Note(Onlyforwirelessremotecontroller):
■ When using the wireless remote controller, point it towards the receiver on the indoor unit.
■ If the 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 conrm that the signal transmitted from the remote controller has been
received. Signals can be received up to approximately 7 meters, 275-19/32 inch in a direct line
from the indoor unit in an area 45° to the left and right of the unit. However, illumination such as
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 inspected.
Consult your dealer for service.
■ Handle the remote controller carefully! Do not drop the remote controller or subject it to strong
shocks. In addition, do not get the remote controller wet or leave it in a location with high humidity.
■ To avoid misplacing the remote controller, install the holder included with the remote controller on
a wall and be sure to always place the remote controller in the holder after use.

Whattheblinkingmodeiconmeans
The mode icon will blink when other indoor units in the same refrigerant
system (connected to the same outdoor unit) are already operated in a
different mode. In this case, the rest of the unit in the same group can
only be operated in the same mode.
Automaticoperation
■According to a set temperature, cooling operation starts if the room tem-
perature is too hot and heating operation starts if the room temperature
is too cold.
■During automatic operation, if the room temperature changes and re-
mains 2.0 °C, 4 °F or more above the set temperature for 15 minutes,
the air conditioner switches to cool mode. In the same way, if the room
temperature remains 2.0 °C, 4 °F or more below the set temperature for
15 minutes, the air conditioner switches to heat mode.

►Cleaningthelters
• Clean the lters using a vacuum cleaner. If you do not have a vacuum
cleaner, tap the lters against a solid object to knock off dirt and dust.
• If the lters are especially dirty, wash them in lukewarm water. Take care
to rinse off any detergent thoroughly and allow the lters to dry completely
before putting them back into the unit.
Caution:
• Donotdrytheltersindirectsunlightorbyusingaheatsource,
suchasanelectricheater:thismaywarpthem.
• Donotwashtheltersinhotwater(above122°F[50°C]),asthis
maywarpthem.
• Makesurethattheairltersarealwaysinstalled.Operatingtheunit
withoutairlterscancausemalfunction.
Caution:
• Beforeyoustartcleaning,stopoperationandturnOFFthepower
supply.
• Indoorunitsareequippedwithlterstoremovethedustofsucked-
inair.Cleantheltersusingthemethodsshowninthefollowing
sketches.

7.TroubleShooting
Having trouble? Here is the solution. (Unit is operating normally.)
Air conditioner does not heat or cool well. ■ Clean the lter. (Airow is reduced when the 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?
When heating operation starts, warm air does not blow from the indoor
unit soon.
■ Warm air does not blow until the indoor unit has sufciently warmed up.
During heating mode, the air conditioner stops before the set room tem-
perature is reached.
■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.
When the airow direction is changed, the vanes always move up and
down past the set position before nally stopping at the position.
■ When the airow direction is changed, the vanes move to the set posi-
tion after detecting the base position.
A owing water sound or occasional hissing sound is heard. ■ These sounds can be heard when refrigerant is owing in the air con-
ditioner or when the refrigerant ow is changing.
A cracking or creaking sound is heard. ■These sounds can be heard when parts rub against each due to expan-
sion and contraction from temperature changes.
The room has an unpleasant odor. ■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.
A white mist or vapor is emitted from the indoor unit. ■If the indoor temperature and the humidity are high, this condition may
occur when operation starts.
■ During defrosting mode, cool airow may blow down and appear like a
mist.
Water or vapor is emitted from the outdoor unit. ■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 exchanger.
■During defrosting mode, water on the heat exchanger evaporates and
water vapor may be emitted.
The operation indicator does not appear in the wired remote controller
display. (*1) ■Turn on the power switch. “ ” will appear in the wired remote controller
display.
“ ” appears in the wired remote controller display. (*1) ■During central control, “ ” appears in the wired remote controller
display and air conditioner operation cannot be started or stopped using
the wired remote controller.
When restarting the air conditioner soon after stopping it, it does not
operate even though the ON/OFF button is pressed.
■Wait approximately three minutes.
(Operation has stopped to protect the air conditioner.)
Air conditioner operates without the ON/OFF button being pressed. (*1) ■Is the on timer set?
Press the ON/OFF button to stop operation.
■Is the air conditioner connected to a central wired remote controller?
Consult the concerned people who control the air conditioner.
■Does “ ” appear in the wired remote controller display?
Consult the concerned people who control the air conditioner.
■Has the auto recovery feature from power failures been set?
Press the ON/OFF button to stop operation.
Air conditioner stops without the ON/OFF button being pressed. (*1) ■Is the off timer set?
Press the ON/OFF button to restart operation.
■Is the air conditioner connected to a central wired remote controller?
Consult the concerned people who control the air conditioner.
■Does “ ” appear in the wired remote controller display?
Consult the concerned people who control the air conditioner.
Wired remote controller timer operation cannot be set. (*1) ■Are timer settings invalid?
If the timer can be set, , or appears in the wired remote controller
display.
“PLEASE WAIT” appears in the wired remote controller display. (*1) ■The initial settings are being performed. Wait approximately 3 minutes.
An error code appears in the remote controller display. ■The protection devices have operated to protect the air conditioner.
■Do not attempt to repair this equipment by yourself.
Turn off the power switch immediately and consult your dealer. Be sure
to provide the dealer with the model name and information that appeared
in the remote controller display.
Draining water or motor rotation sound is heard. ■When cooling operation stops, the drain pump operates and then stops.
Wait approximately 3 minutes.
The fan speed changes in spite of not changing the setting. ■Not to blow out cold air at the beginning of heating operation, the air
conditioner automatically adjusts the fan speed gradually from lower to
the set speed. It also adjust its fan speed to protect the fan motor when
return air temperature or fan speed excessively rises.
