FEATURES

1. TOTALLY INVISIBLE INDOOR UNIT BEHIND THE CEILING

The totally hidden indoor unit that lies above the ceiling surface enables you to utilize full floor space while allowing for
flexible interior design. This new feature is recommended for stores and offices where the user's own imagination is
allowed to be incorporated.

2. MOST SUITABLE FOR SIMULTANEOUS TWO ROOM AIR CONDITIONING

Using air ducts for cooling airflow that matches the structure and purpose of the room, enables you to provide two air
outlets for simultaneous cooling of two rooms.

3. HIGH EXTERNAL STATIC PRESSURE (OPTION MOTOR)

The exceptional external static pressure of 130Pa allows long ducts to be used more extensively to achieve convenient
location of indoor units. (STD:70Pa)

4. DRAIN WATER LIFT-UP MECHANISM (OPTION KIT)

This allows more versatility when selecting drain piping layouts.

PART NAMES AND FUNCTIONS

5. ADVANCED MICROPROCESSOR CONTROL

(1) Ultra - thin 12mm(1/2" )remote controller.
(2) Attractive LED display .

Every operation condition is indicated on the LED display.
(3) Simultaneous display of set temperature and room temperature.
(4) Convenient 12 - hour ON-OFF timer.

This convenient timer allows the unit to be switched on and off automatically,at the time you set. Once the timer is

set,the remaining time is shown on the LED display..
(5) Self - diagnostic function indicates problems instantly on remote controller.
(6) The useful memory feature can store instructions.

The previous set value is memorized so that constant temperature control can be obtained. For example,if a power

failure occurs, this feature will conveniently memorize the previous temperature and reset accordingly.
(7) There is a polar 12 core - conductor cable between the remote controller and indoor board.The cable can be extended

up to 50m.(option)
