About Night Quiet Mode
The Night Quiet Mode function reduces operating sound of the outdoor
unit at nighttime. This function is useful if the customer is worried about
the effects of the operating sound on the neighbors.
However, if Night Quiet Mode is running, cooling capacity will be saved.
Setting procedure
Remove the SW5 jumper switch.
Once the settings are complete, reset the power.
NOTE
Install the removed jumper switch as described below. This switch
