NOTES:
• Specifications are based on the following conditions:
– Cooling: Indoor temperature of 27 °CDB/19 °CWB, and outdoor temperature of 35 °CDB/24 °CWB.
– Heating: Indoor temperature of 20 °CDB/15 °CWB, and outdoor temperature of 7 °CDB/6 °CWB.
– Pipe length: 7.5 m, Height difference: 0 m. (Between outdoor unit and indoor unit.).
• Protective function might work when using it outside the operation range.
• *1: Maximum current:
– The maximum value when operated within the operation range.
– The total current of indoor unit and 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.

¢ Automatic airflow adjustment procedures
1. To start the auto setting, use No.32 of setting value in Function Number 26.
2. Run the air conditioner on fan mode (High).
* For instructions on how to operate the air conditioner, refer to the operation manual of the
remote controller.
During automatic airflow adjustment, the mode will be fixed at fan (High).
When this function is active, do not operate the outdoor unit.
3. The air conditioner will run for about 1 to 8 min then stop automatically.
* Do not change the throttles of the inlet and outlet ports during operation.
When used in a group control system, the setting will take about 10 min.
4. Turn the air conditioner off and on again.
5. Check the setting value of Function 26.
* If the setting value has not changed, repeat the procedure from step 2.
CAUTION
When the duct or outlet installations are changed after the Automatic airflow adjustment is completed, repeat the procedure from step 1.

• 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 50 mm or more.
• When installing the outdoor unit, be sure to open the front and left side to obtain better operation
efficiency.

AOYG72-90LRLA
CAUTION
• When the outdoor temperature is 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.

No. Setting item Content
By using the "Low noise mode", the limit of the noise level will be set to decrease
the noise level. The mode comes in 2 levels which can be set accordingly.
1 Low noise mode setting
2 Peak cut mode setting
To turn on the mode, use the external input terminal (CN131).
• By using this mode, the cooling/heating performance may decrease.
• Depending on the operating condition, the noise level may not decrease even if
the Low noise mode is on.
The capacity limit can be selected when operating with the “Peak Cut mode.” The
operation selection can be done by external input terminal (CN132).
The lower the level, the more the effect of energy saving, but the cooling/heating
performance decreases.

Test operation method
¢
Be sure to configure test run settings only when the outdoor unit has stopped operating.
Notices:
• Depending on the communication status between the indoor and outdoor units, it may take several minutes for the system to start operating after settings for the test run are complete.
• After the test run settings are complete, the outdoor units and the connected indoor units will
start operating. Room temperature control will not activate during test operation (continuous operation).
• If a knocking sound can be heard in the liquid compression of the compressor, stop the unit immediately and then energize the crank case heater for a sufficient length of time before restarting the operation.
Test operation setting method (It can be performed in the following two ways)
• Set with test operation setting (refer to installation instructions manual of indoor unit for further details) available in the remote controller.
• "Cooling operation" and "Heating operation" can be set using SELECT button and ENTER button
available on the board of display unit.
(*Make sure to perform the first test operation with cooling operation.)
Set as per the procedure given below.
Symbols in the following table indicate LED status.

WARNING
• Never touch electrical components such as the terminal blocks except the button on the display
board. It may cause a serious accident such as electric shock.
• During the pump-down operation, make sure that the compressor is turned off before you remove the refrigerant piping.
Do not remove the connection pipe while the compressor is in operation with 2-way or g. 3-way
valve open. This may cause abnormal pressure in the refrigeration cycle that leads to breakage
and even injury.
CAUTION
• Perform the pump down operation before disconnecting any refrigerant pipe or electric cable.
• Collect refrigerant from the service port or the 3-way valve if pump down cannot be performed.
• In case of a group control system installation, do not turn the power off until pump down is completed in all outdoor units.
(Group control system installation described in “SPECIAL INSTALLATION METHODS” in the installation manual of the indoor unit.)
