the air conditioner is not in operation (including when the TIMER
ON is set).
• Do not operate the air conditioner for long periods with the air flow
direction set downward in cooling or dry mode. Otherwise,
condensation may occur on the surface of the horizontal
louver causing moisture to drop on to the floor or on furnishings.
• Do not move the horizontal louver manually. Always use the AIR
DIRECTION or SWING button. If you move this louver manually, it
may malfunction during operation. If the louver malfunctions, stop
the air conditioner once and restart it.
• When the air conditioner is started immediately after it was
stopped, the horizontal louver might not move for approximately
10 seconds.
• Open angle of the horizontal louver should not be set too small, as
COOLING or HEATING performance may be impaired due to too
restricted air flow area.
• Do not operate unit with horizontal louver in closed position.
• When the air conditioner is connected to power (initial power), the
horizontal louver may generate a sound for 10 seconds, this is a
normal operation.
How the air conditioner works
AUTOMATIC OPERATION
• When you set the air conditioner in AUTO mode, it will
automatically select cooling, heating(cooling/heating models
only), or fan only operation depending on what
temperature you have selected and the room temperature.
• The air conditioner will control room temperature automatically
round the temperature point set by you.
• If the AUTO mode is uncomfortable, you can select desired
conditions manually.
operation starts
ECONOMIC OPERATION
When you push ECONO button during cooling, heating (cooling
only type without), or AUTO operation, the air conditioner will start
following operation. The fan speed will be automatically controlled.
In the operation suppression zone where capacity is kept to the
minimum, overcooling is prevented by raising the temperature
setting by 1°C after 1 hour and by 2°C after 2 hours of operation.
The room temperature is thus regulated between the operation
suppression zone and the set temperature. (It depends on the
outdoor temperature.)

Cleaning the air filter
A clogged air filter reduces the cooling efficiency of this unit.
Please clean the filter once every 2 weeks.
Filter handle
4. Remove the air freshening filter from its support frame.
• Clean the air freshening filter at least once a month using a
vacuum cleaner or a brush, and replace it every 4-5 months.
5. Install the air freshening filter back into position.
6. Insert the upper portion of air filter back into the unit taking care
that the left and right edges line up correctly and place filter into
position.
Maintenance
If you plan to idle the unit for a long time, perform the following:
1. Operate the fan for about half a day to dry the inside of the unit.
2. Stop the air conditioner and disconnect power.
Remove the batteries from the remote controller.
3. The outdoor unit requires periodic maintenance and cleaning.
Do not attempt to do this yourself. Contact your dealer or servicer.
Checks before operation
• Check that the wiring is not broken off or disconnected.
• Check that the air filter is installed.
• Check if the air outlet or inlet is blocked after the air conditioner
has not been used for a long time.
CAUTIONS
• Do not touch the metal parts of the unit when removing the filter.
Injuries can occur when handling sharp metal edges.
• Do not use water to clean inside the air conditioner. Exposure to
water can destroy the insulation, leading to possible electric shock.
• When cleaning the unit, first make sure that the power and circuit
breaker are turned off.

Operation tips
The following events may occur during normal operation.
1. Protection of the air conditioner.
Compressor protection
• The compressor can't restart for 3 minutes after it stops.
Anti-cold air (Cooling and heating models only).
• The unit is designed not to blow cold air on HEAT mode,
when the indoor heat exchanger is in one of the following
three situations and the set temperature has not been
reached.
A) When heating has just starting.
B) Defrosting.
C) Low temperature heating.
• The indoor or outdoor fan stop running when defrosting
(Cooling and heating models only).
Defrosting (Cooling and heating models only)
• Frost may be generated on the outdoor unit during heat cycle
when outdoor temperature is low and humidity is high
resulting in lower heating efficiency of the air conditioner.
• During this condition air conditioner will stop heating
operation and start defrosting automatically.
• The time to defrost may vary from 4 to 10 minutes according
to the outdoor temperature and the amount of frost buildup on
the outdoor unit.
2. A white mist coming out from the indoor unit
• A white mist may generate due to a large temperature
difference between air inlet and air outlet on COOL mode in
an indoor environment that has a high relative humidity.
• A white mist may generate due to moisture generated from
defrosting process when the air conditioner restarts in HEAT
mode operation after defrosting.
ENGLISH
8. Heating mode
(For cooling and heating models only)
The air conditioner draws in heat from the outdoor unit and
releases it via the indoor unit during heating operation. When
the outdoor temperature falls, heat drawn in by the air
conditioner decreases accordingly.
At the same time, heat loading of the air conditioner increases
due to larger difference between indoor and outdoor temperature. If a comfortable temperature can't be achieved by the air
conditioner, we suggest you use a supplementary heating
device.
9. Auto-restart function
Power failure during operation will stop the unit completely.
For the unit without Auto-restart feature, when the power
restores, the OPERATION indicator on the indoor unit starts
flashing. To restart the operation, push the ON/OFF button on
the remote controller.
For the unit with Auto-restart feature, when the power restores,
the unit restarts automatically with all the previous settings
preserved by the memory function.
10.Lightning or a car wireless telephone operating nearby
may cause the unit to malfunction.
Disconnect the unit with power and then re-connect the unit
with power again.
Push the ON/OFF button on the remote controller to restart
operation.
3. Low noise of the air conditioner
• You may hear a low hissing sound when the compressor is
running or has just stopped running.
This sound is the sound of the refrigerant flowing or coming to
a stop.
• You can also hear a low "squeak" sound when the
compressor is running or has just stopped running. This is
caused by heat expansion and cold contraction of
the plastic parts in the unit when the temperature is changing.
• A noise may be heard due to louver restoring to its original
position when power is first turned on.
4. Dust is blown out from the indoor unit.
This is a normal condition when the air conditioner has not
been used for a long time or during first use of the unit.
5. A peculiar smell comes out from the indoor unit.
This is caused by the indoor unit giving off smells permeated
from building material, from furniture, or smoke.
6. The air conditioner turns to FAN only mode from COOL or
HEAT (For cooling and heating models only) mode.
When indoor temperature reaches the temperature setting on
air conditioner, the compressor will stop automatically, and the
air conditioner turns to FAN only mode.
The compressor will start again when the indoor temperature
rises on COOL mode or falls on HEAT mode (For cooling and
heating models only) to the set point.
7. Dripping water may generate on the surface of the indoor
unit when cooling in a high relatively humidity (relative
humidity higher than 80%).
Adjust the horizontal louver to the maximum air outlet position
and select HIGH fan speed.
