(1)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.
(2)Turn on outdoor unit side circuit breaker, then indoor unit side circuit breaker.
(3)During emergency operation, indoor fan runs at high speed but automatic vane does not work.
(4)Thermostat will not function. Cold air blows out for defrosting during heating thus do not operate defrosting for a long time.
(5)Emergency cooling should be limited to 10 hours maximum. (The indoor unit heat exchanger may freeze.)
(6)After every emergency operation, set all dip switch (SW3<I.B>) to OFF.
(7)Movement of the vane does not work in emergency operation, therefore you have to slowly set them manually to the appropriate position.

1.Since the indoor fan motor(MF)is connected with 230V power, using 208V power will require a setting change of the dip switch(SW8<I.B>) on
indoor controller board as shown in fig:*1.
NOTES:
Indoor fan motor(MF)for
208V.
fig:*1
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, :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.
6.Fasten terminal of the terminal board "TB4" equips lock system.
To remove the fasten terminal, pull it while pressing the protruding portion (locking lever) of the terminal.
Connection of the fasten terminal, protruding portion should face upward.
(1)Make sure that no other trouble exist in the outdoor unit. Trouble with the outdoor unit prevents emergency operation.
(If any trouble exists in 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 operation mode. (ON/OFF by the remote controller is not possible.)
