NOTES:
1. Since the indoor fan motor (MF) is connected with 230, 240V power, using 220V power will require a setting change of the dip switch (SW7<I.B>) on the indoor
controller board as shown in fig :
w
1.
Indoor fan motor (MF) for 220V.

2. Since the indoor transformer (T) is connected with 240V power, if 220,230V power is used. Change the wiring connection showing fig :
w
2.
When power supply is
3. Since the outdoor side electric wiring may change be sure to check the outdoor unit electric wiring for servicing.
4. Indoor and outdoor connecting wires are made with polarities, make wiring matching terminal numbers.
5. Symbols used in wiring diagram above are, : Connector,
/
: Terminal block.
6. Emergency operation
If remote controller of microcomputer fails but there is no other trouble, emergency operation is possible by setting dip switch (SW3<I.B>) on the indoor con-
troller board.
[Check items]
(1) Make sure that no other trouble exist the outdoor unit. Trouble with the outdoor unit prevents emergency operation.
(If any trouble exists the outdoor unit error code “P8” will be displayed on the remote controller and the trouble position will be shown on the outdoor controller
board LED. See electric wiring diagram of the outdoor unit for details.)
(2)Make sure that there is no trouble with the indoor fan.
Emergency operation will be continuous operation mode due to power ON/OFF(ON/OFF with the remote controller is not possible).
[Emergency operation procedure]
(1)Set the dip switch (SW3<I.B>) on the indoor controller board to
1
on and
2
off for cooling and
1
-
2
on for heating.
(2)Turn on outdoor unit side circuit breaker, then indoor unit side circuit breaker.
(3)During emergency operation indoor fan runs at high speed but automatic vane remains stop.
(4)Thermostat will not function. Cold air blows out for defrosting during heating thus do not operate defrosting for along time.
(5)Emergency cooling should be limited to 10 hours maximum.
(The indoor unit heat exchanger may freeze).
(6)After every operation, switch the fan connector to FAN1, and set all dip switches (SW3<I.B>) to OFF.
