User`s manual
When you start the air conditioner, when the compressor starts or stops
during operation or when you stop the air conditioner, you may hear gurgling
sound. this means that the refrigerating liquid is circulating, it is quite normal.
This is caused by heat expansion or contraction of plastic.
Those are the sounds of an air conditioner controlling itself automati-
cally.
Air blown out of the indoor unit sometimes smells.
This is caused by tobacco smoke or cosmetics stuck inside the unit.
If the air conditioner is used in a restaurant etc with dense oil fumes
around, some white mist may escape from the air outlet .
If so, call the dealer to clean the heat exchanger.
The mist sometimes switches automatically to FAN mode to prevent
accumulation of frosty film on the indoor unit heat exchanger. It will soon
revert to cooling mode.
In order to cool down the remaining heat on the auxiliary heater, the blower
may operate continuously for about 40 seconds after the unit is stopped. Do
not turn off the power supply switch before the blower stops.
Even if you switch on, you cannot use
cooling, dehumidifying or heating for three
minutes after the air conditioner has
stopped. as a result of the protection timer
being activated.
(During this time the unit operates in FAN mode.)
During the dehumidifying operation, the blower is operated in the weak
blowing mode or stopped alternately in order to prevent an excessive
cooling or rising of humidity.
When the power switch is turned on, the auto swing is repeated twice. It
is not a trouble. Moreover, it is automatically brought into the horizontal
position in the “HOT KEEP”.
This results when frost accumulated on the outdoor unit is removed
(During defrosting operation).
In the defrosting operation or the heating operation at high outside
temperature, the function to stop the blower is activated. On the con-
trary, the function that automatically controls the number of blower
operates at low atmospheric temperature.
When the power failure compensation is set to “valid”, after the power
recovery the operation starts with the same status as that of before the
power failure or before turning off the power switch.
When the temperature setting is fixed, the setting temperature does not
change even if the
switch is pressed.
You hear a slight
gurgling sound.
You hear a slight cracking sound.
Hissing or gurgling sound is heard from
the unit stopped.
You smell something.
During the operation,
some white mist escapes
from the indoor unit.
The unit switches to FAN mode during
cooling.
Blower of indoor unit does not stop even
if the operation is stopped during
heating cycle.
You can not restart the air
conditioner immediately after
you have stopped it.
Air does not blow or the fan speed can
not be changed during dehumidifying.
The swing flap operates by itself.
(In the case of FDT.)
Water or steam generates from the
outdoor unit during heating.
The blower in the outdoor unit does not
rotate during operation.
Operation was started just after the
power switch was turned on.
The setting temperature does not
change. (The setting temperature
indication flick-ers.)
The following does not mean malfunctions of the unit.
WARNING
There is a danger that the blower suddenly begins to rotate even if it is
stopping now, therefore do not insert your finger or a bar. Neglecting
this will result in injury.
Wait for
three
minutes.
Unit does
not start.

Keep on pressing the setting switch for 3 seconds.
By the above operation the temperature setting can be fixed.
When the air-conditioner is stopped:
Press ON/OFF switch to make the air-conditioner in [Opera-
tion] mode.
Press the temperature setting switch.
Press or switch to set the unit to the temperature to
be fixed.
What is the power failure compensation?
●
It means the function that when the power is restored after the power failure or the power switch is intentionally
turned off, the operation is automatically restarted with the setting condition of remote controller before power
failure. When the air-conditioner had been stopping before the power failure, it still keeps on stopping after
power recovery.
●
However, resetting by the remote control is necessary for the following items.
1. Timer setting —— It has been cancelled.
2. Auto swing (for the remote control equipped with this function) —— It is stopped at the horizontal position.

The remote controller is equipped with a power failure compensation function, so it is possible to make the power
failure compensation invalid. (At the delivery from the factory, it is set to valid.)
Consult the dealer you have purchased.
When the power failure compensation is set to valid, ensure to turn off the power switch after stopping the operation.
(If the power switch is turned off during the operation mode, the blower of the indoor unit begins to rotate at the
same time when the power switch is turned on. In addition, the outdoor unit begins to operate after about 3 minutes
of the power switch on.)
●
Release method: Keep on pressing the setting switch for 3 seconds
during operation.
●
When the temperature setting switch is pressed while the tempera-
ture setting is fixed, the setting temperature indication flickers for 4
seconds.
The temperature setting can be fixed by the following operation. After the fixation the temperature change by the
temperature setting switch on the remote controller becomes impossible.
