Cool/Dry/Fan/Heat/Automatic (cool/heat)/Ventilation modes are available.
Note:
Heat and Automatic mode can not be available for cooling only units.
z
Ventilation mode: only indicated on the following condition. Wired remote

According to a set temperature, cooling operation starts if the room
temperature is too hot and heating operation starts if the room temperature is too cold.
During automatic operation, if the room temperature changes and
remains 2 °C, 4 °F or more above the set temperature for 15 minutes,
the air conditioner switches to cooling mode. In the same way, if the
room temperature remains 2 °C, 4 °F or more below the set temperature for 15 minutes, the air conditioner switches to heating mode.

3.3. Fan speed setting
Note:
The number of available fan speeds depends on the type of unit
connected.
In the following cases, the actual fan speed generated by the unit
will differ from the speed shown the remote controller display.
1. When the unit is in STANDBY or DEFROST states.
2. When the temperature of the heat exchanger is low in the heat-
ing mode. (e.g. immediately after heating operation starts)
3. In HEAT mode, when room temperature is higher than the tem-
perature setting.
4. When the unit is in DRY mode.
3.4. Airfl ow direction setting
During swing operation, the directional indication an the screen does not
change in sync with the directional vanes on the unit.
Available directions depend on the type of unit connected.
In the following cases, the actual air direction will differ from the
direction indicated on the remote controller display.
1. When the unit is in STANDBY or DEFROST states.
2. Immediately after starting heater mode (while the system is
waiting for the mode change to take effect).
3.
In heat mode, when room temperature is higher than the temperature setting.
<[Manual] To Change the Airfl ow’s Left/Right Direction>
* The louver button 7 cannot be used.
• Stop the unit operation, hold the lever of the louver,
and
adjust to the desired direction.
* Do not set to the inside direction when the unit is
in the cooling or drying mode because there is a
risk of condensation and water dripping.
3.5. Ventilation

7. Trouble Shooting
Having trouble? Here is the solution. (Unit is operating normally.)
Air conditioner does not heat or cool well.
When heating operation starts, warm air does not blow from the indoor
unit soon.
During heating mode, the air conditioner stops before the set room temperature is reached.
Note:
When 2 or more different types of indoor unit are controlled, the cleaning
●
period differs with the type of fi lter. When the master unit cleaning period
arrives, “FILTER” is displayed. When the fi lter display goes off, the cumu-
lative time is reset. (only for wired remote controller)
“FILTER” or “Clean Filter” indicates the cleaning period when the air
●
conditioner was used under general indoor air conditions by criteria time.
Since the degree of dirtiness depends on the environmental conditions,
clean the fi lter accordingly.
The fi lter cleaning period cumulative time differs with the model.
●
This indication is not available for IR wireless remote controller.
●
Clean the fi lter. (Airfl ow is reduced when the fi lter is dirty or clogged.)
■
Check the temperature adjustment and adjust the set temperature.
■
Make sure that there is plenty of space around the outdoor unit. Is the
■
indoor unit air intake or outlet blocked?
Has a door or window been left open?
■
Warm air does not blow until the indoor unit has suffi ciently warmed
■
up.
When the outdoor temperature is low and the humidity is high, frost
■
may form on the outdoor unit. If this occurs, the outdoor unit performs
a defrosting operation. Normal operation should begin after approximately 10 minutes.

7. Trouble Shooting
Having trouble? Here is the solution. (Unit is operating normally.)
Airfl ow direction changes during operation or airfl ow direction cannot be
set.
When the airfl ow direction is changed, the vanes always move up and
down past the set position before fi nally stopping at the position.
A fl owing water sound or occasional hissing sound is heard.
A cracking or creaking sound is heard.
The room has an unpleasant odor.
A white mist or vapor is emitted from the indoor unit.
Water or vapor is emitted from the outdoor unit.

When restarting the air conditioner soon after stopping it, it does not operate even though the ON/OFF button is pressed.
Air conditioner operates without the ON/OFF button being pressed. (*1)■ Is the on timer set?
Air conditioner stops without the ON/OFF button being pressed. (*1)
Wired remote controller timer operation cannot be set. (*1)
“PLEASE WAIT” appears in the wired remote controller display. (*1)
An error code appears in the remote controller display.
Draining water or motor rotation sound is heard.
Noise is louder than specifi cations.
Nothing appears in the IR wireless remote controller display, the display
is faint, or signals are not received by the indoor unit unless the IR wireless remote controller is close. (*2)
The operation lamp near the receiver for the IR wireless remote controller on the indoor unit is blinking. (*2)
During cooling mode, the vanes automatically move to the horizontal
■
(down) position after 1 hour when the down (horizontal) airfl ow direc-
tion is selected. This is to prevent water from forming and dripping
from the vanes.
During heating mode, the vanes automatically move to the horizontal
■
airfl ow direction when the airfl ow temperature is low or during defrost-
ing mode.
When the airfl ow direction is changed, the vanes move to the set po-
■
sition after detecting the base position.
These sounds can be heard when refrigerant is fl owing in the air con-
■
ditioner or when the refrigerant fl ow is changing.
These sounds can be heard when parts rub against each due to ex-
■
pansion and contraction from temperature changes.
The indoor unit draws in air that contains gases produced from the
■
walls, carpeting, and furniture as well as odors trapped in clothing,
and then blows this air back into the room.
If the indoor temperature and the humidity are high, this condition
■
may occur when operation starts.
During defrosting mode, cool airfl ow may blow down and appear like
■
a mist.
During cooling mode, water may form and drip from the cool pipes
■
and joints.
During heating mode, water may form and drip from the heat ex-
■
changer.
During defrosting mode, water on the heat exchanger evaporates and
■
water vapor may be emitted.
During central control, “

Note:
When using the IR wireless remote controller, point it towards the receiver on the indoor unit.
If the IR wireless remote controller is operated within approximately 2 minutes after power is
supplied to the indoor unit, the indoor unit may beep twice as the unit is performing the initial
automatic check.
The indoor unit beeps to confi rm that the signal transmitted from the IR wireless remote con-
troller has been received. Signals can be received up to approximately 7 meters in a direct
line from the indoor unit in an area 45° to the left and right of the unit. However, illumination
such as fl uorescent lights and strong light can affect the ability of the indoor unit to receive
signals.
If the operation lamp near the receiver on the indoor unit is blinking, the unit needs to be in-
spected. Consult your dealer for service.
Handle the IR wireless remote controller carefully! Do not drop the IR wireless remote con-
troller or subject it to strong shocks. In addition, do not get the IR wireless remote controller
wet or leave it in a location with high humidity.
To avoid misplacing the IR wireless remote controller, install the holder included with the IR
wireless remote controller on a wall and be sure to always place the IR wireless remote controller in the holder after use.
