The range that the signal can reach is about 6 m when
the remote controller is pointed at the front of the in-
door unit.
When a button is pressed, one or two beeps will be
heard from the indoor unit. If no sound is heard, op-
erate again.
Use the remote controller carefully.
If it is dropped, thrown or it gets wet, the remote con-
troller may not operate.
When the batteries of the remote controller run out or the remote controller malfunctions, the emergency operation
can be done using the EMERGENCY OPERATION switch.
How to set the batteries and the current

Each time the EMERGENCY OPERATION switch is
pressed, the unit will operate in order of EMER-
GENCY COOL MODE, EMERGENCY HEAT MODE
and STOP MODE.
Then reattach the front lid.

Operation state
•
These units are equipped with an auto restart function.When the main power is turned on, the air conditioner will start
operation automatically in the same mode as the one set with the remote controller before the shutoff of the main
power.
If the unit was set to off with the remote controller before the shutoff of the main power, it will remain stopped even after
the main power is turned on.
If the unit was in the emergency operation before the shutoff of the main power, it will start operation, when main power
comes on, in the same mode as the one set with the remote controller before the emergency operation.
If the unit is operated in “I FEEL...” or “AUTO” mode before power failure, the operation mode (COOL, DRY or HEAT) is
not stored in the memory. When the main power is turned on, the unit decides the operation mode by the initial room
temperature at restart and starts operation again.
This shows that the air conditioner is operating to reach the
target temperature. Please wait until the target temperature

blowing down for 1 hour, the direction of the air
flow is automatically set to position 1 to prevent
condensed water from dropping.
