wThe air coverage range is the value up to the position where the air speed is 0.25m/sec. When air is blown out horizontally from the unit at the Hi notch position.

The coverage range should be used only as a general guideline since it varies according to the size of the room and the furniture inside the room.

NOTES :

1.Since the indoor fan motor (MF) is connected with 230, 240V power. If 220V power is used, change the dip switch (SW8) on the indoor controller board as shown in fig : w2.

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 mode 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.

[Check items]

(1)Make sure that no other trouble exist 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)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 are 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.

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)
