ATTENTION
■
About batteries
• When replacing the batteries, use batteries of the same type, and replace the two old batteries together.
• When the system is not used for a long time, take the batteries out.
• The batteries will last for approximately one year. If the remote controller display begins to
fade and the degradation of reception performance occurs within a year, however, replace
both two batteries with new size AAA alkaline batteries.
• The attached batteries are provided for the initial use of the system.
The usable period of the batteries may be short depending on the manufactured date of the air conditioner.
■
About remote controller
• Never expose the remote controller to direct sunlight.
• Dust on the signal transmitter or receiver will reduce the sensitivity. Wipe off dust with soft cloth.
• Signal communication may be disabled if an electronic-starter-type fluorescent lamp (such
as inverter-type lamps) is in the room. Consult the shop if that is the case.
• If the remote controller signals happen to operate another appliance, move that appliance
to somewhere else, or consult the shop.

■Turn the breaker ON
• Turning ON the breaker opens once and closes the flaps. (This is a normal procedure.)
■Checks on Remote Controller Settings
• This remote controller is common to the heat pump model
and cooling only model. Use the dipswitches on the remote
controller to set the heat pump model or cooling only model.
• Refer to the following explanation and make the setting as
shown in the illustration.
• For customers of Heat pump model: Set to H/P
• For customers of Cooling-only model: Set to C/O
NOTE
■
Tips for saving energy
• Be careful not to cool (heat) the room too much.
Keeping the temperature setting at a moderate level helps save energy.
• Cover windows with a blind or a curtain.
Blocking sunlight and air from outdoors increases the cooling (heating) effect.
• Clogged air filters cause inefficient operation and waste energy.
Clean them once in about every two weeks.
■
Please note
• The air conditioner always consumes 15-35 watts of electricity even while it is not operating.
•
If you are not going to use the air conditioner for a long period, for example in spring or autumn, turn the breaker OFF.
• Use the air conditioner in the following conditions.
•The operation of the system outside the above humidity or temperature range may cause a
safety device to disable the system.

■
Note on HEAT operation
• Since this air conditioner heats the room by taking heat from outdoor air to indoors, the heating
capacity becomes smaller in lower outdoor temperatures. If the heating effect is insufficient, it
is recommended to use another heating appliance in combination with the air conditioner.
• The heat pump system heats the room by circulating hot air around all parts of the room.
After the start of heating operation, it takes some time before the room gets warmer.
• In heating operation, frost may occur on the outdoor unit and lower the heating capacity. In
that case, the system switches into defrosting operation to take away the frost.
• During defrosting operation, hot air does not flow out of indoor unit.
• A pinging sound may be heard during defrosting operation, which, however does not mean
that the air conditioner has failures.
■
Note on COOL operation
• This air conditioner cools the room by blowing the hot air in the room outside, so if the
outside temperature is high, the performance of the air conditioner drops.
■
Note on DRY operation
• The computer chip works to rid the room of humidity while maintaining the temperature as
much as possible. It automatically controls temperature and airflow rate, so manual
adjustment of these functions is unavailable.
■
Note on AUTO operation
• In AUTO operation, the system selects a temperature setting and an appropriate operation
mode (COOL or HEAT) based on the room temperature at the start of the operation.
• The system automatically reselects setting at a regular interval to bring the room
temperature to user-setting level.
• If you do not like AUTO operation, manually change the set temperature.
■
Note on airflow rate setting
• At smaller airflow rates, the cooling (heating) effect is also smaller.

COMFORT AIRFLOW and
INTELLIGENT EYE Operation
Notes on “INTELLIGENT EYE Operation”
“INTELLIGENT EYE” is useful for Energy Saving
■To combine “COMFORT AIRFLOW Operation” and
“INTELLIGENT EYE Operation”
CAUTION
• While the air conditioner is in INTELLIGENT EYE operation, the louvers will adjust the
airflow direction if there are people in the sensing areas of the INTELLIGENT EYE so that
the leftward or rightward airflow will not be directed to the people.
If no people are detected in either area 1 or 2 in 20 minutes, the air conditioner will go into
energy-saving mode with the set temperature shifted by 2°C.
The air conditioner may go into energy-saving operation though there are people in the
areas. This may occur depending on the clothes of the people or if there are no movements
of the people in the areas.
•
The airflow direction from the louvers will be leftward if there are people in both areas 1 and 2 or if there
is a person right in front of the sensors because the sensors on the both sides will detect the person.
•
Due to the position of the sensor, people will be exposed to the wind of the indoor unit if they
are close to the front side of the indoor unit.
If there are people close to the front side of the indoor unit or in both areas, it is recommended
to use the COMFORT AIRFLOW and INTELLIGENT EYE functions simultaneously. When
both of them are in use, the air conditioner will not direct the airflow towards the people.
• Sensor may not detect moving objects further than 5m away. (Check the application range)
• Sensor detection sensitivity changes according to indoor unit location, the speed of
passersby, temperature range, etc.
• The sensor also mistakenly detects pets, sunlight, fluttering curtains and light reflected off of
mirrors as passersby.
• NIGHT SET MODE (page 20.) will not go on during use of INTELLIGENT EYE operation.
■
Energy saving operation
• Change the temperature –2°C in heating / +2°C in cooling / +2°C in dry mode from set temperature.
• Decrease the airflow rate slightly in FAN mode only. If no presence detected in the room for
20 minutes.
• The air conditioner can go into operation with the COMFORT AIRFLOW and INTELLIGENT
EYE functions combined.
The flaps adjust the airflow direction upward (while in cooling operation) and downward
(while in heating operation), during which the sensors of the INTELLIGENT EYE are working
to detect the movement of people. When the sensors detect people, the louvers will direct
the airflow such it will not be blown directly on them. If there are no people, the air
conditioner will go into energy-saving operation in 20 minutes.
• Do not place large objects near the sensor.
Also keep heating units or humidifiers outside the sensor’s detection area. This sensor can
detect undesirable objects.
•
Do not hit or violently push the INTELLIGENT EYE sensor. This can lead to damage and malfunction.
