NOTES :
1. Since the indoor fan motor (MF 1.2) is connected with 230~240V power. If
220V power is used. change the dip switch (SW5<1.B>)on the indoor con-
troller board showing fig:

1.
Indoor fan motor (MF1.2)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.
3. Since the outdoor side electric wiring may change be sure to check the out-
door unit electric wiring for servicing.
When power supply is
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. :PC board insertion tab.
5. Emergency operation
If a trouble occurs with either the remote controller or the indoor microcom-
puter no other truble exists. emergency operation for cooling or heating can
be performed by changing the setting of dip switch (SW3<I.B>) on the
indoor controller board.
(emergency dry operation is not possible.)
[Check items]
(1)Make sure that no other trouble exist the outdoor unit. Trouble with the out-
door 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 con-
troller 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 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 belows 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 emergency 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)
