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:
2. Since the outdoor side electric wiring may change be sure to check the outdoor unit electric wiring for servicing.
3. Since the indoor transformer (T) is connected with 220V power, if 230,240V power is used. Change the wiring connection showing fig * : 2.
4. Symbols used in wiring diagram above are, : Connector, : Terminal block.
5. Emergency operation

When power supply is
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.
(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
(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 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. If vane is closed, open the vane by hands.
(4) Thermostat will not function.
(5) Emergency cooling should be limited to 10 hours maximum.
emergency operation is not possible unless the cause is removed.
Emergency operation will be continuous operation mode due to power ON/OFF (ON/OFF with remote controller is not possible).
(The indoor unit heat exchanger may freeze).
