Remote controller custom code setting
Use the following steps to select the custom code of the remote controller. (Note that the
air conditioner cannot receive a signal if the air conditioner has not been set for the cus-
tom code.)
(1) Press the START/STOP button until only the clock is displayed on the remote control-
ler display.
(2) Press the MODE button for at least 5 seconds to display the current custom code
(initially set to A).
(3) Press the SET TEMP. (

) (
▼
) button to change the custom code between
A
→
B
→
C
→
D. Match the code on the display to the air conditioner custom code.
(4) Press the MODE button again to return to the clock display. The custom code will be
changed.
If no buttons are pressed within 30 seconds after the custom code is displayed, the
system returns to the original clock display. In this case, start again from step 1
The air conditioner custom code is set to A prior to shipment.
The remote controller resets to custom code A when the batteries in the remote control-
ler are replaced. If you use a custom code other than custom code A, reset the custom
code after replacing the batteries.
If you do not know the air conditioner custom code setting, try each of the custom codes
(A
→
B
→
C
→
D.) until you find the code which operates the air conditioner.
12. TEST RUN
WARNING
Do not turn on the power until all installation work is complete.
CAUTION
Always turn on the power 12 hours prior to the start of the operation in order to ensure
compressor protection.
Check items
(1) Is operation of each button on the remote control unit normal?
(2) Does each lamp light normally?
(3) Do air
fl
ow direction louvers operate normally?
(4) Is the drain normal?
(5) Do not have an abnormal noise and vibration during operation?
• Do not operate the air conditioner in test run for a long 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 the air conditioner and press
the test run button with the tip of a ballpoint pen, etc.)

(3) Press the START/STOP button to stop the test run.
13. CUSTOMER GUIDANCE
Explain the following to the customer in accordance with the operating manual:
(1) Starting and stopping method, operation switching, temperature adjustment, timer, air
fl

(2) Air
fi
lter removal and cleaning, and how to use the air louvers.
(3) Give the operating manual to the customer.
14. ERROR CODES
If you use a wireless remote controller, the lamp on the photo detector unit will output error
codes by way of blinking patterns. If you use a wired remote controller, error codes will ap-
pear on the remote control display. See the lamp blinking patterns and error codes in the
table. An error display is displayed only during operation.
