PREPARATION BEFORE OPERATION
Handling of the remote controller
• 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 installing on a wall, etc.
• Install the remote controller holder (option) in a position
where the signal reception sound (beep) can be heard
ON/OFF
from the indoor unit when the button is pressed.

Dry-cell batteries
■ Reference for replacing batteries
Replace the batteries with new AAA alkaline batteries
in the following cases:
·
When the indoor unit does not respond to the remote
control signal.
·
When the display on the remote controller becomes
dim.
·
When a button of the remote controller is pressed, all
displays appear on the screen, and then disappear
immediately.
Do not use manganese batteries. The remote controller
could malfunction.
• The service life of an alkaline battery is about 1 year.
However, a battery whose time limit is approaching
may be exhausted soon. The recommended usable
time limit is indicated (month/year) on the bottom of
the battery.
• To prevent liquid leakage, take out all batteries when
the remote controller is not going to be used for a
long time.
CAUTION:
If liquid from the batteries gets onto your skin or
clothes, wash it well with clean water.
If liquid from the batteries gets into your eyes, wash
them well with clean water and consult a doctor at
once.
• Do not use rechargeable batteries.
• Replace the 2 batteries with new ones of the same
type.
• Dispose of exhausted batteries in the correct man-
ner.
When the remote controller cannot be
used (emergency operation)
When the batteries of the remote controller run out or
the remote controller malfunctions, the emergency op-
eration can be done using the EMERGENCY OPERATION
switch.

pressed, the unit will operate in order of EMER-
GENCY COOL MODE, EMERGENCY HEAT MODE

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.
