the air conditioner is safe and normally does not
leak. However, if the refrigerant leaks and gets
in contact with a naked burner, heater or cooker,
it may generate hazardous compounds.
Turn off the air conditioner and call your local
dealer. Turn on the air conditioner after the
qualiedservicepersonmakessuretoconrm
that the leakage is repaired.
Do not place objects, including rods, your
ngers, etc., in the air inlet or outlet.
Injury may result due to contact with the air
conditioner’s high speed fan blades.
Consult your local dealer regarding cleaning
the inside of the air conditioner.
Improper cleaning may cause breakage of
plastic parts, water leakage and other damage
as well as electric shocks.
Be aware that prolonged, direct exposure to
cool or warm air from the air conditioner, or to
air that is too cool or too warm can be harmful
to your physical condition and health.
Consult your local dealer about installation work.
Doing the work yourself may result in water
leakage,electricshocksorare.
Contact professional personnel about
attachment of accessories and be sure to use
only accessories specied by the manufacturer.
If a defect results from your own workmanship, it
mayresultinwaterleakage,electricshocksorare.

 CHARACTERISTICS OF THE COOLING
OPERATION (COOLING OPERATION AND
AUTOMATIC COOLING OPERATION)
• Aftercontinuousoperationwiththeairow
horizontally or downward, the air conditioner
operateswithdifferentairowdirectionfora
certain period of time to prevent condensation
build-upontheairowdirectionblades.
(Theremotecontrollerdisplaystheairow
direction that is set.)
• If the COOLING OPERATION is used when the
indoor temperature is low, frost adheres to the
heat exchanger of the indoor unit. This can
decrease the cooling capacity. In this case, the
system automatically switches to DEFROST
OPERATION for a while.
During DEFROST OPERATION, the low fan
speed is used to prevent the discharge of
meltwater. (The remote controller displays the
fan speed that is set.)
• When the outside temperature is high, it takes
some time until the indoor temperature reaches
the set temperature.
 CHARACTERISTICS OF THE HEATING
OPERATION (HEATING OPERATION AND
AUTOMATIC HEATING OPERATION)
START OF OPERATION
• It generally takes a longer time for indoor
temperature of the HEATING OPERATION to reach
the set temperature compared to the COOLING
OPERATION. It is advisable to start operation in
advance using the TIMER OPERATION.
After operation is stopped
• The fan operates for about 1 minute to dispel
heat inside the indoor unit.
Perform the following operation to prevent
heating capacity decrease and discharge of
cool air.
AT THE START OF OPERATION AND
AFTER DEFROST OPERATION
• A warm air circulating system is employed, and
therefore it takes some time until the entire
room is warmed up after the start of operation.
• The indoor fan runs to discharge a gentle wind
automatically until the temperature inside the
air conditioner reaches a certain level. At this
time, the DEFROST OPERATION LAMP on the
light receiving unit indicator lights. Leave it as it
stands and wait for a while.
(The remote controller displays the fan speed
that is set.)
• The air discharge direction becomes horizontal
to prevent a draft of cool air to the inhabitants.
(The remote controller will display the set
airowdirection.)
DEFROST OPERATION (Frost removal
operation for the outdoor unit)
• As the frost on the coil of an outdoor unit
increase, heating effect decreases and the
system goes into the DEFROST OPERATION.
• The warm air stops, and the DEFROST
OPERATION LAMP on the light receiving unit
turn on. (The remote controller displays the fan
speed that is set.)
• After maximum 10 minutes of the DEFROST
OPERATION, the air conditioner returns to the
HEATING OPERATION.
• Theairowdirectionbecomeshorizontal.(The
remotecontrollerdisplaystheairowdirection
that is set.)
• During or after the DEFROST OPERATION,
white mist comes out from the air inlet or outlet
of the air conditioner.
• A hissing and “Shuh” sound may be heard
during this particular operation.
Regarding outside air temperature and
heating capacity
• The heating capacity of the air conditioner
declines as the outside air temperature falls. In
such a case, use the air conditioner in
combination with other heating systems.
(When a combustion appliance is used,
ventilate the room regularly.)
Do not use the combustion appliance where
the air from the air conditioner is blown directly
toward it.
• When the warm air stays under the ceiling and
your feet are cold, we recommend that you use
a circulator (a fan to circulate the air inside the
room). For details, consult your local dealer.
• When the indoor temperature exceeds the set
temperature, the indoor unit discharges a
gentle breeze (switches to gentle wind). The
airowdirectionbecomeshorizontal.(The
remote controller displays the fan speed and
airowdirectionthatareset.)
FAN OPERATION
• Only the fan inside the indoor unit operates,
and the air in the room is circulated.

CHARACTERISTICS OF THE PROGRAM
DRY OPERATION
• This operation lowers the humidity without
lowering the indoor temperature. The indoor
temperature when the operation button is
pressed will be the set temperature. At this time,
the fan speed and temperature are set
automatically, so the remote controller does not
display the fan speed and set temperature.
To efcientlylowertheindoortemperatureand
humidity,rstusetheCOOLINGOPERATION
to lower the indoor temperature, and then use
the PROGRAM DRY OPERATION. When the
indoortemperatureislowered,airowfromthe
indoor unit may stop.
• When operating continuously at downward
airowdirection,airblowsintheautomatically
set direction for a period of time to prevent
condensation on the horizontal blades.
• If the PROGRAM DRY OPERATION is used
when the indoor temperature is low, frost forms
on the heat exchanger of the indoor unit. In this
case, the system automatically switches to the
DEFROST OPERATION for a while.
