Power supply
make sure no wiring has been forgotten and that there are no missing phases or reverse phases.
Wiring
Does wiring between units put in and changed in continuation installation?
Is the unit properly grounded?
Are any of the wiring attachment screws loose?
Is the insulation resistance at least 1 MO?
• *
• Use a 500V mega-tester when measuring insulation
Do not use a mega-tester to low voltage circuit except 220-240V.
Is an earth leakage circuit breaker used as a current operated type which is compatible to the
higher harmonic wave?
Does the earth leakage circuit breaker have appropriate rated current?
Is the size of the piping appropriate?
Refrigerant
piping Is the insulation material for the piping attached securely?
Are both the liquid and gas pipes insulated?
Are the stop valves for both the liquid side and the gas side open?
Did you write down the extra refrigerant and the refrigerant piping length?
Extra refrigerant
Is the indoor unit fully installed?
Indoor unit
When the test run is started, the fan automatically begins turning.
• When a power supply is switched on, when you leave from the outdoor unit, be sure to close the cover plate.
(It becomes the cause of an electric shock).
In field setting for an outdoor unit, make sure to shut down the power and check that there is no residual voltage before
start installing. {It may cause an electric shock.)
THE METHOD OF LOW NIGHT NOISE SETTING USING THE REMOTE CONTROLLER
The functions of the "Low Night Noise Setting" outdoor unit can be set by using the remote controller.
During installation, make the field settings according to the description below, after the service inspection and repair.
Mistakes in the setting could cause malfunctions.
( HOW TO MAKE THE FIELD SETTINGS )
Make the field setting according to "How to make the field settings" which come with the remote controller.
The settings are set by switching between "Mode No.", "FIRST CODE No.", and "SECOND CODE No.".

NOTES
1. Settings are done in a batch for the group. For this reason, when performing group control* using the remote controller
from one unit to set individual outdoor units, set each unit separately (for each connected indoor unit no.) using the
mode number in parentheses. Checking after changing settings can also only be done using the mode numbers in
parentheses. (For group batch control, the display will always read "01" even though the settings have been changed.)
Furthermore, when performing control with two remote controllers*, field settings using a remote controller can only
be done using the main remote controller.
* For details on controlling the units using the remote controllers, see applicable service manual.
2. Do not set any values not shown in the table above.
• For settings other than the above, refer to the caution label or the service manual.
• Low night noise operation and demand operation using an external command requires a demand adapter
PC board (option). For more details, refer to the manual supplied with the adapter.
