NOTES:
• Specifications are based on the following conditions: – Cooling: Indoor temperature of 80 °FDB (26.67 °CDB) /67 °FWB (19.44 °CWB), and outdoor temperature of 95 °FDB (35 °CDB) / 75 °FWB (23.9 °CWB). – Heating: Indoor temperature of 70 °FDB (21.11 °CDB) /59 °FWB (15 °CWB), and outdoor temperature of 47 °FDB (8.33 °CDB) /43 °FWB (6.11 °CWB). – Pipe length: 24 ft 6 in (7.5 m), Height difference: 0 ft (0 m). (Between outdoor unit and indoor unit.)
• Protective function might work when using it outside the operation range.
• *1: Maximum operating current is the total current of the indoor unit and the outdoor unit.
• *2: Sound pressure level:
– Measured values in manufacturer’s anechoic chamber. – Because of the surrounding sound environment, the sound levels measured in actual installation conditions might be higher than the specified values here.
• *3: Available on Google Play store or on App Store. For details, refer to the setting manual.

9-1. External input

With using external input function, some functions on this product can be controlled from an external device.
• “Operation/Stop” mode or "Forced stop" mode can be selected with function setting of indoor unit.
• A twisted pair cable (22AWG) should be used. Maximum length of cable is 492 ft (150 m).
• The wire connection should be separate from the power cable line.
¢
The air conditioner can be remotely operated by means of the following on-site work. Unit operation is started at the following contents by adding the contact input of a commercial on/off
switch to a connector on the external control PCB and turning it on.

Setting procedure by using wireless remote controller
WALL MOUNTED
ASU9-15RLS3Y
After reconfirming the items listed above, connect the power supply of the indoor unit.
NOTES:
• Settings will not be changed if invalid numbers or setting values are selected.
• When optional wired remote controller is used, refer to the installation manual enclosed with the remote controller.
Entering function setting mode:
While pressing the POWERFUL button and TEMP. ( ) button simulta­neously, press the RESET button to enter the function setting mode.
Selecting the function number and setting value:
1. Press the TEMP. ( ) ( ) buttons to select the function number. To switch between the left and right digits, press the MIN. HEAT button.
2. Press the POWERFUL button to proceed to value setting. To return the function number selection, press the POWERFUL button again.
3. Press the TEMP. ( ) ( ) buttons to select the setting value. To switch between the left and right digits, press the MIN. HEAT button.
4. Press the MODE button once to send the function setting informa­tion. Confirm that you hear the beep sound.
5. Press the START/STOP button to fix the function setting. Confirm that you hear the beep sound.
6. Press the RESET button to end the function setting mode.
7. After completing the function setting, be sure to disconnect the pow­er supply and then reconnect it.
CAUTION
After disconnecting the power supply, wait 30 seconds or more before reconnecting it. The function setting will not become active unless the power supply is disconnected and then reconnected.

11-2. Custom code setting for wireless remote controller

To interconnect the air conditioner and the wireless remote controller, assignment of the custom code for the wireless remote controller is required.
WALL MOUNTED
ASU9-15RLS3Y
NOTE:
When 2 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 custom code of the remote controller to operate only the air conditioner you wish to set. (4 selections possible.)
Confirm the setting of the remote controller custom code and the function setting. If these do not match, the remote controller cannot be used to operate for the air conditioner.
Air conditioner cannot receive a signal if the air conditioner has not been set for the custom code.
1. Press the START/STOP button until only the clock is displayed on the remote controller display.
2. Press the MODE button for at least 5 seconds to display the current custom code. (Initially set to
.)
3. Press the TEMP. ( ) ( ) buttons to change the custom code be­tween → → → . Match the code on the display to the air condi­tioner custom code. (Initially set to .)
WALL MOUNTED
ASU9-15RLS3Y
4. Press the MODE button again to return to the clock display. The custom code will be changed.
NOTES:
• If no button is pressed within 30 seconds after the custom code is displayed, the system returns to the original clock indicator. In this case, start again from step 1.
The air conditioner custom code is set to prior to shipment. To change the custom code, con-
• tact your retailer.
If you do not know the assigned code for the air conditioner, try each of the custom code (

NOTES:
• If the space is larger than stated above, the condition will be the same as when there is no ob­stacle.
• Height above the floor level should be 2 in (50 mm) or more.
• When installing the outdoor unit, be sure to open the front and left side to obtain better operation efficiency.
CAUTION
• Do not install the outdoor unit in two-stage where the drain water could freeze. Otherwise the drainage from the upper unit may form ice and cause a malfunction of the lower unit.
• When the outdoor temperature is 32 °F (0 °C) or less, do not use the accessory drain pipe and drain cap. If the drain pipe and drain cap are used, the drain water in the pipe may freeze in extremely cold climate. (For reverse cycle model only.)
• In area with heavy snowfall, if the inlet and outlet of the outdoor unit is blocked with snow, it might become difficult to get warm, and it is likely to cause product malfunction. Construct a canopy and a pedestal, or place the unit on a high stand that is locally installed.

*1: Minimum Circuit Ampacity (Calculation based on UL1995) *2: Selected sample based on Japan Electrotechnical Standards and Codes Committee E0005. As
the regulations of wire size and circuit breaker differ in each country or region, select appropriate de­vices complied to the regional standard.
*3: Maximum Circuit Breaker *4: Limit voltage drop to less than 2%. If voltage drop is 2% or more, increase cable conductor size.
