1.PURSUING CONPACTNESS

(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. Aprojection 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
anoptimum 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 fillter

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 (9kg lighter than the previous model) 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. Adress 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.

7.ADVANCED MICROPROCESSOR [PAR-F25MA]

(1)Easy to use microprocessor

1)Ultra-thin remote controller

The streamlind,square controller is designed to blend well with
any interior.Also,the sophisticated microprocessor allows you to
easily carry out a wide range of operations.

2)Attractive liquid crystal display(LCD)

The unit´s operation mode,set temperature,room
temperature,timer setting,fan speed,louver oper-ation,and air flow
direction are displayed on the remote controller´s easy-to-read
Liquid Crystal Dis-play(LCD).

3)Convenient 24-hour ON-OFF timer

The timer switches Mr.SLIM on and off automati-cally at the time
you set. Once the timer is set,the remaining time is shown on the
LCD

SAFETY PRECAUTION

Cautions for devices that use R407C refrigerant.

· Do not use the existing refrigerant piping.

-The old refrigerant and refrigerator oil in the existing piping contains a large amount of chlorine which may cause the
refrigerator oil of the new unit to deteriorate.

· Use “low residual oil piping”.

-If there is a large amount of residual oil (hydraulic oil, etc.) inside the piping and joints, deterioration of the refrigerator oil
will result.

· Store the piping to be used during installation indoors and keep both ends of the piping sealed until just before
brazing. (Store elbows and other joints in a plastic bag.)

-If dust, dirt, or water enters the refrigerant cycle, deterioration of the oil and compressor trouble may result.

· Use Suniso 4GS or 3GS (small amount) as the refrigerator oil to coat flares and flange connection parts.

-The refrigerator oil used with the air conditioner is highly hygroscopic. If it is used, water may be mixed in and deterioration

of the refrigerator oil may result.

· Use liquid refrigerant to seal the system.

-If gas refrigerant is used to seal the system, the composition of the refrigerant in the cylinder will change and performance

may drop.

· Do not use a refrigerant other than R407.

-If another refrigerant (R22, etc.) is used, the chlorine in the refrigerant may cause the refrigerator oil to deteriorate.

· Use a vacuum pump with a reverse flow check valve.

-The vacuum pump oil may flow back into the refrigerant cycle and cause the refrigerator oil to deteriorate.

The output pulse shifts in above order.
❈ 1. When linear expasion valve operation stops, all output phase

become OFF.

2. At phase interruption or when phase does not shift in order,
motor does not rotate smoothly and motor will locks and vibrates.

❈ When the switch is turned on, 2200 pulse opening valve signal

will be send till it goes to

A point in order to define the valve

position.

When the valve move smoothly, there is no noise or vibration
occurring from the linear expansion valve : however, when the
pulse number moves from E to A or when the valve is locked,
more noise can be heard than normal situation.

❈ Noise can be detected by placing the ear against the screw

driver handle while putting the screw driver to the linear
expansion valve.

is the sign of the abnormality.
