[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 to

1 2 onand 3 off 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 :

2. Since the indoor transformer (T) is connected with 220V power, if 230, 240V power used. Change the wiring connection showing fig : W2.
