1.PURSUING COMPACTNESS
(1)Panel size and body volume reduced to 64% of previous models
The width and depth of the panel have been reduced by 19cm respectively,resulting in a compact model which fits smaller environments (like shops) perfectly.
(2)Multi-application panels flexibly adapt to installation conditions.
Space panel and Wide panel may be installed on ceilings with shallow depth using the exiting opening .
2."SMUDGE-FREE", PRECISELY TARGETED AIRFLOW SYSTEM
The new control system regulates airflow to prevent smudging. A projection inside the air passage distributes air evenly over the top and bottom of the vane. Two projections on the air outlet work to prevent cooled air from rising to the celling, and also to stop outside air being dragged into the cooled air stream.
3.AIRFLOW ADJUSTABLE TO ANY INDOOR ENVIRONMENT
Airflow can be adjusted according to celling height and the number of air outlets. "Wide Zoming Flow" creates an optimum airflow for any indoor environment.
4.A FURTHER REFINEMENT OF COMFORT WITH NOISE SUPPRESION
The celling 4-way airflow cassette has a special "silent-design". The "2-Tap"system allows a choice between silent and standard modes according to the height of the cellig. For ordinary residenced which have a low celling, selection of the silent mode will result in remarkable noise reductions.
5.ECONOMICAL AND EASY MAINTENANCE
(1)Push-open grill
Filter clogging is widely recognized as a cause of reduced perfomance, but up until now it has been troublesome to clean filters. With the "push-open grill" the fillter can be smoothly opened out at the push of a button, enabling speedy cleaning.
(2)An unprecedented level of vane-cleaning
The unique airflow system prevents the intake of indoor air. Dewing therefore does not occur, and the vane is flockless. The resulting level of dirt on the vane due to tobacco smoke, dust, etc. is very light,and can be wiped off easily with a neutral detergent.
(3)Long-life filter
This new celling 4-way airflow cassette employs a long life fillter which requires no maintenance for up to 2,500 hours of operation in general office environments. It adds uo to an ideal blend of comfort and low maintenance.

6.COMPACT DIMENSIONS MEAN EASY INSTALLATION
(1)Carefree suspension work with lightweight unit
The new unit weighs in at 20kg and is easy to handle and install. What's more, suspension work is facillitated by compact dimensions ensuring a snug fit.
(2)Smooth installation with "one-direction"bolts
Suspension bolts can be fixes consistently from one direction easing suspension work.
(3)Trouble-free fitting work with slender refrigerant piping
Refrigerant piping has been reduced in size, and pipe-curving work at the installation site can now be completed quickly and economically. In addition, refrigerant and drain piping are set at different corners, which means that flare connections and drain piping heat insulation work can be smoothly and reliably implemented.
(4)Easy-access terminal and control panels for efficient wiring
When performing wiring work, progress can be checked on the power source terminal and control panels simply by removing the electrical parts cover. Address setting can also be done easily from beneath at a convenient angle.
(5)"One-push"to provisionally position front panel
Panel weight has been redused from 7kg to 3.7kg. The previous 3-step process for provisionally positioning the panel has been streamlined, and now a simple "one-push" action at the diagonal corners fixed it into place, resulting in major time-saving.

w The air coverage range is the value up to the position where the air speed is 0.25 m/sec. when air is blown out horizontally from the unit at the Hi notch position.
The coverage range should be used only as a general guideline since it varies according to the size of the room and furniture inside the room.

NOTES: |
|
|
|
|
1.Since the indoor fan motor(MF) is connected with 220V power, using 230, 240V power will require a setting change of the |
||||
dip switch(SW1<I.B>) on the indoor controller board showing fig:1. |
||||
2.Since the indoor transformer(T) is connected with 220V power, if 230, 240V power is used. Change the wiring connection |
||||
showing fig:3. |
|
|
|
|
3.Since the outdoor side electric wiring may change be sure to check the outdoor unit electric wiring for servicing. |
||||

[Emergency operation] If remote controller or microcomputer fails but there is no other trouble,emergency operation is possible by setting dip switch(SW3<I.B>) on the indoor controller board.
[Check items]
(1)Compressor and fan.
(2)Check the trouble position using self diagnostic function.
If the result of self diagnosis indicates protective device such as freeze protection is functioning emergency operation is not possible unless the cause is remove.
(3)Do not attempt emergency operation when drain pump fails(drain overflows).
(4)Emergency operation will be a continuous operation mode due to power ON/OFF. (ON/OFF with the remote controller is not possible.)
[Emergency operation procedure]
(1)Set the dip switch(SW3<I.B>) on the indoor controller board to 1 , 2 on and 3 off for cooling (2)Turn on the outdoor unit side circuit breaker, then the indoor unit side circuit breaker.
(3)During emergency operation indoor fan runs at high speed but auto-vane does not work. (4)Thermostat will not function.
(5)Emergency cooling should be limited to 10 hours maximam. (the indoor unit heat exchanger may freeze.)
