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 furniture inside the room.

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)Compressor and fan.
(2)Check the trouble position using self diagnostic function. If the result of self diagnosis indicates protective device such as freeze protection is functioning
emergency operation is not possible unless the cause is removed.
Emergency operation will be continuous operation mode due to power ON/OFF (ON/OFF with remote controller is not possible). [Emergency operation procedure]
(1)Set the dip switch (SW3 <I.B>) on the indoor controller board to 1 • 2 on and 3 off for cooling.
(2)Turn on outdoor unit side circuit breaker, then indoor unit side circuit breaker in this order.
(3)During emergency operation indoor fan runs at high speed but automatic vane remains stop. If vane is closed, open the vane by hands.
(4)Thermostat will not function.
(5)Emergency cooling should be limited to 10 hours maximum. (The indoor unit heat exchanger may freeze).
