1. AIR OUTLET
New PCH series models have 1 air outlet (auto vane swit hing of horizontal air flow / down flow by swit hed by auto vane)
instead of 2 (horizontal,and down flows).
2. EASY TO CLEAN ; FLOCKLESS VANE
With our original air urrent ontrol me hanism, a flo kless vane is
newly adapted.
The flo kless vane prevents the ondensation on the vane.
By hanging the vane to the flo kless type, the unit an be leaned
mu h easier with mild household detergent.
3. NEW MATERIALS FOR BETTER OIL RESISTANCE
We have hanged the materials of grill, filer, fan and fan asing from ABS to P.P. (polypropylene) for better oil
resistan e. As a result, oil razing is ut in haif.
4. SIMPLIFIED INSTALLATION WORK (DIRECT SUSPENDING METHOD)
Simplified the installation work by hanging the suspending method to the dire t suspending method (suspending
the unit dire tly from the suspension fixture).
In this way, the unit an be atta hed to the suspension fixture without removing the installation parts off (Only the
side over is removed). This method is mu h simpler than the “One-time installation method”.
5. IMPROVING EFFICIENCY OF PIPING WORK
1Removed the kno kout work by separating the piping
spa e from the air outlet for effi ien y of the piping work.
wKno kout work is needed for the top part. When
optional drain-up ma hine is installed, the refrigerant
pipe exits out from the top.
wPlease move the rubber plug for the unit to the right joint
when drainage pipe exits from the left side.
2Improved the flexbility by making it possible for
drainage pipe to exit not only from the right side
ba k but also from the left side ba k.
Unifies the air speed
with the vane.
Sending the air to the upper
area of the vane
Prevents the air omes from

(2) Turn on the outdoor unit side ir uit breaker, then indoor unit side ir uit breaker in this order.
(3) During emergen y operation indoor fan runs at high speed but automati vane remains stop.
(4) If vane losed, open the vane by hand slowly.
(5) Thermostat will not fun tion. Cold air belows out for defrosting during heating thus do not operate defrosting for a long time.
(6) Emergen y ooling should be limited to 10 hours maximum.
(The indoor unit heat ex hanger may freeze).
(7) If the mi ro omputer do tor dete ts the abnormality of the drain-up ma hine during ooling mode, do not exe ute emergen y
operation.(If auses drain overflow)
NOTES :
1. Sin e the indoor fan motor (MF 1.2) is onne ted with
230~240V power. IF 220V power is used. hange the dip
swit h (SWS<1.B>)on the indoor ontroller board showing
fig:w1.
2. Sin e the indoor transformer (T)is onne ted with
240Vpower.if 220.230V power is used. Change the wiring
onne tion showing fig:w2.
3. Sin e the outdoor side ele tri wiring may hange be sure to he k the outdoor unit ele tri wiring for servi ing.
4. Indoor and outdoor onne ting wires are made with polarities. make wiring mat hing terminal numbers.
5. Symbols used in wiring diagram above are.
: Conne tor, /
/: Terminal blo k.
6. Emergen y operation
If remote ontroller or mi ro omputer fails but there is no other truble. emergen y operation is possible by setting dip swit h
(SW3<I.B>) on the indoor ontroller board.
[Che k items]
(1)Make sure that no other trouble exist the outdoor unit. Trouble with the outdoor unit prevents emergen y operation.
(If any trouble exists the outdoor unit error ode “P8”will be displayed on the remote ontroller and the trouble position will be shown
on the outdoor ontroller LED. See ele tri wiring diagram of the outdoor unit for details.)
(2)Make sure that there is no trouble with the indoor fan.
Emergen y operation will be ontinuous operation mode due to power ON/OFF (ON/OFF with the remote ontroller is not possible).
[Emergen y operation pro edure]
(1)Set the dip swit h (SW3<I.B>) on the indoor ontroller board to on and off for ooling and - on for heating.
