1FEATURES
1. ADVANCED REMOTE CONTROLLER
(1) Ultra-thin 12mm (1/2”) remote controller
The streamelined, square controller is designed to blend with any inte-
rior. Also, the sophisticated microprocessor allows you to easily carry
out a wide range of operations.
(2) Attractive LED display
Every operation condition is indicated on the LED display.
(3) Simultaneous display of set temperature and room temperature
The set temperature is indicated by continuous light and the room tem-
perature is indicated by a flashing light. In this way, accurate tempera-
ture conditions are always available at a glance and fine temperature
regulation is possible.
(4) Convenient 12-hour ON-OFF timer
The timer switches on and off automatically at the times you set. Once
the timer is set, the remaining time is shown on the LED display.
(5) Self-diagnostic feature indicates faults instantly
If a problem occurs, the unit will stop operating and the temperature
display will change to a self-diagnosis indicator, which shows the loca-
tion of the trouble.
(6) Useful memory feature for storing instructions
The previous set value is memorized so that constant temperature control can be achived. For example, if a power fail-
ure occurs, the temperature will not have to be readjusted afterwards.
(7) Cables between remote controller and indoor unit
The polar, 12-core type remote controller cables makes installation simple and troublefree. Also, the cables can be
extended up to 50m. (optional)

1Removed the knockout work by separating the piping space
from the air outlet for efficiency of the piping work.
wKnockout work is needed for the top part. When optional
drain-up machine is installed, the refrigerant pipe exits out
from the top.
2Improved the flexibility by making it possible for drainage
pipe to exit not only from the right side back but also from
the left side back.
wPlease move the rubber plug for the unit to the right joint
when drainage pipe exits from the left side.
1. AIR OUTLET
New PC series models have 1 air outlet (auto vane switching of horizontal air flow / down flow by switched by auto vane)
instead of 2 (horizontal, and down flows).
2. EASY TO CLEAN ; FLOCKLESS VANE
With our original air current control mechanism, a flockless vane is
newly adapted.
The flockless vane prevents the condensation on the vane.
By changing the vane to the flockless type, the unit can be cleaned
much easier with mild household detergent.
3. NEW MATERIALS FOR BETTER OIL RESISTANCE
We have changed the materials of grill, filer, fan and fan casing from ABS to P.P. (polypropylene) for better oil resistance. As
a result, oil crazing is cut in half.
4. SIMPLIFIED INSTALLATION WORK (DIRECT SUSPENDING METHOD)
Simplified the installation work by changing the suspending method to the direct suspending method (suspending the unit
directly from the suspension fixture).
In this way, the unit can be attached to the suspension fixture without removing the installation parts off (Only the side cover
is removed). This method is much simpler than the ¨One-time installation method¨.
5. IMPROVING EFFICIENCY OF PIPING WORK
New PC series models have 1 air outlet (auto vane switching of horizontal air flow / down flow by switched by auto vane)
instead of 2 (horizontal, and down flows).

6. QUITENESS ; 43dB : PC-3GJA1(HIGH NOTCH)
Quiteness of the New PC series product is significant. It is because we have adapted the new shape air outlet and changed
the air coures.
7. EASY MAINTENANCE ; NO MAINTENANCE NECESSARY FOR 2500 HOURS
The new long-life air filter can be used continuously 2500 hours without maintenance (at general office situation).

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 Hi notch position.
The coverage range should be used as a general guide-
line since it varies according to the size of the room and
furniture inside the room.
The unit of pressure has been changed to MPa based on SI(International System of unit) in accordance with I.S.O.(International
Organization for Standardization).
The conversion factor is : 1(MPa•G)=10.2(kgf / FF•G)

[Emergemcy operation procedure]
(2) Turn on outdoor unit side circuit breaker, then indoor unit side circuit breaker in this order.
(3) During emergency operation, indoor fan runs at high speed but automatic vane remains stop.
(4) If vane closed, open the vane by hand slowly.
(5) Thermostat will not function.
(6) Emergency cooling should be limited to 10 hours maximum (The Indoor unit heat exchanger may freeze).
(7) If the ,microcomputer doctor detects the abnomality of the drain-up machine during cool mode. do not execute emergency operation (It causes drain overflow).
3. Since the outdoor side electric wiring may change be sure to check the outdoor unit electric wiring for servicing.
4. Symbols used in wiring diagram above are. : Connector , : Terminal block
5. 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 abnomality using self diagnostic function. When the result of self diagnosis indicates protective device such as freeze protection, emergency operation is not possible
unless the cause is removed.
(3)Emergency operation will be continuous operation mode due to power ON/OFF (ON/OFF with remote controller is not possible).
[Emergency operation procedure]
(1)Set the dip switch(SW3<I.B>) on the indoor controller board to1 2 onand 3off for cooling.
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
as shown in fig : w1.
2. Since the indoor transformer (T) is connected with 220V power, if 230, 240V power used. Change the wiring connection showing fig : W2.
