NOTES :
1. Since the indoor transformer (T)is connected with 240Vpower. If 220, 230v power is used. change the wiring connection showing fig: W2

230V
When power supply is
220V
2. Since the outdoor side electric wiring may change be sure to check the outdoor unit electric wiring for servicing.
3. Indoor and outdoor connecting wires are made with polarities. make wiring matching terminal numbers.
4. Symbols used in wiring diagram above are. / : Terminal block,
5. Emergency operation
If remote controller or microcomputer fails but there is no other truble,. 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 exists 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 run with the power ON/OFF (ON/OFF with the remote controller is not possible).
[Emergency operation procedure]
(1)Switch the fan connector on the indoor controller board from FAN 1 to FAN 2.
(2)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.
(3)Turn on the outdoor unit side circuit breaker, then the indoor unit side circuit breaker.
(4)During emergency operation indoor fan runs at High speed but auto-vane does not work.
(5)Thermostat will not function. Cold air blows out for defrosting during heating thus do not operate defrosting for a long time.
(6)Emergency cooling should be limited to 10 hours maximum. (the indoor unit heat exchanger may freeze).
(7)After every operation, switch the fan connector to FAN1, and set all dip switches (SW3<I.B>) to OFF.
NOTE: If the drain water lift up mechanism is identified to be defective with the microcomputer doctor during cooling, do not use emergency operation
(it causes drain overflow)
