Avoid installing the unit at a place with quiet background sound as follows.
(1)Rooms with quiet background such as bed room, hospital, or room in a hotel.
(2)Rooms which have no ceiling and a fabric does not block the residence space from the Flow Selector unit.
(3)Rooms which have opening port at the ceiling.
When installing the unit at the above places,separate the unit from the indoor unit (more than 33ft(10m)) and
install the unit at a place so that sound does not transmit into the room such as in the corridor ceiling.
Refer to the installation manual about other cautions for selection of installation place.
