1. TOTALLY INVISIBLE INDOOR UNIT BEHINDTHE 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

The exceptional external static pressure of 70Pa allows long ducts to be used more extensively to achieve convenient

location of indoor units. (The factory setting is 30Pa.)

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

This allows more versatility when selecting drain piping layouts.

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)
