
for operation disappears.
The corresponding indoor
unit is that for multi-system
and the remote controller is
set to the multi-system.
Symptom 7: No indication shows or all indication show
Example Reason
When the remote controller
button is pressed.
The battery is dead.
Symptom 8: Insufcient cooling
Example Reason
It is in DRY operation. The DRY operation
is an operation mode
trying to keep the room
temperature constant as
much as possible. Refer
to “COOLING, HEATING,
AUTOMATIC, FAN and DRY
operation” on page 4.
