FEATURES AND FUNCTIONSFEATURES AND FUNCTIONS
INVERTER
At the start of operation, large amount of power is used to bring the room quickly to the desired temperature. Afterwards, the unit automatically switches to a low power setting for eco­nomic and comfortable operation.
WIRELESS REMOTE CONTROLLER
The Wireless Remote Controller allows convenient control of air conditioner operation.
ECONOMY OPERATION
When ECONOMY operation mode is operated, the room tem­perature will be little higher than the set-temp under cooling mode and lower than set-temp under heating mode. Therefore, the ECONOMY mode is able to save more energy than other normal mode.
AUTO CHANGEOVER
The operation mode (cooling, dry, heating) is switched auto­matically to maintain the set temperature, and the temperature is kept constant at all times.
MINIMUM HEAT OPERATION
The room temperature can be maintained at 50°F so as to pre­vent the room temperature from falling too far.
PROGRAM TIMER
The program timer allows you to integrate OFF timer and ON timer operations in a single sequence. The sequence can in­volve 1 transition from OFF timer to ON timer, or from ON timer to OFF timer, within a 24 hour period.
SLEEP TIMER
When the SLEEP button is pressed during Heating mode, the air conditioner’s thermostat setting is gradually lowered during the period of operation; during cooling mode, the thermostat setting is gradually raised during the period of operation. When the set time is reached, the unit automatically turns off.
OMNI-DIRECTIONAL AIRFLOW (SWING OPERATION)
3-dimensional control over air direction swing is possible through dual use of both an UP/DOWN air direction swing and RIGHT/LEFT air direction swing. Since UP/DOWN air direction fl aps operate au­tomatically according to the operating mode of the unit, it is possible to set air direction based on the operating mode.
REMOVABLE INTAKE GRILLE
The indoor unit’s INTAKE GRILLE can be removed for easy cleaning and maintenance.
MILDEW-RESISTANT FILTER
The AIR FILTER has been treated to resist mildew growth, thus allowing cleaner use and easier care.
SUPER QUIET OPERATION
When the FAN button is used to select QUIET, the unit begins super-quiet operation; the indoor unit’s airflow is reduced to produce quieter operation.
POLYPHENOL CATECHIN AIR CLEANING FILTER
The polyphenol catechin air cleaning fi lter uses static electric­ity to clean fi ne particles and dust in the air such as tobacco smoke and plant pollen that are too small to see. The fi lter contains catechin, which is highly effective against various bacteria by suppressing the growth of the bacteria ad­sorbed to the fi lter. Note that when the air cleaning fi lter is installed, the amount of air produced decreases, causing a slight decrease in the indoor unit’s performance.
NEGATIVE AIR IONS DEODORIZING FILTER
It comprises pottery super micro particles which can produce negative air ions having the effect of deodorizing and can ab­sorb and remit the peculiar smell at home.
HORIZONTAL AIRFLOW: COOLING/ DOWNWARD AIRFLOW: HEATING
For cooling, use horizontal airfl ow so the cool air does not blow directly on the occupants in the room. For heating, use down­ward airfl ow to send powerful, warm air to the fl oor and create a comfortable environment.

DANGER!
Never place fi ngers or foreign objects inside
the outlet ports, since the internal fan oper­ates at high speed and could cause per­sonal injury.
Always use the Remote Controller’s
SET button to adjust the vertical airfl ow louvers. Attempting to move them man­ually could result in improper operation; in this case, stop operation and restart. The louvers should begin to operate properly again.
During use of the Cooling and Dry
modes, do not set the Airfl ow Direction Louvers in the Heating range (4 - 6) for long periods of time, since water va­por may condense near the outlet lou­vers and drops of water may drip from the air conditioner. During the Cooling and Dry modes, if the Airfl ow Direction Louvers are left in the heating range for more than 20 minutes, they will auto­matically return to position 3.
When used in a room with infants, chil-
dren, elderly or sick persons, the air direction and room temperature should be considered carefully when making settings.

OPERATING TIPS
Operation and Performance
Heating Performance
This air conditioner operates on the heat-pump principle,
absorbing heat from outdoor air and transferring that heat to indoor unit. As a result, the operating performance is reduced as outdoor air temperature drops. If you feel that insufficient heating performance is being produced, we recommend you use this air conditioner in conjunction with another kind of heating appliance.
Heat-pump air conditioners heat your entire room by recir-
culating air throughout the room, with the result that some time may be required after fi rst starting the air conditioner until the room is heated.
Microcomputer-controlled Automatic Defrosting
When using the Heating mode under conditions of low out-
door temperature and high humidity, frost may form on the outdoor unit, resulting in reduced operating performance.
In order to prevent this kind of reduced performance, this air
conditioner is equipped with a Microcomputer-controlled Au­tomatic Defrosting function. If frost forms, the air conditioner will temporarily stop, and the defrosting circuit will operate briefl y (for about 7-15 minutes).
During Automatic Defrosting operation, the OPERATION
Indicator Lamp (green) will fl ash.
After heating operation stops, if frost forms on the outdoor
unit, the unit will start Automatic Defrosting operation. At this time, the outdoor unit will automatically stop after oper­ating for a few minutes.

OPERATING TIPS
AUTO Restart
In Event of Power Interruption
If a power interruption occurs during TIMER operation, the
The power supply to the air conditioner is stopped by a
power interruption. The air conditioner will then restart auto­matically in its previous mode when the power is restored.
Multi-type Air conditioner
This indoor unit can be connected to a multi-type outdoor unit. The multi-type air conditioner allows multiple indoor units to be oper­ated in multiple locations. The indoor units may be operated simultaneously, in accordance with their respective output.
Simultaneous Use of Multiple Units
● When using a multi-type air conditioner, the multiple indoor
units can be operated simultaneously, but when 2 or more indoor units of the same group are operated simultane­ously, the heating and cooling effi ciency will be less than when a single indoor unit is used alone. Accordingly, when you wish to use more than 1 indoor unit for cooling at the same time, the use should be concentrated at night and other times when less output is required. In the same way, when multiple units are used simultaneously for heating, it is recommended that they be used in conjunction with other auxiliary space heaters, as required.
● Seasonal and outdoor temperature conditions, the struc-
ture of the rooms and the number of persons present may also result in differences of operating effi ciency. We rec­ommend that you try various operating patterns in order to confi rm the level of heating and cooling output provided by your units, and use the units in the way that best matches your family’s lifestyle.
● If you discover that 1 or more units delivers a low level
of cooling or heating during simultaneous operation, we recommend that you stop simultaneous operation of the multiple units.
● Operation cannot be done in the following different operat-
ing modes.
If the indoor unit is instructed to do an operating mode that
it cannot perform, the OPERATION indicator lamp (green) on the indoor unit will fl ash (1 second on, 1 second off) and the unit will go into the standby mode.
Heating mode and cooling mode (or dry mode) Heating mode and fan mode
timer will be reset and the indoor unit will begin (or stop) op­eration at the new time setting. In the event that this kind of timer fault occurs, the TIMER Indicator Lamp will fl ash (see Page. 3).
Use of other electrical appliances (electric shaver, etc.) or
nearby use of a wireless radio transmitter may cause the air conditioner to malfunction. In this event, temporarily turn off the circuit breaker, turn it on and then use the Remote Con­troller to resume operation.
Operation can be done in the following different operating
modes. Cooling mode and dry mode Cooling mode and fan mode Dry mode and fan mode
The operating mode (heating mode or cooling (dry) mode)
of the outdoor unit will be determined by the operating
mode of the indoor unit that was operated fi rst. If the in-
door unit was started in fan mode, the operating mode of
the outdoor unit will not be determined.
For example, if indoor unit (A) was started in fan mode and
then indoor unit (B) was then operated in heating mode,
indoor unit (A) would temporarily start operation in fan
mode but when indoor unit (B) started operating in heating
mode, the OPERATION indicator lamp (green) for indoor
unit (A) would begin to fl ash (1 second on, 1 second off)
and it would go into standby mode. Indoor unit (B) would
continue to operate in heating mode.
Notice
During use of the heating mode, the outdoor unit will occa-
sionally commence the defrost operation for brief periods. During the defrosting operation, if the user sets the indoor unit for heating again, the defrosting mode will continue, and the heating operation will begin after completion of defrosting, with the result that some time may be required before warm air is emitted.
During use of the heating mode, the top of the indoor unit
may become warm, but this is due to the fact that cool-
ant is circulated through the indoor unit even when it is
stopped; it is not a malfunction.
