• 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

Description of “AUTO RESTART FUNCTION”
• 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.

Information for multi system air conditioner
Multi system air conditioner can connect two or more indoor units with one outdoor unit. According to the
capacity, two or more units can operate simultaneously.
• When you try to operate two or more indoor units with one outdoor unit simultaneously, one for the cooling and the other
for heating, the operation mode of the indoor unit that operates earlier is selected. The other indoor units that will start the
operation later cannot operate, indicating an operation state. (Refer to the table of Operation Indicator lamp below.)
In this case, please set all the indoor units to the same operation mode.
• When indoor unit starts the operation while the defrosting of outdoor unit is being done, it takes a few minutes (max.
10 minutes) to blow out the warm air.
• In the heating operation, the indoor unit that does not operate may get warm or the sound of refrigerant flowing may be
heard. This is not a malfunction since the refrigerant continuously flows into the indoor unit that does not operate.

Water may condense and drip from
the horizontal vane if the air

The horizontal vane operates as described below to prevent air from blowing directly on individuals in the room.
When heating operation starts or during defrosting operation, the air flow is
reduced and the upper air flow direction
is set to prevent cold air from blowing
directly on individuals in the room.

indoor unit.
To change the horizontal direction of the air flow, move the vertical vane manually.
■
• Change the direction of the vertical vane (upper), holding the tabs on the vane.
• Adjust the vane before operation starts.
Since the horizontal vane moves automatically, your fingers may be caught.
• Change the direction of the vertical vane (lower), holding
the vane.
Always adjust the vane when the damper is open. Opening the
damper forcibly with hands can cause damage or malfunction.
AIR OUTLET SELECTION
With this function, air comes out simultaneously from the upper and lower air outlets so that the room
can be cooled or heated effectively. This function is set using the switch behind the front grille of the
