• Do not operate the air conditioner in the running state for a
long time.
• Test running
When the air conditioner is run by pressing the remote
controller TEST RUN button, the OPERATION and TIMER
lamps fl ash slowly at the same time.
[OPERATION METHOD]
• For the operation method, refer to the operating manual.
• The outdoor unit may not operate depending on the room
temperature. In this case, press the TEST RUN button on
the remote controller while the air conditioner is running.
(Point the transmitter section of the remote controller toward

TEST RUN
The air conditioner signal code is set to A prior to ship-
ment. Contact your retailer to change the signal code.
The remote controller resets to signal code A when the
batteries in the remote controller are replaced. If you use a
signal code other than signal code A, reset the signal code
after replacing the batteries.
If you do not know the air conditioner signal code setting,
try each of the signal codes (
) until you fi nd
the code which operates the air conditioner.
When two or more air conditioners are installed in a room and
the remote controller is operating an air conditioner other than
the one you wish to set, change the signal code of the remote
controller to operate only the air conditioner you wish to set (four
selections possible).
When two or more air conditioners are installed in a room,
please contact your retailer to set the individual air conditioner
signal codes.
• Confi rm the setting of the remote controller signal code and
the printed circuit board setting.
If these are not confi rmed, the remote controller cannot be
used to operate for the air conditioner.
Selecting the Remote Controller Signal Code
Use the following steps to select the signal code of the remote
controller. (Note that the air conditioner cannot
receive a signal code if the air conditioner has
not been set for the signal code.)
①
Press the START/STOP button until only
the clock is displayed on the remote con-
troller display.
②
Press the MODE button for at least five
seconds to display the current signal code
(initially set to ).
③
Press the SET TEMP. (
) (
) but-
ton to change the signal code between
.
Match the code on the display to the air
conditioner signal code.
④
Press the MODE button again to return to
the clock display. The signal code will be
changed.

FUNCTION SETTING
• This procedure changes to the function settings used to control the indoor unit according to the installation conditions. Incorrect
settings can cause the indoor unit malfunction.
• After the power is turned on, perform the “FUNCTION SETTING” according to the installation conditions using the remote
controller.
• The settings may be selected between the following two: Function Number or Setting Value.
• Settings will not be changed if invalid numbers or setting values are selected.
Entering the Function Setting Mode
• While pressing the FAN button and SET TEMP. ( ) simultaneously, press the RESET button to enter the function setting
mode.
STEP 1
Setting the Remote Controller Signal Code
Use the following steps to select the signal code of the remote controller. (Note that the air con-
ditioner cannot receive a signal code if the air conditioner has not been set for the signal code.)
The signal codes that are set through this process are applicable only to the signals in the
FUNCTION SETTING. For details on how to set the signal codes through the normal process,
refer to SELECTING THE REMOTE CONTROLLER SIGNAL CODE.
①
Press the SET TEMP. ( ) ( ) button to change the signal code between
.
Match the code on the display to the air conditioner signal code. (initially set to )
(If the signal code does not need to be selected, press the MODE button and proceed to
STEP 2.)
②
Press the TIMER MODE button and check that the indoor unit can receive signals at the dis-
played signal code.
③
Press the MODE button to accept the signal code, and proceed to STEP 2.
The air conditioner signal code is set to A prior to shipment.
Contact your retailer to change the signal code.
The remote controller resets to signal code A when the batteries in the remote controller are replaced. If you use a signal
code other than signal code A, reset the signal code after replacing the batteries.
If you do not know the air conditioner signal code setting, try each of the signal codes (
) until you fi nd the code
which operates the air conditioner.
