2.2.1 Placement considerations
Placement of indoor units should take account of the following considerations:
To prevent the refrigerant noise from disturbing the people in the room, keep at least 5 m of piping between the
occupied room and the MS box.
If there is no false ceiling in the room, please add sound insulation around the piping between the MS box and the
indoor unit, or keep a much longer distance between the MS box and occupied room.
To prevent excessive noise or vibration during operation, suspension rods or other weight-bearing fixings should
typically be able to bear twice the unit’s weight.
