NOTES:
1.Since the indoor fan motor(MF)is connected with 230V power,if 208V power is used,change the dip switch(SW8)on
the indoor controller board as shown in fig:*1.
fig:*1
Indoor fan motor(MF)for 208V.
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,
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) Make sure that no other trouble exist in the outdoor unit.Trouble with the outdoor unit prevents emergency operation.
(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) 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 auto-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 switches(SW3<I.B>) to OFF.
(7) Movement of the vanes does not work in emergency operation,therefore you have to slowly set them manually to the
appropriate position.
