ADJUSTING THE AIR DEFLECTORS
1. NON DUCT
Adjustment of the conditioned air in the upward and
downward directions.
According to “Dehumidifying” or “Cooling” operation, the
horizontal air deflector is automatically set to the proper angle
suitable for each operation. The deflector can be swung up
and down and also set to the desired angle using the
“
(AUTO SWING)” button. (If the angle of the deflector is
changed, it will not return to the auto-set position after
operations start unless the operation mode is switched.)
• If the “ (AUTO SWING)” button is pressed once,
the horizontal air deflector swings up and down. If
the button is pressed again, the deflector stops in its
current position.
• Use the horizontal air deflector within the adjusting
range shown on the right.
• When the auto swing operation is performed, if the
horizontal air deflector is moved manually, the swing
range may drift. However, it will return to the original
operation range after a short time.
About 65°
2. FULL DUCT • SEMI DUCT
• As shown in the diagram, perform by holding the horizontal air deflector.
• When adjusting the air direction, use a stepladder, etc.

Be sure to clean the filter once every two weeks so as not to consume
electricity unnecessarily.
PROCEDURE
Remove suction grille before removing filter.
• Lift up one side of suction grille and remove by inclining it (refer
to diagram).
• Press claw downward to remove filter.
1
Remove dust from the filter using a vacuum cleaner.
If there is too much dust, use neutral detergent. After using neutral
detergent, wash with clean water and dry in the shade.
2
Install the filters.
Slightly lift the suction grille and close as original state.
3
CAUTION
• Do not wash with hot water at more than 40°C. The filter may shrink.
• When washing it, shake off moisture completely and dry it in the shade; do not expose it directly to the sun.
The filter may shrink.
• Do not operate the air conditioner with the filter removed. Dust may enter the air conditioner and cause
trouble.

2. CLEANING OF SUCTION GRILLE
• Wipe it with a soft dry cloth.
• When it is excessively dirty, wipe with soft cloth soaked in lukewarm water or neutral detergent. Then wipe
thoroughly with a soft dry cloth.
CAUTION
• Never clean with hot water (above 40°C), benzine, gasoline, acid, thinner or a
brush, because it will damage the plastic surface and the coating.
3. MAINTENANCE AT BEGINNING OF LONG OFF PERIOD
• Running the unit setting the operation mode to (FAN) and the fan speed
to HI for about half a day on a fine day, and dry the whole of the unit.

Heating Capability
• This room air conditioner utilizes a heat pump system that absorbs
exterior heat and brings it into a room to be heated. As the ambient
temperature gets lower, heating capability will also lower. In such a
situation, the PAM and inverter work to increase compressor rpm to keep
the unit’s heating capability from decreasing. If the unit’s heating
performance is still unsatisfactory, other heating appliances should be
used to augment this unit’s performance.
• The air conditioner is designed to heat an entire room so that it may take some time before you feel warm. Timer
operation is recommended for effective preheating ahead of the desired time.
Cooling and Dehumidifying Capabilities
• If the heat present in a room exceeds the unit’s cooling capacity (for example, if there are many people in the room
or other heating appliances are used), the preset room temperature may not be reached.
CAPABILITIES
INFORMATION
CAUTION
Do not use a stove
or any other high-
temperature devices
in proximity to the
indoor unit.
PROHIBITION
• When fan speed, room temperature are set with the remote controller before starting manual operation and
the buttons are released, the indication of settings will go off in 10 seconds and only the operation mode will
be displayed.
• Pressing the button while the unit is in operation will let the protective circuit work so that the unit will not
operate for approximately 3 minutes.
• If you feel cold wind during warming operation with the (HI) fan speed or want to make the unit operation
quieter after the room is heated, use of (AUTO) setting is recommended.
• With the (LOW) setting, the unit’s cooling capability will lower slightly.
VARIOUS FUNCTIONS
• When the timer has been programmed, the unit will not operate even if the set time is reached unless the unit
receives a signal from the remote controller. Confirm that timer programming is complete (beep) and the
TIMER lamp of the indoor unit lights.
• If the (SLEEP) button is pressed while the ON/OFF timer is programmed, the sleep timer takes priority.
• During sleep timer operation, the fan speed sets to (LOW) regardless of the preset speed. The remote
controller display indication will remain unchanged even with the (LOW) setting.

Check to see if the unit’s earth line has been connected
correctly.
If the earth line is disconnected or faulty, unit failure or electric
shock hazard may result.
Check to see if the mounting frame has rusted excessively
or if the outdoor unit has tilted or become unstable.
It could collapse or fall, causing injury.
WHEN ASKING FOR SERVICE, CHECK THE FOLLOWING POINTS.
CONDITION CHECK THE FOLLOWING POINTS
• Do the batteries need replacement?
• Is the polarity of the inserted batteries correct?
• Is the air filter blocked with dust?
• Is the set temperature suitable?
• Have the top and bottom air deflectors been adjusted to their correct
positions according to the operation mode selected?
• Are the air inlets or air outlets of indoor and outdoor units blocked?
• Is the fan speed “LOW”?
WARNING
WARNING
AFTER SALES SERVICE AND WARRANTY
• Is the fuse all right?
• Is the voltage extremely high or low?
• Is the circuit breaker “ON”?
• Is the setting of operation mode different from other indoor units?
When it does not operate.
When it does not cool well.
When it does not heat well.
If the remote controller is not
transmitting a signal.
(Remote controller display is
dim or blank.)
REGULAR INSPECTION
PLEASE CHECK THE FOLLOWING POINTS EVERY EITHER HALF YEARLY OR YEARLY. CONTACT YOUR
SALES AGENT SHOULD YOU NEED ANY HELP.
■ The following phenomena do not indicate unit failure.
Hissing or fizzy sounds
Refrigerant flow noise in the pipe or valve sound generated when flow rate is
adjusted.
Squeaking noise
Noise generated when the unit expands or contracts due to temperature
changes.
Rustling noise
Noise generated with the indoor unit fan’s rpm changing such as operation start
times.
Clicking noise Noise of the motorized valve when the unit is switched on.
Changing operation noise
Operation noise changes due to power variations according to room temperature
changes.
Mist emission
Mist is generated as the air within the room is suddenly cooled by conditioned
air.
Steam emitted from the outdoor unit
Water generated during defrosting operation evaporates and steam is emitted.
Odors
Caused as the smells and particles of smoke, food, cosmetics, etc. present in
room air become attached the unit and blown off into the room again.
Perking noise
Noise of the ventilation fan sucking in air present in the drain hose and blowing out
dehumidifying water that had accumulated in the condensed water collector. For
details, consult your sales agent.
– 20 –
Defrosting is underway (as the heating operation is stopped, the microcomputer
checks frost accumulated in the indoor unit and instructs the unit to perform
automatic defrosting if necessary).
This is the noise of the pump thoroughly discharging condensed water
accumulated during cooling or dehumidifying even after operation is stopped.
Actual room temperature may deviate slightly from the remote controller’s temperature
setting depending on the number of people in the room, indoor or outdoor conditions
and influence of other rooms’ conditions when the air conditioner is used for more
than one room at the same time.
The outdoor unit continues to operate
even if operation is stopped.
Does not reach the temperature
setting.
Even if the air conditioner operation is
stopped, noise will be generated from
the indoor unit.
• If the unit still fails to operate
normally after performing the
above inspections, turn the
circuit breaker off and contact
your sales agent immediately.
Contact your sales agent immediately if the
following phenomena should occur:
• The circuit breaker switches off or the fuse blows
frequently.
• The switch operation is not stable.
• Foreign matter or water accidentally enters the unit interior.
• The power cord gets excessively hot or its insulation is torn or
stripped.
• TIMER lamp on the indoor unit display blinks.
As the nature of the failure can be identified by the blinking cycle,
check the blinking cycle before turning off the circuit breaker.
( )
Notes
• In quiet operation or stopping the running, the following phenomena may
occasionally occur, but they are not abnormal for the operation.
(1) Slight flowing noise of refrigerant in the refrigerating cycle.
(2) Slight rubbing noise from the fan casing which is cooled and then gradually
warmed as operation stops.
• The odor will possibly be emitted from the room air conditioner because the
various odor, emitted by smoke, foodstuffs, cosmetics and so on, sticks to it. So
please clean the air filter and the evaporator regularly to reduce the odor.
Note
• Avoid to use the room air conditioner for cooling operation when the outside temperature is below 21°C (70°F).
The recommended maximum and minimum operating temperatures of the hot and cold sides should be as
below:
Cooling Heating
Minimum Maximum Minimum Maximum
Indoor
Dry bulb °C21322027
Wet bulb °C15231219
Outdoor
Dry bulb °C21 43 2 21
Wet bulb °C15 26 1 15
• Please contact your sales agent immediately if the air conditioner still fails to operate normally after the above
inspections. Inform your agent of the model of your unit, production number, date of installation. Please also
inform him regarding the fault.
Please note:
On switching on the equipment, particularly when the room light is dimmed, a slight brightness fluctuation
may occur. This is of no consequence.
The conditions of the local Power Supply Companies are to be observed.
