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.. 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. Air outlet duct Air intake duct air outlet air outlet air intake 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.

3 5. ADVANCED MICROPROCESSOR CONTROL () Ultra - thin mm(/" )remote controller. () Attractive LED display. Every operation condition is indicated on the LED display. (3) Simultaneous display of set temperature and room temperature. (4) Convenient - 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 core - conductor cable between the remote controller and indoor board.the cable can be extended up to 50m.(option) PART NAMES AND FUNCTIONS Indoor Unit Air outlet or Air intake (sucks the air inside the room into the unit)

4 Remote controller Settings remain in effect until changed. Air conditioner can be operated by simply pushing ON/OFF button once settings have been made. Operation buttons (Example display readings are for explanations only ;actual display readings will differ. 3

28 OPTIONAL PARTS. REFRIGERANT PIPES Part No. PAC-05FFS-E PAC-07FFS-E PAC-0FFS-E PAC-5FFS-E Pipe length 5m 7m 0m 5m Pipe size OD Connection method Liquid:/ø9.5 Gas:/ø5.88 Indoor unit:flared Outdoor unit:flared Note.How to connect refrigerant pipes. Factory supplied optional piping contains refrigerant at above atmospheric pressure. As long as the connection takes no more than 5 minutes, no air will enter, and there will be no need for air purging. Remove the blind caps and make the connections within 5 minutes. After the connections for the indoor and outdoor units are made, open the stop valve on the outdoor unit to allow refrigerant gas to flow. If piping length exceeds 5m, an additional charge of refrigerant is needed. Note.The following main parts are contained in the optional refrigerant piping kit. Heat insulating cover, vinyl tapes, nipples, sleeve and flange(for wall hole), connecting cables.. REMOTE CONTROLLER EXTENSION CABLE When installing the remote controller at a distance from the air conditioner, use the designated extension cable with connector. Part No. PAC-905EC PAC-906EC PAC-98EC PAC-99EC Length m 0m 30m 50m 3. TIMER When using a program timer, a program timer adapter (PAC-85AD)is also needed.

Each unit can be set for unit ON, unit OFF, or setback operation. () Setback operation(pac-sk65pt) Set back operation is useful for reducing running costs. e.g.at a hotel with a 4-hour system 8:00~3:00 Cooling operation with set temperature at 6 C 3:00~8:00 Setback operation with degrees of setback As shown in the chart on the right, the set temperature rises degrees automatically during the setback operation. When the setback operation ends, normal operation will begin. (3) Weekly timer function Daily timer function can apply to each day of the week. 7

29 3-3 HOW to connect program timer () Install the program timer next to the remote controller the same way as the remote controller is installed. () Connect the program timer and the remote controller with a 6-wire cable as shown in the figure below. NOTE: While the program timer is connected to the remote controller, the 4 hour ON/OFF timer on the remote controller will not operate. 3-4 Names and functions <PAC-SK65PTA> 8

30 4. CENTRALIZED REMOTE CONTROLLER Allows individual or combined control of up to 6 units. 4- Dimensions Unit:mm Functions "ENGAGED" indicator When this indicator is lit, transmisson is in progress and all swiches are inoperative. DUAL / CENTRAL switch This change-over switch governs the operation of the accessory remote controller. "DUAL" Instructions from both the accessory remote controller and the centralized remote controller are valid. (Priority given to the last instruction received.) "CENTRAL" ON / OFF switching by the accessory remote controller is invalidate. Operation is controlled by the centralized remote controller only. Inital setting is "DUAL" LCD Matrix display This display indicates the operational status of all connected units either by steady lighting or by flashing. POWER ON / OFF switch Operation ON / OFF switch. BACK AHEAD buttons These buttons are used to designate the attached unit (s). (They designate the unit to be centrally controlled.) When group "00" is designated ; collective ON/OFF instruction is sent to all units. When group "0" - "6" is designated ; ON/OFF instruction is sent only to the designated units. ACTIVE / BYPASS switch This change-over switch is for the program timer. (It selects the timer operation on the program timer.) Use "BYPASS" when a program timer is not connected. "ACTIVE" The switch turns ON/OFF commands given from the program timer automatically. "BYPASS" ON/OFF Operation is controlled by the centralized remote controller only. Initial setting is "BYPASS". Independent "DUAL / CENTRAL" and "ACTIVE / BYPASS" setting of all the groups is prossible. When the power supply to the centralized remote controller is cut due to power failure, all settings will return to the original "DUAL" and "BYPASS". 9
