NOTES:
1. Since the indoor transformer (T) is connected with 220V wiring, if 230V or 240V power is used, change the wiring connection as shown fig : 1
w
.
When power supply is
Since the indoor fan motor (MF1) is connected with 220V 60Hz power, if 200V~240V 50Hz power is used, change the wiring connection as shown fig : 2
w
.
Indoor fan motor (MF1)
for 200V ~ 240V 50Hz.
2. Be sure to refer the outdoor unit electric wiring diagram before wiring of outdoor side unit.
3. Symbols used in wiring diagram above are.

: Terminal block, : Connector.
4. 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 con-
troller board.
[Check items]
(1) Compressor and fan.
(2) Check the trouble position using self diagnostic function. If the result of self diagnosis indicates protective device such as freeze protection is functioning emer-
gency operation is not possible unless the cause is removed.
(3) In emergency operation, the operation made by only ON / OFF circuit breaker manually [ON / OFF with remote controller is not possible].
[Emergency operation procedure]
(1) Cooling is possible by setting

2
ON and
3
OFF for the dip switch (SW3<I.B>) at indoor controller board.
(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.
(4) Thermostat will not function.
(5) Do not cooling for more than 10 hours (the indoor unit heat exchanger can freeze).
