INFORMATION
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 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.
PROHIBITION
CAPABILITIES
Do not use a stove or
any other high temperature devices in proximity
to the indoor unit.
• 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.
• During heating operation, the “OPERATION” lamp on the indoor unit indicators may blink with no air emitted for
a while.
• If you feel cold wind during heating 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), (SILENT) settings, the unit’s cooling capacity will lower slightly.
• With the
(LOW),
(SILENT) settings, the unit’s fan speed of heating operation will vary with the operating
conditions.
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
(SILENT) regardless of the preset speed. The remote

– 34 –
Automatic Two Way Air Exchange Operation
• The Dirt Sensor detects cigarette smoke, sprays (pesticides), alcohol, etc.
• The Dirt Sensor may also respond to sudden temperature changes when the cooling/heating operation starts and
sudden changes in airflow when doors open and close.
• The automatic two way air exchange can be configured for two weeks at one time. The
(AUTOMATIC TWO WAY
AIR EXCHANGE) is configured for two weeks after it is set with the remote controller.
• Even the air in the room is dirty after the automatic two way air exchange operation has been configured, the exhaust
operation does not perform for 5 minutes.
• In the case the automatic two way air exchange operation performs during the air conditioning operation, the exhaust
or fresh air in operates in addition to the air conditioning.
• Once the dirt sensor detects the dirt and starts exhaust operation, even you open the window after that the exhaust
operates for at least 20 minutes and then operates the fresh air in.
• The two way air exchange operation does not perform depending on the room temperature/outside air temperature.
Changing the Sensitivity of the Dirt Sensor
■ There are 7 levels of sensitivity
1
Press the button while the operation is stopped.
(Please operate either the fresh air in or the exhaust. Select the fan speed “HI”, “MED” or
“LOW”.)
2
The sensitivity can be selected with the Room Temperature button.
sensitivity increase/sensitivity decrease
• Increasing the sensitivity by one level displays “+1”.
• Decreasing the sensitivity by one level displays “–1”.
• The configuration range has 7 levels: +3 - –3.
• The +3 - –3 display will turn off after about 10 seconds.
3
Please stop the operation with the button.
Self Clean Operation (Page 19)
• By setting Self Clean operation, it automatically starts self clean operation after stopping the cooling and dehumidifying
operations. First, wash the odor components attached to the indoor heat exchanger due to the “FAN” operation (combined
with the exhaust). Next, “HEATING” (combined with the exhaust), “ONLY EXHAUST” and “FAN” operation (combined
with the exhaust) are performed to suppress the outbreak of mold in the indoor unit.
• If the outside air temperature is low, the cooling and dehumidifying may not operate.
• If the ON-TIMER has been configured, the Self Clean operation does not perform two hours before the configured
time.
• If the operation is stopped in the following conditions, the Self Clean operation does not perform. (Heating and Air
purifying operations, stopped by pressing OFF-TIMER or SLEEP TIMER.)
Timer Settings
• If the remote controller never receive the signal when timer is set, it does not start to operate even when reaching the
set time. Please confirm the timer setting by the “beep” sound and the “Timer” lamp on the indoor unit.
• When the dehumidifying is operated while the timer is configured, the timer settings will disappear from the LCD, but
the setting is not canceled. When the dehumidifying operation is stopped, the timer settings will display again.

■ The following phenomena do not indicate unit failure.
<Operation start>
The unit is preparing to blow warm air. Please wait.
<In operation>
The outdoor unit is defrosting. Please wait.
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.
During heating, the operation indicator
blinks and air blow stops
– 36 –
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.
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.
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).
Shows preheating or defrosting operation is underway.
As the protective circuit or preheat sensor operates when unit operation is stopped
during preheating and then restarted, or when operation mode is switched from
cooling to heating, the lamp continues to blink.
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
when the air conditioner is used for more than one room at the same time.
• If the unit still fails to operate
normally after performing the
above inspections, turn the circuit
breaker off and contact your sales
agent immediately.
• 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.
( )
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 or FILTER lamp on the indoor unit indicators 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.
The outdoor unit continues to operate
even if operation is stopped.
The OPERATION lamp is blinking.
Does not reach the temperature
setting.
Please note:
On switching on the equipment, particularly when the room light is dimmed, a slight brightness fluctuation may
