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

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)

NOTES
1. Since the outdoor side electric wiring may change be sure
to check the outdoor unit electric wiring for servicing.
2. Symbols used in circuit diagram above are, :Terminal block,
:connector.
3. Emergency operation
If a trouble occurs with either the remote controller or
the indoor microcomputer and no other trouble exists,emergency operation for cooling can be performed by changing
the setting of dip switch (SW3<I.B>) on the indoor controller
board (emergency dry operation is not possible).

(1) Make sure that no other trouble exists with the outdoor unit.
Trouble with the outdoor unit prevents emergency operation.
(If any trouble exists with the outdoor unit,the trouble
location will be displayed on the remote controller and
the trouble position will be shown on the outdoor controller board LED.See electric circuit diagram of the outdoor
unit for details.)
(2) Make sure that there is no trouble with the indoor fan.
Emergency operation will be a continuous run with the power
ON/OFF(ON/OFFwith 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.
(3) During emergency operation indoor fan runs at High speed.
(4) Thermostat will not function.Cold air blows out for defrosting during heating thus do not operate de frosting for
a long time.
(5) Emergency cooling should be limited to 10 hours maximum(the
indoor unit heat exchanger may freeze).

Note 1.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 2.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.
2. REMOTE CONTROLLER EXTENSION CABLE
When installing the remote controller at a distance from the air conditioner, use the designated extension cable with
connector.

(1) Daily timer function
Daily timer can be set in 30 minute units for up to 24 hours.
Each unit can be set for unit ON, unit OFF, or setback operation.
(2) Setback operation(PAC-SK65PT)
Set back operation is useful for reducing running costs.
e.g.AT a hotel with a 24-hour system
8:00~23:00 Cooling operation with set temperature at 26 ˚C
23:00~8:00 Setback operation with 2 degrees of setback
As shown in the chart on the right, the set temperature rises 2
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.

3-3 HOW to connect program timer
(1) Install the program timer next to the remote controller the same way as the remote controller is installed.
(2) 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 24 hour ON/OFF timer on the remote controller will not
operate.

4-2 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 "01" - "16" 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".

4-3 Connection method
(1) Connection in the power supply cord.
1. Connect the power supply cord to the power supply terminal-block and fix in-place with a tie-wrap. Connect a single
phase 200V AC(220, 230, 240V)to AN .
As E is the GND terminal,be sure to ground the earth wire.
2. Connect the transmission line to the transmission terminal-block and fix it in-place with a tie-wrap. Use a ø1.6
(AWG14)or above two-wire cable for the transmission line.
CAUTION: Never connect the power supply cord to the transmission terminal-block.
